The IsDlgButtonChecked function determines whether a button control has a check mark next to it or whether a three-state button control is grayed, checked, or neither.

Syntax

UINT IsDlgButtonChecked(          HWND hDlg,
    int nIDButton
);
Parameters

hDlg
[in] Handle to the dialog box that contains the button control.
nIDButton
[in] Specifies the identifier of the button control.
Return Value

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.

If the button has any other style, the return value is zero.

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 cleared

Remarks

The IsDlgButtonChecked function sends a BM_GETCHECK message to the specified button control.

For an example, see the section titled "Creating a Modeless Dialog Box" in Using Dialog Boxes.
