c# 绘图设备和.net运行库的重绘节点

c#有时候需要给tabcontrol特殊的处理和重绘，例如在tabpages标签页的标题上进行绘制等效果。

c# 代码：

rectangle myrect=this.forms.gettabrect(e.index);

e.graphics.drawstring(this.form1.tabpages[e.index].text,this.font,systembrushes.Menutext,myTabRect.X+4,myTabRect.Y+4);

using (Pen p = new Pen(Color.White))
{
myTabRect.Offset(40,2);
myTabRect.Width = CLOSE_SIZE;
myTabRect.Height = CLOSE_SIZE;
e.Graphics.DrawRectangle(p, myTabRect);
}

Color recColor = e.State == DrawItemState.Selected ? Color.Pink : Color.Wheat;
using (Brush b = new SolidBrush(recColor))
{
e.Graphics.FillRectangle(b, myTabRect);
}

c++代码：

pBitmap->LoadBitmap(IDB_TOP);
pOldBitmap=(CBitmap*)pDisplayMemDC->SelectObject(pBitmap);
pBitmap->GetBitmap(&BmpInfo);
while(DrawPonit.x<= m_rtButtMin.left-66)
{
pDC->BitBlt(DrawPonit.x, DrawPonit.y, BmpInfo.bmWidth, BmpInfo.bmHeight, pDisplayMemDC, 0, 0, SRCCOPY);
DrawPonit.x = DrawPonit.x + BmpInfo.bmWidth;
}
pDisplayMemDC->SelectObject(pOldBitmap);
pBitmap->DeleteObject();
pBitmap->LoadBitmap(IDB_TITLE_RIGHT);
pOldBitmap=(CBitmap*)pDisplayMemDC->SelectObject(pBitmap);
pBitmap->GetBitmap(&BmpInfo);
pDC->BitBlt(DrawPonit.x, DrawPonit.y, BmpInfo.bmWidth, BmpInfo.bmHeight, pDisplayMemDC, 0, 0, SRCCOPY);

pDisplayMemDC->SelectObject(pOldBitmap);
pBitmap->DeleteObject();
