  • Tab versus space indentation in C#

    - by Lars Fastrup
    I sometimes find myself discussing this issue with other C# developers and especially if we use different styles. I can see the advantage of tab indentation allowing different developers to browse the code with their favorite indent size. Nonetheless, I long ago went for two space indentation in my C# code and have stuck with it ever since. Mainly because I often disliked the way statements spanning multiple lines are sometimes messed up when viewing code from other developers using another tab size. Recently a developer at one of my clients approached me and asked why I did not use tabs because he preferred to view code with an indentation size of 4. So my question is: Which style do you prefer and why?

  • Keyboard event issue

    - by Petar Minchev
    Hello guys! I have to capture the following keyboard event in a TextBox - SHIFT + 8(on the numpad). This also means the NumLock will be on. When I try the following, nothing is printed: private void textBox1_KeyDown(object sender, KeyEventArgs e) { if (e.Shift && e.KeyCode == Keys.NumPad8) Console.WriteLine("SHIFT + UP"); } But CTRL + 8(on the numpad) is working. private void textBox1_KeyDown(object sender, KeyEventArgs e) { if (e.Control && e.KeyCode == Keys.NumPad8) Console.WriteLine("CTRL + UP"); } Could someone explain me, why SHIFT + 8 isn't fired, but CTRL + 8 is working? P.S. I wrote + UP, because the user wants to navigate with the numpad arrows and the SHIFT key, but his NumLock will also be on. That's why I catch Keys.NumPad8. All the best, Petar

  • Error "E_UNEXPECTED(0x8000FFFF)" when using CDec/CInt/IsNumeric

    - by Marc vB
    I have encountered a strange problem, which I could solve but don't understand why it did occur. I have build a DLL with COM enabled. In this DLL I have classes that did use the functions CInt, CDec and IsNumeric. If I test these classes from a .NET application then it works ok. But when I called/run these classes from a Win32 application (with COM) then I did get an "E_UNEXPECTED(0x8000FFFF)" error. After some debugging I found out that the problem would go away if I: - replaced IsNumeric with Integer.TryParse or Decimal.TryParse - replaced CInt with Integer.Parse - replaced CDec with Decimal.Parse Can anyone explain this? Again, I could solve it by doing this but I would like to know why.

  • ActiveX communication

    - by Mario Marinato -br-
    I'm developing an ActiveX EXE that exposes an specific class to a third-party software. This third-party software instanciates an object of this class and uses its methods. Strangely, this third-party software destroys its object of my exposed class as soon as it calls an specific method, but I have no idea why this happens. The only clue I have is that this method is the only one that returns a value. All the other ones are simple 'subs' that do not return any value, and when they are called nothing wrong happens. I'm using VB6. Do you guys have any idea of why it's happening?

  • EXC_BAD_ACCESS when not using self.

    - by chris
    I got nabbed by the following bug again and would like some clarification to exactly why it is a bug. I have a simple UITableView that loads some data: // myclass.h @property (nonatomic, retain) NSArray *myData // myclass.m @synthesize myData; - (void) viewDidLoad { ... myData = someDataSource // note the lack of self } - (UITableViewCell *) cellForRowAtIndexPath ... { ... cell.textLabel.text = [self.myData objectAtIndex:indexPath.row]; // EXC_BAD_ACCESS } The table first loads fine, but when scrolling up enough that one of the cells is totally out of the view I then get the EXC_BAD_ACCESS error. Am I missing something in regards to @property retain. My understanding is that it releases anything that the pointer was previously pointing to before the reassignment. If I am correct then why would not using self. cause any problems? Thanks for the help.

  • What is the advantage of using static methods in Python?

    - by Curious2learn
    I ran into unbound method error in python with the code class Sample(object): '''This class defines various methods related to the sample''' def drawSample(samplesize,List): sample=random.sample(List,samplesize) return sample Choices=range(100) print Sample.drawSample(5,Choices) After reading many helpful posts here, I figured how I could add @staticmethod above to get the code working. I am python newbie. Can someone please explain why one would want to define static methods? Or, why are not all methods defined as static methods. Thanks in advance.

  • Objective c key path operators @avg,@max .....

    - by davide
    arr = [[NSMutableArray alloc]init]; [arr addObject:[NSNumber numberWithInt:4]]; [arr addObject:[NSNumber numberWithInt:45]]; [arr addObject:[NSNumber numberWithInt:23]]; [arr addObject:[NSNumber numberWithInt:12]]; NSLog(@"The avg = %@", [arr valueForKeyPath:@"@avg.intValue"]); This code works fine, but why? valueForKeyPath:@"@avg.intValue" is requesting (int) from each NSNumber, but we are outputting a %@ string in the log. If i try to output a decimal %d i get a number that possibly is a pointer to something. Can somebody explain why the integers become NSNumbers when i call the @avg operator?

  • Redirect print in Python: val = print(arg) to output mixed iterable to file

    - by emcee
    So lets say I have an incredibly nested iterable of lists/dictionaries. I would like to print them to a file as easily as possible. Why can't I just redirect print to a file? val = print(arg) gets a SyntaxError. Is there a way to access stdinput? And why does print take forever with massive strings? Bad programming on my side for outputting massive strings, but quick debugging--and isn't that leveraging the strength of an interactive prompt? There's probably also an easier way than my gripe. Has the hive-mind an answer?

