关于 CreateWindow

WNDCLASS wc;wc.style= CS_HREDRAW | CS_VREDRAW ;wc.lpfnWndProc= (WNDPROC)d3d::WndProc; wc.cbClsExtra= 0;wc.cbWndExtra= 0;wc.hInstance= hInstance;wc.hIcon= LoadIcon( 0 , IDI_APPLICATION );wc.hCursor= LoadCursor( 0 , IDC_ARROW );wc.hbrBackground= (HBRUSH)GetStockObject( WHITE_BRUSH );wc.lpszMenuName= 0;wc.lpszClassName= "dx_IceFairy ";if( !RegisterClass( &wc ) ){::MessageBox( 0 , " Register class failed " , 0 , 0 );return false;}HWND hWnd = 0 ;hWnd = ::CreateWindow("dx_IceFairy" , " dx-icefairy " ,WS_EX_TOPMOST ,300 ,200 , nWidth , nHeight , 0 , 0 ,hInstance , 0 );if( !hWnd ){::MessageBox( 0 , " CreateWindow failed " , 0 , 0 );return false;}

 

函数CreateWindow()其中第一个参数是 类名 ， wc.lpszClassName = "dx_IceFairy"; 这个名字中不能出现空格 如果出现空格会导致创建窗口失败，但是编译能通过。。。
