View 5 RepliesI 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).
Dim MySQLCon as New MySQLConnection
Dim MySQLCom as New MySQLCom

I've been messing around with my Sql Server all day and i still cant get a remote computer to connect to it. I've looked at various resources but really, i don't know where to properly look.
I've configured my Sql Server Express 2005 from the Sql Server Configuration Manger:
- Started Server Browser
- Enabled TCP/IP
- Changed my Sql Server Properties to Network Service
Then for my connection string in Visual Studio using VB.NET is:
ConnectionString = "Integrated Security=SSPI;" + "Initial Catalog=mydb;" + "Data Source=VAIOSQLEXPRESS;"
I am unsure about my connection string especially my Data Source. May someone tell me how to find my Data source? Or if there is anything I'm missing?
i have made a client and server chat system in VB 2008 with winsock,it's a one to one chat and works perfect fine, but do anyone know how to turn it into a multi-client chat system? Code in below: Here is the code for the server:

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

I need to put a combobox on a form that displays a list of customers.Each customer has a customer number and customer name.I figured out that VB.NET doesn't have multi-column combo boxes so to get around that I was going to query the data and put a tab between the customer number and name for the display members and have the value member be the customer number:
SELECT CustomerNumber AS ValueMember,
CustomerNumber + CHAR(9) + CustomerName AS DisplayMember
FROM Customers
ORDER BY CustomerNumber
This only works partially in that in the selected area of the combobox, the tab between the number and name shows but when you drop-down the combobox, the tab is not preserved.
Why there is no multi-column combobox native to VB.NET annoys me but that's whole other topic.Does anyone have any ideas for a solution to this problem that doesn't involve getting a third-party control?
My vb2008 project is connected ["PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = C:MyProductMyInvest.mdb"]to an access database. The numerous searches and filters are sql select coded. The database has been added using the Data Source Configuration Wizard. My problem is when published and loaded on another machine it fails due to being unable to locate the database. I have tried the configuration alternative of making a copy and not.

View 10 RepliesI have made a GUI for my chat program and I'm going to finish the server stuff later. I am using Emoticons ( ) in both ASCII form and picture form. The ASCII ones work perfectly. I have taken the picture ones and put their pictures on buttons so their click event copies and pastes the picture to the rich text box I'm using for text input, but when i hit the submit button, it doesn't copy the picture.I'm using this code to copy the image from the buttons:
Clipboard.Clear()
Clipboard.SetImage(Me.btnSmi.Image)
Me.rtbIn.Paste()
ive tried making it so it copies the picture from the rich text box but that didnt work. i tried declaring a global variable (imgEmo as image) and the setting the variable = to what ever emoticon button is pushed at the time (click event) and using the following code in the submit button's click event:
Clipboard.Clear()
Clipboard.SetImage(imgEmo)
Me.rtbChat.Paste()
This is the code for my submit button:
rtbChat.Text += ((txtIn.Text + (" --") + (TimeOfDay)))
As a side problem, how do i make it so that every time i hit the submit button it starts a new line and formats the comment like this:
James says: (what ever the message is) --(TimeOfDay)
Kristie says: (What ever her message is) --(TimeOfDay)
I understand that for her answer to be there i need a server and all sorts of other code but i am not interested in that yet. I just need that format.
(Name) says: (string) --(Time)
(Name) says: (string) --(Time)
The name is coming from a separate form, the login form, and it is displayed in the top of my main form as "-- Welcome (Name)". i used the text changes event of the main form to then close the login form. I tried using this line of
'This was a global
Dim strNom As String = Login.txtUrn.Text
'in the submit button's click event
rtbChat.Text += ((strUrn) + ("says: ") + (rtbIn.Text) + (" --") + (TimeOfDay))
strUrn = strNom
This did nothing, in the chat box it returned "says: (message) --(TimeOfDay)".
