Win32 fejl? Resource

Hej udviklere!

Jeg har disse tre filer, men når jeg så compiler dem vil vinduet ikke åbne? eller jo men kun i et halvt sekund...

main.cpp

#include "resource.h"
#include <windows.h>

HINSTANCE hInsta;

LRESULT CALLBACK MainWndProc(HWND hwnd, UINT nMsg, WPARAM wParam, LPARAM lParam);

int WINAPI WinMain(HINSTANCE hInst, HINSTANCE hPrev, LPSTR lpCmd, int nShow)
{
 WNDCLASSEX wc;
 HWND hwnd;
 MSG msg;
 hInsta = hInst;
 
    wc.cbSize        = sizeof(WNDCLASSEX);
    wc.style         = CS_HREDRAW | CS_VREDRAW;
    wc.lpfnWndProc   = MainWndProc;
    wc.cbClsExtra    = 0;
    wc.cbWndExtra    = 0;
    wc.hInstance     = hInst;
    wc.hCursor       = LoadCursor(NULL, IDC_ARROW);
    wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
    wc.lpszMenuName  = MAKEINTRESOURCE(IDR_MYMENU);
    wc.lpszClassName = "WndClass";
    wc.hIcon  = LoadIcon(GetModuleHandle(NULL), MAKEINTRESOURCE(IDI_MYICON));
    wc.hIconSm  = (HICON)LoadImage(GetModuleHandle(NULL), MAKEINTRESOURCE(IDI_MYICON), IMAGE_ICON, 16, 16, 0);
 
 RegisterClassEx(&wc);
 
 hwnd = CreateWindowEx(WS_EX_CLIENTEDGE,
 "WndClass",
 "Dam V. 1.0",
 WS_OVERLAPPEDWINDOW,
 20, 20, 700, 700,
 NULL,
 NULL,
 hInst,
 NULL);
 
 ShowWindow(hwnd, nShow);
 UpdateWindow(hwnd);
 
 while(GetMessage(&msg, NULL, 0, 0) > 0)
{
 TranslateMessage(&msg);
 DispatchMessage(&msg);                        
}   
    return msg.wParam;
}

LRESULT CALLBACK MainWndProc(HWND hwnd, UINT nMsg, WPARAM wParam, LPARAM lParam)
{
        switch(nMsg)
        {
        case WM_CREATE:
             {
                   HICON hMyIcon = LoadIcon(hInsta, MAKEINTRESOURCE(IDI_MYICON));          
             }
         case WM_DESTROY:
              PostQuitMessage(0);
         break;   
                 
        default:
        return DefWindowProc(hwnd, nMsg, wParam, lParam);
        }    
}

resource.rc

#include "resource.h"

IDR_MYMENU MENU
BEGIN
    POPUP "&File"
    BEGIN
        MENUITEM "E&xit", ID_FILE_EXIT
    END

    POPUP "&Stuff"
    BEGIN
        MENUITEM "&Go", ID_STUFF_GO
        MENUITEM "G&o somewhere else", 0, GRAYED
    END
END

IDI_MYICON ICON "C:\\\\Documents and Settings\\\\Jakob\\\\Skrivebord\\\\dam.ico"

resource.h

#define IDR_MYMENU 101
#define IDI_MYICON 201

#define ID_FILE_EXIT 9001
#define ID_STUFF_GO 9002

Hvor er fejlen? Compileren melder ingen!

Compiler: Dev-C++ 4.9.9.2

Håber i kan hjælpe
