vb 引用office DOMI执行ocr后出现ocr running error

程序运行到modiDocument.OCR miLANG_ENGLISH, False, False出现错误提示ocr running error,按确定后,程序自动关闭了,无法继续运行下去。请教高手，如何判断OCR出现错误，如何让程序不关闭，重新扫描，直到正确为止。

'利用微软OCR控件, 只需要不到10行代码就能够实现自已的OCR文字识别软件.
'1. 添加控件,需要安装office2003, 没有安装office2003的可以从别人机子上拷贝相关文件,注册regsvr32.exe mdivwctl.dll,
'控件一般在这个目录下:C:\Program Files\Common Files\Microsoft Shared\MODI.0, 只需要相关的几个文件就可以了, 此文件夹全部文件大概在21M左右.
'2.工程->部件->添加这个控件:Microsoft Office Document Imaging 11.0 Type Library

Private Function OCRImageFile(ByVal strName As String) As Boolean
    Dim modiDocument As New MODI.Document
    Dim modiImages As New MODI.Images
    Dim modiImage As New MODI.Image
    Dim modiLayout As New MODI.Layout
    Dim ImageCount As Integer
    
    Dim i As Integer
    modiDocument.OCR miLANG_CHINESE_SIMPLIFIED, False, False
   
    Set modiImage = modiDocument.Images
    
    
    For i = 0 To ImageCount
        Set modiImage = modiImages.Item(i)
        Set modiLayout = modiImage.Layout
        Text1.Text = modiLayout.Text
    Next i
    
    modiDocument.Close False: Set modiDocument = Nothing
    
    If ImageCount > 0 Then
        OCRImageFile = True
    Else
        OCRImageFile = False
    End If
End Function

Private Sub Command1_Click()
    Dim bolP As Boolean
    bolP = OCRImageFile(App.Path & "\1.bmp")
End Sub

这个可以成功执行
