Just started learning to program in Windows, but I am having a wierd error.

I think it is a problem with my compiler (Visual Studio .NET), it says:

fatal error C1010: unexpected end of file while looking for precompiled header directive

and here is my code:

Code:

#include <windows.h>
#include <stdio.h>

#define CLASS_NAME "Mi Ventana"

LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow)
{
	HWND hwnd;
	MSG msg;
	WNDCLASSEX wndclass;

	wndclass.cbSize = sizeof (wndclass);
	wndclass.style = CS_HREDRAW | CS_VREDRAW;
	wndclass.lpfnWndProc = WndProc;
	wndclass.cbClsExtra = 0;
	wndclass.cbWndExtra = 0;
	wndclass.hInstance = hInstance;
	wndclass.hIcon = LoadIcon(NULL, IDI_WINLOGO);
	wndclass.hCursor = LoadCursor(NULL, IDC_ARROW);
	wndclass.hbrBackground = (HBRUSH) GetStockObject(WHITE_BRUSH);
	wndclass.lpszMenuName = NULL;
	wndclass.lpszClassName = CLASS_NAME;
	wndclass.hIconSm = LoadIcon(NULL, IDI_WINLOGO);

	RegisterClassEx(&wndclass);

	hwnd = CreateWindow(CLASS_NAME, "Ventana 1", WS_OVERLAPPEDWINDOW, 100, 100, 500, 500, NULL, NULL, hInstance, NULL);

	ShowWindow(hwnd, iCmdShow);
	UpdateWindow(hwnd);

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

	UnregisterClass(CLASS_NAME, hInstance);

	return msg.wParam;
}

LRESULT CALLBACK WndProc(HWND hwnd, UINT iMsg, WPARAM wParam, LPARAM lParam)
{
	switch (iMsg)
	{

	case WM_CLOSE:
	case WM_DESTROY:
		PostQuitMessage(0);
		break;
	}

	return DefWindowProc(hwnd, iMsg, wParam, lParam);
}

anyone knows what is the problem?

skim thru your project options and turn off precompiled headers. Then try building again.

Thanks for youre help but I did not find that option, and now I am sure it is not a problem with the code, I get that same error even with tutorials and sample codes I dowloaded, so I am just going to re-install the whole thing.

>>> Thanks for youre help but I did not find that option

Project -> Settings -> C/C++ tab -> Precompiled Headers in the Category list box.

The only "problem" i can see with your code from a quick skim thru is that you use LoadIcon for the WNDCLASSEX::hIconSm. LoadIcon() if you look at the documentation is not guaranteed to work on anything other than icons of size defined by GetSystemMetrics(SM_CXICON) by GetSystemMetrics(SM_CYICON). This commonly does in fact appear to work but the documentation suggests that you use LoadImage() instead.
Your problems should go away when you work out how to turn precompiled headers off.

Thank you all for youre help, I dont know what the problem was but I re-insalled my compiler and the exact same code works perfectly O_O
