As the title states, how can i stop two users from booking the same appointment time.
Example, two users logging, on there screen they can both see that a 1pm appointment is available. They both try to book themselves into that appointment time.
How can i stop this from happening and ensure only one user can book it, then refresh the screen to show the next available booking time to the other user.
I am beginner of asp.net and c#
Currently i am learning on create a website with appointment feature. The website i am doing basically a dental appointment web, which show the free slot of dentist on the website and enable patient to book appointment by schedule an appointment based on time and date given. I have done others thing such as register, login, report those however i have no idea on doing the appointment module. I am trying to learn easy way to create booking feature for dental website. Is that a tutorial on learning to do this or others way which i can easily learn it.
I have been trying to fix this issue for several hours now, and I was hoping to find out if someone can shed some more light on it. I get the above error on ONLY ONE virtual root in my IIS 5.1 installation. I have other web sites I am developing in .NET 2.0 and 3.5 and they seem to work fine. This is a development workstation with only 1 user, and I get this error continuallyevery time I access only 1 of my web sites - even after rebooting the machine. It makes no difference what order I access the web sites in - this one always fails and the other ones always succeed.
Note that the web site does not use frames and the changes I made to it yesterday (just adding some javascript and a few span elements to support BuySafe's new 3-in-1 guarantee program) were very minor.OS: Windows XP/IIS 5.1Dev Environment: Visual Studio 2005/.NET 2.0Browser IIS 7.0Every page on the internet I have read about this seems to indicate it must be something with the "HTTP Keep Alive" setting. I disabled this setting but it made no difference at all.I keep full backups of my machine and I restored my OS/IIS partition from a few days ago (including the full IIS metabase), but I still continue to get the same error.The error suddenly started occuring today - I just made some updates on the web site and deployed them to production yesterday (and neither my test or production servers are exhibiting this behavior). It happened after a power failure and my UPS software forced my Lenovo T500 laptop to sleep. When the power failure occurred, both VS 2005 and a browser with this web site were open on the machine. The machine woke up and the programs were all still running, but I was no longer to access this web site.I had a problem like this years ago and I ended up rebuilding the machine from scratch. Please give me an alternate solution.Full Error Message:The page cannot be displayedThere are too many people accessing the Web site at this time.Please try the following:Click the Refresh button, or try again later.

View 1 RepliesI have a question.aspx page that allows "guests" and "admin" to use. If guest access the page, it says Submit, if admin access it, it says "Approve" on the button control.
My question is, when guest accesses that page, I don't care about their credentials, but when admin accesses that page, I want them to log in first. And the Admin users are the ones that work in our company with the same domain and such. Anyone that access outside would be "guest".. how can I prompt people in the same network when they try to access that page? I need that AD credentials to do some programming in code behind.
Whenever I stop debugging an ASP.NET IIS web application it seems to take very long before VS2010 becomes responsive again (2 or 3 minutes). This happens when I close Internet Explorer 9 (which stops the debugging session), stop debugging in VS (which closes the browser) or when I detach the debugger from the debugging menu (which leaves the browser open).
My CPU time for devenv.exe goes up to 25% during this period of time. I use the professional edition (no intellitrace). Starting without debugging performs ok when I close the browser. I have some add-ins and extensions installed like TestDriven.NET, Resharper, PowerCommands, Productivity Power Tools, VisualSVN,...
I just recently installed VS 2008 on my workstation. I tried creating a simple web site just to check if the installation was fine. The project compiled without error but when I tried running it, the Macromedia Dreamweaver software is being launch. It tried it several time and it's all the same.I remember during the installation there was an option that was displayed asking me to select Designer or Coder. Since the default is Designer i just click next.
Is there a way to stop launching dreamweaver from VS 2008 every time i try running the web project? Is because I selected "Designer" during the installation?
I have a WCF service that processes some input arguments and retuns result in approximately 4 minutes. Sometimes the calling client may get request time out before the WCF service answers.
Now, my customer is asking me to stop processing on the service side when the client got timed out. Since, I could not know the status of cleint on the service, I could not stop the process.
When I will click on gridview cell then it should open a pop up aspx page on which appointment details will be asked that I will store in databse. So with javascript how can I do this ?
View 1 RepliesThis is a really odd situation, so hopefully I can explain it well enough.
I am deploying an ASP.NET 4 webforms application to a Windows Server 2003 SP2 server running IIS6.
Here's the problem -- when the application pool recycles its worker process (w3wp.exe), about 80% of the time, I will get an ReflectionTypeLoadException error trying to access any page in the app that contains an EntityDataSoure every time I try to view it.
However (this is the interesting part) -- the other 20%, it works just fine. I've actually resorted to turning off recycling the worker process entirely for this application pool and just add/remove whitespace from web.config forcing the site to recompile until I get a "good" w3wp.exe.
If this isn't clear, what I'm saying is: the actual worker process doesn't work at all for pages containing an EntityDataSource for about 4/5 times it starts, but still manages to serve all other pages just fine. Once you get a worker process that manages to serve a page with an EntityDataSource, it works every time until that process gets recycled.
My question is, how can I debug this? It works fine on my dev machine, it works fine on the server as long as you get a good process running, but iisreset or a server restart or anything that kills the worker process is almost guaranteed to cause the site to not come back up and throw this ReflectionTypeLoadException.

I am trying to create an outlook appointment from an ASP.NET web site version 2.0. I am making use of the interface Microsoft.Office.Interop.Outlook to create the appointment. But my exact requirement is to display the body (description) of the appointment in HTML format (which includes images, links etc) instead of plain text. The only methodI can see in the appointmentItem is 'body'. This method only writes the plain text not the formatted HTML body. So is there any alternate approach to format the description (body) of an appointment?

View 1 Replieshow this is achievable, not so much in the "build the whole project" as to how the reservation website gets quotes for all the flights from all the flight companies. I assume that in the website's code you have to use a webservice which will quote say website A, and get its ticket prices.

View 2 RepliesI would like to create a module that is similar to the inventory system but not with a whole lot of bells and whistles. Basically, I have a jumper business and would like create a database to hold the items (jumper, pop-corn machine, etc.). I would like to have a calendar that when a user click on a date that he/she like to book my item only the available items display and not the one that is already booked. Pretty much to prevent the same item to get book by two different people on the same date. I also would like to create a form on the order page to have the booking information to go into the database.

View 1 RepliesI have to adjust the existing travel booking form on www.lastminutejoy.de for all the 6 subpages which can be seen in the footer area (royal atlantis, aspendos beach...)
On a certain subpage, e.g. .../aspendosbeach.aspx, the visitor should be able tosearch ONLY everything related to aspendos beach. The style should be like this one: www.delphinpalace.de (on the left)
There you can see that you can search for "flight + hotel" (Flug + Hotel) and "hotel only" (Nur Hotel).
As a result of the search, visitors should see the same style like the one you see on those subpages of lastminutejoy.de.
As you don't have to code from scratch but just have to do some adjustments for all 6 hotels this shouldnt take too long.

View 12 RepliesWe're debating on the architecture of this university database project. We can't decide if we should relate the tables as -> "one person to many addresses" or "many persons to many addresses". We understand that there will be duplication of some data in the "one_to_many" schema. How bad would that be. "many to many" is obviously more normalized. Are there any trade offs for either setup? We expect there to be 100,000+ people.
