• Blackberry - How to get Field Labels from PIMItem

  - by Taha

  How can we get Field Labels from PIMItem. The following code is with PIMList String label = pimList.getAttributeLabel( blackBerryContact.getAttributes(Contact.TEL, i)); But i have PIMItem. There is a method PIMItem.getPIMList() which returns null for me in the code below. THE API at http://www.blackberry.com/developers/docs/5.0.0api/index.html says "getPIMList() Gets the PIMList associated with this item." Below is sample code that i am trying to achive - // Load the address Book and allow the user to select a contact BlackBerryContactList contactList = (BlackBerryContactList) PIM.getInstance().openPIMList(PIM.CONTACT_LIST,PIM.READ_ONLY); PIMItem userSelectedContact = contactList.choose(); // Now get the Field labels for contact numbers for userSelectedContact

• In vim is there a way to delete without putting text in the register?

  - by Edward Tanguay

  Using vim I often want to replace a block of code with a block that I just yanked. But when I delete the block of code that is to be replaced, that block itself goes into the register which erases the block I just yanked. So I've got in the habit of yanking, then inserting, then deleting what I didn't want, but with large blocks of code this gets messy trying to keep the inserted block and the block to delete separate. So what is the slickest and quickest way to replace text in vim? is there a way to delete text without putting it into the register? is there a way to say e.g. "replace next word" or "replace up to next paragraph" or is the best way to somehow use the multi-register feature?

• Implicit and Explicit implementation of interface.

  - by Amby

  While working on a upgrade i happened to come across a code like this. interface ICustomization { IMMColumnsDefinition GetColumnsDefinition(); } class Customization : ICustomization { private readonly ColumnDefinition _columnDefinition; //More code here. public ColumnsDefinition GetColumnsDefinition() { return _columnDefinition; } ColumnsDefinition ICustomization.GetColumnsDefinition() //redundant { return GetColumnsDefinition(); } } My question is: Is there any need/use of 'explicit' implementation of interface in this piece of code? Will it create any problem if i remove the method (explicit implementation of interface) that i have marked "redundant" above? PS: I understand that explicit implementation of interface is very important, and it can be used when we need to give access to a method at interface level only, and to use two interface with same signature of method.

• How to use TDD in a not very "Testy" environment

  - by dbemerlin

  I work in a company where OOP is... well, not fobidden, but at least frowned upon as "too complex". My coworkers write lots of 100+ lines functions and they are usually all in a "funcs.inc.php" or "something.inc.php", if they use any functions at all, often they don't since copy-paste is faster. I would love to start using TDD at least for the code i write but as i have to interface with their code i can't see how to begin. It's not legacy code as they are actively developing it and i don't want to modify their code as i don't want to provoke conflicts. Which approach would you suggest, except for changing the company?

• Tracking a Flash banner advert using clickTag and Google Analytics

  - by alistair.mp

  Hello. I'm trying to find out if there is a way of using clickTag and Google Analytics to track outgoing banner clicks. clickTag code: on (release) { if (clickTAG.substr(0,5) == "http:") { getURL(clickTAG); } } Maybe someone can tell me whether the following would work: on (release) { if (clickTAG.substr(0,5) == "http:") { getURL("javascript:pageTracker._trackPageview('/somebannerad');"); getURL(clickTAG); } } but I would ideally like a solution that worked with the standard clickTag code and didn't involve changing any code in the flash file. Anyone have any ideas? Thanks

• How do I edit an interface builder object programmatically?

  - by Evelyn

  I created a label using Interface Builder, and now I want to set the background color of the label using code instead of IB's color picker. (I want to do this so that I can define the color using RGB and eventually change the colorspace for the label.) I'm in cocoa. How do I edit the attributes of an IB object using code? My code looks like this: //.h file #import <UIKit/UIKit.h> @interface IBAppDelegate : NSObject { UILabel *label; } @property (nonatomic, retain) IBOutlet UILabel *label; @end //.m file #import "IBAppDelegate.h" @implementation IBAppDelegate @synthesize label; (memory stuff...) @end

• pyopengl: Could it replace c++ ?

  - by Tom

  Hi everyone. I'm starting a computer graphics course, and I have to choose a language. Choices are between C++ and Python. I have no problem with C++, python is a work in progress. So i was thinking to go down the python road, using pyopengl for graphics part. I have heard though, that performance is an issue. Is python / pyopengl mature enough to challenge C++ on performance? I realize its a long shot, but I'd like to hear your thoughts, experiences on uses of pyopengl. Thanks in advance.

