SetPictureName(lpszPictureName,"WINDOW2","PLKZ-RO2.Pdl"); //Return-Type: BOOL

最佳答案

long a,b;                                                              //定义两个长整型数据变量
a=GetLeft(lpszPictureName, "GYBBPQ1")+30;       //获得GYBBPQ1画面X轴位置，再加30
b=GetTop(lpszPictureName, "GYBBPQ1")-20;        //获得GYBBPQ1画面Y轴位置，再减20
SetTagPrefix(lpszPictureName,"WINDOW2","#4高压泵频率."); //画面窗口"WINDOW2"中的变量都加前缀名称"#4高压泵频率."      //Return-Type: BOOL
SetPictureName(lpszPictureName,"WINDOW2","PLKZ-RO2.Pdl"); //画面窗口"WINDOW2"指向画面"PLKZ-RO2.Pdl"                   //Return-Type: BOOL
SetPropWord(lpszPictureName,"WINDOW2","Top",b);//设置画面窗口"WINDOW2"的Y轴的位置为变量b                                      //Return-Type: BOOL
SetPropWord(lpszPictureName,"WINDOW2","Left",a);//设置画面窗口"WINDOW2"的X轴的位置为变量a
//SetTagSDWord("XP",a); //Return-Type: BOOL
//SetTagSDWord("YP",b);
SetVisible(lpszPictureName,"WINDOW2",1);            //设置"WINDOW2"画面可见  //Return-Type: BOOL
