Creating An Update Query In VB?
Feb 15, 2012
I'm creating a form application using vb. I'm still new to this and I'm teaching myself via the internet so please don't be too mean. I wrote my code using queries that I created in visual studio. I don't quite remember how to create an update query and write the code to update different datagrids. I tried searching the forums, and I can't find anything that fits into the way I wrote my code. I have an update button that I want to use to save all the edited data in the form. Here's my code so far:
Public Class Form1
Private Sub Blsys_systemsBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Me.Validate()
Me.Blsys_systemsBindingSource.EndEdit()

I am able to add an existing MDF database to my project and apply it to a form with the appropriate binders and navigators and such and it works fine. I can hard code queries that are very successful. My question is this: Is there a way to add a textbox to the form, where I could enter a valid query that would execute on a button click event? It seems like I should be able to do so with SqlCommand, but I am just stumped.

I have been using adodb as my database connection to mysql from vb.net, now I want to know if i can create a query string with 2 separate query like so:
vb
dim querystring as string
querystring="update table1 set columname = 'value' where columnname='value';update table2 set columname1 = 'value1' where columnname2='value1'"
Then I can include that to my recorset:
vb
dim rs as adodb.recordset
rs = new adodb.recordset
rs.open(querystring,con, ADODB.CursorTypeEnum.adOpenDynamic, ADODB.LockTypeEnum.adLockOptimistic)

I need to run a query when I add/Change a value in my first column in a datagridview. When I add a value (a identifier from a table) in my first column, then I need the query to retrive the rest of the values in the table recordset. When I try to run a query, all i get is a query that updates my whole datagridview, and not only one row, with this code in the CellValueChanged module of the datagridview:
Me.myTableTableAdapter.FillBymyQuery(Me.myDatabaseDataSet.myTable, CType(DataGridView1.CurrentRow.Cells(0).Value, Integer))
Is there anyone who knows what I have to do, so I can add several rows to my datagridview, and let a query retrive my recordset based on my value in the first datagridview column?

I COMPLETELY understand how redundant this is but I NEED it.Upon users creating a User account which only contains the ID, Username, Password and CustomerID I must also have a record in Customers create itself but null everything and the User.User_Customer_ID must update to the newly created Customer.Customer_ID
I have everything working but this pesky update query. The ONLY thing it needs to do is change User.User_Customer_ID to Customer.Customer_ID I managed to story the User.User_ID in an integer called UserID and Customer.Customer_ID in an integer called CustomerID I have tried a million different ways with no success

ConStr = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
