    - Posible to resume uploads? Hi I'm busy writing an upload to web site utility, in C#, for my client. It uploads zip file to a iis server with a virtual directory shared for that purpose. By using WebRequest, WebResponse and the "PUT" method i've been successfull at uploading files. Using the Stream, StreamReader and StreamWriter i also got a nice progress bar goin. It all works lovely, but is it possible to make it resume uploads like FlashGet and ReGet is doing resume downloads? As far as I understand, they using headers to empliment resume downloads. I tried using a stream of the uploaded file(that should be resumed) on the server, but cannot seek it. Can get the size of the file. So put the file pointer to end of the file, and just start appending to the file. If that was possible it would be much easier. But it does not work. It normally comes back that seek is not allowed or just times out, depending on the method I'm using. Help would be much appreciated and if this is not the right group to ask this question at, any suggestion where to go? Thank You Kindly Tag: Threading speed Tag: 90515

    - multi user display problem Hi, I'm using ASP.NET and creating a web application. In two areas of the app, I am dynamically building pages. One displays data on screen and the other builds reports. Everything works fine when a single user is using the application. When multiple users access these pages at the same time, the display fouls up. It seems all controls are being created and displayed, but not on each individual's browser. Some controls are missing on one browser, while being duplicated on another. Can anyone help with this problem? Thanks Tag: Threading speed Tag: 90514

    - Firing events on a differnet thread I've just been thinking about scenarious where firing an event causes a number of handler to execute - all of them potentially taking some time to complete. With a UI control, that could be a problem. The answer of course is to use threads - but I was wondering what the rule of thumb was here. I've steared clear form firing the event on a different thread as I could see how that could begin to be a real nightmare to debug (so handle thread creation/management by the various handers). But I thought I'd ask. Firing the event on a different thread would be a single clean place to create the new thread. Does anyone have any opinions/advice here??? Thanks everyone. === Phil : NZ Tag: Threading speed Tag: 90508

    - Find open files on shares (WMI?) Hi, I want to programmatically discover what users are connecting to the shared folders and files on my PC (WinXP and up). I want essentially the same info you get by opening the Computer Managerment console, looking at "Shared Folders" and clicking in the "Sessions" and "Open Files" folders in there. It shows domain user, the connection host name or IP address and the names of open files. I was hoping something simple like a WMI query could do this, but the WMI objects I've looked into don't support this under Windows Server 2003. I would appreciate any pointers as to how to get this info, thanks! Richard Tag: Threading speed Tag: 90504

    - Suppress JIT Debugger? I have a custom exception handler that "wraps" an entire application. Basically, all it does is make things easier on my beta testers by letting them click a button to copy all the information I want on an exception to the clipboard, from where they can paste it into an email to me. This works fine on my development machine when I'm running the app under the VS debugger. However, on my testers' machines, which don't have VS installed, they don't see my handler; they see a request asking them if they want to invoke the JIT debugger. I'd prefer that they not see this. Is there a way to suppress the Framework's request to invoke the JIT debugger when an exception occurs? - Mark Tag: Threading speed Tag: 90500

    - private field and public property naming conventions Has anyone found any naming convention guidelines for private fields and public properties in Visual Basic .NET and C#. Below is what I currently do in each of the languages. Any comments? I would like to use the same convention in C# as in Visual Basic .NET with camelCasing for private fields and PascalCasing for public properties, but since Visual Basic .NET is case insensitive, I have to use a different name for the public property and its associated private field (e.g. add "m_" for private field). Any suggestions or documentation from Microsoft. The Design Guidelines for Class Library Developers at: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpgenref/html/cpconnetframeworkdesignguidelines.asp does not provide much advice on this issue. Also is there any guidelines on when this and Me should be used to fully qualify a public or private member? // C# public class Test { private string myVariable; public string MyVariable { get { return myVariable; } set { myVariable = value; } } } ' Visual Basic .NET Public Class Test Private m_myVariable As String Public Property MyVariable() As String Get Return m_myVariable End Get Set(ByVal value As String) m_myVariable = value End Set End Property End Class Tag: Threading speed Tag: 90496

    - Ignoring certain SSL errors in WebRequest The WinHTTP object has enormous granularity in ignoring specific SSL errors. SslErrorFlag_UnknownCA = 256, SslErrorFlag_CertWrongUsage = 512, SslErrorFlag_CertCNInvalid = 4096, SslErrorFlag_CertDateInvalid = 8192, SslErrorFlag_Ignore_All = 13056 This allowed me, for example, to declare ahead of time that a nonmatching CName in the certificate should be ignored. The HttpWebRequest .NET class seems only to provide a SecureChannelFailure value to the Status of a WebException. This seems require that anticipated errors may not be preset to ignore, and more importantly, that an invalid CName error cannot be distinguished from an invalid date, unknown authority, or wrong usage certificate error. Is this true, or am I missing something? Tag: Threading speed Tag: 90484

    - Usage Value cloaking We are developing an app in .NET 2003 1.1. Our clients pay according the the number of items processed. We need to store a usage counter in the App or SQLServer, but do not want the end user to be able to change this value (and preferably not view it in raw form, only thru our "usage view" class/form). This usage counter needs to be encrypted or cloaked, remembering that it is constantly updated during processing. Any ideas? Tag: Threading speed Tag: 90472

