Performance testing tools for VB.NET application

[sonu]

Hi all,

I am confused about how to check my application against the performance
issues.
In my application as far as possible whenever I could make out I am
using dispose to release
the handles by the application. But it seems that still even then the
handle count is not
equal to the count which I had when I have opened the form. I am not
able to figure out what's
the exact issue is with my application.

Could somebody tell me the ideal coding practices which I should use
when developing the
application so that I have a managed control over the window handles in
my application.

I am really worried about the increasing handles in my application.

One more issue is with use of win32 api calls. As far as I know use of
win32 api's introduces
unamaged coding practices in .NET application. But is it that it should
not be used.

Actually I am not able to find out equivalent .NET functions which I
can use in this scenarios
which could help me out to build a proper application.

Any reply will be a greate help

Thanks in advance

Are you using a profiler? You should be able to detect any .NET objects that
hanging around in memory.

In .NET 1.x there were Framework bugs that made it hard to avoid leaks, but
I don't know if this is still the case in .NET 2.0.

Sonu,

We are at the border for WinFX instead of Win32. Managed code should handle
both and makes it possible to Microsoft to set this step..

Just my thought,
