Copy VBA code from a Sheet in one workbook to anot

Question

I've been using the lines below to compy VBA modules from one workbook to another and I don't know if there is an easier way, but they have been working fine:

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

However now I need to copy VBA code that is in a Sheet, not in a Module. The above method doesn't work for that scenario.

What code can I use to copy VBA code in a sheet from one workbook to another?

Answer 1

This is a compiled code from different sources as well from this very one Post. My contribution is a code that copies ALL your codes from VBE (Sheets/Thisworkbook/Userforms/Modules/Classes) to a new Workbook.

i created this , because i have a corrupt workbook and making a code to recover all that isn't corrupt, including code. (this part only recovers code + references) :

'needs a reference to : 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

Option Explicit

Sub CopyComponentsModules() 'copies sheets/Thisworkbook/Userforms/Modules/Classes  to a new workbook
Dim src As CodeModule, dest As CodeModule
Dim i&
Dim WB_Dest As Workbook
'Dim sh As Worksheet
Dim Comp As VBComponent

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

Next Comp

'Add references as well :
Dim Ref As Reference
For Each Ref In ThisWorkbook.VBProject.References
    'Debug.Print Ref.Name 'Nom
    WB_Dest.VBProject.References.AddFromFile Ref.FullPath
    'Debug.Print Ref.FullPath 'Chemin complet
    'Debug.Print Ref.Description 'Description de la référence
    'Debug.Print Ref.IsBroken 'Indique si la référence est manquante
    'Debug.Print Ref.Major & "." & Ref.Minor 'Version
    'Debug.Print "---"
Next Ref

Err.Clear: On Error GoTo 0

'WB_Dest.Activate

Set Ref = Nothing
Set src = Nothing
Set dest = Nothing
Set Comp = Nothing
Set WB_Dest = Nothing
End Sub

If anyone else lands here searching for VSTO equivalent of Chel's answer, here it is:

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]);
}

Things to note:

1. You must add reference to Microsoft.Vbe.Interop to do this stuff.
2. I'm adding a new general module to the destination workbook, so I didn't need to call DeleteLines. YMMV.

You can't remove and re-import the VBComponent, since that would logically delete the whole worksheet. Instead you have to use CodeModule to manipulate the text within the component:

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)
