View 2 Repliesim trying to let users login to an application i created in vb.net using the user table of the application's database in mysql i heard that The usual way to do this is to have just one MySQL user called "[my_app_name]" with the relevant permissions. Then my application uses it's own user table to control access to the application, and the one MySQL user to access the database.
View 2 RepliesI'm working on an application in VB.NET that has to connect to a MySQL database and FTP. How secure is it if I used it in an application that I gave to other people. E.g. if I was to let other people use this application would they be able to find out the MySQL and FTP connection details through intercepting packets or something like that? If that's the case how can I work round this? Also, part of my application is an uploader for users to upload files, is FTP secure for that or are there better alternatives ways in doing that? My server is a Windows Server 08 if that makes any difference.

I'm Using Visual Studio 2005 and Mysql Database to create a windows application. The datagrid displays all the records. Since I don't know how to directly update from datagrid, thats why I have used textboxes for the respective datagrid fields. A load button is provided which on clicking puts the data on the respective textboxes. The data can be edited in the textbox. Problem is that I can't save this edited or modified data back into dattabase.

View 1 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).

What i have going on, is i have a MySQL connector as a resource on my application, and im basically trying to connect to my MySQL server, to either a) register a new account, or b) check that the account exists and they are premium, and login, Now what i have run into problems with is: My MySQL Database Name has a _ in it which VB is not allowing for some strange reason.
The code i am using is below
Imports MySql.Data.MySqlClient
Public Class Form1
Function UpdateRecord(ByVal query As String) As Integer
[CODE]...
How i can allow the _ into the application, because the only databases that don't have a _ in the user or dbname are a) Paid ones which i DO NOT have the money for or self hosted ones, i cannot leave my computer on 24/7
