I never worked with remote WMI so I never ran in this problem.
So back to the topic.
I think in your case you can abort your threads.
But I think it would be a better solution, to tell the thread (you want to abort) that it should exit immediately after it finished its query and leave it alone/let it run till its exits (maybe you should add a kind of observer to abort threads, that didn't finish in a determined timeout).
So you couldn't use your semaphore any more (because of the possibility, that more than 3 threads are running) but it would be better to let the thread make a clean exit.
Why I think this is a better solution?
WMI calls are made through some unmanaged (not sure) COM interfaces.
Now if you abort your thread, there maybe will be some resources that would be still locked and never
gets freed till the application exits.
On the other hand you could also try to do some clean up in your thread if it gets aborted.
Something like this:
public void ThreadFunc(object obj)
{
try
{
DoSomeOperation();
}
catch(ThreadAbortException ex)
{
DoAbortCleanupStuff();
}
finally
{
}
}
I hope that helps.Greetings

I've been asked to write a script that runs on certain files across a server. These files are always stored within the same location within each top level folder e.g
Server\folder1\mydoc\file
Server\folder2\mydoc\file
Server\folder3\mydoc\file
Server\folder4\mydoc\file
So I have a script that runs on 'file'
I need this script or another program to monitor 'Server' finding all 'files' in that location to process and also to find 'file' whenever a new folder eg 'folder5' is created.
Is this even possible? I have no idea how to proceed or what to start reading up on to work out how to be able to do this.
Many Thanks

You could write a windows service that monitors the folders (with a FileSystemWatcher object), and fires off a processing thread whenever a new file is copied to one of the folders..45 ACP - because shooting twice is just silly

BTW, your message got me thinking about the FileSystemWatcher, and there a few gotchas you should be aware of. Some programs may cause the Changed event to fire twice for each file they create (Notepad is one of those programs). The problem with FileSystemWatcher is that you don't know why the file changed - just that it did. So I started messing around wit code and am in the middle of a wrapper class that addresses that issue. I hope to post an article about it before the end of the weekend..45 ACP - because shooting twice is just silly

Hi All,
I have to out put the result of my INputfile.aspx file in to an Html file on a browser.
The code under my Inputfile.aspx file is as follow:
DataSet ds=new DataSet();
SqlDataAdapter sda = new SqlDataAdapter("T2S_SELECT_SENDFINAL_msg", Utilities.ConnectionString);
sda.SelectCommand.CommandType = CommandType.StoredProcedure;
sda.Fill(ds);
DataTable dt=ds.Tables[0];
GVResult.DataSource = dt;
GVResult.DataBind();
The out put is just a single column from a table.
I would like the data to be seen on Inputfile.html not on Inputfile.aspx?
Is there any way i can convert my aspx file in to Html.So that the browser shows Inputfile.html not aspx?
Many thanks

You need to setup your web server to handle aspx. Once this is setup, it will be able to understand the content of your aspx files and output html files to the browser. You don't need to worry about this conversion.

Thanks for your help much appreciated.
I have only one html file in the project.All the remaining are *.aspx files.
Can you let me know what should i do on my webserver?
Many thanks

R u there?
please dont answer like the way you have mentioned.becuase it doesnt mean anything.

Sorry I am not good at explaining things. I had configured Microsoft IIS before, to handle ASP.NET applications. I also configured Apache to achieve the same thing. However, the details on how I did this cannot be explained here because I had forgotten all of them. However, the process is not complicated. The web servers have plug-ins to handle ASP.NET. You need to specify how aspx files are handled. Please refer to Microsoft documentations for more information. Other experts here may also give you a better answer. Please wait patiently!
Good luck!

Hi;
How can i run the webcam on the my notebook in c# 2005. I read alot of paper in internet but i cant. i think need library then import my project but i cant. So there are any help somebody.
|
|
|
|
|
you can p/invoke the twain_32.dll (thats ofcourse requers that your webcam has twain compatible drivers), Or you can use WIA (see: WebCam Fast Image Capture Service using WIA[^]), the 3rd option is to use DirectX, 4th option (and probably the easiest), is to use a 3rd party .net component.

I use windows media encoder.
|
|
|
|
|
can you explain it please!
|
|
|
|
|
OK,
First you need to download the windows media encoder. I use version 9
http://www.microsoft.com/downloads/details.aspx?FamilyID=5691ba02-e496-465a-bba9-b2f1182cdf24&displaylang=en.
Once you download it and install, run it from the start menu. The dialogs are straight ahead.
You will be broadcasting a live event from your server. Pick your device from the device options menu. I use Broadcast Method = pull from...
Pick a port (I use 2009. URL for Internet = http://192.you.fil.lin:port# or choose a lan connection or both. I use multiple rates.
Once you have it working and you can see your broadcast at the server. Let me know and I can give direction on the ASP.net end of it.

Hi..........
I want to develop a C Compiler using C#3.0 So is it possible??? How should i go for this????

Take a class on writing compilers. I assume they still teach this in computer science courses....45 ACP - because shooting twice is just silly

Writing a C compiler is not a simple piece of work: it can be done in C#, and the actual lexical / parser / code generator design is well established. But what it won't let you do is run a program - to do that, you will need a library of back up stuff: Add, subtrcat, multiply, divide, write a character, etc., etc.
It's a big job, probably a couple of man-years, but if you want to try, give google a shot with "how do I write a c compiler" and you will get thousands of hits!If Barbie is so popular, why do you have to buy her friends?

Thanks for ur reply...But i m not getting what u r trying to tell me...can u please elaborate what u r trying to say?
Thank You

Writing a C compiler is not a simple piece of work.
You also need to write a large amount of background functions that the application written in C and compiled by your compiler need to work.
For example, at the most basic, you must provide a function to write a character on a screen.
Then to write a string.
Then to cope with all the parameters of the "printf" function.
And to add two ints.
And to add two floats.
and to subtract two ints.
etc.
Actually parsing the input is relatively simple, as is code generation, but I think you will have a lot to do to get a C program to run as output by your compiler.
Google can help you if you do decide to do it: try to search for "How do I write a C compiler" and it will give you a lot of information.If Barbie is so popular, why do you have to buy her friends?

I guess an easier route would actually be to create an intermediate compiler which creates IL (which is effectively what MS did).
I would imagine that converting the parsed code into machine code would be something of an arduous task but creating IL would appear to be a translation between languages - parse the input code, create a parse tree, manipulate this tree so you have a syntax tree and then perform a similar process in reverse to generate the IL.
By concentrating on a limited set of primitive types and operands you could probably get something basic up and running within a few days.Sarchasm : The gulf between the author of sarcastic wit and the person who doesn't get it.

That certainly gets rid of a lot of work. The next problem: how do you use .NET classes with an non-OOP language like C?  If Barbie is so popular, why do you have to buy her friends?

My bad - I read the question as 'I want to write a c# compiler'... My way was definitely easier!  Sarchasm : The gulf between the author of sarcastic wit and the person who doesn't get it.
