    Odd windows problem

    I was creating a basic window, and when I tried to compile it I got these errors

    c:\program files (x86)\microsoft sdks\windows\v7.0a\include\objidl.h(11280): error C2061: syntax error : identifier '__RPC__out_xcount_part'
    c:\program files (x86)\microsoft sdks\windows\v7.0a\include\objidl.h(11281): error C2059: syntax error : ')'
    c:\program files (x86)\microsoft sdks\windows\v7.0a\include\objidl.h(11281): fatal error C1903: unable to recover from previous error(s); stopping compilation
    Here is my code

    //Include the windows header files
    #include <Windows.h>
    HINSTANCE hInst;
    HWND wndHandle;
    int width = 640;
    int Height = 480; 
    //Forward declerations
    bool InitWindow(HINSTANCE hInstance, int width, int height);
    int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
    	//Initialize the window
    		  return false;
    	//Main message loop
    	MSG msg = {0};
    	while(msg.message != WM_QUIT)
    		while(PeekMessage(&msg, wndHandle, 0, 0, PM_REMOVE))
    		//Aditional game logic can go here
    	return msg.message;
    bool InitWindow(HINSTANCE hInstance, int width, int height)
    	WNDCLASSEX wcex;
    	wcex.cbSize = sizeof(WNDCLASSEX); = CS_HREDRAW | CS_VREDRAW;
    	wcex.lpfnWndProc = WndProc;
    	wcex.cbClsExtra = 0;
    	wcex.cbWndExtra = 0;
    	wcex.hInstance = hInstance;
    	wcex.hIcon = 0;
    	wcex.hCursor = LoadCursor(hInstance, IDC_ARROW);
    	wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
    	wcex.lpszMenuName = NULL;
    	wcex.lpszClassName = TEXT("DirectXExample");
    	wcex.hIconSm = 0;
    	//Resize the window
    	RECT rect = {0, 0, width, height};
    	AdjustWindowRect(&rect, WS_OVERLAPPEDWINDOW, FALSE);
    	//Creaete the window from the class above
    	wndHandle = CreateWindow(TEXT("DirectXExample"), TEXT("DirectXExample"), WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, rect.right - rect.left,
    		rect.bottom -, NULL, NULL, hInstance, NULL);
    		return false;
    	//Display the window on the screen
    	ShowWindow(wndHandle, SW_SHOW);
    	return true;
    LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
    	//Check the message queue
    	case WM_KEYDOWN:
    			//Check if the user hit the Escape Key
    		case VK_ESCAPE:
    		//The user hit the close button, close the application
    	case WM_DESTROY:
    	//Always return the message to the default window procedure for further processing
        return DefWindowProc(hWnd, message, wParam, lParam);
    Thank you in advance.

    I'm not sure about your code, if you have solved the problem then omit my comment; I have done only an overview, and find 2 things: you are calling a function without parentheses (and without arguments) on line 16, you should pass the arguments to the function is expected to get; the second is that you are using a wrong struct type while registering class in line 52, take a look at MSDN->RegisterClass and see what struct is expecting, also take a look at RegisterClassEx

    Also a simple observation: why do you declare a variable 'width' and then 'Height'? (Note the capitalize); it's only for code presentation purposes, since both are at the same 'level', why you don't write them on the same format?

    Hope that helps

    What sort of project type are you using, a win32, .net, or managed. I only use win32 projects, but that looks like it is using some interface related stuff, i.e. COM objects. But an undefined error in a windows header most probably indicates a '#define' error. You should get an error for calling RegisterClass with an 'WNDCLASSEX' structure and the 'InitWindow' just as Niara said. They just don't make it to compilation.

    Use lower case windows '#include <windows.h>'

    and try preceeding it with '#define _WIN32_WINNT 0x600'

    or whatever version is applicable to windows 7 > than 0x600 if any.

    i once had the same problem, after i installed directx sdk. if you have another sdk installed, such as directx, you should check the include directories (tools>options>project and solutions>VC++ directories - for VC++) and make sure the standart windows directories come first, not the other ones.

    i hope it helps...
