Windows 编程的问题,请各位老大救命啊.

#include <windows.h>

           hAccel=LoadAccelerators(hInstance,(LPCTSTR)IDR_ACCELERATOR);  
 
           while(GetMessage(&msg,hWnd,0,0))  
           {  
                       if(!TranslateAccelerator(hWnd,hAccel,&msg))  
                       {

                                   SendMessage(hWnd,WM_PAINT,0,0);  
                                   InvalidateRect(hWnd,NULL,TRUE);  
                       }  
                       else  if(LOWORD(wParam)==IDC_ABOUT)  
                       {  
                                   if(_hInst==NULL)

                       }  
                       break;  
           case    WM_PAINT:  
                       hdc=BeginPaint(hWnd,&ps);  
                       Rectangle(hdc,10,10,50+wsize*50,50+wsize*50);

                       EndPaint(hWnd,&ps);  
                       break;

                       }  
                       break;  
           }  
           return  FALSE;  
}这里有三个问题:  
1.  我做的加速键没有作用.就是按F2键的时候,没有任何反映.  
2.  单击关闭按钮的时候,触发WM_DESTROY后,该应用程序的进程没有结束.再次编译的时候,会出问题,必须手工把该进程关闭(我用的是2000);  
3.在触发IDC_ABOUT后,对话框不能显示出来.  
 
请各位老大指教,不胜感激.
