获取的数据需要通过转换返回，如何转换？谢谢！！！

上电返回代码

int __stdcall ICPowerOn(char *CardNo)
{
	LogTxt(0,"*** ICPowerOn() ***");
    BYTE Cmd[2];
	int Reb;
	int relen;
	char ReceData[2000]={0};
	char ReceLen[1000]="";
	BYTE ReData[1000]={0};
	Cmd[0]=0x49;
	Cmd[1]=0x30;
	Reb=SendTrackCmd(ComHandle,Cmd,2,ReData,&relen,200,2000,2000);
	char Rece[2550]="";
	CharToHex(ReData,relen,ReceData,TRUE);
	sprintf(ReceLen,"数据长度[%d]",relen);
	LogTxt(4,ReceLen);
	memcpy(CardNo,ReData,relen);
	LogTxt(4,ReceData);
	LogTxt(4,CardNo);
	if (Reb!=OK)return Reb;
	return relen;		
}

处理数据代码

if(FPShareStruct->ParaData[i].FuncNo==FUNC_ICPowerOn)
		  {
		  LogTxt(0,"上电指令");
		  Status1=ICPowerOn(Temp);
		  FPShareStruct->ParaData[i].iResult=Status1;
		  char l_num[20];
		  sprintf(l_num,"Status1[%d]",FPShareStruct->ParaData[i].iResult);
		  LogTxt(0,l_num);
		  char Tmp[1025];
		  sprintf(Tmp,"%d",1);
		  memcpy(Tmp+1,"|",1);
		  memcpy(Tmp+2,Temp,Status1);
		  char Temp_log[2550];
		  memcpy(Tmp+2+Status1,"|",1);
		  //CharToHex((BYTE*)Tmp,Status1+3,Temp_log,FALSE);
		  //LogTxt(0,Temp_log);
		  //sprintf(FPShareStruct->ParaData[i].outData,"1|%s|",Temp);
		  lstrcpy(FPShareStruct->ParaData[i].outData,Tmp);
		  CharToHex((BYTE*)FPShareStruct->ParaData[i].outData,Status1+3,Temp_log,FALSE);
		  LogTxt(0,"66666666666666666");
		  LogTxt(0,Temp_log);
		  LogTxt(0,Tmp);
		  LogTxt(1,"2222222222222222222222");
		  //lstrcpy(FPShareStruct->ParaData[i].outData,Tmp);
		  LogTxt(0,FPShareStruct->ParaData[i].outData);
		  FPShareStruct->ParaData[i].procStat=2;
		 }

传出的数据需要为字符型，十六进制显示为3B 6D 00 00 80 31 80 65 B0 84 01 00 C8 83 00 90 00

用sprintf 转换的话 因为有特殊的字符 00 为null 所以转换后不成功 日志为1|;m| 用memcpy转换后 记录的日志为31 7C 3B 6D 00000000000000000000000000000000 即1|;m 后面的丢失 memcpy(Tmp+2+Status1,"|",1); //CharToHex((BYTE*)Tmp,Status1+3,Temp_log,FALSE); //LogTxt(0,Temp_log); 注释部分打印 记录日志为317C3B6D000080318065B0840100C8830090007C 即正确的数据

但是我把lstrcpy(FPShareStruct->ParaData[i].outData,Tmp);换成 memcpy(FPShareStruct->ParaData[i].outData,Tmp,Status1+3); 打印出来的数据时一样的 但是显示的结果还是错误的

没人呀

你想怎么显示,是把数据按汉字方式显示出来还是显示原始数据,如果数据是汉字的内码,你就把数据赋给一个char*的变量,再显示试试;如果是显示原始数据,直接按数值型转换然后再显示或者按.16进制显示
