我有窗口的形式,但我想在windows窗體打印面板隱藏打印按鈕,這是我的代碼:如何在Windows窗體中打印面板?
private void printDoc_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
System.Drawing.Image image = System.Drawing.Image.FromStream(this.streamToPrint);
int x = e.MarginBounds.X;
int y = e.MarginBounds.Y;
int width = image.Width;
int height = image.Height;
if ((width/e.MarginBounds.Width) > (height/e.MarginBounds.Height))
{
width = e.MarginBounds.Width;
height = image.Height * e.MarginBounds.Width/image.Width;
}
else
{
height = e.MarginBounds.Height;
width = image.Width * e.MarginBounds.Height/image.Height;
}
System.Drawing.Rectangle destRect = new System.Drawing.Rectangle(x, y, width, height);
e.Graphics.DrawImage(image, destRect, 0, 0, image.Width, image.Height, System.Drawing.GraphicsUnit.Pixel);
}
public void StartPrint(Stream streamToPrint, string streamType)
{
this.printDoc.PrintPage += new PrintPageEventHandler(printDoc_PrintPage);
this.streamToPrint = streamToPrint;
this.streamType = streamType;
System.Windows.Forms.PrintDialog PrintDialog1 = new PrintDialog();
PrintDialog1.AllowSomePages = true;
PrintDialog1.ShowHelp = true;
PrintDialog1.Document = printDoc;
DialogResult result = PrintDialog1.ShowDialog();
if (result == DialogResult.OK)
{
printDoc.Print();
//docToPrint.Print();
}
}
private void button_Print_Certificate_Click(object sender, EventArgs e)
{
Graphics g1 = this.CreateGraphics();
Image MyImage = new Bitmap(this.ClientRectangle.Width, this.ClientRectangle.Height, g1);
Graphics g2 = Graphics.FromImage(MyImage);
IntPtr dc1 = g1.GetHdc();
IntPtr dc2 = g2.GetHdc();
BitBlt(dc2, 0, 0, this.ClientRectangle.Width, this.ClientRectangle.Height, dc1, 0, 0, 13369376);
g1.ReleaseHdc(dc1);
g2.ReleaseHdc(dc2);
MyImage.Save(@"D:\PrintPage.jpg", ImageFormat.Jpeg);
FileStream fileStream = new FileStream(@"D:\PrintPage.jpg", FileMode.Open, FileAccess.Read);
StartPrint(fileStream, "Image");
fileStream.Close();
if (System.IO.File.Exists(@"D:\PrintPage.jpg"))
{
System.IO.File.Delete(@"D:\PrintPage.jpg");
}
}
那麼問題是什麼?你在標題中提到的小組是如何相關的?你發佈的代碼與你想要的有什麼不同? –
我想在我的winform中打印面板,但此代碼使用按鈕打印打印所有窗體 – user2717468
嘗試用panel對象替換'button_Print_Certificate_Click'中所有出現的'this'。 –
