Java output from process buider overwritten when using BufferedReader
|
<p>I'm trying to run an external program in Java and to read the output. The program is a Linux application in C++ that runs a data mining algorithm and prints the patterns found on standard output. I want to be able to read that output from my Java app and to show the patterns using a table. The problem is that the size of the output is quite big (as a test it produces 6.5MB in about 30 seconds). I'm using ProcessBuilder and reading the output using an InputStreamReader buffered using a BufferedReader as you can see in the following code:</p>
<pre><code> String[] cmd = {"./clogen_periodic", selected, support, "-t 4"};
Process p = new ProcessBuilder(cmd).start();
input = new BufferedReader (new InputStreamReader(p.getInputStream()));
while ((line = input.readLine()) != null) {
...
process line;
...
}
</code></pre>
<p>The problem is that the output gets corrupted. When I execute the same program on a console the output is correct but when I use the Java app some lines are merged. More precisely output should be like this</p>
<pre><code> TMEmulation log_pseduo_allocation (34985) (2 45 76 89 90)
__divw clock timer (8273) (4 6 67 4 2)
</code></pre>
<p>but it is like this </p>
<pre><code> TMEmulation log_pseduo_allocation (34985) (2__divw 45clock 76timer (89 8273) 904) (6 67 4 2)
</code></pre>
<p>Any idea about the possible problem?</p>
<p>Thanks a lot in advance,
Patricia</p>

i want to display this listview on scrolling
|
<p>I'm completely stumped on this one. I have three different lists that need to be displayed on the screen.
I've tried using a ScrollView with a LinearLayout child, and putting my ListViews in the LinearView, but all of the ListViews lock to a fixed height with scroll bars. Using other kinds of Layouts means no scrolling.</p>

shortcut to existentially define variable in javascript
|
<p>To avoid clobbering existing variables, I have code like this</p>
<pre><code>window.x = typeof x != "undefined" ? x : {}
</code></pre>
<p>Which seems like a very long winded way to define something, but necessary to avoid console errors.</p>
<p>I tried this out instead, and it seems to work ok. Is it ok to define a variable like this?</p>
<pre><code>window.x=window.x||{}
</code></pre>
<p>Or even in the global scope...</p>

Get count of inner objects

CSimpleIniA - method of wrapper class doesn't read config file value
|
<p>I wrapped <a href="http://code.jellycan.com/simpleini/" rel="nofollow">CSimpleIniA</a> in a Config class to manage configuration options in a 'config.ini' file.</p>
<p>In the example I provide, <code>sample_size</code> is read in the <code>Config</code> constructor.
When <code>readSampleSize()</code> is called, the value of the configuration file is returned.</p>
<p>By contrast, <code>readInitialPos()</code> should (what I expected) be able to read the <code>config.ini</code> and return the value of <code>inital_pos</code>. Instead, it returns the default value, the third argument <code>70000</code>.</p>
<p>I don't understand why this second method is not working. </p>
<p>config.hpp</p>
<pre><code>class Config {
private:
unsigned long int sample_size;

Turn first character of str capitalized but ignore one or two letter words

<p>I am a newbie and this is a tough one for me.</p>
<p>I have a text inside a variable:</p>
<pre><code>$bio = 'text, text, tex ...';
</code></pre>
<p>I can use the <strong>ucfirst</strong> php function to make word in the text start with an uppercase letter.</p>
<p><strong>The problem is I don't want the words with one, two or three letters be capitalized</strong> becouse it would look unprofessional.</p>
<p><strong>IMPORTANT:</strong> But I want also to keep the <strong>letter "I"</strong> capitalized since it's proper english grammar.</p>
<p><strong>So a text like:</strong>
this is a text without ucfirst function and i think it needs some capitalizing</p>
<p><strong>Would look like:</strong>
This is a Text Without Ucfirst Function and <strong>I</strong> Think it Needs Some Capitalizing</p>
<p>Any ideas?</p>

Permutation of sequence?

