Saving array data to file ?

I am trying to save array data to the end of a file but the file size does not appear to be increasing.

Is it possible to append array data to the file????

I am using .........

mArrdat = FileOpen(mArrFile, FILE_BIN|FILE_WRITE, ';');
if(mArrdat > 0)
{
int p = FileSeek(mArrdat, 0, SEEK_END);

FileWriteArray(mArrdat, mCurrVals, 1, 9);
FileClose(mArrdat);
}

All help appreciated.
TIA

The description for the function mentions this...

....If there is a need to add data to an existing file, it must be opened using combination of FILE_READ | FILE_WRITE.

Perhaps this is the problem?

Thanks so much.
Been staring at it so long that I missed that ;-(

I am sure that is the answer

it is exactly the problem. it's just another example of mql being as retarded as fuck.

if they had their shit together they would have the following bit flags

1 = read
2 = write
3 = append

but in their epic laziness they didn't bother defining the append type, and instead you have to bitwise or the read and write values... or just hard pass a value of 3 which is exactly the same thing.

similarly with the bin and csv type bit flags. they are misleading, and mql is just pure ass and more difficult and unintuitive to use than a real programming language.

Hi Nubs :-))

Take it that you really like mq4 then!
My sentiments exactly but I do think that you was being a little too lenient ;-)

And there was me thinking that it was me being a little too dense (again).
