I would like to copy the code from a userform using a macro, but I couldn't find any way to do so, help, please.
This function will get the text of a userform, code module, or class module. You'll need the Microsoft VBA Extensibility 5.5 reference that @SHK mentioned.
Function getCodeText(wb As Workbook, moduleName As String) As String
Dim myCode As VBIDE.CodeModule
Set myCode = wb.VBProject.VBComponents.Item(moduleName).CodeModule
getCodeText = myCode.Lines(1, myCode.CountOfLines)
End Function
Sub testCall()
MsgBox getCodeText(Workbooks("MyWorkbook.xlsm"), "MyUserformName")
End Sub
