An application sends a BM_GETCHECK message to retrieve the check state of a radio button or check box.
BM_GETCHECK wParam = 0; // not used; must be zero lParam = 0; // not used; must be zero
This message has no parameters.
The return value from a button created with the BS_AUTOCHECKBOX, BS_AUTORADIOBUTTON, BS_AUTO3STATE, BS_CHECKBOX, BS_RADIOBUTTON, or BS_3STATE style can be one of the following:
Value |
Meaning |
BST_CHECKED |
Button is checked. |
BST_INDETERMINATE |
Button is grayed, indicating an indeterminate state (applies only if the button has the BS_3STATE or BS_AUTO3STATE style). |
BST_UNCHECKED |
Button is unchecked |
If the button has any other style, the return value is zero.
