Question

我的一个.xlt文件的模块中有以下VBA代码：

Public Sub SetShapeTop(ByVal shapeName As String, ByVal topValue As Single)
  ThisWorkbook.ActiveSheet.Shapes(shapeName).Top = topValue
End Sub

在我的VSTO加载项中，我有以下C＃代码尝试调用该VBA函数：

m_worksheet.Application.Run("SetShapeTop", kv.Key, kv.Value, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
  Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
  Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
  Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

该行引发异常，如下所示：

(Excerpt from my log4net logs)

[Exception: COMException]

{Parameters: }
{Message: Cannot run the macro 'SetShapeTop'. The macro may not be available in this workbook or all macros may be disabled.}

  at MSA.Excel.ClusterPresenter.RenderReport(IReportData reportData, IResponseReportParameters reportParams, Worksheet worksheet) in C:\workspace\MSABasketlink\2.0\MSA.Library.UI\Presentation\ClusterPresenter.cs:line 647}

我在这里遗漏了什么吗？如果有人能指出我正确的方向，我真的很感激......！

Answer 1

这是一项安全限制。

转到Excel中的信任中心，然后检查信任对VBA项目对象模型的访问权限。

您的呼叫代码是否在VSTO Addin的启动中运行？如果是这样，可能并非所有东西都已加载。解决这个问题的一种（愚蠢的）方法就是运行它直到它工作。抱歉VB.NET，但C＃应该是类似的

Dim hasRun As Integer
Do 
    hasRun = Me.Application.Run("SetShapeTop", kv.Key, kv.Value)
Until hasRun > 0

另外，请看一下这篇文章：Extend Your VBA Code With VSTO

有一点需要注意的是这段代码如果适当的访问权限将失败未授予VBA宏。

从VSTO代码调用VBA函数时出错
