int __stdcall StartChannel(int ChannelID);
int __stdcall SetChannalEncode(HANDLE nChID, int streamType);



但无法使用某些功能



but not working some function

int __stdcall RegCallBack();
int __stdcall CB_CardEncode2(unsigned int nChannel,ISIL_ENCODE_DATA *pEncData,void *pContext);
int __stdcall CB_CardReadEncode(unsigned int nChannel,void *pContext);

请帮助我，我在哪里走错了路.
请给我建议.
谢谢

[edit]已排序的代码块-OriginalGriff [/edit]



当编译代码CB_CardEncode2函数未读取时，表示控件未转到CB_CardEncode2
功能；
int __stdcall CB_CardEncode2(unsigned int nChannel，ISIL_ENCODE_DATA * pEncData，void * pContext);

请帮帮我.

谢谢......


Please help me and where am i going wrong way.
please give me suggation.
Thanks

[edit]Code blocks sorted - OriginalGriff[/edit]



when the compile the code CB_CardEncode2 function not read means control not goes to CB_CardEncode2
function;
int __stdcall CB_CardEncode2(unsigned int nChannel,ISIL_ENCODE_DATA *pEncData,void *pContext);

Please help me.

Thanks...............

推荐答案

FILE *P=fopen("c:/Record/TP.txt","w");


我认为这些路径分隔符不起作用.尝试使用''\\''.


I don''t think these path delimiters will work. Try ''\\'' instead.




也许是愚蠢的问题，但是您是否检查/更新了DLL的DEF文件?

Sasa


maybe stupid question, but did you check/update DEF file of your dll ?
