iOS Question Socket with Textwriter

[goehberry]

Hi Everyone,

in b4a i usually this code below

Sub Process_Globals

Dim txt As TextWriter
Dim Socket1 As Socket​

end sub

sub Testing

Socket1.Initialize("Socket1")
Socket1.Connect("192.168.1.168",9100,5000)​

end sub

Sub Socket1_Connected(Connected As Boolean)As Boolean

If Connected = True Then
txt.Initialize(Socket1.OutputStream)
txt.Write(pesan)
txt.Flush
txt.Close
Socket1.Close
End If​

End Sub

ini B4i, i couldn't find the replacement for Textwriter...I tried with AsyncStreamstext and AsyncStreams but it is not working like it should...

Please help guys....

Thank you in advance

It's the same code as B4A. - https://www.b4x.com/android/forum/threads/asyncstreams-tutorial.7669/#content

You should update your B4A code. It is a mistake to use TextWriter / TextReader with network connections (your app will eventually hang).

Hi Aaronk, Thanks I finally made it work...

Hi Erel, my code in B4A was to print to network printer, and it was running okay. But maybe I miss something. Can you please advise what suppose to be the update? Thank you in advance!

You should remove TextReader and TextWriter and use AsyncStreams instead.

Android doesn't allow making network calls on the main thread.
