CWnd::OnSysDeadChar

The framework calls this member function if the CWnd object has the input focus when the OnSysKeyUp or OnSysKeyDown member function is called.

afx_msg void OnSysDeadChar(
   UINT nChar,
   UINT nRepCnt,
   UINT nFlags 
);

Parameters

  • nChar
    Specifies the dead-key character value.

  • nRepCnt
    Specifies the repeat count.

  • nFlags
    Specifies the scan code, key-transition code, previous key state, and context code, as shown in the following list:

备注

This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
