• Feasability of reverse engineering some embedded code

  - by user258526

  All, My company is in the situation where we are using an embedded control system from another company in another country. We do not have the source code or the schematics to this system, and the manufacturer doesn't want to release them, seemingly at any price or under any terms. We are thus stuck with a 6 month turn around to get even a small modification done, and they can basically charge any amount they want. Legal aspects aside, would it be at all feasible to reverse engineer the embedded code back into C? Do any companies exist that could do this for us? Thank you, Fred

• How to reference THE UIWindow from sub UIViewControllers?

  - by maralbjo

  I am trying to add another subview programmatically based on some event (user taps a button, for instance). My problem is that I am having problems referencing the (one and only) instance of UIWindow. I reach it from my appDelegate, because the MainWindow.xib and the appDelegate have been wired up. But I cannot reach the UIWIndow from anywhere else (I cannot draw that connection in IB, can I?) What techniwue is preferred to get a reference to (the one and only) UIWindow? ...so that I in turn can use the following code from my various UIViewControllers: [myOneAndOnlyWindow addSubview:oneOfManyViews.view]; [myOneAndOnlyWindow makeKeyAndVisible];

• Lua: Why changing value on one variable changes value on an other one too?

  - by user474563

  I think that running this code you will get excactly what I mean. I want to register 5 names to a register(people). I loop 5 times and in each loop I have a variable newPerson which is supposed to save all information about a person and then be added to the people register. In this example only the names of the people are being registered for simplicity. The problem is that in the end all people turn to have the same name: "Petra". I playied a bit with this but can't get a reasonable reason for this behaviour. Help appreciated! local people={} local person={ name="Johan", lastName="Seferidis", class="B" } local names={"Markus", "Eva", "Nikol", "Adam", "Petra"} --people to register for i=1, 5 do --register 5 people local newPerson=person local name=names[i] for field=1, 3 do --for each field(name, lastname, class) if field==1 then newPerson["name"]=name end --register name end people[i]=newPerson end print("First person name: " ..people[1]["name"]) print("Second person name: "..people[2]["name"]) print("Third person name: " ..people[3]["name"])

• Separating null byte separated UNICODE C string.

  - by Ramblingwood

  First off, this is NOT a duplicate of: http://stackoverflow.com/questions/1911053/turn-a-c-string-with-null-bytes-into-a-char-array , because the given answer doesn't work when the char *'s are Unicode. I think the problem is that because I am trying to use Unicode and thus wchar_t instead of char, the length of each character is different and thus, this doesn't work (it does in non-unicode): char *Buffer; // your null-separated strings char *Current; // Pointer to the current string // [...] for (Current = Buffer; *Current; Current += strlen(Current) + 1) printf("GetOpenFileName returned: %s\n", Current); Does anyone have a similar solution that works on Unicode strings? I have been banging my head on the this for over 4 hours now. C doesn't agree with me.

• 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 can i get notifications from server to android device?

  - by Vaibs

  I am creating a app wherein user shares some information. This data i am storing it in database through servlets i.e. i am calling my own servlets which will take data through url and store it in database. So i want other users of that same app to get notify that some information is available and in turn they will get the information that other user has updated. For this to work we can use polling or pusher. But polling will take lots of battery power. I have tried C2DM but its not working for me. So i am thinking for some other mechanism by which i can implement other than C2DM. Please suggest some way to work it. and e.g. if u have came across.

• How to prevent Spell checking code in MS Office?

  - by Aaron

  We use MS Office. Outlook for emails, Word for some documentation and I use OneNote a lot for my own note taking. What bugs me is when I drop some code or use key words or even camel case into these apps the spell checking picks them up and I have red squiggles everywhere. Ignore is pretty much useless, so either I have to turn off Spell Check altogether start adding these to the custom dictionary. What would be good is if I can use the Set Language function to mark a whole block of text to just not be spell checked. Has anyone found a nice solution to this or do you know of a blank dictionary is best to use? I found using "Mohawk" kind of does that... might just use that for now. Maybe create a macro to switch between them.

• FOR XML PATH Query results to file with SSIS

  - by whimsql

  In SSMS I've gotten my for xml path query written and it's beautiful. I put it in an "Execute SQL Task" in the Control Flow, set the resultset to XML. Now how to I get the results into an actual xml file that I can turn around and FTP to a third party? This should have been so easy! I would put the XML into a variable but we are looking at a HUGE file, possibly 100mb+ Do I need to use a Script Task? (I'd like to avoid that if there is another option.)

• Browser popup blocker blocking jasper reports generated from flex

  - by pietervn

  Hi all, I have a flex application that uses navigateToURL() to call a servlet. The servlet in turn generates a JasperReport and then uses exportReport() to show the report in a new browser tab. Now, my problem is this. I want to generate multiple reports at once, each opening in its own tab. It all works fine except that in Firefox the built in browser pop-up blocker sees every new tab that is opened after the first report tab as a pop-up. It blocks this and is giving me endless headaches. I also tried this in IE8, Safari, Chrome and Opera with no problems. Any help as to how I can get past the Firefox pop-up blocker would be much appreciated. Pieter

• Is there a visual guide to the UIKit components?

