I'd like to be able to achieve this same functionality except to fire when the desired index IS NOT set. I cannot simply create a bunch of Conditions for each index other than the one I specify due to the way this is dynamically being done in my application.
I try to compare Datetime.Now with a Datetime variable I set, using the Datetime.CompareTo() method. I use a timer to compare these every second and display the result, but as the current time approaches the time I set, the result changes from 1 to -1, but never 0, which means these two are never equal. I'm suspecting the Datetime structure contains milliseconds?
I have a simple method which takes an Object and return string "No" or "Yes". Basically I want to display "Yes" or "No" when a bool value of 0 or 1 is there
But everytime there is a 1 passed to the CheckValue which in the debug shows as true, It never evaluates being equal to "true" what am I doing wrong? My Checkvalue is always returning "No" no matter what I pass.
I am trying to split a collection into multiple collections while maintaining a sort I have on the collection. I have tried using the following extension method, but it breaks them incorrectly. Basically, if I was to look at the items in the collection, the order should be the same when compared to the broken up collections joined. Here is the code I am using that doesn't work:
public static IEnumerable<IEnumerable<T>> Split<T>(this IEnumerable<T> list, int parts) { int i = 0; var splits = from name in list group name by i++ % parts into part select part.AsEnumerable(); return splits; } int parts = number of sub enumerables
I keep getting an error:Index (zero based) must be greater than or equal to zero and less than the size of the argument list.y code:
OdbcCommand cmd = new OdbcCommand("SELECT FirstName, SecondName, Aboutme FROM User WHERE UserID=1", cn); OdbcDataReader reader = cmd.ExecuteReader(); while (reader.Read())
I'm facing a problem that Google couldn't solve yet!I'm trying to store URLs in an XML file. Problem is that these URLs contain Equal Signs (=) in them. And that generates an error.Here is my code: (**token is a variable that contains the URL)
Dim child As String = vbCrLf & "<Link URL='" & token & "'></Link>" Dim fragment As XmlDocumentFragment = doc.CreateDocumentFragment fragment.InnerXml = child
The error message: (Error line and position are meaningless here) '=' is an unexpected token. The expected token is ';'. Line 2, position 133.I've replaced all '&' symbols with '&' in case they were the ones causing the error, but no luck so far.
I have a basic web form with about 5 textboxes. One Textbox is "Date1" and the other is "Date2." Is there a way to set the value of Date1 = Date2 after the user enters a value into the Date1 textbox? I'm using Visual Studion and C#. I'm not much of a programmer, so the less technical the better.
I'm trying to pass post data from one page to the next but PreviousPage always equals null.This is what I have in the original page (inside an updatepanel
I have ASP .NET page, and VB module. I have DropDownlist in the ASP page that retrieve information from SQL database. I am trying to make a string varaible equal the value of the dropdownlist selected.
If I want to validate that a text box contains an integer greater than or equal to zero. Do I need to use TWO asp:CompareValidator controls: one with a DataTypeCheck operator and one with a GreaterThanEqual operator?
Or is the datatype operator redundant? Can I just use a single validator with the GreaterThanEqual operator (and the type set to Integer)?

So admitingly I am fairly new at .NET...I have been a PHP guy for rather long time...
Heres my code:

Essentially what I am trying to do is query the SQL database by the username. This above code is a method within the user respository for fetching a user by their username. The variable "username" is passed in as a string.
When the method is called a recieve the following error:
The data types text and varchar are incompatible in the equal to operator.
This to me is rather confusing since the field in the database, user_username, is a text and the variable passed in, as said, is a string. They should be synonomous for all practical purposes.
I want to retrieve all the records where the datetime is greater than or equal to 30 days ago. What is the correct formatting for this line: WHERE Property.dateadded >= NOW -30 days .. Dateadded field is in datetime format.
SELECT TOP (1) Property.Name, Property.Price, Department.DepartmentTitle, Images.ImageId, Property.DateAdded FROM Property LEFT OUTER JOIN Department ON Property.DepartmentId = Department.DepartmentId LEFT OUTER JOIN Images ON Property.PropertyId = Images.PropertyId WHERE Property.dateadded >= NOW -30 days
I've found a lot of similar topics but none of them solves my problem.
I have table structure like that
[Code]....
Everyone suggests to change ntext type to nvarchar(MAX) and life will be beautyfull. But... First, I need ntext, simply because there should be text in this field.
nvarchar(MAX) equals 4096 bytes which is to small for large text. Second, I already have table with ntext field, which does not cause this error.
The demo web project that ships with the VS2010 contains a system.web.ui.webcontrols.menu control.
That particular menu includes the IncludeStyleBlock property.
When the IncludeStyleBlock property is set to False the menu is displayed as it supposed to. The menu gets destroyed if i set that property to True. So here is my main question...
Is there any way of preserving the appearence of the menu, with the IncludeStyleBlock property set to false?
P.S. I have to set it to False... since my provider does not support the forth generation of the .NET framework.
I get the following error during DataBind to a grid: [System.FormatException] = {"Index (zero based) must be greater than or equal to zero and less than the size of the argument list."} What does this mean? Is {1} not a string or is it because of something else?
