请问如何修改单文档窗体的背景色？我指的是窗体的边框？

[zhucde]

BOOL CAaView::OnEraseBkgnd(CDC* pDC)

{

CBrush Brush (RGB (128 , 0 , 128) );//你的颜色

CBrush* pOldBrush = pDC->SelectObject(&Brush);

CRect rcClip;

pDC->GetClipBox(&rcClip);

pDC-> PatBlt (rcClip.left , rcClip.top , rcClip.Width ( ) , rcClip.Height( ) , PATCOPY );

pDC->SelectObject (pOldBrush );

return TRUE;

}

先在MainFrm里用class wizard添加WM_ERASEBKGND消息
然后如上编写OnEraseBkgnd()

void CMainFrame::OnNcPaint()
{
// TODO: Add your message handler code here
CRect rc;
GetWindowRect(&rc);
CWindowDC dc(this);
dc.FillSolidRect(rc, RGB(255,0,0));

// Do not call CFrameWnd::OnNcPaint() for painting messages
}

把非可户区都画没了，

创建一个基于CWnd的新窗口类，我们称之为CMDIClient，
在CMDIFrameWnd的继承类中增加一个CMDIClient成员
#include "MDIClient.h"
class CMainFrame:public CMDIFrameWnd
{

protected:
CMDIClient m_wndMDIClient;
}
重载CMDIFrameWnd:OnCreateClient()函数
BOOL CMainFrame：：OnCreateClient(LPCREATESTRUCT lpcs,CCreateContext* pContext)
{
if(CMDIFrameWnd::OnCreateClient(lpcs,pContext))
{
m_wndMDIClinet.SubclassWindow(m_hWndMDIClient.GetSafeHwnd());
return true;
}
else
return false;
}
CMDIClient增加WM_ERASEBKGND 的消息处理函数以画上你想要的背景

对于单文档一样

看看WM_NCPAIT,也许对你有帮助

[lzwcom]

SetClassLong(pView->GetSafeHwnd(),GCL_HBRBACKGROUND,(HBRUSH)CBrush(RGB(x,x,x)))

窗体的边框->指什么？说清楚点
