将Word文档用户表单复制到另一个

Question

I have this code below to copy VBA codes from one word document to another (I'm using C#). It works for modules however I can't seem to get it to work with userforms.

VBComponent sourceVBC = GetSourceDocVB();
VBComponent targetVBC = document.VBProject.VBComponents.Add(sourceVBC.Type);
string codes = sourceVBC.CodeModule.get_Lines(1, sourceVBC.CodeModule.CountOfLines);
targetVBC.CodeModule.AddFromString(codes);
targetVBC.Name = sourceVBC.Name;

Yes, the userform is copied to the target document but its fields are not. Like if it contains labels and textboxes. Those fields are not copied. Am I missing something here?

Answer 1

Yes, you are missing something. Forms are not defined in the code file only, but need a binary file too. You don't tell anything about the way the source files are generated. Normally, in VBA, you use the "Export" statement of the VBComponent object. Of course one can do it manually by going to the VBA Editor in Word, right-clicks the project component and selects "Export". If you have a look into the export folder, you'll see that a form is saved as two files "Form1.frm" (containing the code) and "Form1.frx" (containing binary form data, as labels and other stuff). In the other project, you can use maually the File, Import function, which takes care of the binary definition if you import a form.

In VBA, you may use something like this to export from a project:

For Each vbC In ActiveDocument.VBProject.VBComponents
  Select Case vbC.Type

    Case vbext_ct_StdModule
        strVbcExt = ".bas"
    Case vbext_ct_ClassModule
        strVbcExt = ".cls"
    Case vbext_ct_MSForm
        strVbcExt = ".frm"
    Case Else
  End Select

  strvbCName = vbC.Name
  strFilename = strPath & "\" & strvbCName & strVbcExt
  vbC.Export strFilename
(omitted the rest)

And to import you'll use

ActiveDocument.VBProject.VBComponents.Import strFilename
