Cross-platform Method to Download File

[a_butta]

Hi,
I'm new on this forum, and i don't speack english very well, so i'm sorry for my language and i apologize to you if i mistook the location of the topic.

I would ask you if there's a cross-platform method to download a file through a Http URL using lazarus (not to depend on the OS i'm using).
Thank!

Thank very much!
I installed LNet, but i didn't understand how to use it in according to my aim.
Can you help me?
Thank you!

I always use synapse, where you can simply use:
function HttpGetText(const URL: string; const Response: TStrings): Boolean;

For lNet there are examples in the zip file in lnet/examples/visual/http

Good!
I've only a doubt: do Synapse work either on Win and Linux?

Thanks!

Hi,

A project using Synapse:

http://code.google.com/p/lazsolutions

E.g.:

http://code.google.com/p/lazsolutions/source/browse/#svn/trunk/Demos/LSHTTPSend

(Download, get picture, post in Twitter... etc).

Thanks.

Oops, LazSolutions is cross-platform.

Yes.

[a_butta]

Good! Thank very very much to both.

I have another question and i don't know if i must open a new topic. If i must do, i apologize and do it.

How i can delete a file from a folder using a cross-platform method?

Good work silvioprog. The more examples we can get on these things the better.

Good! thank you!
About the preceding argoument, i downloaded the Synapse zip, but i didn't succeeding in installing the units in order to use them in all projects only adding a uses-clause, without having to put every time the units in projects directory.
I hope i had been clear.
Thank

There is a laz_synapse.lpk in trunk.

i installed it, but i can't use httpsend in uses clauses. It return the classic error
"unit1.pas(8,80) Fatal: Can't find unit HttpSend used by Unit1"
