• One off errors with NSLog and NSString stringWithFormat

  - by David Liu

  Does anyone know why there would be one-off errors with NSLog and NSString? It works fine in 99% of my program, but for some reason this error appears in one of my model's description method: Example code: localFileId = 7; type = 2; localId = 5; NSLog(@"CachedFile localId=%d, 2=%d, localFileId=%d, type=%d, path=%@", localId, 2, localFileId, type, self.path); Example Result: CachedFile localId=5, 2=0, localFileId=2, type=7, path=(null) Notice the "0" that gets inserted in there, where it should be "2=2". This happens with NSString stringWithFormat as well.

• How do I use the Silicon Laboratories IDE with SDCC?

  - by David Cary

  I'm thinking about using a microcontroller with an 8051 core from Silicon Laboratories. I hope that I can use C rather than assembly language, so I installed SDCC. I installed the "Silicon Laboratories IDE" to download the executable binaries to the on-chip Flash program memory. It also supposedly can be set up (under the Project Tool Chain Integration menu) to use "any" 8051 compiler. I tried to set it up to use SDCC, but every time I hit the "Assemble/Compile File" button it tells me "Compiler process did not sucessfully complete." How do I get new C code I write onto the SiLabs C8051F310 chip? Is there a web site with a step-by-step HOWTO? (Would it be easier to use a MAKEFILE that calls SDCC, only using the "Silicon Laboratories IDE" for the very last step of downloading the executable binary to the chip?)

• Need to get back form controls' information externally

  - by Tom

  Are there any tutorials or guides out there that anyone knows of that will show me how to read forms from an external program and get back information about the controls on the form? Currently, I can get the handle to the form, and I can get the class name, but I need to get more information such as a persistent name and contained data. Thanks. Edit: I now have a way to read the contained data (with the WM_GETTEXT message), however, I still need a persistent name/ID that I can be sure will not change from instance to instance. One way I can think of for doing this is to take the handle, find the position of the control on the window, and then get the handle from the position from then on. Another way is to determine a static ID for the control and then use that to get the handle from then on. The new scope of my problem is how to implement either of these. Any Ideas?

• Create mp3 previews from wav and aiff files

  - by August Lilleaas

  I would like to create a program that makes mp3s of the first 30 seconds of an aiff or wav file. I would also like to be able to choose location and length, such as the audio between 2:12 and 2:42. Are there any tools that lets me do this? Shelling out is OK. The application will run on a linux server, so it would have to be a tool that works on linux. I don't mind doing it in two steps - i.e. a tool that first creates the cutout of the aiff/wav, then pass it to a mp3 encoder.

• iPhone+Quartz+OpenGL. What is the correct way for Quartz and OpenGL to play nice together regarding

  - by dugla

  So we know the CoreGraphics/Quartz imaging model is based on pre-multiplied alpha. We also know that OpenGL blending is based on un-premultiplied alpha. What is the best practice to avoid head explosion when doing blending with textures that are derived from pre-multiplied alpha imagery (PNG files generated in Photoshop with pre-multiplied alpha). Given the apples/oranges mish mash of Quartz and OpenGL, what is the correct glBlendFunc for doing the fundamental Porter/Duff "over" operation? Typical example: A simple paint program. Brush shapes are texture-map patterns created from pre-multiplied alpha rgba images. Paint color is specified via glColor4(...) with the alpha channel used to control paint transparency. GL_MODULATE is used so the brush texture multiplies the (translucent) paint color to blend the color into the canvas. Problem: The texture is premult. The color is not. What is the correct way to handle this fundamental inconsistency? Thanks, Doug

• How can Perl interact with an ajax form

  - by Jeff

  I'm writing a perl program that was doing a simple get command to retrieve results and process them. But the site has been updated and now has a java component that handles the results (so the actual data is not in the source code anymore). This is the site: http://wro.westchesterclerk.com/legalsearch.aspx Try putting in: Index Number: 11103 Year: 2009 I want to be able to pro grammatically enter the "index number" and "year" at the bottom of the form where it says "search by number" and then retrieve the results listed next to it. I've written many programs in Perl that simply pass variables via the URL and the results are listed in the source code, so it's easy to parse. (Using LWP:Simple) Like: $html = get("http://www.url.com?id=$somenum&year=$someyear") But this is totally new to me and I don't know where to begin. I'm somewhat familiar with LWP:UserAgent and Mechanize. I'd really appreciate any help. Thanks!

• Modbus driver: C vs Java

  - by cpf

  Hi stackoverflow, I am soon going to start a project where I'm required to program a Modbus driver. My initial approach was to want to do it in Java, however my boss has had contact with a company that has experience in Modbus, and they said C is the better language to approach Modbus. So my boss pretty much demanded it to be in C. My C knowledge is not really big, so it would require me to learn enough to get the Modbus driver working in proper and stable order. So, my question to you stackoverflow people with some experience in Modbus: how important could the choice of C vs Java be? The modbus site seems to have Java libraries, if C was so superior to Java in every way, why would they have those libraries? Would it be useful to learn C properly for the advantages that might give?

