Thread: External error

Hi, I am new here. I am a 16 year old high school student. I typed this code for a windows skeleton and i have these 2 errors. IBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/MyWin.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

these errors come up after i execute my code. not after i compile it. these errors have come up on other codes too. this is my code:
#include <windows.h>

LRESULT CALLBACK WindowFunc(HWND, UINT, WPARAM, LPARAM);
char szWinName[] = "MyWin";
int WINAPI WinMain(HINSTANCE hThisInst, HINSTANCE hPrevInst,
LPSTR lpszArgs, int nWinMode)
{
HWND hwnd;
MSG msg;
WNDCLASSEX wcl;

wcl.cbSize = sizeof(WNDCLASSEX);

wcl.hInstance = hThisInst;
wcl.lpszClassName = szWinName;
wcl.lpfnWndProc = WindowFunc;
wcl.style = 0;

wcl.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wcl.hIconSm = NULL;
wcl.hCursor = LoadCursor(NULL, IDC_ARROW);

wcl.lpszMenuName = NULL;
wcl.cbClsExtra = 0;
wcl.cbWndExtra = 0;

wcl.hbrBackground = (HBRUSH) GetStockObject(WHITE_BRUSH);

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

hwnd = CreateWindow(
szWinName,
"Windows 2000 Skeleton",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL,
NULL,
hThisInst,
NULL
);

ShowWindow(hwnd, nWinMode);
UpdateWindow(hwnd);

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


LRESULT CALLBACK WindowFunc(HWND hwnd, UINT message,
WPARAM wParam, LPARAM lParam)
{
switch(message) {
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd, message, wParam, lParam);
}
return 0;
}

please help me out.

Thanks,
Jeff

What compiler are you using? It looks like you may have told your compiler you are building a console application in which case, the compiler will expect you to have coded a main function. The WinMain function is used for a Win32 application, the type of program you indicated you wish to create.

>error LNK2001: unresolved external symbol _main
This looks like an MSVC++ error. Most likely you are trying to compile a Win32 application in a console project, create a new Win32 application and then paste your code into that and recompile, it should remove that particular error.

i tried to create a win32 application and it wouldn't let me exacute it. why
