QBytearray output in single line ?

[benver]

Your English is far better than my French

I do not think your code will compile (e.g. there is no simplified() method in QDataStream and there does not seem to be a closing brace on the while() loop)

What does "c:/qt/essaiqt.csv" contain? Something like this perhaps?

1;3359;3;4;5
1;9952;3;4;5
1;69855;3;4;5
1;3524;3;4;9999

1;3359;3;4;5
1;9952;3;4;5
1;69855;3;4;5
1;3524;3;4;9999

To copy to clipboard, switch view to plain text mode 

What are you trying to achieve?

• For each line, output the largest value in the line (3359, 9952, 69855, 9999), or
• Output the largest value found in "column2" of any line (69855)

Thanks for reply
I would like to put it in one line and find maximum, because if i'm searching maximum on not complete line, it will give me return of each max of each line, thats why i would like to get first on one line then apply minmax et max_element
