将一个工作簿中的工作表中的VBA代码复制到另一个工作簿？

Posted 2021-04-12

我一直在使用下面的行将VBA模块从一个工作簿复制到另一个工作簿，我不知道是否有更简单的方法，但它们一直工作正常：

Set srcVba = srcWbk.VBProject
Set srcModule = srcVba.VBComponents(moduleName)

srcModule.Export (path) 'Export from source
trgtVba.VBComponents.Remove VBComponent:=trgtVba.VBComponents.Item(moduleName) 'Remove from target
trgtVba.VBComponents.Import (path) 'Import to target

但是现在我需要复制Sheet中的VBA代码，而不是模块中的VBA代码。上述方法不适用于该场景。

我可以使用什么代码将工作表中的VBA代码从一个工作簿复制到另一个工作簿？

答案

您无法删除并重新导入VBComponent，因为这会从逻辑上删除整个工作表。相反，你必须使用CodeModule来操作组件中的文本：

Dim src As CodeModule, dest As CodeModule

Set src = ThisWorkbook.VBProject.VBComponents("Sheet1").CodeModule
Set dest = Workbooks("Book3").VBProject.VBComponents("ThisWorkbook") _
    .CodeModule

dest.DeleteLines 1, dest.CountOfLines
dest.AddFromString src.Lines(1, src.CountOfLines)

另一答案

如果有人在这里寻找VSTO相当于Chel的答案，这里是：

void CopyMacros(Workbook src, Workbook dest)
{
  var srcModule = src.VBProject.VBComponents.Item(1).CodeModule;
  var destModule = dest.VBProject.VBComponents.Add(Microsoft.Vbe.Interop.vbext_ComponentType.vbext_ct_StdModule);

  destModule.CodeModule.AddFromString(srcModule.Lines[1, srcModule.CountOfLines]);
}

注意事项：

1. 您必须添加对Microsoft.Vbe.Interop的引用才能执行此操作。
2. 我正在向目标工作簿添加一个新的通用模块，所以我不需要调用DeleteLines。因人而异。

另一答案

Patrick的代码不适用于Worksheets（事实上，它会将代码传输到错误的模块）。解决方法是在目标工作簿中创建新工作表，然后复制代码（也可以复制并粘贴工作表数据/函数/格式）。

另一件不起作用的是UserForms。您可以复制代码，但我不知道如何在不使用导出/导入方法的情况下复制实际表单（包括所有控件）。

扩展Patrick的代码：

'Needs reference to : Microsoft Visual Basic for Application Extensibility 5.3 ,
'or run this code : thisworkbook.VBProject.References.AddFromFile "C:\Program Files (x86)\Common Files\Microsoft Shared\VBA\VBA6\VBE6EXT.OLB"
'from immediate window (ctrl+G) or create a small sub

' What works:   Successfully tranfsers Modules with code and name
'               Copies userform code and name only, but the form is blank (does not transfer controls)
'               Copies code in sheets but no content (optionally add code to copy & paste content)
'               Successfully transfers Classes with code and name

另一答案

这是来自不同来源的编译代码以及这一个帖子。我的贡献是将所有代码从VBE（Sheets / Thisworkbook / Userforms / Modules / Classes）复制到新工作簿的代码。

我创建了这个，因为我有一个损坏的工作簿，并制作代码来恢复所有没有损坏的代码，包括代码。 （此部分仅恢复代码+引用）：

'Set sh = ThisWorkbook.Sheets(1)
'sh.Cells.Clear

Set WB_Dest = Application.Workbooks.Add
On Error Resume Next 'needed for testing if component already exists in destination WorkBook and for cross-references.
For Each Comp In ThisWorkbook.VBProject.VBComponents

            'i = i + 1
            'sh.Cells(i, 1).Value = Comp.Name

            'Set Source code module
            Set src = Comp.CodeModule  'ThisWorkbook.VBProject.VBComponents("Sheet1").CodeModule

            'test if destination component exists first
            i = 0: i = Len(WB_Dest.VBProject.VBComponents(Comp.Name).Name)
            If i <> 0 Then 'or: if err=0 then
                Set dest =     WB_Dest.VBProject.VBComponents(Comp.Name).CodeModule
            Else 'create component
                With WB_Dest.VBProject.VBComponents.Add(Comp.Type)
                    .Name = Comp.Name
                    Set dest = .CodeModule
                End With
            End If

            'copy module/Form/Sheet/Class 's code:
