Description |
|---|---|---|
BST_UNCHECKED |
0x0000 |
The initial state. |
BST_CHECKED |
0x0001 |
The button control is checked. |
BST_INDETERMINATE |
0x0002 |
The state is indeterminate (only possible when the button control has three states). |

Remarks
A button control with the BS_3STATE or BS_AUTO3STATE button style creates a check box that has a third state that is named the indeterminate state. The indeterminate state indicates that the check box is neither checked nor unchecked.
Example
CButton myPushButton;
// Create a push button.
myPushButton.Create(_T("My button"), WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON,
CRect(10,10,100,30), pParentWnd, 1);
// Invert the highlight state of the button.
myPushButton.SetState(!(myPushButton.GetState() & 0x0004));
