View 11 RepliesWhat I am trying to do is be able to remove a handler, add a handler, and a button and add a string to the my.settings. I would like the DLL to be able to do all of this to my form1 in a different project. How my program is setup right now is by the information inside this tutorial. You will be able to find my source code below but it is just a test code that I am using for right now to add to my main project later on. What the program does so far is checks for add-dons (DLL's) and will execute the function Addonloaded inside the DLL. My final goal is to have it so that nothing will be stored inside the program for the add-on's, so that I can easily make add-on's and the users can just add the DLL to their addons folder.[code]...
