D duhai_lee Unregistered / Unconfirmed GUEST, unregistred user! 2005-07-11 #3 pchar 和string 不是一回事， 你最好在vb中用安全的方式获得。 或者把delphi的MyTest方法返回值改为 string， 在library的第一个uses中写上sharemem 。

G gooodlife Unregistered / Unconfirmed GUEST, unregistred user! 2005-07-11 #8 怎么有时候VBA中调用返回值有问题<br><br>从你这句话大概可以看出。接口声明和 VBA中调用都应该是没有问题的吧.<br>如果有问题我觉的不会取得正确的返回值吧..<br><br>是不是你的DLL计算代码有问题呢？
