MFC static text 设置背景透明失败

[cahnghui3067]

我在VC里写MFC的时候，在类的消息WM_CTLCOLOR中用了下面的代码设置static text控件的背景透明：
if(nCtlColor == CTLCOLOR_STATIC)
{
pDC-> SetBkMode( TRANSPARENT );
}
但是运行的结果是文字背景为基础的灰色，而不是和对话框的背景图一致的颜色，请问有谁遇到过这样的问题吗？有什么解决办法吗？

HBRUSH CZilchDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) { // Call the base class implementation first! Otherwise, it may // undo what we're trying to accomplish here. HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor); // Are we painting the IDC_MYSTATIC control? We can use // CWnd::GetDlgCtrlID() to perform the most efficient test. if (pWnd->GetDlgCtrlID() == IDC_MYSTATIC) { // Set the text color to red pDC->SetTextColor(RGB(255, 0, 0)); // Set the background mode for text to transparent // so background will show thru. pDC->SetBkMode(TRANSPARENT); // Return handle to our CBrush object hbr = m_brush; } return hbr; } 试试用控件ID行不

HBRUSH Cxxx::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
     if(nCtlColor == CTLCOLOR_STATIC)
     {
		 pDC->SetBkMode(TRANSPARENT);
		 //CWnd* pStatic = GetDlgItem(IDC_XXXXX);
		 //if(pWnd->m_hWnd == pStatic->m_hWnd)
		 //{			
		 //	 pDC->SetTextColor ( RGB(0,0,255) );
		 //}

		 return   (HBRUSH)::GetStockObject(NULL_BRUSH);   
     }
     return CxxxParent::OnCtlColor(pDC,   pWnd,   nCtlColor);;
}

需要返回透明画刷 return (HBRUSH)::GetStockObject(NULL_BRUSH);

谢谢了，的确是这样。

}

非常感谢，就是那个reuturn的问题