• VB.net Edit-And-Continue: ignore "unable to apply this change while debugging"

  - by FastAl

  When using VB.Net (2008) and paused in debugging, Edit-And-Continue is a great time-saver. However if you change any module/class-level information (variable, sub/function signature, etc), you get the error message like this: "unable to apply this change while debugging" While I can understand the technical challenge to making this work (and why it would be hard), it leaves me in a tight spot with just a few options: 1) Restart and recompile and get the program back to the same state 2) Continue debugging without making the change, and risk forgetting 3) Type up a reminder note to make the change All of which are annoying. Now I know that option '4) Just actually make the change' may not be possible. but does anybody know how to enable the following 'technically easy' possibility? 4) Let me change the code, get it flagged with the purple squiggly underline, so I can save it, but just ignore the change until recompile I have checked the Tools|options|debug|edit and continue, nothing appears to let me do this. thanks!

• inserting std::strings in to a std::map

  - by PaulH

  I have a program that reads data from a file line-by-line. I would like to copy some substring of that line in to a map as below: std::map< DWORD, std::string > my_map; DWORD index; // populated with some data char buffer[ 1024 ]; // populated with some data char* element_begin; // points to some location in buffer char* element_end; // points to some location in buffer > element_begin my_map.insert( std::make_pair( index, std::string( element_begin, element_end ) ) ); This std::map<>::insert() operation takes a long time (It doubles the file parsing time). Is there a way to make this a less expensive operation? Thanks, PaulH

• code to edit the text in an EditText widgit

  - by user293663

  Hello, I am a newbi programmer and am having trouble with a measurement conversion program I am working on. What I would like to do is have several EditText boxes. When one is filled in and a calculate button is hit then the rest will be populated with a converted number. The part I am getting stuck on is outputting the answers to EditText widgets. ex: There are three EditText Widgets. a user inputs the number 6 into the first one (labeled inches) and presses calculate. I would like the next box to display .5 (labeled feet) and the last to display .1666 (this would be yards) .setText() apparently does not work to modify the text in an EditText any help would be greatly appreciated.

• Wanted: Command line HTML5 beautifier

  - by blinry

  Wanted A command line HTML5 beautifier running under Linux. Input Garbled, ugly HTML5 code. Possibly the result of multiple templates. You don't love it, it doesn't love you. Output Pure beauty. The code is nicely indented, has enough line breaks, cares for it's whitespace. Rather than viewing it in a webbrowser, you would like to display the code on your website directly. Suspects tidy does too much (heck, it alters my doctype!), and it doesn't work well with HTML5. Maybe there is a way to make it cooperate and not alter anything? vim does too little. It only indents. I want the program to add and remove line breaks, and to play with the whitespace inside of tags. DEAD OR ALIVE!

• C#: How do I get the path of the assembly the code is in?

  - by George Mauer

  Is there a way to get the path for the assembly in which the current code resides? I do not want the path of the calling assembly, just the one containing the code. Basically my unit test needs to read some xml test files which are located relative to the dll. I want the path to always resolve correctly regardless of whether the testing dll is run from TestDriven.NET, the MbUnit GUI or something else. Edit: People seem to be misunderstanding what I'm asking. My test library is located in say c:\projects\myapplication\daotests\bin\Debug\daotests.dll and I would like to get the "*c:\projects\myapplication\daotests\bin\Debug*" path. The three suggestions so far fail me when I run from the MbUnit Gui: Console.Out.Write(Environment.CurrentDirectory) gives c:\Program Files\MbUnit Console.Out.Write(System.Reflection.Assembly.GetAssembly(typeof(DaoTests)).Location) gives C:\Documents and Settings\george\Local Settings\Temp\ ....\DaoTests.dll Console.Out.Write(System.Reflection.Assembly.GetExecutingAssembly().Location) gives the same as the previous

• How to view Mercurial changeset changes using a GUI diff tool

  - by Marcus

  We use both Examdiff and Kdiff3 to view Mercurial changes. Just add this to .hgrc: [extdiff] cmd.kdiff3 = cmd.examdiff = C:\Program Files\ExamDiff Pro\ExamDiff.exe And then you can type hg examdiff or hg diff3 to see a complete diff of all your changes. What I would like is to do the same to see a "before and after" of files for a given changeset that was checked in by someone else. I know you can type hg log to see all changesets and then hg log -vprXX to see a text diff, but that's too hard for my GUI preferring eyes. Anyone know how to the equivalent with the GUI tools?

• Imitate database in C

  - by Mohit Deshpande

  I am fairly new to C. (I have good knowledge of C# [Visual Studio] and Java [Eclipse]) I want to make a program that stores information. My first instinct was to use a database like SQL Server. But I don't think that it is compatible with C. So now I have two options: Create a struct (also typedef) containing the data types. Find a way to integrate SQLite through a C header file Which option do you think is best? Or do you have another option? I am kind of leaning toward making a struct with a typedef, but could be pursuaded to change my mind.

