Server-Client Data Exchange Using MySQL (.Net)?

May 3, 2012

I developed a simple examination system with registration forms. I used VB.Net as the programming language. I haven't tried manual coding for my problem yet.Anyway this is a project for the company from which I am an intern. The plan is to get every client pc to have this examination/registration application and this application will send the personal info and the score to a central database(server pc).I used MySql as the dbms and developed the application on the same machine which means that the Database server I used is only on the local host.

Now I was about to try to implement the application to one client pc(as a beta test) and installed the necessary files(.net framework) and I also installed MySQL Server(and workbench) in the server pc.When I run the application in the client PC it didn't detect/connect to the ServerPC's MySQL server instance and therefore was not able to record the dummy values I input in the client application. Take note I changed the connection string of my app to point to the ip address of the serverPC.

Should I install the MySQL Server(and Workbench) to every ClientPC so that I can create a server instance that uses the REMOTE HOST option and configure it such that it will connect to the SERVERPC's Database?How should I setup the server so it gives access to the application I installed in all clientPCs?

VS 2010 - MySQL Connector As A Resource On My Application - Connect To My MySQL Server

Jun 21, 2012

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

How To Encrypt Output Of MySQL (Dump Files)

Jan 23, 2012

I use this code to create dump files of my database. Now what I want, if possible, is to encrypt it so that when it is viewed in notepad or anything similar, average users cannot read it.

Call isDirectoryExist()
Call createDbBackupName()
Dim myProcess As Process = New Process
Dim strUser As String = "superadmin"
[Code] .....

Of course, if it encrypted, it has to be decrypted before querying the dump file. I have no idea what encryption I can do in vb.net and mysql

I modified my first code
Process.Start("C:/MySQL/bin/mysqldump.exe", " --host=localhost --user='" & strUser & "' --password=1234 """ & strDbName & """ -r """ & strPath & newDBName & """, --cipher /e /a '" & newDBName & "' ")
But the output file contains nothing whatsoever.

MySQL Output Parameter With Asp.net And SqlDataSource Control?

Jul 19, 2011

I'm in the process of switching my application from MSSQL to MYSQL. When I was using MSSQL, I retrieved the last auto increment value via

Private Sub dsImpoundInformation_Inserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles dsImpoundInformation.Inserted
_impoundId = e.Command.Parameters("impoundId").Value
End Sub

[Code]...

ultimately, I'm just trying to get the last auto increment value but there are other sections of my code in other applications that I plan on switching to MYSQL that depend on output parameters. I have't yet explored using stored procedures but at this time I would like to get this to work in a similar fashion to how I had it with MSSQL.

SQL Query Works In SQL Server But Not When Called From Checkbox

Nov 21, 2010

I've got a datagrid with checkboxes which calls a routine called checkbox_CheckedChanged. So far, so good. I've managed to get it to work out the value of another column in the dataview, which allows me to ascertain the id of the row I'm dealing with. I'm trying to get it to change the value of the column which defines the initial value of the checkboxes, but the SQL I've written doesn't work when called by vb.net - it does work when entered manually into SQL server, however. Here's my code behind:

.net - Cannot Connect To MySQL Server Over Different Domains?

Oct 4, 2011

I'm having a problem connecting to a MySQL server over two different trusted domains.We're developing an app for internal use and have been using MySQL till now. It's a desktop app written in vb.net.Up until now all the users were on the same domain and there were no issues. Just recently there was an higher-level decision to split users in 2 different domains for various reasons.The problem is that users from the new domain cannot access the server. If that helps, I was told by the administrators that the users from both domains are trusted. Both machines are running Windows Server - 2003 and 2008.The server port is open, the grants are all in there(base_class@%) but upon attempt access denied for user base_class@datablock2.

Connecting To Remote MySQL Server?

Jun 23, 2011

I have developed a frontend app using VB 2010 which is to connect to a remote MySQL server. My server has an internal IP address of 202.56.20.72 and an internal IP address of 192.168.20.44.

When I use the internal IP in my connection string and connect over LAN, the whole thing works fine. But when i changed the IP to the external address and tried to connect to the server over the internet, I get an error something like 'Failed to connect to MySQL server for user 'user'@'localhost', [using Password=NO]. This means that for some reason, it is not connecting to the server at all.
