At one of the customers sites a VO apps with lots of drawing 'hangs' a few
time each day. It cannot be reproduced. The program can be closed with the
closebutton. (So no need to force a close with the taskmanager) . There is
no error message.
I now monitor some recourses , but this does not gives me a clue.
startup: At
hang
Memory(MEMORY_REGISTERAXIT) 402 395
Memory(MEMORY_DYNINFOUSED)/1000 369 357
DynInfoFree()/1000 16407 16418
MemTotal()/10000 356 358
(Memory(MEMORY_WINDOWS_SYSTEMRESOURCES) 80 65-67
At the ‘hang’, all controls are gray. A printscreen at this point says:
“insufficient memory available to bitmap image. Close one or more
applications so that more memory available “
So what memory and how should I monitor to find the cause? Any other
suggestions?

Erik,
In my drawing program, I had a leak where I wasn't releasing the bitmap
handle after I created a jpg. You might check your drawing routine to make
sure that
You clean up your drawing handles after an edit. Mine was a pain to figure
out. I was expecting garbage collection to clean up but because I didn't
release an Ibarra that had a reference to my DIB, it didn't happen.
Hope that this helps.
Regards,
Willie

Hi Willie,
Must be something like that. I now monitor (how to was written in another
thread) the GDI usage and that increases and increases ...
So I'll have to figure out what causes this.
Thanks a lot,
Erik

Erik,
You can use X-Debug.
X-Debug has the possibility to hook almost every lowlevel drawing win32
api function. So, this way you can see which objects are not released
correctly.

GDI Been there done that
Our leak was with cursors, I ended up creating them at programme start
and storing them in global variables, took 4 hours to crash with no GDI
resources.
Use
GetGuiResources(GetCurrentProcess(),GR_GDIOBJECTS)
DEFINE GR_GDIOBJECTS := 0
This returns used GDI objects count.
