C# - Converting Characters In A XmlText Node?

May 23, 2012

I'm having problems while attaching some strings to some XML nodes.To explain this better I've made a simple example... just imagine that I have this XML code:

<song>
<title>
Surfin&#39; USA
</title>
</song>

notice that instead of simply writing "Surfin' USA" I'm expressly using &#39; instead of the single quote character.The XML code is valid - or at least it has been considered valid by some tools I have found and tested online.My Problem is that when I try to put that string into a XmlText object, this way:Dim xmlDoc As New XmlDocument()

LINQ To XML When A Node Does Not Exist

Jun 28, 2009

I was writing a generic class to read RSS feed from various source and to consolidate in one collection of object in VB.net.

Basically the function - using LINQ to XML - is working properly, but I have a problem when the RSS feed I am trying to read does not contain one of the node (as you know, many of them are optional). I would the returned value to be an empty string or nothing, but instead I get a runtime error back. I searched the web for the same problem and I found this post [URL] that apparently explain a workaround, but it does not work with my code.

I am also surprised by the little resources I am finding about this issue, so I am now wondering if I am even putting the question in the right terms...

Following you can find the code:

Dim PostsEnum = From BlogPost In XMLSource.Descendants("item")
Order By DateTime.Parse(BlogPost.Element("pubDate").Value) Descending

VS 2010 LINQ XML - Write To Node?

Jul 2, 2010

After being quite sick of the my.settings-file behavior, I started to create an XML-file (with unique values). Now this works great!!! All my settings, connectionstrings, etc are loaded from an external file and won't be overwritten by the app. itself. But I was wondering how do I save a value/setting? Simple example:

HTML
<test>
<country>Holland</country>

[code]....

read the XML and node:

vb.net
Dim readXML = Xelement.Load(Application.StartupPath & "XMLFile1.xml") ' check if the node isn't empty (crash) If readXML.Descendants("country2).Nodes.Count > 0 Then Textbox1.Text = readXML.Descendants("country2).Nodes(0).Tostring() Else

.net - Write A Linq To Sql Query To Find Records Where Field Name Can Match One Of Dynamic Number Of Strings?

Mar 21, 2012

I have users check off lab facilities in a UI. I want to use linq to fetch corresponding records for all of the labs that they have checked off. Basically,

Dim myRecs = (From l As EpiData In myDataContext.EPIDatas Where l.facility= _
one of the checked labs

So basically, I need to write a linq query where the "strings" to match are determined at runtime. Is there any way to do this easily? I know that there is a library out there called dynamic LINQ, but (1) it's in C# and I'm writing in VB (2) I'm really just looking for a single, simple solution for this single case.

.net - Building A LINQ Expression To Find Items Related To All Descendants Of A Tree Node?

Mar 7, 2011

I have built a database structure that represents a category tree to help classify some of the data we have stored. The implementation is that each record in the Category table has a nullable foreign key back into the Category table to represent the parent Category of this category (one-to-many), essentially allowing for subcategories within a broader parent level. There is a CategoryMembership table that links a record in the Item table to its respective Category (many-to-many). I have created the DBML for this database, and it has a member access structure that includes the following:

Forms :: "Locking" Characters When The User Edits A Treeview Node's Text

Jun 9, 2010

I have an application where I'm allowing the user to edit the text of a treeview node. Is it possible to "lock" portions of the node's text to keep it from being edited?

For instance, if the text is "BK01" originally, can I keep the user from editing the "BK" prefix?

I currently validate the user's input when they are finished editing, but I'd like to keep them from entering incorrect information to begin with.

Regex - .NET: Manipulating TextBox Input: Dash Every 5 Characters And Removing Special Characters?

Dec 21, 2011

Essentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.

This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.
