Invalid parameter passed to C runtime function

Yes it can give a good hint. Start app and see how much it uses.

Does error comes as soon as you start the app or
does it take some time?

Lasith

@mrjj The error oocurs when I click a button which feeds a set of values to a QStringList through 2 for loops!

mrjj

@Lasith
Ok, you might copy a lot around and run out of memory.
is it 32/64 bit app?
how much memory do you have?

Lasith

@mrjj I can not check now :( Its in my office PC Now I am home I will notify you tomorrow! :)

mrjj

@Lasith
Ok, if you copy lists, it might be the reason.
You should show the code.
Using all mem with strings, takes a lot of strings :)

And you're sure those 2 loops aren't actually unlimited? ;-) Better look at how many iterations they do :) You do have to do really quite a lot of iterations to run out of memory!

Lasith

@JNBarchan No the upper limits of the conditions is finite! Any way I will check and see! Plus if its an infinite loop the error message is different as I remember!

This is good to know. But there are finite numbers and then there are other finite numbers. Numbers like, say, 0x7FFFFFFF (2 billion?) as the limit in each loop (I'm understanding they are nested?) will cause a lot of iterations... ;-)

Lasith

@JNBarchan yeah they are nested for loops!
