I am using a Child window within a dock control bar. The child window however is created in a COM dll and the main app creates a CExtControlBar which the com dll uses as a parent for the child dialog it creates.

I have encountered a few problems:

If i have a CEdit control on the child dialog then messages such as ctrl+v do not get processed.
Tabbing around the dialog controls does not work
If I use a DHTML dialog as the child dialog and navigate it to a web page with a edit box on then pressing enter doesnt make a new line (as well as the other problems experienced with a normal dialog).

I have sent some demo projects for the com dll and exe to the support email address.

Thanks in advance.

Dear Chris,

We have modified your projects. First of all, we made the CIPlugInterface control more powerful:

class ATL_NO_VTABLE CIPlugInterface : 
      public CComObjectRootEx<CComSingleThreadModel>,
      public CComCoClass<CIPlugInterface, &CLSID_IPlugInterface>,
      public IDispatchImpl < IIPlugInterface, 
                          &IID_IIPlugInterface, 
                          &LIBID_XPPluginLib, 
                           /*wMajor =*/ 1, 
                           /*wMinor =*/ 0>,
      public IOleInPlaceActiveObjectImpl < CIPlugInterface >
      , public CComControl < CIPlugInterface >
      ,     public IOleControlImpl < CIPlugInterface >
      ,     public IOleObjectImpl < CIPlugInterface >
      ,     public IViewObjectExImpl < CIPlugInterface >
      ,     public IOleInPlaceObjectWindowlessImpl < CIPlugInterface >
      ,     public IQuickActivateImpl < CIPlugInterface >
. . .

It was not possible to avoid this modification. Second, we have created the CMyCompatibleControlBar class in your EXE project and we used it as a type for the CMainFrame::m_wndResizableBarDlg property. This control is now compatible with your improved window-based COM control. It is possible to avoid using CMyCompatibleControlBar, but you should create an improved version of your control using the CWnd::CreateControl() method. The Prof-UIS 2.33 works very well with CWnd-subclassed COM controls.

Finally, we have modified the properties of the dialog template resource in your project: we set up the want return property of the multi-line edit control to true.
