  • structDelete doesn't affect the shallow copy?

    - by Travis
    I was playing around onError so I tried to create an error using a large xml document object. <cfset XMLByRef = variables.parsedXML.XMLRootElement.XMLChildElement> <cfset structDelete(variables.parsedXML, "XMLRootElement")> <cfset startXMLShortLoop = getTickCount()> <cfloop from = "1" to = "#arrayLen(variables.XMLByRef)#" index = "variables.i"> <cfoutput>#variables.XMLByRef[variables.i].id.xmltext#</cfoutput><br /> </cfloop> <cfset stopXMLShortLoop = getTickCount()> I expected to get an error because I deleted the structure I was referencing. From LiveDocs: Variable Assignment - Creates an additional reference, or alias, to the structure. Any change to the data using one variable name changes the structure that you access using the other variable name. This technique is useful when you want to add a local variable to another scope or otherwise change a variable's scope without deleting the variable from the original scope. instead I got 580df1de-3362-ca9b-b287-47795b6cdc17 25a00498-0f68-6f04-a981-56853c0844ed ... ... ... db49ed8a-0ba6-8644-124a-6d6ebda3aa52 57e57e28-e044-6119-afe2-aebffb549342 Looped 12805 times in 297 milliseconds <cfdump var = "#variables#"> Shows there's nothing in the structure, just parsedXML.xmlRoot.xmlName with the value of XMLRootElement. I also tried <cfset structDelete(variables.parsedXML.XMLRootElement, "XMLChildElement")> as well as structClear for both. More information on deleting from the xml document object. http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec22c24-78e3.html Can someone please explain my faulty logic? Thanks.

  • LINQ to SQL Could not find key member. Only fails on server.

    - by Adam Carr
    I have a scenario where I am inheriting from an abstract class in my partial linq to sql auto generated class implementation. My base abstract class has an abstract property called ID which I have flagged inside my LINQ to SQL model with the instance modifier override. This works fine locally without any issues. I have also done some development on another machine and it works fine there too (both in VS2008 and using Subversion). I am running CI with TeamCity and the build succeeds and deploys as desired. The problem is when the server tries to hit the database for the first time via the LINQ to SQL data context, it generates the following error. "Could not find key member 'Id' of key 'Id' on type 'CustomType'. The key may be wrong or the field or property on 'CustomType' has changed names." I have tried changing my configuration by not implementing the Id field in my base class but this still fails. Why does it work on both of my DEV machines but not on the server? I am using LINQ to SQL in another project that runs on this server just fine. FYI: LINQ to SQL, SQL 2008, .NET 3.5, SERVER 2008, IIS 7.0 UPDATE I have gone back and added the same table a second time in the same data model but without a base class and have then displayed the results from that table and got no errors. This tells me it has something to do with my base abstract class and the need to flag a property on one of my linq to sql model classes (that belongs to a key relationship) with the instance modifier of override. No answer to this yet but am getting closer. UPDATE I have fixed my issue by simply changing my approach to my problem but I am still interested in why this doesn't work. I created a new WinSrv2008 VPC and patched it, deployed a pre-built version of my site to it and still got the same error. I now assume the issue is like what the person said here, a dependency issue with VS2008. My question is what or what? Will install VS2008 on the VPC to see if it works after that.

  • Java: omitting a data member from the equals method.

    - by cchampion
    public class GamePiece { public GamePiece(char cLetter, int nPointValue) { m_cLetter=cLetter; m_nPointValue=nPointValue; m_nTurnPlaced=0; //has not been placed on game board yet. } public char GetLetter() {return m_cLetter;} public int GetPointValue() {return m_nPointValue;} public int GetTurnPlaced() {return m_nTurnPlaced;} public void SetTurnPlaced(int nTurnPlaced) { m_nTurnPlaced=nTurnPlaced; } @Override public boolean equals(Object obj) { /*NOTE to keep this shorter I omitted some of the null checking and instanceof stuff. */ GamePiece other = (GamePiece) obj; //not case sensitive, and I don`t think we want it to be here. if(m_cLetter != other.m_cLetter) { return false; } if(m_nPointValue != other.m_nPointValue) { return false; } /* NOTICE! m_nPointValue purposely omitted. It does not affect hashcode or equals */ return true; } @Override public int hashCode() { /* NOTICE! m_nPointValue purposely omitted. It should not affect hashcode or equals */ final int prime = 41; return prime * (prime + m_nPointValue + m_cLetter); } private char m_cLetter; private int m_nPointValue; private int m_nTurnPlaced;//turn which the game piece was placed on the game board. Does not affect equals or has code! } Consider the given piece of code. This object has been immutable until the introduction of the m_nTurnPlaced member (which can be modified by the SetTurnPlaced method, so now GamePiece becomes mutable). GamePiece is used in an ArrayList, I call contains and remove methods which both rely on the equals method to be implemented. My question is this, is it ok or common practice in Java for some members to not affect equals and hashcode? How will this affect its use in my ArrayList? What type of java Collections would it NOT be safe to use this object now that it is mutable? I've been told that you're not supposed to override equals on mutable objects because it causes some collections to behave "strangely" (I read that somewhere in the java documentation).

