I am building an app where I need to allow a user to add a large text (a story) to his account in server.This will be done like this:
application developed in vb.net for article formatting pass the story to php page using request variables (because direct connection to MySql server can reveal my password in app exe) php file will store data to database.But right now I get: 414 error - url too big.
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.
Query: INSERT INTO myTableName(ID, Groep, Naam, Achternaam, Intern, etc...) VALUES(NULL, NULL, tel_txt_group.Text, tel_txt_name.Text, tel_txt_surname.Text, tel_txt_intern.Text, etc...)
Unknown column 'tel_txt_group.Text.ToString' in 'field list'
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:
CODE:
ultimately I am getting an index size mismatch error but with both tables having the same number of fields this is confusing.

I think I already know the answer to this, but just to be sure, is there any way to connect to a MySQL database in VB?
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.

I have memebrship system with mysql database.In the table I have comumns named Username, password, information...I have to found the row with the username who have logged in and put the text from information column in textbox...
View 1 RepliesOk 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

im 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.
