However, the approach you suggest, that's exactly what i have done. In fact it also happens when i place both the new and the delete command directly after eachother, the same thing happens... I might try a rebuild...<br><br>Thanks anyway<br><br><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;">----- Original Message ----<br>From: John Platt <jcplatt@dsl.pipex.com><br>To: echinococcus Multilocularis <lintworm2@yahoo.co.uk><br>Cc: vtkusers@vtk.org<br>Sent: Monday, 16 October, 2006 12:27:05 AM<br>Subject: RE: [vtkusers] vtkMFCWindow: new and delete problems<br><br>

are using the document view architecture, you would normally let the document
create the view through an appropriate document template. SDI & MDI
projects will do this automatically for you. If you look at a typical CView
derived class you will see that the constructor is protected preventing the
kind of operation you are attempting.</span></font></p>

I have restarted working with vtk, this time under windows, M$ VC++ 6.0. I have
vtk 5.0.2 installed, built in the release with symbols mode, on a windows 2000
machine. I want to use the MFC functionalities, and thus i looked into the
examples on MFC. I have started my own project and use the example to find the
nesecary steps.<br>
<br>
So far so good. However, when want to create a vtkMFCWindow in debug-mode, and
delete it later on, so like this:<br>
<br>
m_pMFCWindow = new
vtkMFCWindow(this->GetDlgItem(DISPLAYFRAME));<br>
delete m_pMFCWindow;<br>
<br>
I get a dialog telling me that a debug assertion failed. specifically it tells
me that it stops on:<br>
pHead->nBlockUsed == nBlockUsed<br>
<br>
Furthermore i get a warning:<br>
Warning: calling DestroyWindow in CWnd::~CWnd; OnDestroy or
PostNcDestroy in derived class will not be called.<br>
<br>
Again, all of this is only in debug mode. I know that i link the vtk library in
release mode w/ symbols on my program, can that be the problem? When i run my
program in Release mode, obviously i don't get the debug assertion failed
dialog. <br>
<br>
How do you create and destroy an object of the type vtkMFCWindow in a correct
way?<br>
<br>
TIA!<br>
<br>
Han</span></font></p>
