The CheckDlgButton function selects (places a check mark next to) or clears (removes a check mark from) a button control, or it changes the state of a three-state button.
hwndDlg
Identifies the dialog box that contains the button.
idButton
Identifies the button to be modified.
uCheck
Specifies the check state of the button. If this parameter is nonzero, CheckDlgButton selects the button; if the parameter is zero, the function clears the button. For a three-state check box, if uCheck is 2, the button is grayed; if uCheck is 1, it is selected; if uCheck is 0, it is cleared.
This function does not return a value.
The CheckDlgButton function sends a BM_SETCHECK message to the specified button control in the given dialog box.
