问题描述

我有一个客户端，谁正在运行Windows 2008 Server 64位。他正在运行我们的软件，它有一个内置的水晶报表查看器功能。

打印对话框不会工作，无论什么。它工作在我们的32位框，我们验证了。我在我们的64位盒子上验证了它，并且打印对话框也没有打开。我在网上做了一些研究。一个建议是设置m_printDlg.UseEXDialog = True。我试过，但是DID不工作...

我现在很沮丧。有没有人遇到类似的问题？

<$ c如果是，请告诉我。

如果m_printDlg不为空那么
m_printDlg = New PrintDialog
如果

m_printDlg.PrinterSettings = ReportEngine.GetPrinterSettings（objRpt）
m_printDlg.UseEXDialog = True

解决方案

尝试编译您的应用程序以定位任何或目标x64已经任何），看看是否有任何效果。

I have a client, who is running Windows 2008 Server 64 bit. He is running our software, it has a built in crystal report viewer functionality.

The print dialogue just wouldn't work no matter what. It worked on our 32 bit box and we verified it. I verified it on our 64 bit box, and the print dialogue didn't open either. I did some research online. And one suggestion is to set m_printDlg.UseEXDialog = True. I tried that, but that DID NOT WORK EITHER...

I am kind of frustrated now. Has anyone encountered the similar issue? If so, please let me know.

Here is the code snippet.

#Region " Methods "

Public Overrides Sub PrintReport()

    ' NOTE: Do not use bug in reportviewer
    'MyBase.PrintReport()

    Dim objRpt As ReportDocument = CType(Me.ReportSource, ReportDocument)

    If m_printDlg Is Nothing Then
        m_printDlg = New PrintDialog
    End If

    m_printDlg.PrinterSettings = ReportEngine.GetPrinterSettings(objRpt)
    m_printDlg.UseEXDialog = True

    'm_printDlg.ShowDialog(Me)
    If m_printDlg.ShowDialog = DialogResult.OK Then
        ReportEngine.PrintReportDocument(objRpt, m_printDlg.PrinterSettings)
    End If

End Sub

End Region

解决方案

Try compiling your application to target any or target x64 (if already any) and see if that has any effect.
