This message returns the highlighting state of a button control.
Syntax
param1
ULONG ulReserved; /* Reserved value, should be 0. */
param2
ULONG ulReserved; /* Reserved value, should be 0. */
Parameters
- ulReserved (ULONG) - input
- Reserved value, should be 0.
- ulReserved (ULONG) - input
- Reserved value, should be 0.
Returns
- rc (BOOL) - returns
- Highlight indicator.
- TRUE: The button control is displayed in highlighted state.
- FALSE: The button control is displayed in unhighlighted state.
Remarks
The button control responds to this message, if it has a style of BS_PUSHBUTTON, by setting rc as appropriate.
If the button has any other style, the button control takes no action other than to set rc to FALSE.
Default Processing
The default window procedure does not expect to receive this message and therefore takes no action on it, except to set rc to the default value of FALSE.
