 - Giving IIS user credentials for authentication I think, if you enable anonymous authentication in IIS, you have to have Forms Authentication enable in your application. This you should be able to set in your web.config file. To use forms authentication you can also use Membership classes (for .NET 2.0) Tag: .NET Framework Networking and Communication Bluetooth on PC .NET Development

 - RSS 2.0 Standards Question These skipHours and skipDays sub-elements of <channel> came from scriptingNews format, designed in late 1997, and adopted by Netscape in RSS 0.91 in the spring of 1999. Per the specification as I understand it, these elements provide a hint for aggregators telling them which hours/days they can skip reading the feed channel information . In practice most RSS feed readers do not honor these elements, and to compound matters the majority of RSS feeds do not supply these elements in the wild. You can reasonably expect that many feed aggregators will read your published feed regardless of the time-to-live or skip days/hours information you provide. I would suggest that the best course of action would be to modify your feed generation logic to only publish new channel items on Monday-Friday and not add new channel items on the weekend. If you are having trouble with the feed generation, I wrote a Microsoft .NET class library framework that is available on CodePlex at http://www.codeplex.com/argotic , and in the upcoming .NET 3.5 framework Microsoft will be providing support for handling syndication. As the original RSS 2.0 specification can be somewhat hazy on details, I would like to point you to http://www.rssboard.org/rss-specification , which usually does a better job of explaining the specification elements.

 - UDP Socket listening, how to listen more than 1 socket at same port? Hello, I have 2 instances of server. Both instances create UDP socket listening for incoming messages. It seems that only 1 instace of my server can listen to the messages, the other seems to see that the UDP socket is not available when it suppose to receive. Below are portion of my code: Socket udpSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); udpSocket.SetSocketOption(SocketOptionLevel.Socket,SocketOptionName.ReceiveBuffer,BufferCapacity); udpSocket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, 1); int servicePort = (int)transport.Properties["port"]; System.Net.IPEndPoint localEndPoint = new System.Net.IPEndPoint(System.Net.IPAddress.Any, servicePort); IPEndPoint sender = new IPEndPoint(IPAddress.Any, 0); EndPoint tempRemoteEndPoint = (EndPoint)sender; udpSocket.Bind(localEndPoint); while (keepAlive) { fetchSignal.WaitOne(); //This call is made to yield processor resources, Remote Client doesn't //consume 100% of the CPU. Thread.Sleep(1); while (keepFetching && (udpSocket.Available > 0)) //only if data is available.. { ....... } } NOTE: The 2nd instance see that the udpSocket.Available is 0. While the 1st instance can see that the udpSocket is greater than 0. Thanks a lot for any help, N1C0 Tag: .NET Framework Networking and Communication Bluetooth on PC .NET Development

 - Peer.IsOnline has always property set to false Hello, folks, I can't understand one important thing. I'm playing with ContactManager. In my sample, I've got a set of contacts, but I can't determine if they are online or offline. I mean that the property of each PeerContact I work with is always false, not true. I do the following: Code Snippet public class PeerContactSearcher : List , IPeerContactSearcher where T: PeerContact { //... foreach ( PeerNearMe peerNearMe in PeerCollaboration .GetPeersNearMe()) { try { contact = (T)peerNearMe.AddToContactManager(); this .Add(contact); } catch { // Contact was already saved in Windows Contacts } } // Looping for peer contacts saved in Windows Contacts foreach ( PeerContact peerContact in PeerCollaboration .ContactManager.GetContacts()) { if (peerContact. this .Add((T)peerContact); } } And I can't do this: Code Snippet contact = (T)peerNearMe.AddToContactManager(); if (contact.IsOnline) this .Add(contact); because here no contact will be added. What should I do to get Contact presence information I wonder Also how can I set local contact presence and get presence of remote peer contact Tag: .NET Framework Networking and Communication Bluetooth on PC .NET Development

 - Extra space on right side and bottom of a DataGridView Greetings, I'm trying to display the status of a set of "resource managers" (imagine a set of heaps). Each column of my display is a different manager, and the 'rows' are different sizes in each column, and represent the "allocated" or "free" status of that region in the manager. the following demo program shows my problem: I can't seem to get just one column in a DGV: the layout always includes some extra space at the right and bottom. I've made this area RED. I'm convinced its part of the DGV., and not part of the table or panel forms. I believe I need the DGV's to AutoSize, so that the columns of the table are full length. This allows the outer panel to do the scrolling of all columns in parallel. I have tried to clip the DGV to the bounding rectangle of the column, but I've not been able to coax the appropriate size from the column. In summary, I need some Visine to get the red out.

