  • Merge arrow in clear case

    - by cheiav
    Hi, I have to merge all objects from a sub branch to main branch recursively. I would like to merge manually by check in the code from sub branch to main branch instead of using merge command in clear case. So after the check in into the main branch I would like to draw arrow recursively to all my objects. ic from sub branch to main branch I have used this command cleartool mkhlink -unidir Merge <sub branch path>>@@/main/<<sub branch>> <<main brach path>>@@/main/LATEST But when I dit it, it is drawing the arrow for the directory only not for all contains of the directory. Please suggest how to draw the arrow recursively from sub branch to main branch objects. Thanks in advance

  • Java: Can't implement runnable on a test case: void run() collides

    - by Zombies
    So I have a test case that I want to make into a thread. I cannot extend Thread nor can I implement runnable since TestCase already has a method void run(). The compilation error I am getting is Error(62,17): method run() in class com.util.SeleneseTestCase cannot override method run() in class junit.framework.TestCase with different return type, was class junit.framework.TestResult. What I am trying to do is to scale a Selenium testcase up to perform stress testing. I am not able to use selenium grid/pushtotest.com/amazon cloud at this time (installation issues/install time/resource issues). So this really is more of a Java language issue for me.

  • Case Sensitivity of Action Names in Struts 2

    - by IK
    Is there an easy way to make Struts 2 action names case insensitive? Currently I have the following action defined: <action name="printTest" class="MyClass" > <result name="error">/WEB-INF/jsp/error.jsp</result> <result name="input">/WEB-INF/jsp/test.jsp</result> <result name="success">/WEB-INF/jsp/test.jsp</result> </action> If the user types URL "/app/printtest.do" instead of "/app/printtest.do" this action is not executed. Other then mod_rewrite on the httpd level or something like that, the only option that I know about right now is simply adding the same exact action and changing the name to "printtest". Ideally it would be a simple config change to struts.xml

  • boost test case for function taking user input

    - by oadams
    I have a function that takes in user input via std::cin: std::getline(std::cin, in); and creates a corresponding data structure by matching it with a regular expression. The function then returns this data structure. I'm using boost.test and I want to create a unit test to check that the output data type is correct given some inputs. However I don't know how to go about it since the input isn't passed as an argument to the function. EDIT: Is there a simple way to create a boost test case that feeds the function a string via standard input?

  • C# matching two text files, case sensitive issue

    - by Mike
    What i have is two files, sourcecolumns.txt and destcolumns.txt. What i need to do is compare source to dest and if the text doesnt match write out to a new file. The code below works except i have case sensitive issues like this: CPI Cpi These say they dont match because of captial letters, any help is always thanked! string[] sourcelinestotal = File.ReadAllLines(@"C:\testdirectory\" + "sourcecolumns.txt"); string[] destlinestotal = File.ReadAllLines(@"C:\testdirectory\" + "destcolumns.txt"); foreach (string sline in sourcelinestotal) { if(destlinestotal.Contains(sline)) { } else { File.AppendAllText(@"C:\testdirectory\" + "missingcolumns.txt", sline); } }

  • Free web-based software for team collaboration/documentation

    - by Jason Antman
    Looking for some advice here, as my search has turned up to be pretty fruitless. My group (9 people - SAs, programmers, and two network guys) is looking for some sort of web tool to... ahem... "facilitate increased collaboration" (we didn't use a buzzword generator, I swear). At the moment, we have an unified ticketing system that's braindead, but is here to stay for political/logistical reasons. We've got 2 wikis ("old" and "new"), neither of which fulfill our needs, and are therefore not used very often. We're looking for a free (as in both cost and open source) web-based tool. Management side: Wants to be able to track project status, who's doing what, whether deadlines are being met, etc. Doesn't want full-fledged "project management" app, just something where we can update "yeah this was done" or "waiting for Bob to configure the widgets". TeamBox (www.teambox.com) was suggested, but it seems almost too gimmicky, and doesn't meet any of the other requirements: Non-management side: - flexible, powerful wiki for all documentation (i.e. includes good tables, easy markup, syntax highlighting, etc.) - good full text search of everything (i.e. type in a hostname and get every instance anyone ever uttered that name) - task lists or ToDo lists, hopefully about to be grouped into a number of "projects" - file uploads - RSS or Atom feeds, email alerts of updates We're open to doing some customizations (adding some features, notification/feeds, searching, SVN integration, etc.) but need something F/OSS that will run under Apache. My conundrum is that most of the choices I've found so far fall into one of these categories: project management/task tracking with poor wiki/documentation/knowledge base support wiki with no task tracking support ticketing system with everything else bolted on (we already have one that we're stuck with) code-centric application (we do little "development", mostly SA work) Any suggestions? Or, lacking that, any comments on which software would be easiest to add the lacking features to (hopefully ending up with something that actually looks good and works well)?

