Android Question [SOLVED] Read all the .jpg files from a remote folder

[desof]

In what way can I read all the jpg files that are in a certain remote folder?
I think in this Sub you should do it

Public Sub FindImages (root As String) As ResumableSub
    Dim j As HttpJob
    j.Initialize("", Me)
    j.Download(root)
    Wait For (j) JobDone(j As HttpJob)
    If j.Success Then
        Dim str As String = j.GetString
        Dim rb As RegexBuilder
        rb.Initialize
        rb.AppendEscaped("<img").Append(rb.CharAny).AppendZeroOrMore.AppendEscaped($"src=""$).StartCapture
        rb.AppendAnyBut(Array($"""$)).AppendAtLeastOne.EndCapture.Append(rb.CharQuote)
        Log(rb.Pattern)
        Dim m As Matcher = Regex.Matcher2(rb.Pattern, Regex.MULTILINE, str)
        Do While m.Find
            Dim link As String = m.Group(1)
            If link.StartsWith("http") = False Then
                If link.StartsWith("/") = False Then link = "/" & link
                link = root & link
            End If
            Main.urls.Add(link)
        Loop
    End If
    j.Release
    Return j.Success
End Sub

Hmm, this may be of some help to you. With just a small change of code this should do exactly what you are looking for...

I have watched the 30 minutes and it has nothing to do with what I am requesting.
I just want to get a list of images from a remote folder

you need a script to display the files?

<?php
$alledateien = scandir('files'); //Ordner "files" auslesen
 
foreach ($alledateien as $datei) { // Ausgabeschleife
   echo $datei."<br />"; //Ausgabe Einzeldatei
};
 echo "ende";
?>

What do you mean with a remote folder? Is this a FTP server? SMB?

In your example you helped me you have a link on line 39 of the Main
https://www.b4x.com/android/forum/t...sing-when-the-slider-is-on.95779/#post-604705 (# 2)

OK!

Wait For (CallSub2(Starter, "FindImages", "https://www.b4x.com")) Complete (Success As Boolean)

NOT FOUND

Wait For (CallSub2(Starter, "FindImages", "https://www.desoft.com.ar/sancrisapp/fotos")) Complete (Success As Boolean)

and I change the link to direct to my server and it does not work because it does not read the images.

Attached I capture my image

as i can see you have a bunch of images in your ftp that you want to download them all into your android device ?

if yes then you need to create a php file to read those files in a url look at the replay above for php code

then in b4a you should get this php content strings to a list and use okhttp to download each item based on your website url

Please note that CallSub2 does not return a ResumeableSub Object!

So it can not be used in the way you are trying.

Learn how Resumeable Subs works. Watch the Video posted by @Peter Simpson in #2 above.

This code read the images from a index.html file, like this:

 <!DOCTYPE html>
<html>
<body>

<img src="1.jpg">
<img src="2.jpg">
<img src="3.jpg">
<img src="4.jpg">
<img src="10.jpg">
<img src="20.jpg">
<img src="myimage27.jpg">
<img src="myimage26.jpg">
<img src="myimage25.jpg">
 
</body>
</html>

If you create a index.html with the names of your images (1.jpg, 10.jpg) and put the file in the folder, the code will read the images and show it in the slider.

thank you very much that's what I was missing so that my images can be read.

Please note that CallSub2 does not return a ResumeableSub Object!

CallSub returns whatever the target sub returns. So if the target sub returns a ResumableSub then it is fine to call it like this.
