我正在使用project function创建一个dll.有些功能正在运行，例如

i am creating a dll using project function.there are some function are working like

int __stdcall StartCard(); 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); void WriteBareStreamV1(unsigned int nChannel,unsigned char cDataType,void* pBuffer, unsigned long lBufSize); int WriteBareStream(unsigned int nChannel,ISIL_ENCODE_DATA *pEncData); void WriteBareStreamV(unsigned char cDataType,void* pBuffer, unsigned long lBufSize); //void WriteBareStreamV(unsigned char cDataType,void* pBuffer, unsigned long lBufSize); void WriteBareStreamA1(void* pBuffer, unsigned long lBufSize); void WriteBareStreamA(unsigned int nChannel,void* pBuffer, unsigned long lBufSize); //void WriteBareStreamA(void* pBuffer, unsigned long lBufSize); //ISIL_Card_StartCapEncode(HANDLE hChannel, bool bSub = false); //void OpenFile1(DWORD strFileName); int __stdcall StartRecording(int nChannel,DWORD strfileName);

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 ? Sasa
