• Eclipse Code Templates with Cobol

  - by Bruno Brant

  People, My team is just beginning to learn how to use COBOL on Eclipse (as part of the Rational Developer for System Z package) and one of our most desired features are code templates or code snippets. What we'd like to have is a code completion based on snippets just like we have on Java. For example, when I type try and hit ctrl-space Eclipse shows me a list of completion options, where one of those is create a try/catch block. Well, in COBOL one could leverage this when creating, for example, embedded SQL blocks, like EXEC SQL SELECT field, field, field, FROM table WHERE field = value, field = value END-EXEC. However, for some reason, it seems that Eclipse treats COBOL a little differently (no wonder why) from other languages. As such, when looking for the code templates in the preferences menu for COBOL, its appearance is very different from the Java one. The question is: how does one uses Eclipse's code templates with COBOL?

• Comparison of Code Review Tools/Systems

  - by SytS

  There are a number of tools/systems available aimed at streamlining and enhancing the code review process, including: CodeStriker Review Board, code review system in use at VMWare Code Collaborator, commercial product by SmartBear Rietveld, based on Modrian, the code review system in use at Google Crucible, commercial product by Atlassian These systems all have varying feature sets, and differ in degrees of maturity and polish; the selection is a little bewildering for someone who is evaluating code review systems for the frist time. Some of these tools have already been mentioned in other questions/answers on StackOverflow, but I would like to see a more comprehensive comparison of the more popular systems, especially with respect to: integration with source control systems integration with bug tracking systems supported workflow (reviews pre/post commit, review or contiguous/non-contigous revision ranges, etc) deployment/maintenance requirements

• How do I get developers to treat test code as "real" code?

  - by womp

  In the last two companies I've been at, there is an overriding mentality among developers that it's okay to write unit tests in a throw-away style. Code that they would never write in the actual product suddenly becomes OK in the unit tests. I'm talking Rampant copying and pasting between tests Code styling rules not followed Hard-coded magic strings across tests No object-oriented thought or design for integration tests, mocks or helper objects (250 line single-function tests!) .. and so on. I'm highly dissatisfied with the quality of the test code. Generally we do not do code reviews on our test assemblies, and we also do not enforce style or code analysis of them on our build server. Is that the only way to overcome this inertia about test quality? I'm looking for ideas to take to our developers, without having to go to higher management saying that we need to use resources for enforcement of test quality (although I will if I have to). Any thoughts or similar experiences?

• Tool to convert inline C# into a code behind file

  - by Jon Jones

  Hi I have a number of legacy web controls (ascx) that contains huge amounts of inline C#. The forms contain a number of repeated and duplicate code. Our first plan is to move the code into code behinds per file, then refactor etc... were doing this to upgrade the client to the latest version of their cms At the moment we are going to have to manually copy and paste from hundreds of files, create a code behind, copy the code, add the namespaces based on the client-side imports and then do any tidying up does anybody PLEASE know of a tool that can do the majority of this work for us ? Thanks

• Excluding standard directories from code coverage results with C++/CLI

  - by brickner

  I have a Visual Studio 2010 .NET 4 solution with C# projects and a C++/CLI project. I use Visual Studio's built in unit tests and code coverage. Other than the fact that Visual Studio 2010 coverage tool for C++/CLI projects seems to be much weaker than Visual Studio 2008 coverage tool, I get weird results. For example, I get uncovered code in this file: c:\program files (x86)\microsoft visual studio 10.0\vc\include\xstring And some other files in that directory. I want to exclude this code from coverage results. Is there a way to put some exclude attributes on that code? If not, is there a different automatic way to exclude that code from coverage? If not, is there a way to use EXCLUDE option to exclude it? Can it be done automatically within Visual Studio without running the coverage tool from command prompt? Any other solutions?

• Tools for code snippet execution

  - by nzpcmad

  By "code snippet execution", I mean the ability to write a few lines of code, run and test it without having to fire up an IDE and create a dummy project. It's incredibly useful for helping people with a small code sample without creating a project, compiling everything cleanly, sending them the code snippet and deleting the project. I'm not asking about the best code snippets or a snippet editor or where to store snippets! For C#, I use Snippet Compiler. For Java, I use Eclipse Scrapbook. For LINQ, I use LINQPad. Any suggestions for other (better?) tools? e.g. is there one for Java that doesn't involve firing up Eclipse? What about C?

• Decoding equivalent assembly code of C code...

