mscorlib - 值不能为空 - 参数名称：值

Question

我有一个VB.net应用程序已经建立了一段时间。我最近在其中一份报告中的活跃报告6中添加了条形码。

一切正常，我的机器上不如别人，而是有选择的几个获得有关以下内容的错误：

的mscorlib - 值不能为空 - 参数名：价值

有代码如下：

Dim rp As New ARPTSpecialOrderCard 
CType(rp.Sections("pgDetails").Controls("labelVendorPhone"), DataDynamics.ActiveReports.Label).Text = Me.LabelVendorTelephone.Text 
CType(rp.Sections("pgDetails").Controls("labelID"), DataDynamics.ActiveReports.Label).Text = Me.orderid.ToString 
CType(rp.Sections("pgDetails").Controls("bcID"), DataDynamics.ActiveReports.Barcode).Text = Me.orderid.ToString 
rp.Run() 
frmARViewer.Viewer1.Document = rp.Document 
frmARViewer.ShowDialog() 

异常文本：

我需要更新用户机器上的mscorlib.dll吗？我不知道为什么会出现这个错误。

谢谢

从堆栈跟踪看来，您似乎添加了一个无效的字体。确保用户已将其安装在他们的机器上或选择更有保证的字体。