<p>For example if the amount of numbers is 3, I want to display:</p>

0 0 1
0 0 2
0 1 0
0 1 1
0 1 2
0 2 0

2 0 1
2 0 2
2 1 0
2 1 1
2 2 0
2 2 1
2 2 2

<p>After the formation of the table; </p>

<li>Every number will put into the table randomly from <strong>R1</strong> to <strong>R3</strong> just once. </li>
<li>Every number necessarily must be in every rows.</li>
<li>If current number was in B side (of colums), next time (i mean, in next row) must be in A side or just the opposite. </li>

How to reload table view with new data
|
<p>I am calling other view controller name "cityState" on button click which has table in it.
code for calling that view on button click(which has table): </p>
<pre><code>[self presentModalViewController:cityState animated:YES];
</code></pre>
<p>now in this view controller I am loading my table with data, its working fine for first time.<br>
For example numberofRowsInSection is like: </p>
<pre><code>-(NSInteger) tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
SingleTon *s = [SingleTon sharedInstance1];
NSMutableArray *x;
rn =[s getRName:x];
NSLog(@"rname : %@",rn);
return [rn count];
[s release];
[ss release];
[x release];
}
</code></pre>
<p>I have a button on this view, and on button press I am going back to the view from which I called this cityStae view </p>
<pre><code>//code for button click
[self dismissModalViewControllerAnimated:YES];
</code></pre>
<p>Now I when I am back on the first view, here I am changing the value of rn (as rn I am using in table view) and calling the table view again with same button click as I did first time, view is called and it is showing with old value of rn and I can see at this time of call NSLog in my numberofRowsInSection is not reached. So the old table with old data is displayed.<br>
My question is <strong>how to show table with new data.</strong>? </p>

My confusion is about the Book constructor given in the middle (the yellow box with the heading "Book"). As every function in javascript is an instance of Function prototype, shouldn't this box (Book) has a <strong>proto</strong> property linking it to prototype of <strong>Function</strong>.? </p>

A problem on using x==Y or (x-y)==0 to control the if condition

for (int j2 =0; j2<2;j2++)
{
System.out.println("j1="+j1+"j2="+j2+" "+temp1.get(j1)+"----"+temp2.get(j2));
int xyz = temp1.get(j1)-temp2.get(j2);
System.out.println("the difference is "+ xyz);
if (temp1.get(j1)==temp2.get(j2))
{
System.out.println("find match");
}
}
}
</code></pre>
<p>The program prints out sth like</p>
<p>j1=0j2=0 7698380----7698380</p>
<p>the difference is 0</p>
<p>Even the two values, temp1.get(j1) and temp2.get(j2) do overlap, the "if" part just did not go through. If I change the <code>if (temp1.get(j1)==temp2.get(j2)) to
if (xyz == 0)</code></p>
<p>Then the result will look like</p>
<p>j1=0j2=0 7698380----7698380</p>
<p>the difference is 0</p>
<p>find match
`</p>
<p>I think the two conditions for controlling the if loop should be the same, why the result if so different? Thanks a lot for the answer.</p>

Sending out notification email to user on user-defined date in php
|
<p>I am making a feature on my website that allows the user to enter a task they need to finish by a certain date. The website will then notify them by email when it gets near the date, defined by the user (1 day before due date, 2 hours before due date and so on..) I am totally new to notifications and am unsure how to ask this question but here it is in an example of what I want done... </p>
<p><strong>In an example:</strong></p>
<ol>
<li>The user types in "Need to call boss." </li>
<li>The user enters in the date selector, May 31st at 11:00 AM. </li>
<li>And then clicks the "Notify me 1 day before"</li>
<li>They enter their email and click submit. </li>
</ol>
<p>My website will then notify them by email on May 30th at 11:00 AM reminding them to call their boss... </p>
<p>I have looked around and have noticed somethings pointing to CRON jobs.. I looked at that and am unsure if that is the way to go... </p>
<p>Thanks for the time!</p>

