Hey everyone....I'm looking to start a new project, but am having a problem getting started!

I want to build a program that I can type the "name" of a file into a text box hit enter and it will open that file up with the right Program.

For Example. If I have a CAD drawing named Test.dwg, I want to type Test into the textbox hit enter and have that drawing open in CAD.

All my drawings are in one location (F:/CAD) but from there they are split into many different subdirectories (F:/CAD/25T) or (F:/CAD/25U)

Does anyone know where i can find something to point me in the right direction?

Thanks
