I am working on the same type of project. So far, I have been able to have the user type in the full path of a directory and then have the directory contents searched for all the files with the type I want and upload them all (without preserving directory structure though). I have removed the unnecessary functions from the program, so you may see some references to non-existant functions. They were mostly used for updating a database, so they are unnecessary.
Basically, all I did was use Directory.GetDirectories (currDir) and Directory.GetFiles (currDir) to find out if there were any subdirectories or files in the directory. If there were directories, I would recurse each directory until I found one without any subdirectories. Then, if there were files, I would upload them.
I do appreciate any help in creating a GUI for the form. Currently, I am having serious problems trying to use events with dynamically created objects. Any help is appreciated.
Objects used:
TextBox txtFolder
Button btnSubmit
