Pass Content To Specific Record In XML Using LINQ?
Nov 14, 2009
I am using the following line of LINQ to drill down into an element. Is it possible to expands this code to drill further down so that I can add content to the <population> element in "Test2". I want to be able to do somthing like element.SetValue(1000000). However I need to expand the code below so that I can pass the entire query results into the variable called "element"'
Dim eles = From c In doc.Descendants("File") _
Where c.Attribute("Name").Value = "Test2" _
Select c

I've created a Setup project (in VB.Net 2008 Standard Edition) and I need to deploy some .rtf files in a specific folder for the user to edit. I've added these files to the project as content files but the Setup project installs them in Program File/MyApp along with the exe. As these rtf files need to be found easily by the user I need to specify a different folder on the hard drive. These are not mdb or xls files so are not used by the app itself. All the user needs to do is find them manually loading them into MS Word for editing. I don't need to load MS Word from the app, but I do need to deploy them so the user has access to them. How do I edit the file path so it does not bury them in Common Files or the User App Data or app folder itself? Ideally, since these are rtf files they could go in My Documents. (The app itself will work whether or not these files exist elsewhere.)
I'm working on a .NET application (VB 2008) that gets all of its data from a web-based Django application.I'm using Linq-to-XML and Linq-to-objects in the app.One API call is giving me XML data in the following format that I am loading into an XDocument.
The code below is used in a Linq to SQL solution, and is in the Load event of a form. It works fine to display an ordered list of people's names, and set the value member to that person's ID. However, I'm going to be using these 'people' comboboxes a lot, so I'd like to put a sub into my Utility code there is only one line in the form's Load event.
I want to call something like: Call ComboboBoxPeople(cbo, tblTurnbackMain, ReportedByID)
The sub would begin like: Public Sub ComboboxPeople(cbo as Combobox, tbl as 'sometype', fld as 'someothertype')
What can I use as the parameter types for tbl and fld?
