Connect Excel to work.

At the time of launch, Excel must be open.

By default, the current Excel page becomes active.

Call:

int ires = excel_attach();


If 0 is returned, then the connection is successful.


Example.

Connect the current Excel table and output the number 100.1 to the current position of the marker.


int my_variable;
coutvar << my_variable;
int ires = excel_attach();
if (res != 0)
{
    cout << "No connection to Excel";
    return -1;
}

double dvalue = 100.1;
excel_putnumvalue(dvalue);
excel_detach();
