MidgetsBro, why don't you try and debug it yourself? I mean, I'm not getting at ya or anything, but it would be much easier and quicker if you were to put in a few breakpoints and test it yourself to see why it isn't working for you. Kedaman seems to have got it to work on his computer so the problem should logically be in your implementation of the code.

Make sure you are opening the right file for one thing, I know it might sound patronising but it's probably just a silly little mistake like that that's causing you all the grief. Make sure you have specified the full path for the file or it will create a file named that in the root directory. You can use App.Path for the directory that contains the executable if you need to.
