    - pdb files for assemblies in GAC? Hi... I didn't see any pdb files actually in the gac directory hierarchy. Is there anything wrong with putting the pdb files in the gac directory? Thanks Mark Tag: Application Physical Path Tag: 136774

    - Winsock error 10004 on UDP Socket ReceiveFrom This is a multi-part message in MIME format. ------=_NextPart_000_000E_01C85E74.051F3E10 Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=original Content-Transfer-Encoding: 7bit Hi, (.NET Framework 2.0 on Windows 2003 SP1) I'm getting lots of 10004 WSAEINTR errors when I try to do some UDP communication. From a packet capture I learned that my application is responding with an ICMP Port Unreachable after the remote responds to my query. Example: Me -> Remote: UDP request (valid request) Remote -> Me: UDP response (valid response) Me -> Remote: ICMP Port Unreachable (with a copy of the response attached to the ICMP message) Port numbers do match, so do my payload sequencenumbers. My basicly code looks like this (removed irrelevant code): socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReceiveTimeout, timeout); bytesSend = socket.SendTo(buf, remoteEp); bytesReceived = socket.ReceiveFrom(inData, inData.Length, SocketFlags.None, ref sendingHost); socket.Close(); I get the 10004 error once every 50 requests (could be more or lesss), all other requests succeed without errors. Can someone give me some more insight in why I am getting the WinSock 10004 errors? I've attached the class which is causing the problems. The method in question is called ExecRequest().

    - This should be easy as pie: convert local to UTC and back I'm looking for the best way to convert a date/time to UTC and back to Local. This has to be built in the Framework, but eberything I try gives me something other than what I expect! I was tempted to do get the current offset from GMT and use that IN ALL CASES to convert to and fro, but this offset isn't always the same across seasons, due to daylights savings, etc. Here's my sorry excuse for TZ conversion functions. Can someone give me a better way?

    - What is the actual runtime version of .NET 3.5 framework? Hi all, I am using release version of VS 2008 in projects targeting .NET 3.5, however I just noticed that System.Runtime.InteropServices.RuntimeEnvironment.GetSystemVersion() returns old "2.0.50727" - indicating that the code runs under .NET 2.0. .NET 3.5 installed just fine - I resorted to creation of brand new console project targeting .NET 3.5, it uses System.Linq, and compiles and runs just fine, the test code I use is as follows: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Console.WriteLine(".NET runtime version: {0}", System.Runtime.InteropServices.RuntimeEnvironment.GetSystemVersion()); Console.ReadLine(); } } } There are no dependences on any old code in this example. What's going on?!?! Can someone in the know confirm that this is supposed to be the expected behavior (if so it is really really odd). regards, Alex Tag: Application Physical Path Tag: 136739

    - HttpListener and HTTP.sys questions Hi... Don't know if this is the best group for this, but didn't see another jump out at me as a better choice... I'm just getting my feet wet with System.Net.HttpListener (actually trying to sort out what a legacy app is doing with it). At first, the whole thing was confusing; I'm used to one process being able to own a socket on a port, so this whole multiple listeners, possibly conflicting with IIS befuddled me a little. Did some research and found the pages about HTTP.sys and the new functionality. A couple of questions (perhaps picayune) that I didn't see answered: 1) Which os process loads up http.sys and facilitates the many processes/one port functionality? 2) The MSDN page for System.Net.HttpListener says that it needs Xp sp2 or 2003 to use - *but* Xp comes with IIS 5.1, not 6.0. The other pages I found said that IIS 5.1 was built with winsock and is still bound to the 1-port/1-process model, while IIS 6+ was re-coded around the new HTTP.sys functionality. So when the System.Net.HttpListener docs say Xp sp2 at a minimum, I'm inferring that that means "and either you use different ports or turn off IIS 5.1". Correct?

