 Topic: Problem with custom control in docking panePosted: 01 October 2010 at 8:25pm |

I have hit a snag creating a custom control in a docking pane. I converted a dialog that's been used forever in our app into a docking pane. This dialog uses a custom control. The dialog's OnInitDialog() method calls the control's CWnd::CreateEx(). When I run the app and try to open the pane, the pane slides down about 1/10 of its opened height and the opening thread locks at that point. It appears to be in an infinite loop.
Any ideas how to fix this?

Hi;
Did you derive the dialog from CXTResizeDialog? |

Hi Martin,
Yes, I did. I derive all of them from CXTResizeDialog.

One more thing: The CWnd::CreateEx() inside the derived class returns 0. I tried breaking on that and single stepping through the bowels of MFC but that didn't reveal anything obvious.
I'm still wondering if there is a thread issue. Has anyone reading this created a custom control dynamically inside a dialog based CDocking Pane?

Maybe you need register window class for this custom window. or something like that.
Difficult to answer without debugging... try to isolate problem with our sample and attach it.
