- ASP.Net >> Dynamic Table Control placementI have 2 Table Controls generated with Visual Studio .NET. I dont know how
big the first one will be until after page load (this page is called from
somewhere so the tables rows/columns vary each time). So I need to place the
second one below the first one automatically. Plus I'll also be place a
couple drop down lists, buttons, etc below the first one.
Any ideas of how to do this? Right now,I cant get the second table to move.
Note: i tried building a table in my HTML and placing my 2 server asp.net
controls in between but that didnt work

- ASP.Net >> New 2.0 Menu control. Opinions and resources welcome.The new ASP.NET 2.0 Menu control seems to have some very cool features.
But there are some things I don't like. Heavy implimentation of
inline style. Some of which I cannot remove. The <a> tags all
implement style="cursor:text". The stylesheet in the header begins to
get larger and larger as you create a more complex menu and apply
styles.
I like the menu archatecture but what I want to do is two things:
1. REMOVE ALL STYLE DEFINITIONS WITHIN THE PAGE.
2. REMOVE ALL INLINE STYLES WITHIN THE MENU.
It would be also nice to:
3. REMOVE ALL INLINE EVENT HANDLER DEFINITIONS.
eg. onmouseover="Menu_HoverStatic(this)"
So far I only see my options being re-writing the entire control
hopefully inheriting from it and reusing as much functionality as
possible. The rendering of the menu is somewhat black box and I'm not
sure what all goes on during the OnPreRender method. I know that if I
override the OnPreRender without executing base.OnPreRender the style
definitions for the Menu control disapear. GREAT! That takes care of
#1, but what else does it mess with. :(
Any help would be great. But if anyone feels that this is just too
much effort in hopes of cleaning up HTML, I'd love to hear it.
My experience with building high traffic websites has put me in the
belief that every byte counts and any possibility of removing
unneccesary code should be explored
Note that what I intend to do is use class="[name]" to apply all styles
and apply behaviors (onmouseover, etc) by parsing the document tree and
applying the event handlers, etc, etc. I'm already doing this with
other websites.
Again, any help, resources, or opinions welcome.

- ASP.Net >> Session abandon. New page loaded but not new SessionIDMy web application is comprised of a Login page and then several other pages
nested in a masterpage. I am using a cookiless="UseUri" session configuration.
I have a linkbutton on the masterpage for logout and when the user clicks
this, code is run that does Session.Abandon() and Server.Transfer("Login.
aspx"). This runs fine, but the url still reflects the old SessionID. Because
of this, if the user decides to login again, the page reloads back to the
login page after entering his information. This reloads the new sessionID and
works from there. Is there a way to stop the 2 page loads of the login page
after the session is abandoned?

- ASP.Net >> Disallow download of certain file typeHi. I can't place an mdb database above the http root, so anyone is
able to download it through their browser if they know where it is.
This database contains some sensitive information. I am used to Apache
server and open source languages, I think web.conf is sort of
equivalent to Apache's .htaccess, is there some way I can edit
web.conf to disallow access to mdb files?
I'm sorry if this is not the exact group I should be posting in, but I
don't know where else to post. I am developing the application in
ASP.net, so I figured this would be an appropriate place.

- ASP.Net >> ASP.NET 2.0: Are they going to fix HtmlSelect?HtmlSelect has a method called OnServerChange that supposed to detect
whether the control (select) has changed on a postback.
This is not all that useful.
It should be like the asp.net control, DropDownList, that initiates a
postback when the option, AutoPostBack is set to true...so you can either
have it postback when the user changes it immediately or not do anything
when the user changes it.
Seems like a very easy thing to do..if you are going to set the
OnServerChange or OnChange, it should know whether or not you want a
postback OR if you want client side JavaScript to handle it.
Any comments from the ASP.NET team......

- IIS >> Unable to install IIS with windows server 2003 R2 with SP2 trial versionI am Ritesh Mehta. I had registered for a free 180 trial of windows
server R2 2003 with SP2.I was given 2 image files(I had to download)
to setup the OS on my machine.After setting windows server I tried to
install IIS by going to Control Panel-->Add/Remove Prog--->Add/Remove
Windows Components and selecting Application server.But it does not
allow me to install. It gives a prompt to insert the disk labelled
"Service Pack 2 CD-ROM". It says some files in this CD are needed.The
problem is that the two disks that I burnt were images which were
converted to .ISO's to make it bootable and hence it is unable to find
those files. I dont know what do I do.It should not be giving this
prompt as the two images had the SP2.Any help would be greatly
appreciated as I need to install IIS o my machine.

- ASP.Net >> ASP.Net 2.0 - how to add custom style into page headerHi,
What is the "right" way to create the following css rule in a page header:
<style>
.myRule{text-align:right;padding-right:10px;}
</style>
I know that you can add simple styles as follows:
this.Page.Header.StyleSheet.CreateStyleRule(style, this.Page,
".mySimpleRule");
but then I am not sure how to set text-align, padding or similar styles to a
System.Web.UI.WebControls.Style object
I am trying to avoid putting literal into my header and altering its content.
Any help is appreciated.

