自已顶,高手快来!!!
 
路过的大哥们请留下一点痕迹,帮我顶一下吧!!!小弟谢过了!!!
 
再顶一次!!
 
在你的
then
Begin
showmessage('没有插入IC卡');
ClosePort():
Exit;
End;

例如：

st:=rf_authentication(icdev,0,sector);
if st<>0 then
Begin
Application.MessageBox('卡验证密码错误A，请换卡！！！','错误提示3',MB_ICONQUESTION+MB_OK);
st:=rf_exit(icdev);
Exit;
end;

st:=rf_HL_read(icdev,1,block,snr,@databuff,@ssnr);
St:=rf_decrypt(Pchar(EnCardPass),@DataBuff,16,Data1);
if St<>0 Then
Begin
Application.MessageBox('读卡错误，请换卡！！！','错误提示3',MB_ICONQUESTION+MB_OK);
st:=rf_exit(icdev);
Exit;
End
 
你把dll函数声明中的所有String类型换成Pchar类型试试
 
你将你的DLL导出函数检查一下呢，是不是应该将String改为PChar？
 
装了DELPHI6就好了,后来让厂家换了一个驱动程序也就好了.很感谢大家的支持.
