【问题描述】：

我正在使用 VB .NET 编程，我想在横向模式下打印我的WinFormsApplication，因为纵向模式不适合它。

我已将横向模式设置为 true。你可以参考下面的代码：

    Private Sub PrintAll_Click(ByVal sender As Object, ByVal e As System.EventArgs) 
    Handles PrintAll.Click
    PrintForm1.Form = Me
    PrintDocument1.DefaultPageSettings.Landscape = True
    PrintForm1.Print(Me, PowerPacks.Printing.PrintForm.PrintOption.FullWindow)
    PrintDialog1.ShowDialog()
    End Sub

结果如下截图所示 http://s335.photobucket.com/user/blakeex/media/notcomplete.png.html 谁能分享一些提示或指南？

【参考方案1】：

to print the complete client area of a scrollable form, even if the form has been resized.

试试PrintForm1.Print(Me, PowerPacks.Printing.PrintForm.PrintOption.Scrollable)

这是另一种打印屏幕上可以查看的表单部分的方法：

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
    CaptureScreen()
    PrintDocument1.DefaultPageSettings.Landscape = True
    PrintDocument1.DefaultPageSettings.Margins = New Printing.Margins(0, 0, 0, 0)
    PrintDocument1.Print()
End Sub
Dim memoryImage As Bitmap
Private Sub CaptureScreen()
    Dim myGraphics As Graphics = Me.CreateGraphics()
    Dim s As Size = Me.Size
    memoryImage = New Bitmap(s.Width, s.Height, myGraphics)
    Dim memoryGraphics As Graphics = Graphics.FromImage(memoryImage)
    memoryGraphics.CopyFromScreen(Me.Location.X, Me.Location.Y, 0, 0, s)
End Sub
Private Sub printDocument1_PrintPage(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
    Dim pagerec As New RectangleF(e.PageSettings.PrintableArea.X, e.PageSettings.PrintableArea.Y, e.PageSettings.PrintableArea.Height, e.PageSettings.PrintableArea.Width)
    e.Graphics.DrawImage(memoryImage, pagerec, New Rectangle(Me.Location, Me.Size), GraphicsUnit.Pixel)
End Sub

【讨论】：

亲爱的@tinstaafl 和其他尊敬的成员，我已经尝试过你上面的方法。它无法正常工作，如下面的截图网站所示：[s335.photobucket.com/user/blakeex/media/notcomplete-1.png.html]您能否提出替代方案或我错过了一步？

我添加了替代答案。
