WINCC CSV文件參數導出/導入

CSV文件參數導出

#include "apdefap.h"

void OnClick(char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName)

{

FILE*  pFile = NULL;

char szFile[_MAX_PATH+10];

char* CC=NULL;

char * F[3]={"F1","F2","F3"};

char * T[3]={"T1","T2","T3"};

char * C[3]={"C1","C2","C3"};

int FF,i;

float TT;

strcat(szFile,"d:\\data.csv");

pFile=fopen(szFile,"w+");//注意如果用“a”代替“w+”則表示，不覆蓋原來CSV文件內容

if(pFile==NULL)

{

printf("\r\nError in fopen()\r\n");

return;

}

for(i=0;i<=2;i++)

{

FF=GetTagDWord(F[i]);

TT=GetTagFloat(T[i]);

CC=GetTagChar(C[i]);

fprintf(pFile,"%d,%f,%s\n",FF,TT,CC);//注意這裏%d和%f中間 有“，”可以使CSV到處和EXCEL格式相同 ！！！重要

}

fclose(pFile);

}
