  • .NET Framework 4.0 mysteriously loses track of System.EnterpriseServices

    - by Lorin Thwaits
    The GAC in .NET 4.0 is cut into two parts now -- one half for .NET Framework 2.0 stuff, and the other for v4.0 stuff. When compiling any project, targeting .NET 2.0, 3.5, or what have you, this annoying error may pop up: Could not load file or assembly 'System.EnterpriseServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. In that case, open a run box and perform this copy command: xcopy %ProgramFiles%\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.EnterpriseServices.dll %windir%\Microsoft.NET\assembly\GAC_32\System.EnterpriseServices\v4.0_4.0.0.0__b03f5f7f11d50a3a /e This reconstructs the proper portion of the GAC for that one missing file.

  • Linux C++: how to profile time wasted due to cache misses?

    - by anon
    I know that I can use gprof to benchmark my code. However, I have this problem -- I have a smart pointer that has an extra level of indirection (think of it as a proxy object). As a result, I have this extra layer that effects pretty much all functions, and screws with caching. Is there a way to measure the time my CPU wastes due to cache misses? Thanks!

  • do I have both sql 05 and 08 installed?

    - by Blankman
    When in 'sql server configuration manager' I see, under 'sql server services', 2 items that look like sql server's: sql server (sqlexpress) sql server (mssqlserver) Does that mean I have 2 versions installed at the same time? The 'sql server (mssqlserver) is currently stopped).

  • Changing an extention method from linq-to-sql to entity framework

    - by Jova
    I'm changing my project from working with Linq-to-SQL to working with Entity Framework. I have some extention methods that extend the classes created by LINQ and I'm wondering how to change them to work with the entities instead Here's an example. public static int GetPublishedArticlesCount(this Table<Article> source) { return GetPublishedArticles(source.Context as DataContext, null).Count(); } This method gets the number of published articles. Instead of using this Table<Article>, what should I use instead?

  • Preparing layout of web-design

  • ASCIIMath and TiddlyWiki

    - by Space_C0wb0y
    I use TiddlyWiki for work-notes. I already have pretty large wiki, but now I want to add math-support. As far as I understand what is written here, all I would have to do to use ASCIIMathML in my wiki would be including the script ASCIIMathML.js. Doesn't work (no effect at all). Then I found this plugin for TiddlyWiki, but when I import it to my wiki, it gives me an error in one of the regexp strings. When I download that wiki directly, ASCIIMath does not work anymore, even though I have the script in the same directory. Does anyone have a solution available, how I can add ASCIIMath to my existing TiddlyWiki?

  • PHP debugging or performance Hook

    - by Joshua
    In an interpreted language like PHP it is possible in theory to set up some sort of callback function that would be run indiscriminately after every line of code. I am wondering if such a thing exists in PHP or if such a thing could be accomplished in any way? Such a feature could be useful for diagnostics or performance tests. Does anyone know of such a mechanism in PHP?

  • How to optimize simple linked server select query?

    - by tomaszs
    Hello, I have a table called Table with columns: ID (int, primary key, clustered, unique index) TEXT (varchar 15) on a MSSQL linked server called LS. Linked server is on the same server computer. And: When I call: SELECT ID, TEXT FROM OPENQUERY(LS, 'SELECT ID, TEXT FROM Table') It takes 400 ms. When I call: SELECT ID, TEXT FROM LS.dbo.Table It takes 200 ms And when I call the query directly while being at LS server: SELECT ID, TEXT FROM dbo.Table It takes 100 ms. In many places i've read that OPENQUERY is faster, but in this simple case it does not seem to work. What can I do to make this query faster when I call it from another server, not LS directly?

  • Calculate initial velocity to move a set distance with inertia

    - by Bodyscanner
    Hello, I want to move something a set distance. However in my system there is inertia/drag/negative accelaration. I'm using a formula like this for it: velocity = oldVelocity + ((velocity - oldVelocity * inertia) where inertia is a fractional value like 0.25 So to move the item a set distance, I need to calculate what the initial velocity should be (I know what all the other values are). I've been looking at Equations of motion (http://en.wikipedia.org/wiki/Equations_of_motion) but can't work out what the correct one for my problem is... Any ideas? Thanks!