  • Best Practices for Handing over Legacy Code

    - by PersonalNexus
    In a couple of months a colleague will be moving on to a new project and I will be inheriting one of his projects. To prepare, I have already ordered Michael Feathers' Working Effectively with Legacy Code. But this books as well as most questions on legacy code I found so far are concerned with the case of inheriting code as-is. But in this case I actually have access to the original developer and we do have some time for an orderly hand-over. Some background on the piece of code I will be inheriting: It's functioning: There are no known bugs, but as performance requirements keep going up, some optimizations will become necessary in the not too distant future. Undocumented: There is pretty much zero documentation at the method and class level. What the code is supposed to do at a higher level, though, is well-understood, because I have been writing against its API (as a black-box) for years. Only higher-level integration tests: There are only integration tests testing proper interaction with other components via the API (again, black-box). Very low-level, optimized for speed: Because this code is central to an entire system of applications, a lot of it has been optimized several times over the years and is extremely low-level (one part has its own memory manager for certain structs/records). Concurrent and lock-free: While I am very familiar with concurrent and lock-free programming and have actually contributed a few pieces to this code, this adds another layer of complexity. Large codebase: This particular project is more than ten thousand lines of code, so there is no way I will be able to have everything explained to me. Written in Delphi: I'm just going to put this out there, although I don't believe the language to be germane to the question, as I believe this type of problem to be language-agnostic. I was wondering how the time until his departure would best be spent. Here are a couple of ideas: Get everything to build on my machine: Even though everything should be checked into source code control, who hasn't forgotten to check in a file once in a while, so this should probably be the first order of business. More tests: While I would like more class-level unit tests so that when I will be making changes, any bugs I introduce can be caught early on, the code as it is now is not testable (huge classes, long methods, too many mutual dependencies). What to document: I think for starters it would be best to focus documentation on those areas in the code that would otherwise be difficult to understand e.g. because of their low-level/highly optimized nature. I am afraid there are a couple of things in there that might look ugly and in need of refactoring/rewriting, but are actually optimizations that have been out in there for a good reason that I might miss (cf. Joel Spolsky, Things You Should Never Do, Part I) How to document: I think some class diagrams of the architecture and sequence diagrams of critical functions accompanied by some prose would be best. Who to document: I was wondering what would be better, to have him write the documentation or have him explain it to me, so I can write the documentation. I am afraid, that things that are obvious to him but not me would otherwise not be covered properly. Refactoring using pair-programming: This might not be possible to do due to time constraints, but maybe I could refactor some of his code to make it more maintainable while he was still around to provide input on why things are the way they are. Please comment on and add to this. Since there isn't enough time to do all of this, I am particularly interested in how you would prioritize.

  • Integrating Oracle Hyperion Smart View Data Queries with MS Word and Power Point

