• Whay types of grammar files are usable for spoken voice recognition?

  - by user1413199

  I'm using the System.Speech library in C# and I would like to create a smaller file to house commands as opposed to the default grammar. I'm not totally sure what I need. I've been looking at several different things but I don't really have any idea what I'm doing. I've read up on some stuff in ANTLR and looked at NuGram from NuEcho. I understand what a grammar file is and roughly how to create one but I'm not sure how they're used specifically for deciphering spoken words.

• Tool to maintain a Data Mapping between two systems

  - by ktaylorjohn

  We have XML interfaces between multiple systems. An Enterprise Domain Model is missing in the overall architecture, hence the terms Product/Customer/User means different things to different systems. We currently use excel sheets to map the elements in incoming XML to what the actual Field means within our system. Additionally, it contains the values of Mandatory/Optional and length of each field. We call this the Data Dictionary. Any changes to the XML go through rounds of deliberation and updates to Word and Excel documents. Is there a better way to do this? Any tool/GUI based approach which all systems and owners can view?

• Styled Javascript Popup that Connects to Database

  - by user269799

  I want to create a javascript popup box that contains text fields. I want to be able to style this box - using CSS - and I want the textfield entries to be Inserted into a MySQL database. Is this possible? I would be familiar with doing this through web forms and server side scripting but I need it to be a bit more client side this time to make things seem a bit faster. I am thinking I may need to learn some AJAX but any pointers would be a help. GF

• Maintaining traceability up-to-date as project evolves

  - by Catalin Piti?

  During various projects, I needed to make sure that the use case model I developed during the analysis phase is covering the requirements of the project. For that, I was able to have some degree of traceability between requirement statements (uniquely identified) and use cases (also uniquely identified). In some cases, enabling traceability implied some additional effort that I considered (and later proved) to be a good investment. Now, the biggest problem I faced was to maintain this traceability later, when things started to change (as a result of change requests, or as a result of use case changes). Any ideas of best practices for traceability maintenance? (It can apply to other items in the project - e.g. use cases and test cases, or requirements and acceptance test cases) Later edit Tools might help, but they can't detect gaps or errors in traceability. Navigation... maybe, but no warranty that the traceability is up-to-date or correct after applying the changes.

• SQL 2008 table locked - can't work out why

  - by Mr. Flibble

  I have two databases on one SQL 2008 server. Database 1 seems to be causing a lock on a table on database 2. There no queries are running on database 1 that should affect database 2. Is this normal behaviour? When I view the running queries with this command SELECT sqltext.TEXT, req.session_id, req.status, req.command, req.cpu_time, req.total_elapsed_time/1000 [seconds] FROM sys.dm_exec_requests req CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS sqltext it tells me as much, and says that the command on database 2 is suspended. I'm at a bit of a loss. What sort of things should I look at to work out why the table in database 2 is locked?

• If I had to create a server farm what should I do? (how others companies work?)

  - by Michel

  I have a business idea but this is not really my field so I'm trying to understand what I'm really dealing with. I have a general understanding of how a web farm works, I'm a web developer and I understand the technology behind it, but I'm curious to know specifically how a web farm is set up and which professionals are involved. Things to consider probably are the hardware, the power supply, the software managment, the cooling system and if possible the usage of green technology/power recycling. Basically, can you explain me how a web hosting company is structured and how it works? A big question, I know, but from what I already read here about the subject a lot of you know this stuff. Thanks for your time guys!

• Parent/Child forms communication issue

  - by user361583

  Hi, I am very new to Visual C++ programming, but I have to write simple program which needs to do two things: ( I am using MS Visual C++ ) main ( parent ) form should be displayed when program starts, and after clicking a button on it, second form should be shown. Second form ( child ) also has a button, but this one should ( after clicking, of course ) show current X,Y child form position but on ( important ): parent form. And this is where i got stuck. I can display child form with: a) adding #include "child.h" in parent form.h b) adding child ^child_form; in public: section and afterwards using: child_form = gcnew child(); child_form-Show(); I was googling for two days now and cannot find a way to get it the other way: click on a button on child_form and display it's coordinates on parent form on label-text :/ when i tried to add #include "child.h" in child_form I just got error saying: "there are to many include files..." I really need to get this done and I would really appreciate any suggestions. Thanks in advance :)

• How can I get a Dialog style activity window to fill the screen?

  - by Matthias

  I am using an activity with the dialog theme set, and I want it to be full screen. I tried all sorts of things, even going through the WindowManager to expand the window to full width and height manually, but nothing works. Apparently, a dialog window (or an activity with the dialog theme) will only expand according to its contents, but even that doesn't always work. For instance, I show a progress bar circle which has width and height set to FILL_PARENT (so does its layout container), but still, the dialog wraps around the much smaller progress bar instead of filling the screen. There must be a way of displaying something small inside a dialog window but have it expand to full screen size without its content resizing as well?

