Thanks Stew,
I can import the text file or open a dialog box to read as text file and pass the value to compare in the access table. There will be several files, the users will be comparing the access table and updating. This the reason, I wanted to code using Visual Basic functions and methods. This way the dialog box will ask the text file name and user can enter as they like. At the same note I can also write a macro to import the text file into access table and then compare in the query.
Thanks
