Create window form C++ function using MFC or Win32 API

[Pavel_47]

Ok, you are right. Thanks Ovidiu.
Here is a bit of code, that doesn't work:

HWND hWnd = CreateWindow(szAppName, L"title", WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, 0, 0, GetModuleHandle(L"vpi_win32.dll"), 0 );
vpi_printf("Window handle: %d\n", hWnd);
if(hWnd != NULL)
{
BOOL b_ShowWindowRSLT = ShowWindow(hWnd, SW_SHOWDEFAULT);
while(GetMessage(&msg, 0, 0, 0))
DispatchMessage(&msg);
vpi_printf("pass 3\n");
}

Here is CAD console output (vpi_printf):

So, as you can constate, the execution is blocked inside of GetMessage function.
