I'd like to run all my validation on a button click, rather than on a per control basis, but keep the red exclamation marks. Any idea how to do this?

Re: Problem in binding grid with XML(From DB) Not Active23-Dec-08 1:18 Not Active 23-Dec-08 1:18  Don't post the same question, even if th title is changed You have a number of options. You could store the document in a database table with the column of type text or xml and use an XmlDataSource object to bind it to your control. You could also store the content of the xml file as individual columns in a database table and bind your grid to a datatable. only two letters away from being an asset Re: Problem in binding grid with XML(From DB) nileshbahirshet23-Dec-08 2:07 nileshbahirshet 23-Dec-08 2:07  Thanx buddy, but i have still some issue..

How can I do this ? setting WebRequest timeout vernicht22-Dec-08 9:20 vernicht 22-Dec-08 9:20  My objective is to get the answer from up to 6000 Urls in the shortest time. It was working very well (12 seconds for 5200 LAN Addresses) until some delay started to happen. My code uses up to 20 simultaneous HttpWebRequest.BeginGetResponse with ThreadPool.RegisterWaitForSingleObject for timeout handling. However some (up to 4 in 5,000) of the requests never hit the TimeoutCallback function with the second parameter (timedOut) true, and they waste 5 minutes of my precious time until they hit theBeginGetResponseCallback function and then raise a WebException. The exceptions says something like "the operation reached the time limit", but as the exception message is in portuguese(my native language) I couldn't Google it. I wonder if I can reduce this time limit to 20 seconds for example. Anyone knows how? I've already tried: <system.web> <httpRuntime executionTimeout="20"/> </system.web> But as I'm running it as a Console Application, ASP.NET configurations don't work. And I also tried: myHttpWebRequest.Timeout = 20*1000; And ThreadPool.RegisterWaitForSingleObject(result.AsyncWaitHandle, new WaitOrTimerCallback(TimeoutCallback), AsyncState, 20*1000, true); Without success. Can you help me? What I am trying to say is there are 4 possible results for an asynchronous HTTP request: 1) Never reach the callback function -> timeout callback function 2) Reaches and answers sucessfully 3) Reaches and raises an exception 4) Delay exactly 5 minutes until raise an "time limit" web exception inside the callback function The 4th possibility is the one is driving me nuts Assembly version numbers Not Active22-Dec-08 3:17 Not Active 22-Dec-08 3:17  MSDN[^] documentation says [assembly: AssemblyVersion("1.1.*.0")] is valid However, when I try this I get a compiler error; 'The version specified '1.1.*.0' is invalid' Does anyone understand what's going on here? only two letters away from being an asset Re: Assembly version numbers Pete O'Hanlon22-Dec-08 3:35 Pete O'Hanlon 22-Dec-08 3:35  Yes.

Mika Larramo21-Dec-08 13:44 Mika Larramo 21-Dec-08 13:44  Hi there, I plan to create a menu interface program for CD/DVD that uses classes from .NET Framework 2.0. There are some powerful classes in .NET that I want to use instead of creating them by myself to reduce the developing time. This menu program should be started automatically when the user inserts the CD/DVD in the drive. This is done by using the AutoRun technology in Windows. The problem is that if .NET Framework 2.0 is not installed in the computer this program can not be started. Then the user must first install .NET Framework 2.0 before the program can be run. Well, this is a common problem to all .NET programs and normally maybe this is not a big problem, but this program is supposed to show a menu interface immediately, and, I guess most users expect that, always... I know that Windows Vista always have .NET Framework 2.0 installed and I guess most Windows XP users today also have it. But I have never found any statistics about this. Does anybody know an Internet site that have statistics about how many people that uses .NET Framework 2.0, and the other versions of .NET Framework? Does Microsoft have some statistics? /Mika Re: How many people have NET Framework 2.0 (or later) installed? Christian Graus21-Dec-08 16:25 Christian Graus 21-Dec-08 16:25  I would still say that you'd be crazy to assume everyone has .NET. Just write a bootstrapper that installs it from your CD. Christian Graus Driven to the arms of OSX by Vista. Re: How many people have NET Framework 2.0 (or later) installed? Mika Larramo3-Jan-09 15:42 Mika Larramo 3-Jan-09 15:42  Yes. I will of course check if NET Framework is installed, as the first thing I do, and start an installation if not. But I am just worried it will take a very long time. NET Framework is big and people expects a menu appear immediately. But I have to do some tests and see how long time it will take. And see how the user experience is if they need to wait long time before the menu appears. Re: How many people have NET Framework 2.0 (or later) installed? Thomas Stockwell22-Dec-08 6:20 Thomas Stockwell 22-Dec-08 6:20  The only thing that can really be assumed: All Windows Vista and above OS will have at least .NET 3.0. Unfortunately, Microsoft has not pushed .NET 2.0 or .NET 3.0 to older systems through either Windows Updates or Service Packs. Regards, Thomas Stockwell Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning. Visit my Blog Re: How many people have NET Framework 2.0 (or later) installed? Mika Larramo3-Jan-09 15:47 Mika Larramo 3-Jan-09 15:47  It would be interesting to know how many percent of for example the Windows XP users really have NET 2.0 installed, but there are maybe no official statistics here to read. But I guess the number of people having NET 2.0 or above is increasing very fast, because more and more program uses it and installs it. And in Vista it is always included (as part of 3.0).