• Javascript Shift+Enter (Firefox)

  - by Stephen MCGinley

  Hi guys, Had a look and found some things on this, but nothing seems to work as I'd like it. Initially I had my solution working with internet explorer and chrome, but not firefox (which is unsatisfactory for me to not have working) What I'm looking for is a simple text area, which sends data on enter key, but creates a new line on Shift+Enter. The following is what I have function goReturn(e,str) { var e = (window.Event) ? e.which : e.keyCode; if (e.shiftKey && e=="13") { document.getElementById("wall").value = document.getElementById("wall").value+"\n"; } else if(e=="13"){ // ...continue to send data } } This sends the data on enter, but also sends the data on shift and enter (which is the problem I have). Thanks for any assistance

• How do I create custom Controls for my VS2005 toolbox?

  - by end-user

  Ok, this question might more about design theory. I have successfully created controls that show up in my toolbox, so I'm pretty sure I have the process right. Also, my "AutoToolboxPopulate" is set to true, so things are showing up as I create them. My question is this: I'm sub-classing a native Control for specialized use. When I derive my class from an exposed concrete class, such as BulletedList, my custom Control appears in my Toolbox. However, when I drop it back to the parent, such as ListControl, my Control is not listed (actually it's grayed out when I "List All"). What am I missing?

• How can I generate an RFC1123 Date string, from C code (Win32)

  - by Cheeso

  RFC1123 defines a number of things, among them, the format of Dates to be used in internet protocols. HTTP (RFC2616) specifies that date formats must be generated in conformance with RFC1123. It looks like this: Date: Wed, 28 Apr 2010 02:31:05 GMT How can I generate an RFC1123 time string from C code, running on Windows? I don't have the use of C# and DateTime.ToString(). I know I could write the code myself, to emit timezones and day abbreviations, but I'm hoping this already exists in the Windows API. Thanks.

• Self-contained python installation with executable tools included (pip, orbited, etc)

  - by Tristan

  I'm trying deploy a Python application on Windows as a folder that includes a full python 2.6 folder. I don't need/want a fancy solution like py2exe, I'm just trying to automate deployment of a web application. So long as I include python26.dll and set the PYTHONHOME correctly, things seem to work if I just include the Python26 folder in its entirety. However a number of the Python26/Script files don't work. For instance, pip.exe, orbited.exe, and morbid.exe all do nothing (complete with no output) when I try to run them on a system that doesn't have a real Python26 installation. I've run out of ideas. Suggestions?

• Make backup of large site with 100,000+ files/images

  - by niggles

  I tried backing up our site today using the Unix 'cp' command and ended up getting our office blocked out by PLESK - it added my ip to /etc/hosts.deny as it thought I was flooding the server. After Tech support fixed the issue, they suggested I go folder by folder to back it up, but there's about 10,000 folders on the site totaling 1/2 a terabyte, each with multiple sub-folders, so this isn't viable. Basically I want to be able to mirror the domain on another domain we've got set up on the same dedicated server so I can test with live images (the bulk of our content). Any suggestions e.g adding some rules to open_base_dir and getting PHP to recursively copy the folders to the other domain (remember it's on the same dedicated box so it just needs to traverse the directory, not FTP things).

• How do you create a daemon in Python?

  - by DavidM

  Searching on Google reveals x2 code snippets. The first result is to this code recipe which has a lot of documentation and explanation, along with some useful discussion underneath. However, another code sample, whilst not containing so much documentation, includes sample code for passing commands such as start, stop and restart. It also creates a PID file which can be handy for checking if the daemon is already running etc. These samples both explain how to create the daemon. Are there any additional things that need to be considered? Is one sample better than the other, and why?

• Dynamic creation of a pointer function in c++

  - by Liberalkid

  I was working on my advanced calculus homework today and we're doing some iteration methods along the lines of newton's method to find solutions to things like x^2=2. It got me thinking that I could write a function that would take two function pointers, one to the function itself and one to the derivative and automate the process. This wouldn't be too challenging, then I started thinking could I have the user input a function and parse that input (yes I can do that). But can I then dynamically create a pointer to a one-variable function in c++. For instance if x^2+x, can I make a function double function(double x){ return x*x+x;} during run-time. Is this remotely feasible, or is it along the lines of self-modifying code?

