Asp.net - Conversion Failed When Converting The Nvarchar Value '01:00' To Data Type Int
Oct 17, 2011I don't know how to convert the nvarchar value into an int, but that is the way it needs to be set up. I've found other posts about this but I don't know how to use CAST in the INSERT statement I have. All the posts I could find were about converting to int in SELECT statements. I need this statement to change the field @Duration to an int in the database. @Duration is an amount of time. (01:00, 02:00...) They will all get rounded up to the next int value. So if a user enters 0:45, it should be converted to 1. how to get this INSERT to work?

Asp.net - Declaring A Nvarchar In VB/Matching An Nvarchar In A SQL Query?
Apr 22, 2009I'm working on an ASP.NET application that uses VB. I'm using a SQLReader/SQLCommand/SQLConnection within the VB file to try to pull data values.I was mystified to find out that the reason why the query wasn't returning any values, and someone here showed me how to troubleshoot the query to verify things were being returned, which they weren't.
I talked to a co-worker, and he asked if it would match because I was feeding a string, and the Text field for the database is an nvarchar. How can I declare the variable in VB so that when fed in as a parameter for the query, it can match?The types of data it looks to match are just basic things like "2", "2a", "1a", and so on.If there's no way to just declare the nvarchar, does anyone have a suggestion on how I might workaround that?
Side note: This is a continuation, of sorts, of this question: http://stackoverflow.com/questions/768052/sql-reader-saying-no-values-exist-query-seems-fine
Edit: I set things up like you guys said, but now I'm getting an error that "No mapping exists from object type System.Data.SqlClient.SqlParameter to a known managed provider native type. "I have the parameter as a form-wide variable like this:
Private travelParameter As New SqlParameter("@trip", SqlDbType.NVarChar)
And then inside the main form,

Asp.net - Must Declare Scalar Variable When It Is Already Defined And Sytax Error Near 'nvarchar' When Updating
May 16, 2012Solution at the bottom. I receive the following error when trying to update records: Must declare Scalar Variable @PaymentTermID Problem is, @PaymentTermID should be defined already in the Update parameters. The 2 functions for onrowdatabound and onrowupdate are tweaked versions of the ones found here for the DropDownList: GridViewRow.DataItem Property. Delete works fine. No new lines are added, just names changed around. I am not exactly used to working with asp objects.

VS 2005 Converting Between Numeric Bases?
Apr 6, 2010I'm having an issue with my base conversion program. It seems to have a problem converting from base36 to base10 properly. After debugging all night, I've found that it's one certain function that's not working properly. The function seems to convert every last test number correctly, until I start getting into 11-digit numbers in base36. I have the max digits allowable for base36 set to 12 (so as not to exceed the base10 18-quintillion or so that an unsigned long can hold). I'm starting to think the issue is with VB and not with my code.The function as I've written it is below (DIGITS is a global const string ="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ", and itr is a global integer used throughout the code for iteration):

Converting Numeric Number To Roman Numeral?
Dec 7, 2009Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
End Class
I haven't got the code, however I got the physical part of the program done with a label called Numeric Number and another called Roman Numeral, with text boxs next to each label. I also have a button called "convert" so when you enter a numeric number in, it'll convert it to a roman numeral. I need it to only convert from 1 to 10, but not accept a number less than 1 or more than 10.

Page Calculator - Converting Input To Numeric Variables
May 16, 2009Description of Program/Events. I would like to come up with a number generator that takes the Total number (for this example I'll say 20), divides it by 2, and does alternating additions so the end result will generate a list like this:
1, 11, 2, 12, 3, 13, 4, 14, 5, 15, 6, 16, 7, 17, 8, 18, 9, 19, 10, 20.
I can understand the arithmetic, just can't work out how to express this in code. The end result would be save in a .Txt file (I have added a SaveFileDialog1 control, but figure I need to get the result before I work on the export).

Converting Text Containing Alpha-numeric & Special Characters To String Of Only Capital Letters And Numbers

both 1 & 2 the above strings are fictitious (i made them up to make my point clear)

I will then confirm the (2) from the client.