  • Is this PHP/MySQL login script secure?

    - by NightMICU
    Greetings, A site I designed was compromised today, working on damage control at the moment. Two user accounts, including the primary administrator, were accessed without authorization. Please take a look at the log-in script that was in use, any insight on security holes would be appreciated.

  • Getting a seg fault, having trouble with classes and variables.

    - by celestialorb
    Ok, so I'm still learning the ropes of C++ here so I apologize if this is a simple mistake. I have this class: class RunFrame : public wxFrame { public: RunFrame(); void OnKey(wxKeyEvent& keyEvent); private: // Configuration variables. const wxString *title; const wxPoint *origin; const wxSize *size; const wxColour *background; const wxColour *foreground; const wxString *placeholder; // Control variables. wxTextCtrl *command; // Event table. DECLARE_EVENT_TABLE() }; ...then in the OnKey method I have this code: void RunFrame::OnKey(wxKeyEvent& keyEvent) { // Take the key and process it. if(WXK_RETURN == keyEvent.GetKeyCode()) { bool empty = command -> IsEmpty(); } // Propogate the event through. keyEvent.Skip(); } ...but my program keeps seg faulting when it reaches the line where I attempt to call the IsEmpty method from the command variable. My question is, "Why?" In the constructor of the RunFrame class I can seemingly call methods for the command variable in the same way I'm doing so in the OnKey method...and it compiles correctly, it just seg faults on me when it attempts to execute that line. Here is the code for the constructor if necessary: RunFrame::RunFrame() : wxFrame(NULL, wxID_ANY, wxT("DEFAULT"), wxDefaultPosition, wxDefaultSize, wxBORDER_NONE) { // Create the styling constants. title = new wxString(wxT("RUN")); origin = new wxPoint(0, 0); size = new wxSize(250, 25); background = new wxColour(33, 33, 33); foreground = new wxColour(255, 255, 255); placeholder = new wxString(wxT("command")); // Set the styling for the frame. this -> SetTitle(*title); this -> SetSize(*size); // Create the panel and attach the TextControl to it. wxPanel *panel = new wxPanel(this, wxID_ANY, *origin, *size, wxBORDER_NONE); // Create the text control and attach it to the panel. command = new wxTextCtrl(panel, wxID_ANY, *placeholder, *origin, *size); // Set the styling for the text control. command -> SetBackgroundColour(*background); command -> SetForegroundColour(*foreground); // Connect the key event to the text control. command -> Connect(wxEVT_CHAR, wxKeyEventHandler(RunFrame::OnKey)); // Set the focus to the command box. command -> SetFocus(); } Thanks in advance for any help you can give!

  • Where can I find a comprehensive reference for Zen Cart variables and overrides?

    - by Angelina
    Hi everyone, I'm working with Zen Cart for a client and I'm having a bit of trouble finding a practical, concise resource that gives reference to the most common template variables and overrides. This project is fairly superficial so that is all I need - but bonus points if you find something that goes a little bit deeper. Please note that I am looking for something that is 'at a glance', like a reference card. I have already looked at several books on Zen Cart, but most of them are designed for the end user or a sysadmin at most and leave much to be desired.

  • How does one inject variables into page templates from a custom Drupal module?

    - by Michael T. Smith
    We've created a custom module for organizing and publishing our newsletter content. The issue I'm running into now -- and I'm new to theming and Drupal module development, so it could just be a knowledge issue as opposed to a Drupal issue -- is how to get each newsletter themed. At this point the URL structure of our newsletter will be: /newsletters/{newsletter-name}/{edition-name}/{issue-date} which means that we can create template files in our theme using filenames like page-newsletters-{newsletter-name}-{edition-name}.tpl.php, which is great. The one issue I'm running into is that all of the content comes through in the $content variable of the theme. I'd like to have it come through as different variables (so that I can, inside the theme, place certain content in certain areas.) Is there a proper way for doing this?

