Question

我正在使用Neodynamic SDK将文档打印到客户端。

我们将打印5份文件。我看到如何打印1个文档或打印所有文档，但有没有办法每个按钮打印1个文档。即button1打印出doc1，button2打印doc2等。

这是我到目前为止所做的事情

  <script runat="server">

        Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs)
            fileone()
            filetwo()

        End Sub

        Public Sub fileone()
            Dim fileToPrint As New PrintFile(Context.Server.MapPath("~/forms/xmlheader.txt"), "xmlheader.txt")
            If (WebClientPrint.ProcessPrintJob(Request)) Then

                'Create a ClientPrintJob
                Dim cpj As New ClientPrintJob()
                'set client printer, for multiple files use DefaultPrinter...
                cpj.ClientPrinter = New DefaultPrinter()
                'set files-printers group by using special formatting!!!
                'Invoice.doc PRINT TO Printer1
                cpj.PrintFile = fileToPrint
                'send it...
                cpj.SendToClient(Response)
            End If
        End Sub
        Public Sub filetwo()
            Dim fileToPrint As New PrintFile(Context.Server.MapPath("~/forms/ How To Recover Office Doc.pdf"), " How To Recover Office Doc.pdf")
            If (WebClientPrint.ProcessPrintJob(Request)) Then

                'Create a ClientPrintJob
                Dim cpj As New ClientPrintJob()
                'set client printer, for multiple files use DefaultPrinter...
                cpj.ClientPrinter = New DefaultPrinter()
                'set files-printers group by using special formatting!!!
                'Invoice.doc PRINT TO Printer1
                cpj.PrintFile = fileToPrint
                'send it...
                cpj.SendToClient(Response)
            End If
        End Sub



        Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
            fileone()
            ScriptManager.RegisterStartupScript(Me, Me.GetType(), "printForm1", "printForm1();", True)
        End Sub

        Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs)
            filetwo()
            ScriptManager.RegisterStartupScript(Me, Me.GetType(), "printForm2", "printForm2();", True)
        End Sub

我想过将filetwo（）变量更改为clientprintjob cpj2 ...

Answer 1

您需要的是创建一个名为PrintDoc（）的函数，该函数接收要作为参数打印的文件的路径。签名应如下所示：

Private Sub PrintDoc(path as String)

End Sub

你只需要这个功能一次，不需要sub fileone（）和sub filetwo（）......直到filefive（）。你只需要这个名为PrintDoc的子程序（路径为字符串）

然后你需要5个按钮，每个按钮都有自己的_Click（）事件，在那个事件处理程序中，你通过每次传递一个不同的参数来调用PrintDoc过程。

希望这有帮助。

祝你好运！

使用不同按钮打印不同文档
