I am an ex program (quite a bit of VB6 back in the day) that needs to brush off some cobwebs and create a small application for work. Basically the app will display 4 image stacks (basically 4 separate powerpoints) at one time and slowly go through each one at a set interval. So at 00:00 all 4 quadrants would have 4 buttons that would all display slide 1, at 00:03 all 4 quadrants would have slide 2 and so fourth.
At the moment I have 4 buttons that are displaying the first slide statically but I cannot integrate a timer. I think this is a permissions issue with multithreading but the timer is within the source file of the form and I do not know how to get around this permission problem. I do have a timer running but I cannot have it's function update a control within the form. Any assistance would be greatly appreciated.
Thank you
