If you're not getting any errors, but your database is not being modified, then either there is no record in your database with the specified ID, or you're updating the wrong database.

One common problem is having a copy of your Access database as part of your project, and setting it to copy that file to the output directory. This will overwrite any changes you have made whilst your application was running.

You need to debug your code - in particular, check the value returned from the ExecuteNonQuery method, which will tell you the number of rows which were affected. In this case, it should return 1 - anything else indicates a problem with your data or your @ID parameter.

Quote:
VB.NET
Dim fs As FileStream
fs = New FileStream(imgName, FileMode.Open, FileAccess.Read)
Dim picturebytes As Byte() = New Byte(fs.Length - 1) {}
fs.Read(picturebytes, 0, System.Convert.ToInt32(fs.Length))
fs.Close()
You can simplify that block to a single line:
VB.NET
Dim picturebytes As Byte() = File.ReadAllBytes(imgName)
