以编程方式从Word 2007文档中提取宏(VBA)代码

标签: .net automation ms-office

是否可以使用API​​从Word 2007“docm”文档中提取所有VBA代码?

我已经找到了如何在运行时插入VBA代码,以及如何删除所有VBA代码,但是没有将实际代码拉出到我可以存储的流或字符串中(以及将来插入到其他文档中)。 / p>

任何提示或资源都将受到赞赏。

修改:感谢所有人,Aardvark的答案正是我所寻找的。我已将其代码转换为C#,并且能够使用Visual Studio 2008从类库中调用它。

using Microsoft.Office.Interop.Word;
using Microsoft.Vbe.Interop;

...

public List<string> GetMacrosFromDoc()
{
    Document doc = GetWordDoc(@"C:\Temp\test.docm");

    List<string> macros = new List<string>();

    VBProject prj;
    CodeModule code;
    string composedFile;

    prj = doc.VBProject;
    foreach (VBComponent comp in prj.VBComponents)
    {
        code = comp.CodeModule;

        // Put the name of the code module at the top
        composedFile = comp.Name + Environment.NewLine;

        // Loop through the (1-indexed) lines
        for (int i = 0; i < code.CountOfLines; i++)
        {
            composedFile += code.get_Lines(i + 1, 1) + Environment.NewLine;
        }

        // Add the macro to the list
        macros.Add(composedFile);
    }

    CloseDoc(doc);

    return macros;
}

您可以将代码导出到文件中,然后再将其读回。

我一直在使用下面的代码来帮助我在源代码控制下保留一些Excel宏(使用Subversion&amp; TortoiseSVN)。它基本上在我打开VBA编辑器时保存所有代码到文本文件。我把文本文件放在subversion中,这样我就可以做差异了。你应该能够适应/窃取其中一些在Word中工作。

CanAccessVBOM()中的注册表检查对应于安全设置中的“对Visual Basic项目的信任访问”。

Sub ExportCode()

    If Not CanAccessVBOM Then Exit Sub ' Exit if access to VB object model is not allowed

您必须添加对Microsoft Visual Basic for Applications Extensibility 5.3(或您拥有的任何版本)的引用。我的盒子上有VBA SDK等 - 所以这可能不是办公室随附的。

此外,您还必须专门启用对VBA对象模型的访问 - 请参阅Word选项中的“信任中心”。这是Office提供的所有其他宏安全设置的补充。

此示例将从其所在的当前文档中提取代码 - 它本身是一个VBA宏(并将显示自身和任何其他代码)。还有一个Application.vbe.VBProjects集合来访问其他文档。虽然我从来没有这样做过,但我认为外部应用程序也可以使用这个VBProjects集合来打开文件。这些东西的安全性很有趣,所以它可能很棘手。

我也想知道docm文件格式现在是什么 - 像docx这样的XML?这会是一个更好的方法吗?

Sub GetCode()

    Dim prj As VBProject
    Dim comp As VBComponent
    Dim code As CodeModule
    Dim composedFile As String
    Dim i As Integer

    Set prj = ThisDocument.VBProject
        For Each comp In prj.VBComponents
            Set code = comp.CodeModule

            composedFile = comp.Name & vbNewLine

            For i = 1 To code.CountOfLines
                composedFile = composedFile & code.Lines(i, 1) & vbNewLine
            Next

            MsgBox composedFile
        Next

End Sub
