VS 2008 - Adding Results From MySQL Query To Array?

Jul 12, 2010

I seem to be having a heck of a time trying to figure out how to add the results from a mySQL query to an array in vb.net. Right now, I only understand that you have to define the dimension of the array, however this is shy of impossible since the dimension of the array will change due to different results from the query. What is the proper way to take my results and put them in an array?

Delete A User In A Mysql Server Based On Search Results?

Sep 8, 2011

I have a datagrid control with a list of names that it retrieves from a MySql database. I can search through them until i have one result. I want to be able to Display a groupbox control when the number of results is equal to 1. Also, in the groupbox i have a button that when clicked will delete this user from the server and their information from the mysql table called "employee". when the user is deleted i'll display a confirmation message in a messagebox, and reload the table with the updated list. so far the only two problems i have are showing the groupbox when the results are equal to 1 and deleting the user from the sql server based on the name of the search result

Private Sub TextBox1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyUp
'Search Function.

Establish A Connection To MySQL Via VB & Display Simple Query Results On A Form?

Dec 12, 2010

I 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?

EDIT
Using MySQL 5.1

VS 2010 : Combine Similar Rows In A Datatable (the Rows Only Differ By One Column)?

May 8, 2012

I have three sub tables that I want to process. For each I want to combine the rows, as they are only different by contents in the second column(I want to do the same to the fourth column, later):

'Sub table 1
xx|C201 |02300877 |Samsung |....
xx|C201 |02300877 |Toshiba |....
xx|C213 |02300877 |Samsung

[code]....

p.s. For the fourth column, Manufacturer information , I want to do the same and I'd probably get something like this for the final table:

xx| C201,C213,C606,C619 |02300877 | Samsung
xx| C201,C213,C606,C619 |02300877 | Toshiba
xx| C303, C305,C712 |02301163
xx| C207, C209, C708 |02301165

MySQL Returning Only Column Name Not Value

Dec 30, 2011

myCommand.CommandText = "SELECT 'USED' FROM `KEYS` WHERE `KEYS`.`KEY` = '" + TextBox1.Text + "'"
Dim myReader As MySqlDataReader
myReader = myCommand.ExecuteReader
While (myReader.Read())
MessageBox.Show(myReader.GetString(0))
End While

The returning string is "USED". But that is wrong: it should be returning integer 0 instead. Why is that? I changed the MessageBox line to MessageBox.Show(myReader.GetInt16(0)) but now it sends me an error telling me that the input string is not in the right format..

How To Add Column With Auto-Incremental Name To MySQL Table

Sep 8, 2011

I'm using VB.net to write a MYSQL application and one feature I need to add is the ability to add a column for each week that my employees worked. For example I want the first column to be called "W1" and the next one to be "W2" and so on, right up to "W52". How would I add a column to my table and have it's name add 1 to its current value? If there wasn't any letters in the name it would be easy but I need it to have the "W" in the title as well to avoid confusion. to add the column I have this:

Alter Table Manager ADD W1 MediumINT;

I just need the part that adds an INTEGER to a VARCHAR datatype if possible... Maybe there should be some sort of data type conversion involved? Just to explain further, the black bar at the very top are the date stamps for each week, I would like to have this included in the datagridview if possible but it is not required. Under each week column the employees will be entering the percents they worked (example: 20%, or 0.20 is one day of work) I know this is an odd way of doing things but its mandatory... and i was wondering if it were possible to automate the creation of these columns rather than me having to manually enter them.

Querying A Single Column And Displaying All Results In A Single Textbox?

Sep 5, 2010

I am trying to make a list, separated by a comma, of entries from a single column in a SQL database. I have been spending the last several days searching for a way to do this, but every thing I found either didn't work, or wasn't exactly what I was looking for.

The query will pull all the email address that are not null. What I need to know is how to take the result of that query and make it look like this:

email0@address.com, email1@address.com, email2@address.com, etc, etc, ...

I feel like I should know this, but for the life of me, I can't remember nor can I find it in any of the textbooks I have.

I am using Visual Basic 2010 and SQL Server 2005. I also have access to Visual Basic 2005 if needed.

Show The Final Results Instead Of The Results Real-time

Sep 28, 2010

I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?