• problem with closing sockets

  - by Samantha

  Hi, I'm trying to write a client/server program with threads. I close the socket once the connexion is finished. The servers gets plenty of new connexions, and the socket number (file descriptor) increases very quickly: after 5 minutes running I was already at around file descriptor number 800! Is this a normal thing? Do threads share file descriptors? When I do close(sockfd); is the number released immediatly or after a some time? PS: I used to do with fork(), and I didn't have this issue. Thanks

• form not showing

  - by Luke

  Perhaps this has something to do with it being the mainForm, but I'll ask the question. I have my mainForm that is the first to load when the program is booted. I then click a button called Add, which should open a new form, and close the mainForm. The problem is, is shows the new form for a split second, then closes both. The code: private void addFrmBtn_Click(object sender, EventArgs e) { saveForm saveform = new saveForm(); saveform.Show(); this.Close(); }

• Good articles to read on SSL and HTTPS?

  - by Igor Romanov

  I had a problem with accepting invalid SSL certificate in my iPhone program. That problem is solved now, however I came to understanding that I have very abstract idea on how exactly the whole thing is working: how web browser is verifying that received certificate is really for host it communicates to and not faked by same party in the middle? if browser talks to some 3rd party (CA?) to do certificate check? and many other questions... Would someone please recommend good source of information with in-depth enough description of how all parts click together?

• alias_attribute and creating and method with the original attribute name causes a loop

  - by Tiago

  Im trying to dynamically create a method chain in one attribute in my model. By now I have this function: def create_filtered_attribute(attribute_name) alias_attribute "#{attribute_name}_without_filter", attribute_name define_method "#{attribute_name}" do filter_words(self.send("#{attribute_name}_without_filter")) end end so I receive a string with the attribute name, alias it for '*_without_filter*' (alias_method or alias_method_chain fails here, because the attribute isnt there when the class is created), and I create a new method with the attribute name, where I filter its contents. But somehow, when I call *"#{attribute_name}_without_filter"* it calls my new method (i think because the alias_attribute some how), and the program goes into a stack loop. Can someone please enlighten me on this.

• Howto troubleshoot vb6 dll 800a01ad error in c# application

  - by phq

  I have a dll that I created from a VB6 project that I am now using in a c# project. This has worked before but now when I try to return to the c# project to fix a bug, the program get a COMException stating roughly translated: Could not create an instance of COM-component with CLSID {085E3494-9F78-47D5-B0E6-FA460FD3CBED} from IClassFactory because of the following error: 800a01ad. So I try to create a new empty c# project with only one line in the main function: OurNamespace.OurClass foo = new OurNamespace.OurClass(); Which fails with the same error. I have registered the dll but that did not change the outcome of the problem. The problem only occurs on the machine I am currently at, still I'm interested to understand the problem so that I know how to fix it if it occurs on a customers computer.

• Is there a utility that will let me write to an Excel 2007 .xlsm file with macros enabled?

  - by Mike Webb

  I am writing a program that writes to Excel files. I am restricted to writing to Excel 2007, which is fine, and I'm using EPPlus, which is a great utility. The thing is that I need to have macros and VBA enabled for an update function in the sheet, but EPPlus will only write to .xlsx files, not macro-enabled .xlsm files. If I try to write to .xlsm files it won't open. Is there another code library that lets me accomplish what I need (again that's writing to Excell 2007 Macro-enabled workbooks)?

• Programming on Leopard for iPhone OS 3.1.3

  - by Blank6

  Hey, I got Leopard with XCode 3.1 and SDK 3.0, when opening the organizer and trying to debug on my ipod I received "The version of iPhone OS on "..." does not match any of the versions of iPhone OS supported for development with this copy of xCode...". It tells me with my xCode I can only develop for iPhone OS 3.0 or less, so I downloaded the new xCode + SDK installation bundle, knowing the SDK can't be installed on Leopard. In the installation it tells me "If you don't want to install the SDK, press disagree", and so I did, but in the next screen he forces me to choose a drive for the SDK, and then says "you can't install the SDK on leopard system", and I can't pass this screen. My question is: is it even possible to program on Leopard for iPhone OS 3.1.3? I really want to debug my apps on my iPod (framework 3.1.3, 3G) Thanks ahead!! By the way: I can't so simply upgrade to snow leopard because it's a hackintosh, so I prefer a different way..

• "Arbitrary" context free grammars?

  - by danwroy

  Long time admirer first time inquirer :) I'm working on a program which derives a deterministic finite-state automata from a context-free grammar, and the paper I have been assigned which explains how to do this keeps referring to "arbitrary probabilistic context-free grammars" but never defines the meaning of "arbitrary" in relation to PCFGs. I assume they mean "any old PCFG" but then why not just say "any PCFG"? The term also turns up in several Wikipedia entries. At the top of the CFG page there is a reference to arbitrariness in relation to CFGs on ("clauses can be nested inside clauses arbitrarily deeply"), but doesn't make clear why someone would refer to a PCFG or subset of PCFGs as arbitrary. In case anyone is curious, the paper is Parsing and Hypergraphs by Klein and Manning (2001); I've also been reading two other papers by them related to this one (An Agenda-Based Chart Parser for Arbitrary Probabilistic Context-Free Grammars and Empirical Bounds, Theoretical Models, and the Penn Treebank) which use the term extensively but never explain it either. Thanks for your help!