    - Remoting: singleton well-known I am using singleton well-known remoted object. My client applictaion creates an instance of the object, and the remoting plumbing works, creating the transparrent proxy and so on... The server's method adds the received parameters to some collection, starts some threads to do work on that data, and returns. Now, if I my client app tries to call the same method on the remoted object, the client app throws a "System.Threading.ThreadStateException" exception with a message to the effect that the thread is terminated or running and cannot restart. If a separate client app tries to call the method, it's okay though. Is this behavior by design? How can I get around it, to allow multiple successive calls from the client to the server on a well-known singleton? Or can I? Maybe I have to think about using client-activated remoting instead? Any guidance appreciated. Thanks, A Tag: Threading speed Tag: 90464

    - What class parses to get Main()'s args? Hi, For some test code I am writing, I want to convert a string of characters that I would theoretically enter on the command line into the string array that is passed to my program's Main() method. For example, on the command line I may have: c:>program.exe "This is a test" Whatever calls Main() will call using an array with a single string rather than four strings, because of the 3 spaces. Anyway, what is the parser class/method that converts "This is a test" to the appropriate string args array?

Process Id = 0x26b0, Thread Id=0x2604 ... When I added logging in WinMain() function, the log was empty. This means that it crashed before reaching WinMain(). Some other users can get it to work by disabling anti-spyware software but this one just keep crashing. Any idea on how to get more information on why it crashed?

    - drag/drop file from listview to explorer without temp-file Dear Ng, after I've drop a file from the explorer window on my listview, I saved this file as a base64str, so that I can transport it in various ways. Now the file name appears in my listview and I want to drag it, so that i can drop it somewhere else (the base64str of the file is still in memory). It works fine in the following way: ------------------------------------------------- string base64Str = (string)base64Files.GetValue(0); byte[] bArr = Convert.FromBase64String(base64Str); FileStream fs = new FileStream("c://myFile.dat", FileMode.Create); fs.Write(bArr, 0, bArr.Length); fs.Close(); ArrayList al = new ArrayList(); al.Add("myFile.dat"); Array arr = al.ToArray(typeof(string)); DataObject DO = new DataObject(); DO.SetData(DataFormats.FileDrop, arr); filelist.DoDragDrop(DO, DragDropEffects.Copy); ------------------------------------------------- But what's makes me unsatisfied is, that i need to create a tempfile "c://myFile.dat". How can I avoid this? I tried sth out with the MemoryStream, but wasn't successful! And besides, I do not understand the connection between my FileStream and the DataObject. From where do they know each other? Thanks in advance, patrick Braunschweig Tag: Threading speed Tag: 90386

    - Print Dialog Hangs - SimplePad Has anyone run into the print dialog box hanging in a .Net Winforms app? I thought it was my app but the SimplePad app that Microsoft developed hangs as soon as you hit the Print button. My app does the same thing. All non-dotnet apps print fine on the machine. It is a Windows 2000 Terminal Service box. Could it be permissions problems that don't allow the dotnet framework to display the Print Dialog? Any help would be appreciated.

    - Problem with dependency conflicts We're having a problem with one of the projects that was recently added to our solution. The project, even though it doesn't seem to have a reference to the dll, generates a series of error messages when you compile it: Error: The dependency 'ClioControls, Version=1.0.1847.16599, Culture=neutral' in project 'ClioMain' cannot be copied to the run directory because it would conflict with dependency 'ClioControls, Version=1.0.1847.24066, Culture=neutral'. Error: The dependency 'ClioControls, Version=1.0.1847.24066, Culture=neutral' in project 'ClioMain' cannot be copied to the run directory because it would conflict with dependency 'ClioControls, Version=1.0.1847.16599, Culture=neutral'. Unable to write to output file 'C:\SerialsSystem\ClioMain\ClioControls\obj\Debug\ClioControls.dll': The process cannot access the file because it is being used by another process. I think I understand what's going on, in that the machine has references to two versions of the dll. What I don't understand it how to fix it. I found a reference that says you can get around it by going into release mode, but we have a lot more work to do so we need debug capabilities. We're using VS 2003, a mix of W2K and WXP clients and W2K Server, also Visual Source Safe the most recent version. Has anyone seen this and know how to resolve it? Any help or direction to relevant documentation is welcome, Thanks in advance, David Craig. Tag: Threading speed Tag: 90384

    - .exe No debugger found I developed and windows application with Visual Studio.NET on my local development machine. When I go to deploy this application on other machines the application will not execute. The following error occurs: .exe Common Language Runtime Debugging Services Application has generated an exeception that could not be handled. Process id=0xf1c (3868), Thread id=0xca0 (3232). .exe No debugger found. Registered JIT debugger is not available. cordbg.exe !a 0xf1c It appears that is application works on machines with VS.Net installed on them. However, on the deployment machine I have all the .net dll's and other files as that on the development machine. The references in the project are pointed in the right and same locations for the development and deployment machines. Has anyone else run into this issue. Any help or direction would be great!

Hi.

Is really threading in .net so slow. I'm a mfc programmer that have stared
to write code in managed c++. I have compared thread loops in mfc with .net,
and .net loops seems to be extremely slow. I just increment a value, and
while mfc is upp at 1300000incs, .net loop has reached 4054. Am I missing
something here or is this the fakt...

You need to post your code, there could be a million things wrong with
your example that skews the results.

I suspect your benchmarking methodology is flawed. Without seeing the
code, it's impossible to tell, of course.
