c#中是这样写的 [dllimport( "sdtapi.dll ")] public static extern int sdt_startfindidcard(int iportid, ref int puciin, int iifopen); 我给写的vb6.0中 private declare function sdt_startfindidcard lib "sdtapi.dll " (byval iportid as long, byval puciin as long, byval iifopen as long) as long 是不是哪个地方有写错了呢~~请大家指教我一下~很急,谢谢
private declare function sdt_startfindidcard lib "sdtapi.dll " (byval iportid as integer, byref puciin as integer, byval iifopen as integer) as integer
