It looks like you started by copy-n-paste from one of the examples but, when it didn't Just Work, you thrashed about looking for another cut-n-paste code snippet rather than trying to understand why it didn't work.

Stop hacking at your code. Open Qt Assistant, navigate to the "Qt Reference Documentation", then "Tutorials and Examples", then "Network" examples. There are three examples you should study (in order):

• HTTP
• Download
• Download Manager

They all compile, work, and download file(s) with varying degrees of complexity. When you find something in the examples that you do not understand then ask.

Also, read back through this thread, especially the post by Berryblue031.

You wondered what RESPONSE_ERROR the other constants were: user-defined symbolic names for HTTP status codes

Yes, now the file is downloaded. But Am not getting the file with actual size..

Sorry, my crystal ball is broken. Care to give us a bit more information?

Sorry, my crystal ball is broken.

You should really get a spare one :P

Do you know how much crystal balls are now? I can't really afford a spare one.

Gokulnathvc: Here is how to ask your question:

I have am trying to download a {binary/text} {PDF/database/Transylvanian folk remedy} file using HTTP, QNetworkAccessManager and code based on the XYZ example from Assistant. My actual code is:

// my actual code, inside [code ]...[/code ] tags, and distilled down to a small
// compilable example that demonstrates the problem

// my actual code, inside [code ]...[/code ] tags, and distilled down to a small
// compilable example that demonstrates the problem

To copy to clipboard, switch view to plain text mode 

The request is being processed and there I am seeing a signal that the request is done. However, when I save the data my file is not empty but it is also not complete. As you can see every call that generates a true/false status or error code return value is being checked and there are no errors being reported. I have tried other files and {insert what happened differently}. I've also tried other web sites and {insert more evidence you have tried to solve this yourself}.

If I use the example code without modification then the file is downloaded OK. The differences between my code and the example are {insert description here} or:

// more code differences inside [code ]...[/code ] tags

// more code differences inside [code ]...[/code ] tags

To copy to clipboard, switch view to plain text mode 

I have tried {more stuff} with {more results} but I really cannot see what I am doing wrong.

Could someone please provide advice so that I can solve my problem?
