• Why self.view is not available

  - by amok

  I have this code in the main view controller and it is working just fine and as I wanted. loadingActionSheet = [[UIActionSheet alloc] initWithTitle:@"Posting To Twitter..." delegate:nil cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:nil]; [loadingActionSheet showInView:self.view]; I wanted that code to be reusable from different part of the project so I moved it in a separate file (UIView based). The poblem that I am facing is that self.view is not available there and I don't know why because I am learning and I don't know enough to understand what I am missing. What do I have to do/add/change to have the actionsheet shown in my current view even if that code lives somewhere else?

• Preprocessor directive to test if this is C or C++

  - by Collin

  I'm trying to find a standard macro which will test whether a header file is being compiled as C or as C++. The purpose of this is that the header may be included by either C or C++ code, and must behave slightly differently depending on which. Specifically: In C, I need this to be the code: extern size_t insert (const char*); In C++, I need this to be the code: extern "C" size_t insert (const char*); Additionally, is there a way to avoid putting #ifdef's around every declaration in the header?

• Combining several static archives into a new one

  - by knight666

  I'm making a game engine for mobile devices. I want to compile my code, link it against a few static libraries and then combine my compiled code with those static libraries to form a new static library. However, my Google Fu is abandoning me. Suppose I have static libraries a.a, b.a and c.a and my code. I want to compile all that into awesome.a. How can I do that? I'm using CodeSourcery's arm-none-linux-gnueabi-ar by the way. Thanks in advance.

• BASH Script to cd to directory with spaces in pathname

  - by Rails Newbie

  Argggg. I've been struggling with this stupid problem for days and I can't find an answer. I'm using BASH on Mac OS X and I'd like to create a simple executable script file that would change to another directory when it's run. However, the path to that directory has spaces in it. How the heck do you do this? This is what I have... Name of file: cdcode File contents: cd ~/My Code Now granted, this isn't a long pathname, but my actual pathname is five directories deep and four of those directories have spaces in the path. BTW, I've tried cd "~/My Code" and cd "~/My\ Code" and neither of these worked. If you can help, THANKS! This is driving me crazy!!

• Unable to link to opengl libraries? DOS / MSVC

  - by Mark

  Is there something wrong with this link.exe command line? OpenGL32.lib and Glu32.lib are found at both of the LIBPATH directories. Is it possible the libraries are somehow incompatible? Is there a way to have the link.exe say that instead of unresolved external symbol? Googling shows that this error usually means the libraries are not found, but they are there.

• Xcode 3.2 not recompiling changed files

  - by Jason

  I've been programming a new iPhone application and everything has been chugging along fine, until this afternoon when I noticed that any changes I was making were not being reflected in the actual app! Even code that throws errors isn't getting picked up by the compiler. To get around this, I have taken to the following procedure: Finish making my edits, and add code to the file which will always throw a compiler error. Right-click the file I have just edited, and hit "Compile" to just compile that one file; it will throw the error. Remove the error-producing code, and again right-click and "Compile" the one file. Build the whole project This is quite annoying, and I can't figure out why this would suddenly happen to my Xcode project. Any thoughts on what could be causing this, and how to fix it?

• Strange exception phenomenon in Windows 7

  - by Level 2

  I spot some interesting articles about exception handle in CodeProject http://www.codeproject.com/KB/cpp/seexception.aspx After reading, I decided to do some experiment. The first time I try to execute the following code char *p; p[0] = 0; The program died without question. But After several times when I executed the same problem binary code, it magically did fine. Even the following code is doing well. Any clue or explanation? char *p p[1000] = 'd'; cout<<p[1000]<<endl; My O/S is Windows 7 64bit and compiler is VS2008 rc1.

• jQuery: inherit functions to several objects

  - by Fuxi

  hi, i made several table-based-widgets (listview-kind-of) which all have the same characteristics: styling odd/even rows, hover on/off, set color onClick, deleting a row when clicking on trash-icon. so it's always the same (prototype-)code for each widget. is there a way to have the code only once then simply apply/inherit it to all widgets? 2nd, here's some of the code - could this be optimized? var me = this; $("tr",this.table).each(function(i) { var tr = $(this); tr.bind("mouseover",function(){me.hover(tr,true)}); tr.bind("mouseout",function(){me.hover(tr,false)}); tr.bind("click",function(){me.Click(tr)}); }); $("tr").filter(":odd").addClass("odd");

• Is there a file diff tool that allows for exceptions?

  - by Kevin

  We currently use Beyond Compare 3.0 and I am quite pleased with it. However, it would be great if I could easily specify an exclusion for a specific one-time case. This is needed when I am doing a code review of some refactoring. For instance: Old code doSomething(ConstantsInterface.FOOBAR); New code: doSomething(BetterEnumeration.FOOBAR); In this case, I have hundreds of changes that I am reviewing that are essentially all the same exact change and I just want to see the exceptions. It would be great if I could easily specify an exception that indicates these two cases are equal. I know of a way to do it in the grammar, but it is tedious and cumbersome in the case where there are ten or so exceptions. Any other tips?

