Question about CComboBoxEx

[dssuresh]

Hi ALL, I have overriden the OnSetFocus() for CComboBoxEx control by trapping the WM_SETFOCUS event. This event gets fired only when i tab to that control from another control. This function does not get invoked when i click on the ComboBoxEx control using the mouse. I have some edit controls also on the same dialog and the setfocus event gets fired when i click those controls. Any ideas why the CComboBox is not working? thanks, Suresh

It works for me, In your combo properties, what type you have specified. DropDown, Simple, DropList. Have you tried that? Best, -Alfredo

Alfredo, Thanks a bunch for your response. I have already tried all the three properties, but unfortunately it does not work. Are you using CComboBox or CComboBoxEx?. I tried using CComboBox instead of CComboBox and it does work. Please let me know your comments and thanks again for your help. Suresh

You're right I was using CComboBox not CComboBoxEx. But I am trying to look for another application using CComboBoxEx, let me do some tests and I'll get back to you. Best, Alfredo

Suresh, I just created a CComboBoxEx into my project (Dragging the ctrl into my form), went to class wizard and added the function for the SETFOCUS handle event, placed a MessageBox("Got the Focus", NULL, MB_OK) and it worked as expected. How are you creating your control? Have you tried doing exactly the same thing I just did? Visual C++ 6.0 right? Are you creating a class for you control? I suggest you to try to do the same thing I did in another project to see if it works. Good Luck Best, Alfredo

Alfredo, Thanks a lot for your help on this regard. I got it working by trapping the CBN_SETFOCUS event. Thanks again for your help. LRESULT CConfigCmbFieldWnd::WindowProc( UINT message, WPARAM wParam, LPARAM lParam ) { // Trap the if ( CBN_SETFOCUS == HIWORD( wParam ) ) { CTraceConfigPage* pTraceConfigPage = DYNAMIC_DOWNCAST(CTraceConfigPage, GetParent()); ASSERT( NULL != pTraceConfigPage ); // assign the current control ID pTraceConfigPage->SetFieldCtrlID(m_iFieldCtrlID); } return CComboBoxEx::WindowProc( message, wParam, lParam) ; }
