Import A Tab-Delimited File Into Access Using New FileDialog Object

Office 2007 and later versions provide the new Microsoft Office 12.0 or Later Object Library which can be used to create File Picker Dialog boxes, simplifying the coding required.

Details on this technology can be viewed at:

FileDialog Object

In the following example, I illustrate the form which calls the FileDialog Picker, and then imports the tab-delimited file selected to a table.