Draw on an image
|
<p>Here is my problem. I am currently working on an android application that is handling images. When the application first starts, I have a list of categories (Food, Transport, Emergency ...). So I click on a category for example Food. I find myself in the second activity where I have subcategories (Fruit, Meat, Fish ...). So let's say I click on Fruit. I end up in the third activity which displays images (like in a gridview) of different fruits. I can either click on a fruit to zoom it or I can drag & drop it to the bottom of the activity where I have 3 dropzone that are here for me to create a sequence of images and save it.</p>
<p>So back to my problem, when I zoom on an image I want to be able to add a drawing feature. I want to be able to draw on the image when I click on the menu button of the phone and when I select "Draw". I tried to draw on an image but the drawing lines are always going underneath the pictures so I can't see them. Besides, I want to be able to save the image afterwards and I can't seem to find a way to my problem.</p>
<p>Could someone help me please?</p>
<p>I tried using BitmapFactory but it got me nowhere...</p>

Sort a list by multiple attributes?
|
<p>I have a list of lists (which could have been tuples, but I digress) in a format such as:</p>
<pre><code>[12, 'tall', 'blue', 1]
[15, 'tall', 'black', 3]
[13, 'tall', 'blue', 8]
[9, 'short', 'blue', 3]
[1, 'short', 'black', 2]
[2, 'short', 'red', 9]
[4, 'tall', 'blue', 13]
</code></pre>
<p>If I wanted to sort by one element, say the tall/short element, I could do it via <code>s = sorted(s, key = itemgetter(1))</code></p>
<p>If I wanted to sort by BOTH tall/short and colour, I could do the sort twice. Once for each element. However, this is computationally ridiculous. Is there a quicker way?</p>

getElementById id does not exist
|
<p>I have run into a problem with getElementById again.. I never quite understood the behaviour of this method, as simple as it should be, it often doesn't work for me.</p>
<p>What I have now is a HTML page that contains:</p>
<pre><code><div id="vraag">
ha
</div>
<div id="antwoorden">
</div>
<div id="controls">
<form name="controlform">
<input type="button" name="back" disabled value="<" onClick="goBack();" />
<input type="button" name="forth" value=">" onClick="goForth();" />
</form>
</div>
</code></pre>
<p>I have attached a javascript file that does several (working) things, among which is this:</p>
<pre><code>document.getElementById['vraag'].innerHTML = 'ho';
</code></pre>
<p>However, when I click the button that calls this, the firefox error console says:
<code>Error: document.getElementById.vraag is undefined</code></p>
<p>Sadly, the only think I can think of is.. It simply is! I have used this method in very similar environments and that still works, so I can't for the life of me figure out why this doesn't work..</p>

<p>I have a strange issue. Im sending out email alerts when remarks get added to a form. Basically each remarks has its own individual id, but multiple remarks can attached to certain form.</p>
<p>In this scenario I have 3 remarks that I added. Two were added to 1 form and the last to a different form. So I would like it just to send 2 forms. The email is sending out 3 forms. I understand that 3 beans will get populated, but 2 will have the same data because 2 remarks belong to the same form. I tried some algorithms I seen posted on here for dups in and what not, but I guess the code is not recognizing duplicate elements because the remarks each have their own id??</p>
<p>For iteration purposes the JSP requires I throw the list of <code>hotParts</code> into an additional <code>ArrayList</code></p>
<p>This is the code..there is more to it, but this is the part that matters</p>
<p>Thanks</p>
<pre><code> try
{
List<Object> dataList = new ArrayList<Object>();
Set<Long> ids = new HashSet<Long>();
for (HotPartsRemarkBean remark : latestHotPartRemarks)
{
ids.add(remark.getHpId());
}
for ( Long id : ids)
{
hotPart = hotPartsDAO.getHotPartById(id);
dataList.add( hotPart ); //List Of Hot Parts Beans
}
THIS WORKS!!!!!!! :)

