Re: Canvas does not allow drawing

[CStrugling]

Hi programmers,

Do you know how to fix this bug issue "Canvas does not allow drawing". I get this error when I draw to my canvas by moving many times, ie: draw a line many times. Sometimes this will appear and application crash.

I`m using Borland C++ 2006 version. Is this a bug on borland? Im searching from the websites, and there are some links regarding this. I tried their solutions but it seems bug still appear.

Hope you can help to solve my problem.

Hi

It could be that if you are drawing too many times the Canvas is updating while you are trying to draw to it again...

Why not trap the error..put a Sleep(500) if it fails then try again.



Hope this helps!
