And when the MFC dll unloads, it does a memory leak check and incorrectly reports that all the VTK objects still left are leaks. <BR><BR>You can overcome this by updating VTK to the CVS version and rebuilding VTK with VTK_USE_GUISUPPORT and VTK_USE_MFC turned on. I recently added flags to the CMakeLists to eliminate these false memory leak reports. <BR><BR>Alternatively, you can use the /DELAYLOAD linker flag to force the VTK dlls to be loaded after the MFC dll
and then they will also be unloaded prior to the MFC dll. Then any leak reports that you see will be for real... (This is what I added in CVS VTK to fix the problem.) <BR><BR>HTH,<BR>David<BR><BR></SPAN></FONT></P>

<P class=MsoNormal><FONT face="Times New Roman" size=3><SPAN lang=EN-US style="FONT-SIZE: 12pt">Hello all,<BR><BR>I finally got my M$ VC project working, using vtkMFCWindow. In this program i read some geometrical data from disk using my own readerfunction. I then display it using vtkMFCWindow. That all works fine, until i close the program and clean up the memory. At the end of program i get a message that memory leaks are detected. The problem is, that i really have no clue where they are from. When i look at the data dumped by VC, i find references to all kinds of objects i never have used. Can anybody tell me what i am doing wrong, or give me any other clues? I have build my program mostly using the examples given for vtkMFCWindow, however, also these examples give me the same problems. <BR><BR>Thanking in advance,<BR><BR>Han<BR><BR>Send instant messages to your online friends <A href="http://uk.messenger.yahoo.com/" target=_blank