    - by Andreea Vaduva
    Untitled Document table { border: thin solid; } Most Smart View users probably appreciate that they can use just one add-in to access data from the different sources they might work with, like Oracle Essbase, Oracle Hyperion Planning, Oracle Hyperion Financial Management and others. But not all of them are aware of the options to integrate data analyses not only in Excel, but also in MS Word or Power Point. While in the past, copying and pasting single numbers or tables from a recent analysis in Excel made the pasted content a static snapshot, copying so called Data Points now creates dynamic, updateable references to the data source. It also provides additional nice features, which can make life easier and less stressful for Smart View users. So, how does this option work: after building an ad-hoc analysis with Smart View as usual in an Excel worksheet, any area including data cells/numbers from the database can be highlighted in order to copy data points - even single data cells only.   TIP It is not necessary to highlight and copy the row or column descriptions   Next from the Smart View ribbon select Copy Data Point. Then transfer to the Word or Power Point document into which the selected content should be copied. Note that in these Office programs you will find a menu item Smart View;from it select the Paste Data Point icon. The copied details from the Excel report will be pasted, but showing #NEED_REFRESH in the data cells instead of the original numbers. =After clicking the Refresh icon on the Smart View menu the data will be retrieved and displayed. (Maybe at that moment a login window pops up and you need to provide your credentials.) It works in the same way if you just copy one single number without any row or column descriptions, for example in order to incorporate it into a continuous text: Before refresh: After refresh: From now on for any subsequent updates of the data shown in your documents you only need to refresh data by clicking the Refresh button on the Smart View menu, without copying and pasting the context or content again. As you might realize, trying out this feature on your own, there won’t be any Point of View shown in the Office document. Also you have seen in the example, where only a single data cell was copied, that there aren’t any member names or row/column descriptions copied, which are usually required in an ad-hoc report in order to exactly define where data comes from or how data is queried from the source. Well, these definitions are not visible, but they are transferred to the Word or Power Point document as well. They are stored in the background for each individual data cell copied and can be made visible by double-clicking the data cell as shown in the following screen shot (but which is taken from another context).   So for each cell/number the complete connection information is stored along with the exact member/cell intersection from the database. And that’s not all: you have the chance now to exchange the members originally selected in the Point of View (POV) in the Excel report. Remember, at that time we had the following selection:   By selecting the Manage POV option from the Smart View meny in Word or Power Point…   … the following POV Manager – Queries window opens:   You can now change your selection for each dimension from the original POV by either double-clicking the dimension member in the lower right box under POV: or by selecting the Member Selector icon on the top right hand side of the window. After confirming your changes you need to refresh your document again. Be aware, that this will update all (!) numbers taken from one and the same original Excel sheet, even if they appear in different locations in your Office document, reflecting your recent changes in the POV. TIP Build your original report already in a way that dimensions you might want to change from within Word or Power Point are placed in the POV. And there is another really nice feature I wouldn’t like to miss mentioning: Using Dynamic Data Points in the way described above, you will never miss or need to search again for your original Excel sheet from which values were taken and copied as data points into an Office document. Because from even only one single data cell Smart View is able to recreate the entire original report content with just a few clicks: Select one of the numbers from within your Word or Power Point document by double-clicking.   Then select the Visualize in Excel option from the Smart View menu. Excel will open and Smart View will rebuild the entire original report, including POV settings, and retrieve all data from the most recent actual state of the database. (It might be necessary to provide your credentials before data is displayed.) However, in order to make this work, an active online connection to your databases on the server is necessary and at least read access to the retrieved data. But apart from this, your newly built Excel report is fully functional for ad-hoc analysis and can be used in the common way for drilling, pivoting and all the other known functions and features. So far about embedding Dynamic Data Points into Office documents and linking them back into Excel worksheets. You can apply this in the described way with ad-hoc analyses directly on Essbase databases or using Hyperion Planning and Hyperion Financial Management ad-hoc web forms. If you are also interested in other new features and smart enhancements in Essbase or Hyperion Planning stay tuned for coming articles or check our training courses and web presentations. You can find general information about offerings for the Essbase and Planning curriculum or other Oracle-Hyperion products here (please make sure to select your country/region at the top of this page) or in the OU Learning paths section , where Planning, Essbase and other Hyperion products can be found under the Fusion Middleware heading (again, please select the right country/region).

