Export Captured Movie Only plays in Landscape Mode, and is Rotated
|
<p>Before I post a lot of code here is the scenario:</p>
<ol>
<li>Using code based on AVEditDemo from WWDC, I capture a movie using the standard control in portrait.</li>
<li>I post process the video using code identical to that in AVEditDemo which uses Core Animation.</li>
</ol>
<p>When I play the resultant video using the Camera App, it is rotated 90 degrees and is not longer "portrait" (it is now in landscape) and squashed. (The aspect ratio seems to have been swapped, width -> height & height -> width.</p>
<p>Have spent many hours on this and am at a loss.</p>
<p>The desired result is a movie identical to the captured original. (With an animated overlay eventually).</p>
<p>To see this in action just download and run the AVEditDemo from Apple, turn Title "ON" and export the movie.</p>

Simple PHP. Try to get rid of nested if's
|
<blockquote>
<p><strong>Possible Duplicate:</strong><br>
<a href="http://stackoverflow.com/questions/4106382/compare-multiple-values-in-php">Compare multiple values in PHP</a> </p>
</blockquote>
<p>Will someone help me to find a better way of writing this, please. I feel as if there has to be something better than nested ifs. I have tried searching, but I don't know what I am looking for.</p>
<p>The code says that if the session variable "auth" is not exactly equal to 0, 1, 2, or 3 then redirect to the login page.</p>
<pre><code>if($_SESSION['auth']!=0){
if($_SESSION['auth']!=1){
if($_SESSION['auth']!=2){
if($_SESSION['auth']!=3){
header("location:login.php");
}
}
}
}
</code></pre>
<p>My initial thought was to do something like this.</p>
<pre><code>if($_SESSION['auth']<=0 || $_SESSION['auth']>=3){
header("location:login.php");
}
</code></pre>
<p>But that doesn't account for fractions of the integer value. Which I only want to allow integer values. My next thought was this.</p>
<pre><code>if($_SESSION['auth']!=0 && $_SESSION['auth']!=1 && $_SESSION['auth']!=2 && $_SESSION['auth']!=3){
header("location:login.php")
}
</code></pre>
<p>But this way is not much different than all the nested ifs. Let me know if I am just attempting to fix something that isn't broken. Thank you in advance. A link to the relevant topic (PHP manual preferably) is all I'm looking for, not the solution.</p>

Is there something like a macro in PHP? Or: How to make an own include function?
|
<p>What I want to do is this:</p>
<p>When I write a class and the class instantiates another class, I want to import that class with an require_once. Just the way I do so in Objective-C. But instead of using plain require_once function and messing around with paths and string concatenation, I would prefer something like:</p>
<pre><code>importClass('myclass');
</code></pre>
<p>but I'm afraid that it's impossible to write a function that will include code. If I would do that in the importClass() function, I would include the class code into the implementation block of the function, which of course is nonsense. So what options do I have here?</p>

How to preserve const-ness of typedef'd types
|
<p>Every once in a while I get hung up by this and no one has really been able to give a satisfying answer.</p>
<p>In a (admittedly contrived) example like this...</p>
<pre><code>typedef std::string _str;
class MyClass
{
public:
MyClass(const _str &s) : m_str(s) { }
private:
const _str &m_str;
}
</code></pre>
<p>... Things work pretty much as expected. The member <code>m_str</code> can only be assigned in the constructor initializer list and cannot be reassigned later on, and non-const iterators are unavailable. Okay, then. But if we do this instead...</p>
<pre><code>typedef std::string _str;
typedef std::string &_strref;
class MyClass
{
public:
MyClass(const _strref s) : m_str(s) { }
void test() { m_str.append(std::string("why am I not const?")); }
private:
const _strref m_str;
}
</code></pre>
<p>... The const gets dropped. Non-cost methods may be called on <code>m_str</code> and it may be reassigned, which is misleading considering it has <code>const</code> written next to it.</p>
<ul>
<li>Can the second example be corrected to maintain const-ness?</li>
<li>Where/why does the c++ spec indicate that this is correct behavior?</li>
<li>What do best practices have to say on the matter?</li>
</ul>

