  • Add a build number to TFS 2010

    - by Vaccano
    I have a lot of legacy Delphi 5 & 6 Code. We want to test this code using the new Microsoft Test Manager (part of VS2010) To effectively track your testing using this tool you need to use build numbers. To get Delphi 5 or 6 building in TFS Build 2010 is a huge task. One that I am not sure I want to take on. Is there a way I can just insert my build numbers in to tfs?

  • How to cheat on flash games using Cheat Engine

    - by Phenom
    There's a certain flash game I'm trying to hack. However one problem I've encountered is that I'll seem to track down a value using Cheat Engine, but then the program changes the locations where it stores the value. How do flash programs do this? I know its still possible to get around this, because I've seen someone do it before, but how is it done?

  • Scared of Calculus - Required to pass Differential Calculus as part of my Computer science major

    - by ke3pup
    Hi guys I'm finishing my Computer science degree in university but my fear of maths (lack of background knowledge) made me to leave all my maths units til' the very end which is now. i either take them on and pass or have to give up. I've passed all my programming units easily but knowing my poor maths skills won't do i've been staying clear of the maths units. I have to pass Differential Calculus and Linear Algebra first. With a help of book named "Linear Algebra: A Modern Introduction" i'm finding myself on track and i think i can pass the Linear Algebra unit. But with differential calculus i can't find a book to help me. They're either too advanced or just too simple for what i have to learn. The things i'm required to know for this units are: Set notation, the real number line, Complex numbers in cartesian form. Complex plane, modulus. Complex numbers in polar form. De Moivre’s Theorem. Complex powers and nth roots. Definition of ei? and ez for z complex. Applications to trigonometry. Revision of domain and range of a function Working in R3. Curves and surfaces. Functions of 2 variables. Level curves.Partial derivatives and tangent planes. The derivative as a difference quotient. Geometric significance of the derivative. Discussion of limit. Higher order partial derivatives. Limits of f(x,y). Continuity. Maxima and minima of f(x,y). The chain rule. Implicit differentiation. Directional derivatives and the gradient. Limit laws, l’Hoˆpital’s rule, composition law. Definition of sinh and cosh and their inverses. Taylor polynomials. The remainder term. Taylor series. Is there a book to help me get on track with the above? Being a student i can't buy too many books hence why i'm looking for a book that covers topics I need to know. The University library has a fairly limited collection which i took as loan but didn't find useful as it was too complex.

  • redirect user, then log his visit using php and mysql

    - by Bart van Heukelom
    I have a PHP redirect page to track clicks on links. Basically it does: - get url from $_GET - connect to database - create row for url, or update with 1 hit if it exists - redirect browser to url using Location: header I was wondering if it's possible to send the redirect to the client first, so it can get on with it's job, and then log the click. Would simply switching things around work?

  • SQL Server 2005 Table Alter History

    - by Kayes
    Hi. Does SQL Server maintains any history to track table alterations like column add, delete, rename, type/ length change etc? I found many suggest to use stored procedures to do this manually. But I'm curious if SQL Server keeps such history in any system tables? Thanks.

  • Is there a way that WCF service can know which machine the call comes from?

    - by erxuan
    Hi, I have a WCF service and without changing any code on the client side, is there a way that I can know the detail information of the caller, such as the MachineName, and ApplicationName? Basically, I cannot change the client code to pass those pieces of information over. I tried to use System.Web.HttpContext on the server side to track this information, but HttpContext.Current is NULL. I guess that is not the proper usage of it. Any suggestion? Thanks Sarah

  • How can I script an alert for when my Amazon Web Service usage goes above a certain amount?

    - by frabcus
    We're using S3, SimpleDB and SQS on quite a complicated project. I'd like to be able to automatically track their usage, to be sure we don't suddenly spend large amounts of money when we didn't intend to (perhaps because of a bug). Is there a way of reading the usage figures of all Amazon Web Services and/or the current real time dollar cost of an account from a script? Or any service or script which provides alerts based on that?

  • WPF ListBox's scrollviewer customizable so that there is no Scrollbar, only RepeatButtons

    - by John
    Hi I would like to customize the scrollbars of a listbox's scrollviewer in such a way that the scrollbar only consists of a RepeatButton for scrolling up and a Repeatbutton for scrolling down. Nothing else. There should be no scrollbar (track) between the buttons. One button should be to the left of the ItemsPanel (scroll up) and the other on the right of the ItemsPanel. Is that possible?

  • Which information (files) of an eclipse-workspace should be tracked by source control

    - by Phuong Nguyen de ManCity fan
    I want to track the workspace of eclipse by source control so that important settings can be backed up. However, there are a lot of kind of *.index inside the .metadata folder of workspace. Some information are important, for example Mylyn repository, but some information is merely cached files and thus, doesn't make sense to me for being tracked. In short, what files inside eclipse workspace that should be tracked so that I can restore the working workspace after problems (like meta data file deleted, etc.)

  • Tracking upstream svn changes with git-svn and github?

    - by Joseph Turian
    How do I track upstream SVN changes using git-svn and github? I used git-svn to convert an SVN repo to git on github: $ git svn clone -s http://svn.osqa.net/svnroot/osqa/ osqa $ cd osqa $ git remote add origin [email protected]:turian/osqa.git $ git push origin master I then made a few changes in my git repo, committed, and pushed to github. Now, I am on a new machine. I want to take upstream SVN changes, merge them with my github repo, and push them to my github repo. This documentation says: "If you ever lose your local copy, just run the import again with the same settings, and you’ll get another working directory with all the necessary SVN metainfo." So I did the following. But none of the commands work as desired. How do I track upstream SVN changes using git-svn and github? What am I doing wrong? $ git svn clone -s http://svn.osqa.net/svnroot/osqa/ osqa $ cd osqa $ git remote add origin [email protected]:turian/osqa.git $ git push origin master To [email protected]:turian/osqa.git !

    - by est
    Hi everyone, recently this post inspired me, I want to track my own life, too. I take a look at my cellphone's clock every time when go to sleep or after wake up, so I need some program to hook to my cellphone's on/off button, and log the timestamp when I press it. I am using WM6.5 on a HTC TyTN II. If there is existing software that can do this with few settings and tweaks it would be nice, but I can also write code myself. Any suggestions?

  • Should a Stack have a maximum size?

    - by Sotirios Delimanolis
    I'm practicing my knowledge of ADTs by implementing some data structures, even if most already exist. With Stacks, a lot of books and other documentation I've read talk about the stack throwing an error when you try to add an element but the stack is full. In a java implementation (or any other), should I specifically keep track of a maximum stack size (from constructor), check to see if that size is reached, and throw an overflow exception if it is? Or is not such a big deal?

  • How can I trace a variable at runtime in C#?

    - by luvieere
    How can I track a variable's values as they change, at runtime, in C#? I'm interested in the same functionality that the debugger provides when I'm tracing a variable through execution steps, only that I need to call upon it from my code. Some sort of key-value observing, but for all kinds of variables(local, class, static, etc), not only properties. So, basically, receive a notification when a variable's value changes.
