Sql - Error Converting Data Type Nvarchar To Datetime

Sep 2, 2010

Using Vb.net/SQL Server 2000 updating a row via a gridview/sqldatasource

Stored proc:
@ISTag varchar(10),
@PCISTag varchar(10),

[Code]......

I don't understand where else it could be screwing up. I'd love to be able to keep it to a null value if it is one already, I'm just trying to get it to take anything right now and this is where I'm at.

Asp.net - Conversion Failed When Converting The Nvarchar Value '01:00' To Data Type Int

Oct 17, 2011

I 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, 2009

I'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,

travelQuery.CommandText = "SELECT [StartLoc], [EndLoc],[TravelTime], [AvgSpeed], [Distance] FROM [TravelTimes] WHERE [TripNum] = @trip"
travelQuery.Parameters.AddWithValue("@trip", travelParameter)

VS 2005 Converting Between Numeric Bases?

Apr 6, 2010

I'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):

'-----------------
Public Function FromBase10(ByVal iValue As ULong, ByVal cBase As ULong) As String

Converting Numeric Number To Roman Numeral?

Dec 7, 2009

Public 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, 2009

Description 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:

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

what i want to is convert this string to something like this

2.   JXK2LB AP2WXB S1P0XE ZXPA3H X1LAKW DOXPS3

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

I am trying to make a licensing system for my VB 2010 express application. (2) above will act as a serial key which can be derived from (1) which is an encrypted form of something unique of the client computer.

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

Get Nvarchar Data From SQL Server Database?

Jun 11, 2012

I'd like to get some values from nvarchar column (SQL Server database). My code looks like below:

Dim value1 As String
Dim con2 As New System.Data.SqlClient.SqlConnection
con2.ConnectionString = "data source=AAA;initial catalog=DWH;integrated security=SSPI;"
con2.Open()

[code]....

It works fine only when there are numeric values in the column. But in this column are stored variable characters values and this types of values are not being displayed on the page. I don't know what is the reason.I've tried to use getValue.ToString instead of getString but it doesn't work either.

Numeric And Non Numeric Data?

Jan 22, 2010

I am reading a data file and storing them in an array of string.Data is random, could be like "1","2","133,18" but sometimes there can be missing values like "?".Once I load the data in the array, I want to check if at least a majority (like 60% of them) are numeric values.If yes, then I wanna track down the higher and lowest value in the array, and output a range of 5.Loop through the array
   
If 60% of them are numbers (integers or decimals) then find highest value, find lowest value end if produce range

If for example lowest = 1 and highest = 100, range of 5 means 0,20,40,60,80,100 (so 5 ranges are 0-20, 20-40, 40-60, 60-80, 80-100).Also if the ranges turn to have decimals due to weird numbers, I would like to round them up.My problem is, in order to find highest and lowest when there are non numeric values in the array like "?", how should I handle those? I was thinking of something like Double.NaN but I would have to have an array of doubles.
