  • Is there an easy way to convert C# classes to PHP?

    - by John
    I am used to writing C# Windows application. However I have some free hosted PHP web space that I would like to make use of. I have a basic understanding of PHP but have never used it's object oriented capabilities. Is there an easy way to convert C# classes to PHP classes or is it just not possible to write a fully object oriented application in PHP? Update: There are no reliance on the .NET framework beyond the basics. The main aim would be to restructure the class properties, variable enums, etc. The PHP will be hosted on a Linux server.

  • Future proof Primary Key design in postgresql

    - by John P
    I've always used either auto_generated or Sequences in the past for my primary keys. With the current system I'm working on there is the possibility of having to eventually partition the data which has never been a requirement in the past. Knowing that I may need to partition the data in the future, is there any advantage of using UUIDs for PKs instead of the database's built-in sequences? If so, is there a design pattern that can safely generate relatively short keys (say 6 characters instead of the usual long one e6709870-5cbc-11df-a08a-0800200c9a66)? 36^6 keys per-table is more than sufficient for any table I could imagine. I will be using the keys in URLs so conciseness is important.

  • Renaming ICSharpCode.SharpZipLib.dll

    - by John B.
    Hi, well I am having a problem renaming the ICSharpCode.SharpZipLib.dll file to anythig else. I am trying to shorten the file name. I reference the assembly in the project, but when the program reaches the statements where I use the library. It spawns an error that it could not find the assembly or file 'ICSharpCode.SharpZipLib'. When I change the file name back to ICSharpCode.SharpZipLib.dll the application works noramally. So, is there any way to change the file name. Also, am I allowed to change it without violating the license (I am going to use it in a commercial application). Thanks.

  • Git to svn: Adding commit date to log messages

    - by Arnauld VM
    How should I do to have the author (or committer) name/date added to the log message when "dcommitting" to svn? For example, if the log message in Git is: This is a nice modif I'd like to have the message in svn be something like: This is a nice modif ----- Author: John Doo <[email protected] 2010-06-10 12:38:22 Committer: Nice Guy <[email protected] 2010-06-10 14:05:42 (Note that I'm mainly interested in the date, since I already mapped svn users in .svn-authors) Any simple way? Hook needed? Other suggestion? (See also: http://article.gmane.org/gmane.comp.version-control.git/148861) Thank you in advance. Yours faithfully, -- Arnauld Van Muysewinkel

  • Why does Perl's DBI complain about "failed: ERROR OCIEnvNlsCreate" when I try to connect to Oracle 1

    - by John
    I am getting the following error connecting to an Oracle 11g database using a simple Perl script: failed: ERROR OCIEnvNlsCreate. Check ORACLE_HOME (Linux) env var or PATH (Windows) and or NLS settings, permissions, etc. at The script is as follows: #!/usr/local/bin/perl use strict; use DBI; if ($#ARGV < 3) { print "Usage: perl testDbAccess.pl dataBaseUser dataBasePassword SID dataBasePort\n"; exit 0; } my ($user, $pwd, $sid, $port) = @ARGV; my $host = `hostname`; my $dbh; my $sth; my $dbname = "dbi:Oracle:HOST=$host;SID=$sid;PORT=$port"; openDbConnection(); closeDbConnection(); sub openDbConnection() { $dbh = DBI->connect ($dbname, $user ,$pwd , { RaiseError => 1}) || die "Database connection not made: $DBI::errstr"; } sub closeDbConnection() { #$sth->finish(); $dbh->disconnect(); } Anyone seen this problem before?

  • XML Schema for a .NET type that inherits and implements

    - by John Ruiz
    Hi, Please consider the following three .NET types: I have an interface, an abstract class, and a concrete class. My question is how to write the XML Schema to include the properties from the interface and from the abstract class. public interface IStartable { bool RequiresKey { get; set; } void Start(object key); } public abstract class Vehicle { uint WheelCount { get; set; } } public class Car : Vehicle, IStartable { public bool RequiresKey { get; set; } public string Make { get; set; } publilc string Model { get; set; } public Car() {} public void Start(object key) { // start car with key } } I don't know how to complete this schema: <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="cars" xmlns="cars" xmlns:c="cars"> <!-- How do I get car to have vehicle's wheelcount AND IStartable's RequiresKey? --> <xs:element name="Car" type="c:Car" /> <xs:complexType name="Car"> <xs:complexContent> <xs:extension base="c:Vehicle"> <xs:group ref=c:CarGroup" /> </xs:extension> </xs:complexContent> </xs:complexType> <xs:group name="CarGroup"> <xs:sequence> <xs:element name="Make" type="xs:token" /> <xs:element name="Model" type="xs:token" /> </xs:sequence> </xs:group> <xs:complexType name="Vehicle"> <xs:sequence> <xs:element name="WheelCount" type="xs:unsignedInt" /> </xs:sequence> </xs:complexType> <xs:complexType name="IStartable"> <xs:sequence> <xs:element name="RequiresKey" type="xs:boolean" /> </xs:sequence> </xs:complexType> </xs:schema>

