I have five buttons. Each one has the logo of a website. When the user clicks the button he should go to the website.The five websites are stored in a database (because they need to be changed later during runtime, and the changes saved for the next time the program is opened), in the adress colum.The number of the button corrosponds to the row number of the adress.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
WebBrowser1.Navigate(Me.Table1DataGridView.adress(1))

I have a report made in Crystal Reports XI. The report is generated and exported to PDF in visual basic script using COM interface. Generally everything is running smoothly, but in one case generation breaks with error: Failed to retrieve data from the database. Details: [Database Vendor Code 9421]
Database used is MSSQL 2005 connected over ODBC to CR XI. When I am opening report with exactly the same parameters in Designer, everything works fine.It looks like it is data related, but it is hard to trace since the whole report is pretty sophisticated. Anyway I spent half a day on crawling over Dr. Google and it seems that he has no clue what might be an issue.

I am using microsoft access 2003 and visualbasic.net. I am trying desperately to add a database using the wizard, and it lets me go through with it, testing the connection is good, but when I try to finish it gives me an error: "<customers>Could not retrieve schema information for table or view customers." What am I doing wrong? I've added databases in the past without this problem using the same Access.
Im' trying to retreive a recordset from a database on MSSQLSERVER 2008.For some reason it doesn't work at all.I try the ado commands (all the ones i've found so far) but i always get stuck somewhere.how to connect to my database and retreive data it would be really wonderfull.The data source binding stuff, all works but no success however with connecting a recordset.
we want to retrieve all data in our database but we dont know how to do it.. hmm.. we just use to retrieve data one by one.. its just by the search button.
I am using MVC3 and EF 4.1 (Oracle DB). Let's suppose I have:
Public Class Parent Public Property Id As Integer Public Property Name As String
[code]....
I want to retrieve all parents from the database and for each parent I can access its children.I want to do the following:
Dim firstParent = (From q In db.Parents Select q).First() For Each child In firstParent.Children 'Do something Next
The problem is that I would like to enumerate the children from the youngest to the oldest. Is it possible without the client-side sorting? If yes then how can I achieve that? I know how I could achieve what I want with an SQL query, but I cannot make it work with LINQ...
EDIT:Since this seems not to have a solution in my case and sorting everytime I request data is not an option, maybe there is something I can do when I insert the data to the database? I do not have a control on which order EF saves items to the database when I call db.Save(), but maybe there is some syntax I could use to require ordering based on some property.
I still cant think a way to get my database from the datagrid in form2 and display it on form3..my little program is like a schedule that you'll edit your students class hour,subject and teacher.. then after that when you view your schedule.. you'll see only what subject you'll be at in that student data schedule...i've tried dbgrid.columns(n).text = label1.caption, but i found out that it'll copy the data but only those on the 1st row >.<. ill upload my program here for you guys to have a hint what program exactly im making on.

I have a database I have linked in via the VB2008 DataSources panel on the UI, and using the DataSet name created when that was done.
