I'm maintainig an old MFC application with Visual Studio 2013. Building the application works fine, but I'm unable to use the dialog editor.
When I open a dialog from the resource view, it displays correctly, I can click on the existing items, view their properties, move them etc.
But when I open the toolbox via the View-Toolbox command (Ctrl+Alt+X), all I get is an empty toolbox as displayed below:
- Right click on the toolbar and "Reset Toolbox" doesn't change anything
- Right click and then "Show all" shows an impressive list of tools, among those there is the Dialog Editor, but all items are inactive as shown in the picture below:
On the other hand when I create a new MFC project from scratch, the toolbox containing the dialog items works fine.
Does anybody have an idea what could be wrong? FYI: in the meantime I use Visual Studio 6 (yes) for editing the resources.
