--------------------编程问答-------------------- up --------------------编程问答-------------------- 路过帮顶一下 --------------------编程问答-------------------- godgreat 那样不可以啊
我是要打印窗体上的控件里面的内容啊 --------------------编程问答-------------------- 如果要打印整个窗体
[System.Runtime.InteropServices.DllImport("gdi32.dll")]
public static extern long BitBlt (IntPtr hdcDest, int nXDest, int nYDest, int nWidth, int nHeight, IntPtr hdcSrc, int nXSrc, int nYSrc, int dwRop);
private Bitmap memoryImage;
private void CaptureScreen()
{
Graphics mygraphics = this.CreateGraphics();
Size s = this.Size;
memoryImage = new Bitmap(s.Width, s.Height, mygraphics);
Graphics memoryGraphics = Graphics.FromImage(memoryImage);
IntPtr dc1 = mygraphics.GetHdc();
IntPtr dc2 = memoryGraphics.GetHdc();
BitBlt(dc2, 0, 0, this.ClientRectangle.Width, this.ClientRectangle.Height, dc1, 0, 0, 13369376);
mygraphics.ReleaseHdc(dc1);
memoryGraphics.ReleaseHdc(dc2);
}
private void printDocument1_PrintPage(System.Object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
e.Graphics.DrawImage(memoryImage, 0, 0);
}
private void printButton_Click(System.Object sender, System.EventArgs e)
{
CaptureScreen();
printDocument1.Print();
}
如果要打印内容,我是用RDLC,我用的是.NET2005
这个可以实现打印.不过我正在找直接打印的办法 --------------------编程问答-------------------- 我只能说个思路，太懒不想写代码。
做一个 PrintItem 类，为每个需要打印的控件创建一个 PrintItem，放到集合里，然后打印这个集合。 --------------------编程问答-------------------- mark --------------------编程问答-------------------- http://www.codeproject.com/dotnet/PrintingFormReport.asp --------------------编程问答-------------------- http://www.codeproject.com/dotnet/PrintingFormReport.asp
