ACC: Errors Refreshing Linked Text File via Linked Table Mgr (190186)


The information in this article applies to:

  • Microsoft Access for Windows 95 7.0
  • Microsoft Access 97
This article was previously published under Q190186
Moderate: Requires basic macro, coding, and interoperability skills.

SYMPTOMS

When you try to refresh a link to an external text file by using the Linked Table Manager from within Microsoft Access, you may receive one of the following error messages:
  • Application-defined or object-defined error.

    -or-
  • The text file specification '<Filename> Link Specification' does not exist. You can't import, export, or attach using the specification.

CAUSE

The Linked Table Manager requires an information file called Schema.ini to determine the characteristics of the text file, such as column names, field lengths, and data types. Text files linked through the Link Text Wizard do not use the Schema.ini to determine the characteristics of the file.

RESOLUTION

To resolve this problem, you must first create a Schema.ini file and link the external text file by using the TransferText method in a macro or in a Visual Basic for Applications function.

NOTE: The Schema.ini file must reside in the same folder as the text file(s) it describes.

For more information about creating a Schema.ini, please see the following articles in the Microsoft Knowledge Base:
