- ASP.Net >> combination of SiteMap and cookieless sessions/forms based securitHi All
I've already posted this on the forums, but thought I'd try for a wider
audience as well. I've added cookieless security to my ASP.NET 2.0 site. The
URLs are rewritten to include the cookies for the Session and the Forms
authentication token. However, the URLs driven from the Web.sitemap file are
not modified.
Questions:
1. Is this a bug?
2. Is it a know bug?
3. What's the workaround...

- ASP.Net >> Visual studio 2005 HTML design view bugsHi,
I have had a lot of problems getting web pages, master pages and
content pages to render in VS2005 design view the same as they would in
Internet Explorer. I did a lot of looking on the internet for answers
but didn't have much luck. Anyway I believe I have found the causes of
the problems and thought I should share them in case any one else is
feeling the pain and also to find out what other peoples opinions are,
on whether these are bugs with VS2005 that should be fixed by
Microsoft.
******************************************************************
1. CSS incorrectly applied to Content and ContentPlaceHolder controls
VS2005 incorrectly applies CSS styles to asp:content and
asp:contentplaceholder controls in design view. As a result the design
view does not accurately display what will be rendered in the browser.
To recreate this problem do the following:
1. Create a simple stylesheet file called test.css
2. Place the following in the CSS file
td {
font-size: 25%;
background-color: #0AAE8B;
}
3. In VS2005 create a MasterPage with a single ContentPlaceHolder and a
<link> to the CSS file <link rel='stylesheet' href='test.css'
type='text/css'/>
4. Create a content page based on the created MasterPage
5. put some text in the in the asp:content control
6. Run the content page so that it can be viewed in Internet Explorer
7. In VS2005 view the content and MasterPage in design view
In VS2005 design view both the asp:content and asp:contentpalaceholder
have a bluish background and small font. However, when you run the
page in Internet Explorer the text is normal size and the background is
white.
I believe that this problem may be happening because the asp:content
and asp:contentplaceholder controls are being rendered as <table> for
display in VS2005 design view but they are not rendered at all when
output to Internet Explorer
This bug means that developers cannot see what the page will look like
without having to run it in Internet Explorer. It is possible to work
around the bug by modifying the <td> entry in the CSS file but the
problem with this is that the CSS file is set by the Marketing and web
teams which means it is not easily changed and if changed may break the
look and feel of older web apps.
**********************************************************************************************************
2. Comments affect the display of the page
Putting a comment in front a <!DOCTYPE> tag causes the page to render
differently in Internet Explorer as opposed to VS2005 design view
To recreate do the following:
1. Create a simple stylesheet file called test.css
2. Place the following in the CSS file
body
{
font-size: 25%;
}
.ApplicationName {
background-color: #0F4E8A;
font-size: 400%;
color: #FFFFFF;
}
3. In VS2005 create a web page.
4. Put in the following <link> tag. <link rel='stylesheet'
href='test.css' type='text/css'/>
5. Put in the following tags
<table>
<tr>
<td class="ApplicationName">
aaaa
</td>
</tr>
</table>
6. Add the following comment after <%Page> but before <!DOCTYPE>
<!-- This is a comment that should affect nothing -->
7. Look at the page in VS2005 design view and then run it so that it is
viewed in Internet Explorer.
a. Notice that the text when displayed in Internet Explorer is much
larger than when viewed in VS2005 design view.
8. Move the comment below the <!DOCTYPE> tag
9. Look at the page in VS2005 design view and then run it so that it is
viewed in Internet Explorer.
a. Notice that the text is now the same when displayed in Internet
Explorer and VS2005 design view.
VS2005 design view and Internet Explorer 6 handle the html comment <!--
This is a comment that should affect nothing --> differently. I am not
sure which one is handling it correctly, but one of them is definitely
wrong.
*********************************************************************************************
3. CssClass property of ASP controls is not accurately displayed
VS2005 design view does not render a page in the same way as Internet
Explorer when an ASP control with a "CssClass" property is inside a
html tag with a "class" attribute.
To recreate do the following:
1. Create a simple stylesheet file called test.css
2. Place the following in the CSS file
.ApplicationName {
background-color: #0F4E8A;
font-size: 200%;
color: #FFFFFF;
}
3. In VS2005 create a web page.
4. Put in the following <link> tag. <link rel='stylesheet'
href='test.css' type='text/css'/>
5. Put in the following tags
<p class="ApplicationName">
<asp:Label ID="Label1" CssClass="ApplicationName"
runat="server" Text="ApplicationName"></asp:Label>
</p>
6. Look at the page in VS2005 design view and then run it so that it is
viewed in Internet Explorer.
a. Notice that the text when displayed in Internet Explorer is much
smaller than when viewed in VS2005 design view.
It appears as if VS2005 design view is applying both the style
specified in "class" attribute and the style specified in the
"CssClass" attribute so that the text "ApplicationName" is displayed at
400%. Internet Explorer, however, applies only one of the styles so
that the text "ApplicationName" is displayed at 200%.
Once again I am not sure if it is VS2005 or Internet Explorer which is
correct but one of them is definitely wrong.
Thanks,

- ASP.Net >> Growl- frustrating - update function DOESN'T DO ANYTHINGI am feeling frustrated and I am willing to bet its something stupid but I
could really use some help.
I have a class called anEvent. On my web form I have a button which creates
a new anEvent and loads the form data into the new event. It then sends that
event to a class function to try and update the data in the database. When
I hit the button, it appears that nothing happens, no error message, just a
return to the previous state of the controls. I have tried catching errors,
using try - catch to see if something is failing somewhere but have gotten
bascially nowhere. I have tried simplifying the query so much that its
"update tblevents set eventname= @eventname where eventid=@eventid" and
still nothing happens. Please help if you can. Thanks in advance!!