  - by puffadder

  Hi All, Wanting to see the output of the compiler (in assembly) for some C code, I wrote a simple program in C and generated its assembly file using gcc. The code is this: #include <stdio.h> int main() { int i = 0; if ( i == 0 ) { printf("testing\n"); } return 0; } The generated assembly for it is here (only the main function): _main: pushl %ebpz movl %esp, %ebp subl $24, %esp andl $-16, %esp movl $0, %eax addl $15, %eax addl $15, %eax shrl $4, %eax sall $4, %eax movl %eax, -8(%ebp) movl -8(%ebp), %eax call __alloca call ___main movl $0, -4(%ebp) cmpl $0, -4(%ebp) jne L2 movl $LC0, (%esp) call _printf L2: movl $0, %eax leave ret I am at an absolute loss to correlate the C code and assembly code. All that the code has to do is store 0 in a register and compare it with a constant 0 and take suitable action. But what is going on in the assembly ? Thanks in advance.

• Visual Studios Team System 2008 Code Coverage Window Closes

  - by ThoughtCrhyme

  Trying to run the code coverage tool in Visual Studios for a set of unit tests. Adam from Think First, Code Later has had the same problem: I wanted to get the code coverage metrics for the project. Naturally, I fire up the solution in Visual Studio 2008, go to the Test menu, click Edit Test Run Configurations, and click Local Test Run. I then click Code Coverage to turn on code coverage for a given assembly and POOF the Local Test Run Configraution window just disappears. He recommends installing this hotfix to fix the problem, however a) when I run that hotfix I get the message “None of the products that are addressed by this software update are installed on this computer. Click Cancel to exit setup.” and b) there is no Silverlight in our solution. Any other ideas for a fix?

• How to keep code maintainable after original programmer quit

  - by Stan

  Say if it's a 10 people project, 2-3 of the original programmer quit after the project has been release a stable version for a while. How to have the code maintainable in this case? My imagination is reviewing the code after the project goes to release version and keep review it afterwards? Maybe split into 2-3 small groups and have each group review part of the code. So at least 3-4 people are familiar with part of code. Does this work? How do companies deal with this issue? Usually how many percentage of time spent on reviewing the code? Please advise, thanks to community.

• Suggestions for displaying code on webpages, MUST use <br> for newline

  - by bguiz

  Hi, I want to post code snippets online (wordpress.com blog) - and have its whitespace formatted nicely. See the answers suggested by this other SO question: Those would be OK, except that I like to copy code to clip board or clip entire pages using Evernote - and they use either the <pre> tag or <table> (or both) to format the code. So I end up with text whose newlines and white spaces ignored, e.g. string url = "<a href=\"" + someObj.getUrl() + "\" target=\"_blank\">"; // single line comments // second single line override protected void OnLoad(EventArgs e) { if(Attributes["class"]&nbsp;!= null) { //_year.CssClass = _month.CssClass = _day.CssClass = Attributes["class"]; } base.OnLoad(e); } Which I find rather annoying myself. I find that if the code was formatted using <br> tags, they copy/ clip porperly, e.g. string url = "<a href=\"" + someObj.getUrl() + "\" target=\"_blank\">"; // single line comments // second single line override protected void OnLoad(EventArgs e) { if(Attributes["class"]&nbsp;!= null) { //_year.CssClass = _month.CssClass = _day.CssClass = Attributes["class"]; } base.OnLoad(e); } I find this annoying myself, so I don't want to inflict it upon others when I post my own code. Please suggest methods of posting code snippets online that are able to do this. I would like to emphasise that syntax highlighting capability is secondary to correct white space markup. Thank you

• php: how to return an HTTP 500 code on any error, no matter what

  - by Jake

  Hi guys. I'm writing an authentication script in PHP, to be called as an API, that needs to return 200 only in the case that it approves the request, and 403 (Forbidden) or 500 otherwise. The problem I'm running into is that php returns 200 in the case of error conditions, outputting the error as html instead. How can I make absolutely sure that php will return an HTTP 500 code unless I explicitly return the HTTP 200 or HTTP 403 myself? In other words, I want to turn any and all warning or error conditions into 500s, no exceptions, so that the default case is rejecting the authentication request, and the exception is approving it with a 200 code. I've fiddled with set_error_handler() and error_reporting(), but so far no luck. For example, if the code outputs something before I send the HTTP response code, PHP naturally reports that you can't modify header information after outputting anything. However, this is reported by PHP as a 200 response code with html explaining the problem. I need even this kind of thing to be turned into a 500 code. Is this possible in PHP? Or do I need to do this at a higher level like using mod_rewrite somehow? If that's the case, any idea how I'd set that up? Thanks for any help. Jake

• Reading Code - helpful visualizers and browser tools

  - by wishi_

  Hi! I find myself reading 10 times more code than writing. My IDEs all are optimized to make me edit code - with completion, code assist, outlines etc. However if I'm checking out a completely new project: getting into the application's logics isn't optimized with these IDE features. Because I cannot extend what I don't fully understand. If you for example check out a relatively new project, frama-c, you realize that it has got plugins that are helpful to gain insight into "unfamiliar code": http://frama-c.com/plugins.html - However of course the project has a different scope. What I'm fully aware of. I'm looking for something that does helpful things for code-reading. Like: providing a graph, - reverse engineering UML e g., showing variable scopes showing which parts are affected by attempted modifications visualizing data-flow semantics showing tag-lists of heavily utilized functions ... My hope is that something like that exists. - That there're some Eclipse plugins I don't know or that there's a code-browser that has some of these features?

