FileGet: Unable to read beyond the end of the stream.

    Question

  • I am trying to use the vb.net method FileGet to populate a type library from a text file.  This text file was created by a legacy application using vb6.  In the vb6 code, the Put method was used to create this file by dumping the type library into the file.  I'm using the same type library to parse back into using the FileGet method.  The only difference is that the type library is now an interop dll.  When I use the FileGet, it works for most of the files that I'm trying to read.  However, there are a few that give me the error:  "Unable to read beyond the end of the stream."  Does anyone know what would cause this error and how I can fix it?  I've already tried to add a space and a line break at the end of the file.  This did not work.  I've searched for the solution but have not found anything that has worked.  Any help would be greatly appreciated!

    Here is part of the code that created the file (legacy vb6 code):

     

    Public Function SaveReport(Optional sFilename As String = sEmpty, Optional bAddToMRU As Boolean = True, Optional bStoreFilename As Boolean = True) As Boolean
     On Error GoTo SaveReport_Error
     Dim iFile As Integer
     Dim intFilterIndex As Integer
     Dim strTemp As String
    
      strTemp = LCase$(Right$(sFilename, 4))
    160 If strTemp <> ".rpt" And strTemp <> ".avr" And strTemp <> ".tmr" And strTemp <> ".tab" And strTemp <> ".csv" And strTemp <> ".ebx" Then GoTo SaveReport_Error:
     
     'Open and populate file
    310 iFile = FreeFile
    320 Open sFilename For Binary As iFile
    330 Put iFile, , ADReport
    340 Close iFile
    
    380 SaveReport = True
     
    400 On Error GoTo 0
    410 Exit Function
    SaveReport_Error:
     Select Case Err.Number
      Case 0
       MsgBox "The filename specified does not seem valid. Please specify a valid filename." + CStr(Err.Number), vbCritical, "File Error"
      Case Else
       MsgBox "An abnormal error has occurred running this program: (" + CStr(Erl) + ") " + CStr(Err.Number) + " - " + Err.Description, vbCritical, "frmCompliance_SaveReport Error"
     End Select
     SaveReport = False
    End Function

     

    Here is the code that I've written to populate the type library from the file:

     

    Public Function ParseReport(ByVal sFileName As String) As MSXML2.IXMLDOMNode
      On Error GoTo ParseReport_Error
      Dim iFile As Short
      Dim ADReport As ADTYPESTLB20Lib.tagUsrADReport
      Dim ReportNode As MSXML2.IXMLDOMNode
    
      ' Open and populate file.
      If sFileName <> sEmpty Then
       iFile = FreeFile()
       FileOpen(iFile, sFileName, OpenMode.Binary, OpenAccess.Read)
       FileGet(iFile, ADReport)
       FileClose(iFile)
      End If
    
      ParseReport = BuildRecordNodes(ADReport)
    
      On Error GoTo 0
      Exit Function
    
    ParseReport_Error:
      Select Case Err.Number
       Case Else
        MsgBox("An abnormal error has occurred running this program: " & CStr(Err.Number) & " - " & Err.Description, MsgBoxStyle.Critical, "ParseReport_Error")
      End Select
     End Function

     

    The exception occurs on this line:

    FileGet(iFile, ADReport)

  • Hello jsh2432,

    Thanks for your post.

    If I understand your problem clearly, do you want to use the VB.NET method FileGet in VB6 application? If so, I suggest you could post you problem on VB6 forum for better support.

    For Visual Basic 6 questions, please read:

  • Hi Liliane,

    Actually, I want to use the VB6 Get method in VB.NET, which is the FileGet method.  I'm writing a report import tool that takes old reports files (created in VB6 using the Get method) and parses them into the object they were created with.  Once I get the object filled, I'm serializing it and storing it in a database to be used by a new application that displays these reports in a different format.

    Thanks.

  • 1.) Get the number of bytes requested and

    2.) The exact size of the file

    3.) And the number of bytes already read

    and come back.

    Hi J. Hamman,

    This thread has resurfaced from over a year ago.

    Anyway, should you come back to this, please see this thread for an example of using

    FileGet

    and

    FilePut

    in Vb.Net
