Unknown application bugs

[Stephan]

Dear All,

I have recently implemented a program in my workplace which is meant
to be a client-server desktop application. Among 5 of my users, 4 of
them are running on Windows XP and 1 of them is running on Windows
Vista.

By the way, I am developing with VB.NET is VS2003 and the database is
SQL2005 Express.

Here is the odd thing, 3 of the users are not having problems to view
on the line details created by each others, however, the other 2 users
could not retrieve the line records created by the other 3 users
through the system although we could see clearly that the records are
actually created in the database, and vice versa.

Well, as a matter of fact, all the five users are mapping to the same
location for running the application and .NET security policies has
been created on individual client PCs. I just have no ideas how come
the above incident could happen.

Any helps offered is very much appreciated.

By the way, the user running on Windows Vista could not run the
Crystal Report correctly. I would assume it might the OS which has
caused the problem, does anyone having any workaround for that one.

Thanks again!

Well, one thing is for sure. You compiled that solution on the XP platform
to run on the XP platform I would suspect. That doesn't mean you can install
the solution on Vista without some possible code modification, compilation
and testing on the Vista platform so that it works on Vista. The same would
hold true for the Crystal Report too I would think, it it was developed on
an XP machine and deployed or used by a Vista machine.

Sorry that I might make a mistake initially and has replied to the
author instead of replying to the group. Anyway, I would like to
thank Mr. Arnold for trying to help me out.

However, seems that I never make the whole problem clear enough....

I agreed with Mr. Arnold that my application might not be fully
compatible to the 1 unit Vista machine. However, my problem is that
how come the other unit of XP machine would have the problem to access
all the records created by the other 3 users. Furthermore, the XP
machine is the only one who can access records generated by the Vista
machine...

This is first time happening to me after quite some while I have
programmed with the VS 2003. Any helps or guidelines is very much
appreciated.

Thank you.
