An application sends a ZGM_CLEARMARKONSELECT message to enable or disable the ZeeGrid behavior of clearing a marked cell when the cursor is placed on it. Cells have a MARK attribute that is set by the search function. This is normally set or cleared by the user in the toolbar search function.
ZGM_CLEARMARKONSELECT
wParam = (WPARAM) (BOOL) fEnable; //enable flag
lParam = 0; //not used; must be zero
This message does not return a value.
