• How to run Jquery constructor from own function?

  - by Invidian

  I need to create a function which will returning jQuery.Color object and i have no idea how to do it. Here is code example function newcolor () { var obj = new $.Color( 'rgb(0,0,0)' ); return obj;} var foo = newcolor(); foo.red(); Edit: My full code: function my (element,a,b,c){ //class my this.target = $(elem); this.new_color = function (a,b,c) { return new $.Color( 'rgb('+a+','+b+','+c+')'); } this.base_color = new_color (a,b,c); this.colorize = function () ( this.target.css({ background-color: new_color }); } var div = new My($('foo'),0,0,0); div.new_color(255,255,255); div.colorize(); My goal is to create class which can hold jquery element and operate on it. Now I'm stuck on returning $.Color().

• DriverManager always returns my custom driver regardless of the connection URL

  - by JGB146

  I am writing a driver to act as a wrapper around two separate MySQL connections (to distributed databases). Basically, the goal is to enable interaction with my driver for all applications instead of requiring the application to sort out which database holds the desired data. Most of the code for this is in place, but I'm having a problem in that when I attempt to create connections via the MySQL Driver, the DriverManager is returning an instance of my driver instead of the MySQL Driver. I'd appreciate any tips on what could be causing this and what could be done to fix it! Below is a few relevant snippets of code. I can provide more, but there's a lot, so I'd need to know what else you want to see. First, from MyDriver.java: public MyDriver() throws SQLException { DriverManager.registerDriver(this); } public Connection connect(String url, Properties info) throws SQLException { try { return new MyConnection(info); } catch (Exception e) { return null; } } public boolean acceptsURL(String url) throws SQLException { if (url.contains("jdbc:jgb://")) { return true; } return false; } It is my understanding that this acceptsURL function will dictate whether or not the DriverManager deems my driver a suitable fit for a given URL. Hence it should only be passing connections from my driver if the URL contains "jdbc:jgb://" right? Here's code from MyConnection.java: Connection c1 = null; Connection c2 = null; /** *Constructors */ public DDBSConnection (Properties info) throws SQLException, Exception { info.list(System.out); //included for testing Class.forName("com.mysql.jdbc.Driver").newInstance(); String url1 = "jdbc:mysql://server1.com/jgb"; String url2 = "jdbc:mysql://server2.com/jgb"; this.c1 = DriverManager.getConnection( url1, info.getProperty("username"), info.getProperty("password")); this.c2 = DriverManager.getConnection( url2, info.getProperty("username"), info.getProperty("password")); } And this tells me two things. First, the info.list() call confirms that the correct user and password are being sent. Second, because we enter an infinite loop, we see that the DriverManager is providing new instances of my connection as matches for the mysql URLs instead of the desired mysql driver/connection. FWIW, I have separately tested implementations that go straight to the mysql driver using this exact syntax (al beit only one at a time), and was able to successfully interact with each database individually from a test application outside of my driver.

• Is it possible to control the destination folder when checking out a project from VSS 2005?

  - by swolff1978

  We are currently using VSS 2005 for source control - and please let me start by saying, I've read a lot of posts on Stackoverflow and I realize VSS is the devil. That being said... its what we have to work with now and I have a question about the checkout process. We have the code organized in a certain hierarchy on the vss server, but when we do a checkout we don't need that same hierarchy on our machines. Is there a way to control how visual studio 2008 and vss 2005 create the checkout destination folder so that I don't end up with the code being 9 folders deep on MY machine?

• How to Extract Properties for Refactoring

  - by Ngu Soon Hui

  I have this property public List<PointK> LineList {get;set;} Where PointK consists of the following structure: string Mark{get;set;} double X{get;set;} doible Y{get;set;} Now, I have the following code: private static Dictionary<string , double > GetY(List<PointK> points) { var invertedDictResult = new Dictionary<string, double>(); foreach (var point in points) { if (!invertedDictResult.ContainsKey(point.Mark)) { invertedDictResult.Add(point .Mark, Math.Round(point.Y, 4)); } } return invertedDictResult; } private static Dictionary<string , double > GetX(List<PointK> points) { var invertedDictResult = new Dictionary<string, double>(); foreach (var point in points) { if (!invertedDictResult.ContainsKey(point.Mark)) { invertedDictResult.Add(point .Mark, Math.Round(point.X, 4)); } } return invertedDictResult; } How to restructure the above code?

