hello. I need help with my first windows program. I dont know what''s wrong with the codes cause the compiler said "unexpected end of file while searching for precompiled header files. I really dont know what went wrong as I double-checked it. Please, anyone pls help me find out the problem. Here''s the source: #define WIN32_LEAN_AND_MEAN #include <windows.h> #include <windowsx.h> #include <iostream.h> #include <stdio.h> #include <math.h> #define WINDOW_CLASS_NAME "WINCLASS1" LRESULT CALLBACK WindowProc(HWND hwnd, UINT msg, WPARAM wparam, LPARAM lparam) { PAINSTRUCT ps; HDC hdc; switch(msg) { case WM_CREATE: { return (0); } break; case WM_PAINT: { hdc= BeginPaint(hwnd,&ps); EndPaint(hwnd, &ps); return (0); } break; case WM_DESTROY: { PostQuitMessage(0); return(0); } break; default:break; } return (DefWindowProc(hwnd, msg, wparam, lparam)); } ////WINMAIN//////// int WINAPI WinMain(HINSTANCE hinstance, HINSTANCE hprevinstance, LPSTR lpcmdline, int ncmdshow) { WNDCLASSEX winclass;//hold winclass HWND hwnd; MSG msg; winclass.cbSize= sizeof(WNDCLASSEX); winclass.nostyle= CS_DBLCLKS | CS_OWNDC | CS_HREDRAW | CS_VREDRAW; winclass.lpfnWndProc= WindowProc; winclass.cbClsExtra=0; winclass.cbWndExtra=0; winclass.hInstance= hinstance; winclass.hIcon= LoadIcon(NULL,IDI_APPLICATION); winclass.hCursor=LoadCursor(NULL, IDC_ARROW); winclass.hbrBackground= GetStockObject(BLACK_BRUSH); winclass.lpszMenuName= NULL; winclass.lpszClassName= WINDOW_CLASS_NAME; winclass.hIconSm= LoadIcon(NULL, IDI_APPLICATION); if (!RegisterClassEx(&winclass)) return (0); if (!(hwnd=CreateWindowEx(NULL, WINDOW_CLASS_NAME, "Gib Records", WS_OVERLAPPEDWINDOW | WS_VISIBLE, 0,0, 400,400, NULL, NULL, hinstance, NULL))) return(0); while(GetMessage(&msg, NULL, 0, 0)) { TranslateMessage(&msg); DispatchMessage(&msg); } return(msg.wParam); }//End of source file Thank you, and sorry if this bothered you. You can reply to my email: jokerarnold@loveletter.org Thanks.

Hi,

First you don''t need to declare so much header files (atleast in this case). Just

#include <windows.h>

will do the trick for you.

I am not sure about your problem, but there is something to do with the return functions. (That''s what end of file indicates) I think.

Try ...

return DefWindowProc(hwnd, msg, wparam, lparam);

instead of

return (DefWindowProc(hwnd, msg, wparam, lparam));

and

return msg.wParam

instead of

return(msg.wParam);

Its PAINTSTRUCT not PAINSTRUCT.

and

winclass.hbrBackground= (HBRUSH)GetStockObject(BLACK_BRUSH);

not

winclass.hbrBackground= GetStockObject(BLACK_BRUSH);

and its

winclass.nostyle= CS_DBLCLKS | CS_OWNDC | CS_HREDRAW | CS_VREDRAW;

not

winclass.nonostyle= CS_DBLCLKS | CS_OWNDC | CS_HREDRAW | CS_VREDRAW;

OK! Now, try these and it shall work.

Now it works on my compiler which is Microsoft Visual C++ 6

I can survive anything ... even NUKES!!!

Thank you very much!! But...it still said
"fatal error C1010: unexpected end of file while looking for precompiled header directive."
I''d followed your instruction but...help?

