Using large data structure for storage!

[jsulm]

@Kushan I tested this code: it does not crash (and I don't see why it should).
As I said you should first debug to see where it actually crashes.
And you still did not say how big your strings are. If they are huge then maybe your app gets out of memory and is terminated by the OS.

@jsulm No this is just a sample the actual QString is very long :(

[jsulm]

@Kushan How long?

[Kushan]

@jsulm actually
QString Test="New,0,0,Instrument1,Order,Buy,100,Amend, Quote"

[jsulm]

@Kushan That's not long.
Please debug you app to see where it is crashing. I'm out of ideas as the code you posted doesn't crash and there is not enough information to tell you why your app is crashing.

@jsulm Thanx alot how to use the debug?

[jsulm]

@Kushan Take a look at http://doc.qt.io/qtcreator/creator-debugging-example.html
and http://doc.qt.io/qtcreator/creator-debugging.html

[Kushan]

@jsulm Thanx for sparing your time

[jsulm]

@Kushan No problem

[Kushan]

@jsulm Actually the error is indexout of bound but I havent declared any size anywhere in my code for all the structures I have used!

[jsulm]

@Kushan Are you accessing list elements using [] anywhere in your code like

QList<QString> list;
qDebug() <<list[0];

?

[Kushan]

@jsulm yes :( But the problem is that I have never declared a specific size but only used size() method in for loops!

[Kushan]

@jsulm Got it solved it was in the textfile that I used to read into the QList because the value I gave is more than the number of elements in the text file that I read!