Access Contents In An Iframe jquery
|
<p>I have a textarea in an iframe. When I try to do any type of jquery manipulation in the textarea it will not respond. </p>
<p>The text area initially loads data in the iframe fine with this simple code..</p>
<pre><code>//txtHozSliderEmail is the textarea in the iframe
$('#txtHozSliderEmail').val(notificationTemplate.Body)
</code></pre>
<p>but when I change the value of notificationTemplate.Body on subsequent calls, the data from the first call displays. The textarea wont update. I verified that notificationTemplate.Body has different data in it on every call so its not that. </p>
<p>The iframe is nested inside the main page.</p>
<p>When I check the "frames" collection I can see it has 2 frames how can I see the names of them? It seems the iframe has no id when I look at it in the html. Do I have to give it an "id" to access it or some other attribute?</p>
<p>The iframe is on the same domain/server I am not accessing an outside domain. The iframe is being used in the jHtmlArea.js library</p>
<p>Here the code in the library that is creating the iframe:</p>
<pre><code> var iframe = this.iframe = $("<iframe/>").height(textarea.height());
iframe.width('580px');
iframe.height('180px');
//iframe.width(textarea.width() - ($.browser.msie ? 0 : 4));
var htmlarea = this.htmlarea = $("<div/>").append(iframe);

How to retrieve values from arrays and check if they match
|
<p>I am learning to program in php and I have a little problem.
I have two arrays:<br>
Array A:</p>
<pre><code>array(10){
[0]: string(10) "2012-08-01"
[1]: int 1
[2]: string(10) "2012-08-03"
[3]: int 1
[4]: string(10) "2012-08-07"
[5]: int 2
[6]: string(10) "2012-08-09"
[7]: int 2
[8]: string(10) "2012-08-27"
[9]: int 1
}
</code></pre>
<p>Array B:</p>
<pre><code>array(4){
[0]: string(10) "2012-09-04"
[1]: string(10) "2012-09-06"
[2]: string(10) "2012-09-08"
[3]: string(10) "2012-09-10"
}
</code></pre>
<p>I want to check if the first element from Array A equals the first element from Array B, if it does then write second element (in this case <code>1</code>) from array A to an new Array C (one dimensional) else don't write anything in an array C and next check if element with index 2 from an array A equals second element <code>[1]: string(10) "2012-09-06"</code> from an array B if so the write fourth element (<code>[3]: int 1</code>) from an array A to an array C etc. so an array C would have int elements only.
If someone could help me out how to sort this out please I would be very happy </p>

Generate values for str.format style template strings from formatted output

<p>This might seem like a wierd requirement, but I am looking for a good implementation to do this.</p>
<p>I have a dict like</p>
<pre><code>vals = dict(red='#F00', green='#0F0', blue='#00F')
</code></pre>
<p>and a string like</p>
<pre><code>tpl = '{red}:{green}:{blue}'
</code></pre>
<p>and the <code>str.format</code>ted output</p>
<pre><code>output = tpl.format(**vals)
</code></pre>
<p>All is well till here. However, I now need to do the reverse of this. I have to turn a string like <code>'#F00:#0F0:#00F'</code> into a dict of the values that we previously started with. Of course, I could just <code>split</code> and <code>strip</code> the string and take the values I need, but it will fail in the event the <code>tpl</code> string should change.</p>
<p>Any good ideas on how I can do this (If it can even be done, that is)?</p>

<p>I am developing an android application,I want to my application automatically invoked,when I switch on my device.so i used this permission <code><uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /></code> in my application's manifest.xml file and i used service , activity and register Broadcast receiver in manifest.xml file.but I got foreclose error appear in when will i start up my device.How solve this proplem.
My Receiver code given bellow
context.startActivity(new Intent(context,ServicesDemo.class));<br>
//In my mainfest.xml for myReceiver</p>
<pre><code><receiver android:name=".MyReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.HOME" />

</code></pre>
<p>I got this exception <code>java.lang.RuntimeException: Unable to start receiver com.servicedemo.MyReceiver: android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?</code></p>

