DB/Reporting :: MySql Query Into A DataGridView?
Oct 9, 2009
So I'm working with a mysql database, and I already have some queries down. I have to make a windows application form in vb.net that can display the results of these queries in a dataGridView.Lets say I'm working with frm1, and i have datagrid1 which will be filled using the query "select * from xyz" when btn1 is clicked.Can someone please take me through the right steps to do that? References needed, connections to be made, etc. I did look through online materials, but they are mostly way too long and not dataGridView specific

I am using VB2008 Express and a MSSQL Server 2005 db by the way! I have a comprehensive SQL statement, which should fill my Grid:
DECLARE @Sum NUMERIC(9,2)
SELECT @Sum = SUM(I_LS.lmenge)
FROM dbo.lfs AS I_L
[CODE]...
Now here is my problem! I want to have a form with a datagridview that displays all of the values I am querying. This shouldn't be a problem I guess. However, I have no idea how I can integrate two textboxes that can be used to enter the selection criteria (WHERE I_L.lfsnr LIKE '%1253') AND (l.sped_journal = '11-08')[/SIZE]. I have googled and read many threads so far but didn't stumble upon anything that would suit my needs and answer my question. Maybe it's just too elementary!? By the way, it is very important that the input of textbox1 ((WHERE I_L.lfsnr LIKE '%1253')) is linked to 3 positions in my SQL query to define the search criteria!
The worst thing is that I don't want to have a bindingnav displayed! I do not need any delete, update or add functions just the select option, however!

I have a query from within my vb.net code which searchs for a record by date. The date being entered via the code is in format dd/mm/yyyy, i need to search in the database using yyyy/mm/dd? Ideally i thought there may just be a function within MySQL which will convert this. If not in vb.net to convert the string 01/01/2011 to 2011/01/01?

I can connect/login to my database, view a formatted table in the current window, however I want to click a button and see a new table set in a new window. Theoretically I should be still logged in/connection information saved but however I get 'unable to connect to database'.

I'm trying to do a looped insert using the MySQL Connector for .NET and for the most part it's working, except for it's missing out inserts. The code below is what i'm using. An example is there are 20 items in the listview and only 8 out of the list actually insert to the mysql database. It's as if the loop runs too quickly for MySQL to keep up. My issue is that eventually this loop will be inserting many thousands of entries and I can't have it missing information out.

I downloaded the free Visual Basic Express Edition to create an application that connects to a Mysql database. I searched for the connection string and found a bunch of different ones.I have no idea which one should I use with Visual Basic Express Edition. I have been using PHP, javascript and mysql for a couple of years, but I have never used Visual Basic and have everything to learn.

If I run a MySQL query at the same time I have a timer going, the timer lags, even though the query is on a seperate form. My computer has 8GB of RAM, so I doubt that that's the issue. Does VB stop the timer to run the query intentionally? Is there a way to prevent the timer from stopping/ lagging?

I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...
My Code
,
Dim dtParm As DataTable = MyDataSet.tblParameter
Dim dgv As DataGridView = Me.dgvResultNum_DataGrid
