• bitshift large strings for encoding QR Codes

  - by icekreaman

  As an example, suppose a QR Code data stream contains 55 data words (each one byte in length) and 15 error correction words (again one byte). The data stream begins with a 12 bit header and ends with four 0 bits. So, 12 + 4 bits of header/footer and 15 bytes of error correction, leaves me 53 bytes to hold 53 alphanumeric characters. The 53 bytes of data and 15 bytes of ec are supplied in a string of length 68 (str68). The problem seems simple enough - concatenate 2 bytes of (right-shifted) header data with str68 and then left shift the entire 70 bytes by 4 bits. This is the first time in many years of programming that I have ever needed to do something like this, I am a c and bit shifting noob, so please be gentle... I have done a little investigation and so far have not been able to figure out how to bitshift 70 bytes of data; any help would be greatly appreciated. Larger QR codes can hold 2000 bytes of data...

• Java - Need help with binary/code string manipulation

  - by ShrimpCrackers

  For a project, I have to convert a binary string into (an array of) bytes and write it out to a file in binary. Say that I have a sentence converted into a code string using a huffman encoding. For example, if the sentence was: "hello" h = 00 e = 01, l = 10, o = 11 Then the string representation would be 0001101011. How would I convert that into a byte? <-- If that question doesn't make sense it's because I know little about bits/byte bitwise shifting and all that has to do with manipulating 1's and 0's.

• Javascript: Make a static code, dynamic - List of inputs

  - by BoDiE2003

  I have this code, that checks some ids and enable others, the javascript is pretty clear about what it does, but since it corresponds to some specific id ranges, I cant do just a look until it finishes, but I'm looking a way to do this dynamic and save 40 lines of code (or more), since its not the best way. function loopGroup1() { var a = 0; do { $$('.selectedAuthorities-3_' + a).each(function(chk1) { // watch for clicks chk1.observe('click', function(evt) { dynamicCheckbox1(); }); dynamicCheckbox1(); }); a++; } while (a < 4); } function dynamicCheckbox1() { // count how many of group_first are checked, // doEnable true if any are checked var doEnable = ($$('.selectedAuthorities-3_0:checked').length > 0) ? true : false; var doEnable1 = ($$('.selectedAuthorities-3_1:checked').length > 0) ? true : false; var doEnable2 = ($$('.selectedAuthorities-3_2:checked').length > 0) ? true : false; // for each in group_second, enable the checkbox, and // remove the cssDisabled class from the parent label var i = 0; do { $$('.selectedAuthorities-4_' + i).each(function(item) { if (doEnable || doEnable1 || doEnable2) { item.enable().up('li').removeClassName('cssDisabled'); } else { item.disable().up('li').addClassName('cssDisabled'); } }); i++; } while (i < 4); }; /* * * Loop Group 2 * * */ function loopGroup2() { var a = 0; do { $$('.selectedAuthorities-5_' + a).each(function(chk1) { // watch for clicks chk1.observe('click', function(evt) { dynamicCheckbox2(); }); dynamicCheckbox2(); }); a++; } while (a < 4); } function dynamicCheckbox2() { // count how many of group_first are checked, // doEnable true if any are checked var doEnable3 = ($$('.selectedAuthorities-5_0:checked').length > 0) ? true : false; // for each in group_second, enable the checkbox, and // remove the cssDisabled class from the parent label var i = 0; do { $$('.selectedAuthorities-6_' + i).each(function(item) { if (doEnable3) { item.enable().up('li').removeClassName('cssDisabled'); } else { item.disable().up('li').addClassName('cssDisabled'); } }); i++; } while (i < 4); }; /* * * Loop Group 3 * * */ function loopGroup3() { var a = 0; do { $$('.selectedAuthorities-6_' + a).each(function(chk1) { // watch for clicks chk1.observe('click', function(evt) { dynamicCheckbox3(); }); dynamicCheckbox3(); }); a++; } while (a < 4); } function dynamicCheckbox3() { // count how many of group_first are checked, // doEnable true if any are checked var doEnable4 = ($$('.selectedAuthorities-6_0:checked').length > 0) ? true : false; var doEnable5 = ($$('.selectedAuthorities-6_1:checked').length > 0) ? true : false; // for each in group_second, enable the checkbox, and // remove the cssDisabled class from the parent label var i = 0; do { $$('.selectedAuthorities-7_' + i).each(function(item) { if (doEnable4 || doEnable5) { item.enable().up('li').removeClassName('cssDisabled'); } else { item.disable().up('li').addClassName('cssDisabled'); } }); i++; } while (i < 4); }; /* * * Loop Group 4 * * */ function loopGroup4() { var a = 0; do { $$('.selectedAuthorities-9_' + a).each(function(chk1) { // watch for clicks chk1.observe('click', function(evt) { dynamicCheckbox4(); }); dynamicCheckbox4(); }); a++; } while (a < 4); } function dynamicCheckbox4() { // count how many of group_first are checked, // doEnable true if any are checked var doEnable6 = ($$('.selectedAuthorities-9_0:checked').length > 0) ? true : false; var doEnable7 = ($$('.selectedAuthorities-9_1:checked').length > 0) ? true : false; // for each in group_second, enable the checkbox, and // remove the cssDisabled class from the parent label var i = 0; do { $$('.selectedAuthorities-10_' + i).each(function(item) { if (doEnable6 || doEnable7) { item.enable().up('li').removeClassName('cssDisabled'); } else { item.disable().up('li').addClassName('cssDisabled'); } }); i++; } while (i < 4); };

