Creating Extension Method For HTMLHelper ('TextBoxFor' Is Not A Member Of 'System.Web.Mvc.HtmlHelper(Of TModel)')?
Jun 13, 2011I have the following extension method that I've built and have working for one MVC3 project, but when trying to use it in another, the compiler (not the view) gives me the error;Error 1 'TextBoxFor' is not a member of 'System.Web.Mvc.HtmlHelper(Of TModel)'...Intellisense shows none of these html element shorcut methods.I'm sure it's just because I'm missing a reference or something, but beats me what it is.

Unable To Cast COM Object Of Type 'System.__ComObject' To Class Type 'System.Xml.XmlNode'
Jul 30, 2009Code: Dim dom As New DOMDocument30 dom.async = False
dom.Load(serverAddress & "/App/filelist.jsp?type=content")
For i = 0 To dom.childNodes.item(1).childNodes.length - 1 downloadfile(dom.childNodes.item(i), mcount, currentpath) Next
The above code is activated upon clicking of a button. i have the server address declared. and using the domdoc to load the jsp file to generate the xml data. and using for loop, i call the download file function which accepts the following parameters
Code:Public Sub downloadfile(ByVal domdoc As Xml.XmlNode, ByVal totalcount As Integer, ByVal currentpath As String)
The totalcount and currentpath work fine, but when i pass in the dom.childNodes.item(i) , error pops up.

.net - System.IO Will Copy Files But Fails To Update Destinations File Attributes?
May 25, 2010I have a little vb.net script that will copy a file, set its attributes to Normal, update the file time, and then set back the attributes to match those of the source file.
If IO.File.Exists(Destination) Then IO.File.SetAttributes(Destination, IO.FileAttributes.Normal)
IO.File.Copy(Source, Destination, True)
IO.File.SetAttributes(Destination, IO.FileAttributes.Normal)

I however I'm encountering a quite strange problem. On some configurations, IO.File.SetLastWriteTimeUtc triggers an UnauthorizedAccess error, although the IO.File.Copy instruction worked very well.

Asp.net - .Net Iniatialising A Class Using System.Reflection And System.Type To Create A Session Based Singlton Extension Method
Jun 11, 2009I have had several occasions recently to access a specific class several times over a relatively small time frame.So I've been storing the value of the class in Session and trying to access it on page load, if it's not available creating a new instance and storing that in session.
So instead of constantly replicating the same code for different classes on different pages I'm trying to create an extension method to do this for me.

I'm stuck on what to do when I make my new instance of my class (it would have to have a New() sub)
I'm not sure where to go from here... or even if this is the best way to do it.

I've been reading the MSDN Library and I need to use the StreamReader.Peek Method to check a text file while a I parse it.
When I try to use the Peek Method, I get an error saying , "Peek is not a member of System.IO.Stream."
I don't understand why it is happening because I am following the examples on MSDN, and I even checked other sources and it seems like I am doing everything correct. I am hoping it is just something small that I have missed.
I am also importing System, System.IO, and System.Text.
