Connect Webapp VB/LINQ To A MySQL Database Server On A Linux?
Jul 7, 2009I have a programmer who is using VB and LINQ; and I have a MySQL database that is running on a linux server. My programmer tells me that:he cannot connect to the MySQL database via LINQ if he was able to connect then it would require all sorts of rewriting I don't know anything about LINQ but I thought it was an ORM. As such, any DB server that is supported should work just fine? Right? OK, so maybe it's not an ORM... maybe it should generically connect to ODBC and render similar results?

App That Uses Both An SQLite And MySql Database
May 29, 2012I am writing an app that uses both an SQLite and MySql database. The reason for this before you ask is that it means I can store a local copy of the data onto my user' own machines when they are offline, and then update them to a central server when they are next online.
The problem I have is that when using datasets (on tables created in identical fashion) the itemarray of the mysql database has 9 extra totally blank fields...where as the SQLite itemarray has only the values for the items.
here is a snippet of the code:
CODE:
ultimately I am getting an index size mismatch error but with both tables having the same number of fields this is confusing.

Connecting To Mysql Database From .NET?
Sep 19, 2011I'm having some trouble setting up a working connection to a mysql database from Visual Studio 2010.After downloading and installing the mysql-net connector, I set up a simple testing database in Xampp and experimented around a bit until I managed to read some values from the database and inserting new ones.I'm trying to access another database on a remote server and all I get is an error message: Unable to connect to any of the specified MySQL hosts.Basically, I'm only trying to execute this code:
Dim con As New MySqlConnection("Server=111.11.111.111;Uid=root;Pwd=mypwd;Database=mydb;")
con.Open()
con.Close()
(server ip looks a bit different of course)When I access my local database, it looks quite similar:
Dim con As New MySqlConnection("Server=127.0.0.1;Uid=root;Pwd=;Database=test;")
con.Open()
con.Close()
Nevertheless, I can access the remote database easily using a simple PHP script... no problems there.

View 1 RepliesNothing Happens When Update MySQL Database
Aug 27, 2011Ok so I have a Mysql dsetup called in-out and I have written a vb.net client program to get information from the table in the database, display it in a data grid view, and then allow to user to edit this information and update it on the server. Right now I am hosting the server on my Gateway laptop and also connecting to it from the same laptop therefore I'm using localhost as the server name. My problem is that when I go into the program and change the information and click update, nothing happens... the information stays the same yet there is no sign of an error, syntax failure, or program crash.
I've tried running this on another computer in my house and i get the same results. I can access the information without a hitch but updating it is where I run into trouble. If there was a problem with my code it would have displayed some sort of error or asked me to debug my script, which would have made it a lot easier to solve, therefore i am certain that it has something to do with my database. Before I got to this step, i kept getting an error when retrieving the information that said something like

View 2 RepliesApplication That Has To Connect To A MySQL Database And FTP
May 5, 2012I'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.