- IIS >> secondary ip address?I have a windows 2000 server with IIS (stopped) and a Apache web server that
is running (for some Oracle functionality).
Now I want to install SUS for Automatic updates of my LAN, but IIS cannot
start because the IP address an the port 80 of my server are binded to the
Apache web site (I cannot modify this configuration!).
How can I solve this?
I read that I can assign a secondary IP address to the server and run IIS
with this address. Is this correct or there are better solutions?
Thank you in advance!

- Frontpage Client >> Images wont stay next to each other with space in codeHello, I know I'm not a html expert but I thought that spaces in coding had no affect on layout of content. When I put all my slices together and set them to have javascript swaps,restores,and preload the code got very long and FP put it all on one line so I put each individual image on a seperate line.the code is below but just imagine the last lines were one line and almost identiacal lines below it. Only FP put a single space between each image. Very frustrating. Please help. Matt

- ASP.Net >> Anyone know of a good HTML editor control with a free version?Hello,
I am looking for an HTML editor control. At this stage, I only really
need a very basic one, I don't need all the skins and customisation that
many of them seem to offer. I would also like one that I can use a free
version without it timing out. That way, if it's any good, I can buy a
full version if the extra features are worth it.
Anyone any recommendations? I looked at FreeTextBox, but I couldn't get
it to work, the documentation is almost non-existent and they never
bothered answering my request for support!!
I looked through the control gallery at www.asp.net, but there are so
many controls there it's hard to know where to start.
Any suggestions welcome. TIA

about 10-20 virtual directories. One of these sites is killing the
machine. What happens is all of the sites go down (or slow down) and
the aspnet_wp.exe process is sucking up alot of memory. (650 MB+) I
need to find out what site is causing this to fix the code. What can I
do to go about isolating this problem?

- ASP/Active Server Pages >> Forums for aspfaq.comWhat do you think about having discussion forums on aspfaq.com?
(a) Would you use them? Not as an alternative to these groups, but as
another place to discuss issues?
(b) Would your answer to (a) change if you had to register (for maintenance
and lock-out/abuse purposes)?
(c) Do you have any preference as to how the site could be self-sufficient?
e.g. would you be willing to pay a lifetime membership fee, or put up with
banners, or ... other ideas ...? I know there are free venues out there,
and nobody likes to pay for anything, but I also know that people will pay
(or put up with advertising) for useful information and/or a more usable
interface.
I'm building a forums module for another project, and it has been an
often-requested feature for my own site. However, the bandwidth and
database usage comes at a price, and I don't think I could justify footing
the bill out-of-pocket (since the site itself derives $0 in revenue). I
would certainly consider making the service cost- and banner-free if I can
get any suggestions on how to make the site support itself.
Thanks for any input,
Aaron

- IIS >> A very strange Permission Denied error with CDONTSI've seen a lot of postings regarding this error, but haven't found
any solution applied to my case. In our application, a user will get
two emails. One is the email with password after he signs in; and
after he finishes certain transactions, a second email will be sent as
confirmation.
Both emails work fine in our development, but in production, only the
first email works; the 2nd generates the Permission Denied error when
the send() function of CDONTS.NewMail is called. Since the first email
has always been sent out successfully, there shouldn't be any problem
with the mailroot directory or SMTP server on the production. The
send() of the first email is called in an asp file, and the 2nd is
called in a DLL. The asp and the DLL are placed in different folders.
I compared the rights of the two folders, and also compared the
folders between the development and the production, and I can't find
anything different.
Both development and production run on Windows 2000 server with IIS 5.
We don't use Exchange server. The only difference that I know of
between the two servers is the development has SP4 while the
production has SP3.
Does anyone have suggestion on which directory the permission may be
denied for? Thanks in advance!

- ASP/Active Server Pages >> SQL Where <> help with syntaxHi
I am fairly inexperienced with ASP, SQL and VB Script.
In one of my web pages I am trying to search a table in access which
has a number of integers (GroupID's) (1 to 5 at present) and find those
which do not match another set of GroupID's already contained in a
record set named rsGroupsJ (1 to 4 at present).
I want to find the GroupID's which do not match ie GroupID
I have created the following sql which returns the error:
"Unterminated string constant"
strSQL3 = "SELECT tblGroups.* FROM tblGroups WHERE tblGroups.GroupID <>
(rsGroupsJ("GroupID"))"
The following sql does not create an error message but the WHERE bit
seems to be ignored - it returns all records 1 to 5, it should only
return 5
I am realy poor at creating sql statements, I am never sure where or
why to put " or &
I have looked at a number of tutorials but cannot find examples close
to my requirements.
Any help with this would be appreciated

- ASP.Net >> HTTPModule in a sub-directoryI have created an HTTPModule for error handling, which I only want to handle
a specified directory structure. In the root of my application, I have
altered the web.config file as follows:
<configuration>
<location path="dir/dir/dirToHandle">
<system.web>
<httpModules>
<add name="ErrorHandler" type="ErrorModule.ErrorHandler, ErrorModule" />
</httpModules>
</system.web>
</location>
<system.web>
...all other settings such as compilation, customErrors, sessionState,
etc...
</system.web>
</configuration>
For some reason the HTTPModule is behaving as if it doesn't even exist. Is
the location element not setup properly? If I remove the location element
and put the httpModule element into the other system.web, everything works
just fine.
