目的是在MFC下png实现不规则窗体上绘制文字
文字绘制如下：
void CLoginDialog::DrawUI()
{
HDC hDC=::GetDC(m_hWnd);
HDC hMemDC=::CreateCompatibleDC(hDC);

BITMAPINFO bitmapinfo;
bitmapinfo.bmiHeader.biSize = sizeof(BITMAPINFOHEADER);
bitmapinfo.bmiHeader.biBitCount = 32;
bitmapinfo.bmiHeader.biHeight = m_pSrcImage->GetHeight();
bitmapinfo.bmiHeader.biWidth = m_pSrcImage->GetWidth();
bitmapinfo.bmiHeader.biPlanes = 1;
bitmapinfo.bmiHeader.biCompression=BI_RGB;
bitmapinfo.bmiHeader.biXPelsPerMeter=0;
bitmapinfo.bmiHeader.biYPelsPerMeter=0;
bitmapinfo.bmiHeader.biClrUsed=0;
bitmapinfo.bmiHeader.biClrImportant=0;
bitmapinfo.bmiHeader.biSizeImage = bitmapinfo.bmiHeader.biWidth * bitmapinfo.bmiHeader.biHeight * bitmapinfo.bmiHeader.biBitCount / 8;

HBITMAP hBitmap=::CreateDIBSection (hMemDC,&bitmapinfo, 0,NULL, 0, 0);
HBITMAP hOldBitmap = (HBITMAP)::SelectObject (hMemDC,hBitmap);

//画出各个界面元素----------------------
Graphics g(hMemDC);
g.DrawImage(m_pSrcImage,RectF(0,0,m_pSrcImage->GetWidth(),m_pSrcImage->GetHeight()),0,0,m_pSrcImage->GetWidth(),m_pSrcImage->GetHeight(),UnitPixel,NULL,NULL,NULL);

FontFamily* fontFamily = new FontFamily(L"微软雅黑");//选择一种字体

Gdiplus::SolidBrush* company_brush = new Gdiplus::SolidBrush(Color(255,24,120,197));
Gdiplus::Font* company_font = new Gdiplus::Font(fontFamily,11,FontStyleRegular,UnitPoint);
g.DrawString(L"Hello Word！",-1,company_font,PointF(335,346),company_brush);

delete fontFamily;
delete company_brush;
delete company_font;

//设置透明窗口-------------------------------------------------
CPoint DestPt(0,0);
CSize psize(m_pSrcImage->GetWidth(),m_pSrcImage->GetHeight());
BLENDFUNCTION blendFunc32bpp;
blendFunc32bpp.AlphaFormat = AC_SRC_ALPHA;
blendFunc32bpp.BlendFlags = 0;
blendFunc32bpp.BlendOp = AC_SRC_OVER;
blendFunc32bpp.SourceConstantAlpha = 255;
::UpdateLayeredWindow(m_hWnd,hDC,NULL,&psize,hMemDC,&DestPt,0,&blendFunc32bpp,ULW_ALPHA);
//释放资源-------------------------------------------------
::SelectObject (hMemDC,hOldBitmap);
::DeleteObject(hBitmap);
::DeleteDC(hMemDC);
::ReleaseDC(m_hWnd,hDC);
}

问题解决了，是因为我用了png透明背景结果画在上面的字被背景透过去了，解决问题的方法是：GraphicsPath path; path.AddString; g->FillPath( brush, path); 就可以了。感谢捧场 分数给你了。
