Win 32 GUI c++ .bmp The image is not showing - c++

Question

I was actually following a tutorial. I really want to get an answer because I will need to add icons to the window down the line. Getting images to show in the window would be the first step.
Sorry for some reason the update I added did not go through before. My solution is geared towards Unicode.
The corrected updated file is below :
#include <windows.h>
#include <commctrl.h>
using namespace std;
LPCWSTR szClassName = L"myWindowClass";
HWND hLogo;
HBITMAP hLogoImage;
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
void loadPictures();
void parentControls(HWND);
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int icmdshow)
{
HWND hWnd;
WNDCLASSW wc = { 0 };
wc.style = 0;
wc.lpszMenuName = NULL;
wc.lpszClassName = szClassName;
wc.lpfnWndProc = WndProc;
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1);
wc.hInstance = hInstance;
wc.hIcon = LoadIconW(NULL, IDI_APPLICATION);
wc.hCursor = LoadCursorW(NULL, IDC_ARROW);
wc.cbWndExtra = 0;
wc.cbClsExtra = 0;
if (!RegisterClassW(&wc))
{
const wchar_t Error01[] = L"Register Issue To Check On : "; /// Notice this
const wchar_t Error01_Caption[] = L"Error 01";
MessageBoxW(NULL, Error01, Error01_Caption, MB_OK | MB_ICONERROR);
return 0;
}
LPCWSTR parentWinTitle = L"My Window";
hWnd = CreateWindowW(szClassName, parentWinTitle, WS_OVERLAPPEDWINDOW | WS_VISIBLE, 100, 100, 250, 200, NULL, NULL, NULL, NULL);
if (hWnd == NULL)
{
const wchar_t Error02[] = L"Window Creation Issue To Check On : ";
const wchar_t Error02_Caption[] = L"Window Creation Issue To Check On : ";
MessageBoxW(NULL, Error02, Error02_Caption, MB_OK | MB_ICONERROR);
}
ShowWindow(hWnd, icmdshow);
UpdateWindow(hWnd);
MSG msg = { 0 };
while (GetMessageW(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessageW(&msg);
}
return 0;
}
LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
switch (message)
{
case WM_CREATE:
loadPictures(); /// Must be called first, Calling the Images function in Create
parentControls(hWnd);
break;
/* case WM_COMMAND:
switch (wParam)
{
}
break;
*/
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProcW(hWnd, message, wParam, lParam);
}
return 0;
}
void parentControls(HWND hWnd)
{
hLogo = CreateWindowW(WC_STATICW, NULL, WS_VISIBLE | WS_CHILD | SS_BITMAP, 70, 25, 100, 100, hWnd, NULL, NULL, NULL);
SendMessageW(hLogo, STM_SETIMAGE, IMAGE_BITMAP, (LPARAM)hLogoImage);
}
void loadPictures()
{ /// bmp image save in file with main.cpp
LPCWSTR myBmp = L"bitmap1.bmp";
hLogoImage = (HBITMAP)LoadImageW(NULL, myBmp, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);
}

Answer 1

case WM_COMMAND:
switch(wp)
{
}
break;
parentControls(hWnd); <--- never gets here
loadPictures(); /// Calling the Images function in Create
break;
parentControls and loadPictures are never reached in this switch statement.
loadPictures should be called first.
Remove the two lines, put them in WM_CREATE as follows:
case WM_CREATE:
loadPictures(); /// Calling the Images function in Create
parentControls(hWnd);
break;

Answer 2

Someone told me the answer should be here instead of updated above. I am sure I will be made aware that it is wrong if I add it here. I figure that is why the updates didn't take when I tried them before in the original post above. Either way the update/Answer is below.
#include <windows.h>
#include <commctrl.h>

wc.hInstance = hInstance;
wc.hIcon = LoadIconW(NULL, IDI_APPLICATION);
