Hello, I have used this forum to get help many times. I thought it was time to (hopefully) help others. I created a script that reads a text file with a list of videos, displays the videos in a GUI with checkboxes next to the names, and displays the selected videos. This will become a part of a larger script I am creating to test a video player. The tough part for me was creating the GUI and Dynamic list of videos. I had a lot of trouble finding samples to help me, but finally found one written by Melba23. The link is in the code, so he gets credit for helping! I also have not used arrays much and they are very picky about looping through the arrays without getting the dreaded error " Array variable has incorrect number of subscripts or subscript dimension range exceeded." However diligence paid off! To run this code, take the video names commented below and create a videos.txt file in your script execution directory. You can put however many video names in this list. Thus the dynamic features of the code. Cheers!