• extension method phone format with country code as parameter

  - by frenchie

  Hi, I'm writing an extension method called ToPhoneFormat that formats a string of digits to phone numbers. Is it possible to add a parameter to the method that would enable me to call it like this: MyPhoneString.ToPhoneFormat(international code) That way, I could write MyPhoneString.ToPhoneFormat(1); to format a US phone number and MyPhoneString.ToPhoneFormat(33) to format a French phone number. I already wrote the method that does the formatting but I'm wondering how to build the constructor so that it works with a parameter when I'm calling it. Thanks.

• problem with drupal view and php code

  - by czuroski

  Hello, I have a view set up in drupal and I am using some jquery code within the view which hides some data based upon a text box value. Everything is working fine for me when I am logged in. When I log out and access the block anonymously, it doesn't work correctly. I am somewhat new to drupal, and don't know where to begin troubleshooting. I assume it is a permissions issue, but on the view, on the content type, where? If anyone could give me some direction on where to start looking, I would greatly appreciate it. Thanks

• How to get all n sets of three consecutives elements in an array or arraylist with a for statement ?

  - by newba

  Hi, I'm trying to do a convex hull approach and the little problem is that I need to get all sets of three consecutive vertices, like this: private void isConvexHull(Ponto[] points) { Arrays.sort(points); for (int i = 0; i <points.length; i++) { isClockWise(points[i],points[i+1],points[i+2]); } //... } I always do something that I don't consider clean code. Could please help me find one or more ways to this? I want it to be circular, i.e., if my fisrt point of the a set is the last element in the array, the 2nd element will be the 3rd in the list and the 3rd in that set will be the the 2nd element in the list, and so on. They must be consecutive, that's all.

• Training new employees on undocumented code

  - by glowcoder

  Our company has a large codebase (2500+ classes/interfaces in just the core alone, many more in other projects) for our flagship software product. We've never really hired more than one developer at a time, so we don't have a real training process. We're going to be bringing in 2-5 more developers now, and probably more in the near future (to put things into perspective, we have 7 right now.) Obviously, we would like to get these guys up to speed as soon as possible. The catch - almost all of our classes (95%+) are completely undocumented. No javadoc, no design docs, basically completely undocumented. What strategies can we employ to bring the new developers up to speed? I'd like to consider situations that include the existing code getting documented, but it's possible management won't allow for the time to get that done, so I also must consider situations where that won't happen. Has anyone been there before? What worked well for you? Thanks!

• assistance with fxcop

  - by amateur

  I am at present developing a mvc4 project that comunicates to a set of wcf services. I am setting such up in tfs build for a team of developers. I am very much a newbie to fxcop and code analysis in general. I am currently researching it and have some questions following this: Is it recommended to use the rules that come with fxcop? Should it be included as a build task during builds? What is the value from it? Are there guidelines to what rules to abide by or is it best to go with the default? Is it correct to run the analysis as a post build event? I am a newbie to fxcop and would like some feedback. I am as it is integrating stylecop in to my build.

• MVC Html Layout C# code formatting

  - by Andrew Florko

  I insert into asp.net mvc views C# logic that manages layout like the following: <% if (Model.People.Count > 0 ) { %> <% foreach (var person in Model.People) { %> ... <% }} else { %> <span class="error">Sorry, no people</span> <%} %> I try to minimize <% % code placing "{" symbol on the same line as it's condition (java-style). Html layout looks more clear to me after that. Do you apply C# formatting rules to <% % html injections "}" should be on a new line or manage layout in different way? Thank you in advance!

