How I do a function C# for i can receive messages from Server Chat in PC and Chat Client in Android device?

In my C # application Chat Client I don`t not know how to do a function to receive messages from the Chat Server in C # and presents them in a TextView Chat Client

I'm programming in Visual Studio in C # using Mono for Android.

The question is... How I do a function for i can receive messages from Chat Server in PC and Chat Client in Android device? When i use Chat Client in windows 7 works good but when i make for a android device i can`t receive mensages from Server Chat to Chat Client.

I think the problem as in public void RecievedMessage and private void UpdateTextbox.

Sorry, my bad english. Thanks your atention.

It looks to me like (one) problem is that you are trying to access text1 as if it is a field or property when it is a local variable declared in onCreate. You either need to push text1 up a level in scope, or grab a new reference to it in RecievedMessage. This is not a problem with Android, specifically, but is a difference with how the code is set up with Mono for Android.

Typically, when working with Winforms in Windows, you'll be working in a partial class with all your controls defined in the designer.cs file as fields. But in your Mono code, you are binding to TextViews instead, and in your OnCreate instead of at instance scope. When you copy/pasted your code, you likely didn't account for that difference.

As an aside, I highly doubt that the user32.dll function you are importing is going to do anything useful on Android. Unless the Mono folks are doing something magical, the win32 API will not be available on Android.
