Re: Crash in BeginPaint running Sams Photofact index, a free VB app

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



That did it.  And yes, the workaround was needed in EndPaint, too;
I tried Mike's patch first, and added the EndPaint workaround myself
before I noticed Dmitry's patch.

The app isn't very functional, but at least it doesn't crash.
I encourage anyone who is working on Visual Basic compatibility
to give http://www.servicesoftware.com/sams/SAMSINDEX.exe a spin.
(And look at all the pretty fixme's :-)

Thanks,
Dan

Attached patch should help a bit.

Protect BeginPaint and EndPaint from lps being NULL.