Javascript Inheritance and this
|
<p>Lets say I have a namespace called ns and ns has to functions on it:</p>
<pre><code>ns = {};
ns.Foo = function(message, fn){
this.message = message;
fn.call(this);
};
ns.bar = function() {
alert('Hello, world!');
};
</code></pre>
<p>And I call it like this:</p>
<pre><code>var foo = new Foo('My Message', function() {
bar();
});
</code></pre>
<p>I get an error saying bar() is undefined. But if I call it this way:</p>
<pre><code>var foo = new Foo('My Message', function() {
this.bar();
});
</code></pre>
<p>It works. Is there a way to structure my JavaScript so I can just call bar() without the this?</p>
<p>Thanks!</p>

High precision calculations with mutable class in Java
|
<p>I'm designing a tool using Java 6, that will read data from Medical Devices. </p>
<p>Each Medical Device manufacturer implements its own Firmware/Protocol. Vendors (like me) write their own interface that
uses the manufacturer's firmware commands to acquire data from the Medical Device. Most firmwares will output data in a cryptic fashion, so the vendor receiving it, is supposed to scale it by doing some calculations on it, in order to figureout the true value. </p>
<p>Its safe to assume that medical data precision is as important as financial data precision etc. </p>
<p>I've come to the conclusion of using BigDecimal to do all numerical calculations and store the final value. I'll be receiving a new set of data almost every second, which means, I'll be doing calculations and updating the same set of values every second. Example:Data coming across from a ventilator for each breath.</p>
<p>Since BigDecimal is immutable, I'm worried about the number of objects generated in the heap every second. Especially since the tool will have to scale up to read data from lets say 50 devices at the same time.</p>
<p>I can increase the heap size and all that, but still here's my questions....</p>
<p>Questions</p>
<ol>
<li><p>Is there any mutable cousin of BigDecimal I could use?</p></li>
<li><p>Is there any existing opensource framework to do something like this?</p></li>
<li><p>Is Java the right language for this kind of functionality?</p></li>
<li><p>Should I look into Apfloat? But Apfloat is immutable too. How about JScience?</p></li>
<li><p>Any Math library for Java I can use for high precision </p></li>
<li><p>I'm aiming for a precision of upto 10 digits only. Dont need more than that. So whats the best library or course of action for this type of precision?</p></li>
</ol>
<p>Thanks

<p>This works fine when the property file I want is in the current package. However, I want to package this application as a JAR and define and override with a new properties file where I use it. Is there a way to load the first resource named "props.properties" that is on the classpath?</p>
<p>I want it to be as easy to override the properties file via command line:</p>
<pre><code>java.exe -classpath props.properties;myJar.jar com.test.MyApp

Better to change protected to public? or create another method that calls the superclass
|
<p>I'm trying to create a game using the best practices to my knowledge.
I have:</p>
<ul>
<li>a <code>VisibleObject</code> with a <code>protected void draw(Canvas c)</code> function</li>
<li>a <code>MapTile</code> that <code>extends VisibleObject</code> to draw itself.</li>
<li>a <code>Map</code> class that contains a LinkedList of MapTiles, <code>tiles</code>.</li>
</ul>
<p>In the <code>Map</code> class i wanted a loop like this:</p>
<pre><code>public void draw(Canvas c){
for(MapTile tile : tiles){
tile.draw(c);
}
}
</code></pre>
<p>But i realised i could not call draw upon each tile because it's a protected method in <code>VisibleObject</code>.
I can think of 3 possible solutions:</p>
<ol>
<li>Just change <code>protected</code> to <code>public</code> in <code>VisibleObject</code>.</li>
<li>Create a public method of MapTile that just calls <code>super.draw(c)</code> (I think that's valid syntax?)</li>
<li>change the for loop in Map to something like this, which i believe would make it valid. </li>
</ol>
<p>New Loop: </p>
<pre><code>MapTile current;
for(MapTile tile : tiles){
current = tile;
current.draw(c);
}
</code></pre>
<p>Which solution would be better programming practice?</p>

Is it OK to program a method body inside of an event?

