Dao Connection To Access 2007 Database With Attachment Field
Oct 6, 2011I am working on an asp.net project in VS2010 using vb.NET (not VBA) designing an interface to allow a user to upload a file to an access 2007 table attachment field. My understanding is that in order to interface with a table with an attachment field you
must use DAO to connect to the database so that you can expose the attachment field properties. When I try to open the DAO recordset I am getting "COM exception was unhandled by user code" with a message stating "Too few parameters. Expected 3". The error code is -2146825227 and the stacktrace message is "at dao.Database.OpenRecordset(String Name, Object Type, Object Options, Object LockEdit)"

MS Access 2007/2010 Attachment Field Retrieval And Storage
Dec 16, 2011I'm opening this discussion up primarily because I felt that it was inappropriate that Samir Ibrahim and I had hijacked another thread by turning it into a collaborative development thread. This thread will also hopefully serve as a searchable reference for those few who actually make an attempt to search the forum for information before posting a question. For reference the original thread I mentioned is [URL]
This thread is meant to be a repository for our continued collaboration on trying to find a way to update the attachment field using the OLEDB class. Samir believes that he is close to cracking the secret code.:)
Attachment retrieval and updating is a fairly trivial task using the Microsoft Access Database Engine. It is also fairly trival to retrieve the attached files using OLEDb as well. The difficulty comes when trying to add or delete an attachment with OLEDB.
The attachment field is actually a record set where each record consists of six fields. One of these fields is the data field that contains the binary file data. According to the documentation, Access will compress certain file. It appears that compression/decompression is handled behind the scenes so to say and what you are present with is sequence of bytes. The data field consists of sequence of header bytes followed by the actual data. The first four bytes define an offset to the start of the data. One thing that we are trying to determine is the meaning of other bytes in the header.
I have uploaded a sample project at: [URL]
This project is by no means a finished product. It is hard code to retrieve the first record from the included Access database.
Add New Field Or New Table To Access 2007 From Visual Studio 2010 Programmatically

Comparing Field Values Based On Array Data In Access 07?
Aug 11, 2009I have a query in Access 07 that identifies the following fields: ContractID, status, start date and end date. For each contract, I've been able to search a network share and upload its corresponding file; however I need to skip the import and write a record to a table for contracts with the same start and end date. I've included a placeholder (in bold below), but how do I make the date comparison work? Do I need to create a multi-dimensional array for that or can it be done with the code I have?

Try And Catch - Creating A Database Using Access 2007 And VB 2008
Jul 6, 2011I'm creating a database using Access 2007 and Visual Basic 2008.
I'm using the try and catch exception handler in my project. this try and catch are inserted in the Save Record button. here is the code snippet of my try & catch:
CODE:
My problem is that, whenever i add a new record and clicked the Save Record button, the msgbox "Data Update Failed" popped out. But when i recheck, the newly added record was actually successfully saved in the database.
Is there something wrong with my code? The new record is inserted in the database but why does the "Data Update Failed" msgbox was popped out instead of the "Data Saved" msgbox?? I've tried many times but i still cant figure this out. please help.

I've accomplished this with the following

Apr 27, 2010I have a table called MEMBER with fields for mem_id, mem_name, mem_addr, mem_city,mem_state, mem_zip and another table called STATE with state_id, state_addr, state_name in Access 2007.On the Visual Studio 2008 form, there is a combo box for the state. The goal here is to display the state abbreviations, but use the state_id value for the mem_state (there is a foreign key between those two fields).The mem_state is defined as number, the state_id is autonumber. Under the mem_state definition in Access, I used the lookup wizard (on the database that is in the bin/debug folder) to set the following properties:
Display Control - combo box,
Row Source Type - Table/Query,
Row Source - SELECT [State].[state_id], [State].[state_abbr] FROM State ORDER BY
