我自己新建了一个类，生成了许多对象，我想把它们都加到字典中去，但是好像 pDict->setAt("OBJ2", pObj2, rId2); 我不想输入他们的searchkey,字典能自动生成么？

没有searchkey，怎么成“字典”？

liqiang_hust_ca · 发表于 2004-7-21 08:58:59

我不想为每个对象命名啊，太多了，我只是想把他们组织到一起，然后从中间选择出符合条件的对象，返回ID就可以了啊

char name[12];
int n=0;
name[0] = 'A';
//.............loop
itoa( ++n, name+1, 16);
pDict->setAt(name, pObj2, rId2);
//.............

奇怪！！从vc 6.0中拷贝粘贴过来，中文不能正常显示

我热切期望，我刚学ARX，希望能多看到些源代码

wsmm · 发表于 2004-7-31 22:33:19

看到ARX的源代码，我的反映就是不管是什么内容先下了再说。
因为我在学习……
学习中……

中文不能显示，这个问题我也碰到过，只是后来莫名其妙地好了
