I would expect this to be problematic because you're posting
the restore which IMO will not get processed until after you
have tried to being it to front.

You can if you right click it's TaskBar Icon and play with it.

The problem is that you're confusing Windows with respect to
the actual window state by minimizing a minimized window or
restoring a restored window.

Bob is correct that you need to use IsIconic and that you're
calling it with the wrong HWND. IsIconic doesn't work with
child windows so you need to call it on the Application's
Handle.

Once you get the Target HWND, add this:

    HWND hWnd = reinterpret_cast<HWND>( ::GetWindowLong(TargetHwnd, GWL_HWNDPARENT) );
    if( IsIconic(hWnd) ) ::ShowWindow( hWnd, SW_RESTORE );
    ::SetForegroundWindow( hWnd );
