[fpc-pascal] Win32 API - Inactive Scroll Bar

[soumya at tatamotors.com]

I am new to Windows programming so please bear with me if it is some trivial mistake. I am using FPC.

I have created a window with :
  hWindow := CreateWindow (AppName,'First Prog',ws_OverlappedWindow or WS_VScroll,
                         cw_UseDefault,cw_UseDefault,cw_UseDefault,
                         cw_UseDefault,0,0,system.MainInstance,Nil);

Now after I write some text on the window with TextOut function that goes beyond the window size. I get a scroll bar displayed on the window but the window do not scroll.

Please educate me - what is wrong? 

Is there any good online tutorial or book available. All the material I could get my hand on is meant for Delphi :-(.
