Well since getting no help i bashed away at the problem and got it to work finally. Here is my working code. SAVE TO MySQL out of Picturebox (pbPicture) <pre><code> Dim filename As String = txtName.Text + ".jpg" Dim FileSize As UInt32 conn.Close() Dim mstream As New System.IO.MemoryStream() PbPicture.Image.Save(mstream, System.Drawing.Imaging.ImageFormat.Jpeg) Dim arrImage() As Byte = mstream.GetBuffer() FileSize = mstream.Length Dim sqlcmd As New MySqlCommand Dim sql As String mstream.Close() sql = "insert into [your table] (picture, filename, filesize) VALUES(@File, @FileName, @FileSize)" Try conn.Open() With sqlcmd .CommandText = sql .Connection = conn .Parameters.AddWithValue("@FileName", filename) .Parameters.AddWithValue("@FileSize", FileSize) .Parameters.AddWithValue("@File", arrImage) .ExecuteNonQuery() End With Catch ex As Exception MsgBox(ex.Message) Finally conn.Close() End Try </code></pre> LOAD from MySQL db Back to Picturebox <pre><code> Dim adapter As New MySqlDataAdapter adapter.SelectCommand = Cmd data = New DataTable adapter = New MySqlDataAdapter("select picture from [yourtable]", conn) </code></pre> NOTE!! can only put once picture in picturebox so obvoiusly this query can only return one record for you <pre><code> commandbuild = New MySqlCommandBuilder(adapter) adapter.Fill(data) Dim lb() As Byte = data.Rows(0).Item("picture") Dim lstr As New System.IO.MemoryStream(lb) PbPicture.Image = Image.FromStream(lstr) PbPicture.SizeMode = PictureBoxSizeMode.StretchImage lstr.Close() </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