<p>I recently saw some code from a college teacher where he had something like this:</p>
<pre><code>public void Button1_Click(blabla)
{
//His code was here.
}
</code></pre>
<p>Isn't it considered better programming practice to call a method to do the dirty work, that way if the method changes you only have to change the method itself and not the event? (Less chance of breaking something)</p>
<pre><code>public void Button1_Click(blabla)
{
DoSomething();
}
public void DoSomething()
{
//The actual code here.
}

python: select a sublist with a list length limit
|
<blockquote>
<p>players = [ a long list of (id, float) tuples with each id unique,
order by highest float]</p>
<p>on_teams = [ a list of unique ids, every on_teams id is also in the
players list]</p>
</blockquote>
<pre><code>picked = set(on_teams)
best_remaining = []
for best_player in players:
if best_player[0] not in picked:
best_remaining.append(best_player)
if len(best_remaining) == 5: break
</code></pre>
<p>When I use six lines of code to do a simple thing, such as "get the five best remaining players", I wonder if there isn't a more elegant, pythonic solution. It's a simple problem, no doubt, but is there a better way to code it?</p>
<p>UPDATE:
My code run 100,000 times, runs in 0.24 secs. When I run:</p>
<pre><code>best_remaining = [(id, float) for id, float in players if id not in picked][:5]
</code></pre>
<p>The code runs in 4.61 secs (100,000x). So the code looks and scans nicer, but it create the whole list then slices it. So now my question is a little different. With speed as a constraint, is there a better way to code up the search for the '5 best remaining players`?</p>
<p>UPDATE:</p>
<pre><code>best_remaining = list(islice((p for p in players if p[0] not in picked), 5))
</code></pre>
<p>This code runs trivially longer than my code. To me at least, it has the value of a list comprehension. And best of all, it shows me a good place to work on my code habits. Thanks</p>

Weird onclick behavior of images on home screen widget
|
<p>I wrote a home screen widget with one image on it. When the image is clicked, browser will be opened for a url link.
Generally, it is working. But a weird thing is that, when I click background, then click the picture, the browser will not be open. Until I click the second time on the picture, the browser opens. The steps to reproduce is below:</p>
<ol>
<li>Click on the home screen widget background.</li>
<li>Click on the image on the home screen. The browser is not opened.</li>
<li>Click on the image again. The browser is opened.</li>
</ol>
<p>If I didn't click on the background, the image will react to click very well, i.e. browser will be open when the image is clicked the first time.</p>
<p>The widget XML file is as below:</p>
<pre><code><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/widget"
android:layout_width="320dip" android:layout_height="200dip"
android:background="@drawable/prt_base"
>
<ImageView android:id="@+id/picture1"
android:layout_width="134dip"
android:layout_height="102dip"
android:layout_marginLeft="62dip"
android:layout_marginTop="6dip"
android:scaleType="center"
android:src="@drawable/picture1"
/>
</RelativeLayout>
</code></pre>
<p>The code to set OnClick on the picture1 ImageView is as below:</p>
<pre><code> defineIntent = new Intent(Intent.ACTION_VIEW, Uri
.parse("http://www.google.com"));
pendingIntent = PendingIntent
.getActivity(context,
0 /* no requestCode */,
defineIntent, 0 /* no flags */);
updateViews.setOnClickPendingIntent(
picId, pendingIntent);
</code></pre>

Using ItemType for strongly typed repeater control?