  - by Tim Büthe

  My Problem is this, I want to add some component to my App I saw in some other App. Everytime I wnat to do this, I start googling around for the name. It took me some time to find the name of UIActionSheet. Now I'm looking for that transparent overlay that appears when you turn the volume up and down. So, is there a good visual guide to the UIKit components? As an example, see the visual guide to swing components or this visual guide which is way to short/incomplete. And secondly, what's the name of the component I'm looking for?

• asp.net mvc custom routes with multiple submit buttons

  - by dangerisgo

  So I have a custom route as such: routes.MapRoute( "Wizard", // Route name "Wizard/{page}", // URL with parameters new { controller = "Wizard", action = "Index" } // Parameter defaults ); and have the following on my View: <% Html.BeginForm("Continue", "Wizard"); %> <input type="submit" value="Continue" name="Continue" /> <% Html.EndForm(); %> In which I want to call this function: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Continue(string Number, string Rev) { (...) } but in turn when that button is pressed always calls the postback Index rather than the one I want. If I remove the custom route, it calls my function, but what I want to be displayed in the address bar is: localhost:xxxx/Wizard/1 where the number at the end is the page (div shown) of the wizard either 1, 2, 3, or 4. So is there something I'm missing or can it not be done? Thanks.

• slowly rotate an object towards another object

  - by numerical25

  I have an object that points in the direction of another object (i.e. it rotates to the direction that the second objects x and y coordinates are at) below is the code I use. var distx = target.x - x; var disty = target.y - y; var angle:Number = Math.atan2(disty, distx); var vx:Number = Math.cos(angle) * cspeed; var vy:Number = Math.sin(angle) * cspeed; rotation = angle * 180/Math.PI; x += vx; y += vy; as you can see. Not only does it rotate towards the target object, but it also moves towards it too. When I play the movie, the object instantly points to the targeted object and moves towards it. I would like for it to slowly turn towards the object instead of instantly turning towards it. anyone know how to do this.

• How to determine what invokes User Access Control restrictions?

  - by MX4399

  In a Delphi app intended to build an internet software update service for my software, the Windows 7 UAC system requests authorization from the user to run the exe.The following possible contentious/risk areas exist in the code: A named pipe server is created for communications TCP is used for FTP and HTTP SHGetSpecialFolderPath api call is used Before these items where added UAC did not activate, removing each in turn including all unit reference and then ending with the bare bones exe still causes the UAC event - so its not possible say what is causing it. On top of this Delphi 2007 now requires being launced as an administrator to launcg a debugging process for the app. Question 1 : How can I see what is causing this besides starting from scratch in a new exe - IOW is there a log somewhere I can check Question 2 : Will using a signed exe using authenticode still cause the UAC alert to show

• Make Sphinx generate me rst for class documentation from pydoc

  - by Michal Cihar

  I'm currently in process of migrating existing (non complete) documentation to Sphinx. The final goal is to have all documentation in Sphinx. The problem I'm facing right now is that I have some documentation using Python docstrings (well the module is actually written in C, but it probably does not matter) and I would like to generate class documentation in form usable for Sphinx from these docstrings. I know there is sphinx.ext.autodoc, but it automatically puts current docstrings to the document. I rather want to generate source (rst) file based on current docstrings, which I could edit and improve manually. So is there some way to turn existing docstrings into rst form which Sphinx consumes?

• Is it possible to take a screenshot of a web page with Javascript or HTML5/Canvas?

  - by Ryan Kearney

  Is there a way I could insert some code into a page that would take a screenshot of what the user sees in the browser window, then upload that image via a web form of some sort? I'm working on a clone of a pay-to-use service that lets you install a widget on a web page which in turn allows viewers to report bugs in the sites layout. Currently they use a Java applet to take the screenshot, which, in my opinion, is probably the worst way to go about it (aside from requiring the user to install a plugin) Is there a javascript/flash/other alternative? Thanks

• Flash CS5 projects panel totally gone?

  - by Jesse

  So, I popped open up Flash CS5 just now, and I couldn't find my projects panel. I was working on a dual screen set up previously, so my windows were everywhere anyways (sans external). I switched over to a smaller screen workspace, and popped opened the projects panel. Oddly enough, the code snippets panel came up instead. So, I switched off the code snippets, and tried again. I've been trying different ways of opening this panel for about 15 minutes, and I'm totally stumped. Some thorough googling didn't present any relevant results, so, StackOverflow, I turn to you. Is this a known issue? is there a secret backdoor way to open this panel? Am I totally missing something?