  • Orchestrating the Virtual Enterprise

    - by John Murphy
    During the American Industrial Revolution, the Ford Motor Company did it all. It turned raw materials into a showroom full of Model Ts. It owned a steel mill, a glass factory, and an automobile assembly line. The company was both self-sufficient and innovative and went on to become one of the largest and most profitable companies in the world. Nowadays, it's unusual for any business to follow this vertical integration model because its much harder to be best in class across such a wide a range of capabilities and services. Instead, businesses focus on their core competencies and outsource other business functions to specialized suppliers. They exchange vertical integration for collaboration. When done well, all parties benefit from this arrangement and the collaboration leads to the creation of an agile, lean and successful "virtual enterprise." Case in point: For Sun hardware, Oracle outsources most of its manufacturing and all of its logistics to third parties. These are vital activities, but ones where Oracle doesn't have a core competency, so we shift them to business partners who do. Within our enterprise, we always retain the core functions of product development, support, and most of the sales function, because that's what constitutes our core value to our customers. This is a perfect example of a virtual enterprise.  What are the implications of this? It means that we must exchange direct internal control for indirect external collaboration. This fundamentally changes the relative importance of different business processes, the boundaries of security and information sharing, and the relationship of the supply chain systems to the ERP. The challenge is that the systems required to support this virtual paradigm are still mired in "island enterprise" thinking. But help is at hand. Developments such as the Web, social networks, collaboration, and rules-based orchestration offer great potential to fundamentally re-architect supply chain systems to better support the virtual enterprise.  Supply Chain Management Systems in a Virtual Enterprise Historically enterprise software was constructed to automate the ERP - and then the supply chain systems extended the ERP. They were joined at the hip. In virtual enterprises, the supply chain system needs to be ERP agnostic, sitting above each of the ERPs that are distributed across the virtual enterprise - most of which are operating in other businesses. This is vital so that the supply chain system can manage the flow of material and the related information through the multiple enterprises. It has to have strong collaboration tools. It needs to be highly flexible. Users need to be able to see information that's coming from multiple sources and be able to react and respond to events across those sources.  Oracle Fusion Distributed Order Orchestration (DOO) is a perfect example of a supply chain system designed to operate in this virtual way. DOO embraces the idea that a company's fulfillment challenge is a distributed, multi-enterprise problem. It enables users to manage the process and the trading partners in a uniform way and deliver a consistent user experience while operating over a heterogeneous, virtual enterprise. This is a fundamental shift at the core of managing supply chains. It forces virtual enterprises to think architecturally about how best to construct their supply chain systems.  Case in point, almost everyone has ordered from Amazon.com at one time or another. Our orders are as likely to be fulfilled by third parties as they are by Amazon itself. To deliver the order promptly and efficiently, Amazon has to send it to the right fulfillment location and know the availability in that location. It needs to be able to track status of the fulfillment and deal with exceptions. As a virtual enterprise, Amazon's operations, using thousands of trading partners, requires a very different approach to fulfillment than the traditional 'take an order and ship it from your own warehouse' model. Amazon had no choice but to develop a complex, expensive and custom solution to tackle this problem as there used to be no product solution available. Now, other companies who want to follow similar models have a better off-the-shelf choice -- Oracle Distributed Order Orchestration (DOO).  Consider how another of our customers is using our distributed orchestration solution. This major airplane manufacturer has a highly complex business and interacts regularly with the U.S. Government and major airlines. It sits in the middle of an intricate supply chain and needed to improve visibility across its many different entities. Oracle Fusion DOO gives the company an orchestration mechanism so it could improve quality, speed, flexibility, and consistency without requiring an organ transplant of these highly complex legacy systems. Many retailers face the challenge of dealing with brick and mortar, Web, and reseller channels. They all need to be knitted together into a virtual enterprise experience that is consistent for their customers. When a large U.K. grocer with a strong brick and mortar retail operation added an online business, they turned to Oracle Fusion DOO to bring these entities together. Disturbing the Peace with Acquisitions Quite often a company's ERP system is disrupted when it acquires a new company. An acquisition can inject a new set of processes and systems -- or even introduce an entirely new business like Sun's hardware did at Oracle. This challenge has been a driver for some of our DOO customers. A large power management company is using Oracle Fusion DOO to provide the flexibility to rapidly integrate additional products and services into its central fulfillment operation. The Flip Side of Fulfillment Meanwhile, we haven't ignored similar challenges on the supply side of the equation. Specifically, how to manage complex supply in a flexible way when there are multiple trading parties involved? How to manage the supply to suppliers? How to manage critical components that need to merge in a tier two or tier three supply chain? By investing in supply orchestration solutions for the virtual enterprise, we plan to give users better visibility into their network of suppliers to help them drive down costs. We also think this technology and full orchestration process can be applied to the financial side of organizations. An example is transactions that flow through complex internal structures to minimize tax exposure. We can help companies manage those transactions effectively by thinking about the internal organization as a virtual enterprise and bringing the same solution set to this internal challenge.  The Clear Front Runner No other company is investing in solving the virtual enterprise supply chain issues like Oracle is. Oracle is in a unique position to become the gold standard in this market space. We have the infrastructure of Oracle technology. We already have an Oracle Fusion DOO application which embraces the best of what's required in this area. And we're absolutely committed to extending our Fusion solution to other use cases and delivering even more business value.

