[Dev-C++] Win32 API question

[Chad S. <ho...@ho...>]

I'm a pretty competent C++ programmer, but all my experience is with non-gui 
type programs of the type most often found running on unix systems.

That being said I'm currently trying to learn the Win32 API and I have 
researched a lot of online tutorials, but when trying to compile an example 
program (which I've included below) with mingw in Bloodshed Dev-C++ I keep 
getting these errors:

main.cpp: In function `int WinMain(void *, void *, CHAR *, int)':
main.cpp:53: ANSI C++ forbids implicit conversion from `void *' in 
assignment
main.cpp:69: ANSI C++ forbids implicit conversion from `void *' in argument 
passing

However after a bit of research I found that I could compile with no errors 
if I use the preprocessor definition

#define NO_STRICT

Which basically insures that STRICT is not defined. So anyway, here's the 
code that's giving me problems.

main.cpp
==========================================================

//===================================//
//            Hello.C                //
//           HELLO WORLD             //
//===================================//

#include <windows.h>

long APIENTRY WndProc( HWND hwnd,   UINT msg,
                       UINT wParam, LONG lParam )
{
   HDC         hdc;
   PAINTSTRUCT ps;
   RECT        rect;

   switch( msg )
   {
      case WM_PAINT:
         hdc = BeginPaint( hwnd, &ps );
         GetClientRect( hwnd, &rect );
         DrawText( hdc, "Hello, World! (Windows Style)", -1, &rect,
                   DT_SINGLELINE | DT_CENTER | DT_VCENTER );
         EndPaint( hwnd, &ps );
         return( 0 );

      case WM_DESTROY:			// message: window being destroyed
         PostQuitMessage(0);
         break;

      default:						// if msg unproccessed,
                                                        // return to Windows
         return( DefWindowProc( hwnd, msg, wParam, lParam ) );
   }
   return TRUE;
}

int APIENTRY WinMain( HANDLE hInstance,    HANDLE hPrevInstance,
                      LPSTR  lpszCmdParam, int    nCmdShow )
{
   static char szAppName[] = "WinHello";
   HWND        hwnd;
   MSG         msg;
   WNDCLASS    wc;

   if( ! hPrevInstance )
   {
      wc.style         = CS_HREDRAW | CS_VREDRAW;
      wc.lpfnWndProc   = WndProc;
      wc.cbClsExtra    = 0;
      wc.cbWndExtra    = 0;
      wc.hInstance     = hInstance;
      wc.hIcon         = LoadIcon( NULL, IDI_APPLICATION );
      wc.hCursor       = LoadCursor( NULL, IDC_ARROW );
      wc.hbrBackground = GetStockObject( WHITE_BRUSH );
      wc.lpszMenuName  = NULL;
      wc.lpszClassName = szAppName;
      RegisterClass( &wc );
   }
   hwnd = ::CreateWindow(
      szAppName,                                   // window class name
      "My First Program: Hello World",             // window caption
      WS_OVERLAPPEDWINDOW,                         // window style
      100,                                         // initial X position
      100,                                         // initial Y position
      400,                                         // initial X size
      200,                                         // initial Y size
      NULL,                                        // parent window handle
      NULL,                                        // window menu handle
      hInstance,                                   // program instance 
handle
      NULL  );                                     // creation parameters
   ShowWindow( hwnd, nCmdShow );
   UpdateWindow( hwnd );


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