• How to replace a codebehind method with an aspx method using ternary operator

  - by user466663

  I have an asp:hyperlink control as part of a gridview template. The code in the aspx page is given below: asp:HyperLink runat="server" ID="lnkEdit" ToolTip="Edit article" NavigateUrl='<%# GetUrl(Eval("ID").ToString(), Eval("CategoryID").ToString()) %' ImageUrl="~/Images/Edit.gif" The NavigateUrl value is obtained from the codebehind method GetUrl(string, string). The code works fine and is as follows: protected string GetUrl(string id, string categoryID) { var CategoryID = string.Empty; if (!String.IsNullOrEmpty(Request.QueryString["CatID"])) { CategoryID = Request.QueryString["CatID"].ToString(); } else if (!String.IsNullOrEmpty(categoryID)) { CategoryID = categoryID; } return "~/TBSArticles/WriteOrEditArticle.aspx?ID=" + id + "&CatID=" + CategoryID; } I want to replace the code behind method by using a ternary operator within the aspx page. I tried something like below, but didn't work: asp:HyperLink runat="server" ID="lnkEdit" ToolTip="Edit article" NavigateUrl='<%# "~/TBSArticles/WriteOrEditArticle.aspx?ID=" + Eval("ID") + "&CatID=" + Eval(this.Request.QueryString["CatID"].ToString()) != ""? this.Request.QueryString["CatID"] : Eval("CategoryID")) %' ImageUrl="~/Images/Edit.gif" Any help will be greatly appreciated.

• Backbone.js "model" query

  - by Novice coder

  I'm a learning coder trying to understand this code from a sample MVC framework. The below code is from a "model" file. I've done research on Backbone.js, but I'm still confused as to exactly how this code pull information from the app's database. For example, how are base_url, Model.prototype, and Collection.prototype being used to retrieve information from the backend? Any help would be greatly appreciated. exports.definition = { config : { "defaults": { "title": "-", "description": "-" }, "adapter": { "type": "rest", "collection_name": "schools", "base_url" : "/schools/", } }, extendModel: function(Model) { _.extend(Model.prototype, { // Extend, override or implement Backbone.Model urlRoot: '/school/', name:'school', parse: function(response, options) { response.id = response._id; return response; }, }); return Model; }, extendCollection: function(Collection) { _.extend(Collection.prototype, { // Extend, override or implement Backbone.Collection urlRoot: '/schools/', name: 'schools', }); return Collection; } }

• How to run a widget inside of an activity in Android?

  - by user220755

  I have a widget built to give the user the chance to choose the date (I did not build it, I am building on top of an open source software). Now, I need to display this widget inside of a class that extends the activity class in Android. Let me show some code. Let us say this is the activity class: public class RandomClass extends Activity { public void onCreate(Bundle savedInstanceState) { // I want to run the widget here when the class is created // (the activity is created) } } The widget i want to run is a widget that lets the user choose the date. I know I code use one of Android's activities but I need to build on top of the code so I have to run it inside of the activity class I created. Sorry if this is not clear, ask any questions and i will be more than glad to answer them and clarify.

• How to use TestAndSet() for solving the critical section problem?

  - by Dan Mantyla

  I'm studying for an exam and I'm having difficulty with a concept. This is the pseudo code I am given: int mutex = 0; do { while (TestAndSet(&mutex)); // critical section mutiex = 0; // remainder section } while (TRUE); My instructor says that only two of the three necessary conditions (mutual exclusion, progress, and bounded waiting) are met with this code, but I don't understand which one isn't being met...?? How should the code be modified to support the missing condition to solve the critical region problem? Thanks in advance for any insight!

• RSpec: in-depth differences between before(:all) and before(:each)

  - by gmile

  Ok, so I've ran into a very strange issue, directly connected with before blocks. I'm doing a integration testing via Watir and RSpec. For a simple test to check if user can perform a login I'm creating a 'user' record in the db by means of factory_girl. So I put the following code: before(:each) do @user = Factory(:user) end if "should perform a login" do # do stuff end In do stuff I call a browser and see how the user tries to login. Unfortunately, somehow he cannot do that — "Username isn't valid". After some investigation I discovered that if I put the code for creating user in before(:all) block, everything magically works. How's that? What's the difference between :all and :each in this context? Also, If I put the code for creating user actually in the test body, it still doesn't work (i.e. user somehow isn't added to the DB or something).

• Inability to detect the Output from inside a SSIS script component

  In the script of the script components the Output buffer is not being detected as an existing component. I am trying to use the following piece of code Output0Buffer.AddRow(); within the public override void Input0_ProcessInputRow(Input0Buffer Row) method. I know it should be available within this method because at the moment I am copying and using a component from a previous project that has this code and it works. but when I create a new component and put the same code in it doesn't Can any one explain why this is happening?

• Sum up values in SQL once all values are available

  - by James Brown

  I have events flowing into a MySQL database and I need to group and sum the events to transactions and store away into another table. The data looks like: +----+---------+------+-------+ | id | transid | code | value | +----+---------+------+-------+ | 1 | 1 | b | 12 | | 2 | 1 | i | 23 | | 3 | 2 | b | 34 | | 4 | 1 | e | 45 | | 5 | 3 | b | 56 | | 6 | 2 | i | 67 | | 7 | 2 | e | 78 | | 8 | 3 | i | 89 | | 9 | 3 | i | 90 | +----+---------+------+-------+ The events arrive in batches and I would like to create the transaction by summing up the values for each transid, like: select transid, sum(value) from eventtable group by transid; but only after all the events for that transid have arrived. That is determined by the event with the code e (b for the beginning, e for the end and i for varying amount of intermediates). Being a novice in SQL, how could I implement the requirement for the existance of the end code before the summing?

  So I managed to setup pods and create my custom tables. Now I want to revamp my theme so that it pulls data from the POD table. Doesn't seem to be working... This is what I did.. I have a Pod called 'project_type' with a name (string) and a code (string) field. Have also added 3 entries via the admin system. I made a copy of the default wordpress plugin and renamed it to myTheme and activated it. Inside index.php of myTheme, I removed all the default code.. and have just the POD specific code as shown below. <?php echo "Hello World"; $p = new Pod('project_type'); echo $p->getTotalRows(); ?> However, when I reload my page, only Hello World shows up? A bit new to Wordpress so kindly advice.
