Android Question Use Variables In Directory String

[SpinBower]

Hi, I have a login form that when the login button is clicked it checks if that user exists. What I need is to use the Username variable in the directory for the list command. Here is my code:

Sub Globals
'These global variables will be redeclared each time the activity is created.
'These variables can only be accessed from this module.
Dim Username As EditText
End Sub

Sub Login_Click
FTP.List("/public_html/users/Username.txt")
End Sub

Sub FTP_ListCompleted (ServerPath As String, Success As Boolean, Folders() As FTPEntry, Files() As FTPEntry)
    Log(ServerPath)
    If Success = True Then
    If manager.Enabled = True Then
        RemoveViews
        Activity.LoadLayout("main2")
    Else
        RemoveViews
        Activity.LoadLayout("main")
    End If
    End If
End Sub

Try

FTP.List("/public_html/users/" & Username.Text & ".txt")

Anything I type in returns true when i use your code. Why is this?

 

[stevel05]

I don't know, it's a simple concatenation of the contents of Username.text.

Try putting it into a string first and seeing what's being sent:

Dim FTPString As String = "/public_html/users/" & Username.Text & ".txt"
Log(FTPString)
FTP.List(FTPString)

Ok so if I don't even put anything in the field it says that "/public_html/users/.txt" exists. I have no idea how that works!

How about if you set it as a string

FTP.List("/public_html/users/.txt")

I figured it out. I just try to download the file and if it fails then its not there.

ftp.list returnes an array (or list or something) of files in the specified folder. So if you check this list aber ftp.list you´ll find no files there i suppose....

Specify an exiting folder ("/path/to/userfiles/"), get the list with

filelist = ftp.list("public_html/path/to/userfiles/")

and iterate through it...

Please note: ftp.list is NOT a fileexists or folderexists.

See example from margret here.

I figured it out. I just try to download the file and if it fails then its not there.

And if the filesize is 1234GB then you let the user download this while just to know whether it exists or not?? LOL

The text file only has user data so it can never be over a 500kb. Also, if they try to download "thfhhvh.txt" they can't, because it's not there.
