Add DBF file to ArcMAP Table of Contents

[DanWolford]

This is my second program using ArcObjects and I am having some technical difficulties.  I have another program I wrote that will allow you to select
tabular information from Excel and Save that to a Dbase *.dbf file where you can provide field attribute information.  This program will be an ArcMap
Add-in that will run the previously mentioned program creating a DBF file.  This DBF file will then be added to open ArcMAP file and then be joined to
an existing SHP file.  I am running 64-bit Windows 7 Professional with Visual Studio Express 2008.

The full source code is in the attached zip file and contains the four routines discussed below.  I only included the AddDBFLayer in this posting.
The routines in the code below is mostly borrowed from ESRI Samples and are all basically just to add the DBF file to ArcMAP.  Each of these programs
have there own errors that are listed in the code.  I would not be surprised if I am not properly assigning the Map Application or the Map Document
variables.  Currently I have 4 main programs called when(OnClick) button is selected.  These 4 programs are just 4 different ways I have attempted to
solve my problem, and I am looking for one good one.

1.) AddDBF - This program gives no errors but does not add the DBF to the Table of Contents?
2.) AddDBFLayer  - This program Calls AddTable which calls OpenTable.  The error occurs when trying to open the table.
3.) AddShapefile -  Error occurs when trying to open the shapefile
4.) AddShapefile2 - Error occurs when trying to open the shapefile.                  

Any and all help would be greatly appreciated.

Thanks
Dan

This might be a data problem rather than a code problem.  Have you tried adding the dbf from the ArcMap add data command (not in code)?

[DanWolford]

Yes and it opened fine.  The SHP\FINAL directory contains not only a DBF but all the files for the complete shape file format.  When I am in ArcMAP and click the ADD button it will not display the dbf if it is part of a shape file (it will display the shp file extension).  So I copied just the DBF to anoth directory and added it fine.  I can add the DBF's that I created with my program, but I can't add them programmatically for some reason.

[AlexanderGray]

Does the program work if the dbf is alone in the folder?

[DanWolford]

No.  I've tried changing the variables tablePathName and tableName, but it won't work.  Both the AddTable and OpenTable routines were obtained from the following link.
Arc Objects/Working with the Map/Performing Basic map functions/
So you can see what I have changed and what I haven't.

Thanks argray1, I figured out what I was doing wrong with the routine.  I had the filename spelled different in one of the directories that I was testing.
