• Just an experiment changing the application data path

  - by Arthur

  When I change the Appication Data path in windows xp registry to a network folder I get this error message on the next system startup: "windows cannot load the user's profile but has logged you with the default profile system" The registry keys are: "[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders]" "[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders]" under the names "AppData" and "Local AppData" I dont care if "Windows logins you with the default profile system" but is there a way to disable that message, or change the message timeout form 30 seconds to 0?,or maybe create an script that changes the Application Data path every system startup? P.S. The computer with the shared folder is always on.

• Visual Studio - How to use an existing vsproj's project settings as a template for new project?

  - by Jakobud

  There is some software I want to write a plugin for. The software includes some sample plugins. I want to create a new fresh project but I want to use one of the sample plugin vsproj's project settings as a template. It doesn't seem very clear on how to do this. If I do "New Project From Existing Code" that only imports the cpp, h, etc files into the new project. Right now the only way I can see to copy a sample projects settings is to open two instances of VS2005 next to each other and simply mimic the settings... Surely there is a built in method of doing this?

• <thead> and <tfoot> in Safari

  - by AJ

  I trying to print a page with multiple tables. The problem is that any of these tables may break and carry over to the next page. Have been trying to get the table header to repeat on the second page. Am currently using thead and setting the display property to table-header-group. This works just as expected in IE and firefox but the header will not repeat in Safari. Since we are using software that converts our page to a pdf document for printing...and the 3rd party software uses a Safari engine, we are stuck with this problem. Does anyone know a way / workaround to make headers repeat if the table spans multiple pages in Safari?

• Where can I find the transaction protocol used by Automated Teller Machines?

  - by Dave

  I'm doing a grad-school software engineering project and I'm looking for the protocol that governs communications between ATMs and bank networks. I've been googling for quite a while now, and though I'm finding all sorts of interesting information about ATMs, I'm surprised to find that there seems to be no industry standard for high-level communications. I'm not talking about 3DES or low-level transmission protocols, but something along the lines of an Interface Control Document; something that governs the sequence of events for various transactions: verify credentials, withdrawal, check balance, etc. Any ideas? Does anything like this even exist? I can't believe that after all this time the banks and ATM manufacturers are still just making this up as they go. A shorter question: if I wanted to go into the ATM software manufacturing business, where would I start looking for standards?

• Receiving Text From Another Application

  - by Garry

  Hi, I'm building some home automation software with Cocoa/Objective-C. The main application will have a minimal GUI and will most likely be represented by a status bar icon only. I'm using proprietary speech-to-text software (MacSpeech Dictate) that takes my voice command and converts it to plain text. I then need to send this plain text to my app for parsing. Is there a way to send a string to a Cocoa application? Could AppleScript achieve this? How would I make the NSString string in my app "available" to receive the passed string? For reasons that are beyond the scope of this question - it is not possible to dictate the command directly into my app. Many thanks in advance,

• Is Amazon SQS the right choice here? Rails performance issue.

  - by ole_berlin

  I'm close to releasing a rails app with the common networking features (messaging, wall, etc.). I want to use some kind of background processing (most likely Bj) for off-loading tasks from the request/response cycle. This would happen when users invite friends via email to join and for email notifications. I'm not sure if I should just drop these invites and notifications in my Database, using a model and then just process it with a worker process every x minutes or if I should go for Amazon SQS, storing the messages and invites there and let my worker retrieve it from Amazon SQS for processing (sending the invites / notifications). The Amazon approach would get load off my Database but I guess it is slower to retrieve messages from there. What do you think?

• Does anyone know where I could find a 2 input USB voltage meter?

  - by John O

  What we really need is a tiny UPS, of sorts. We'll be hooking up a solar cell and a battery to a single board computer. Currently, that SBC is a custom Pic32 device, and it does it's own UPS and voltage monitoring duties. I've been tasked with trying to replicate all of its features with off the shelf products... and for the most part I've succeeded. But I don't currently have any way to switch between two sources of juice, or monitor when they're getting low. These guys have something: http://www.mini-box.com/picoUPS-100-12V-DC-micro-UPS-system-battery-backup-system I really like it, the price is well within the budget. We might even work it in though it does 12V and I'll probably be using 5V... there are enough engineers on hand to figure out something. But I'd still have no idea what the voltage was for the PV or battery. I was hoping that there was some simple little USB multimeter thing that I could use to monitor this with, but I can't seem to come up with anything. I've found all sorts of cool hardware, but nothing that will help us. Does anyone know of anything?

• How do I disable maven build when using Maven 2.0 integration for eclipse?

