VB.NET Windows application doesn't work very well on Win 98 SE

[Vikas]

I am working on an application that has been developed
using Visual
Basic .net and Visual Studio.net (Framework version 1.0).
The
application works perfectly on Windows 2000/XP.
On windows 98 SE, it's behaviour is totally unpredictable.
There is no
obvious pattern (if there are bugs). Sometimes, the user
cannot log into
it and gets "Illegal Operation" error. Sometimes clicking
on a button
closes the application. None of these problems occur in
Windows 2000 and
XP. And the problems don't always repeat themselves on Win
98. What
could be possibly wrong? Is it the CLR that MS has
provided for Win 98?
Where can I get the support from the Microsoft on this?

Hi,

I don't have problems like that. Is your application accessing a database?
In that case you need to instal MDAC 2.7 or higher. You also may need to
install dotnetfx.exe in addition.

Check MSDN for MDAC (file MDAC_Typ.exe), dotnetfx.exe (also known as
DotNetRedist.exe which just unpacks the dotnetfx.exe) and if you are using
Windows Installer for deployment, you may need to check for bootstrapper
that contains Setup.exe and Setup.ini files needed for deployment.

For MDAC versions go to:
http://msdn.microsoft.com/library/de...dataaccess.asp

Hope it will help

Are you sure your application only uses classes available on Windows 98
machines? Have a look at the documentation for the classes you use in
your application if they will work on Windows 98. You will find this
information at the bottom of their page in the MSDN library.