- ASP/Active Server Pages >> Windows 2003 Server ASP extensions not recognisedHi,
I have two servers, both running windows 2003 and both containing the exact
same properties for IIS.
I have a set of asp intranet pages that are located inside the
c:\inetpub\wwwroot\test folder.
On one of the servers, the asp pages run fine, however on the second server
the asp files are not recognised as asp pages. If you double click them,
windows pops up a message box stating "Windows cannot open this file".
If I try to view an asp page via the browser, I get page not found.
I have IIS installed, and under Web Service Extensions I have allowed every
item that can be set.
Does anyone know why windows cannot make an association with the asp page?
Many thanks.

- ASP.Net >> Sharing a ValidatorI have a form that contains a number of fields, all of which have
validators. There are two submit buttons, one to update a record and one to
add a record. Because the only difference in validation is to make sure
someone is not using a username that is already in use, I would like to be
able to use all the other validators for both the add and update buttons.
However, because as far as I know a validator can only be in one
validationgroup, that does not help me (although if they haven't already, I
think it would be a great improvement for the next version of the .NET
framework). Does anybody have any suggestions on a good way to solve my
problem (having 2 copies of each validator would work and be very simple,
but I would hope for a more efficient way)? Thanks.

- IIS >> HTTP requestI need some basic insight into the workings of a HTTP request and a
HTTP response. i'am using ASP.net.
1. what happens when a request is sent and the user clicks the STOP
button of the browser.
a. does the request goes through to the server?
b. will any server-side code gets executed?
c. if there is any database operations, will they get executed?
the scenario here is that, there is a online shopping site which does
credit card processing with database updates.
There is a possibility that the credit card transaction goes through
before the user hits the STOP button and the database updates does
not. The end result will be stale data! Please guide.
Thanks in advance.

- ASP.Net >> Detecting Downlevel BrowsersIn an ASP.NET 1.1 Web application, how can I detect - with *reasonable*
accuracy - whether any particular browser is a downlevel browser?
My objective is to insert a different menu (different User Control
containing a different menu) for downlevel vs uplevel browsers.
This is very important as I have a great DHTML menu - but on many MACs, it
doesn't work even though the vendor claims to cater to downlevel browsers.
So I'm going to generate my own menu for the downlevel browsers and need a
way to determine when to send down the simpler (downlevel) menu vs the super
duper DHTML menu.
Please note that I'm already aware that some geeks out there can force their
old or non mainstream browsers to pretend they're IE (via header mods): but
I'm not at all concerned about them. I'm more concerned about old grandmas
with old computers running old browsers (or running iMacs).
Thanks!

ASP.Net >> window.close in vb.net??
Vb.net is a server-side technology. window.close() runs on the client. The
direct answer to your question would be:
keep calling window.close() on the client side, there is no equivalent in
vb.net.
If your next question is how the server side vb.net program can get the
client-side call window.close(), look at this article:

There is no equivalent - VB.NET (and C# etc) runs server-side, so has no
native ability whatever to open and close windows etc...
However, server-side code can stream client-side JavaScript which can do
this...

- ASP.Net >> Publishing my webpageHi,
I've read many articles about publishing and problems with it, but nothing
about my problem.
I've written a website in VS2005 and it uses the internal webserver.
I do that at home at my own computer.
The website is an intranet site and must run on the company webserver
running IIS.
I publish the website in a folder on my pc and then email the files from
that folder to my company emailaddress. (no direct line available)
From there I write those files to the server folder of my website.
But....when I start my homepage, I get an errormessage stating I should set
"customErrors" to "off" to see what is going wrong, but when I do that, I
still get that message.
The IT people of my company did install FrameWork 2.0 on the webserver, but
probably I'm still doing something wrong.
The question is what???
Please help.

- ASP.Net >> custom component across asp.net pages..I'm pretty new to .net stuff, but not new to programming (lots of vb, sql,
cold fusion, and some asp)..
I have a "middle layer" object model I created, that has all my business
rules and database access for an order entry system, starting with the Order
object, and other basic child items, like LineItems and PAyments under that.
This is being used in the vb.net front-end for normal users in the company,
but I'd like to use this for the web front-end as well in asp.net.
But I'm trying to best figure out where and how I keep the session data for
the user.
Scenario 1 - Use the object model in a passive way, where I use only
individual objects as necessary for "some" rules and db operations, and
after every web page I update data in a "shopping cart" table, and populate
the objects as necessary.
Scenario 2 - Somehow pass the Order object from page to page, which will
keep all data available, especially for those complex operation like order
totalling.
I would like to save some load on the sql server, and would prefer NOT to
have a db r/w every page access. Plus, I'm really after code reuse; but I'm
also looking for maximizing web performance.
Where do web services factor in? Is this a case where I take my "order
component" and turn it into a web service, or do I call it as just any
other object?
Thanks!
