   [code]
   完整的代码有近 2000行
   
   我就把这个这个控件部分的代码发上来
   
   大家帮我分析一下吧
   
   这个控件在另外一个窗口中，以InitDialogBox5(hwnd)来触发
   
   /*------------------------------------------------------------
   control 5
   ------------------------------------------------------------*/
   
   static DLGTEMPLATE MyDlg5 =
   { WS_VISIBLE | WS_BORDER | WS_CAPTION,
   WS_EX_NONE,
   250, 200, 300 ,200,
   "保存文件",
   0, 0,
   4,
   NULL,
   0
   };
   
   static CTRLDATA CtrlInitData5 [] =
   {
   
   { "static",
   WS_VISIBLE | SS_LEFT,
   20, 50, 100 ,20,
   ID_DISP5,
   "输入文件名:",
   0,
   WS_EX_NONE
   },
   
   { "edit",
   WS_VISIBLE | WS_BORDER | SS_SIMPLE| ES_LOWERCASE ,
   110, 50, 150 ,20,
   ID_EDIT5,
   "",
   0,
   WS_EX_NONE
   },
   
   { "button",
   WS_VISIBLE | WS_TABSTOP | BS_DEFPUSHBUTTON ,
   80, 120, 50,25,
   ID_OK5,
   "确定",
   0,
   WS_EX_NONE,
   },
   
   
   { "button",
   WS_VISIBLE | WS_TABSTOP | BS_DEFPUSHBUTTON ,
   170, 120, 50 ,25,

   0,

   for(i = 5, j = 0; j<10; i++, j++)
   { savename2[i] = savename1[j] ;}
   printf("savename2's length:%d\n",strlen(savename2));
   
   m = strlen(savename2);
   
   for(i = m,j=0 ;j<4; i++, j++)
   { savename2[i] = savename3[j];}
   
   
   printf("savename:%s\n",savename2);
   if(fork() == 0)
   { if(execl"/bin/cp", "cp","/home/example/myexample/bmpdisp512/00.jpg",savename2, NULL) < 0 )
   perror("execl error!");
   printf("this is a test\n");
   exit(0);
   }
   
   DestroyAllControls(hDlg5);
   EndDialog(hDlg5, wParam);

   break;

   EndDialog(hDlg5, wParam);
   break;

   }
   break;
   
   case MSG_CLOSE:
   
   DestroyAllControls(hDlg5);
   EndDialog(hDlg5, wParam);
   PostQuitMessage (hDlg5);
   break;
   
   default:
   return DefaultDialogProc(hDlg5, message, wParam, lParam);

   return 0;
   }
   
   static void InitDialogBox5(HWND hDlg2)
   { MyDlg5.controls = CtrlInitData5;
   DialogBoxIndirectParam(&MyDlg5, hDlg2, MyDlgProc5, 0L);
   }
