Hi Ken
Im new to .NET, but not new to coding...
My suggestion:
1. Charge the customer more money for the new feature.
2. Collect all input up front before populating your DB or DataTable Object. Create a collection and use the rankings as keys to populated the collection. If the user tries to reuse a rank, an error will pop, which you can propagate up to the User Interface prompting for a unique unused rank. After everything is filled in, populate the DB from the collection.
- or -
You could just make the rankings part of the DB a unique field or primary key. I think this would also throw a catchable error that you can use to prompt the user to use a new rank.
Not sure how much this helps, I've done something similar in VB6 putting everything in XML, but you didn't leave a lot of details 
gl hf,

Sounds like a start. Basically I'm collecting all the data upfront. There's a simple aspx page that the user comes to. The user then has a list of items that s/he has to put a ranking next to: 1-9, 1-20, and 1-5. All three ranking sets have to be done on the same page (chairman's orders). Upon hitting submit, the information has to be sent to a database and so forth. Basically, I need to make sure each group only has numbers 1-9, 1-20 and 1-5. I'm thinking your way's sounding rather not too complicated. Any other ideas on top of it would be greatly appreciated.

I still rather like the idea of using collection objects for each set. You can use the "lost focus" and "validate" events (not sure what they are called in .NET) on the text boxes for entering the values into its respective collection. If the collection fires an error, return focus to the textbox and ask for a unique value
If you use combo boxes instead of textboxes you could be cute and remove the values that are already used from the blank combos, but this might make some user frustration as they try to change values after initially selecting them. Bah, go w/ textboxes ^.^

Hi,
I can't begin to understand this one. I have a form with a tabcontrol. When I first enter one of the pages (whether by tabbing or opening the form), I say to focus on a button. It does focus on that button but you wouldn't know it by looking at it (the dotted rectangle isn't there). I noticed that when the Tab key was pressed, the newly focused button will highlight, so when opening the form, I focused on the button next to the one I want focused and did a SendKeys.Send("{Tab}");. This works if the current tab page is the one in focus (I have another "screen" on that same tabpage where I can press an Exit button to return to the original screen), but it refuses to work when that tabpage is first opened - when tabbing into the page from another or opening the form. I'm completely out of ideas around this problem. Anyone know what I could do? 
Thanks so much for any help!!!

Your solution looks like a hack. Did you try setting the TabIndex property in the Designer to set the right Tab order?

Hi!
I'm looking for some help - i'm using the COM Excel Spreadsheet, Version 11 and actually i'm trying to set the borders of an cell. But it fails every time - i've looked around one day for a solution - nothing - i get something like that...
Property, indexer, or event 'LineStyle' is not supported by the language; try directly calling accessor methods 'Microsoft.Office.Interop.Owc11.Borders.get_LineStyle()' or 'Microsoft.Office.Interop.Owc11.Borders.set_LineStyle(Microsoft.Office.Interop.Owc11.XlLineStyle)
What does that mean - can someone provide some code for this...
i'm using Microsoft.Office.Interop.Owc11 - because the com object as well uses Interop and not excel...
Thanks...

It means you shouldn't be calling get_LineStyle() directly ... there should be a property accessor available called LineStyle (or maybe just Style) available from the Office and/or Excel Namespace.

<br />
NewRange.Select();<br />
<br />
NewRange.Borders[Microsoft.Office.Interop.Owc11.XlBordersIndex.xlEdgeBottom].LineStyle = Microsoft.Office.Interop.Owc11.XlLineStyle.xlContinuous;<br />

Use this...it works NewRange.Borders[Microsoft.Office.Interop.Owc11.XlBordersIndex.xlEdgeBottom].set_LineStyle(Microsoft.Office.Interop.Owc11.XlLineStyle.xlContinuous);
Good Luck

Hey there,
I'm working on a webpage using ASP and C#. At the server, I am tracking all of the live Sessions based on the HttpContext.Current.Session.SessionID value. As you probably know this is a value unique to each web browser accessing my pages.
Now my problem. I would like to know when a user closes the browser and leaves the site (assuming he/she doesn't "log out"). I am hoping to periodically check each SessionID to see if it is still current or expired. Is there a way to load a specific session based on its ID and check to see if it has expired or not?
If it matters, I am using cookies to store the session information.
Thanks in advance,
Pualee

P.S. -- Im reading a few books and looking all over the web, but having difficulty finding good information about Sessions (I'm new to Web Development). If you know a good online faq or tutorial, please share the love/url here

Unless you use javascript in the browser to tell the server when the user leaves the page, there is no way that the server can know when this happens. If the user doesn't log out, the server session ends 20 minutes (at default setting) after the last request.
Any information you store in a cookie is only available when a request is made, as the cookie is stored in the browser.

I'm not so much worried about the "event" of leaving, I just want to clean up some things periodically...
While still researching this topic, I have come across the following:
System.Web.SessionState.HttpSessionState class
.Count - Gets the number of items in the session-state collection
.Keys - Gets a collection of keys for all the values in the session-state collection
Shouldn't it be possible to loop on the .Keys to compare the active Keys against the keys my application believes are active? This might not be very scalable, but I'm not expecting thousands of users to connect per hour, this is a very specialized application.
I'm going to try this for now, but I'll be rechecking this board for feedback (never know when someone else has the same problem).
Also, would keeping the session data on server side, rather than as cookies, make this possible?

You may want to consider setting a short (< 5 mins.) session timeout on your app and have every page periodically (using JavaScript) retrieve a very small resource (eg: a 1x1 pixel transparent .gif) in an iframe.

Then use the Session_End event in global.asax.

You are confusing session objects with session variables. Each user has one session object that each can contain several variables. The Session.Keys property contains the keys of the variables that has been stored in the session object for the current user.
The server of course keeps track of the active sessions, but it doesn't expose this list to anyone. Probably because items can be removed from the list at any time.

That depends. What is it that you store in the cookies anyway?

Thank you for your interest, but (there is allways a but...) those methods require XP+ as an operating sistem (beeing dependent on WMI). This is exacly what I've founded myself.
I am curently looking for an other method, whitch should be suported on a 95-98-me-2000 operating system too, or two methods one for XP+ and one for the rest ...
Anyway, the WMI querry didn't returned the corect string, other programs gave me an other result.
Any further ideeas?
PS: Thank you for your help again...

Aaah, the same problem I had, although in my case the client wanted it written in VB6. this[^] is what I based my solution on. Sorry, it really is VB6, but it's largely calling onto the Win32 API so perhaps it'll get you started.

Oh that's easy.
using RG = System.ReportGenerator;<br />
<br />
ReportGenerator _generator = new ReportGenerator(new StreamReader(@"c:\sourcefile.txt"));<br />
_generator.OutputType = ReportTypes.Text;<br />
_generator.OutputType = ReportTypes.Html;<br />
_generator.OutputFile = @"c:\outputreport.html";<br />
_generator.Generate();

Hello,
Thank for your reply. It's very easy what you say, but i don't have the class System.ReportGenerator in my Microsoft .NET Framework 1.1. What framework you use? Or ReportGenerator it's a other class, not from .NET framework. If you fave this class, please send me (mihai@sln.ro).
Tranks,
Mihai
