 Hello everyone, I have the following code that works perfectly without problems When sending the data throughout the network, but I have a problem that I cannot solve And it happens that When a client executes the program, it does Not receive the data from the other clients that are are connected only receives the data When New data Is sent.

Example someone connects And In the listview the information that the other users sent Is loaded because they are online, but If another connects they cannot see that information, what I want To Do Is To wait If a client connects again this I send you the information that Is In the listview

 #Region "Variables"