• How To Go About Updating Old C Code

  - by Ben313

  Hello: I have been working on some 10 year old C code at my job this week, and after implementing a few changes, I went to the boss and asked if he needed anything else done. Thats when he dropped the bomb. My next task was to go through the 7000 or so lines and understand more of the code, AND, to modularize the code somewhat. I asked him how he would like the source code modularized, and he said to start putting the old C code into c++ classes. Being a good worker, I nodded my head yes, and went back to my desk, where I sit now, wondering how in the world to take this code, and "modularize" it. Its already in 20 source files, each with its own purpose and function. in addition, there are three "main" structs. each of these stuctures has 30 plus fields, many of them being other, smaller sturcts. Its a complete mess to try to understand, but almost every single function in the program is passed a pointer to one of the structs, and uses the struct heavily. Is there any clean way for me to shoehorn this into classes? I am resolved to do it if it can be done, I just have no idea how to begin.

• How to best integrate generated code

  - by Arne

  I am evaluating the use of code generation for my flight simulation project. More specifically there is a requirement to allow "the average engineer" (no offense I am one myself) to define the differential equations that describe the dynamic system in a more natural syntax than C++ provides. The idea is to devise a abstract descriptor language that can be easily understood and edited to generate C++ code from. This descriptor is supplied by the modeling engineer and used by the ones implementing and maintaining the simulation evironment to generate code. I've got something like this in mind: model Aircraft has state x1, x2; state x3; input double : u; input bool : flag1, flag2; algebraic double : x1x2; model Engine : tw1, tw2; model Gear : gear; model ISA : isa; trim routine HorizontalFight; trim routine OnGround, General; constant double : c1, c2; constant int : ci1; begin differential equations x1' = x1 + 2.*x2; x2' = x2 + x1x2; begin algebraic equations x1x2 = x1*x2 + x1'; end model It is important to retain the flexibility of the C language thus the descriptor language is meant to only define certain parts of the definition and implementation of the model class. This way one enigneer provides the model in from of the descriptor language as examplified above and the maintenance enigneer will add all the code to read parameters from files, start/stop/pause the execution of the simulation and how a concrete object gets instatiated. My first though is to either generate two files from the descriptor file: one .h file containing declarations and one .cpp file containing the implementation of certain functions. These then need to be #included at appropriate places [File Aircarft.h] class Aircraft { public: void Aircraft(..); // hand-written constructor void ReadParameters(string &file_name); // hand-written private: /* more hand wirtten boiler-plate code */ /* generate declarations follow */ #include "Aircraft.generated.decl" }; [File Aircraft.cpp] Aircarft::Aircraft(..) { /* hand-written constructer implementation */ } /* more hand-written implementation code */ /* generated implementation code follows */ #include "Aircraft.generated.impl" Any thoughts or suggestions?

• How to consistently enable screen sharing with iChat

  - by Joel

  I am unable to consistently get screen sharing in iChat to work. When I select an online buddy, under the Buddies menu the options "Share my screen with Bob" and "Ask to Share Bob's Screen" are disabled. Sometimes starting a chat with that person will enable the screen sharing but often not. Once its enabled it works fine but I have no idea what the key is to getting it enabled. It seems fairly random when it works. This is over the public internet using Google Talk. Both ends are running OSX 10.5.

• Driverless printer sharing on Windows.

  - by MiffTheFox

  I have a printer hooked up to a computer running Windows XP. It prints fine from that computer, but I'd like to set up other computers (running Vista and 7) to print from it as well. I tried setting up printer sharing, but it wouldn't work because the client computers needed to install the print driver as well. (The driver itself has been discontinued and there's no version for Vista or 7.) Is there some (hopefully free) software I can install to, say, add a virtual printer that sends the data to a host computer to print it, rather then having to directly access the printer over the network via the Windows printer sharing model?

• Sharing laptop's internal optical drive running windows XP Media Center Edition with Netbook running

  - by Col

  just got a new HP netbook with no optical drive and guide said I should be able to share the optical drive of another windows computer. The netbook is running Windows 7 and the laptop, also HP, with the internal optical drive is running Windows XP Media Center Edition. I have wireless network that both the laptop and netbook access without a problem. The instructions did not seem to work in my case. When I right clicked on Properties of the optical drive and went to the Sharing tab, there was no selction for Advanced Sharing as the instructions said. XP made me go to Network wizard and set up a network, (which I already had). After doing that I could not access the drive from Windows 7. Has anyone benn able to do this?

