Problem loading .xrc file

Hi,

 

I've been taking inspiration from the XRC sample, particularly the code for
derived classes, but get the following:

 

wxWidgets Debug Alert

A debugging check in this application has failed.

C:\Users\Tim\p\wxWidgets\src\msw\window.cpp(1293): assert "!m_oldWndProc"
failed in wxWindow::SubclassWin(): subclassing window twice? 

 

When my code executes:

 

wxXmlResource::Get()->LoadDialog(this, parent, "myDlg");

 

within the constructor of my derived dialog.

 

Googling this message and some variations on it didn't give me any hits to
help me understand the issue.

 

I'd be grateful for any advice as to how to tackle this.

 

Best wishes.

 

Tim