• Selecting a UserControl from XAML

  - by kmontgom

  I'm working on a problem right now where I need to embed a UserControl inside another UserControl. But, I need to determine at runtime which embedded UserControl to instantiate. This implies to me that some form of data binding and/or template selection mechanism has to be invoked, but I'm not sure how to proceed with the pure XAML approach. If I was to do this with code, I would define some sort of container control in the parent UserControl, and then in the code-behind, implement some logic which would instantiate the appropriate child UserControl and then insert it as Content into the specified container in the parent UserControl. Can this be done using only XAML, or is some sort of code-behind required?

• setting UAC settings of a file in C#

  - by Inam Jameel

  Hi guys. i want to give a file(already present on the client computer .exe) permissions to always execute with administrative permissions. please note that the file i wants to give permissions is already on target machine. and i want to change permissions of that file through another program written in c# and it has administrative permissions to do everything. kindly let me know how to do it i am using this code System.Security.AccessControl.FileSecurity fs = File.GetAccessControl(@"c:\inam.exe"); FileSystemAccessRule fsar = new FileSystemAccessRule("Everyone", FileSystemRights.FullControl, AccessControlType.Allow); fs.AddAccessRule(fsar); File.SetAccessControl(@"c:\inam.exe", fs); this code will change the permissions correctly but still when i execute inam.exe after executing this code the UAC not appeared and also the inam.exe cant perform administrative operations. actually i have already deployed an application on more than 10,000 clients so wants to release a patch to resolve the administrative rights issue.

• Trouble Emitting Object Array using Reflection.Emit

  - by JoeGeeky

  I am trying to Emit what I thought would be a simple object array that would result in code similar to the below example object[] parameters = new object[] { a, b, }; When I write the above code in C# using VS, I get the following IL. As expected this works. .locals init ( [0] object[] parameters, [1] object[] CS$0$0000) However, when I try and Emit IL directly, I only ever get a one index init array. Can someone help tell me where I've gone wrong here? Here is the Emit code I'm using: int arraySize = 2; LocalBuilder paramValues = ilGenerator.DeclareLocal(typeof(object[])); paramValues.SetLocalSymInfo("parameters"); ilGenerator.Emit(OpCodes.Ldc_I4_S, arraySize); ilGenerator.Emit(OpCodes.Newarr, typeof(object)); ilGenerator.Emit(OpCodes.Stloc, paramValues); Here is the resulting IL: .locals init ( [0] object[] objArray) The rest of the resulting IL is identical between the two solutions, but for some reason the .locals init is different.

• importing same module more than once

  - by wallacoloo

  So after a few hours, I discovered the cause of a bug in my application. My app's source is structure like: main/ __init__.py folderA/ __init__.py fileA.py fileB.py Really, there are about 50 more files. But that's not the point. In main/__init__.py, I have this code: from folderA.fileA import * in folderA/__init__.py I have this code: sys.path.append(pathToFolderA) in folderA/fileB.py I have this code: from fileA import * The problem is that fileA gets imported twice. However, I only want to import it once. The obvious way to fix this (to me atleast) is to change certain paths from path to folderA.path But I feel like Python should not even have this error in the first place. What other workarounds are there that don't require each file to know it's absolute location?

• Cannot hide a UIButton

  - by Neurofluxation

  Hey again, I have the following code: visitSite.hidden = YES; For some reason, when I click a UIButton and call this piece of code, the visitSite button does not hide.

• SICP making change

  - by RyanD

  So; I'm a hobbiest who's trying to work through SICP (it's free!) and there is an example procedure in the first chapter that is meant to count the possible ways to make change with american coins; (change-maker 100) = 292. It's implemented something like: (define (change-maker amount) (define (coin-value n) (cond ((= n 1) 1) ((= n 2) 5) ((= n 3) 10) ((= n 4) 25) ((= n 5) 50))) (define (iter amount coin-type) (cond ((= amount 0) 1) ((or (= coin-type 0) (< amount 0)) 0) (else (+ (iter amount (- coin-type 1)) (iter (- amount (coin-value coin-type)) coin-type))))) (iter amount 5)) Anyway; this is a tree-recursive procedure, and the author "leaves as a challenge" finding an iterative procedure to solve the same problem (ie fixed space). I have not had luck figuring this out or finding an answer after getting frustrated. I'm wondering if it's a brain fart on my part, or if the author's screwing with me.