  • Using NSURLRequest+NSURLConnection seems overkill for a webcall with no data return

    - by Spectravideo328
    All, This might seems very straightforward but I have already gone through the URL loading system program guide and the various NSURL.... classes and not found my answer. I am just trying to do a simple call from the app to a website to reserve a party spot: NSString *path=[NSString stringWithFormat:@"http://www.myparty123.com/ireservedURL.asp?Nickname=%@&Seat=%i&Email=%@&Currentparty=%i",john,5432,[email protected],6598]; NSURL* reservationURL =[NSURL URLWithString:path]; NSData *call= [NSData dataWithContentsOfURL:reservationURL]; This seemed to be the simple way but I get this warning that I am not using the "call" variable. And it seems overkill to do a call using NSData where there is no data return. Yet, creating an NSURLRequest and initiating an NSURLConnection and then implementing delegates with that request seems to be overkill as well. What am I missing. Thanks KMB

  • Linq to NHibernate using Queryable.Where predicate

    - by Groo
    I am querying an SQLite database using LINQ to NHibernate. Person is an entity containing an Id and a Name: public class Person { public Guid Id { get; private set; } public string Name { get; private set; } } Let's say my db table contains a single person whose name is "John". This test works as expected: var query = from item in session.Linq<Person>() where (item.Name == "Mike") select item; // no such entity should exist Assert.IsFalse(query.Any()); but this one fails: var query = from item in session.Linq<Person>() select item; query.Where(item => item.Name == "Mike"); // following line actually returns the // "John" entry Assert.IsFalse(query.Any()); What am I missing?

  • wordpress extended_valid_elements for script tag?

    - by John
    Can someone tell me how to tell Wordpress' tinymce editor to NOT strip out script tags? I looked in wp-admin/includes/post.php and added 'extended_valid_elements'=>'script[charset|defer|language|src|type]', to the $initArray. When I do a view source on the CMS post editor, I see taht it does show up like so: <script type="text/javascript"> /* <![CDATA[ */ tinyMCEPreInit = { base : "http://dev.esolar.ca/wp-includes/js/tinymce", suffix : "", query : "ver=327-1235", mceInit : {mode:"specific_textareas", editor_selector:"theEditor", width:"100%", theme:"advanced", skin:"wp_theme", theme_advanced_buttons1:"bold,italic,strikethrough,|,bullist,numlist,blockquote,|,justifyleft,justifycenter,justifyright,|,link,unlink,wp_more,|,spellchecker,fullscreen,wp_adv", theme_advanced_buttons2:"formatselect,underline,justifyfull,forecolor,|,pastetext,pasteword,removeformat,|,charmap,|,outdent,indent,|,undo,redo,wp_help", theme_advanced_buttons3:"", theme_advanced_buttons4:"", language:"en", spellchecker_languages:"+English=en,Danish=da,Dutch=nl,Finnish=fi,French=fr,German=de,Italian=it,Polish=pl,Portuguese=pt,Spanish=es,Swedish=sv", theme_advanced_toolbar_location:"top", theme_advanced_toolbar_align:"left", theme_advanced_statusbar_location:"bottom", theme_advanced_resizing:"1", theme_advanced_resize_horizontal:"", dialog_type:"modal", relative_urls:"", remove_script_host:"", convert_urls:"", apply_source_formatting:"", remove_linebreaks:"1", gecko_spellcheck:"1", entities:"38,amp,60,lt,62,gt", accessibility_focus:"1", tabfocus_elements:"major-publishing-actions", media_strict:"", paste_remove_styles:"1", paste_remove_spans:"1", paste_strip_class_attributes:"all", wpeditimage_disable_captions:"", plugins:"safari,inlinepopups,spellchecker,paste,wordpress,media,fullscreen,wpeditimage,wpgallery,tabfocus"}, load_ext : function(url,lang){var sl=tinymce.ScriptLoader;sl.markDone(url+'/langs/'+lang+'.js');sl.markDone(url+'/langs/'+lang+'_dlg.js');} }; /* ]]> */ </script> But for some reason ,my editor still doesn't save <script> tags. What am I doing wrong?

