Graphics application in CVF 6.6 on a 2 cpu machine.

[los]

Hi,

I use graphic Quickwin routines in my program. I have used it for some years on single CPU machines (XP) without any problems. Now, however I have a 2-CPU machine and experience problems quite often, but not always. When I draw a graph for the first time, all information does not appear in the window. If I then try a second time, I will get an access violation in ntdll.dll when initiating the graph. My application uses multi threads but I dont know if this affects my problem.

Has anyone experienced this type of problems?

Thank you for any tips how to solve.

I remember seeing this in the past. A workaround has generally been to put a call to SLEEPQQ(.5) at the start of the program to give the threads time to initialize.

Hi,

Thank you Steve, it seem to work with SLEEPQQ.

I have put in a delay after opening the window and one after drawing the graphbefore reading a continue key stroke fromthe keyboard.

Started with 50 ms delay at the end but that was not enough. But 500 ms works.

Hi, I has a problem like yours about 2 years ago, CVF 6.6 doesn't support 2 cpu, I upgraded to IVF and the problem missing.
