Ping The First Record In Database?

Mar 14, 2009

I currently have the below code to ping the first record in my database.

I'd like to set it up so that if an IP in the Database pings, it moves on to the next record e.g NetMonListDataSet1.Addresses.Rows(2).Item(0).ToString. if it doesn't receive a response it "sendsmymail()".

I know i need a For Each loop somewhere maybe? But i can't seem to fit it in.

Code:
Dim myProcess As New Process()
myProcess.StartInfo.UseShellExecute = False
myProcess.StartInfo.RedirectStandardOutput = True

Nov 15, 2009

I have a problem with my program, and it's really bad because I need to burn it to disk within 12 hours and I can't get it to work: If I create a record, add information to it and click on Next Record, the ID, Status and Notes boxes content will change but the rest of the controls contents are carried over to the next record and I don't know why or how. It was working perfectly but now it stopped and I never done anything.

Add A Record Into An Existing Database?

Oct 12, 2011

I'm creating another database searcher, only this one is a little better user friendly than the one I made with a datagridview. I'm using the "details" of my dataset(CustomersDataSet) and trying to add a record into an existing database. I'm using this code

Me.TableAdapterManager.UpdateAll(Me.DatabaseDataSet)

which worked for me when using the datagridview, but for some reason it won't work now. Even when I check for my test "add a customer" in the access database itself, it isn't added.
