BN_CLICKED Overview  Group

The BN_CLICKED notification message is sent when the user clicks a button. The parent window of the button receives this notification message through the WM_COMMAND message. Unlike the other button notification messages, this message is intended for applications written for any version of Windows.

BN_CLICKED 

idButton = (int) LOWORD(wParam);    // identifier of button 

hwndButton = (HWND) lParam;         // handle of button 

 

Remarks

A disabled button does not send a BN_CLICKED notification message to its parent window.
