Greetings everyone! I am currently trying to create an application using an
offscreen buffer. I have a great example but it is for VB5/6 and I have
VB.NET. I have not been able to successfully upgrade the code entirely. I
used the converter build into .NET to convert it but there were some
functions that were not upgraded for .NET. The CreateFromPicture function in
the pcMemDV class I can not get to work. The link to the sample I'm using
is:

e_API_Drawing/article.asp


I hope that someone can help me figure this out. Thanks people!

Hi,

           You can use setstyle to double buffer a form.
