Umm.

First of all, why in the world are you using 500x500 as the resolution? Is there any monitor in the world that supports that??? (in fullscreen)

Secondly, the printed letters are a waste of space...

Thirdly, why would you call a DLL like that inside a loop?

Fourthly, things like "hWnd,wSBflags,SB_CTL,SB_VERT,wArrows,ESB_ENABLE_BOTH" will never work, those are parameters and you actually have to set the variables to something, other wise you are saying 0,0,0,0,0...

Fifthly, Im assuming you would have to MAKE a scrollbar first before you can en/disable its buttons, or show it, or whatever. And before you do that you need an actual window gadget area, which DBP doesn't have. It only has a DirectX screen... so the only way I know of using Windows gadgets (ie a scrollbar) in DBP is with RobK's BlueGUI.

Sixthly (hmm?), you cannot have Windows gadgets in a fullscreen so I hope you are running it in windowed mode?

Sorry if that sounded offensive, I wasnt trying to insult you, trust me I made mistakes like those back in the day too.
