An application sends a ZGM_ENABLETRANSPARENTHIGHLIGHTING message to enable or disable the grid using transparent highlighting. Transparent highlighting enables the user to see cell background and foreground colors when the row is highlighted due to it being the cursor row, or because an area has been selected for the clipboard.
ZGM_ENABLETRANSPARENTHIGHLIGHTING wParam = (WPARAM) (BOOL) fEnable; //enable flag lParam = 0; //not used; must be zero
This message does not return a value.
Transparent highlighting is enabled (TRUE) by default.
