HELP ! Picture box problems

[blazingmavrick]

Hi

My problem consits of the following:-

i am creating mulitple picturebox's, when the user double clicks on the picture box it opens the opendialog box to load a picture (jpeg only) into the picture box.

When they have finished they press a button to save the picture's into certain files called Module1.jpeg, Module2.jpeg and so on. These files are created and saved automatically (i.e. not using the save dialog box).

When the whole application is open'd again the user presses a button to load all the save'd images into there picturebox's respectfully.

If the user then presses save again only changing one picture and the others are not changed then i get a ExtarnalExcepti on handler problem. i have caught the exception with (catch).

How do i do something with this (catch) how do i save the images that have been loaded inn so that the ExternalExcepti on goes away??

bit of a newb to this, any help in simple terms would be greatly apreciated :-)

thanks in advance

Pass the user ID in session

Save the files with the user ID's Concatenated.

Don't use Open Dialog to save files.

Use file upload to do the same.

Retrieve the same files using the user ID (In the file name)

The other option is storing the same in the DB.

thanks for the help but i think i may of post this thread in the wrong place im developing a form in vb 2005.

not sure what you mean by ID sessions.

sorry to be a pain but i am really new to this.

here is the problem code:-

Try
            If PictureBox1.Enabled = True Then
                PictureBox1.Image.Save(FilePic1)
            End If
        Catch ex As NullReferenceException
        Catch ex As Exception
        End Try

this works first time around, it saves the image to the (filepic1) and when loaded back in by this code:-

 Try
            Dim img1 As Image
            Dim fs1 As New FileStream(FilePic1, IO.FileMode.OpenOrCreate)
            img1 = Image.FromStream(fs1, OpenShare.Shared)
            fs1.Close()
            PictureBox1.Image = img1
            PictureBox1.Refresh()
        Catch ex As System.ArgumentException
        Catch ex As IOException
        End Try

it works fine. Its just when you press save again without changing the image(i.e. opening up dialog box and selecting new pic) it does not save anything !

close the programme and load the pictures back into there picturebox's respectfully and the one that was not changed(i.e. the one not saved) shows a blank picture box.

im really struggling with this :-(