How to set configuration parameters using an array table?
|
<p>Following situation: I have an array with some constant values, which represent ranges.<br>
A range is always between two values in the array, e.g.: 10 - 20 = range1<br>
20-30 = range2 and so on...</p>
<pre><code>const int arr[] = {10, 20, 30, 40, 50, 60};
</code></pre>
<p>With a Search function, I search for the number(val) between those ranges in arr[] and return the range index where val was found.<br>
For example: if val = 15 → return value would be 1<br>
if val = 33 → return value would be 3</p>
<pre><code>int Search(const int arr[], int n, int val)
{
int i = 0;
while (i < n) {
if (val > arr[i])
++i;
else
return i;
}
return -1;
}
</code></pre>
<p>OK, this works out so far...</p>
<p>Now following problem:
I have some parameters let's call them x, y, z which are simple integers and they depend on the value of val.
The parameter values for x, y, z I know already before compilation, of course they are different for every range.<br>
How can I now set x, y and z using the range index?
How can I make an array for example with the constant parameter values for x, y, z and set them depending on the returned range index? Or should it be a struct?
How would that look like...?</p>

Can I put a breakpoint in a running Python program that drops to the interactive terminal?
|
<p>I'm not sure if what I'm asking is possible at all, but since python is an interpreter it might be. I'm trying to make changes in an open-source project but because there are no types in python it's difficult to know what the variables have as data and what they do. You can't just look up the documentation on the var's type since you can't be sure what type it is. I want to drop to the terminal so I can quickly examine the types of the variables and what they do by typing help(var) or print(var). I could do this by changing the code and then re-running the program each time but that would be much slower.</p>
<p>Let's say I have a program:</p>
<pre><code>def foo():
a = 5
my_debug_shell()
print a
foo()
</code></pre>
<p>my_debug_shell is the function I'm asking about. It would drop me to the '>>>' shell of the python interpreter where I can type help(a), and it would tell me that a is an integer. Then I type 'a=7', and some 'continue' command, and the program goes on to print 7, not 5, because I changed it.</p>

</blockquote>
<p>I have a <code>std::vector</code> of unique elements of some undetermined size. I want to fetch 20 unique and random elements from this vector. By 'unique' I mean that I do not want to fetch the same index more than once. Currently the way I do this is to call <code>std::random_shuffle</code>. But this requires me to shuffle the entire vector (which may contain over 1000 elements). I don't mind mutating the vector (I prefer not to though, as I won't need to use thread locks), but most important is that I want this to be efficient. I shouldn't be shuffling more than I need to.</p>
<p>Note that I've looked into passing in a partial range to <code>std::random_shuffle</code> but it will only ever shuffle that subset of elements, which would mean that the elements outside of that range never get used!</p>
<p>Help is appreciated. Thank you!</p>
<p>Note: I'm using Visual Studio 2005, so I do not have access to C++11 features and libraries.</p>

Substring go to End of String
|
<p>I am trying to get have one Substring go from the beginning of a string to a certain position and another Substring go from the end of the last position to the end of the string. But I don't know what the end will be. it will be multiple lengths. Is there a way to just go to the end of the string without giving a specific character position, something like below?</p>
<pre><code>StartVariable.Substring(0, 14)
EndVariable.Substring(15, Substring.Length)
</code></pre>
<p>Thanks!</p>

randomizing two lists and maintaining order in python
|
<p>Say I have two simple lists,</p>
<pre><code>a = ['Spears', "Adele", "NDubz", "Nicole", "Cristina"]
b = [1,2,3,4,5]
len(a) == len(b)
</code></pre>
<p>What I would like to do is randomize <code>a</code> and <code>b</code> but maintain the order. So, something like:</p>
<pre><code>a = ["Adele", 'Spears', "Nicole", "Cristina", "NDubz"]
b = [2,1,4,5,3]
</code></pre>
<p>I am aware that I can shuffle one list using:</p>
<pre><code>import random
random.shuffle(a)
</code></pre>
<p>But this just randomizes <code>a</code>, whereas, I would like to randomize <code>a</code>, and maintain the "randomized order" in list <code>b</code>.</p>
<p>Would appreciate any guidance on how this can be achieved.</p>

