[lazzaro2023]

Hi everyone!!!
I have a problem.
Is it possible to implement a procedure that shows me a progress bar while I download a file from the internet?
Can someone help me?

Hello lazzaro2023,
Welcome to the forum.

In the link below, you can find "File download" demo in the Networking category:

I posted a threaded progressbar downloader here:
https://forum.lazarus.freepascal.org/index.php/topic,60314.msg450770.html#msg450770
The actual downloading code is maybe ~150 lines. I couldn't think of a smaller way of writing one.
I've also attached a project to this post. It should get you started

We can try.

Upload to where?
Basics are the same, just easier since a download with a progressbar can be wrong when the source not tell the real size (for such my download switch to a marquee and still tells in how fast it is)
So have your progressbar updated after each chunk you uploaded.

Internet

Since "Internet" is no protocol but for transfers you need a protocol your answer is just .....
So what I showed you in my last post is for the FTP (File Transfer Protocol)
If that is not what you need, be more specific.

Did you download the attachment from Reply #2? I see a big juicy progressbar on the main form.

Thank you for the report. I saw the progress bar in the foreground, but it indicates the bytes read from the read stream buffer, not the bytes actually uploaded to the server. Do you have a solution for this on the client-side program?
