Regular expressions is the way to go. You need to escape all script, object, applet, embed and param tags, and remove any event handlers on other tags.
using System.Text.RegularExpressions;
...
static bool IsLikeRe(string src, string pattern)
{
return Regex.IsMatch(src, pattern,
RegexOptions.IgnoreCase | RegexOptions.Singleline);
}
static string ReReplace(string src, string pattern, string replace)
{
return Regex.Replace(src, pattern, replace,
RegexOptions.IgnoreCase | RegexOptions.Singleline);
}
static string ReReplaceAll(string src, string pattern, string replace)
{
string ret = src;
while (IsLikeRe(ret, pattern))
ret = ReReplace(ret, pattern, replace);
return ret;
}
static string StripScript(string html)
{
string res = ReReplaceAll(html, "<script(.*)>", "<script$1>");
res = ReReplaceAll(res, "</script(.*?)>", "</script$1>");
res = ReReplaceAll(res, "<(object|applet|embed|param)([^>]*)>",
"<$1$2>");
res = ReReplaceAll(res, "</(object|applet|embed|param)([^>]*)>",
"<$1$2>");
res = ReReplaceAll(res,
@"<([^>]+?)\son(?:[^>]+?)=(['""])(?:[^>]+?)\2([^>]*?)>",
"<$1$3>");
return res;
}

howdy all,
busy designing a new web application that would be perfectly suited to a webclass application.
ie. one template page that defines the layout and within that layout tokens to define where runtime generated content should be placed.
my question is this ...
how should we be doing this kind of thing in asp.net ?
should we build server controls and drop these onto the aspx pages ?
should we build one page that serves as a template and the other pages inherit from this ?
should we still use something similar to token substitution ?
please help, any ideas ... suggestions ... guidance would be hugely appreciated
cheers

Page Templates in ASP.NET[^]
ASP.NET is far more powerful in this manner than vb6 webclasses 
You can also use user/custom/server controls for this, but in reality you will find yourself using both technologies.

thanks ... i have been toying with some ideas, of which some are good - others seem better.
has anybody had experience in implementing this type of thing ? which method is best ?
i am currently toying with the idea of using a base class that all pages inherit from. this base class will use user controls to dynamically build their content at runtime. each page will then only be concerned with what needs to be placed in the content section, the base class will handle the rest.
is there an equivalent to visual inheritance in asp.net ?
cheers

Both... lol.
When you need a consistent "style" for a bunch of pages sitewide then use a template. But then in your template also make use of custom controls.
They are not mutually exclusive.

Not sure officially what visual inheritance is but Google has some links.

Hi, everyone!
When I use the following statments in JSP to
connect to DB2, I meet with a trouble,
--------
Connection con = DriverManager.getConnection(url, user, password);
--------
The error is:
--------
java.sql.SQLException: No suitable driver
at
java.sql.DriverManager.getConnection(DriverManager.java:543)
at
java.sql.DriverManager.getConnection(DriverManager.java:183)
... ...
--------
Here url is a String whose value is jdbc:db2://localhost/MYTEST
But when I change the value to
jdbc:db2:MYTEST, then everything is OK!
I do not know why. 
I want to know the format of the url of a DB2 database when
I want to connect to a DB2 database on a remote machine.
Cheers,

Alright this has driven me mad and I am sick of reading other answers which get 99% of the way there and then fall over at the last step for me. I am sure I am missing something fundamental, but simple, here.
Basically I have a custom/server/whatever control which dynamically adds controls to itself in an overriden Render method. It adds three controls; two image buttons and a panel. They all render fine and look lovely, but what I want is for an event to be fired when I click either of the image buttons. When clicked the image buttons will set a member var. of the control.
Here is the code so far with what the event handling which I thought would work:
using System;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ComponentModel;
namespace bluegrass.content
{
public class resourcegallery : WebControl
{
public string View;
<code>private void view_thumbnail_Click(object sender, ImageClickEventArgs e)
{
this.View = "Thumbnail";
}</code>
<code>private void view_list_Click(object sender, ImageClickEventArgs e)
{
this.View = "List";
}</code>
protected override void Render(HtmlTextWriter output)
{
<code>ImageButton imgViewThumbnail = new ImageButton();</code>
imgViewThumbnail.ID = "view_thumbnail";
imgViewThumbnail.ImageUrl = "res/img/view_thumbnail.gif";
imgViewThumbnail.AlternateText = "Click for a Thumbnail view of the Resource Gallery";
imgViewThumbnail.CssClass = "viewbutton";
if (View == "Thumbnail") imgViewThumbnail.Visible = false;
<code>imgViewThumbnail.Click += new System.Web.UI.ImageClickEventHandler(this.view_thumbnail_Click);</code>
<code>this.Controls.Add(imgViewThumbnail);</code>
<code>ImageButton imgViewList = new ImageButton();</code>
imgViewList.ID = "view_list";
imgViewList.ImageUrl = "res/img/view_list.gif";
imgViewList.AlternateText = "Click for a List view of the Resource Gallery";
imgViewList.CssClass = "viewbutton";
if (View == "List") imgViewList.Visible = false;
<code>imgViewList.Click += new System.Web.UI.ImageClickEventHandler(this.view_list_Click);</code>
this.Controls.Add(imgViewList);
Panel panelResourceGallery = new Panel();
panelResourceGallery.ID="ResourceGallery";
panelResourceGallery.CssClass="resourcegalleryview";
panelResourceGallery.Controls.Add(new LiteralControl(View));
this.Controls.Add(panelResourceGallery);
base.Render(output);
}
}
}
The event handling and relevant imagebuttons are highlighted.
So in short when either imgViewList or imgViewThumbnail are clicked client side I want the view_list_Click and view_thumbnail_Click handlers to be fired.
Please remember this is a custome control, not a user control (I can raise events fine in a user control, but I need the capabilities of a custom control.)
Thanks for any help

