... of course it's just a simple example
When I look at the commands regarding POP3 (see also links below), libcurl's functionality seems to be limited here. According to my research so far, even in C/C++ there is no example for retrieving all emails at once without logging into the server for each mail.
Even Stenberg's manual does not provide any useful information here.
After you maintain this topic, you might have a tip for an example in C, C++, PHP or a corresponding link ?

I only provide the access to the libcurl commands.
But ...
you can do multiple curl_easy_perform() after an other.
login should be only done once.
So first get the list of ids, then do a loop with
Code: Select all
ForEach IndexList()
curl_easy_setopt(curl, #CURLOPT_URL, "pop3://pop.example.com/" + str(IndexList()))
curl_easy_perform()
...
Next

Thanks for the info.
Your example shows normal usage of curl_easy. This works for me too (runs in its own thread).
The Problem: Every time you receive a message, a new login is performed (see code below).
Code: Select all
curl = curl_easy_init()
If curl
; Set username and password
curl_easy_setopt_str(curl, #CURLOPT_USERNAME, User$) ; **** Login (every time in loop)
curl_easy_setopt_str(curl, #CURLOPT_PASSWORD, Password$)
curl_easy_setopt_str(curl, #CURLOPT_URL, Url$ + "/" + Str(MsgNum))
...
res = curl_easy_perform(curl)
If res = #CURLE_OK
...
endif
curl_easy_cleanup(curl)
endif
My idea was to log into the server once and then retrieve all emails without having to re-authenticate.
I think when using curl_easy there is no other way to bypass the repeated login...

I see no loop in your code.
The loop needs to be inside your If curl after your settings.
Look in my code snippet above.

That is clear. This shouldn't be the complete code with loop, but just show that a login is required every time you use curl_easy...
but thanks for the info...

Hi HeXOR,
thanks for the information, I know the thread and your code works really fine on windows - good stuff!
I used libcurl because my application runs on Windows and MAC and I didn't find the necessary libs for libTLS for MAC
Furthermore libcurl is part of macOS... and I didn't want to compile the libs myself
So at the moment my program (Pop3) is running fine under Windows/Mac, but from my point of view the performance of
libcurl (curl_easy function) has potential for improvement. That's why I asked here if there is another way for (faster) retrieval of emails.
Maybe I find a corresponding example under C or PHP that I can adapt.

Hi Infratec, could you show me an example of how to monitor the progress of a file download? thanks

Added DownloadProgress.pb
You can use PostEvents to update a main program.

Added HTTP_gzip.pb
To show how a content can be downloaded witz gzip compression to reduce transmission data size.
Since the internal libcurl can not handle the compression, the external libcurl.dll is needed beside the executable.
