Establish A Connection To MySQL Via VB & Display Simple Query Results On A Form?
Dec 12, 2010I have a project in Visual Studio 2008 and there is a working data connection to a MySQL database. In other words, I can query the db directly from Visual Studio and it will display the results.
I've tried a couple of approaches that I found online for writing a connection string and accessing the db, but no luck yet.
All I'm trying to do is code a button to query the db and then reset the text property of a label/textbox to display the results based upon another label/textbox value.
The pseudo-code I am imagining is something like this:
Private Sub query_submit_button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles query_submit_button.Click
result_textbox.Text = SELECT field FROM table WHERE otherfield = key_textbox.Text
End Sub
I didn't see any related questions posted on SO - forgive me if I missed one that already exists and this is a dupe.
What is the correct way to accomplish this?

Take XML Data And Create A Line Chart With It?
May 18, 2009I have a program written in VB6/VB.net and its supposed to calculate a set of numbers based on user input. From there the data is saved into an xml file. I want to be able to take the data from the xml file and draw a chart representing all the data. I found a tutorial that draws line graphs based on an predetermined array of data, but I need the program to take the data from an xml file.
Heres the code for the line drawing program:

View 2 RepliesConsolidate String Data From Query Results?
Nov 12, 2009I am running the following query against a database of research reference works (books, articles, etc.):
SELECT [Names].[Last] AS Authors, [References].PubYear AS [Year], [References].ShortTitle AS Title, [References].SourceWork,
RefTypes.Description
FROM ((([References] INNER JOIN
Contributors ON [References].ID = Contributors.RefID) INNER JOIN
[code]....
This query returns one row for each Author (contributor type=1), of the specified reference. The rows will all be exactly the same except for the Author last names taken from the NAMES table. For example:
Author Year Title SourceWork Type
--------------- ------- --------------------------------- ----------- ----------
Rahner 1966 Revelation and Tradition Null Book
Ratzinger 1966 Revelation and Tradition Null Book
I'm looking for a way to consolidate the string data from the Author column into one string, so that this can return a single row with the Author field looking something like "Rahner, Ratzinger" -- like one could do if it were numeric data by using the GROUP BY clause with an aggregate function such as SUM or AVG.

View 4 RepliesDisplay Results In A Chart Control?
Jun 6, 2011I'm trying to present results on an aspx web page where a store procedure parameter is defined by a dropdown list control on the page. I have followed this guide from Microsoft and have my resultset presented in a DataGrid view. But I cannot seem to adapt it to present the resultset in a chart.
As you can see from my VB code below, I thought it would simply be a case of adapting the GridView databind to a Chart. I have tried various other options, and have successfully generated my data in a chart using a hard-coded parameter in an SQL statement on the ASP page. But when it comes to using the control, I get an empty chart.
Below is what I have so far.
