Hi All

I have a VFP7 app running under XP/NT/2K which when running uses more and more memory as time goes by. I suspect its because I am allocating (and re-allocating) some char buffers for various functions I need in a dll which requires parameters by reference.

Nither RELEASE'ing the variable I am passing, the FLUSH command, nor the SYS(1104) function releases memory VFP is using. Furthermore the SYS(3050) does not limit the memory usage as advertised.

However, I do notice that if you minimize the VFP app almost all memory is released except a few hundred kb. If I simulate a minimize using _SCREEN.WindowState = 1 then the same thing happens and memory is released.

Question: does anybody know what internal functions VFP excutes on a minimize event to release the memory buffers? This would be very useful to know since it clearly performs far better than SYS(1104) and the like.

If not is there a way to execute the _SCREEN.WindowState = 1 and then a _SCREEN.WindowState = 2 without the screen flicker :)

TIA
