AccessViolationException found when using in C#.Net

[dcunited]

Sample Code:

private static AutoItX3Class autoIT = new AutoITXClass();

autoIT.WinExists(locCurTitle, locCurText);

This code works fine if an application meets these criteria, if it does not, it throws the AccessViolationException. The expected result is of course that it would return a 0 meaning it did not find the application. Any ideas what I can do to fix this?

Hi,

Maybe it's not relevant, but just in case.

I encountered lots of access violation exception in some third parties applications (at least one coded in c#) and Autoit scripts of my own on some of my computers running xp sp2.

After a few checks and some googling on the web I found a way to get rid of all these errors. Please take a look at http://support.microsoft.com/kb/918165

Despite it was not listed, removing MS KB908531 fixed all problems for my scripts and other applications.

Hope it will at least give you an idea...
