• .NET Development SqlDateTime Overflow Error

  I'm getting SqlDateTime Overflow Error when I try to INSERT a DateTimepicker.Value.ToShortTimeString (e.g. "10:57 PM") into my Sql 2005 database column (type nvarchar50). It used to be a Date/Time type column but I changed it. I changed it in the db, I changed it in the dataset designer but still the same error. How can I make Visual studio forget it was a Date/Time column and allow me to store 10:57 PM as a string Where else do I need to change/remove the Date/Time setting Thanks for any help. Somewhere there is still a reference to a datetime, otherwise it wouldn't be giving you that error. A ...Show All

• SQL Server Passing a report parameter to Reporting Services from VB

  I have a Report that I want to access that has a parameter input for the date, Production_Date. I want to allow the user to use the DateTimePicker to select the date to use for Production_Date. I can't seem to find the correct way to format what I'm tring to do. My production date field is in a format without punctuation so that it becomes: Dim ProductionDate = ((DateTimePicker1.Value.Month * 1000000) + (DateTimePicker1.Value.Day * 10000) + DateTimePicker1.Value.Year) which gives me a value that I want to send as a parameter for the Reporting Services report that I have located on a tab in my project.

• Visual Studio Express Editions Parenting a form?

  Hi all ~ am trying to dynamically create a form and display it "inside" a panel on my main form. Am coming from Delphi where similar code would work - what do I need to do in C# TIA, Kai private void button1_Click(object sender, EventArgs e) { Form f = new Form(); f.Parent = panel2; f.ShowDialog(this); } I'm not sure that you can house a form inside a form. The way to do this would be to create a user control that is used both by the form, and can be shown inside your form. To add a control dynamically, it needs to be added to the parent forms controls collection ( t ...Show All

  I have a need to export all of the stored procedures in a database to files on the server dirve. I know that this can be done through the management interface but I need a way to do it programatically.
