在横向布局中如何实现VB.NET的打印功能？

本文共计391个文字，预计阅读时间需要2分钟。

我已经设置了一个打印我的数据网格视图内容的打印方法，但它不适用于纵向模式。我想在横向模式下打印它。我有我数据集的代码来填充datagridview。 vbPrivate Sub print_Load(sender As System.Object, e As EventArgs) '填充datagridview的代码End Sub

我已经设法打印我的数据网格视图的内容,但它不适合纵向模式.我想在横向模式下打印它会.

我有我的数据集的代码来填充datagridview.

Private Sub print_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim query As String = "SELECT * FROM TBLusers" Dim DA As New SqlDataAdapter(query, CN) Dim DS As New DataSet CN.Open() DA.Fill(DS, "Users") CN.Close() DataGridView1.DataSource = DS.Tables("Users") 'DataGridView1.DataMember = "Users" End Sub

这是我猜的打印功能？我是从教程中得到的.

Private Sub printDocument1_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage Dim dataGridViewImage As New Bitmap(Me.DataGridView1.Width, Me.DataGridView1.Height) DataGridView1.DrawToBitmap(dataGridViewImage, New Rectangle(0, 0, Me.DataGridView1.Width, Me.DataGridView1.Height)) e.Graphics.DrawImage(dataGridViewImage, 0, 0) End Sub

这是打印预览.

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click PrintPreviewDialog2.Document = PrintDocument1 PrintPreviewDialog2.PrintPreviewControl.Zoom = 1 PrintPreviewDialog2.ShowDialog() End Sub

和印刷品……

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click PrintDocument1.Print() End Sub

我试过了
PrintDocument1.PrinterSettings.DefaultPageSettings.Landscape = True

但似乎没有用？

您正在为打印机设置DefaultPage设置.
尝试为文档本身设置它：

PrintDocument1.DefaultPageSettings.Landscape = True PrintDocument1.Print()