Here''s the modified codes:
#define WIN32_LEAN_AND_MEAN

#include <windows.h>
#include <windowsx.h>
#include <iostream.h>
#include <stdio.h>
#include <math.h>

#define WINDOW_CLASS_NAME "WINCLASS1"

LRESULT CALLBACK WindowProc(HWND hwnd, UINT msg, WPARAM wparam, LPARAM lparam)
{
PAINTSTRUCT ps;
HDC hdc;

switch(msg)
{
case WM_CREATE:
{
return (0);
} break;

case WM_PAINT:
{
hdc= BeginPaint(hwnd,&ps);

EndPaint(hwnd, &ps);
return (0);
} break;

case WM_DESTROY:
{
PostQuitMessage(0);
return (0);
} break;
default:break;
}

return DefWindowProc(hwnd, msg, wparam, lparam);
}

////WINMAIN////////
int WINAPI WinMain(HINSTANCE hinstance, HINSTANCE hprevinstance, LPSTR lpcmdline, int ncmdshow)
{
WNDCLASSEX winclass;//hold winclass
HWND hwnd;
MSG msg;

winclass.cbSize= sizeof(WNDCLASSEX);
winclass.nostyle= CS_DBLCLKS | CS_OWNDC | CS_HREDRAW | CS_VREDRAW;
winclass.lpfnWndProc= WindowProc;
winclass.cbClsExtra=0;
winclass.cbWndExtra=0;
winclass.hInstance= hinstance;
winclass.hIcon= LoadIcon(NULL,IDI_APPLICATION);
winclass.hCursor=LoadCursor(NULL, IDC_ARROW);
winclass.hbrBackground= (HBRUSH)GetStockObject(BLACK_BRUSH);
winclass.lpszMenuName= NULL;
winclass.lpszClassName= WINDOW_CLASS_NAME;
winclass.hIconSm= LoadIcon(NULL, IDI_APPLICATION);

if (!RegisterClassEx(&winclass))
return (0);

if (!(hwnd=CreateWindowEx(NULL, WINDOW_CLASS_NAME, "Gib Records", WS_OVERLAPPEDWINDOW | WS_VISIBLE, 0,0, 400,400, NULL, NULL, hinstance, NULL)))
return (0);

while(GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);

DispatchMessage(&msg);
}

return msg.wParam;
}

Thank you. Where you from ?(just curious)

I pasted the modified code and the only part the compiler complained about was the ".nostyle" bit. I changed it to ".style" and it compiled fine.

Try starting a new win32 app and pasting in the code from your post here, then make that change. The error you''re getting might be a result of some other problem.

if that only how a window.. i think it''s to much code.


#include <windows.h>

LRESULT CALLBACK WndProc(HWND hwnd,UINT msg,LPARAM lparam,WPARAM wparam)
{
  switch(msg)
  {
   case WS_CLOSE:
        DestroyWindow(hwnd);
   break;

   case WS_DESTROY:
        PostQuitMessage(0);
   break;

   default:
    return DefWindowProc(hwnd,msg,lparam,wparam);
  }

return 0;
}

int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine, int nCmdShow)

{
  WINCLASS wnd;
  HWND     hwnd;
  MSG      msg;

  wnd.style         = 0;
  wnd.lpfnWndProc   = WndProc;
  wnd.cbClsExtra    = 0;
  wnd.cbWndExtra    = 0;
  wnd.hInstance     = hInstance;
  wnd.hIcon         = LoadIcon(NULL,0);
  wnd.hCursor       = LoadCursor(NULL, IDC_ARROW);
  wnd.hbrBackground = (HBRUSH)GetStockObject(COLOR_BLACK);
  wnd.lpszMenuName  = NULL;
  wnd.lpszClassName = "WHATEVER";

  if(!RegisterWindow(&wnd))
   {
      MessageBox(NULL,"Could not REGISTER CLASS","ERROR",MB_OK);
      return 0;
   }

  hwnd = CreateWindowEx(
		NULL,
		"WHATEVER",
		"My first window",
		WS_OVERLAPPEDWINDOW,
		100,100,300,300,
		NULL,
		NULL,
		hInstance,
		NULL);                   

  if(hwnd == NULL)
    {
        MessageBox(NULL, "Window Creation Failed!", "Error!",
            MB_ICONEXCLAMATION | MB_OK);
        return 0;
    }

   ShowWindow(hwnd,nCmdShow); 
   UpdateWindow(hwnd);

   while(GetMessage(&msg, NULL, 0, 0) > 0)
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
    return Msg.wParam;
}

This error occurs when you''ve told MSVC you''re going to use precompiled headers, but leave out the special header directive.

There''s an option in the project configuration not to use precompiled headers.... find it and use it.

if your having pre-compiled header problems then just turn them off...

the option is somewhere in the project properties...

thx k bye

or... alternatively i think you can jsut #include stdafx.h in your project to fix the problem... i think that _might_ fix it...

/me thinks

Bad monkey!