 - Invalid character in the given encoding For this file you can replace all occurrences of the �� character with ". BTW, for the �� character there is a matching left quote �� , which is equally unsuitable as an XML attribute value delimiter. Used together the pair looks like this: ��1981��, which is different from "1981". Have you created the file with Word If yes, then probably it was not a good idea. Use specialized XML editor such as : 1. Visual Studio built-in XML editor 2. Xml Notepad 2007. That's a free download: http://www.microsoft.com/downloads/details.aspx familyid=72d6aa49-787d-4118-ba5f-4f30fe913628&displaylang=en 3. search the Internet for other XML editors For quick edits a simple plain text editor like Notepad that doesn't do any automatic character substitutions in order to improve typographic appearance of the text can also be OK. With regard to encodings, UTF-8 is used most often, that's one of standard XML encodings, and, as a rule of thumb, I'd recommend the use of UTF-8 unless you have a specific reason not to do so. Encoding name can be specified in Xml declaration: < xml version="1.0" encoding="UTF-8" > The corrected file: < xml version="1.0" >  <bookstore> <book genre="autobiography" publicationdate="1981" ISBN="1-861003-11-0"> <title>The Autobiography of Benjamin Franklin</title> <author> <first-name>Benjamin</first-name> <last-name>Franklin</last-name> </author> <price>8.99</price> </book> <book genre="novel" publicationdate="1967" ISBN="0-201-63361-2"> <title>The Confidence Man</title> <author> <first-name>Herman</first-name> <last-name>Melville</last-name> </author> <price>11.99</price> </book> <book genre="philosophy" publicationdate="1991" ISBN="1-861001-57-6"> <title>The Gorgias</title> <author> <name>Plato</name> </author> <price>9.99</price> </book> </bookstore> Tag: .NET Framework Networking and Communication Bluetooth on PC .NET Development

 - Versioning problem with strongly named asemblies Interesting problem you have there. Strongly named assemblies are immutable and provide a unique ID but depending on how your licensing engine works you don't necessarily need SN assemblies just to get a unique ID. The GUID associated with an assembly is effectively unique as well. However nothing prevents someone from creating a new assembly with the same ID. But is this a big deal since all they'd be doing is creating a new assembly that now is "effectively" licensed. They still wouldn't be circumventing your licensing I believe. Again, it depends on how licensing works. You seem to be tying licensing to versioning through SN assemblies. I'm not sure this is going to be worth the effort. Have you looked into the licensing model provided by .NET. It is generally associated with components and controls but technically it can be used anywhere. I haven't done anything with it myself so I won't be much help but I'll throw out a theoretical solution anyway. You would create a custom licensing provider that handles your specific needs. You would ship a LIC file to each customer. The LIC file would determine what reports (and perhaps what versions of what reports) the user could use. When the Launcher loads a report it uses the licensing subsystem to verify the user can use the given report. In your custom code you would validate against a report id and/or the version. For example you might have a subscription license that allows a user to use all versions of a report whereas the cheap license allows for only a specific version (and maybe any updates). This effectively locks out the Reports assemblies from general use without a license. I don't know that you need the Launcher or the Middleware to be secure since they are useless without the reports. If you have custom code that you don't want exposed then use an obfuscator or nShroud to encrypt the code to protect it. Someone else might be able to provide more insight into how the licensing model in .NET works. You can also look online at MSDN. Nevertheless it breaks the versioning/licensing issue you have while still allowing you to do licensing.