Get type instance from string in Python
|
<p>So, I need to cast a value to a given type:</p>
<pre><code>if 'int' == type_name:
value = int(value)
elif 'str' == type_name:
value = str(value)
...
</code></pre>
<p>Is there a way to do that generically? E.g.:</p>
<pre><code>type_instance = get_type_instance(type_name)
value = type_instance(value)
</code></pre>
<p>I'm using Python 2.7, but would be interested in a Python 3.X solution as well.</p>
<p><strong>Update:</strong></p>
<p>Here's the solution I'm using:</p>
<pre><code>class Token:
def __init__(self, type_name, value):
self.type = type_name
self.value = __builtins__[type_name](value) # not safe
</code></pre>
<p>This is just a toy parser. <strong>Don't use in production!</strong></p>

Convert an image to Color object which can be added to background of a Layout
|
<p>I am having the following requirement.</p>
<p>1> I have a background image(png) (containing various shades) of color with stripes.</p>
<p>Is there any class which is already available on Android using which I can convert the image to Color object & set on the layout as background color?
Will the ColorMatrix class help ? I want to avoid using the image as background , as with different screen resolutions , even after having separate drawable folders , there can be cases when the background image can get stretched , giving a wrong view .</p>
<p>Kindly provide your inputs/sample code. If my approach is incorrect , kindly provide the correct logic.</p>
<p>Thanks in advance.</p>

How is this "object expected" JavaScript error possible?

<p>Apparently this line of code is triggering "Object expected":</p>
<pre><code>var bPid = (b != null && typeof (b.processId) == "number") ? b.processId : 0;
</code></pre>
<p>Unfortunately I can't step through the code in the debugger since this is an intermittent error that shows up in a Windows SideShow gadget that I'm writing. But, I'd imagine someone should be able to tell me how it's even possible to get object expected given all the checks that I'm doing to attempt to prevent something like that.</p>

Random movement of star on the screen

<p>i want to write a ' * ' to center of the screen and than it can move random to rigth,left,up or down every 100 milisecond.if ' * ' is on the end of row it must be at start of that row and if it is on the end of column it must be at start of that column(and also their reverse scenerio is valid).I wrote thats code but the problem is that i can't delete the old movement(so there are ' * ' for every movement)i solved it to put ' _ ' to its old movement.is there any other solution to make just one ' * ' on screen ?

C++ class conversion possible?
|
<p>I have the following code:</p>
<pre><code>class B {
public:
B(const std::string& str):m_str(str) { }
B(const B& b):m_str(b.m_str) { }
B& operator=(const B& b) { m_str = b.m_str; return *this; }
private:
std::string m_str;
};
main()
{
std::string a = "abc";
B b(a);
}
</code></pre>
<p>class B belongs to the client. I can't change it and I may not even know its specific name ("B" is simply an example); all I know is there's a client class that accepts a std::string for its constructor. Now I want to change the type of "a" in main() from std::string to A, as defined below:</p>
<pre><code>class A {
public:
A(const std::string& str):m_str(str) { }
A(const char *str):m_str(str) { }
A(const A& a):m_str(a.m_str) { }
A& operator=(const A& a) { m_str = a.m_str; return *this; }
private:
std::string m_str;
};
</code></pre>
<p>So now I have a new main():</p>
<pre><code>main()
{
A a = "abc";
B b(a);
}
</code></pre>
<p>This can't compile properly as it is. Is there anything I can do without changing the new main()? I can't change class B, and class A should not reference class B in any way.
Thanks!</p>

So can I just copy-paste my solution file to the new folder that I have checked out code and open it? does it hurt the SVN fille? Is there a more native way for VisualStudio to do that rather than me copy pasting the file?
They look like this in the .sln file:</p>
<pre><code>Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "ucmkaryotypebuilder", "..\UCMKaryotypeBuilder\ucmkaryotypebuilder.csproj", "{77D441DF-5D4D-4F89-BE6D-594C18B46229}"
EndProject