    - Where to start? Hi all, I've been dabbling with various aspects of the new 3.5 technologies and I can tell there's loads of potential for creating powerful new applications, but I'm finding it tough to know where and how to start. I've been coding on .NET since it was in its alpha incarnation way back in 2000, but this latest version is a bit daunting. There are so many new technologies to learn and many of them seem to have fairly steep learning curves. Has anyone else found the same thing? I want to release new versions of several applications ranging from a simple desktop end-user app to an n-tier corporate app, and the promises of some of these new technologies are very tempting. I'd love to use XAML for the front end, skin the apps, introduce some simple animations to make the GUI more intuitive etc. One of my n-tier suites would benefit from peer-to-peer chat so I'm thinking WCF might be good for that. Printing has always been a point of contention but it seems that WPF documents could change all of that. I have no idea if WF could be of benefit to any of my apps, because I simply don't know enough about what it's for! The problem is, where to start? I've found plenty of "hello world" samples for XAML and examples illustrating some of its concepts, but the few tutorials I've found seem a bit lacking. XPS documentation is abysmal, and I haven't even scratched the surface of WCF --- of course, this ignores things like WF, CardSpace, SilverLight, XBAP etc etc. I can't even seem to see many dedicated newsgroups on the MS server for things like WPF, which I find quite amazing. Maybe I'm not looking in the right place? At the moment I feel that if I were to just dive in and start coding, I'd look at my work a few months later and wish I'd done most of it differently, or would find so many better and easier ways to achieve what I'd just done that would have cut my production time in half. For instance, when printing with WPF should I just go right ahead and start coding the document structure or could I use a tool like Expression to create some sort of document template visually (and no doubt a lot more easily)? What I'd love to find is a proper, MS (or MS endorsed) soup-to-nuts application that covers all or most of the above technologies and uses them with best practices in mind for a real world scenario, complete with source code and some decent documentation. Something like "NorthWind for 2008". Does anyone know of anything that fits the bill? Thanks, Alex Tag: Application Physical Path Tag: 136729

    - multiple SpeechRecognition Modules and different languages under .NET3.0 Hi Newsgroup, I'm trying to use class "SpeechRecognitionEngine" under .NET 3.0. My intention is, to recognize multiple grammers in different languages, thus I've done the following: .... do some initalization with the grammer objects.... - SpeechRecognitionEngine.LoadGrammer(oGermanGrammer) - SpeechRecognitionEngine.LoadGrammer(oEnglishGrammer) .... the "Grammer" is build by GrammerBuilder, with a given "Culture". e.g.. grammarBuilder.Culture = new CultureInfo("en-US"); When loading the "english grammer" an exception is thrown by the framework with the hint, that the actual Speechrecognition module does not match the loaded grammer. sfsg. under "Control Panel"->"Speech Properties" only the German Modul is installed.

    - Frustrated trying to position controls in a xaml window. I'm trying to position controls in a window and am having a very difficult time. I want all the controls to be anchored top/left so when I do the final resizing of the window, all the controls sit in the same position. However, as I place controls toward the right side of the form, the left alignment changes to right, and the margin changes from ##,##,0,0 ##,##,##,0 to 0,##,##,0. so to position the control just as I want, I have to painfully edit he margin values. In some cases, when the control is on the right side of the form and the control has the value of ##,##,0,0, the left margin is not what I would expect and the control repositions its self in a place that doesn't make sense. Also the widths keep changing on me. This is a royal pain. What am I doing wrong? Thanks. -- moondaddy@newsgroup.nospam Tag: Application Physical Path Tag: 136706

    - Interprocess Communication: I need a mix of Remoting and Webservice The problem: I'm writting some software to manage a building. All the devices (mostly doors and cameras) run a light version of Linux, with mono inside And we've got bigger Linux server (with mono inside). The server need to talk to individual devices (door/camera). Ideally I like to use remoting and have my device application listening to one port.

    - Managing errors while loading App.config I am using 'Settings' (the auto-generated Properties.Settings) and ConfigurationSection derived classes in my application. If my configuration file (app.config) gets corrupted (or the user changes it incorrectly) then I would like my application to pick up settings defaults and not to keep trying to load from the config file, and hence create an exception, each time. Both the auto-generated Properties.Settings and ConfigurationSection derived classes have defaults. What I'm currently getting is an exception every time I reference one of these settings if the config file is corrupted. If the config file is corrupted I would like to somehow set the ConfigurationManager to an empty or null app.config file so that all subsequent configuration settings calls will return defaults and won't keep generating exceptions each time. The application runs fine on defaults and is much better to do this than to just terminate. Does anyone know if this is possible? Tag: Application Physical Path Tag: 136672

