GetCertInfo()
works now as it should.
The structure for certinfo was wrong.

Changed all examples to use the new defines:

Code: Select all

#LibCurl_ExternalDLL
#LibCurl_ExternalStaticLib

Updated libcurl to 7.86.0

Added LibCurl_Info() to libcurl.pbi.
Now you can see informations about version and included protocols by simply call LibCurl_Info().

A thing I didn't know:

https://curl.se/windows/microsoft.html

Fixed a bug:

The last parameter of curl_easy_setopt() needs to be a .q

I found this bug during I wrote NextCloud.pbi.
The upload was not possible without .q

At the moment NextCloud.pbi contains:

Code: Select all

Procedure.i NextCloud_GetShares(URL$, Username$, Password$, List ShareList$())
Procedure.i NextCloud_FileExists(URL$, Username$, Password$, File$)
Procedure.i NextCloud_CreateFolder(URL$, Username$, Password$, Path$)
Procedure.i NextCloud_UploadFile(URL$, Username$, Password$, LocalFile$, RemoteFile$)
Procedure$ NextCloud_CreateShareLink(URL$, Username$, Password$, RemoteFile$, SharePassword$=#Null$)
Procedure.i NextCloud_CopyFile(URL$, Username$, Password$, RemoteSource$, RemoteDestination$, OverwriteIfExists.i=#False)

And a demo.

Thank you for that! The NextCloud library is definitely interesting for me!

Posted: **Sun Dec 04, 2022 11:04 am**

I added new procedures to NextCloud.pbi:

Code: Select all

Procedure.i NextCloud_GetShares(URL$, Username$, Password$, List ShareList$())
Procedure.i NextCloud_FileExists(URL$, Username$, Password$, File$)
Procedure.i NextCloud_CreateFolder(URL$, Username$, Password$, Path$)
Procedure.i NextCloud_UploadMemoryToFile(URL$, Username$, Password$, *Memory, Size.i, RemoteFile$)
Procedure.i NextCloud_UploadFile(URL$, Username$, Password$, LocalFile$, RemoteFile$)
Procedure.i NextCloud_DeleteFileOrFolder(URL$, Username$, Password$, File$)
Procedure.i NextCloud_DownloadFile(URL$, Username$, Password$, FileToDownload$, TargetFile$)
Procedure.s NextCloud_CreateShareLink(URL$, Username$, Password$, RemoteFile$, SharePassword$=#Null$)
Procedure.i NextCloud_CopyFile(URL$, Username$, Password$, RemoteSource$, RemoteDestination$, OverwriteIfExists.i=#False)

NextCloud_UploadFile() reads now from the file and don't need additional RAM.
I did this, because uploading a DVD file is to large for the internal RAM.
But I added NextCloud_UploadMemoryToFile() where you can directly upload *Memory to a file.

I also changed the name of the 2 callback procedures to reflect the CURL_OPTION parameter names.

Changed NextCloud.pbi a bit:

Code: Select all

Procedure.i NextCloud_GetShares(URL$, Username$, Password$, List ShareList$())
Procedure.i NextCloud_ExistsFileOrFolder(URL$, Username$, Password$, File$)
Procedure.i NextCloud_CreateFolder(URL$, Username$, Password$, Path$)
Procedure.i NextCloud_UploadMemoryToFile(URL$, Username$, Password$, *Memory, Size.i, RemoteFile$)
Procedure.i NextCloud_UploadFile(URL$, Username$, Password$, LocalFile$, RemoteFile$)
Procedure.i NextCloud_DeleteFileOrFolder(URL$, Username$, Password$, File$)
Procedure.i NextCloud_DownloadFile(URL$, Username$, Password$, FileToDownload$, TargetFile$)
Procedure.s NextCloud_CreateShareLink(URL$, Username$, Password$, RemoteFile$, SharePassword$=#Null$)
Procedure.i NextCloud_CopyFile(URL$, Username$, Password$, RemoteSource$, RemoteDestination$, OverwriteIfExists.i=#False)

I also extended the Demo at the end of the code.

I forgot to add curl_mime_name()

This is fixed now. It is needed for multipart forms.

To show an example I added PaperlessNgx.pbi:

Code: Select all

Procedure.i PaperlessNgx_UploadFile(URL$, Username$, Password$, File$, List TagList.PaperlessNgx_IdNameResultList_Structure(), *Correspondent.PaperlessNgx_IdNameResultList_Structure=#Null, *DocumentType.PaperlessNgx_IdNameResultList_Structure=#Null)

Thanks Unfratec,
That's work well for downloading. I will try now with example

Posted: **Thu Dec 22, 2022 10:02 am**

Hello infratec,
I use you outlookemail.pb and i want to embed an image in the text of the mail . How can i proramm it ?
Thanks in advance

Posted: **Thu Dec 22, 2022 3:18 pm**

1. This question is not libcurl related.
2. I don't use outlook, so I can test nothing.

Write an e-mail in outlook with embedded picture, send it to yourself and inspect the source code of the e-mail.

Maybe this is also useful:
https://stackoverflow.com/questions/670 ... html-email

But it looks that outlook does not accept inline Base64 images (which is the easiest way).
So you need the cid way with additional boundary and the binary image.
And even then outlook may not show it depending if the sender is trusted or not.

Posted: **Thu Dec 22, 2022 5:02 pm**

In fact i don't use outlook to send mail i use my own provider free.fr and curlib but i have modify your outlook.mb like following

#MailServer = "smtp.free.fr:587"

#FROM = "<xxxx@free.fr>"
#To = "<xxx@sxxxxxx>"

#SMTP_User = "xxx@free.fr"
#SMTP_Password = "xxxxx"

I can send outline attachements with

*part = curl_mime_addpart(*mime)
curl_mime_filedata(*part, "index.php")
