qtimer in console application

[JeanC]

Ask your debugger. It's likely you run out of memory as you probably need twice as much memory as the file you are copying.

I haven't gotten around to working with the debugger yet, I only use qDebug().

Honestly I don't see where I corrupt memory. That QByteArray will be destroyed each iteration because it goes out of scope won't it?
Please show me why this will crash / corrupt because I don't understand.

Good time to start then.

That's why you need a debugger. It's meant to help you and not to provide entertainment in your free time.

I'm not your debugger.

not to provide entertainment in your free time.

This is uncalled for.

This is uncalled for.

Let's see....

1. I'm spending my free time to help you
2. You are sitting in front of a computer with the problematic and crashing code
3. Instead of using a debugger as suggested you complain about me being "unfriendly" and providing "shitty remarks"
4. You want me to help you, which requires:

• me to ask you for the complete code
• me to run your code under a debugger to see why it crashes (assuming it does crash at all)
• me to explain to you why your code crashes
• you to understand and hopefully to correct the problem
• optionally you to complain the code still "doesn't work", then me to ask about a debugger, you to complain about shitty remarks and so on...
• eventually you to run to your boss/teacher/friend/whatever to gloat that you fixed the code

If you consider (1) and (4) I would be spending my free time waiting for you to provide code and then being "entertained by a debugger" while you whine about unfriendly people not wanting to do your work for you. If you don't want to use a tool then don't use it, it is your problem. You can be sitting in front of this code for ages and eventually maybe you will figure it out but then why don't you just spend ten seconds and let the debugger tell you where the code crashes? No time for whining, that's true, but at least the job gets done.

You can either invest your time to learn how to fix such problems or continue living in dark ages hoping somebody will tell you what you did wrong. This was the reason for saying what I said, I didn't want to offend you. The point is you have to provide information so that I can help you. Either you invest your time and evolve or you don't invest your time and stay behind.
