The biggest difference between double and decimal is that double is a floating point variable type whereas decimal is a fixed point variable .What it means?? Please Explain the abovePoint with Example.According to me both are used to store the folating numbers,then whats the difference between two?

Both of these used same function. So why these two have been provided?
Secondly Why there is Not a constructor like:
String abc=new String("Hello");
i have a double, the decimal place isn't fix (8-?) i want to fix the decimal place to six (for example: 1,234567). this is my double:
CStr(score)
i have a strange error creaping into my web app but am unsure as to how to fix it. When i run this code on my debug workstation it works fine but when i transfer it to my server things seam to go wrong.
dev station (windows 7) + VS2010
regional and language settings all set to uk
server (windows 2008r2)

What seams to be happening is that when converting a string to a double it works correctly on the dev environment but moves the decimal place to the end on the server.
example code(vb)
dim lat as string = "52.983829"
dim long as string = "-0.036500"
dim latint as double = lat
dim longint as double = long
now on the dev server the value of latint is 52.983829 as you might expect but on when published to the server it becomes 52983829.0 the same with longint on the dev staion it is -0.036500 but on the server it becomes -36500.0 i get equally confusing problems if i try to change it to an integer instead.
Using ASP .Net 4.0,Entity Framework and EntityDataSource.
I have some currency fields that are defined as Decimal. I would like to allow the user to enter a (leading) dollar sign in these (TextBox form fields). Although, when the EntityDataSource goes to save the changes to the datbase, it throws:
Error while setting property 'QuotedMaterial': 'Cannot convert the value of parameter 'QuotedMaterial' to the type 'System.Decimal'.'.
Does anyone know how I can "tell" the EF to allow dollar signs and convert (drop) them accordingly? I am trying to avoid creating my own Data or Business Logic layer for this particular application. I would like to stick with the EntityDataSource and other
"built in" controls to minimize the C# code behind as much as possible.
I guess my only alternative is to deny $ (Dollar Signs) (and commas too for that mater, it doesn't like them either). The problem is I am porting a legacy application and I would like to keep it as close to the original as possible (and they are currently
allowed to enter dollar signs in this application). You see, they use copy/paste for data entry quote often on this particular form and it just so happens that the source data (they are copy/pasting from) always has a $ in it...
Is there a way to get the difference between two dates in Month. I would like decimal for the day.
EX :
First Date : 2010-12-20
Second Date : 2011-12-30
This is like 1 months and 10 days between these date.
The difference should give me : 1.33
DateTime dt = new DateTime();
dt = Convert.ToDateTime("2011-12-30"); ;
DateTime dt2 = new DateTime();
dt2 = Convert.ToDateTime("2010-12-20");
int monthDiff = System.Data.Linq.SqlClient.SqlMethods.DateDiffMonth(dt,dt2);
In VB how do you return the difference between two dates expressed in years as a decimal.
(DateDiff(DateInterval.Year, DateOne, DateTwo))
So that the result returns a decimal for example 15.76 years and not an integer

I am using SQL2008 and created a full-text index on 1 of my tables. Going through the wizard, I was offered (2) types of population schedules as follows:New Table Schedule: Define a population schedule for a table.New Catalog Schedule: Define a population schedule for a full-text catalog.I am familiar with a 'Catalog' schedule for population which I do nightly and was similar to configuration on SQL2000 for a full text index. However, what is the difference for a 'Table' schedule vs the 'Catalog' population schedule? I have the definitions above, but if someone with knowledge could offer a better in depth explanation in comparison, and if I should use both or not (I have just a Catalog population scheduled currently),

I was read your post: "Export GridView to Excel in ASP.Net with Formatting using C#" and is very useful. That code works perfect. But I need create a new format for a specific column in my sheet before to export it. For example:My DataTable have a column with decimal numbers and I'm trying reduce the tenths for each number.I want this: 2,874444 ----> 2,87 for a specific range. In this case I need it for all numbers in the column 13 or well said for the Column called N in Excel. Only reduce two tenths.
I used:
xlWorkSheet.Range["N"+h,"N"+h].NumberFormat = "0.00";
And no works (h is for rows, N is the column. Into a foreach).
is there any difference between sql express and sql client. Actually I have been told to install a sql client using which i will connect to the sql server installed remotely.

View 2 RepliesI am using visual web developer express edition and Im a new user of this tool. Im just trying to close a browser when the user clicks a button. The code below has two discrepancies. First, if you are using IE it works fine,however if you will be using other browsers like google chrome or firefox it will just close the browser if the button is the first control to click in the first time but if you have already click or use other controls on your page or has already browse another page it will not close anymore. Why is that? I need a code that is capable of closing any type of browsers anytime a button is click.
Here's my code:
<script language="javascript" type ="text/javascript" >
function CloseBrowser()
{
window .close ();
}

my ASP.NET web application uses windows authentication on our intranet. I want it to be able to make a server-side http request to another server on the same domain that also requires windows authentication. I've followed the instructions on temporarily impersonating the authenticated user when making the additional request here: [URL] Using code like this:
using System.Security.Principal;
// Obtain the authenticated user's Identity
WindowsIdentity winId = (WindowsIdentity)HttpContext.Current.User.Identity;
WindowsImpersonationContext ctx = null;
try
{
// Start impersonating
ctx = winId.Impersonate();
// Now impersonating
// Access resources using the identity of the authenticated user
var request = WebRequest.Create("http://intranet/secureapp");
request.Credentials = CredentialCache.DefaultCredentials;
var response = request.GetResponse();
using (var streamReader = new StreamReader(response.GetResponseStream()))
{
Response.Write(streamReader.ReadToEnd());
}
}
// Prevent exceptions from propagating
catch
{
}
finally
{
// Revert impersonation
if (ctx != null)
ctx.Undo();
}
// Back to running under the default ASP.NET process identity
But, unfortunately, I always get a 401 unauthorized error. Do I need to configure our webserver with active directory to allow it to delegate the autenticated user (could be any one of about 200 users, so don't want to have to do anything 200 times :))? If so, can anyone tell me how to do this?

It's trying to update a column which data type is set to decimal. Just so you know what I really need out of it, here is an example:
[Code]....
The answer of which should add on 0.5 to the original value. If I were to use the increase value of 60 which then becomes 60/60 it will work.I'm dividing by 60 because the increase value is per hour so I make it smaller to get per minute value. Why is it doing this?
Some values are returning 2.0 but I need it to be 2.00 as this is a money value that is displayed to the web page.
I am doing:
Math.Round(value, 2);
Is there a way to force it to 2 numbers after the decimal?
I need a validation regex for decimal. It should allow upto 5 digits after decimal.
Allow:
1
1.0
12.0
12.01
123.01

1,123.013
21,123.01234
3,21,123.01234
How Can I do regex for this?
I have an application that allows admins to add types such as document types and training types that are in seperate tables with a foreign key in a transaction table.
When structuring my class I decided to go with an abstract-like pattern (without the factory methods though). So I have a Type abstract class that defines my Save, Delete, and GetList methods. I have a training type class that inherits this class. The thing is all types have 3 main properties - defined in the abstract base - but have different source tables and thus different store procedures in my DbCommand object. So basically I repeat setting up the same parameters on all the derived classes. I would like to implement the common stuff in the base but I am getting thrown off by the difference in data sources.
I want to know where lies the difference between these two.I had a google search on this topic and a lots of replies and each of them tell the same thing:
Eval means one way binding(i.e;readonly)
Bind means two way binding(i.e;both read as well as write the datasource)
but none of them explained it more clearly.all i want to know is how can i use the Bind to update/insert something from the datasource?
