Is this not correct?

Hello friends,

After it appears that cURL is becoming increasingly important and widespread, I am posting some information on the cURL Lib here, which I created with the help of ChatGPT.

https://mybergland.com/fwforum/curl-lib.pdf

Interestingly, I just used this function yesterday as well, but from PHP, to call mod harbour.

I don't like it. It requires a 4 MB DLL! Or am I wrong?

There are many ways to skin the cat.

Both the functions WebPageContents() and URLDownloadToFile() work only on Windows OS.
For Web Applications, we need platform independent tools and CURL seems to be the popular choice.

You have to link wininet.lib from your C compiler.

I never needed of such a function for web applications.

Dear friends,

please can you help me...I try to follow along and was busy reading what I found in our manual folder (fwfun.chm, fwcmd.chm, fwclass.chm,...).
Now I am curios about XImage(), WebpageContents() where could I find out more about these interesting things? Maybe someone would be kind enough to point me to a wiki for these?

Kind regards to all of you and a thank you - also to those who wrote the wonderful documentations ... they are of immense value - as the forum is.