• How can I pass data from an aspx page to an ascx modal popup?

  - by Erick B

  I'm fairly new to ASP.NET and trying to learn how things are done. I come from a C# background so the code-behind portion is easy, but thinking like a web developer is unfamiliar. I have an aspx page that contains a grid of checkboxes. I have a button that is coded via a Button_Click event to collect a list of which rows are checked and create a session variable out of that list. The same button is referenced (via TargetControlID) by my ascx page's ModalPopupExtender which controls the panel on the ascx page. When the button is clicked, the modal popup opens but the Button_Click event is never fired, so the modal doesn't get its session data. Since the two pages are separate, I can't call the ModalPopupExtender from the aspx.cs code, I can't reach the list of checkboxes from the ascx.cs code, and I don't see a way to populate my session variable and then programmatically activate some other hidden button or control which will then open my modal popup. Any thoughts?

• How to create custom get and set methods for Linq2SQL object

  - by optician

  I have some objects which have been created automatically by linq2SQL. I would like to write some code which should be run whenever the properties on these objects are read or changed. Can I use typical get { //code } and set {//code } in my partial class file to add this functionality? Currently I get an error about this member already being defined. This all makes sense. Is it correct that I will have to create a method to function as the entry point for this functionality, as I cannot redefine the get and set methods for this property. I was hoping to just update the get and set, as this would mean I wouldn't have to change all the reference points in my app. But I think I may just have to update it everywhere.

• Java for each vs regular for -- are they equivalent?

  - by polygenelubricants

  Are these two constructs equivalent? char[] arr = new char[5]; for (char x : arr) { // code goes here } Compared to: char[] arr = new char[5]; for (int i = 0; i < arr.length; i++) { char x = arr[i]; // code goes here } That is, if I put exactly the same code in the body of both loops (and they compile), will they behave exactly the same??? Full disclaimer: this was inspired by another question (Java: are these 2 codes the same). My answer there turned out not to be the answer, but I feel that the exact semantics of Java for-each has some nuances that needs pointing out.

• Consuming RSS Feed In PHP

  - by mrduclaw

  I'm trying to use an RSS feed from my blog on the news section on another site. Everything seems to be working fine until I use something like an ellipsis on my blog. The expected output is: One more time…less fail Although this is no joking matter… The actual output is: One more time?less fail Although this is no joking matter… The problem is that ? should be a .... The code I'm using is the same for the first line (the blog title) and the second line (the blog contents) and that code is: $a = utf8_decode($a); print("$a"); Where $a is the string from the RSS feed. Can anyone point in the right direction why that code would work correctly for the body (second line) and not for the title (first line)? Or suggest a better way to do this? Thanks!

• Why Read In UTF-16LE File Won't Convert "\r\n" Into "\n" In Windows

  - by Dbger

  I am using Perl to read UTF-16LE files in Windows 7. If I read in an ascii file with following code: open CUR_FILE, "<", $asciiFile; Then each "\r\n" in file will be converted into a "\n" in memory; if I read in an UTF-16LE(windows 1200) file with following code: open CUR_FILE, "<:encoding(UTF-16LE)", $utf16leFile; Then "\r\n" will keep unchanged. This inconsistency cause problems when I trying to regexp lines with line breaks. My questions is: Is this how unicode works in Perl & Windows? Or Am I using the wrong code? Thanks so much!

• How to prevent Closure Compiler from renaming "true", "false" and "null"

  - by Armagan Amcalar

  Google Closure Compiler renames all "true", "false" and "null" occurences in code like; var s = true, x = null, V = false; and uses these shorthands instead; in conditions such as; if (someVariable == s) now; Google Analytics code defines it's own "s" variable; overriding the value "true"; and as you can see this causes a lot of problems. I don't want to change GA code; I just want Closure Compiler to quit renaming true etc. Externs do not work. Do you know any way to accomplish this?

