One other thing instead of GetDesktopWindow why not AfxGetMainWnd?

Thanks to all for your comments.

I tried to implement it acordingly (in VS6).
It is a regular DLL - but now I added the #defines

#define _AFXDLL
#define _AFXEXT

int16 ShowAdvOptions() {
AFX_MANAGE_STATE(AfxGetStaticModuleState( ));

CIkonAdvOptionsDlg* pMyOptionsDlg = new CIkonAdvOptionsDlg(NULL);
//instead NULL: CWnd::GetDesktopWindow());
pMyOptionsDlg->Create(IDD_IKONADVOPTIONSDLG_DIALOG, NULL);
//instead NULL: CWnd::GetDesktopWindow());
pMyOptionsDlg->DoModal();

return 0;

};

Still I get a crash (I call the function in the DLL from Matlab)

If I leav away the DoModal, nothing (severe) happens.

I also tried to exchange the NULL with CWnd::GetDesktopWindow() - but
with the same result.

Do you have any further suggestions?

Pascal

You are confusing the issue. If you use DoModal, you dont need to call
Create. If you make it modeless, you will need to call Create after
creating the dialog object on the heap(creating it with new) and then
call ShowWindow.

You are mixing the two. Look at Norbert's reply for how to use it as a
modal.

Also, since you are using a Regular DLL(why?), where is your dialog
resource. Your code implies that the dialog resource is sitting in the
same DLL as the code. Is that correct? If not, you will need to use a
different version of AFX_MANAGE_STATE.