  • Optimal method to create a large string containing several variables?

    - by Runcible
    I want to create a string that contains many variables: std::string name1 = "Frank"; std::string name2 = "Joe"; std::string name3 = "Nancy"; std::string name4 = "Sherlock"; std::string sentence; sentence = name1 + " and " + name2 + " sat down with " + name3; sentence += " to play cards, while " + name4 + " played the violin."; This should produce a sentence that reads Frank and Joe sat down with Nancy to play cards, while Sherlock played the violin. My question is: What is the optimal way to accomplish this? I am concerned that constantly using the + operator is ineffecient. Is there a better way?

  • Should I call release on these cocoa objective-c variables?

    - by Andrew Arrow
    In the code below I'm making a new NSString with alloc and initializing it with the contents of some file. Because I'm calling alloc I know it's my responsibility to call release on the string when I'm done. But what about the variables "lines" and "line"? Since the method "componentsSeparatedByString" does not start with the word "new" or "create" can I assume "lines" will be autoreleased? Same question for "line" since "objectAtIndex" also does not start with "new" or "create". NSString* buffer = [[NSString alloc] initWithData:[fileManager contentsAtPath:@"/foo"] encoding:NSUTF8StringEncoding]; NSArray* lines = [buffer componentsSeparatedByString:@"\n"]; NSString* line = [lines objectAtIndex:5]; // do something with line [buffer release]; So is the code above okay? Or should I be calling "release" on lines and line too? Thanks.

  • How do I assign selected WPF datagrid row columns to variables. (VB.NET)

    - by Peter
    Hi, I have a datagrid with customer data such as ID, name, email, phone etc. When I select a row (with a button or selectionchanged) I want to store that row's columns in variables like dim email as string dim name as string email = dgCustomers.theselectedrow.theselectedcell name = dgCustomers.theselectedrow.theselectedcell If I have a datatable with only one row I know I can get column data with: dim email as string = CustomerDataTableInstance.rows(0).Item("Email") I don't know how to get the selected row number though when I have several rows and the user clicks one/uses the keyboard. The datagrid is bound to a datatable, not a class with object collections. Any help is appreciated!

Could someone shed some light on me? Many thanks.

  • How do I pass custom variables to javascript events?

    - by RoboShop
    I have a user control with a javascript function which references some controls within the user control. This user control works perfectly when there is only one instance of it, but I'm now building a page where I have two instances of the user control. In IE7, it works fine, but in FireFox, it is getting confused that there is two functions of the exact same name and signature. So on UserControl1, it'll be running the function in UserControl2 and modifying that content. I'm thinking my best solution would be to pass the clientID of the components I need TO the function instead of just directly referencing it in the function. How would I do that? The signature of the javascript function is like this function nodeClicking(sender, args) and I'm calling it in an event like this <telerik:RadTreeView runat="server" ID="OrgUnitTreeView" OnInit="TreeViewLoad" OnClientNodeClicking="**nodeClicking**" EnableViewState="true" DataTextField = "OrganisationUnitName" DataValueField = "OrganisationUnitCode" DataFieldParentID = "ParentOrganisationUnitCode" DataFieldID = "OrganisationUnitCode"> How do I add extra variables to the function signature.

  • How to use a regular expression and assign the result to variables in Android?

    - by ChengYing
    I have a string named s_Result which will be parsed from the Internet. The format may be "Distance: 2.8km (about 9 mins)", and there are 4 variables which are f_Distance, m_DistanceUnit, f_timeEst, m_timeEstUnit. My question is how to parse s_Result and assign 2.8, km, 9, mins into f_Distance, m_distanceUnit, f_timeEst and m_timeEstUnit respectively using regular expression? I tried using "\d+(\.\d+)?" in RegEx Tester and the result showed 2 matches found, but if I use "\\d+(\\.\\d+)?" in Android code, it showed no matches! Any suggestions what might be going wrong?

    Lets say I have two variables defining separate selectors, for example... var parent = $('.parent'); var child = $('.child'); And I want to create a something like the following... $(parent + child).click(); Which should be equivalent to doing this (if it was correct syntax)... $('.parent .child').click(); This may not be best practice, however I am curious if it is possible. Thanks for your help in advance.

  • How can I pass query string variables with NavigationService.Navigate?