• Media Sharing on Windows Server 2008 R2

  - by HCL

  I want a Server 2008R2 (x64) to act as DNLA-Server. I remember I tried this with a Server 2008 about two years ago and this was only possible with some ugly hacks. Is it on Server 2008R2 now possible to enable Windows MediaPlayer Media-Sharing by installing the desktop experience packet? Has someone already experience on this. Or is there another possibility to allow media sharing on a Server 2008R2 "the designated way"? I remember that on Server 2008 the way was to install the old MediaConnect-Pacakge. But I hesitate to install such a component on a server. Anciently I installed VirtualServer with Vista and enabled the media server there in, but this seems to me somewhat overkill for such a simple task.

• Sharing Internet Connection in Windows 7 is so much more frustrated than Windows XP

  - by Phuong Nguyen

  Back to the time of Windows XP, from Properties dialog of my Wireless Connection, I can enable sharing and then select LAN network from the Drop Down List and boom, I can share it with my friend. We just need a LAN cable (either cross or not-cross is OK) and his Laptop will get an auto IP to gain access to internet. But now with the new Windows 7, everything starts to suck. I cannot see the Drop Down List any more in the sharing panel and my friends Laptop cannot get an automatic IP anymore. Am I doing anything wrong over there? How can I gain back the peace I used to have with Windows XP?

• Improve performance on Lync desktop sharing

  - by Trikks

  I'm using Lync 2010 server to handle some clients communication and screen sharing. The biggest issue is the performance with screen sharing, it is of rather high quality but the frame rate is very poor. I have been reading and searching a lot on the subject and 95% of all topics is about bandwidth, we have a 200/200 MBit Internet connection solely for this application. Also my test machines runs on an internal gigabit lan. The speeds between all boxes is hysterically fast. Next step was to ensure that there where some profiles for different bandwidths, so i registered some New-CsNetworkBandwidthPolicyProfile -Identity 50Mb_Link -Description "BW profile for 50Mb links" -AudioBWLimit 20000 -AudioBWSessionLimit 200 -VideoBWLimit 14000 -VideoBWSessionLimit 700 New-CsNetworkBandwidthPolicyProfile -Identity 100Mb_Link -Description "BW profile for 100Mb links" -AudioBWLimit 30000 -AudioBWSessionLimit 300 -VideoBWLimit 25000 -VideoBWSessionLimit 1500 Nothing fancy happend here either. Non of the test boxes have anything from Norton installed, they doesn't have any firewalls running (nor does the Lync server), all fences are down in this environment just for the testing. Is there any thing that I may have missed to improve the quality of this? Thanks

• Inbound connections using Internet Connection Sharing in Apple/Mac/Leopard

  - by tlianza

  I have a Mac mini which I'm using to give some other devices wireless access, by sharing it's Airport connection with the local ethernet, and that is plugged into a switch. All devices can get online no problem. (See how: http://www.macosxhints.com/article.php?story=20041112101646643 and http://www.macosxhints.com/article.php?story=20071223001432304 ) The issue is that I need to be able to connect in to these machines as well (at least, for the Slingbox to work). All the devices have 192.168.2.* addresses, and the rest of my local network is on 192.168.1.*. I tried setting a static route so that the 192.168.2.* addresses would use a gateway of 192.168.1.50 (my mac mini's address) but that didn't seem to help. Does anyone know if what I'm trying to do is possible? I admit I'm not certain what Internet Connection sharing is really doing under the hood... perhaps it just does basic nat, and doesn't do the type of routing I'm looking for. If so, anyone know if this is possible?

• Sharing internet through a wireless ad-hoc in Windows 7

  - by vzait

  I'm actually requesting a workaround to share a PPoE wired Internet connection between two laptops using wireless. I've tried sharing it the usual way... New Ad-hoc = Click turn On sharing = etc. I've tried changing all the settings I could find related to the two networks on both machines. Conclusion: Sometimes it works, sometimes it doesn't. Is it really buggy, or are my hands growing from the wrong place? I'm almost sure I'm not the only one having this kind of problem. What is the easiest/correct workaround ?

• Apple Remote Desktop and Screen Sharing

  - by jfm429

  We have a Mac OS 10.8.2 server that we want to be able to administer with Apple Remote Desktop. At the same time, we want normal users to be able to access their account screens (through background login) without being able to view the current screen. However, in order to enable this (by enabling the "normal" Screen Sharing option in System Preferences) Remote Desktop needs to be disabled. The question is - how can we run both Remote Desktop for administrators and VNC screen sharing for normal users while restricting normal users to logging in on a background window instead of viewing the front screen?
