I am using the following lines to store file in Access 2007 Ole Object Field

Dim db As Database
Set db = CurrentDb
Dim rs As Recordset
Set rs = db.OpenRecordset("SELECT * FROM Table1 WHERE Id=3")
Dim stm As New ADODB.Stream
stm.Type = adTypeBinary
stm.Open
stm.LoadFromFile "D:\data\swap\aa.txt"
rs.AddNew
rs.Fields("oo").Value = stm.Read
rs.Update
rs.Close

Now my question is how to read that field value and save that stored file in local pc. I am using VBA in access as you see above. Please help

What do you mean by "save that stored file in local pc". Do you have a standard .txt file stored, and you want to output that to the local file system?

Let's be clear...
You have stored this text file as a stream into an OLE field....
Then what is missing here is what this file is supposed to be once it is stored in the OLE field...?
For example, this text file might be an encoded image (UUencode), ...and once read in as a string, this text file might then become the actual image.
...or it could just be  a simple text file...

So we need to be clear on what this text file is supposed to be once stored in the OLE field.

In any event...

I think you then want this to save the OLE object to a file on the disk:

It is using a custom made dll. I am not comfortable to use any third party dll. Any code is welcome without any custom dll or controls.

Thanx

Can I ask why?, it is free and it does what you are asking...
It is effectively the same as if you "Getting the code" and "Encapsulated" (for lack of a better word) it yourself.

...Then you may be out of luck here, this the only product I know of that will do this...
Try contacting Mr Lebans directly.
He states that he will no longer update these utilities, but ask if he would be willing to release the source code.

You can do some deep Googling if you like...
But the code to do this is fairly complex, and I doubt that someone would write code that just does this for MS Access, and post it to the web.
(This is in effect what the Lebans utility does...)
...but again, you can try...

I personally prefer not to reinvent the wheel...
