在初始化函數OnInitDialog()中加入:
BOOL CTestDlg::OnInitDialog()
{
CDialog::OnInitDialog();
CBitmap bmp;
bmp.LoadBitmap(IDB_BITMAP2);
m_brBk.CreatePatternBrush(&bmp);
bmp.DeleteObject();
return TRUE; // return TRUE unless you set the focus to a control
}
在打開類向導,找到WM_CTLCOLOR消息,重載得對應函數OnCtlColor(),添加如下:
HBRUSH CTestDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if (pWnd == this)
{
return m_brBk;
}
return hbr;
}
