MFC中如何使static控件背景透明

1. 在对话框的头文件中加入

afx_msg HBRUSH OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor);

2. 在对话框的cpp文件中加入

1 BEGIN_MESSAGE_MAP(CtransparentDlg, CDialog)

2 ON_WM_CTLCOLOR()

3 //}}AFX_MSG_MAP

4 END_MESSAGE_MAP()

5

6 HBRUSH CtransparentDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)

7 {

8 HBRUSH hBrush = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

9

10 if(nCtlColor == CTLCOLOR_STATIC)

11 {

12 pDC->SetBkMode(TRANSPARENT);

13 return (HBRUSH)::GetStockObject(NULL_BRUSH);

14 }

15 return hBrush;

16 }
