The error is quite clear - You have the file open in another process, or if this is on a server someone has the file open.
As an aside your code is vulnerable to SQL Injection Attack - don't concatenate strings to create sql commands - use parameters instead

Dim Get_Image_From_Product_Image As New SqlCommand("SELECT Business_Image FROM ImageDB.dbo.Administrator_Account Where Employee_Code = @Employee_Code", sqlcon)
Get_Image_From_Product_Image.Parameters.AddWithValue("@Employee_Code", CmbUserCode.SelectedItem)

As CHill60 says, the error message is pretty clear - the file you are trying to write to is in use. Almost certainly, it's in use by your own software - so start by checking everywhere you read or write that file. Unless you Close (and preferably Dispose) all the stream you use when you are finished with them, they remain open and you app cannot use that file again.
The same thing applies if you load an Image from the file: the source file remains locked until the Image has been Disposed or your app closes, whichever comes first.
