View 1 Repliescreate a chat room? My current hosting is a linux server with mysql. I want to make a client that can connect to the database.(already done) and if the user exists, to open a chat form. I want this to be multithreaded, that way I can have up to 500 people chatting with each other at the same time, from different locations. (realistically will usually be around 50)I have found some winsock type examples, but I dont understand how I can adapt that to work with a linux server... Can anyone help give me examples? I guess I basically want an IRC.(Which I dont know how to implement.)

View 1 RepliesIs there any way to build a web based chat room application by using VB.NET as behind code and put it with ASP.NET on the web so users can login the account and start to chat without keep refreshing the browser or frame and have a real time transaction, I know that I have to use .NET.Socket namespaces, but don't know exactly how. I have seen many examples of windows based applications, but I need to know how to put it on the web.
View 5 RepliesHow would I create a multi-tcp chat room. Im having trouble handling them. I know you can store the connections as arrays or store then in hash tables. Is there a better way to data to a specific connected client. My way was to just broadcast the message to all the connected with the clients name (EX: Client1||MessageHere) || is the split. The client reads the message and sees if client name matches if it does then it will display it other then that it will not. I found out that my server was sending out useless data with this method. So is there a better way to handle/Send messages to a specific client?

View 2 RepliesI've run into another road block while programming my game. The problem is that when a player types North in room "Crash Site" They get the description of traveling to the next room "In Trail" as well as the description of traveling to the next room after that, "Deeper In Trail" before having to type north again. I've looked over the code several times, but can't find the problem....the conditions seem to be fine, but I'm guessing that's where the problem is..
Code:
ElseIf LCase$(txtInput.Text) = "go north" And Room = "Crash Site" Then
Room = "In Trail"

How to make a chat program. Well I just copied code in and the program worked. I can send a message to the server and it sends it back just fine. But I can only send a message once. If I try to send another message I get an error and it says this "A first chance exception of type 'System.Net.Sockets.SocketException' occurred in System.dll" then it "No connection could be made because the target machine actively refused it 127.0.0.1:500".
Here is the link to the tutorial and code: [URL]
I am developing a chat application using online connection to a mysql databbase. But i am facing a problem. After 10 minutes, MySQL closes all the chat connections because of the 600 seconds timeout (has been set by the host service i am using). I don't understand why is that happening cause every piece of my code which needs data from the database opens and closes the connection (i mean that it dosn't maintain the connection after the query's execution). If i .close() and .dispose() the connection, it still appears in mysql at sleep mode (it terminates only if i exit the program).

I have a simple chat program i have made, it works but with a few errors.
1st if it can't find the physical pc it is trying to connect to it crashes.
2nd if it finds the physical server but not the program (server) running it says "the computer actively refused the connection on IP/Port" and then crashes.
Code for connect button:
IP = txtboxip.Text
Port = txtboxport.Text

Im using the code from [URL] as a starter, most of the code is the same. the chat system works fine but on the client a added a disconnect button "clientSocket.Close()" and as soon as i click that i get errors, on the client, this is the code...
Private Sub getMessage()
For infiniteCounter = 1 To 2
[CODE]...
And this line...
serverStream.Read(inStream, 0, buffSize)
gives me "Unable to read data from the transport connection: A blocking operation was interrupted by a call to WSACancelBlockingCall."
Now im talking the server, after the client clicks disconnect or closes by task manager, looses connection, etc the server crashes and gives me.
So, in another related post, i got the chat to send to a java server, cool.Now, it's a matter of sending it back to VB.on the server side of things, (in java), I am using the following
JAVA

ObjectOutputStream oos = new ObjectOutputStream(mySocket.getOutputStream());

I'm running this on Microsoft Visual Basic 2008 I want to make a program with 2 forms, one with buttons, the other that will just hold picture boxes, which are created when those buttons are clicked. Once those picture boxes are placed on the second form, I want to be able to drag and drop them to move them anywhere on that second form.
I have it "working" as of right now, but it's really glitchy. Almost as if it can't keep up with my mouse movement. But I'm not moving THAT fast so I can only assume that something is wrong.The buttons work so I won't post that code here but the following code is for the second form and what I'm using to control the picture boxes.
Public Class Form2
Private counter As Integer
Private boxCounter As Integer
Private list As New ArrayList

Right now I have checkboxes on my form, and depending on what check box I check, the value of it gets put into a text box. So if I check "Right Eye", the texb ox below it gets "Right Eye" placed there.
I would like to do away with the check boxes and instead have a new form pop up with a list of words that gets populated from a table. Is it possible to be able to drag and drop these words into a text box? I guess I could use a List Box control for that but I'm unsure how to implement drag and drop. Maybe be able to multi-select words and then drag them all to a certain text box.
I'd like to have give the user the option of adding and deleting words from that form as they see fit, so could I just let VS do that for me by dragging the datasource onto the form and have it create a bindingnavigator or should I do it myself?

View 2 RepliesAn order can have many OrderDetails, and a Product can be on many different orders. The OrderDetail table just has the OrderID and productID, so there is essentially a many-to-many between order and product).I have a form for the user to enter a new order. I want to have an unbound box that contains the names of all the products, and to be able to drag these names into a box under the order, to add a new OrderDetail record using the productID of the dragged order along with our orderID.
View 1 RepliesI am having trouble with a socket client application written in vb.net using Visual Studio 2005. The client connects to a C language socket server that is running on OpenVMS. The problem that I have is that when the server sends a packet, the client does not receive the last byte (of every packet!). I can dump the packets on the network and the data is all there. My current solution is to keep my socket messages short (247 bytes) and send one extra byte past the end of my data.
I would like to include more information in my messages and I cannot find a way to make this work. If I knew 100% how long the packets will be on the network, I could work around this by including an extra byte in just the right places. However, I don't want to make any assumptions about the length of the packets.
Here is a sample of my client receive code:
Private Sub ReceiveMsg()
Dim nTotalBytes As Integer
Dim nNumBytes As Integer

I am dragging and dropping data from a combobox to a datagrid. I'm using VS2010 VB for a windows app. My problem is that the DragDrop event for the datagrid gives x,y mouse positions that are relative to the physical screen that I am using, not the datagrid. So when I use hittest to calculate the row and column the result is out of the bounds of the datagrid. If I manually drag the form around the physical panel, the x,,y coordinates on the dragdrop event chage accordingly. This is really strange.
View 2 RepliesScenario:I am attempting to perform some work on files (rename/delete) in folder, usually in a network location. Because the location of products folder is not critical, it's rarely ever in the same place on different networks. A simple shortcut on the client machine is all that's required from the client perspective and the rest of the product is self contained on the server somewhere. To run the 'fix' my small application will perform quickly and easily, I need to parse the path held in the target box of the .lnk. Then perform ifexists for a specific file and then do my renaming/deleting.
To keep it as simple as possible, the end user should just 'drop' the shortcut onto my form then click 'fix'.The problem: How in the heavens can I retrieve the target location from the .lnk into a string without windows scripting host?
Make a folder, based on an input file - example :
You have a file named Movie1.avi on your desktop, u open up the program (that I want to make) and then simply drag drop that file into a box area, and then the program will create a folder, with the same name as the input file, but without the extension (folder name Movie1) and then automatically put that file into the folder it just created.
The new folder will be created in the same dir as the input file.
Multiple file support - is NOT needed.
I know how it will be done, but I don't know the code..