  • How to connect 2 mysql tables with 2 connection string

    - by denonth
    Hi all I need to connect 2 tables from 2 mysql databases that have 2 different connection strings and each is on the different server. I have this query: cmd = new MySqlCommand(String.Format("INSERT INTO {0} (a,b,c,d) SELECT (a,b,c,d) FROM {1}", ConfigSettings.ReadSetting("main_table"), ConfigSettings.ReadSetting("main_table")), con); So both table have the same columns. Thats why I have only one ConfigSettings.ReadSetting("main_table") for both of them as they are same. I have 2 connection strings and each is pointing to their server: con.ConnectionString = ConfigurationManager.ConnectionStrings["con1"].ConnectionString; con2.ConnectionString = ConfigurationManager.ConnectionStrings["con2"].ConnectionString; How to make this cmd to be workking with 2 different connection strings and with the same name for the table. Table name will change that's why it is saved in config.

  • Win32: BitTest, BitTestAndComplement, ... <- How to disable this junk?

    - by Mordachai
    WinNT.h has the following lines in it, in the VS2008 SP1 install: #define BitTest _bittest #define BitTestAndComplement _bittestandcomplement #define BitTestAndSet _bittestandset #define BitTestAndReset _bittestandreset #define InterlockedBitTestAndSet _interlockedbittestandset #define InterlockedBitTestAndReset _interlockedbittestandreset I have a number of templates that are based on BitTest<() Does anyone know of a simple way to disable these #defines? Oftentimes MS does provide a #define XXX symbol which, if defined, will disable some offending portion of their header - e.g. NOMINMAX. I have been unable to find such a solution to the above problem. If you share frustration with Microsoft's many dubious choices, the read on. If not, stop here. ;) Editorializing: Why couldn't Microsoft just use the _bittest itself??? Or why couldn't they use BITTEST like every knows you should - always use all-caps for macros! Microsoft is still #defining things in 2010?! WTF?

  • Requesting a website by client side script = Cross Side Scripting Hack. But requesting a website by

    - by 1s2a3n4j5e6e7v
    Generally, when we want to show the contents of some web page in the same page, we go for ajax requests. If say, I request to a web page in different domain with AJAX, it is not allowed because of the Cross side scripting error. But why is it allowed to access via a server side page. For e.g. we can use CURL in php to access any site.? Why is this feature OK for server side scripting and NOT OK for Client Side Scripting?

  • How should I use color in my application? Single, Theme, or Chaos?

    - by CodeSlave
    How should I be using color in my application? I have over a 100 different forms (windows) in my application, and the default windows grey seems like a bad choice to me. One school of thought says pick one neutral color, and use the same one everywhere. Another school of thought says pick a set of neutral colors, and use them same ones within a group of form (e.g., shipping screens might be light green, receiving screens light orange, user administration screens light blue, etc.). The final school of thought says make every form different. We've got millions of colors, why not use them? What should I do and why?

  • php shuffle() returns one item

    - by mike
    Anyone have any idea why shuffle() would only return 1 item? when using: $array2 = shuffle($array1); with the following array($array1): Array ( [0] => 1 [1] => 5 [2] => 6 [3] => 7 [4] => 8 [5] => 10 [6] => 11 [7] => 12 [8] => 13 [9] => 14 ) The output of: print_r($array2); is simply: 1 Any idea as to why it would not only not shuffle the array, but knock off the remaining 9 items in the array? thanks!

  • Myself throwing NullReferenceException... needs help

    - by Amit Ranjan
    I know it might be a weird question and its Title too, but i need your help. I am a .net dev , working on platform for the last 1.5 years. I am bit confused on the term usually we say " A Good Programmer ". I dont know ,what are the qualities of a good programmer ? Is the guy who writes a bug free code? or Can develop applications solely? or blah blah blah...lots of points. I dont know... But as far i am concerned , I know I am not a good programmer, still in learning phase an needs a lot to learn in coming days. So you guys are requested to please help me with this two problems of mine My first problem is regarding the proper Error Handling, which is a most debatable aspect of programming. We all know we use ` try { } catch { } finally { } ` in our code to manage exception. But even if I use try { } catch(exception ex) { throw ex } finally { } , different guys have different views. I still dont know the good way to handle errors. I can write code, use try-catch but still i feel I lacks something. When I saw the codes generated by .net fx tools even they uses throw ex or `throw new Exception("this is my exception")`.. I am just wondering what will be the best way to achieve the above. All means the same thing but why we avoid something. If it has some demerits then it must be made obselete.Anyways I still dont have one [how to handle errors efficiently?]. I generally follow the try-catch(execoption ex){throw ex}, and usually got stucked in debates with leads why you follow this why not that... 2.Converting your entire code blocks in modules using Design patterns of some OOPs concepts. How do you guys decide what architeture or pattern will be the best for my upcoming application based on its working, flow etc. I need to know what you guys can see that I can't. Since I know , I dont have that much experience but I can say, with my experience that experience doesnot comes either from degree/certificates or success you made instead it cames from failures you faced or got stucking situations. Pleas help me out.

  • Rank Source Control Options-VSS vs CVS vs none vs your own hell

    - by Roman A. Taycher
    It seems like a lot of people here and on many programmer wikis/blogs/ect. elsewhere really dislike VSS. A lot of people also have a serious dislike for cvs. In many places I have heard a lot of differing opinions on whether or not using VSS or cvs is better or worse then using no source control, please rate the worst and explain why!!!!! you rated them this way. Feel free to throw in your own horrible system in the rankings. If you feel it depends on the circumstances try to explain the some of the different scenarios which lead to different rankings. (note:I see a lot of discussion of what is better but little of what is worse.) second note: while both answers are nice I'm looking less for good replacements and more for a comparison of which is worse and more importantly why!
