VS 2010 Developing A Chat Application Using Online Connection To A Mysql Database?
Mar 4, 2012
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).
Dim MySQLCon as New MySQLConnection
Dim MySQLCom as New MySQLCom
Dim counter as Short
[code]....

I am developing an application on VB.NET 2010, I am planning to make an online activation system, the idea behind is that Whenever someone installs my application, the application presents user an activation form, user will be entering product key, name and email address, and then system will establish a connection to a database which contains all the keys on WEB. So how should I make an efficient program to get rid of that.

I am trying to develop a chat application using Visual Basic 2008. I have referred some articles on the internet like [URL]...rogramming.htm and got the concept of connecting and sending data. But when it comes to real world chat applications, there is user authentication and all that. So I was wondering if it is possible to make my own Windows Live Messenger or Yahoo Messenger!!. I searched web for such a sample or source code, but could not find any. Has anyone here created such an application??

I am able to copy the complete online mysql database to the local ms access database, but the problem is that the local database needs to be emptied before the new data is being copied. And a progressbar needs to display the entire progress. Here is the code what I have now:
Private Sub StartScreen1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim dt As New DataTable()

I am building a database application using MYSQL as the backend. The MYSQL instance will be installed remotely on a share host. I have access to SSL certificates. I'm obviously not looking for any code but, conceptually, how do I go about securing the connection using SSL between my application and the remote MYSQL database?

The variable which holds the Inser Into string, during break point debug gives me this: ""INSERT INTO phpvms_fsspireps(pilotid, code, flightnum, depicao, arricao, route, route_details, distance, aircraft, flighttime, flighttime_stamp, landingrate, submitdate, accepted, log, load, fuelused, expenselist, source,

And this is my code.
Dim conn As MySqlConnection
Dim cnString As String
cnString = My.Settings.constr

the DB spec:
Total DB size: 190,1 MB
Total Tables: 106

i 'm develloping an application that uses a sql server database, in my computer where i'm programming i installed the sql server in the same language of the OS, in the tests of the application everything worked fine. Biut after migrating the db to the main server, the values went crazy.. After some research and tests, i saw that the language of the sql server was in english and that was the problem.
My language settings says that the decimal separator is "," and the agrupment digit it's ".", and the sql server works in the other way "." is the decimal separator and the "," it's the agrupment digit. In my code i was using the CDEC to pass the values to the DB, to solve this i removed the cdec and send the parameter as a string (So if i send 2,33 to DB with CDEC i get 233 if i send the 2,33 string i get 2.33). This works for now, but i don't know if in the future i'll have problems...
