iOS Question Can not open file from attachment.

[mrossen]

Hi,

I try to open a file attachment, but when I get the file path in my app it seems to be broken,

I want to save the file in my app folder. Can this be done or do I have to read the file and then save it?

I use this example.

Private Sub Application_OpenUrl (Url As String, Data As Object) As Boolean
    If Url.StartsWith("file://") Then
        Dim f As String = Url.SubString(7) 'remove the file:// scheme.
        Try
            Msgbox(File.ReadString("", f), "")
        Catch
            Log(f)
            Msgbox("Error loading file", "")
        End Try
    End If
    Return True
End Sub

But it ends here

Application_Start
Application_Active
Application_Inactive
Application_Background
Can't end BackgroundTask: no background task exists with identifier 2 (0x2), or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug.

Use Log for debugging.

What is the output of Log(f) ?

Hi Erel

I already have. Line 3 from bottom

Try this:

Dim i As Int = f.LastIndexOf("/")
Dim su As StringUtils
f = f.SubString2(0, i + 1) & su.DecodeUrl(f.SubString(i + 1), "utf8")

Hi Erel,

This works great. Thank you