  - by Stein G. Strindhaug

  How do I stop the "Maven 2.0 integration" plugin from running maven build, while keeping "build automatically" checked? I'm pretty sure it used to be some check box to disable maven build before, but after upgrading Ubuntu; eclipse seems to have been updated in the process, and now I cannot find any way to turn off the maven build. The maven build takes literally minutes (about 5 minutes or so), while just running java build used to finish in seconds. Is it no longer possible to disable it or have they just hidden it well? If it's not possible, will eclipse be able to compile my maven project without the plugin? (Trying to google for a solution the closes I got to an answer was several archives of this old post where the answer essentially were "You should be able to disable Maven builder in project preferences..." which doesn't really help because I cannot find any on/off settings there)

• C# StandardInput Sending Mofidiers

  - by Paul Oakham

  Hi All, We have some legacy software which depends on sending keystrokes to a DOS window and then scraping the screen. I am trying to re-create the software by redirecting the input and output streams of the process directly to my application. This part I have managed fine using: _Process = new Process(); { _Process.StartInfo.FileName = APPLICATION; _Process.StartInfo.RedirectStandardOutput = true; _Process.StartInfo.RedirectStandardInput = true; _Process.StartInfo.RedirectStandardError = true; _Process.StartInfo.UseShellExecute = false; _Process.StartInfo.CreateNoWindow = true; _Process.OutputDataReceived += new DataReceivedEventHandler(_Process_OutputDataReceived); _Process.ErrorDataReceived += new DataReceivedEventHandler(_Process_ErrorDataReceived); } My problem is I need to send some command modifiers such as Ctrl, ALT and Space as well as F1-12 to this process but am unsure how. I can send basic text and I receive response's fine. I just need to emulate these modifiers. Any help would be great, Cheers

• .net Compiler Optimizations

  - by Dested

  I am writing an application that I need to run at incredibly low speeds. The application creates and destroys memory in creative ways throughout its run, and it works just fine. I am wondering what compiler optimizations occur so I can try to build to that. One trick off hand is that the CLR handles arrays much faster than lists, so if you need to handle a ton of elements in a List, you may be better off calling ToArray() and handling it rather than calling ElementAt() again and again. I am wondering if there is any sort of comprehensive list for this kind of thing, or maybe the SO community can create one :-)

• C++ build systems

  - by flo

  I will start a new C++ project (it may have some C components as well) soon and I am looking for a modern, industrial-strength (i.e. non-beta) build system. The software will be created by several developers in 3-5 years and will run on Linux (Mac OS X and Windows might be supported later). I am looking for something that has better comprehensibility, ease-of-use and maintainability than e.g. make but is still powerful enough to handle a complex project. Open source software is preferred. I started looking into Boost.Build, CMake, Maven and SCons so far and liked features and concepts of all of those, but I'm lacking the experience to make a decision for a large project.

• Spring MVC JSP Parameters

  - by zpinter

  I'm looking to turn off try blocks for a specific JSP page (though turning it off globally would be OK as well). From what I've gathered, it looks something like this: <jsp-param> <param-name>noTryBlocks</param-name> <param-value>true</param-value> </jsp-param> However, everywhere I see that sample it's for a weblogic.xml file. Does anybody know how I can set this JSP parameters for a Spring MVC application? web.xml? Perhaps somewhere near here?: <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean>

• Which technology(s) / language(s) to write linux web application/service? [closed]

  - by Lee Tickett

  I am currently playing with some open source home automation software www.domotiga.nl The software is built in Gambas2 (a graphical programming language similar to visual basic). I am considering building something similar or porting domotiga to a server based application/service. The application would need a web front end and i will likely be developing in debian (arm). But i'm not sure if php or python are suitable for server based applications which need to be always running (collecting data etc) rather than just running when accessed. Which technology(s) / language(s) would you suggest i look into? I used to do a lot of Visual Basic, then VB.NET, now C# and have played with php a few years back- but don't really want this to sway the decision too much as i should be able to pickup whatever language if i decide to proceed.

• How do I add a WSDL to a Visual Studio 2005 project?

  - by Ben McCormack

  One of our vendors provides a web service API to allow their customers to validate data in a database. As part of their SDK, they provide a WSDL (Web Service Definition Language) file that, according to their documentation, can "be read by software applications and application development tools. An application tool such as Microsoft's Visual Studio can import a WSDL document and automatically generate software classes that access the Web Services the WSDL defines." I'm currently using Visual Studio 2005. What do I need to do to get Visual Studio to do the magic code generation for me?

• Copy an array backwards? Array.Copy?

  - by daniel

  I have a List<T> that I want to be able to copy to an array backwards, meaning start from List.Count and copy maybe 5 items starting at the end of the list and working its way backwards. I could do this with a simple reverse for loop; however there is probably a faster/more efficient way of doing this so I thought I should ask. Can I use Array.Copy somehow? Originally I was using a Queue as that pops it off in the correct order I need, but I now need to pop off multiple items at once into an array and I thought a list would be faster.

• TeamCity build triggers don't automatically run

  - by Phil.Wheeler

  I've been playing around with and learning a bit about TeamCity and have the server correctly set up with my .Net MVC project committed in Subversion successfully and build configurations and triggers sorted to kick off when any changes are committed to the repository. TeamCity polls on its default time period and is picking up that changes have been committed, but it is adding these to the queue without actually ever running them. I have to manually click the "Run" button to kick them off. What setting do I need to change in order to ensure that any new changes are automatically run?

