使用C＃检查Excel工作簿是否具有宏

Question

I need to go through hundreds of Excel files to find those that have macros, using a C# client.

I have tried using the code in the accepted answer here:

Using Interop.Excel to check if Excel file contains VBA Macros

However, this code opens the file first. Many of the files are opening pop up Windows and VBA error messages even after adding _appExcel.DisplayAlerts = false

Its also very slow. Is there a better way to go about this, ideally without opening the Excel file first?

I have looked for documentation on MSDN for Excel interop here: HasVBProject but there are no examples I can work with.

Answer 1

try this

f = Dir("*.xls*")
While f <> ""
On Error Resume Next
    Set wb = Workbooks.Open(f)
    If wb.HasVBProject Then
       Debug.Print wb.Name & " has macro"
    Else
        Debug.Print wb.Name & "does not have macro"
    End If
    wb.Close
    f = Dir
Wend

如果工作簿事件是问题，那么您可以通过AutomationSecurity属性使用Interop.Excel命名空间禁用所有宏：

MyExcel.Application.AutomationSecurity = Microsoft.Office.Core.MsoAutomationSecurity.msoAutomationSecurityForceDisable;
