Hi Guys,
I'm using the validation block (4.1) + ErrorProvider and have them integrated with my WinForms app properly, however, i can't find the setting that enables re-focusing on validation fail. i.e. when validation fails you can't currently move to the next control.
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?
Regards

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.

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

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?

Yes. You were looking at the .NET 1.1 documentation. It changed post 1.1, as detailed here[^].

Missed that. Thanks, that explains it but it seems a bit odd to remove the functionality.

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

I would still say that you'd be crazy to assume everyone has .NET. Just write a bootstrapper that installs it from your CD.

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.

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.

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).

Hello all, I have some wierdness.
using the very simple code below:
EventLog el = new EventLog("Security");
foreach (EventLogEntry elr in el.Entries)
{
Trace.WriteLine(elr.Message);
}
results with the following message:
The description for Event ID '4647' in Source 'Microsoft-Windows-Security-Auditing' cannot be found. The local computer may not have the necessary registry information or message DLL files to display the message, or you may not have permission to access them. The following information is part of the event:'S-1-5-21-51003140-4199384537-3980697693-500', 'Administrator', '26L2233A1-06', '0x86377'
As far as I can tell, it's like the .net framework can't find the source dll to resolve the message. I pulled out some old C++ code that did some event log processing and ran it on the same machine and sure enough I couldn't find the message DLL.
I know that Microsoft changed the event log API in vista/2008 but I thought the new API was backwards compatible.
Backwards compatible or not, I need to be able to read the security log on vista/2008.
Any ideas?
thanks,
Gene
