VS 2008 TCP Server / Client - Client To Send The Server 4 Numbers - Depending On The User's Choice
May 9, 2009how to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])

Jul 15, 2009i have been working on a chat program Server side and client side i have most of the features i was asked to put in but then once i got most of the bugs out i noticed something the server admin could send whispers and alerts to single users but then when you try do do it on the client side it wont work so i looked through it all and found my issue the user list on the client is only a list of the names in server hash table so i was wondering how do i send the hashtable and all of its data E.G. user connection information to the client so that it can send commands to individual users like the server side can
vb
Public clients As New Hashtable()
' This subroutine checks to see if username already exists in the clients
' Hashtable. If it does, send a REFUSE message, otherwise confirm with a JOIN.
[code]....
i tried to send the hashtable over the same method used to send the user names to the client but it cannot convert the hashtable to a string so that wont work so my question is How do i send the hash table to the user from the server then display the username on the client ??
VS 2008 - Api - Using Send Message
May 5, 2009I have another problem regarding send message api cause i didnt find any good info on the net.
First of all Send message has:
Hwnd
Wmsg
Wparam
Lparam
What do those mean exactly ? Hwnd is the main window's hwnd or the child? Lparam and Wparam are pointers? How you get them from an external application? How you set Wmsg to send a string?
VS 2008 - Send Message Freezes App
Jun 5, 2009I have an application that uses SendMessage to send a list of numbers one at a time to a query window in the database we use. The problem is that when SendMessage fills the textbox, then clicks "Query" (hWndQuery) my application freezes up until the query is finished running, which sometimes can take up to 20 minutes depending on the query. Any way to force the program to be responsive after it 'clicks' the query button?
Below is my code - I commented where the program freezes (15 lines up from the bottom):Private Sub Query()
Dim hWndQQ, hWndTextBox, hWndQuery, i, iResult As Integer
Dim sTemp As String
sTemp = ""
bCancel = False

View 1 RepliesVS 2008 Multiple TCP Clients - Send The Data Twice To The Same Client
Mar 18, 2009I have a large class that I built to act as a TCP server for one of my silverlight applications. When a user connects it stores the tcp client into a table for later communication. The problem is that when I send data, with more than one client connected, it loops through both open TCP Clients but some how sends the data twice to the same client.... the other tcp client never receives his data. This isn't a logic issue as I can step through the code and see that it is clearly taking each individual TCP client out of the table and sending it the data. They all use the same port... could that be the issue? And if so how do I make it so that it can connect on one port then transfer to another? I have tried using different computers for connecting but still the most recently connected client receives all of the packets of data.