  • Clang LLVM doesn't generate warnings in Xcode

    - by John Gallagher
    I want lots of lovely warnings when compiling. I've set my build configuration to be based on a build config file I have. When I switch to GCC 4.0, it generates all the required warnings. As soon as I change to the Clang LLVM compiler, all the warnings disappear. Every other setting is identical. What am I missing?

  • Sharing Jinja2 templates between Pylons and Django applications

    - by Joe Holloway
    I'm writing a couple of Jinja2 templates that basically implement some common grid layouts. I'd like to be able to share this 'library' of templates between a Pylons app and Django app. I've hit a minor stumbling block in that Django's template context is accessible from the "top-level" of the template, whereas Pylons wraps your context inside the thread local c (or tmpl_context) variable. Here are some analogous examples that demonstrate this. Django from django.shortcuts import render_to_response ctx = {} ctx['name'] = 'John' return render_to_response('hello.html', ctx) hello.html: Hello {{ name }} Pylons from pylons import tmpl_context as c from myapp.lib.base import render c.name = 'John' return render('hello.html') hello.html: Hello {{ c.name }} What I'm trying to do is make it so that hello.html is the same across both frameworks. One way I see to do it is by wrapping the Django render_to_response and do something like this: ctx['c'] = ctx But that just doesn't feel right. Anybody see other alternatives to this? Thanks

  • problem with fork()

    - by john
    I'm writing a shell which forks, with the parent reading the input and the child process parsing and executing it with execvp. pseudocode of main method: do{ pid = fork(); print pid; if (p<0) { error; exit; } if (p>0) { wait for child to finish; read input; } else { call function to parse input; exit; } }while condition return; what happens is that i never seem to enter the child process (pid printed is always positive, i never enter the else). however, if i don't call the parse function and just have else exit, i do correctly enter parent and child alternatingly. full code: int main(int argc, char *argv[]){ char input[500]; pid_t p; int firstrun = 1; do{ p = fork(); printf("PID: %d", p); if (p < 0) {printf("Error forking"); exit(-1);} if (p > 0){ wait(NULL); firstrun = 0; printf("\n> "); bzero(input, 500); fflush(stdout); read(0, input, 499); input[strlen(input)-1] = '\0'; } else exit(0); else { if (parse(input) != 0 && firstrun != 1) { printf("Error parsing"); exit(-1); } exit(0); } }while(strcmp(input, "exit") != 0); return 0; }

  • JTree - Issues with adding of nodes

    - by John
    Hi. Im developing a system that stores courses that participants can apply to. I'm presenting the enrollments in a JTree in the courseadministratorGUI. My problem is that, for every enrollment it's adding a new courseNode. Been trying for many hours, and hope I can now get some advice that will point me in the correct direction. Thank you. private void updateJTree() { for (Category cat : catcontrol.getAllCategoriesList()) { category = new DefaultMutableTreeNode(cat); for (Course c : ccontrol.getAllCourses()) { if (cat.getIdCategory() == c.getIdCategory()) { for (Enrollment e : econtrol.getAllEnrollments()) { if (e.getIdCourse() == c.getIdCourse()) { if (cat.getIdCategory() == c.getIdCategory() && e.getCourse().equals(c)) { root.add(category); } if (c.getIdCourse() == e.getIdCourse()) { course = new DefaultMutableTreeNode(c); category.add(course); enrollment = new DefaultMutableTreeNode(e.getParticipant().getFirstNames()); course.add(enrollment); } } } } } } jTree1.setModel(new DefaultTreeModel(root)); jTree1.addTreeSelectionListener(this); jTree1.getSelectionModel().setSelectionMode(TreeSelectionModel.SINGLE_TREE_SELECTION); }

