• Ron Rice Dictionary<TKey, TValue> should expose a derived KeyValuePair specialization

  In C++/STL, many generic classes include nested typedef declarations to specialize nested types. Currently, in C# there is no support for typedef, so if I want to avoid repetetive typing of a certain generic type, especially a (potentially complex) specialization of Dictionary<TKey, TValue> , I'd need to create a subclass. 1 using System; 2 using System.Collections.Generic; 3 4 namespace ConsoleApplication7 5 { 6 public class StringDictionary : Dictionary < string , string > 7 { 8 public StringDictionary( params string [] stringPairs) 9 { 10 for ( int i = 0; i < stringPairs.Length; i += 2) 11 { 12 Add(stringPairs ...Show All

• douner001 How to get ICorDebug being used by Visual Studio?

  Is there any way to do this (from add-in or macro) This gives nothing. VS API doesn't expose the necessary interface. The best solution I've found is to use EnvDTE80.Debugger2.GetExpression2() to inject my code into the debuggee process. This way is a bit wicked, but it works :) Have you found another solution or still searching Grem IcorDebug is too poor for that task too. Unfortunately, ICorDebug can't enumerate all objects in the target (although it's high on our Todo list). The Profilers (like CLR Profiler, Tutorial , Download for .NET 2.0 ) are much more suited for analysis of object usage across the managed heap ...Show All

• Stoj FtpWebRequest MKD fails

  I'm trying to create an application that will automatically upload files to our Akamai content delivery network via FTP. One of the requirements is that if the local source directory contains a new directory that does not exist on the target FTP server I need to create it. Unfortuantely everything I've tried for this gives me back the dreaded unspecified 550 error. Example: say I have two uris to my ftp server, the first representing a directory that DOES exist already and the second representing a directory that DOES NOT exist on the remote server. try{ string[] uris = new string[]{"ftp://accname.upload.akamai.com/10000/existingdir", "ftp://accname.upload.akamai.com/10000/newdir"} foreach(string uri in uris){ ...Show All

  Is it possible to write an XPath expression to return the relative complement of A in B (ie the set of all elements which are members of B, but not members of A) Here is an example: From the xml file below I would like to return the set of all pet elements in the genus 'canis', which do not have elements in other genera with pets of the same name. ie snoopy is the only dog without a namesake in another genus. < xml version="1.0" encoding="utf-8" standalone="no" > <Pets> <Genus name="canis"> <Pet name="snoopy" /> <Pet name="fred" /> <Pet name="lassie" /> </Genus> <Genus name="felis"> <Pet nam ...Show All

• Hf Kok Int64

  I'm not sure where to put this question, so if this is the wrong section: feel free to simply point me in the correct direction. :) I was wondering if there were plans to include support for Int64 numbers in the .MDB/Jet system (Or should I forget it and look at other filebased DB solutions ) Have you tried using the Currency data type At this point there are no plans to take the Access Jet database engine into the 64-bit world. I have not tried to use the Currency data type. My goal was to be able to use the same table structure/dataset in my program, but have the user be able to choose between a local .MDB file or a xSQL based database. The point of this was that I didn't want 'casual ...Show All

• biggieuk Using multiple SqlConnection objects, bad for performance?

  Hello, I am planning to use three databases on the local SQL Server. DB1 will be for App1, DB2 for App2, and DB3 will hold tables, that both, App1 and App2 need to access. With applications I mean ASP.NET applications. Obviously, I need in App1 and App2 at least two SqlConnection and SqlCommand objects, one that access their respective databases, and one that will access DB3. Will this result in a worse performance (The using of two SqlConnection objects in one aspx page as example, and switching them) Should I for better performance get rid of DB3 and add the tables there to DB1 and DB2 (Thus multiplying data, but, if the performance will be much better, it will be fine with me) I would be thankful for any advices. ...Show All

• kaizen Account cannot access private key

  Hello, I'm developping a web service with WSE 3.0. I use mutualcertificate for security and authentificate. But I can only get it working when impersonating as Administrator. Otherwise I always get the error that I cannot access private key. I've use the WSE 3.0 Certificate Tool and I have given access to everyone to the private key. But I still don't get it to work. Another option was create a local user, and install the certificates under this account. Then, impersonate the asp.net to this account. This way works as long as the user is logged in the server.

• varda-elentari How to create AppDomains when assemblies reside in IsolatedStorage?

  The project entails a server that hosts the running of user code in sub AppDomains. A specific directory in a non-roaming IsolatedStorageFile contains the assemblies the user code references. For file system security reasons, it is desirable to be able to point the new sub AppDomain's base directory to a sub directory of the isolated storage file. Is there someway of doing this - without copying files to the actual FS For example, by refering to the actual ISF directly via:<SYSTEMDRIVE>\Documents and Settings\<user>\Local Settings\Application Data\<ISFName> How would the ISF's file name be determined in this case More generally, a furture requirement for the server is to allow cabinets or zip archives to be us ...Show All
