#define MM_MENUCHAR 0x003f
Non-mnemonic menu char pressed.
- mp1
- window handle of menu currently displayed
- mp2
- SHORT1FROMMP(mp2)
- character
- SHORT2FROMMP(mp2)
- unused
Returns how PM should deal with this invalid character:
- MRFROM2SHORT(0, 0)
- character is invalid (beep)
- MRFROM2SHORT(0, 1)
- cancel the menu
- MRFROM2SHORT(position, 2)
- select the menu item specified by position
Any other return code means to ignore the character and do nothing. Normally, this message is passed to WinDefWindowProc, which returns 0L.
This message is sent from the menu code to its owner when the WM_CHAR message is being processed, and the alphanumeric key pressed does not match any of the mnemonics in the displayed menu. It allows the application to specify which menu item should be selected in this case.
