Re: [platform-swt-dev] How to debug GDI object leak

Thanks Steve.  With that link, I was able to find the updated NT version
of the same article:
http://msdn.microsoft.com/msdnmag/issues/03/01/GDILeaks/default.aspx

Lucky for me it included the compiled
executable.  It looks like PENs.  Opened bug 45640.

Thanks,
Randy Hudson

That's because this (internal) API takes a preallocated GDI object.

I used to use DEBUG Windows 98 to check for leaks but I lost this ability
when switching to XP.  I've used BoundsChecker in the past but it
gave tons of false positives making it hard to find the real problem. This
is what Microsoft suggests http://msdn.microsoft.com/msdnmag/issues/01/03/leaks/default.aspx

Images created with Image.win32_new do not register with SLeak....

It's supposed to be an internal function and it is not supposed
to be used in SWT code, but if you use it, SLeak will not
trace images created by this function....
