Question

在Wincc C脚本中，有字符串引用”i=1000"，如何用变量来替换，以便获得外部变量的值，请问如何解决？

UAHCONNECT c1;UAHARCHIVE a1;int iWater;iWater=GetTagDWord("Water_Select");//Return-Type: DWORD uaConnect(&c1);uaQueryArchiveByName(c1,"Coke",&a1);//Return-Type: BOOL uaArchiveOpen(a1);//Return-Type: BOOL uaArchiveDelete(a1,"Water=1000");uaArchiveUpdate(a1);uaArchiveClose(a1); uaReleaseArchive(a1);uaDisconnect(c1);这里，我想将“Water=1000”，替换成“water=’变量值‘”，如何解决？

Answer 1

可以的,将,"Water=1000"这部分定义一串如:...int iWater;char sWater[256];int vWater;//你的变量...vWater=1000; //你的值sprintf(sWater,"Water=%d",vWater);uaArchiveDelete(a1,sWater);...
