WinMain Function

[starcreek]

Ok theres my basic 3:

1. Dev Version 4.9.9.2 with windows 2002

2. I'm trying to create a window using the WinMain() function.

LRESULT WINAPI MsgProc(HWND hWnd, UINT msg, WPARAM wPARAM,
LPARAM 1Param)
{
switch(msg)
{
case WM_DESTROY:
PostQuitMessage(0);
return 0;
break;
}

         return DefWindowProc(hWnd, msg, wParam, 1Param);
         }

         int WINAPI WinMain(HINSTANCE hInst, HINSTANCE prevhInst,
                            LPSTR cmd, int show)
         {
            WNDCLASSEX wc = { sizeof(WNDCLASSEX), CS_CLASSDC, MsgProc, 
                              0, 0, hInst, NULL,
                              NULL, NULL, NULL, "AppClass", NULL };

            RegisterCLassEx(&wc);

            HWND hWnd = CreateWIndow("AppClass", "Window Title",
                           WS_OVERLAPPEDWINDOW, 100, 100, 640, 480,
                           NULL, NULL, hInst, NULL);

            ShowWindow(hWnd, SW_SHOWDEAFUALT);
            UpdateWIndow(hWnd);

            // entejr sloop
            Msg msg;

            Zero Memory(&msg, sizeof(msg));

            while(msg.message != VM_QUIT)
               {
              if(PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
                     {
                        TranslateMessage(&msg);
                        DispatchMessage(&msg);
                        }
                     else
                        {
                           // dosmething to thes cren
                           }
                           }

                           UnregisterdClass("AppClass", wc. hInstance);
                           }

You have not included <windows.h> where such things as LRESULT and WINAPI are defined.

Do not put your projects or source in c:\dev-cpp. Apart from being a fundamentally bad idea to 'pollute' an application installation, it sometimes causes problems that prevent Dev-C++ from building the code.

The easiest way to get started with a Win32 GUI app is to start wit the provided Win32 GUI template project. It will ensure that all the correct compiler and linker settings are applied as well as providing a minimal Win32 framework to get you started. File->New->Project

Symbols in C/C++ may not start with a number (only alphabetic or underscore). On lines 2 and 12 you have 1Param where you meant lParam (lowercase-L and the number 1 are almost indistinguishable in Courier font, but context is usually sufficient to distinguish them. Unfortunately many programming books use Courier). Try using a programming font where such characters are more clearly distinguishable. I recommend Consolas ( http://www.microsoft.com/downloads/details.aspx?familyid=22e69ae4-7e40-4807-8a86-b3d36fab68d3&displaylang=en )

Symbols in C/C++ (or any other programming language I am aware of) cannot contain spaces. So you may want to reconsider this line:

Zero Memory(&msg, sizeof(msg));
