"text": "Bueno, este es el final de este capitulo de la trilogía \"ADO y yo\" !\n\nEl asunto esta solucionado. Son tantas las consideraciones y aprendizajes con esto que me paso, que creo que estaré escribiendo algo mas amplio en mi recién abierto blog. Intentaré resumir aquí algunos puntos importantes para los \"foronautas\":\n\n- Despues de buscar mucho entre las opciones para hacer el OPEN en el RS y en la conexion, confirmo que las mejores son las que aparecen en el ejemplo de JLC. \n\n- El asunto estaba en la forma de \"grabar\" el registro en el recordset, que para los fines de la clase ADORS se trata de errores cometidos por mi en el método SAVE(). El grabar en el recordset es uno de los aspectos mas delicados que he encontrado en ADO.\n\n- El mensaje que aparecia era consecuencia de que el RS se \"cerraba\" cuando se hacia una sustitucion que no le gustaba. Mucha luz me trajo a esto el nuevo amigo Fernando Sandoval, cuando me invitó a verificar el tipo de datos que quiero \"grabar\" y el tipo de datos de la columna que quiero que los acepte.\n\n- El problema se concentraba en los campos tipo fecha. Intentaba escribir una fecha en un campo que el ADO lo interpretó como de tipo \"indefinido\". Lo descubrí haciendo VALTYPE( ::oRs:Fields(\"Fecha\"):value ) sobre una fecha en blanco, pues me devolvía \"U\", mientras que cuando el registro tenía una fecha correcta, me devolvía \"D\". Fue entonces que, por sugerencia de FS evité realizar esta sustitución. Aun me falta probar un poco mas con este caso, pero ya está controlado.\n\n- La otra cosa, fue la pregunta clave: \"¿UPDATE o no UPDATE?\".... pues cuando el registro no ha sido cambiado, no debe hacerse. JLC me sugirió en otra parte del foro una manera de realizarlo, pero no me funcionó, así que lo implementé localmente dentro del método SAVE(), y funciona perfectamente.\n\nEstaré probando otras cosas durante la Semana Santa:\n\n- manejo de campos MEMO (BLOB?, TEXT?)\n- Generacion de reportes\n- manejo de ADO por internet, etc.\n\nAsi que por ahora, este capítulo lo considero cerrado. Estaré también publicando las clases modificadas de JLC en mi blog ([url:27i3ejgs]http://mangucybernetico.blogspot.com/[/url:27i3ejgs]) para los que estén interesados, mas un ejemplo realizado por mi para demostrarme a mi mismo la potencia maravillosa del uso de ADO en todo esto.\n\nGracias a todos, en especial a JLC y FS por su paciencia, y sera hasta otro capítulo.\n\n.... Y LA SAGA CONTINUA !!!!",

Now, go to the server and drill to the share and the app and try to run it .. and that is where it breaks.\n\nThere is a a definite Server 2003 process that is intefearing with the ADO connection to the SQL server .. which is off site by the way.\n\nSo I am really looking for a silver bullet that will allow the application to run from the server console. We have over 5000 people in the Agency and this application is the Time and Reporting system.. Many of the folks tele-commute and access the program from Citrix .. thus bringing this problem to the forefront.\n\nThere has to be something in the Server that is breaking the connection .. just don't know what ..\n\nRick Lipkin",

"text": "Rene\n\nAccording to the doccumentation I found :\n\n(1)adOpenKeyset: A static snap-shot of the primary key values of the records that match your search criteria are put into the recordset. As you scroll backwards and forwards, the primary key value in the recordset is used to fetch the current data for that record from the database. This cursor thus allows you to see updates to the data made by other users, but it doesn't let you see new records that have been added by other users (because the primary key values for those records are not in your recordset).\n\n(2)adOpenDynamic: A dynamic snapshot of the database is maintained by OLEDB/ADO. All changes by other users to the underlying database are visible. Obviously this is the most sophisticated cursor, and thus is usually the most expensive. Because the data in the recordset is dynamic,\n attributes like AbsolutePosition and AbsolutePage can not be set. The adOpenDynamic cursor is not supported by the Jet OLEDB Provider.\n\n\nAbsolutePosition I need for the skipper in the listbox .. that is why I chose OpenKeyset .. I have not tried OpenDynamic .. I can easily try it .. I did find a Resync method which seems to be my answer ...

"text": "I work extensively with very large applications ADO and Oracle. My experience with MSSQL is limitted to smaller applications. Resync generally works even when the other users update the same row but occassionally fails. Better we keep in mind how Resync command internally works:\n\nRecordSet object has Properities collection.\noRs:Properties(\"Resync Command\"):Value is what ADO internally uses to retrieve the values of the current row. This value can be set by our program but i am not able to change this property through xharbour. (works in vbasic)\n\nADO has to know the primary key or some unique id of the row to internally construct this command. For example a table has two columns \"custid\", \"custname\" with custid as primary key and if ado can know this, it will internelly construct the resync command as \"select * from customers where custid = ?\" and calls this command with custid as the parameter each time it refreshes. For oracle it uses rowid instead of primary key unless we configure ado differently. This has its own side effects.\n\nThis should give you some idea about the limiations of Resync command.\n\nSo we can use Resync, keeping in mind that it can fail at times and for some recordsets. Solution is to programitically assign right values to the two properties oRs:Properties(\"Root Table\") and oRs:Properties(\"Resync Command\")",