 - CLR naming conflicts I already understand overloading. In my case I had a function in a base class with name, let's say, XXX. In a derived class I created a property with name XXX. In C++ the same name in a derived class hides the name in the base class in the scope of the derived class, and is perfectly legal. If it is not perfectly legal in CLR, the compiler should give an error message when compiling the implementation of my derived class. But the compiler did not. The gist of my question was to understand the rules of name clashes for identifiers. I still so no good documentation which explains these rules. I assume identifiers having the same name in a class is illegal, but I aslo assume scope is involved in what is legal or not. In a class hierarchy, identifiers for each class in the hierarchy are in different scopes. So I do not think the rules are as simple as a blanket statement that identifiers in the same scope are illegal except for overloaded functions, simply because I have to understand how those rules apply to class inheritance, where my example takes place.

 - Reverting to appDomain user after remoted users flowed identity is checked. The following code reads the user Identity flowed over TCP to the server where I check for membership. With a minor inconvenience this works fine. The problem I was concerned about is if the thread is now identified as having the remote user's identity then the server may not have all the authority it needs to do things like log errors. We don't want to give each user the authority so we woud like to revert to the Identity of the user/account that launched the server. Unlike impersonating a user, the flowing the user via remoting doesn't appear to have a WindowsImpersonationContext that we can simply call Undo(). Fortunately I discovered that the appDomain identity is still available and using the following code I think I was able to revert to the app Domain principal. Is there a more straight forward way to accomplish this Are there any pitfalls to using this approach //Get the Identity "flowed" by remoting. (the identity assigned to the thread.) IPrincipal principal = Thread .CurrentPrincipal; WindowsIdentity identity = principal.Identity as WindowsIdentity ; //Get the appDomain Identity & create a principal from it. WindowsIdentity appDomainIdentity = WindowsIdentity .GetCurrent(); WindowsPrincipal appDomainPrincipal = new WindowsPrincipal (appDomainIdentity); //Determin if calling user has appropriate role. Minor inconvenience IsInRole didn't work. bool isXBAdmin = principal.IsInRole( @"XBDEV33\XBAdmin" ); bool isXBAdminManual = false ; foreach ( IdentityReference identRef in identity.Groups) { IdentityReference account = identRef.Translate( typeof ( NTAccount )); if (account.Value == @"XBDEV33\XBAdmin" ) { isXBAdminManual = true ; } } //Revert the thread to the appDomain principle.

 - SQL Update Sure no worries. OK so you are using ODBC. It will indeed take some time in that case, as with any other approach except if you are using some other "helper" classes, such as using SQL classes or adding references to other SQL assemblies which expose some cool stuff. I don't think the ODBC has such features I'm afraid. Is this an MS Access database you are inserting data into Or SQL Server Generally MS Access will be slow if you are inserting a large number of records (since it really was designed for "home" based users and can't handle huge amounts particularly well. That is why there is SQL Server as an alternative) If I find anything, I will be sure to post but I'm sure someone else will also chip in, which of course is welcomed as always.

Grooovie

After surfing the web for 3 days fulltime I only find bluetooth samples for Mobile applications.

I noticed that finding "Bluetooth Stack" gets me to more PC based BT info, but nowhere I can't find what i need:

I want to talk Bluetooth between PC and Mobile, the Mobile part will be probally MIDP cause it's a bigger spectrum of users.

Say I just want a chat program between PC -> Mobile with BT without annoying security questions.

I got a cellphone with BT, I got a PC with a USB BT stick and Toshiba Bluetooth Stack on it. What should I do

I think 'manufacturer' Bluetooth Stack is the driver package for running BT on your device, cellphone or PC.

I only found a .NET non mobile libaray called BlueTools, but I dont know if this is usefull aka without security questions.

Please help me!

Thank u

Well there's 32feet.NET which provides Bluetooth (and IrDA and OBEX) support for .NET applications on both desktop and CE Windows. It currently only supports the Microsoft stack on both platforms. You can probably remove the Toshiba stack and use the Microsoft-supplied one in XP SP2 if you want to use the library. (I work on the library BTW).

I don't know what "security" problems you refer to...
