[?]: WinCC C script for work with an EXCEL sheet

Post by PLC_ITA »

Hello friend's , i need a help from you.

I need to write a C code for open , write a value ,and save an EXCEL sheet

For example :
open a new Excel sheet
write into A1 cell a value
save and close

I know very well a VB but a C i havent a little experience.

In this case i need to write a code in C because i need to insert this into a function already existing.

If is impossible to create a XLS file , also CSV is good

Can you help me ?

thank you in advance

try this one

it's in italian
ORA = now
GIORNO = day
MESE = month
ANNO = year

Code: Select all

#include "apdefap.h"

int gscAction( void )
{

extern float somma29,somma30,somma31,somma56,somma57,somma58,sommaTe;