  • Keyboard blocking my view

    - by John Smith
    I have a UIView with another UIView inside it. On the inside UIView there is a textbox which I want to fill in. When I try to fill it in the keyboard blocks my view: The UIViewController has the following containerView = [[UIView alloc] initWithFrame:[UIScreen mainScreen].bounds]; self.view=containerView; //The apropriate releases etc are further on... When I touch it, the keyboard comes up as expected, but blocks the textbox I'm trying to fill in. How can I force the view to slide up? The front view OptionsFront * fv = [[OptionsFront alloc] initWithFrame:[UIScreen mainScreen].bounds]; [containerView addSubview:frontView]; In the front view is a subview CGRect bounds = CGRectMake(0.0f, 210.0f, 280.0f, 130.0f); sv = [[UIView alloc] initWithFrame:bounds]; [self addSubview:sv]; //added to frontView In sv is a textbox near the botton: rect = CGRectMake(70.0f, 20.0f, 100.0f, 27.0f); cf = [self createTextField_Rounded:rect holder:@"+ve"]; [sv addSubview:cf]; So cf happens to be near the bottom of the page. I expected that when I select it, the whole display would move up, but the keyboard just moves up and blocks it. What can I do? Appendix: - (UITextField *)createTextField_Rounded:(CGRect) frame holder:(NSString *) ph { UITextField *returnTextField = [[UITextField alloc] initWithFrame:frame]; returnTextField.borderStyle = UITextBorderStyleRoundedRect; returnTextField.textColor = [UIColor blackColor]; returnTextField.font = [UIFont systemFontOfSize:17.0]; returnTextField.delegate = self; returnTextField.keyboardType = UIKeyboardTypeNumbersAndPunctuation; returnTextField.returnKeyType = UIReturnKeyDone; returnTextField.clearButtonMode = UITextFieldViewModeWhileEditing; return returnTextField; }

  • Is key 'chord' functionality provided by Win32/.net?

    - by John
    Several MS apps support the concept of chords, like "CTRL+X,Y" which means "holding down CTRL, press X, then Y". Is this a bespoke thing they (and other companies) implement, or is it built into any APIs? It would be nice to be able to set up event handlers or accelerators based on chords rather than write code to do it.

  • Why is the servlet request not available in the portlet API

    - by John Smith
    The portlet API deos not provide any reference to the enclosing servlet request and response objects. I know it is not the preferred model of interaction with the user, but it seems draconian to remove all access. I understand that for portlet driven interaction with the user, you want to use portlet URLs, and let the portlet container manage all the complexity. However if you have a number of portlets which are basically showing variants of the same data, it makes sense for them to be able to use the enclosing request to drive the data. We ended up using using a Liferay specific call to get the request, and it all seems to work as we wish. However I do feel the guilt. So my question really is, is there an underlying deep reason for the prohibition, or is it just to enforce the authors view of the API environment?

  • Why do compiled Haskell libraries see invalid static FFI storage?

    - by John Millikin
    I am using GHC 6.12.1, in Ubuntu 10.04 When I try to use the FFI syntax for static storage, only modules running in interpreted mode (ie GHCI) work properly. Compiled modules have invalid pointers, and do not work. I'd like to know whether anybody can reproduce the problem, whether this an error in my code or GHC, and (if the latter) whether it's a known issue. Given the following three modules: -- A.hs {-# LANGUAGE ForeignFunctionInterface #-} module A where import Foreign import Foreign.C foreign import ccall "&sys_siglist" siglist_a :: Ptr CString -- -- B.hs {-# LANGUAGE ForeignFunctionInterface #-} module B where import Foreign import Foreign.C foreign import ccall "&sys_siglist" siglist_b :: Ptr CString -- -- Main.hs {-# LANGUAGE ForeignFunctionInterface #-} module Main where import Foreign import Foreign.C import A import B foreign import ccall "&sys_siglist" siglist_main :: Ptr CString main = do putStrLn $ "siglist_a = " ++ show siglist_a putStrLn $ "siglist_b = " ++ show siglist_b putStrLn $ "siglist_main = " ++ show siglist_main peekSiglist "a " siglist_a peekSiglist "b " siglist_b peekSiglist "main" siglist_main peekSiglist name siglist = do ptr <- peekElemOff siglist 2 str <- maybePeek peekCString ptr putStrLn $ "siglist_" ++ name ++ "[2] = " ++ show str I would expect something like this output, where all pointer values identical and valid: $ runhaskell Main.hs siglist_a = 0x00007f53a948fe00 siglist_b = 0x00007f53a948fe00 siglist_main = 0x00007f53a948fe00 siglist_a [2] = Just "Interrupt" siglist_b [2] = Just "Interrupt" siglist_main[2] = Just "Interrupt" However, if I compile A.hs (with ghc -c A.hs), then the output changes to: $ runhaskell Main.hs siglist_a = 0x0000000040378918 siglist_b = 0x00007fe7c029ce00 siglist_main = 0x00007fe7c029ce00 siglist_a [2] = Nothing siglist_b [2] = Just "Interrupt" siglist_main[2] = Just "Interrupt"