I assume it's not working because the scope of imgViewThumbnail, imgViewList and panelResourceGallery are all lost when you leave Render(). Thus all the EventHandlers will be destroyed when you leave the function.
Have you tried making panelResourceGallery a property of resourceGallery?

You are two inches from the answer. The answer is to do with the control life cycle rather than scope, but your scope idea twigged me to the life cycle bit. i.e. I need to be assigning the event handlers and everything else in the OnInnit method/event/function/whatever-the-right-label-is-but-who-really-cares-huh and not the Render. Render is done almost last, already past the event firing stage.

Thanks Paul.

I'd like to test my ASP.NET app with SSL to make sure all the links work etc before I publish it on the main site.
Can I get or generate a test SSL certificate for this purpose?
When I go to my main site I can use a shared SSL certificate (cheaper) are there any known problems with using Shared SSL and an ASP.NET app (codebehind). Or should I use a full blown one (more costly).
TIA

you can go to www.verisign.com[^] and register a "test" certificate. After a month they will email you and ask you to buy a proper one. Ignore them and carry on. We purchased one for our live server from them, but then needed to test the stuff on our dev server, so we did this. Our month has passed, but the test cert is still working nicely

When IE connect to a website using SSL,IE will display a dialog to ask user to select a certificate of him(or her).
In fact,IE connect to the system's CSP and search user's certificate.
my question is:
if my certificate is stored in other place,but not in the system's CSP or a SmartCard,how can I have IE use my certificate when it connect to a SSL website?
For example,I store my certificate(and private key) in my own USB card,which is not compatible with the SmartCard.What can I do?
I think that if I can hold up the event which occur when IE connect to the system CSP for requiring a user certificate(and private key),it will be simple!
thanks advance!

Hi all. I am very sad 
OK, I have the following HTML. A table with 4 rows, each row have variable cols and contains a table in the last column. Now my understanding is the the "inner" table should not affect how the outer table is "rendered". So what we have here is:
<table cellpadding=0 cellspacing=0 width=100%>
<tr><td colspan=3>
<table width=100% border=1>
<tr>
<td width=100px></td><td></td>
</tr>
</table>
</td></tr>
<tr><td width=15px></td><td colspan=2>
<table width=100% border=1>
<tr>
<td width=100px></td><td></td>
</tr>
</table>
</td></tr>
<tr><td width=15px></td><td width=15px></td><td colspan=1>
<table width=100% border=1>
<tr>
<td width=100px></td><td></td>
</tr>
</table>
</td></tr>
<tr><td width=15px></td><td colspan=2>
<table width=100% border=1>
<tr>
<td width=100px></td><td></td>
</tr>
</table>
</td></tr>
</table>
Now if you will kind enough to paste that in a blank page, you will see all looks well, especially when resizing the browser sideways. IOW the left hand "padding" TD's stays fixed. All happy, all OK. Btw, I use IE6 XP SP1.
Now change the the width attribute of the first inner table's TD from 100px to 150px. This shouldn't have an effect on the the outer table, yet when you now resize the browser sideways, the padding becomes relative. Now HTF is this possible? If you are still interested at this stage, try playing around with the other widths, you will see even stranger things happening, eg some rows are fixed and some are "variable".
Is it me or is this just the way it is? It makes tables very inflexable indeed. [edit] The same page with different widths for the TD's renders correctly in Mozilla 1.1 and Netscape 6.2.3, not in IE 5 however. IE 0 - NS 1. [/edit]
All help appreciated. Cheers.
