Sweet Dos Window Interface :)

Well this project is not nearly done. Its the begining a very primative Mini OS. Since I am not awesome in Win32 api yet i enjoy making these type of things in DOS. It uses the mouse, but can do nothing with it so far. Working on drag and drop right now. Yes I can see im am far off from finshing this. However i was wondering does anyone know about a double back buffer, I really need help with it. So far i have three kinds of message boxes, and three kinds of windows. I have folders also. The colors of the graidents can be changed through the code itself right now which will change when im done with certain parts. Vote or Comment :*) If anyone can help on Double Buffering pelase IM me AIM\Yahoo: Nit3shift Email: JNixon21@excite.com. Thanks. PS: of program will not run change grpahics intailize to whereever your BGI path is... :(