  • ExtJS: Combobox in EditorGridPanel not selecting the desired item (with test case)

    - by TomH
    I'm using ExtJS to create an EditorGridPanel with a combobox for an editor in a cell. The combobox in my EditorGridPanel that is not working as I'd expect it to. When the user types the first letter of an item in the drop down list, the combobox seems to ignore it and select the first item in the list. I can reproduce the error consistently and have put together a test case here: http://cluebucket.com/dev/testcase/testcase.html Load the page and reproduce the behavior by the following -- note that this is all done using the keyboard, no mouse clicks: Click 'Add Record' (A new row is added to the grid) enter text in the text field. TAB to the Priority field without selecting anything (None will remain selected) TAB out of the Priority field. (A new row is added to the grid) enter text and TAB to the Priority field TYPE v (Very High is selected) TAB out of the priority field (A new row is added to the grid) enter text and TAB to the Priority field Type v (None is selected, but Very High should have been) TAB out of the priority field Enter text and TAB to the priority field Type l ('el') (Low is selected) TAB out, enter text, TAB to priority Type l (None is selected) It appears that whenever the user attempts to select the same value that was selected in the previous row, the combobox selects None. Any ideas? The code is available at cluebucket.com/dev/testcase/js/testcase.js Thoughts/Pointers/Corrections are appreciated!! thanks tom

  • Which is a good opensource user management system?

    - by Lost_in_code
    I'm new to php/mySQL and am trying to create a website which will allow users to register. In future, there will be a paid content area where content will be shown based on the payment status. Is there a good opensource lightweight framework which takes care of the user management part? (Register, edit user info, retrieve lost password etc). I'm a flash platform developer and not aware of how to take care of stuff like session hijacking, XSS etc. Should I go ahead and learn to do all this on my own, without using any framework? I thought of using Wordpress' user management system, but not sure how easy that would be. Any suggestion would be great.

  • NHibernate Session Management Advice

    - by Hugusta
    I need some advice on NHibernate Session Management for a C# WinForms application. I am currently porting an application to use NHibernate. I am also employing a UnitOfWork pattern as described in the link below; http://nhforge.org/wikis/patternsandpractices/nhibernate-and-the-unit-of-work-pattern.aspx My question relates to Sessions. Can you only have one session running per thread at all times? I have a scenario in which a Session (UnitOfWork) may be open for a form shown by the application but the user opens another form (i.e. Tools - Options) which I would like to have its own UnitOfWork. Clearly in this instance it would make more sense to open another Session for the "Tools - Options" form and not use the currently open session for the underlying form. Can we have a Dictionary of Sessions on the one thread? Any advice on session management is appreciated.

  • Scalaz: request for use case

    - by oxbow_lakes
    This question isn't meant as flame-bait! As it might be apparent, I've been looking at Scalaz recently. I'm trying to understand why I need some of the functionality that the library provides. Here's something: import scalaz._ import Scalaz._ type NEL[A] = NonEmptyList[A] val NEL = NonEmptyList I put some println statements in my functions to see what was going on (aside: what would I have done if I was trying to avoid side effects like that?). My functions are: val f: NEL[Int] => String = (l: NEL[Int]) => {println("f: " + l); l.toString |+| "X" } val g: NEL[String] => BigInt = (l: NEL[String]) => {println("g: " + l); BigInt(l.map(_.length).sum) } Then I combine them via a cokleisli and pass in a NEL[Int] val k = cokleisli(f) =>= cokleisli(g) println("RES: " + k( NEL(1, 2, 3) )) What does this print? f: NonEmptyList(1, 2, 3) f: NonEmptyList(2, 3) f: NonEmptyList(3) g: NonEmptyList(NonEmptyList(1, 2, 3)X, NonEmptyList(2, 3)X, NonEmptyList(3)X) RES: 57 The RES value is the character count of the (String) elements in the final NEL. Two things occur to me: How could I have known that my NEL was going to be reduced in this manner from the method signatures involved? (I wasn't expecting the result at all) What is the point of this? Can a reasonably simple and easy-to-follow use case be distilled for me? This question is a thinly-veiled plea for some lovely person like retronym to explain how this powerful library actually works.