    - by Mike Hildner
    Greetings, Searched for this, but no luck. I'm attempting to pass query string variables (and then retrieve them) in my Silverlight 4 app. First I tried this this.NavigationService.Navigate(new Uri("/LoanProductionRegion?Elvis=Alive&ImHungry=true", UriKind.Relative)); But HtmlPage.Document.QueryString doesn't pick them up because they come after the anchor (the full url looks like http://localhost:1076/Dashboard.SLTestPage.aspx#/LoanProductionRegion?Elvis=Alive&ImHungry=true). I tried to put the vars in front, such as this.NavigationService.Navigate(new Uri("?Elvis=Alive&ImHungry=true/LoanProductionRegion", UriKind.Relative)); this.NavigationService.Navigate(new Uri("/?Elvis=Alive&ImHungry=true/LoanProductionRegion", UriKind.Relative)); But both result in a "Page not found" error. Anyone know how to achieve what I'm after?

  • What is the impact/limitation of oracle select with large number of bind variables?

    - by Igal Serban
    We had our oracle server chocking during processing a select statement with close to 3500(!!) bind variables. This select is, obviously, build dynamically by code that we can't change. During the execution of this select the db server went to 100% cpu usage and our system almost halted. We know how to reproduce this problem. So we can prevent this specific condition. But I am wondering if there is a way to protect the db ( by configuration) from this type of problems.

  • Is it possible to preg replace unique variables into a string?

    - by Scarface
    What I want to do is use preg replace to replace matches within a string with a varying replacement, and I was wondering if anyone knew if that is possible in php or at least achievable by some means. For example, a string has two matches, then those matches will be replaced with two different variables. What I want are replacements to each be a unique id and I cannot figure out how this could possibly work or if php could even do this. For example if the match is 'a' and there is a sentence, 'put a smile on a person' then one 'a' will be unique id 98aksd00 and the other will be 09alkj08. I am retrieving my comments from a database so the preg replace is happening within while ($row=mysql_fetch_assoc($query)){ //preg replace If anyone could provide any insight into this, I would really appreciate it

  • How should I declare default values for instance variables in Python?

    - by int3
    Should I give my class members default values like this: class Foo: num = 1 or like this? class Foo: def __init__(self): self.num = 1 In this question I discovered that in both cases, bar = Foo() bar.num += 1 is a well-defined operation. I understand that the first method will give me a class variable while the second one will not. However, if I do not require a class variable, but only need to set a default value for my instance variables, are both methods equally good? Or one of them more 'pythonic' than the other? One thing I've noticed is that in the Django tutorial, they use the second method to declare Models. Personally I think the second method is more elegant, but I'd like to know what the 'standard' way is.

  • How can I manage command line arguements/variables for a script written in Perl?

    - by Structure
    I am trying to manage numerous arguments that are specified by a user when they execute a command. So far, I have been trying to limit my script design to manage arguments as flags that I can easily manage with Getopt::Long as follows: GetOptions ("a" => \$a, "b" => \$b); In this way I can check to see if a or b were specified and then execute the respective code/functions. However, I now have a case where the user can specify two arguments variables as follows: command -a black -b white This is fine, but I cannot come up with a good way to determine whether -a or -b is specified first. Therefore I do not know whether the argument variable is assigned to $ARGV[0] or $ARGV[1] after I have executed GetOptions ("a" => \$a, "b" => \$b);. How can I tell which variable is associated with -a and which is associated with -b in the example above?

  • Definition of variables/fields type within a constructor, how is it done?

    - by elementz
    I just had a look at Suns Java tutorial, and found something that totally confused me: Given the following example: public Bicycle(int startCadence, int startSpeed, int startGear) { gear = startGear; cadence = startCadence; speed = startSpeed; } Why is it, that the types of the variables (fields?) gear, cadence and speed do not need to be defined? I would have written it as follows: public Bicycle(int startCadence, int startSpeed, int startGear) { int gear = startGear; int cadence = startCadence; int speed = startSpeed; } What would be the actual differnce?

  • Explicitly typing variables causes compiler to think an instance of a builtin type doesn't have a pr

    - by wallacoloo
    I narrowed the causes of an AS3 compiler error 1119 down to code that looks similar to this: var test_inst:Number = 2.953; trace(test_inst); trace(test_inst.constructor); I get the error "1119: Access of possibly undefined property constructor through a reference with static type Number." Now if I omit the variable's type, I don't get that error: var test_inst = 2.953; trace(test_inst); trace(test_inst.constructor); it produces the expected output: 2.953 [class Number] So what's the deal? I like explicitly typing variables, so is there any way to solve this error other than not providing the variable's type?