    - throttling iocp threads in async server Hello, I'm designing an async socket server and I've read that the IOCP thread pool can overwhelm the System.ThreadPool. I'm thinking about throttling the IOCP threads by only allowing up to MAX connections to be accepted at any given time where MAX is less than the number of threads in the System.ThreadPool. So, for example, if the current number of accepted sockets is N (where N < MAX), accepting a new connection increments N and closing an accepted socket decrements N. If N == MAX, then no more new connections will be accepted until N is decremented. While N == MAX, newly established TCP connections simply queue up in the kernel waiting to be accepted. Does this sound reasonable? Thanks for any help, Marc Tag: Application Physical Path Tag: 136604

    - Best way to store a connection string machine wide. I have several applications running on a workstation all pointing to the same sql server. I would like a way to save the connectionstring once on the machine and have all my applications be able to read it. In the event of a problem where we have to change servers, I would like to be able to update the connection string in this one place and proceed. I have examined shared assemblies, and I have thought of storing the connection string in machine.config. I have been to successful with either of these methods. In VB6, is used a dll and it worked fine. What is the preferred way of doing this. -- Thanks Arnie Tag: Application Physical Path Tag: 136573

    - Napster installer issue I have Windows XP and I am trying to download the napster installer. Everything works up until configuring the napster burn engine. I get a registry error box there was a problem running the napster installer. Download and try again. I get this over and over. Napster support after many trys says something wrong with my computer. Any suggestions? Should I delete everything to do with Napster in the registry and try again? Thanks. Tag: Application Physical Path Tag: 136572

    - Invalid value for key AttachDBFileName - related to 16-bit calling code ? This thing is complicated so bare with me. We have a pure .NET application using an SQL express database which we deploy via ClickOnce. When we launch the application via the normal shorcuts (internet or program files) it *always* works. Now the beauty is that this application has to be launched from a ***16 bit Delphi 1 application*** (nobody chooses this, neither did we - the 16bit app will live for at least 2 years - and this application is still used by tens of thousands of customers). This delphi application has a plugin mechanisms which enabled us to load 16-bit "add-ins". The short shory is the 16 bit application uses WinExec (exePath,SW_NORMAL) to launch our app. (we have control over the parameters but not over the WinExec part - the first parameter should be an EXE as well) Since the 16-bit app can't call an appref-ms (we launch the appref-ms file in program files\ourCompany\ourproduct as created by ClickOnce and documented in http://safari.oreilly.com/0321197690 ) file directly and since the clickonce application doesn't take program parameters, we have created a man in the middle .NET application (MyBoot.EXE) to do the work for us. It takes the commandline parameters from the delphi app and puts them in a local file for the .NET ClickOnce app. Now listen : - on windows vista it always works - on windows XP it sometimes works (but most of the time it does not) - if I manually launch myBoot.EXE with the commandline parameters then it always works. The question : - is there something different with Windows on Windows for 16 bit applications between XP and Vista or is my Vista machine just faster than all of the XP machines (3) on which I tested this ? - how can I overcome this problem ? (already tried increasing the timeout for the connection string but it doesn't have anything to do with that - is it the switch between 16bit code and 32 bit code? - I've also tried launching the .application file but that doesn't help me either - I've also made the man in the middle a windows application with an application.Doevents to take care of the warnings for WinExec) Thanks for any help, Van den Driessche Willy.

Can anyone tell me how to get the physical path where an application
lives? What I mean by an application is either a Windows Service or a
Winforms application. I know in asp.net Server.MapPath is what's used.
I need some type of equivelent for a non asp.net application.

The reason I need this is that I'm trying to write a file to a folder
on a server that I don't have access to. The only access I have is a
mapped drive to the machine where my Windows Service is going to be
installed. What I would like to do is get the physical path to a
directory which is actually a sub-directory of a web site on this
machine. If that is too diffecult to do then the physical path which
the Windows Service dll resides would also work as a secondary option.

Thanks.

Hello,

I'm not exactly sure if I got your question right, but if you want to know
the name of the executing process on a WinForms application, you could use
the System.Environment.CommandLine property. This is often the easiest way,
and should work on Windows Service applications, too.

Then, you had a question accessing server paths. If you have a mapped
network drive, then you could just copy your application there. But if you
are indeed talking of Windows service applications (.exe based), then simply
copying won't work, as the service has to be registered on the server
computer. For this to succeed, you will need proper rights to the server.

Hope this helps.

The path to an application depends on how it was installed. An installer
program puts it one place and a click-once install puts it another that
would not be very useful for what you want to do.
