I would suggest you stop right there before it's too late. VB6 is long dead and offers no benefits to a new developer. Get yourself a copy of the latest
Visual Studio Express[
^] and get to work on something useful, and fully supported. Note: scroll down the page to the item titled
Express 2013 for Windows Desktop and download and install on your system.
Oh, and forget MDIForms, that is also deprecated technology.
