I have the following code.
Private Sub genWorkOrderCompForOneCustomer()
If customerNameComboBox.Text = "Please Select a Customer" Then
MessageBox.Show("Please select a customer to create a report for.", "Error",

When I run the the application I am not getting the current information from the sql database until I hit the refresh button and enter the parameter. I would like the information to be up to date when first loading the application.
I'm not sure if I should post this on this thread or in the Database section but I'm using VB2010 so I posted this unto this. I have a fresh installed VB2010 and a Microsoft SQL Server 2008 R2.And I can't seem to connect my database to VS2010. I've been searching the net but I can't seem to find the solution to my problem.
I have attached my SQL Server Configuration and the error message I got in VS2010.

View 3 RepliesI need to get the host out of the Request object. Which property should I use and why?
From MSDN:Uri.DnsSafeHost Property A String that contains the unescaped host part of the URI that is suitable for DNS resolution; or the original unescaped host string, if it is already suitable for resolution.
vs
Uri.Host Property A String that contains the host name. This is usually the DNS host name or IP address of the server.
My testing has been with the ASP.NET Development Server. Both of these always return localhost. Even when I put in 127.0.0.1, both return localhost.Reading on, the DnsSafeHost property will handle IPv6 addresses, as well as Unicode to ASCII conversion if needed. It can also account for IRI and IDN. Even though I currently don't care about these things, should I just use the DnsSafeHost property to be safe?
In my ignorance, I thought I could subscribe to any host, so I chose hostmonster, and copy files from Visual Web Developer to it, thereby creating my first website. Wrong! Hostmonster is linux-based, so the files won't copy without assigning an index page at the site. The rep at the host said that linux doesn't read the language(s) I've been using to develop pages, Visual Basic and C#.

I've never tried accessing a database on a remote computer, across the internet. A few questions though.
1) Do I just change the connection string address from a local path to a web address?

I'm trying to show a small DataGridView in my ContextMenuStrip that I have built. The DataGridView will show a unique list of values in a DataGridViewTextboxColumn "Sample ID" when its column header is right-clicked. I can get the unique values just fine, but I'm having trouble displaying the small DataGridView in the ContextMenuStrip. It currently looks like this.Notice, there is no data in the DataGridView. I have confirmed that the DataGridView.DataSource has several rows in it, yet the DataGridView shows nothing. Plus, I need to increase the size of my DataGridView, thus increasing the size of the ContextMenuStrip to show the DataGridView.
