• SQL Server SQL Client Redirect - Database Mirroring

  Hi All, My apologies if this question seems abit basic, but I'm a DBA by trade and programming .Net isn't my strong point ;) I've enabled database mirroring on 3 SQL 2005 servers, a principal, a mirror and a witness. Principal - SQL 2005 Enterprise Edition, SP1 Mirror - SQL 2005 Enterprise Edition, SP1 Witness - SQL 2005 Express, SP1 I've written some test code to test the mirroring but as soon as the connection is pulled from the principal, the client re-direct doesn't work and the program bombs. I'd be grateful fi someone could have a look at my code below and tell me if there's any schoolboy errors (NB, the user running the code is a sys admin on all 3 servers) Thanks in advance.

• Visual Studio Express Editions how to convert Date to Integer

  I have 2 DateTimePickers and one is used for arrival date and other one is pick-up date. To find out delayed days I want to take away arrival date from pick-up date but the problem is it says you cannot convert date to integer. I would be appericiated if you can help me with this problem. DateTime.Subtract() subtracts two dates. So does Date.Subtract(). It produces a TimeSpan instance, use any of its properties to measure the difference. The Ticks property is the most accurate but you'll probably want to use something like TotalSeconds or TotalDays. The VB.NET DateDiff() function produces a Long value (not Integer). For example: Dim diff As Integer = CInt(DateDiff(DateInterval.Second, d1, d2)) ...Show All

• Windows Forms Listbox to show options from a related table

  On a Windows form, I have textboxes to show data rows of a main table. The main table has a foreign key to a minor table which is a list of status values ("Pending", "In Progress" and "Done"). The object is to display the status in a listbox or combobox. I want to know how to do this. Some notes: 1) The code to set up connections, DataAdapters, CommandBuilders, bindingsources, Datasets, etc works fine. 2) I would like to set up any constructs in code rather than with a wizard. 3) Unless I have to I want to avoid creating the relationship between the tables in the wizard. 4) I get the sense that one Dataset can access and update both tables, but I don't know how to tell the dataset about additional tables. ...Show All
