如何判断指定按纽是否处于按下状态?

请教如何判断指定的CBUTTON 按纽控件是否处于按下状态? 最好用代码说明. 多谢

[shazhushe]

我在CDIALOG中重载WM_LBUTTONDOWN和WM_LBUTTONUP,在ONLBUTTONDOWN()事件函数中添加如下代码:
{ CButton *P=(CButton *)GetDlgItem(IDC_BUTTON1);
if(p->GetCheck()){
AfxMessageBox("OK");
}
}

怎么执行不到ＩＦ条件中去？　　求教？

if(p->GetCheck()==1){

按下按钮的时候，不会触发dialog的WM_LBUTTONDOWN事件。
可以自己写个类继承CButton，在这个类的WM_LBUTTONDOWN事件处理函数里发消息通知对话框按钮按下

按钮按下时有响应函数的。

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.


Remarks

Retrieves the state of a radio button or check box.
