问题描述
Hi.
I have a code which should allow for images to open in the form in c# but buttons 3 and 5 aren't working for some reason and I can't find the problem. The code executes ok, but when I press the buttons I get no response. The other 3 buttons, load image / load image / button 4, are all working correctly.
I have attached an image with the designer form on to show the layout. If anyone can advise me on what the problem is I would be very thankful.
