View 3 Repliesfor starters not sure if this is the right place for the post considering that it includes MySQL and VB, its here.I'm trying to load data from one table into a combo box as the data you can select, this i have been able to do "tbl_Wind" using "WindDirID" and "WindDir"
also, I am trying to select (if it exists) a value from "tbl_date" "WindDirID" to select a value from the existing data in the combo box loaded from "tbl_wind"and finally, I want to be able to change the value in the "tbl_Date" depending on if a value is selected in the combo box.when a new record is created in tbl_date it uses default values, so there is always something in the field.below is about how far i got, and its the only part that works (extracted and edited of course to exclude the other queries)

I have recordsets in my MySQL database like this (in german): Karrieren im Porträt: Interview mit Thorsten Franck - „Ich liebe Produkte" Now when I get the data with the MySQL connector reader and write it into an xml file I get just this: Karrieren im Porträt: Interview mit Thorsten Franck Ich liebe Produkte As you (hopefully) can see, the minus (it's one of those long ones) and the upper and lower quote signs are not shown. The table is defined as UTF-8, the output of the xml file also.
View 1 RepliesI have a somewhat weird problem with a program i'am writing in VB2005. When I debug the program and start 1 backgroundworker (got 8 different backgroundworkers in the program) in VB2005 nothing goes wrong, but when i'm starting 2 or more backgroundworkers I get an NullReferenceException when trying to read from a MySQL database (withing a few minutes in debugging). This error isn't always in the same backgroundworker, but is always in the same block of code in a backgroundworker (1 of 8). I tried different approaches in getting the results I need, for example with read1.HasRows(), but this also didn't workt... the MySQL table doesn't also seem to be the problem.
Line 8 is where I get the error (read1.Read())... This is a snippet from backgroundworker1, but is also randomly happens in the other 8 backgroundworkers as well... When I'am trying to read te content of read1 is says "Nothing" when the error occures...

I'm trying to add values to a MySQL database. The values that I need to save come from several textboxes. The SQL-query is read from a XML-file.

I 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:

View 4 RepliesI have a VB.NET application and I need it to be able to display rows from a MySQL database. How would I do this?
Update: Another thing that I could do is have the app get a PHP page from the site that shows the DB, and gets the page every 10 seconds or so.
I'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.

Ok 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
