I need to save the image, not the path to a SQL database. I have the following code and it works fine as long as I press "save" in the binding navigator before clicking the button.

I'm trying to make a program where I draw an image from a SpriteID. The way I usually do this with a method is by doing this:PictureBox1.Image - Util.SpriteReader.GetSpriteImage(2334)
This works fine, but I need to make it work through a Bindingsource and my class. So the Bindingsource is setup, everything is working but the image part. I set the "Image" in the DataBinding of the picturebox to my "Image" property... Heres my properties
Public _ItemID As Integer
Public _Image as Image
Public Property ItemID() As Integer

I have the following function to search an access database. When the program loads it has all the records in the dataset ds. Reading around I read about BindingSource.Find and BindingSource.Filter to search a database. My Function is:

record = TblContactsBindingSource.Find("Phone", phone)

I've taken over a winforms project (attached to a SQL Server database) that needs to completed quickly so am trying to work with what the other developer has rather than rewriting it all. He has an admin form with a listview and a datagridview. The idea is to allow a user to edit the lookup tables for the database (customer type, product list, etc). When the form is loaded, the listview is populated (hard-coded) with a list of available tables. Clicking on a table name fills the datagridview with the contents of the table. What he left incomplete was the updating of the database if the user makes updates/inserts to a table.Now, I know that normally you would just call the Update method of the dataadapter, but he passes all his database calls for the entire project through a helper class that will execute parameterized sql queries (for updates/inserts), or return a bindingsource object for displaying data. But this helper class does not expose the underlaying dataadapter.
To populate the datagridview, he uses the following code in the ListBox1_SelectedIndexChanged event:
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As
[code].....
The rest of the app deals with only one record at a time, so when an update is needed, he scrapes the data from the form, builds a parameter array and passes the array and the name of the stored proceedure that handles the update to a method of his helper class called .InsUpDel - which is simply another wrapper that builds a parameterized query, executes the passed stored proceedure and returns the success/fail state of update.But, since this part of the app deals with an entire table rather than just one record, that method doesn't work. So, back to my question: How can I update the database when a change is made to datagridview when all I have is the bindingsource?
I have a windows app that has a bindingNavigator connected to BindingSource that connects to an Access database. I am manually adding a record to the underlying database using an OLEDBConnection/command (cloning the current record). The insert into the database works fine, what I am not sure on how to do is force the bindingNavigatgor to refresh and read the new record and refelect it in the record count/next/previous buttons.Jack

1) Add a new record - I can currently add records text to access database, but not images.
2) Get the ID [URL]I'm not sure how to integrate this code into my code. I am stuck here.
3) Save the image in the filesystem using the ID as a filename - I can save the upload an image and save the image to a directory on my computer, but I am unable to name the image that of the ID of the access database.
4) Update the database to put the filename in the record you just created. - I am unable to do this as well (obviously).
