As described in the subject, I developed an application using VB2005 with .NET framework 2.0 which is required to be upgraded when installing VB2005.

Set it up on an older computer(There is no problem during setup) which is running in XP SP1, it gives error message as follows:

"Selected collating sequence not supported by the operating system." followed by

"There is no row at position 0."

It seems to me the target database was not connected correctly so the data could not be read.

Anybody has the same experience

The problem is the older computer system could not be upgraded until after Christmas.

Why can't you upgrade the system from XP SP1 to XP SP2

Can you provide a sample piece of code that repros what you are seeing in the simplest terms

The biggest issue is not with XP SP1 vs XP SP2. Neither came with .NET Framework 2.0 with it by default, so the machine that you are targeting will need to have the .NET Framework 2.0.

If you are asking specific run time behavior differences between .NET Framework 2.0 on XP SP1 and XP SP2. That would be a question more suited for the .NET Framework General Questions. Let me know if you want me to move this thread to that forum, or you can start a new thread.
