Web Forms :: Dynamically Add Class To Div With FileInfo?
Sep 7, 2010
still really new to this, so I apologize if I explain my problem poorly. I'll do my best.I used this method to add an "active" class to my main navigation on another site. Now I'm using it to change the background image for a div based on the current page.Problem is, it's not working in this case. When I view the source I just see the tag sitting sitting there like it wasn't compiled:
[Code]....
And the rest:

I have a site that access its images in a subfolder under the site root. I am checking for the file existance using he FileExist method of the FileInfo class like this -
Dim fi As FileInfo = New FileInfo(MapPath(img.ImageUrl)) If fi.Exists Then
What I want to implement is saving the images under different domain in order to make images available to other copies of this site. Problem is when I try to FileInfo(http address) I am getting an error saying "URI formats are not supported."How can I get FileInfo to work with URI ? is there a workaround ?

I have a detailsview which uploads 4 files and uses the objectcontainerdatasource. However, what I would like to do is once I got my files from the fileupload object is to cast it to FileInfo type.At the moment I can get hold of the files via detailsview but this is where I need help; as I have four files to upload, I want to save them to either an array, collection or list of type FileUpload or FileInfo (preferably FileInfo) along with two other properties and then to pass these values to a method that saves these files to a temporary location. This brings me to my next problem. In the method that saves the files to a temporay location, whilst I can do this with FileUpload, I want to return from this method the new file path location as a FileInfo type in order to use this in another method.

I have a website built that uses master page templates. In the master page I have a simple menu in a list. This is not dynamic (yet!).
I am trying to put together some code behind to write a simple css class to one of the menu links if the Request.ServerVariables("URL") is equal to the current page URL
I have no code written because everything complains when I try to come up with something. I was thinking of doing it using a switch function but am I over complicating things?Below is the simple menu with the class I am trying to write to the link:
<div id="nav">
<ul>
<li><a class="selected" href="Default.aspx" title=""></li>
<li><a href="" title="ThisPage.aspx"></li> [code]....

I have a menu generated by my cms:
<ul>
<li><a href='default.aspx?pageid=2' id='link2'>rrr</a></li>
<div runat='server' id='menu2'>
<a href='default.aspx?subpageid=8'>rrr</a>
<a href='default.aspx?subpageid=9&siteid='>rrr</a>
<a href='default.aspx?subpageid=10&siteid='>rrr</a>
<a href='default.aspx?subpageid=11&siteid='>rrr</a>
</div>
<li><a href='default.aspx?pageid=3' id='link3'>Your Services</a></li>
<li><a href='default.aspx?pageid=4' id='link4'>rrrrrr</a></li>
<div runat='server' id='menu4'><a href='default.aspx?subpageid=1'>Single Equality Scheme</a>
<a href='default.aspx?subpageid=2&siteid='>Diversity Strands</a>
<a href='default.aspx?subpageid=3&siteid='>Equality Impact Assessments</a>

</div>
<li><a href='default.aspx?pageid=9' id='link9'>Contact Us</a></li>
</ul>
I would like to change the link that has been clicked, to class="active". I would like to add a class to the div if the page above is clicked too.
If (Len(Request.QueryString("pageid")) <> 0 and Request.QueryString("pageid") = 4) Then
menu & Request.QueryString("pageid") & .Attributes.Add("class", "active")
link & Request.QueryString("pageid") & .Attributes.Add("class", "activelink")
end if

i have a method that creates a thumbnail image from a fileinfo object thats an image.
so basically my method takes a FileInfo as a paramter, creates a nwe image, saves it and actually returns the FileInfo (no idea why - it doesn't really need to)
I want to delete the Fileinfo object (aka the file in the temp storage directory) after the image has been created but when i try to run fi.Delete() i get an error saying it can't because its being used by another process.
whats the solution to this? is it possible to delete this file in the same thread or am i going to have to create a service that runs on a schedule and cleans this folder.
What about creating a new fileinfo pointing to the current fileinfo and deleteing that?

I have a C# web page that allows the user to select an object from a DropDownList. Each object in the list has its own class. On the user making a selection information appears on the page that is generated from its respective class.
How do I instantiate a class depending on the users selection? I could use a switch statement that would instantiate anyone of the classes pending the dopdownlist.selecteItem value, however I was hoping to avoid that.

I have two folders in my asp.net web application in which I create new folders programmaticaly. The entire solution is under VSS source control. I was not able to manipulate these two folders programmably. For that, I gave {MACHINE}ASPNET user account full control over these two folders. Still, the "access denied to the path" error was coming. I saw that these entire folders were marked readonly. I tried to uncheck Readonly from explorer but not successfull, readonly check does not get removed. Also, if I copy files using method, the destinationn copied file becomes readonly. I have also tried File.SetAttributes (path,FileAttributes.Normal); but no success. How can I make the copied file not READONLY?

i set up Log4Net in a project, with the Log4Net.config file in "App_Data/config/Log4Net.config", and called the XmlConfigurator.Configure function with the following:
[Code]....
However, I the config file to be available in multiple projects, so moved it out to a solution folder (config/Log4Net.config).
Back in my MVC project, I added the config file as a linked file (and also set it to a "embedded" resource and "copy always" for the heck of it)
However I got no idea how the previous "var configfile = new FileInfo("????")" should read.
Tried it with and without Server.MapPath, using "Log4Net.config", "/Log4Net.config", "~/Log4Net.config", etc. No luck.
My guess it's because this Log4Net.config is not an actual file, but just linked.

<%@ Control Language="C#" AutoEventWireup="true" Inherits="Namespace.Path.To.ClassName" %>
<asp:TextBox runat="server" ID="txtComment" TextMode="MultiLine" ValidationGroup="comment" />

I'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.

I have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.
On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.
So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.
On my Page_Load, I'm running this after the buttons and labels are displayed:
For x = 0 to tblAccountList.Rows.Count - 1
'use a try to target the button, use catch to handle if it's instead a label, only one cell per row.
Try
Dim accountLink as Button = tblAccountList.Rows(x).Controls(0)
Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck
Catch ex as InvalidCastException
Continue For
End Try
Next
I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.

Using the following Webservice definition using aClientArgs as a complex type:
[System.Web.Script.Services.ScriptService]
public class Controller : System.Web.Services.WebService {
[WebMethod]
public void save_client(aClientArgs client)
{
// Save client data
}
}
Then defining aClientArgs as a sub-class:
public class aArgs
{
public string id = null;
public string name = null;
}
public class aClientArgs : aArgs
{
public string address = null;
public string website = null;
}
Returns the following WSDL fragment for the save_client args:
<save_client xmlns="http://tempuri.org/">
<client>
<address>string</address>
<website>string</website>
</client>
</save_client>
When I'm expecting the following:
<save_client xmlns="http://tempuri.org/">
<client>
<id>string</id>
<name>string</name>
<address>string</address>
<website>string</website>
</client>
</save_client>
So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?
