How do I destroy a CXTDock child window?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic


   
I have created a view window that displays an hmlt page. I took the example from GUI_VisualStudio7. Now after showing the html page for a while I want to display an another kind a view (regular dialog view) in the same window.
I haft to find a way to destroy, detach or disable the SetChild(htmlView) function without destroy the parent window otherwise it will not work correctly.
Can someone help me on this?
In my previewWindow.cpp I have:
---------------

int previewWindow::OnCreate(LPCREATESTRUCT lpCreateStruct) 

{
if (CXTDockWindow::OnCreate(lpCreateStruct) == -1)


return -1;

// Create the html start page

CPropertiesBarHelpFrame* pHelpFrameWnd;
pHelpFrameWnd = NULL;
pHelpFrameWnd =  (CPropertiesBarHelpFrame*)CreateFrameDocView(RUNTIME_CLASS(C PropertiesBarHelpFrame), RUNTIME_CLASS( CPropertiesBarHelpView ) );
SetChild(pHelpFrameWnd);

return 0;
}

	I said hourray! to fast. Now a window warning pop's up saying that "A required resource was unavailable" when the focus is set on that window. Does someone know what extra line of code I should use to resolve this issue?

	After a few hours of research, it seems to me that the pHelpFramWnd child window is still hooked to the parent even after a destroyWindow() of that child. When the focus is activated, the parent window searches for the html page that was destroyed and the bug "A required resource was unavailable" appears. What am I missing?
