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.
... nothing is displayed. However, outside of the <% %> tags (ie in the HTML) £ displays correctly.
I have no trouble displaying the usual alphanumerics, it's just the £ sign that is proving problematic. The underlying file is in Windows 1252 encoding, and I need to serve it as such. If I save the file as UTF-8, I get mojibake instead of a £.
what I can do to make this work, or any settings that might be preventing it from working (other than saving the file in a different format)?
Is there a way to be able to create a new database when a company signs up to my site, and be able to use that database when he/she logs in, so for example if company A logs in he uses CompanyA database and if company B logs in he uses Company B database, now they all have the same table structure, just need to figure out a way to use a specific database depending on the user that logs in.
Im currently trying to send an email confirmation once a user signs up. Ive looked at links already on the asp.net forums and have had no luck getting it to function. My Sign up page reads data to a SQL Server correctly, what im trying to do is when they click BtnSignUp they will automatically be sent an email confirning that they registered. within my database I have a table "tblUser" and the field within it are "Email" "Password".
I am building a social networking site for employees and where an employee can sign up and create a profile and enter job employment history, interests etc. into text boxs and a aspx. page will be created showing all their details. Then in a data grid a preview of their profile would be shown allowing a user to click on that field which would direct them to that persons profile.
I am finding it hard to find information on how to automatically create a profile for each user that signs up.
I have a File Uploader in my ASP.NET application Using C#, we can upload any type like images, documents, pdf etc.
I m storing it in the Filesystem and having only the Name of the File in DB.My doubt is can we store the entire file, images in DB. State me Which is good practice and why we need to use it.
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...
I have an ASP.NET website in which the user has the Login/Logout functionality. There are some pages which are viewable only if the user is logged in. Now, after the user signs out, I noticed that the user is still able to see this restricted page on pressing the back button. I want to create the functionality such that once the user signs out, the page should not be viewable. How can that be done?
P.S I am not using built in Login controls in ASP.NET
I seem to be having some challenges with the data I am retriveing from a Webpage using the Webclient class. The code works fine, however I observe that the regular expression is not picking up the negative or positive sign in the Daily_Movement data. For example, a daily movement can be -0.31 or +0.31 but the code is not picking the sign in front of the decimal values.Here is my code
[Code]....
I think where the problem lies is the part of the code Regex r1 = new Regex("<span class="quoteData">.*</span>"); It picks up the values between the tag quite well, but not the signs in front of it. [Code]....
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'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 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 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)?
