在VB.NET中编程并有另一个小问题。我有TextBox
使用StreamReader
从txt文件填充。基本上我有一个打印选项,但只能打印TextBox
中显示的内容,如果TextBox
中有更多信息需要滚动,那么不打印(希望这有意义! )。有什么方法可以解决这个问题,所以打印出所有的信息吗?
这是我的代码:
Imports System.Drawing.Printing
Public Class JobList
Private Sub JobList_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim objReader As New System.IO.StreamReader("C:\test\JobLog.txt", True)
txtJL.Text = objReader.ReadToEnd
objReader.Close()
End Sub
Private Sub printText(ByVal sender As System.Object, ByVal ev As PrintPageEventArgs)
Dim font As New Font("Arial", 16, FontStyle.Regular)
ev.Graphics.DrawString(txtJL.Text, font, Brushes.Black, 100, 100)
End Sub
Private Sub btnPrint_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPrint.Click
Dim printDoc As New PrintDocument
AddHandler printDoc.PrintPage, AddressOf Me.printText
printDoc.Print()
End Sub
End Class

How to print from a StreamReader
on MSDN,向下滚动 - 有一个例子。从String
打印可能需要稍加修改,然后您可以将TextBox.Text
传递给它。或者只是使用AS IS并从StreamReader
打印 - 无论如何应该得到相同的结果。
