- ASP.Net >> Change Password Control HelpI added a change password control to my application and when I run the page
that has it, I get an error:
Generating user instances in SQL Server is disabled. Use sp_configure 'user
instances enabled' to generate user instances.
Not sure where to start for this error, because all the code in the
code-behind runs. It seems that when the page is about ready to display, this
error comes up. I saw references to membership stuff in ASP.Net 2.0, but we
are not using that...yet.

- ASP.Net >> anyone upload code to load balanced servers?I'm wanting to get rid of a hardware load balancer and just use the Windows
2003 software load balancing with 2003 Server Web Edition.
I'm wondering if anyone here uploads ASP.NET code to 2 or more servers that
are load balanced by Windows Server Network Load Balancing (software load
balancing on Windows 2003). If so, or if you're sure of the answer anyway
for windows-based load balancing, here's the questions:
Can you do just one upload that updates code on all the web servers at once?
Do you just specify the NLB IP address?
Can you choose to upload code to just one server first, make sure it doesn't
cause major problems, and then update the other servers one-by-one? Do you
just specify each machine's non-load-balanced IP address?
If you manage the NLB software side of things, do you find it easy and
reliable?

Specifically, I have a checkbox for a column of bit datatype on my database,
and I'd like to default it to checked for insert of a new row.
Thanks,

- ASP.Net >> Databinding a Multi Column List?I need to databind a record set from the database into a page.
The output I need is a textbox and a label for every item in the
resultset, but I don't want a long vertical list... instead I want a
table with 3 or 4 columns, with each cell holding a textbox and a
label.
So if I were to bind this to a datagrid, the default view would be a
tall and narrow grid, but what I want is more of a rectangular shape on
the form.
Anyone know if this type of thing is possible?

- ASP.Net >> Displaying External Web Site via IntranetWe have approximately 90 computer users, but only 13 have internet access,
the rest are not configured to browse the internet. We want to display
certain web sites to all users without reconfiguring their pcs. Is there a
way to have our intranet web server retrieve the external page and then
display the results to the user?
Thanks.

- ASP.Net >> ASP.NET 2.0 - ViewState not working???I am testing ViewState in a C# ASP.NET site. The following code SHOULD cause
the values of the variables to increase whenever the user pushes the submit
button - but this is not happening; instead the values are getting set back
to their initial values set at page_load. Someone please tell me what I am
doing wrong!
Here is the code:
public partial class _Default : System.Web.UI.Page
{
Int32 Counter;
string StringVar;
double DoubleVar;
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
Counter = 1;
StringVar = "Hello";
DoubleVar = 3.5;
ShowCounter.Text = Convert.ToString(Counter);
ShowStringVar.Text = StringVar;
ShowDoubleVar.Text = Convert.ToString(DoubleVar);
}
else
{
Counter = (Int32)ViewState["Counter"];
StringVar = (string)ViewState["StringVar"];
DoubleVar = (double)ViewState["DoubleVar"];
}
}
void Page_PreRender(object Sender, EventArgs e)
{
ViewState["Counter"] = Counter;
ViewState["StringVar"] = StringVar;
ViewState["DoubleVar"] = DoubleVar;
}
void PushMe_Click(Object sender, EventArgs e)
{
Counter = Counter + 1;
StringVar = StringVar + "!";
ShowCounter.Text = Convert.ToString(Counter);
ShowStringVar.Text = StringVar;
ShowDoubleVar.Text = Convert.ToString(DoubleVar);
}
}

- ASP.Net >> Usage of "Request.UrlReferrer"I've got \\root\folder\Page2.aspx that I want to controll
access to, by establishing a rule that says "previous URL
must be '\\root\folder\Page1.aspx' (which did password
validation). The code snippet below does 1) allow valid
Page_Load if referring URL was 'Page1', and 2) disallows
Page_Load if the *initial* access attempt was PRIOR to
any valid load of 'Page2'...
<code>
// In Page_Load...
// check the prior URL and make sure our access
// came from the correct first page.
//
bool bBadRef = false;
System.Uri referrer = Request.UrlReferrer;
if (referrer == null)
bBadRef = true;
else
{
string csRef = "NONE";
string csRefPath = "NONE";
try
{
csRef = referrer.AbsoluteUri;
csRef = csRef.ToLower();
csRefPath = csRef.Substring(csRef.IndexOf
("folder"));
}
catch (Exception refxc)
{
throw new Exception(csRef);
}
if (csRefPath != "folder/Page1.aspx")
{
bBadRef = true;
}
}
if (bBadRef)
{
this.Response.Close();
return;
}
</code>
PROBLEM: If *after* I accomplish a valid access to Page2
(i.e. via Page1), then browse to a completely different
unrelated web page, I am then able to *directly* plug the
Page2 URL into my browser Address field and validation
does NOT fail! Could this be due to some kind of
caching effect that I'm not taking into account?
I'm rather new to aspx, so consider this a 'newbie'
question! Thanks!

