用DELPHI如何调用VC写的DLL(30分)

如题，请用过这个的朋友说明一下在DELPHI里如何做声明

function abc;stdcall 'c:/abc/abc.dll'

能不能说清楚些，<br>function abc;stdcall 'c:/abc/abc.dll'<br>然后把函数ABC如何处理？得到动态连接库里的函数呢

看看Delphi自己带的Windows单元，照着里面的做就OK了

function abc;stdcall 'c:/abc/abc.dll'<br>其中函数abc是abc.dll里面的函数，你必须知道这个函数的作用，<br>然后在Delphi里这样声明之后，在适当的地方调用就行了

DLL调用跟DLL是用什么语言编的没多大关系，调用方法是一样的，只要把函数声明中的参数类型写对了就可以啦。
