我在 C++ Visual Studio 中创建简单窗口时遇到问题。我开始了一个新的“空项目”，只创建了一个.cpp文件。当我尝试运行该程序时，我收到此错误：
Unable to start program C:\...\Project1.exe. The system cannot find the file specified.
为什么会这样？我正在使用视觉工作室 2010。
这是我的代码：
#include <windows.h>
// Function prototypes.
LRESULT CALLBACK WndProc( HWND hwnd, UINT message, WPARAM wparam, LPARAM lparam );
int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR szCmdLine, int iCmdShow );
int WINAPI WinMain( HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR szCmdLine,
int iCmdShow )
#pragma region part 1 - STARTUP STUFF
WNDCLASS wc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hbrBackground = (HBRUSH)GetStockObject( WHITE_BRUSH );
wc.hCursor = LoadCursor( NULL, IDC_ARROW );
wc.hIcon = LoadIcon( NULL, IDI_APPLICATION );
wc.hInstance = hInstance;
wc.lpfnWndProc = WndProc;
wc.lpszClassName = TEXT("Philip");
wc.lpszMenuName = 0; // no menu - ignore
wc.style = CS_HREDRAW | CS_VREDRAW; // Redraw the window
RegisterClass( &wc );
HWND hwnd = CreateWindow(
TEXT("Philip"),
TEXT("window's title!"),// appears in title of window
WS_OVERLAPPEDWINDOW,
10, 10,
200, 200,
NULL, NULL,
hInstance, NULL );
ShowWindow(hwnd, iCmdShow );
UpdateWindow(hwnd);

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

}
#pragma endregion
return msg.wParam; // return from WinMain
}
LRESULT CALLBACK WndProc( HWND hwnd, // "handle" to the window that this message is for
UINT message, // TYPE of message (e.g. WM_PAINT is a message asking to paint the window)

{
switch( message )
{
case WM_CREATE:
// upon creation, let the speaker beep at 50Hz, for 10ms.
Beep( 50, 10 );
return 0;
break;
case WM_PAINT:
{
HDC hdc;
PAINTSTRUCT ps;
hdc = BeginPaint( hwnd, &ps );
// draw a circle and a 2 squares
Ellipse( hdc, 20, 20, 160, 160 );
Rectangle( hdc, 50, 50, 90, 90 );
Rectangle( hdc, 100, 50, 140, 90 );

}
return 0;
break;
case WM_DESTROY:

return 0;
break;
}
return DefWindowProc( hwnd, message, wparam, lparam );
}