  • Should I create a new window or modify the old one?

    - by Roman
    I am programming a GUI application in Java. I do it for the first time. I would like to have a form (with radio buttons and so on). After the form is filled in and the "Submit" button is pressed I would like to have a new window. I see two potential ways to do it: Close the "old" window and open a "new" one. Remove "old" elements from the existing window and put there "new" elements. What is the standard way to go? If it is the first way, what is the command to close the window? If it is the second one, how can I remove elements from the existing window?

  • Is it good or bad practice to use var everywhere? [closed]

    - by Earlz
    Possible Duplicate: Use of var keyword in C# Hello, I've recently been discovering the awesomeness that is the var keyword in C#. Well, I didn't think about it before but I just wrote lines of code that are along the lines of var con=CreateNewConnection(); Where this would usually be IdbConnection con=CreateNewConnection(); Is this a good use of var? Is it possible to use var too often? Are there any downsides to using it? Also, one more point of consideration: We are not worried about backwards compatability. We just care that it runs on .NET 3.5

  • Wireless Network Disappearing From Available Networks (Windows 7)

    - by PeteDaMeat
    I have been using Windows 7 with a BT Voyager wireless adapter to connect to my home wireless network for around the last 6 months or so and until recently have experienced no problems. However, over the last couple of days Windows has been unable to connect to the network and the network name is no longer visible in the list of available wireless networks. The only way I have got round the problem is to reboot the NetGear router and to change the SSID to a network name which has not already been used. I do not believe the problem is with the router as my mobile phone can connect to it without any problems. The BT Voyager wireless adapter detects all other available networks so I presume this is a Windows 7 issue as it seems to occur when the PC is rebooted. This problen has happened twice in the last 2 days and is becoming extremely annoying. Does anyone have any suggestions?

  • Any significance to Google's "expires" date being Fri, 01 Jan 1990 00:00:00 GMT?

    - by Robusto
    I was looking at the response headers for my GMail account and noticed that the date Fri, 01 Jan 1990 00:00:00 GMT shows up as the value for "Expires" over and over again. I suppose this is just an easy constant to make sure the browser understands this is past its freshness date. But is there any significance to that particular date? One might as easily have used the same date in 2000, or 1970, or whatever. It's not quirky enough to be someone's birthday or date of college graduation or anything personal like that. Maybe it's just arbitrary, but I was wondering if someone has a good explanation why that particular date was chosen.

  • iPhone file corruption

    - by sfider
    Is it possible (on iPhone/iPod Touch) for a file written like this: if (FILE* file = fopen(filename, "wb")) { fwrite(buf, buf_size, 1, file); fclose(file); } to get corrupted, e.g. when app is forced to terminate? From what I know fwrite should be an atomic operation, so when I write whole file with one instruction no corruption should occure. I could not find any information on the net that would say otherwise.

  • Catching typos in scripting languages

    - by Geo
    If your scripting language of choice doesn't have something like Perl's strict mode, how are you catching typos? Are you unit testing everything? Every constructor, every method? Is this the only way to go about it?

  • Conversion of bytes into a type without changing the application (ie storing the conversion method i

    - by geoaxis
    Is there a way to store a conversion strategy (for converting some bytes) into a database and then execute it on the run time. If one were to store a complete java file, you would need to compile it, store the class and some how inject into the already running system. I am not sure how this would be possible. But using some kind of dynamic language on JVM would be nice. I see an example of execution of groovy from within spring context here http://www.devx.com/tips/Tip/42789 but this is still static in nature as application context contains the reference to the implementation and cannot be changed by database. Perhaps with JavaConfig of context it is possible. I am exploring options now, specifically with Spring 3.0. Your suggestions in any direction would be welcome.
