Win32 API CreateWindowW conflicts with Menu Creation - c++

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);
BOOL InitInstance(HINSTANCE, int);
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
//INT_PTR CALLBACK About(HWND, UINT, WPARAM, LPARAM);
//Custom Application Function Forwrd Declarations
void WinControls(HWND);
void WinMenu(HWND);
HMENU hMenu;
int APIENTRY wWinMain(_In_ HINSTANCE hInstance,
_In_opt_ HINSTANCE hPrevInstance,

_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))
{

return (int) msg.wParam;

CreateWindowW(L"Edit", L"...", WS_VISIBLE | WS_CHILD, 400, 155, 100, 50, hWnd, NULL, NULL, NULL);
}
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.
