View 4 RepliesAs I was starting on my lil project i realized that I would have a tonne of repetitive code. But wasn't sure how best to go around to just only have it in there once and just call on it. Not entirely sure how to do this as I havnt done it before, I was trying to mess around with it in a Function type thing but I had declaration issues which put me off course. Basically they'll be a few labels lbl8Beats(on click it loads the table in the datagrid (dgvCompositions)) is the first, and all the code from Dim conn As MySqlConnection to data = New DataTable, will be repeated.When i was messing around and thought I'd open the connection on form load, and I just had a bunch of declaration issues, and was unsure how best to go about this. Also since the Adapter = "would be changing on each label it just made me more confused.[code]

I created a mysql database and I want to connect to it through VB.Net 2008 using MySQL Connector Net. For this I made 3 forms, 1 form - login form, 2 - as ADMIN, 3 - from USER, the database each user has a role defined by regimes (admin / user). The problem is the following - after entering the username and password will not open one of the forms 2 or 3 but the application closes without any error.The code is:

View 4 RepliesI'm trying to make a rather simple Visual Basic app with which I can update some tables within my MySQL databases.I've been following this tutorial from page 3 on, as the first 2 pages where on how to initialize a local MySQL database.My MySQL database is on my website, so I thought I had to use the website's name instead of "localhost". Anyways, I now use this code:
Dim connection As MySqlConnection
connection = New MySqlConnection()
connection.ConnectionString = "Server=resload.com; Uid=***; Pwd=***; Database=***;"

I'm guessing the connection string is wrong, I'm going to try the server as localhost, but in the mean time hopefully someone might see what I might be doing wrong.I'd also like to look into doing it asynchronously, so the UI doesn't freeze,
I want to add a new Data Source (so I can use it with Crystal Reports) but using mysql, I did this before.
In the left side under: 'Data Sources' and then choosed 'Add New DataSource'Then I choose: Database > Dataset I clicked in 'New Connection' and I changed the first box (with 'change' button (as you can see in the image attached)) to what is showed in the image (MySQL Database..)The problem is, as I type the first letter of any of the textbox's that are below (server, user, or pwd) it closes that form showing the previous form (where I clicked 'New Connection')
Have someone had this problem ?I had a connection there, but since I changed the project from 'Framwork 4 Client Profile' to 'Framework 4' (so I could have the Crystal Report Viewer) the connection has gone and don't leaves me create it again.PD: I'm using dotNetConnector (already Added as a Reference)
