1. Public Class myPrinter
   
2.    Friend TextToBePrinted As String
   
3.    Public Sub prt(ByVal text As String)
   
4.       TextToBePrinted = text
   
5.       Dim prn As New Printing.PrintDocument
   
6.       Using (prn)
   
7.          prn.PrinterSettings.PrinterName = "PrinterName"
   
8.          AddHandler prn.PrintPage,
   
9.             AddressOf Me.PrintPageHandler
   
10.          prn.Print()
    
11.          RemoveHandler prn.PrintPage,
    
12.             AddressOf Me.PrintPageHandler
    
13.       End Using
    
14.    End Sub
    
15.    Private Sub PrintPageHandler(ByVal sender As Object, ByVal args As Printing.PrintPageEventArgs)
    
16.       Dim myFont As New Font("Microsoft San Serif", 10)
    
17.          args.Graphics.DrawString(TextToBePrinted, New Font(myFont, FontStyle.Regular), Brushes.Black, 50, 50)
    
18.    End Sub
    
19. End Class

複製代碼

想請問我應該如何才能把
prn.PrinterSettings.PrinterName = "PrinterName"
改成
prn.PrinterSettings.PrinterName = TextBox1.Text
常試了改但都是錯誤未宣告?

回復 1# 司徒


    試試先把textbox1.text 宣告成string 看看
