BUG:Word 2013 VSTO 无法处理格式为 Header 的图像在文本后面或前面

BUG: Word 2013 VSTO Cannot Handle Image in Header Formatted Behind or In Front of Text

I am cross-posting this question from Microsoft Community 因为我在那里没有得到任何回应,也许这里有人可以对此有所启发。

我注意到使用 VSTO 处理文档时 Word 2013 特有的问题。

该文档在 header 或页脚中包含一个图像,其布局选项设置为 "With Text Wrapping",并且 "Behind Text" 或 "In Front of Text":

如果我使用 VSTO 打开文档然后尝试处理形状,我会遇到以下异常:

The remote procedure call failed. (Exception from HRESULT: 0x800706BE)

我在这里上传了一个复制品:Word2013VstoImageFormattedInHeaderBug.zip

相关代码在WordFieldEnumerator.cs:

private static bool ShapesWithinGroup(Shape shape)
{
    var result = false;
    try
    {
        // shape.GroupItems throws the exception
        if (shape.GroupItems != null && shape.GroupItems.Count > 0)
        {
            result = true;
        }
    }
    catch (UnauthorizedAccessException)
    {
        // This shape is not in a group - ignore
    }
    catch (Exception exception)
    {
        var exceptionString = exception.BuildExceptionString();
        Console.WriteLine(exceptionString);
        Console.WriteLine(exception.StackTrace);
        //throw;
    }

    return result;
}

这是完整的异常和堆栈跟踪:

无论我是否尝试捕获异常都会引发异常,它会导致 Word 2013 崩溃:

这个bug在Word 2016上没有出现,我可以成功处理形状。但是,升级到 Office 2016 不是一种选择。我认为这需要 Office 2013 的修补程序才能修复错误。

我可以做些什么来让它在 Word 2013 上运行吗?我尝试了很多假定的修复,包括多次修复和 re-installs Office 2013,但都无济于事。

形状可以放置在页面上的任何位置,但它们始终附加到文本的锚定范围内。 Select 在迭代锚定到它的形状之前调整当前范围可能会解决 HRESULT 0x80010105 RPC_E_SERVERFAULT 异常。

在您的 GetAllFields() 方法中, Select() 在调用 ProcessShapes().[=14 之前分别 页眉和页脚的范围 =]

foreach (HeaderFooter header in section.Headers)
{
    if (header.LinkToPrevious) // || header.Index != WdHeaderFooterIndex.wdHeaderFooterFirstPage
    {
        continue;
    }

    header.Range.Select();

    // Add the fields in the header
    fields.AddRange(header.Range.Fields.Cast<Field>());

    // Add the fields in the shapes in the header
    var fieldsInShapes = ProcessShapes(header.Shapes.Cast<Shape>());
    fields.AddRange(fieldsInShapes);
}

foreach (HeaderFooter footer in section.Footers)
{
    if (footer.LinkToPrevious) // || footer.Index != WdHeaderFooterIndex.wdHeaderFooterFirstPage
    {
        continue;
    }

    footer.Range.Select();

    // Add the fields in the footer
    fields.AddRange(footer.Range.Fields.Cast<Field>());

    // Add the fields in the shapes in the footer
    var fieldsInShapes = ProcessShapes(footer.Shapes.Cast<Shape>());
    fields.AddRange(fieldsInShapes);
}

不知道对你有没有帮助? (我不是 Word 互操作专家..)

在 class WordFieldEnumerator

评论这段代码后,我做了很多工作
  //foreach (Section section in Document.Sections)
            //{
            //    foreach (HeaderFooter header in section.Headers)
            //    {
            //        if (header.LinkToPrevious) // || header.Index != WdHeaderFooterIndex.wdHeaderFooterFirstPage
            //        {
            //            continue;
            //        }
            //        // Add the fields in the header
            //        fields.AddRange(header.Range.Fields.Cast<Field>());

            //        // Add the fields in the shapes in the header
            //        var fieldsInShapes = ProcessShapes(header.Shapes.Cast<Shape>());
            //        fields.AddRange(fieldsInShapes);
            //    }

            //    foreach (HeaderFooter footer in section.Footers)
            //    {
            //        if (footer.LinkToPrevious) // || footer.Index != WdHeaderFooterIndex.wdHeaderFooterFirstPage
            //        {
            //            continue;
            //        }
            //        // Add the fields in the footer
            //        fields.AddRange(footer.Range.Fields.Cast<Field>());

            //        // Add the fields in the shapes in the footer
            //        var fieldsInShapes = ProcessShapes(footer.Shapes.Cast<Shape>());
            //        fields.AddRange(fieldsInShapes);
            //    }
            //}

它工作得尽可能好,没有错误; 错误是形状在页眉和页脚中,它们有访问问题