<p>the result is:</p>

getElementById not playing nice with Radio Buttons
|
<p>I am guessing getElementById doesn't work with radio buttons when you want to get the value of it or to find out if it is checked? I say this because I did this:</p>
<pre><code><input id="radio1" type="radio" name="group1" value="h264" checked="checked" />
<input id="radio2" type="radio" name="group1" value="flv" />
</code></pre>
<p>To get the value of the selected one I did this:</p>
<pre><code>function getRadioValue() {
if(document.getElementById('radio1').value=='h264'){
return 'h264';
}
else{
return 'flv';
}
}
</code></pre>
<p>However, firebug keeps telling me:</p>
<pre><code>document.getElementById("radio1") is null
[Break on this error] if(document.getElementById('radio1').checked==true){
</code></pre>
<p>What am I doing wrong?</p>
<p>Thanks all</p>

how can you take an ArrayList of chars and return all those elements from the ArrayList into a String
|
<p>This is the code for trying to answer my question. I'm kind of new with ArrayLists. I used a for loop trying to read every element from the Arraylist and put it in the new String "full" but this won't compile. I need some editing. I don't think this code properly works. I used .add so that I can try adding the elements from the String List to String full. This is what tried to do so far.</p>
<pre><code>public void String() {
ArrayList<Character> StringList = new ArrayList<Character>();
String full;
for(int i = 0; i < arr.length; i++) {
full.add(StringList[i]);
}
return full;
}

Virtual function output?

<p>I was just doing some stuff and wrote this program. I got the following output. I know that function resolution happens at run time while binding of the variable takes place during compile time, but what I could not understand was the first output I got (<code>this->n</code>). Can anyone explain this to me? </p>

set multiple select list options to selected from query

<p>I have a field named 'majors' which contains a string of integers seperated by commas. This field is populated from a multiple select list on insert query using the following variable:</p>
<pre><code>$majors_string = implode(",", $majors);
</code></pre>
<p>Now on the edit page, I want to have those values set the options in the same list. Part of the problem is that the list is generated dynamically using:</p>
<pre><code><select name="majors[]" size="9" multiple="multiple" id="majors">
<?php
$query = mysql_query("SELECT * from major ORDER BY title ASC");
for($i=0;$i<mysql_num_rows($query);$i++) {

<option value="<?php echo $row['major_pk']; ?>"><?php echo $row['title']; ?></option>
<?php

?>

</code></pre>
<p>On the initial query on the edit page, I have:</p>
<pre><code>$query_topic = "SELECT * FROM topic WHERE topic_pk = '$topic_pk'";
$result_topic = mysql_query($query_topic, $connection) or die(mysql_error());
$row_topic = mysql_fetch_assoc($result_topic);
$retrieved_majors = explode(",", $row_topic['majors']);

<p>If I send them the licensed version of the game they won't be able to run it on their phones without buying it. However, if I send them an unlicensed version and someone leaks it then everyone will just be able to get my game for free. What should I do?</p>

Consuming data from WikiNews

<p>I have been scouring the net but I can't seem to find any examples of consuming data from <a href="http://en.wikinews.org/wiki/Main_Page" rel="nofollow">WikiNews</a>. They have an RSS feed with links to individual stories as HTML, but I would like to get the data in a structured format such as XML etc.</p>
<p>By structured format I mean an XML file for each story that has a defined XML schema (XSD) file. See: [http://www.w3schools.com/schema/schema_intro.asp][2]</p>
<p>Has anyone written a program that consumes stories from WikiNews? Do they have a documented API?</p>
<p>I would like to use C# to collect selected stories and store them in SQL Server 2008.</p>

<p>I'm developing my website in struts, hibernate and jsp. I had called a function which is in my DAO page from my action page like this:</p>