<p>Okay, so I looked up some cool stuff about strongly typed repeater controls... the only issue is that it won't work. I have a <code>List<Entry></code> that I've bound my repeater to. I just want to display the data. Normally I use <code>((Entry)(Container.DataItem))</code>, but from what I've read I can just declare the type in the ItemType. </p>
<p>Well... that's what I tried to do, but I get nothing. What am I messing up here?</p>
<pre><code><asp:Repeater ID="UserRptr" ItemType="HROpenEnrollment.Classes.Entry" runat="server">
<ItemTemplate>
<ul class="UserList">
<li class="CompoundField">
<%# ???? I can't use Item here. %>
</li>
</ul>
</ItemTemplate>
</asp:Repeater>
</code></pre>

<p>what i tried is, when a user click on thumb, i store the data as text in the some hidden element ( replacing text), and with the new page opens, i am loading the element to retrieve the data, what i was assigned. but the dynamic content is event updated, i am only getting the static data, what the element has... is it not possible to get the dynamic data? - as a sample example :</p>
<p>thumb page js :</p>
<pre><code>var i=0;
$('a').click( function (e) {
e.preventDefault();
i++;
$('strong').text(i);
})
</code></pre>
<p>i am updating the strong's value each time on click..
the new page loading the prev, pages strong element.</p>
<pre><code> $(document).ready(function(){
$('body').load('index.html strong', function (data) {
console.log('loaded');
})
})
</code></pre>
<p>but i see, only the static data. not dynamic data i assigned. any clue to fix this? or any other way to pass data, apart from get and post method?</p>

Get image out, one by one, from a "images" directoy, using - PHP
|
<p>OK I have a folder with ALL website images (news category ones, only, of course) at only one location called "images/pictures". That folder is PHP controlled. After submitting news to my website, GD (after resizing and stuff) stores images to that location. That works perfect. Even thus, after PHP controlled removal of news from CP, PHP automatically deletes those unnecessary files, images, given from MySql entries. That works perfect.</p>
<p>But, as time goes on.. lots of images left in folder due to sloppy DB/foder backups, changes or some experiments. Even more, recently I had a mess with that folder, so now I have lots of (unnecessary) images in that folder ready to be deleted.</p>
<p>Anyway, I have an idea how to do that.</p>
<ol>
<li><p>PHP to read all images from that directory at first,</p></li>
<li><p>And get every file out, one by one, as a string for while loop (ready to be controlled by MySql for deleting or not).</p></li>
</ol>
<p>Any advice how to achieve that by using PHP? </p>

<p>I'm using function to detect my website visitors browser type but later i found there many visits comes with undetectable browsers so i might needs to do some update to my browsers user agent list. </p>
<p>this is my list of browsers with browser name as array key and user agent as value. </p>
<pre><code>$browsers = array(
'Opera' => 'Opera',
'Mozilla Firefox'=> '(Firebird)|(Firefox)',
'Galeon' => 'Galeon',
'Mozilla'=>'Gecko',
'MyIE'=>'MyIE',
'Lynx' => 'Lynx',
'Netscape' => '(Mozilla/4\.75)|(Netscape6)|(Mozilla/4\.08)|(Mozilla/4\.5)|(Mozilla/4\.6)|(Mozilla/4\.79)',

Replace New with other solution?
|
<p>This code has lot of trouble for my AIR 2.0 Native process which I tried to launch Java from AIR application, then the Java.exe terminate itself in the Windows Task manager, I found that <code>new MidiTest()</code> was the caused. Is there a better solution for new instance?</p>
<pre><code> public static void main(String[] arg) {
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
while (!(speed.equals(speed_stop))) {
try {
speed = in.readLine();
if(!(Global.newPlayer.equals("1"))){new MidiTest();}
} catch (IOException e) {
System.err.println("Exception while reading the input. " + e);
}
}
}
private MidiPlayer player;
public MidiTest() {
System.out.println("Start player");
// /*
}

Character encoding when passing value to PHP in GET URL parameter
|
<p>I have the following HTTP GET parameter in my URL what I'm trying to return in a query:</p>
<pre><code>Tablets & Phones
</code></pre>
<p>When I do <code>var_dump($_GET['my_get_param'])</code>, the string is not full, instead I'm getting <code>"Tablets "</code> (note the space afterwards.) How can I encode the string to get the desired value? I have been trying urlencode and html_specialchars, but without any result.</p>
<p><code>var_dump(urlencode($_GET["my_get_param"))</code> is returning <code>"Tablets+"</code>.</p>
