Win32 API CreateWindowW conflicts with Menu Creation

Question

I'm trying to add some application controls into my Windows API code (Note: I am using Visual Studio) I am experiencing a problem where I try to add in a CreateWindowW() function that generates text and a field ("static" and "edit") and a menu at the same time. The menu works fine on its own ("Calculations"):

However, adding the CreateWindow() function "erases" the menu entirely but yields the CreateWindowW() outputs (also flickers a bit):

The code I have right now is this (the menu function and the CreateWindowW() functions are at the bottom):

#define MAX_LOADSTRING 100
#define FILE_MENU_DESTROY 1
#define FILE_MENU_ABOUT 2

// Global Variables:
HINSTANCE hInst;                                // current instance
WCHAR szTitle[MAX_LOADSTRING];                  // The title bar text
WCHAR szWindowClass[MAX_LOADSTRING];            // the main window class name

// Forward declarations of functions included in this code module:
ATOM                MyRegisterClass(HINSTANCE hInstance);

//INT_PTR CALLBACK    About(HWND, UINT, WPARAM, LPARAM);

//Custom Application Function Forwrd Declarations
void WinControls(HWND);

HMENU hMenu;

int APIENTRY wWinMain(_In_ HINSTANCE hInstance,
                     _In_opt_ HINSTANCE hPrevInstance,
                     _In_ LPWSTR    lpCmdLine,
                     _In_ int       nCmdShow)
{
    UNREFERENCED_PARAMETER(hPrevInstance);
    UNREFERENCED_PARAMETER(lpCmdLine);

    // TODO: Place code here.

    // Initialize global strings
    LoadStringW(hInstance, IDS_APP_TITLE, szTitle, MAX_LOADSTRING);
    LoadStringW(hInstance, IDC_RANKTOOLADVANCED, szWindowClass, MAX_LOADSTRING);
    MyRegisterClass(hInstance); //Generates an instance of a window class

    // Perform application initialization:
    if (!InitInstance (hInstance, nCmdShow))
    {
        return FALSE;
    }
    HACCEL hAccelTable = LoadAccelerators(hInstance, MAKEINTRESOURCE(IDC_RANKTOOLADVANCED));

    MSG msg;

    // Main message loop:
    while (GetMessage(&msg, nullptr, 0, 0))
    {
        if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg))

            TranslateMessage(&msg);
            DispatchMessage(&msg);
        }
    }

    return (int) msg.wParam;

}

Please do note that the setup is the Visual Studio basic setup for the program. Any help is appreciated!

Answer 1

I have done some debugging and figured out it was that the CreateWindowW() I used for the static and edit controls was conflicting with the definition of the window properties.

Since the window was defined by WNDCLASSEXW wcex, I just had to change the CreateWindowW() with CreateWindowExW().

Only new problem is that the static control (and the others) works but not the edit control, which kills the menu.