• C# define string format of double/floats to be US english by default

  - by neil

  Hi, I have got several thousands of lines of a web application source code, initially written on a US development system, to maintain. It makes heavy use of SQL statement strings, which are combined on the fly, e.g. string SQL = "select * from table where double_value = " + Math.Round(double_value, 2); Don't comment on bad programming style, that doesn't help me in this case :) The cruix: My system uses a German locale, which in turn leads to wrong SQL statements, like this: "select * from table where double_value = 15,5" (Note the comma as decimal separator instead of a point). Question: What is the most "elegant" way to change the locale of the web app in this case) to US or UK in order to prevent being forced to change and inspect every single line of code? .net 3.5 is not an option (would give me the chance to overwrite ToString() in an extension class) Kind regards

• Deleting rows with MySQL LEFT JOIN

  - by fabrik

  Hello! I have two tables, one for job deadlines, one for describe a job. Each job can take a status and some statuses means the jobs' deadlines must be deleted from the other table. I can easily SELECT the jobs/deadlines that meets my criteria with a LEFT JOIN: SELECT * FROM `deadline` LEFT JOIN `job` ON deadline.job_id = job.job_id WHERE `status` = 'szamlazva' OR `status` = 'szamlazhato' OR `status` = 'fizetve' OR `status` = 'szallitva' OR `status` = 'storno' (status belongs to job table not deadline) But when i'd like to delete these rows from deadline, MySQL throws an error. My query is: DELETE FROM `deadline` LEFT JOIN `job` ON deadline.job_id = job.job_id WHERE `status` = 'szamlazva' OR `status` = 'szamlazhato' OR `status` = 'fizetve' OR `status` = 'szallitva' OR `status` = 'storno' MySQL error says nothing: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'LEFT JOIN `job` ON deadline.job_id = job.job_id WHERE `status` = 'szaml' at line 1 How can i turn my SELECT into a working DELETE query? Thanks, fabrik

• Checking server load with PHP and taking appropriate action

  - by teehoo

  Hi, I'm creating a project in which a server receives operations from clients to apply to a local server document. The server and client both share the same document and therefore each message the client sends contains an MD5 hash, which the server compares to after generating its own hash to ensure the server and client documents are synchronized. My question is, if the server is overloaded, could I somehow detect this in PHP, which would in turn let me decide whether I want to execute the hash generation function or not? Perhaps in the scenario defined, this is not a perfect use-case, but I'm interested in this approach in general.

• Speeding up jQuery empty() or replaceWith() Functions When Dealing with Large DOM Elements

  - by Levi Hackwith

  Let me start off by apologizing for not giving a code snippet. The project I'm working on is proprietary and I'm afraid I can't show exactly what I'm working on. However, I'll do my best to be descriptive. Here's a breakdown of what goes on in my application: User clicks a button Server retrieves a list of images in the form of a data-table Each row in the table contains 8 data-cells that in turn each contain one hyperlink Each request by the user can contain up to 50 rows (I can change this number if need be) That means the table contains upwards of 800 individual DOM elements My analysis shows that jQuery("#dataTable").empty() and jQuery("#dataTable).replaceWith(tableCloneObject) take up 97% of my overall processing time and take on average 4 - 6 seconds to complete. I'm looking for a way to speed up either of the above mentioned jQuery functions when dealing with massive DOM elements that need to be removed / replaced. I hope my explanation helps.

• Where can I find a good book holder for decent sized programming books?

  - by Joel Marcey

  Suppose you have a book on a programming language and are trying to learn the language. You want to write the code that is given in the book in so you can learn by example while you read. But you hate holding the book on your lap and trying to type at the same time. I find that extremely uncomfortable. Someone recommended that I try using a music stand, but I figured the placement of that would be problematic since I would have to turn my head too much. Does anyone know of a good book holder that they can recommend that can sit next to your monitor so you can look at it while you type? Specifically, I am looking for one that can handle about a 600 page paperback book.

• What is a .NET managed module?

  - by Abhijeet Patel

  I know it's a Windows PE32, but I also know that the unit of deployment in .NET is an assembly which in turn has a manifest and can be made up of multiple managed modules. My questions are : 1) How would you create multiple managed modules when building a project such as a class lib or a console app etc. 2) Is there a way to specify this to the compiler(via the project properties for example) to partition your source code files into multiple managed modules. If so what is the benefit of doing so? 3)Can managed modules span assemblies? 4)Are separate file created on disk when the source code is compiled or are these created in memory and directly embedded in an assembly?

  im all new to framework. so the structure of code igniter looks like: system system/application the system folder is code igniter's base folder right? so if they in the future releases a new version i just put application in the new system folder and its upgraded right? does this mean that i shouldn't put new files and so on in the system folder? cause some code could be used for other applications and i want to put them under the current application im developing, not inside the application folder. i want my application's classes to extend my base system's classes which in turn extend code igniter's base system class. so there are 3 levels. so how could i accomplish this? where to put the system level between CI and my application?
