关于office自带的OCR

Dim strLayoutInfo As String, strLPN As String
    
     '初始化并加载文档
    Set miDoc = CreateObject("MODI.Document")            '创建对象
    miDoc.Create "D:\未命名.jpg"                         '加载图片文件
    
    Screen.MousePointer = vbHourglass                    '设置光标忙
    '识别
    miDoc.Images(0).OCR miLANG_CHINESE_SIMPLIFIED, True, True '有用的就此一句，识别为中文简体 ============报错行
    
    Set modiLayout = miDoc.Images(0).Layout              '读出数据
    strLayoutInfo = _
        "Language: " & modiLayout.Language & vbCrLf & _
        "Number of characters: " & modiLayout.NumChars & vbCrLf & _
        "Number of fonts: " & modiLayout.NumFonts & vbCrLf & _
        "Number of words: " & modiLayout.NumWords & vbCrLf & _
        "Beginning of text: " & Left(modiLayout.Text, 50) & vbCrLf & _
        "First word of text: " & modiLayout.Words(0).Text
    MsgBox strLayoutInfo, vbInformation + vbOKOnly, "Layout Information"
    Set modiLayout = Nothing
    Set miDoc = Nothing
    Screen.MousePointer = vbDefault

我添加工程->部件->添加这个控件:Microsoft Office Document Imaging 11.0 Type Library
了怎么一运行就报错：
object hasn't been initialized and can't be used yet


另外对于miDoc.Images(0).OCR miLANG_CHINESE_SIMPLIFIED, True, True 要是只识别数字怎么写。

也许只是差一点点，但是对于一个没有系统学过编程的人来说需要的就是您的点滴点拨。谢谢

这个dll我怎么注册不了啊
