Rich textbox and string differing

Question

Hi All,

First question, I am reading a serial port and putting output to a string,
but the string is blank, however if I stick a message box in, it causes enough of a gap to allow the text to appear in the string.  I am using a delay based on the length of the expected reply. 
The line of code that appears is reply = rtbIncoming.text.
rtbIncoming.Text has a string in it from the device.  Is it because of seperate threads the reply in the text box appears on one thread, there is not enough of a delay for it to get from the comms thread to the UI thread?

Answer 1

In this case you have to implement security logic, the .Net provides an entire API  System.Security, you can create a permission set that determines rule of messages transactions 

Answer 2

I mean every outgoing mail of a company (mail from a internal network to outside the network)

Answer 3

What do you mean by outgoing mail, do you mean from example a spam?

Answer 4

Thank you very much for your answer!

Probably I should explain a little bit more about the functionality I would like to implement. Basicaly I would like to check every outgoing mail. Therefore I would like to
1. stop the smtp queue
2. wait for messages
3.check these messages (allowed or unallowed and probably remove some of them)
4. Start the smtp queue, so the messages can be send

Answer 5

If I well understand your question you're using a Message queue object then you can do

MessageQueue mqueue = new MessageQueue();
            //This method will make the message queue in a standby state for any message
            IAsyncResult Async = mqueue.BeginReceive();

            //TO do perform you code here

            //This method
            Message Recived = mqueue.EndReceive(Async);
           
            //close the message queue
            mqueue.Close();
It's better to do that asynchormously
