What's wrong with this code? Why would hwnd return 0x00000000 from CreateDialog, what mistake did I make? How to change

#include <windows.h>
#include <commdlg.h>

#include "resource.h"

BOOL CALLBACK MainDlgProc (HWND, UINT, WPARAM, LPARAM);


int WINAPI WinMain (HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpcmdLine,
int nCmdShow)
{
HWND hwnd;
MSG msg;
Ranch
hwnd = CreateDialog (hInstance, MAKEINTRESOURCE (IDD_TidyMain),
NULL,
MainDlgProc);


ShowWindow (hwnd, SW_SHOW);
UpdateWindow (hwnd);

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

BOOL CALLBACK MainDlgProc (HWND hDlg,
                          UINT message,
                          WPARAM wParam,
                          LPARAM lParam)
{
switch (message)
{
case WM_INITDIALOG:
return TRUE;
case WM_COMMAND:
switch (LOWORD (wParam))
{

}

return FALSE;
case WM_CLOSE:
EndDialog (hDlg, 0);
return TRUE;
}

return FALSE;
}
