I know you guys arent here to fix my code... but i have run into a problem
what i am doing is using a treeview to read a file that has been loaded into a text box.
everytime the word ";fold" appears, it will create a new treenode and add children to it until the word ";endfold" appears.
I have it working good up to the point of adding folds within folds.
i can get on into it but the second fold within is where i am having the trouble.
here is the code that i have