- ASP.Net >> How to get a list of only the files on an ftp serverI want to get a list of the files in an FTP folder. I have seen the example
of MSDN using the FtpWebRequest, and it's fairly trivial to execute an NLIST
command, but the trouble is that this includes directories too. I can
specify a pattern like *.* in the uri to exclude directories, but this then
does not return files without extensions and there may be some of those.
If I use LIST instead, I can tell the directories as they get tagged with
<DIR> in the results. i.e.
02-15-07 12:21PM 488 Fred.xml
02-15-07 12:21PM 488 Gary.xml
02-15-07 12:21PM 488 James
03-16-07 10:19AM <DIR> Kathy
03-16-07 11:19AM <DIR> Louise
But I'm not sure that I can rely on the filename always starting at the same
offset from the start of the line which makes parsing the results tricky.
From a google on the web, it looks like there's no defined standard for the
response to a LIST command so I don't want to rely on the layout of this.
I could use both calls and read the directory names from the results of LIST
(whatever followed a <DIR> tag) and then remove these names from the results
of a call to NLIST, but I'm wondering if there's a simpler way.
Cheers,
Bill

- IIS >> Can't Get Website's PropertiesI downloaded a new reference file for AD-Aware and used it on my computer. It came up with 76 things and i didn't think to check them all cause i trusted ad-aware not to delete things i needed. Well it deleted some IIS stuff that I needed.
I deleted the backups too, dont ask me why.
I've uninstalled and then re-installed IIS completely. And when i goto inetmgr and try to get properties on the website, nothing happens.
I right click, and hit properties and nothing comes up.
I can't change anything :( what do i do?

- ASP/Active Server Pages >> Format(string.......etcAnyone able to tell me if there's an alternative to the Format function that
VB has? (it appears ASP doesn't support it)
I'm basically (and believe me, I know how stupid this is going to sound)
trying to find a way of getting a file/folder's size to show in something
other than bytes (i.e. KB or MB, depending on what size it is).
I've tried modifying some of my VB functions to ASP compatable, but it
doesn't seem to like them.
E.G. in VB, I use;
something = Format((Fldr.Size / 1024), "#0.00") & " KB"
or
Format((Fldr.Size / 1024) / 1024, "##0.00") & " MB"
Neither of the above seem to work as below;
Response.Write Format((Fldr.Size / 1024) / 1024, "##0.00") & " MB"

- IIS >> A tool to open and view a metabase file?Apologies if this has been answered before, I did do a search but I had no
luck in finding an answer.
Is there a utility out there which would allow me to take a backup copy of
the metabase from one computer, and open it on another computer to examine
the settings and configuration of IIS?
I tried the metabase editor from microsoft, but I could not find a recent
version. The copy I found (v2.2) is buggy and had problems running on my XP
pro. Anyway, I don't think Metabase Editor is going to really do what I
described above.
If anyone knows of a tool that I could use, I would appreciate hearing from
you.
Thanks alot in advance.

- Frontpage Client >> interactive picture uploadMy web designer said that this couldn't be done...but I can't believe it. I am a hat maker and I want my website to be more interactive with my customers. I love using FP and will probably never use all of its functions but there must be a way to let my clients upload a picture of themselves and then drag one of my hats to their picture so they can virtually 'try on' one of my hats to see how it would look on them. I've already had them send me pictures and I have put the hat on them and sent it back. I would love for them to be able to do this on my site. Can this be done? Is it possible without being a Fortune 500 company? I am a competant amateur when it comes to graphics but I would rather make hats than learn any complex coding. I also have a very cooperative and cool hosting company but I don't know what I need to ask them. Can anyone help me?

ASP.Net >> Sort list via client code only
H
I have to display a sortable list of columns(a table or so) - by click on the title of a column the column would be to criteria to sort by
I know datagrid is very conveniant, but I want to save the round trip to the server
Is there other way to use ASP.NET server controls(maybe the datagrid itself) to have an easy databound from one hand and client sort from second
May be a technique that tranform a XSL on datagrid result
For now all I could think of is to send XML to the cliend using response.write like with traditinal asp, and transor
a different xsl via the client DOM
I would be glad to here better suggestion to save the round trip
If there aren't , I would be glad to be noted on a good article that explains how to implement the XML/XSL technique
thank

Can someone please point in the right direction.
I have an XML file that gets updated every 4 hours on a web server.
I can check the XML modification time in ASP and compare to the

If it is newer, I need some ASP code to then import the XML into

Been trawling the net for an answer for a while - no joy

- ASP.Net >> Firefox and Javascript location problemI've been working on making my ASP.NET web apps compatible with Firefox (the
uplevel configs for web.config are a real help).
However, one really weird thing is a GotoAnchor() function I have (server
side), which injects javascript along the lines of:
location = '#buttons';
I use this so that, following postback, I can just back down to the relevant
part of the page.
It works fine in IE, but not in Firefox! Furthermore, I seem to loose other
Javascript injected following it (it's not simply malfunctioning, it's not
rendered by .NET!).
Any ideas why this is happening? Maybe a second postpack?
I can work around it by only emitting the javascript with IE - it's not the
end of the world. But a way to get similar functionality on Firefox would be
great.
Thanks,
John

- Frontpage Client >> is a custom form handler what I needHI - I'm looking for a way to make a page with a form on it so that when you submit with a predefined correct answer, you go to a "correct" page, or to an "incorrect" page if your form input does not match.
I'm doing this to add a layer of security to a personal website so that only people who know me can access certain pages. I thought I try to do this by reffering to a page with a few questions in a form on it.
When they click sumbit, I'd like for the server to check to see if the answers match up to the correct values. If they match up, I'd send them to another page in a subdirectory. If the are incorrect, they would be sent to a "sorry, but..." kind of page.
Anyone have any thoughts if a form and custom form handler is the easiest way to handlel this? I have a web site hosted by a comercial web hosting company.
thanks much,

- Frontpage Client >> Not Read: Message in errorI am experiencing a problem in Outlook/Exchange when a 'Not read - message
deleted without being read' return receipt response is getting generated from
a Inbox that is being processed by a program that reads emails using CDO, and
moves the email to another folder and marks it as unread. This results in the
'deleted without being read' message going back to the email sender. The
Inbox is also monitored by several users through Outlook. Since the message
is actually never deleted, we should not be getting this message returned.
Anyone else experience this and have any solution?
