write to excel file

hello,

i'm a begginer in Labwindows CVI so excuse me for the poor code.

i've noticed there are a lot of answers for writing to excel file but my problem is not similar.

i read numbers from a sensor into an array and i want to copy them in real time to excel file.

the problem is that i dont know how to extend the range of the rows in the excel automaticly without manually enter the row's number (for example "A1:A10")

here is a part of the program:

double val[]={8.7,9.2,1} ; // example of array of numbers

ExcelRpt_WriteData (rawDataWorkSheetHandle, A1,ExRConst_dataDouble, 1, 1,&val[0]);

ExcelRpt_WriteData (rawDataWorkSheetHandle, A2,ExRConst_dataDouble, 1, 1,&val[1]);

ExcelRpt_WriteData (rawDataWorkSheetHandle, A3,ExRConst_dataDouble, 1, 1,&val[2]);

i've tried to use these type of writing:

A[i]

A[i+1];

A[i+2];

but it didnt work.

i asume there is a more useful way to do it but i dont know how.

i appreciate all the help i can get!