• Controlling symbol generation in Clojure macros

  - by mikera

  I'm trying (as a self-learning exercise) to create a Clojure macro that will generate code to apply a function to a sequence of integers and sum the result, e.g. f(0) + f(1) + f(2) + f(3) This is my attempt: (defmacro testsum [func n] `(fn [x#] (+ ~@( map (fn [i] `(~func x#)) (range n))))) However something seems to go wrong with the x# gensym and I end up with two different versions of x and hence the function doesn't work: (macroexpand '(testsum inc 3)) gives: (fn* ([x__809__auto__] (clojure.core/+ (inc x__808__auto__) (inc x__808__auto__) (inc x__808__auto__)))) This is pretty much exactly what I want apart from the different 809 and 808 versions of x..... What am I doing wrong? I thought that the auto gensym was meant to create a single unique symbol for exactly this kind of purpose? Is there a better way of doing this?

• Why Doesn't This Java Code Skip Lines with #?

  - by Nathan

  I'm trying to allow an external .txt file that is read by a Java script be able to have some comments in the beginning of the file so others can easily edit it and add more to it. But if the file contains # (the sign designated for a line that is a comment) it just returns the error that there is a "Format Error in file" (the IOException - so it is getting past that first "IF"...) Can someone help? Here's the portion of the code that deals with commenting lines out of the .txt file being called earlier in the script: while ((line = br.readLine()) != null) { line = line.trim(); if (line.length() < 1 || line.charAt(0) == '#') { // ignore comments continue; } final String[] parts = line.split("="); if (parts.length != 2) { throw new IOException("Format error in file " + JLanguageTool.getDataBroker().getFromRulesDirAsUrl(getFileName()) + ", line: " + line); }

• Why do Java source files go into a directory structure?

  - by bdhar

  Suppose that I am creating a Java project with the following classes com.bharani.ClassOne com.bharani.ClassTwo com.bharani.helper.HelperOne com.bharani.helper.support.HelperTwo with files put immediately under the folder 'src' src/ClassOne.java src/ClassTwo.java src/HelperOne.java src/HelperTwo.java and compile them using the command $ javac src/*.java -d classes (assuming that classes directory exists) The compiler compiles these files and put the class files in appropriate sub-directories inside the 'classes' directory like this classes/com/bharani/ClassOne.class classes/com/bharani/ClassTwo.class classes/com/bharani/helper/HelperOne.class classes/com/bharani/helper/support/HelperTwo.class Because the spec mandates that the classes should go inside appropriate directory structure. Fine. My question is this: When I use an IDE such as Eclipse or NetBeans, they create the directory structure for the source code directory ('src' directory here) also. Why is that? Is it mandatory? Or, is it just a convention? Thanks.

I have to do this because I store page layouts in the database and each our different for each other, however in some cases I want to use dynamic content for some of the pages. assume $query_from_db is the string returned from the database. php should only eval() the code in between <?php and ?> $query_from_db = '<div> <?php //php to run function dosomething() { //bleh } ?> </div> '; php echo eval($query_from_db);

• 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?

• Add code before initialization of units in Delphi

  - by Alan Clark

  Is there a place where I can add code that will be executed before unit initialization? The reason I want to do this is I need to change the DecimalSeparator, this has to be done before the initialization of some units. I have put it in the project source, before Application.Initialize but it is too late by then. As I see it the only choice I have is to put it in the initialization of the unit that needs the DecimalSeparator to be changed, is this the case? Thanks in advance for any advice.

• code folding in Visual Studio for F#

  - by Yin Zhu

  I find that I tend to write long source files in F#. Some open source projects in F# also have long source files, e.g. FPersec and F# for excel. So it would be very helpful if code folding (even very limited support) is available in VS for F#. E.g. in a module, we can fold out functions that are stable, only leave functions that are subject to change unfold. Is this feature easy to be supported, e.g. by a third party vendor?

• Metric to measure object-orientedness

  - by Jono

  Is there a metric that can assist in determining the object-orientedness of a system or application? I've seen some pretty neat metrics in the .NET Reflector Add-ins codeplex project, but nothing like this yet. If such a metric doesn't exist, would it even be possible or useful? There are the 3 supposed tenets of object-oriented programming: encapsulation, inheritance, and polymorphism; a tool that ranked programs against these might be able to show areas of a C# (or similar) code base where the whole object-oriented ideal was discarded, and perhaps how many bugs are associated with that area versus the rest of the project.