• "Automatic" class proxy in C++

  - by PierreBdR

  I need to allow the user to change members of two data structures of the same type at the same time. For example: struct Foo { int a, b; } Foo a1 = {1,2}, a2 = {3,4}; dual(a1,a2)->a = 5; // Now a1 = {5,2} and a2 = {5,2} I have a class that works and that change first a1 and then copy a1 into a2. This is fine as long as: the class copied is small the user doesn't mind about everything being copied, not only the part modified. Is there a way to obtain this behavior: dual(a1,a2)->a = 5; // Now a1 = {5,2} and a2 = {5,4} I am opened to alternative syntax, but they should stay simple, and I would like to avoid things like: set_members(a1, a2, &Foo::a, 5); members(a1, a2, &Foo::a) = 5; or anything involving specifying explictely &Foo::

• CUDA Global Memory, Where is it?

  - by gamerx

  I understand that in CUDA's memory hierachy, we have things like shared memory, texture memory, constant memory, registers and of course the global memory which we allocate using cudaMalloc(). I've been searching through whatever documentations I can find but I have yet to come across any that explicitly explains what is the global memory. I believe that the global memory allocated is on the GDDR of graphics card itself and not the RAM that is shared with the CPU since one of the documentations did state that the pointer cannot be dereferenced by the host side. Am I right?

• Merge array in a different way in PHP

  - by user2984974

  I have these two arrays: $array1 = array( '0' => 'apple', '1' => '' , '2' => 'cucumber' ); $array2 = array( '0' => '', '1' => 'bmw', '2' => 'chrysler' ); if I do this to merge these arrays: $result_arr = array_merge($array1, $array2); print_r( count ( array_filter($result_arr) ) ); the output would be 4. However, I need to get the number 3. So, when there are two things on the same position (same key) count it only once. Is it possible to merge/count elements in arrays like that?

• What is a Custom Class?

  - by John Saunders

  Many questions here on SO ask about custom classes. I, on the other hand, have no idea what they're talking about. "Custom class" seems to mean the same thing I mean when I say "class". What did I miss, back in the '80s, that keeps me from understanding? I know that it's possible to purchase a packaged system - for Accounting, ERP, or something like that. You can then customize it, or add "custom code" to make the package do things that are specific to your business. But that doesn't describe the process used in writing a .NET program. In this case, the entire purpose of the .NET Framework is to allow us to write our own code. There is nothing useful out of the box.

• Portable Socket programming in C/C++ possible?

  - by questions

  I am thinking of creating a multi-platform portable C++ server-client application. Is it even possible while using only standard libraries? If no, what other libraries are there? Are there any improvements in this direction in C++11x? Like for threads, now we have std::threads. To make it more clear.. I want something like boost::thread, which provides multiplatform portable multithreading, for networking. And why C++ doesn't have libraries(standard) for such basic things like networking?

• How do you keep Cocoa controllers from getting too big?

  - by zoul

  Hello! Do you have some tricks or techniques to break Cocoa controller classes into smaller chunks? I find that whatever I do the controllers end up being one of the more complicated classes in my design. The basic stuff is simple, but once I have several pop-overs or action sheets running, things get uncomfortably complex. It's not that bad, but still I would like to refactor the code into several standalone chunks. I thought about categories, but the code is not that independent (a lot of times it needs to tap into viewWillAppear, for example) and I find that I spend a long time fighting the compiler. I also thought about adding functionality in layers using inheritance, but that feels like a hack.

• Dealbreakers for new programming jobs?

  - by Echostorm

  What might be said or implied at an interview or job posting that should set off alarm bells for a coder? I'm still only a few years in the industry but I already know to look out for excessive red tape and bureaucracy. Cubes and a noisy office also tell me that I'll be both miserable and unproductive and that management does not appreciate what coders need to work well. Edit: The way things are going I'm taking extra time to look at the company's stability. If they depend on a single vendor for their livelihood and could be out of business if the vendor decides they don't really need the service or can do it in-house. What are your dealbreakers?

• Content cacheing with PHP and CodeIgniter

  - by Josh K

  I have a couple of things I'm working on, namely a page that issues five or six cURL requests and processing content on them. I'm working with CodeIgniter on a LAMP stack but am open to other options. Naturally I would prefer to not rewrite the application. I would like to know if there are any ready-made / easily learned caching methods. Primarily I'd like to check if the page has changed since I last scrapped it. If it has, redownload and present. If it hasn't, serve up a cached copy.

• ExtJS (4.0) dynamic / lazy loading

  - by Paul

  Given a border layout with a west (navigation) and a center region. Let say I click on topic A in the west region, I want to replace (replace as in 'delete last topic') the center region with 'extjs' program code named topic_a.js I succeed in loading with this code: dynamicPanel = new Ext.Component({ loader: { url: '/www/file.htm', renderer: 'html', autoLoad: true, scripts: true } }); var oMainContainer = Ext.getCmp('maincontainer'); oMainContainer.show(); oMainContainer.add(dynamicPanel); But calling this the second time 'adds' things up in the center region and of course fails short in 'deleting', what would be a good approach?