Passing string into Onchange

code example which i am trying:</p>

var r1 = '<label style="vertical-align:2px;">Group by: </label>' +
'<select id="pwx_documents_range_groupby" onchange="ravi('+rvalue+');">' +
'<option value="listview" selected="selected">List View</option><option value="notetype">Note Type</option><option value="author">Author View</option>'+
'<option value="cat">Cat</option></select>'
</code></pre>
<p>This is just sample code.. But the question is once drop down change it will call ravi function and throw me the error 'hi' is undefined. If i am passing 0 instead of hi it works great. I am totally surprise why it will not accept the string.</p>
<p>Anybody have any idea that would be great help.</p>

any way to have std::unordered_set<Base>::count(Derived c)?
|
<p>Lets say I have an abstract base class and a derived class with some unique functionality:</p>
<pre><code>class Shape
{
public:
Shape();
};
class Circle : public Shape
{
public:
Circle(int radius) : radius(radius);
int getRadius() { return this->radius; };
private:
int radius;
};
</code></pre>
<p>Now I can put Circle*:s in std::vector and check afterwards if vector has Shape*</p>
<pre><code>std::vector< Circle* > v;
Circle* circle = new Circle(1);
v.push_back(circle);
// ...
Shape* someShape = ...; // I know it's a Circle but the pointer comes from class that only knows about Shapes
for(std::vector< Circle* >::iterator it = v.begin(); it != v.end(); ++it)
{
Circle* c = *it;
if((Shape)c == someShape)
{
// found
}
}
// ...
delete c;
</code></pre>
<p>But I want to use std::unordered_set (applies also to std::unordered_map, std::set, std::map) because it has faster-than-linear find() and count()</p>
<pre><code>std::unordered_set< Circle* > u;
Circle* circle = new Circle(1);
u.insert(circle);
// ...
Shape* someShape = ...; // I know it's a Circle but the pointer comes from class that only knows about Shapes
if(u.count(someShape) == 1)
{
// found
}
</code></pre>
<p>Instead of the obivious I get "undefined function" as there only exists std::unordered_set< Key >::count(Key& k);</p>
<p>Is there any way I can find() or count() from std::unordered_set using base class?</p>

$receivedOffersOnItem[$offerReceived->id] = $offerReceived;
}
}
offersReceivedProcessedByItem[$item->id] = $receivedOffersOnItem;
}
</code></pre>
<p>(for each item a user has, filter through the offersReceived array and add the offer to a new array if it has an equal id, if that makes sense?!).</p>
<p>Here's what I'm trying:</p>
<pre><code>$offersReceivedProcessedByItem = array();
foreach ($this->currentSessionUser->items as $item) {
$receivedOffersOnItem = array_filter($item->offers, function($offer){
return $offer->item->id === $item->id;
});
$offersReceivedProcessedByItem[$item->id] = $receivedOffersOnItem;
}
</code></pre>
<p>But i'm getting that $item is undefined, I expect it's closed scope so I tried passing $item as another argument but then i'm getting 'missing argument 2'.</p>
<p>I tried this using the relational approach built into Fuel but PHP eats too much memory and fails.</p>
<p>Any help? What am I getting wrong?</p>

better way to code recursive if statements
|
<p>I find myself in this position occasionally, and I'm sure there is a better way to do it than I am currently.</p>
<p>In this example, I'm trying to sort a group of times where I have conflicting items. I need to know what times are high-priority,can't be moved, vs low priority, can be moved.
But I'm pretty sure this code is very inefficient. </p>
<pre><code>var holdLowPriorities = [];
for (conflict = 0; conflict < sortedTimes.length - 1; conflict++) {
var firstConflictTimeStart = sortedTimes[conflict][0];
var firstConflictTimeEnd = sortedTimes[conflict][1];
var secondConflictTimeStart = sortedTimes[conflict + 1][0];
var secondConflictTimeEnd = sortedTimes[conflict + 1][1];
if (firstConflictTimeStart < secondConflictTimeEnd &&
firstConflictTimeEnd > secondConflictTimeStart) {
// are either of the conflicts a high priority
var firstContactPriority = sortedTimes[conflict][2];
var secondContactPriority = ortedTimes[conflict + 1][2]
if (firstConflictPriority == 2) {
//this is high priority, can't move
}
if (secondConflictPriority == 2) {
// this is also a priority, but has to move
}
// are either of the conflicts a low priority?
if (firstConflictPriority == 0) {
// this is a low priority so I can adjust the time
} else if (secondConflictPriority == 0) {
// this is a low priority so I can adjust the time
}
}
}
</code></pre>
<p>Unfortunately, I don't even know what to call this type of a problem, and therefore don't know what to look for, though I'm sure the answer isn't overly complicated (I hope not anyway). </p>

