Hi;

I've created a property grid control inside a XTDockWindow within a MDI application. The grid recreates its contents every time the user selects a different document type to reflect the available properties. But this behavour is not responible for the below mentioned ACCVIO.

When clicking on the in-place button of a CXTPropertyGridItemColor item type the app crashes inside the OnInplaceBtnDown message handler of the CXTPropertyGridItemColor class. I found out that after calling CColorDialog dlg.DoModal() methode the class members seems to be corrupted. So the m_Grid member of the class points to 0xfdfdfdfd just after the return from DOModal().

First I thought that the app runs out of stack space because the dialog object is created on stack, so I doubled the available stack size by increasing the stack parameters on the linker page of the compiler (VC++ 6.0 SP4). But the result is still the same. In all of the sample apps, everything works fine. I checked my solution to create the grid inside the docking window with similar samples and I can't find the difference!

Does anyone know what I'm doing wrong?

Thanxs in advance

Martin

Hello, Martin

I suppose that you call ResetContent of property grid

in the CView::OnActivateView  that called after dialog become visible.  so item is destroyed after

CColorDialog dlg.DoModal()  method.

You're absolutely right!

I made the mistake to reset the content of the property grid each time the view was activated/deactivated in OnActivateView.

I fixed it and now it works as expected.

Thanks

Martin
