如何使用PowerShell向Excel工作表添加VBA代码？

Question

我需要在我的Sheet(1)中包含一个Private Sub Worksheet_BeforeDoubleClick (ByVal Target As Range, Cancel As Boolean)。

我能够打开并写入单元格。

$excel = New-Object -ComObject Excel.Application
$workbook = $excel.Workbooks.Add()
$worksheet = $workbook.WorkSheets.item(1)
$worksheet.range("c1","g6").value = "str"
...
$workbook.SaveAs($xlFlie, 50)
$Excel.Application.Quit()

如何将VBA代码放在工作表中（而不是在VBA模块中）？

我尝试了以下方法：

$xlmodule = $workbook.VBProject.VBComponents.Add()
$xlmodule.CodeModule.AddFromString($code)

我收到了这个错误：

无法在 Null 表达式中调用方法。
在位置 .\Build-ADGrpsMembers2Excel.ps1:273 : 5
+ $xlmodule = $workbook.VBProject.VBComponents.Add(1)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation : (:) [], RuntimeException
+ FullyQualifiedErrorId : InvokeMethodOnNull

请注意：本文已经翻译为简体中文。

我需要更改VBA选项为：

$excel = New-Object -ComObject Excel.Application
New-ItemProperty -Path "HKCU:\Software\Microsoft\Office\$($excel.Version)\excel\Security" -Name AccessVBOM -Value 1 -Force | Out-Null
New-ItemProperty -Path "HKCU:\Software\Microsoft\Office\$($excel.Version)\excel\Security" -Name VBAWarnings -Value 1 -Force | Out-Null

我的工作代码如下：

$excel = New-Object -ComObject Excel.Application
New-ItemProperty -Path "HKCU:\Software\Microsoft\Office\$($excel.Version)\excel\Security" -Name AccessVBOM -Value 1 -Force | Out-Null
New-ItemProperty -Path "HKCU:\Software\Microsoft\Office\$($excel.Version)\excel\Security" -Name VBAWarnings -Value 1 -Force | Out-Null

$workbook = $excel.Workbooks.Add(1)
$worksheet=$workbook.WorkSheets.item(1)

$excel.Visible=$true
$excel.DisplayAlerts = $true
$excel.ScreenUpdating = $true

#$worksheet.range("c1","f6").ColumnWidth = 4
#$worksheet.range("c1","f6").Orientation = 90

$xlmodule = $workbook.VBProject.VBComponents.item('feuil1')
$code = @"
Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
End Sub
"@

$xlmodule.CodeModule.AddFromString($code)

$saveName = "$([Environment]::GetFolderPath('desktop'))\Export-Excel ($( ((Get-Date -Format u ) -replace ":", ".") -replace "Z", '' ) ).xlsb"

# savegarde du fichier
$workbook.SaveAs($saveName, 50)

Write-Verbose "Closing $($WorkSheetName)"
$Excel.Workbooks.Close()
Write-Verbose "Exit Excel"
$Excel.Application.Quit

根据此链接https://learn.microsoft.com/en-us/dotnet/api/microsoft.office.interop.excel.xlfileformat?view=excel-pia，$workbook.SaveAs($saveName, 50)不应该是52吗？ - knile

这个答案对我很有帮助，但是我还需要添加另一个模块，所以我做了类似这样的事情

$workbook.VBProject.VBComponents.Add(1) 
$workbook.VBProject.VBComponents.Add(2) 
$workbook.VBProject.VBComponents.Add(3) 

1 代表模块，2 代表用户窗体，3 代表类

如果要获取刚刚添加的模块，它将位于组件数组的最后一个位置

$arrayOfComponents = @($workbook.VBProject.VBComponents)
$justAddedModule = $arrayOfComponents[$arrayOfComponents.Length-1]

因此它看起来像这样

$excel = New-Object -ComObject Excel.Application
$vbaProject = new-object -ComObject VB
$FilePath = "c:\temp\excel.xlsm"
New-ItemProperty -Path "HKCU:\Software\Microsoft\Office\$($excel.Version)\excel\Security" -Name AccessVBOM -Value 1 -Force | Out-Null
New-ItemProperty -Path "HKCU:\Software\Microsoft\Office\$($excel.Version)\excel\Security" -Name VBAWarnings -Value 1 -Force | Out-Null

$workbook = $excel.Workbooks.Add($FilePath)
# Add(1) za dodavanje modula
#$workbook.VBProject.VBComponents.Add(1)

$xlmodule = $workbook.VBProject.VBComponents.item('Module1')


$code = @"
Sub test()
'
End Sub
"@
$xlmodule.CodeModule.AddFromString($code)
$workbook.SaveAs($FilePath,52)
$excel.Workbooks.Close() 
$excel.Application.Quit()