• MS Access 07 - Q re lookup column vs many-to-many; Q re checkboxes in many-to-many forms

  - by TBinLondon

  Hello, I'm creating a database with Access. This is just a test database, similar to my requirements, so I can get my skills up before creating one for work. I've created a database for a fictional school as this is a good playground and rich data (many students have many subjects have many teachers, etc). Question 1 What is the difference, if any, between using a Lookup column and a many-to-many associate table? Example: I have Tables 'Teacher' and 'Subject'. Many teachers have many subjects. I can, and have, created a table 'Teacher_Subject' and run queries with this. I have then created a lookup column in teachers table with data from subjects. The lookup column seems to take the place of the teacher_subject table. (though the data on relationships is obviously duplicated between lookup table and teacher_subject and may vary). Which one is the 'better' option? Is there a snag with using lookup tables? (I realize that this is a very 'general' question. Links to other resources and answers saying 'that depends...' are appreciated) Question 2 What attracts me to lookup tables is the following: When creating a form for entering subjects for teachers, with lookup I can simply create checkboxes and click a subject for a teacher 'on' or 'off'. Each click on/off creates/removes a record in the lookup column (which replaces teacher_subject). If I use a form from a query from teacher subject with teacher as main form and subject as subform I run into this problem: In the subform I can either select each subject that teacher has in a bombo box, i.e. click, scroll down, select, go to next row, click, scroll down, etc. (takes too long) OR I can create a list box listing all available subjects in each row but allowing me to select only one. (takes up too much space). Is it possible to have a click on/off list box for teacher_subject, creating/removing a record there with each click? Note - I know zero SQL or VB. If the correct answer is "you need to know SQL for this" then that's cool. I just need to know. Thanks!

• Would the world be a better place if there were only one programming language?

  - by Simon

  Well, perhaps not the world, but would it encourage more-re-use, less replication of basic code, or at least an uplift in what is considered basic code, more time advancing the application science and a greater encouragement to share, a more advanced base of understanding for new programmers, since the language could be taught ubiquitously and patterns of teaching would have emerged which were optimised for students learning etc etc? I think all of those things would make the programming world better and would probably have significant commercial benefit too. This is definitely not a religious debate about which language is best, and is predicated on the notion of some super-being having designed the perfect language to start with, which was improbable, but it strikes me that if, from the beginning, there were only a single programming language we may be further along in terms of the evolution of the software industry and software science. And although it is now impossible, if you buy some or all of these assertions is there an argument for standardising on a single language for the future so we can accelerate our collective progress rather than all of us re-inventing some part of the same wheel and consigning our children to the same fate?

• How to make your website works on a projector?

  - by iyad al aqel

  I have a presentation tomorrow, and while I was trying to project my website using projector all the elements appeared mixed up. The problem is I used a software called "AXURE" to do the website. The HTML files produced by this software are crap. There's no one unified CSS file. The style is embedded for each element in the <div> tag and every element is positined by absolute pixels. How can make my website works on larger screens?

• Migrating from mssql to firebird: pro and cons

  - by user193655

  i am considering the migration for 3 reasons: 1) SQLSERVER installation is a nightmar, expecially for 1-user software. Software installs in 10 seconds, SQLServer in 1 hour. Firebird installation is much easier. 2) SQLSERVER runs on windows server only 3) My customers have all the express edition 4) i am not using any advanced feature, I am now starting using filestream, but the main reason for this is that Express eidtion has 4/10GB db size limit So these are all Pros of moving to Firebird. Which are the cons? I can also plan to support both platiforms, but this will backfire I fear.

• CAD/CAM without C++

  - by zaladane

  Hello, Is it possible to do CAD/CAM software without having to use C++? My company developed their software with c/C++ but that was more than 10 years ago. Today,there is a lot of legacy code that switching would force us to get rid of but i was wondering what the actual risks are. We have a lot of mathematical algorithms for toolpath calculations, feature recognition and simulation and 3D Rendering and i was wondering if C# can handles all of that without great performance loss. Is it a utopia to rewrite such algorithms in c# or should that language only deal with UI. We are not talking about game development here (Halo 3 or Call Of Duty) so how much processing does CAD/CAM really need? Can anybody enlighten me on this matter? Most of my colleagues are hardcore C++ programmers and although i program in c++ i love .NET but i am having a hard time selling .NET to them other than basic UI. Does it make sense to consider switching to .NET in such a field, or is it just not a wise idea? Thank you

• What technology to use for a RIA

  - by user297159

  I have to develop a online business software solution (similar to ERP) for a company to manage the information exchange for internal use and with external partners. It should be online. What technology should I use, I have checked framewroks like: Flex, Silverlight, Google/GWT, sencha (ExtJS), jQuery, DoJo, Telereik, Infrajistics and others similar. But they seam to be very low level programming. May be this is advantage for other projects, where you need more flexibility, but this project is stright forward. I need something more focused on business software (tables, forms, processes) where and eventually more efficient with less coding, or something I can save time. Is force.com an option? But I can not install this on the customer's servers... Do you have any ideas for me for a web based framework focused on business applications?
