CButton::GetState
UINT GetState( ) const;

Return Value

Specifies the current state of the button control. You can use the following masks against the return value to extract information about the state:

Mask Meaning
0x0003 Specifies the check state (radio buttons and check boxes only). A 0 indicates the button is unchecked. A 1 indicates the button is checked. A radio button is checked when it contains a bullet (). A check box is checked when it contains an X. A 2 indicates the check state is indeterminate (three-state check boxes only). The state of a three-state check box is indeterminate when it contains a halftone pattern.
0x0004 Specifies the highlight state. A nonzero value indicates that the button is highlighted. A button is highlighted when the user clicks and holds the left mouse button. The highlighting is removed when the user releases the mouse button.
0x0008 Specifies the focus state. A nonzero value indicates that the button has the focus.



CButton::SetCheck
void SetCheck( int nCheck );

Parameters

nCheck

Specifies the check state. This parameter can be one of the following:

Value Meaning
0 Set the button state to unchecked.
1 Set the button state to checked.
2 Set the button state to indeterminate. This value can be used only if the button has the BS_3STATE or BS_AUTO3STATE style.

int GetCheck( ) const;
Value Meaning
0 Button state is unchecked.
1 Button state is checked.
2 Button state is indeterminate (applies only if the button has the BS_3STATE or BS_AUTO3STATE style).
If the button has any other style, the return value is 0.

可是我怎么取得这个CButton的指针呢?

[fly2skylee]

我只能利用GetDlgItem(IDC_RADIO_PROXY)取到一个CWnd,不是CButton.

[xt_jat]

CButton* pButton=(CButton*)GetDlgItem(IDC_RADIO1);
pButton->SetCheck(1);
