I am creating a small movie application using MS VB .Net. On my form I have a two TextBoxes, ComboBox, a Button, and a PictureBox. What I would like to do is when the MovieID TextBox equals "10" (or any other number), I click the button and the corresponding Images number will be inserted into the PictureBox. For example: C:\Images is where all my Images are stored. When the MovieID Textbox = "10", the Picturebox will be populated by the Image name "10", when the button is clicked. If the MovieID Textbox = "23", then the PictureBox will be populated by the Image name "23".
