I am looking to write a stream filer in a http module that anyalyze the output html of a page, search through the pages html for any images within the page, check if the source of the image has a full path or relative path. If its a relative path, alter it to have a full path. Anyone ever write anything anything like this? Looking for some examples of such?

I have a few css files, javascript files and images referenced in my master page. When I do a "View Source" of the pages that use this master page, I can see that the css files are showing correct paths but javascripts and images don't. I tried using "~" in path but nothing worked so I used relative paths.
If I have a path for css file as "../../css/blah.css" and a page that is in sub-folder uses this master page, it correctly shows the path as "../../../css/blah.css". But the images and javascript paths continue to show the original path (hence broken images, javascript errors, ...).
A javascript source listed as src="../../scripts/blah.js" continues to show as "../../scripts/blah.js" instead of "../../../scripts/blah.js". Same thing with images. I did try "~/scripts/blah.js" and "~/images/blah.gif" but still can't find it.
I have an excel file in my Response Output stream. I can Open the stream as a file after a prompt, but it doesn't seem I can save it directly to a specified folder on my client.

I need good css for Gridview just like the mac css
can we provide the filter functionality to gridview like the excel filter.
In securing actions/controllers, do I have to create a custom filter or use MVC built-in filter?
To use the built-in attribute Authorize() on an action/controller or create a separate class that inherits the ActionFilterAttribute which has a method (OnActionExecuting) to override and do the authentication there?
In my organization we use nested groups. For a particular usage, we have a group (let's assume that the group name "kuku"), and the names of all the nested groups under it contains "kuku" as well.
We may assume that no other group in the LDAP has "kuku" in the name.
I need to create a filter which will return all the users which belong to one of the "kuku"s group.
Obviously, using this filter will bring only the head kukus
(&(&(objectclass=user)(objectclass=person))(memberOf=CN=kuku,cn=...rest of the group DN...))
How can I use wild card to fetch all users which belong to any kuku?
For example: (&(&(objectclass=user)(objectclass=person))(memberOf=CN=.*kuku.*))
I have decorated my base controller with a couple of action filters. They work fine.
One of those filters sets up the request - does things like set the culture based on the domain, etc.
I also have a handful of actions that require authorization using the Authorize attribute.
My problem is that when an user attempts to request a page they are not authorized to access, the authorization filter kicks in and redirects them to a page telling them that they cannot vie the page.
The issue is that the action filters never run so the culture and other request data is never set. This effectively causes language to be wrong in the view and other data to be missing.
I know that authorization filters run first but my question is this: How can I design this such that I can ensure that certain methods are always run before the view is returned, regardless of the authorization.
does a action filter override a controller filter?

Is there an alter statement to rename a column name? Maybe dropping and adding a new column is the only possible way -- or so I thought?

I have an SQL table called tbl, im trying to add the columns A, B and C to it.
When i execute the command :
addcolumns = "ALTER TABLE SqlCreatedTbl ADD A char(50) ;";
cmd = new SqlCommand(addcolumns, conn);
conn.Open(); cmd.ExecuteNonQuery();
The column is added perfectly and i can see it in the table !
However, when i try to add multiple columns, it does NOT work, it gives me an error..
the command im writting for adding multiple columns is the following:
addcolumns = "ALTER TABLE SqlCreatedTbl ADD ( A char(50), B char(50), C char(50) );";
the debugger highlights the line : cmd.ExecuteNonQuery(); and throws the following exception: Exception Details: System.Data.SqlClient.SqlException: Incorrect syntax near '('.
I am developing a website where the user enters data into a form. The user can then go back and edit the data that is saved in a session variable and then the data is resaved in that session variable in an arraylist. However, for some reason although the data is resaving it is resaving the original data. I know this as I tested the code without the remove request to the arraylist and the original data was just added to the bottom of the array. I wondering if anyone would know why the new data is not saving. Any help would be really appreciated as I have only been programming for a few of months. Some of the code is below.//The gridview shown on a page which lists the objects saved by the user which he/she can edit and edit is the only one I am concerned with here as the other works
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false"
OnRowCommand="EditPenaltyPointsGridview" >

I have the following code that I wasnt to alter the Dataset before it is bound to the dropdown list.
[Code]....
What I would like to do is ALTER the dataset for the Parent (dropdown list - ddlRT). I need to format and disable certain topics. I have a script I create before I added the datarelations.
I know how to alter the web config to redirect to an errors page but what I need to do is have the actual offending error message print to that page. This is a special request for testing reasons, I realize the whole point of a custom error page is to provide a user friendly message when an error occurs but for testing we want to show the user the message so they can copy and paste it into a ticketing system we are using for beta testing feedback.
Should I use the global.asax instead? I am pretty new to vb.net and am not sure how to get the actual error message to display on my custom error page.
I have a datalist in my site which displays html tables filled with data from a sqldatasource. I need to be able to remove one column from the table and put it back again (including the tags in my table which pull the data from the datasource e.g. <%# DataBinder.Eval(Container.DataItem,"Forecast1") %>) I need to be able to do this because I have options to change the sqldatasource query, and I need to alter the table to keep it compatible with the query. What is the best way to do this?