Intent to launch marketplace app, show all apps by publisher?
|
<p>Is there a way to get the marketplace app to open to a page showing all your apps? I was hoping this would have done it:</p>
<pre><code> https://market.android.com/developer?pub=My+Company+Name
</code></pre>
<p>but it doesn't. Basic idea is to have a button in my game to take users to a page of other apps I've written.</p>
<p>Thanks</p>

Can't write text into textbox in ASP.NET web app
|
<p>I have an ASP.NET web application.</p>
<p>In the codebehind for the .ascx page (which I embed as below), I attempt to write a string to a textbox in a method like this:</p>
<p>Code for embedding control:</p>
<p>Control ctrl = Page.LoadControl("/RackRecable.ascx");
PlaceHolder1.Controls.Add(ctrl);</p>
<p>Method to make string for inserting into textbox:</p>
<pre><code> string AppendDetails()
{
StringBuilder sb = new StringBuilder();
sb.Append("msg" + " " + textbox1.Text etc etc );
return sb.ToString();
}
</code></pre>
<p>Called as (in codebehind event handler for button click):</p>
<pre><code> this.TextBox4.Text = AppendDetails();
</code></pre>
<p>I call it by using ATextBox.Text = AppendDetails (in the button click event handler). The textbox TextBox4 is in the designer file so I am confused why the text does not get written into this textbox (it is readonly and enabled).</p>
<p>When stepping through, the textbox4 control will successfully show the text I want it to display in quick watch but not in the actual page, it won't.</p>
<p>Any ideas?</p>
<p>Thanks</p>

What's an efficient way to test if a player has clicked on one of many objects in a Java game?
|
<p>This is a basic question, but since I haven't been coding Java for long I'd like to get an opinion from someone with more experience. Let's say I have a game in Java in which there are many objects (on the order of 30) on the screen. The player can click on an object and each object handles a mouse click differently.</p>
<p>My question is: if the player clicks on the game window, what's a good way to test if he clicked one of the objects, and if so, trigger that object's mouse click event handler?</p>
<p>Here's what I've come up with so far: my applet has a mouse listener and it could also have a list of all game objects currently in existence. The applet's event handler could traverse the list of objects and see if the coordinates of the click are inside that object's bounding box through something like <code>gameObject.isInsideBBox(int mouseX, int mouseY)</code>.</p>
<p>This would be simple to set up, but I feel like it would be inefficient. If the number of objects is large then the program would have to traverse the list every time a user clicks. Couldn't this become a performance issue?</p>
<p>One alternative would be to have each object have its own MouseListener and add all the objects to some sort of global container. Would this method be more efficient in terms of performance than the above? One other concern is that these Component and Container objects seem to be defined in Java's Swing library, but I'm not using Swing for any other purposes. I have the feeling that would be a misuse of the library.</p>
<p>Any feedback/comments?</p>
<p>(I'd be interested to know if these methods would port over to Android. I realize that's a different topic, but if you have any insight on that, I'd appreciate if you could let me know.)</p>

Checking strings as valid integers
|
<p>i wan to split a string and then check if every part that i splitted is a number or an identifier this is what i did so far :)</p>
<pre><code>public class splitest {
public void splitfunc() {
String str = "A:25";
String[] temp = null;
temp = str.split(":");
run(temp);
}
public void run(String[] s) {
for (int i = 0; i < s.length; i++) {
if (s[i].equals(" ")) { // <<< checks if the splitted string is a digit ot not??
System.out.println(s[i]+" is a number");
} else
System.out.println(s[i]+" is an Identfier");
}
}
public static void main(String args[]) throws Exception {
splitest ss = new splitest();
ss.splitfunc();
}
}
</code></pre>
<p>is there a way to convert the string into a digit then check or something?</p>
<p>the output should be like this:
this is an identifier
this is a number</p>
