Hello

I'm am looking to do some sort of scenario management system. Basically a form pops up asking the user if they want to create a new scenario or open an existing scenario. A new scenerio is simply a template (excel) file being opened and saved, with the filename being whatever the scenario represents. All the scenario files are saved in one directory. C:\scenarios\
OK this I can do
But when it comes to opening existing scenarios I am stuck, I basically want the user to press the 'open existing scenario' button and get the open file dialogue box showing all the files in the above directory for them to choose from. Can anyone direct me on how to get this box and get it to point to the right directory

Many Thanks