  • ORM model and DAO in my particular case

    - by EugeneP
    I have the DB structure as follows: table STUDENT (say, id, surname, etc) table STUDENT_PROPERTIES (say, name_of_the_property:char, value_of_the_property:char, student_id:FK) table COURSE (id, name, statusofcourse_id) table STATUSOFCOURSE (id, name_of_status:char ('active','inactive','suspended' etc)) table STUDENT_COURSE (student_id,course_id,statusofcourse_id) Let's try to pick up domain objects in my database: Student and Course are main entities. Student has a list of courses he attends, also he has a list of properties, that is all for this student. Next, Course entitity. It may contain a list of students that attend it. But in fact, the whole structure looks like this: the starting point is Student, with it's PK we can look a list of his properties, then we look into the STUDENT_COURSE and extract both FK of the Course entity and also the Status of the combination, it would look like "Student named bla bla, with all his properties, attends math and the status of it is "ACTIVE". now, quotation 1) Each DAO instance is responsible for one primary domain object or entity. If a domain object has an independent lifecycle, it should have its own DAO. 2) The DAO is responsible for creations, reads (by primary key), updates, and deletions -- that is, CRUD -- on the domain object. Now, first question is What are entities in my case? Student, Course, Student_Course, Status = all except for StudentProperties? Do I have to create a separate DAO for every object?

  • A business Case for Enterprise Python

    - by Srirangan
    Hi all, This will not be a "programming" question but more technology / platform related question. I'm trying to figure out whether Python can be a suitable Java alternative for enterprise / web applications. Which are the ideal cases where you would prefer to use Python instead of Java? How would a typical Python web application (databases/sessions/concurrency) perform as compared to a typical Java application? How do specific Python frameworks square up against Java based frameworks (Spring, SEAM, Grails etc.)? For businesses, switching from the Java infrastructure to a Python infrastructure .. is it too hard/expensive/resource intensive/not viable? Also shed some light on the business case for providing a Python + Google AppEngine based solution to the end customer. Will it be cost effective in an typical scenario? Sorry if I am asking too wide a question, I would have liked to keep it specific, but I need your help to evaluate Python as a whole from the perspectives of the programmers, service providing company and end business customer. For an SME, a Python/GoogleAppEngine based technology stack is a clear scalable and affordable platform. But what about a large MNC that already has a lot invested in Java. Thank you so much. I am researching this myself and will gladly share my conclusions here! Thank you, Srirangan

  • Entity Framework Performance Inconsistency Compared to Sql Management Studio

    - by AndyV
    I'm getting timeouts with a very basic EF statement. I'm simply doing a select from a single table with a Entity.Title.StartsWith("test") and a .Take(25). When I run this for a search that returns no results I get a timeout. If I profile and grab the sql statement it looks fine, and if I run that sql in Management Studio it runs in a fraction of a second! Why would the same query run sub-second in Management Studio and timeout when generated by EF and called from an Asp.Net app?

  • average case running time of linear search algorithm

    - by Brahadeesh
    Hi all. I am trying to derive the average case running time for deterministic linear search algorithm. The algorithm searches an element x in an unsorted array A in the order A[1], A[2], A[3]...A[n]. It stops when it finds the element x or proceeds until it reaches the end of the array. I searched on wikipedia and the answer given was (n+1)/(k+1) where k is the number of times x is present in the array. I approached in another way and am getting a different answer. Can anyone please give me the correct proof and also let me know whats wrong with my method? E(T)= 1*P(1) + 2*P(2) + 3*P(3) ....+ n*P(n) where P(i) is the probability that the algorithm runs for 'i' time (i.e. compares 'i' elements). P(i)= (n-i)C(k-1) * (n-k)! / n! Here, (n-i)C(k-1) is (n-i) Choose (k-1). As the algorithm has reached the ith step, the rest of k-1 x's must be in the last n-i elements. Hence (n-i)C(k-i). (n-k)! is the total number of ways of arranging the rest non x numbers, and n! is the total number of ways of arranging the n elements in the array. I am not getting (n+1)/(k+1) on simplifying.

