CWnd::OnGetDlgCode

Syntax

afx_msg UINT OnGetDlgCode();

Remarks

Normally, Windows handles all DIRECTION-key and TAB-key input to a CWnd control. When OnGetDlgCode is called, a CWnd control can choose a particular type of input to process itself.

Although the Default and DefWindowProc member functions always return 0 in response to the WM_GETDLGCODE message, the OnGetDlgCode functions for the predefined control classes return a code appropriate for each class.

OnGetDlgCode's returned values are useful only with user-defined dialog controls or standard controls modified by subclassing.

This message-handler member function calls the Default member function. Override this member function in your derived class to handle the WM_GETDLGCODE message.

Return Value

One or more of the following values, indicating which type of input the application processes:
