Win32: How to create a ListBox control using the CreateWindowExW() function?

I've been through multiple sites, documents and tutorials and they all say the same, that is, any control is nothing more than a window in Win32's API, hence one is able to use the CreateWindowExW() function to create a ListBox control/window over the main application window.

Though I get the concepts of all controls being windows with different dwStyle, I have a hard time finding out how to instantiate, to say so, the ListBox control.

I encountered a tutorial where a dialog is written to have a LISTBOX specified in its declaration as follows:

// resource.h
#define IDD_MAIN                        101
#define IDC_TEXT                        1000
#define IDC_NUMBER                      1001
#define IDC_LIST                        1002
#define IDC_ADD                         1003
#define IDC_CLEAR                       1004
#define IDC_REMOVE                      1005
#define IDC_SHOWCOUNT                   1006

// .rc resource file
IDD_MAIN DIALOG DISCARDABLE  0, 0, 207, 156

    LTEXT           "times",IDC_STATIC,114,141,17,8
END

And using it in his C program like so:

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {
    return DialogBox(hInstance, MAKEINTRESOURCE(IDD_MAIN), NULL, DlgProc);
}

Now, this I am able to do and fully understand the concepts. Aside, I would like to be able to create and design my main application window to add a ListBox control to. This tutorial example doesn't use the CreateWindowExW() function to create the control, instead, it creates a dialog that will actually be the main application window.

1 - Any clue on how to add a ListBox control to the main window in code?

I thought about creating it while handling the WM_CREATE message.

2 - Is this a good idea?

3 - What is the best practice/approach in this scenario?

In order to dynamically create a control in Win32's you need the following code:

HWND hBtn, hLabel, hListbox, hTextBox;

void InitializeComponent(HWND hWnd) {
    HINSTANCE hInstance = GetModuleHandle(NULL);

    // Adding a Button.
    hBtn = CreateWindowExW(WS_EX_APPWINDOW,
        L"BUTTON", NULL,
        WS_CHILD | WS_VISIBLE,
        327, 7, 70, 21,
        hWnd, NULL, hInstance, NULL);        

    SetWindowTextW(hBtn, L"&Button");

    // Adding a Label.
    hLabel = CreateWindowExW(WS_EX_CLIENTEDGE,
        L"STATIC", NULL,
        WS_CHILD | WS_VISIBLE,
        7, 7, 50, 21,
        hWnd, NULL, hInstance, NULL);

    SetWindowTextW(hLabel, L"Label:");

    // Adding a ListBox.
    hListBox = CreateWindowExW(WS_EX_CLIENTEDGE,
        L"LISTBOX", NULL,
        WS_CHILD | WS_VISIBLE | WS_VSCROLL | ES_AUTOVSCROLL,
        7, 35, 300, 200,
        hWnd, NULL, hInstance, NULL);

    // Adding a TextBox.
    hTextBox = CreateWindowExW(WS_EX_CLIENTEDGE,
        L"EDIT", NULL,
        WS_CHILD | WS_VISIBLE | ES_AUTOVSCROLL,
        62, 7, 245, 21,
        hWnd, NULL, hInstance, NULL);

    SetWindowTextW(hTextBox, L"Input text here...");
}

LRESULT CALLBACK WndProc(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam) {
    switch (Msg) {
        case WM_CREATE:
            InitializeComponent(hWnd);
            break;            
        default:
            return DefWindowProcW(hWnd, Msg, wParam, lParam);
    }
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd) {
    // Declaring, defining, registering and creating window here...
    // Note that each Window/Control has to have its own Message handling function.
}

HWND hListBox; // Handle for list box control

hListBox = CreateWindowEx(
  WS_EX_CLIENTEDGE, // extended window styles
  "LISTBOX", // list box window class name
  NULL,
  WS_CHILD | WS_VISIBLE, // window styles
  7,   // horizontal position
  35,  // vertical position
  300, // width
  200, // height
  hWnd,
  NULL,
  hInstance,
  NULL
);

if (!hListBox){
  // failed to create list box window - take actions ...
}