  • How to sync with eclipse target management?

    - by SpliFF
    I've been using the Jcraft SFTP plugin for Team Synchronisation up till now but I ran across a rumour it's being deprecated by "Target Management". Still, despite my best efforts I haven't found any information on HOW you are supposed to setup a sync with RSE/Target Management. Can anybody provide a step-by-step guide or at least clarification on whether this is actually possible right now or just a planned feature. I do my testing locally then sync to the remote - which may have changes made by other users. I want to be able to see differences and deal with conflicts etc just like with the current Team Synchronization framework.

  • Word VBA - Find text between delimiters and convert to lower case

    - by jJack
    I would like to find text which is between the < and characters, and then turn any found text into "normal" case, where first letter of word is capitalized. Here is what I have thus far: Function findTextBetweenCarots() As String Dim strText As String With Selection .Find.Text = "<" ' what about <[^0-9]+> ? .Find.Forward = True .Find.Wrap = wdFindContinue End With Selection.Find.Execute ' Application.Selection. ' how do I get the text between the other ">"? findCarotSymb = Application.Selection.Text End Function Or, is there a better way of doing this? I also approached the problem using the VBScript Regex 5.5 library, which worked on simple documents, but not on certain documents with complex tables. For example, trying to just bold the text (for simplicity): Sub BoldUpperCaseWords() Dim regEx, Match, Matches Dim rngRange As Range Set regEx = New RegExp regEx.Pattern = "<[^0-9]+>" regEx.IgnoreCase = False regEx.Global = True Set Matches = regEx.Execute(ActiveDocument.Range.Text) For Each Match In Matches ActiveDocument.Range(Match.FirstIndex, Match.FirstIndex + Len(Match.Value)).Bold = True Next End Sub would not work in a document with tables. In fact, it would not even bold the correct text (the text between the <. This leads me to believe I have a broader issue here that I am missing. Here is what a sample doc looks like. Notice the wrong text is bold:

  • What is the JavaScript variable scope in a switch / case statment?

    - by Todd Moses
    While creating JavaScript with ASP.NET MVC I noticed several scope warnings and realized that I am missing something with understanding the variable scope inside the switch / case statement. Warning: 'i' is already defined referring to case b and case c My code looks similar to this: switch(element) { case 'a': for(var i=0; i < count; i++){ do something } break; case 'b': for(var i=0; i < count; i++){ do something } break; case 'c': for(var i=0; i < count; i++){ do something } break; } I thought scope ended with each break statement but it seems that scope does not end until the end of the switch/case. Is scope for the entire switch/case?

  • Anybody makes stylish PC cases that look like the Cobalt Cube?

    - by OverTheRainbow
    Hello I'm looking for computer cases that don't look like regular PC's in case customers would like to keep it on their desktop so it has to look stylish. I liked the Cobalt Cube: http://en.wikipedia.org/wiki/Cobalt_Qube Does someone know if some company makes cases that look the same (I know about Shuttle : they're too pricey), and possibly one that has a really quiet power supply? Thank you.

  • What is the best way to convince management that virtualization isn't always appropriate in producti

    - by uncle brad
    I work for a small company with a .NET product that was acquired by a medium sized company with "big iron" products. Recently, the medium-sized part of the company acquired another small company with a similar .NET product and management went to have a look at their technology. They make heavy use of virtualization in their production environment and it's been decided that we will too. Our product was not designed to be run in a virtual environment, but some accommodations can be made. For instance; there are times when we're resource bound due to customer initiated processes. This initiation is "bursty" by nature, but the processing can be made asynchronous and throttled. This is something that would need to be done for scalability anyway. But there is other processing that we do that isn't so easily modified because we're resource bound for extended periods of time. How do I convince management that heavy use of virtualization is probably not appropriate for us?
