hi i worked the above first link like "Disable Special Keys in Win App C#[^]". i got one error for running time. The error is .

CallbackOnCollectedDelegate was detected
Message: A callback was made on a garbage collected delegate of type 'AppsNet!AppsNet.frmMain+LowLevelKeyboardProc::Invoke'. This may cause application crashes, corruption and data loss. When passing delegates to unmanaged code, they must be kept alive by the managed application until it is guaranteed that they will never be called.

broadcast is send message to all client at that time through client ip and port number..
i want only send the message to random of client

Hi, thank u for your reply, again i explain my problem... i have one server with ipaddress and port. The server running this location. But lot of client connect with this server.
for example when i connect to server that time i send message so, server listener getting that message and the write as stream(networkstream). Some case the server send message to client. (The server have one thread running and getting value from database)
more than one client connected with server..
"How to write the correct message with correct client... ) exmple
Database design
client 1 welcome c1
client 2 welcome c2

using only textchanged event becz...when user enter the value in text box then automatically change in amount in lable box. so, this is scenario not in use lostfocus event..
