文档提供的：<br>int GuestCard(HANDLE ICDev,unsigned char CompanyID[8],int CardNo,unsigned char <br>EDate[12],unsigned char RoomNo[8]);<br>我写的:<br>Function GuestCard(ICdev:longint;CompanyIdChar;CardNo:integer;EDatechar;RoomNOchar):integer;stdCall;external 'SWLRD32.DLL';<br>请各位高手看看我写的对吗。。

也许是cdecl而不是stdcall.<br>要看C有没有DEF文件定义该函数的调用约定.<br>如果没有的话默认应该是cdecl约定的
