[C++][Win32]Postavljanje ikone aplikacije

[morando]

Pozdrav svima, ovo je moj prvi post na ovom forumu.

Moj problem:
koristim MVS Express edition (C++) 2010, znači nema resource editor-a a i ne koristim MFC. Sastavio sam minimalnu aplikaciju za koju vas molim ako imate vremena da probate da li funkcioniše kod vas:
main.cpp

#include <Windows.h>
#include <xstring>
#include "resources.h"

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam);
void ReportLastError();

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
	HWND            hwnd;
	HINSTANCE       hinstance;
	std::wstring strClassName = L"TestClass";
	std::wstring strAppCaption = L"TestApp";
	WNDCLASSEX      wndClass;

	ZeroMemory(&wndClass, sizeof(WNDCLASSEX));

	hinstance                      = GetModuleHandle(NULL);
	wndClass.cbSize                = sizeof(WNDCLASSEX);

	wndClass.hCursor               = LoadCursor(NULL, IDC_ARROW); 
	wndClass.lpszClassName         = strClassName.c_str();
	wndClass.hIcon                 = reinterpret_cast<HICON>(LoadImage(
		hinstance, MAKEINTRESOURCE(ID_APP_ICON), IMAGE_ICON, GetSystemMetrics(SM_CXICON), GetSystemMetrics(SM_CYICON), 0));
	if(0 == wndClass.hIcon)
	{
		ReportLastError();
	}
    wndClass.hIconSm = reinterpret_cast<HICON>(LoadImage(
		hinstance, MAKEINTRESOURCE(ID_APP_ICON), IMAGE_ICON, GetSystemMetrics(SM_CXSMICON), GetSystemMetrics(SM_CYSMICON), 0));
	if(0 == wndClass.hIconSm)
	{

	}
	wndClass.hbrBackground         = GetSysColorBrush(COLOR_3DFACE);

	if(!RegisterClassEx(&wndClass))

	}

	DWORD dwStyle = WS_SYSMENU | WS_BORDER | WS_CAPTION | WS_CLIPSIBLINGS | WS_VISIBLE | WS_MINIMIZEBOX;

	int realHeight = clientSize.bottom - clientSize.top;
	int windowLeft = (GetSystemMetrics(SM_CXSCREEN) - realWidth) / 2;
	int windowTop  = (GetSystemMetrics(SM_CYSCREEN) - realHeight) / 2;

	hwnd = CreateWindowEx(
		NULL, strClassName.c_str(), strAppCaption.c_str(), dwStyle,              
		windowLeft, windowTop, realWidth, realHeight,
		NULL, NULL, hinstance, 0);
	if(NULL == hwnd)
	{
		ReportLastError();
		return 0;
	}

	ShowWindow(hwnd, SW_SHOW);
	UpdateWindow(hwnd);

	MSG  msg   = {0};
	while(GetMessage(&msg, NULL, 0, 0))

reources.h

#ifndef resources_HEADER_DEFINED
#define resources_HEADER_DEFINED

#define ID_APP_ICON       (100)

#endif

resources.rc

#include "resources.h"

ID_APP_ICON ICON DISCARDABLE "appicon.ico"

dobijem prikaz ikone u taskbaru i u prozorima ali je nema u levom uglu aplikacije (kod "caption"-a) stoji "default" ikona. Ikonu sam pravio sa IconFX programom, ikona je True color 32bit i ima 3 "images" 48x48, 32x32 i 16x16.
Ne znam koji se qra* događa, oprostite na jeziku ali se batrgam sa ovim već neko vreme, čupam kosu sa glave a ne mogu da nađem u čemu je problem.

Hvala unapred.