• [PHP] DOMDocument load on a page returning 400 Bad Request status

  - by PeteWilliams

  Hiya, I'm trying to use the Last.fm API for an application I'm creating, but am having some problems with validation. If an API request gives an error it returns a code and message in the response XML like this: <lfm status="failed"> <error code="6">No user with that name</error> </lfm> However, the request also returns an HTTP status of 400 (or in some cases 403) which DOMDocument considers an error and so then refuses to parse the XML. Is there any way round this, so that I can retrieve the error code and message? Thanks Pete

  Can't seem to find a fix for this issue I have the following code on the onclick event of an a html tag: AddVacationToCart( { ServiceSupplier:'Kiki', ProductId:'0;11968;0;0;187;1', Name:'Excelsior', NumberOfStars:'*****', TotalPrice:'1620.00', PriceLevelName:'Standard', Currency:'EUR', Status:'', StartDate:'2010-06-17', EndDate:'2010-06-24', NumberOfNights:'7', Rooms:[ { NumberOfAdults:'2', NumberOfChildren:'0', ChildrenAges:[] } ] },'0;11968;0;0;187;1');return false; I also have this code: function AddVacationToCart(vacation, id) { $.post("/ShoppingCart.mvc/AddVacation", vacation, function(data) { var div = $("div[id*=cartv" + id + "]"); var removeFromCartHtml = "Adaugat"; $(div).html(removeFromCartHtml); }, "json"); } This is the code in my ShoppingCartController AddVacation Action: [AcceptVerbs(HttpVerbs.Post)] public ActionResult AddVacation(Vacation test) { ... } The post works as in the (Vacation) test object gets filled with the corresponding properties like ServiceSupplier, ProductId, Name etc. Except the properties of my Rooms field do not get their corresponding values. Any ideeas?

• int vs size_t on 64bit

  - by MK

  Porting code from 32bit to 64bit. Lots of places with int len = strlen(pstr); These all generate warnings now because strlen() returns size_t which is 64bit and int is still 32bit. So I've been replacing them with size_t len = strlen(pstr); But I just realized that this is not safe, as size_t is unsigned and it can be treated as signed by the code (I actually ran into one case where it caused a problem, thank you, unit tests!). Blindly casting strlen return to (int) feels dirty. Or maybe it shouldn't? So the question is: is there an elegant solution for this? I probably have a thousand lines of code like that in the codebase; I can't manually check each one of them and the test coverage is currently somewhere between 0.01 and 0.001%.

• Using the Antenna and J2ME Polish preprocessors interchangeably and setting a variable value

  - by walter

  I have J2ME code, which I want to be able to compile using the J2ME Polish preprocessor or the wtkpreprocessor (antenna). They mostly use the same directives so it usually works, but ... When I want to insert an URL value in the Java code this gives a problem. In Antenna the code would look like this: //#ifdef my.url //# System.out.println("My Url"); //#expand String location = "%my.url%"; //#else System.out.println("Default"); String location = "http://www.some.default.url.com"; //#endif and in J2ME Polish it would look like this: //#ifdef my.url:defined //# System.out.println("My Url"); //#= String location = "${my.url}"; //#else System.out.println("Default"); String location = "http://www.some.default.url.com"; //#endif I want some way in which I can use the preprocessors interchangeably and still be able to set the url in the build.xml, any ideas?

• Am I immoral for using a variable name that differs from its type only by case?

  - by Jason Baker

  For instance, take this piece of code: var person = new Person(); or for you Pythonistas: person = Person() I'm told constantly how bad this is, but have yet to see an example of the immorality of these two lines of code. To me, person is a Person and trying to give it another name is a waste of time. I suppose in the days before syntax highlighting, this would have been a big deal. But these days, it's pretty easy to tell a type name apart from a variable name. Heck, it's even easy to see the difference here on SO. Or is there something I'm missing? If so, it would be helpful if you could provide an example of code that causes problems.

• Exception while opening file

  - by viswanathan

  Hi I have a VC++ application and in my application i have some basic file operations. Below is the defaulting code CStdioFile cFile; CFileException e; CString sReport; CString sHtmlfile = "testreport.html" OutputDebugString((sHtmlfile)); if (!cFile.Open(sHtmlfile,CFile::modeCreate | CFile::modeWrite, &e )) { } The problem is my application executes this piece of code every few minutes. and it works fine. After several runs of the code the cFile.Open() function fails. I tried to get the error message TCHAR szError[1024]; e.GetErrorMessage(szError,1024); OutputDebugString((szError)); The irony is the szError error message is "No error occured". This again works once i restart my application. Any idea why this occurs. Thanks in advance.