• serving files using django - is this a security vulnerability

  - by Tom Tom

  I'm using the following code to serve uploaded files from a login secured view in a django app. Do you think that there is a security vulnerability in this code? I'm a bit concerned about that the user could place arbitrary strings in the url after the upload/ and this is directly mapped to the local filesystem. Actually I don't think that it is a vulnerability issue, since the access to the filesystem is restricted to the files in the folder defined with the UPLOAD_LOCATION setting. UPLOAD_LOCATION = is set to a not publicly available folder on the webserver url(r'^upload/(?P<file_url>[/,.,\s,_,\-,\w]+)', 'aeon_infrastructure.views.serve_upload_files', name='project_detail'), @login_required def serve_upload_files(request, file_url): import os.path import mimetypes mimetypes.init() try: file_path = settings.UPLOAD_LOCATION + '/' + file_url fsock = open(file_path,"r") file_name = os.path.basename(file_path) file_size = os.path.getsize(file_path) print "file size is: " + str(file_size) mime_type_guess = mimetypes.guess_type(file_name) if mime_type_guess is not None: response = HttpResponse(fsock, mimetype=mime_type_guess[0]) response['Content-Disposition'] = 'attachment; filename=' + file_name #response.write(file) except IOError: response = HttpResponseNotFound() return response

• Getting the height of text to know fill height as in TCPDF

  - by sami

  I'm trying to go through the code of TCPDF to understand how it calculates the height of the text to be rendered, but it's too much for me to handle without asking. What I want to know: in the PDF from example 5 http://www.tcpdf.org/examples/example_005.pdf it gives the cell a yellow background. I'm guessing that at the basic level, it first draws a box with this fill color, then adds the text, so what method is it calling to get the height of the text to know the height of the box to fill? Anyone knows how to trace this, because doing it by hand and looking through the code isn't working at all for me.

• Problem implementing sorting algorithm in C with an array of structs

  - by dilog

  Well here is my little problem, first my code: struct alumn { char name[100]; char lastname[100]; int par; int nota; }; typedef struct alumn alumn; int bubble(alumn **arr, int length) { int i,j; alumn *temp; for (i=0; i<=length-2; i++) { for (j=i+1; j<=length-1;j++) { if ((*arr)[i].nota > (*arr)[j].nota) { temp = arr[i]; arr[i] = arr[j]; arr[j] = temp; } } } } int main(int argc, char **argv) { alumn *alumns; ... here goes some other code ... bubble(&alumns,totalAlumns); return 0; } My problem is that this algorith is not sorting anything. I'm having a hard time doing the swap, i tried everything but nothing works :( . Any help??? struct alumn { char name[100]; char lastname[100]; int par; int nota; }; typedef struct alumn alumn; int bubble(alumn **arr, int length) { int i,j; alumn *temp; for (i=0; i<=length-2; i++) { for (j=i+1; j<=length-1;j++) { if ((*arr)[i].nota > (*arr)[j].nota) { temp = arr[i]; arr[i] = arr[j]; arr[j] = temp; } } } } int main(int argc, char **argv) { alumn *alumns; ... here goes some other code ... bubble(&alumns,totalAlumns); return 0; } My problem is that this algorith is not sorting anything.

• Call a macro every time any method is called - Objective C

  - by Jacob Relkin

  Hi, I wrote a debug macro that prints to the console the passed-in string whenever the global kDebug flag == YES. I need to print out the name of a method and it's classname whenever any method is called. That works fine when i painstakingly go through every method and write the name of the class and the method in a string. Is there any special handler that gets called when any method in Objective-C is called, and if so, is there a way i can somehow override it to call my debug macro?? The entire purpose of this is so that I don't have to go through every method in my code and hand-code the method signature in the debug macro call. Thanks

• Compilers behave differently with a null parameter of a generic method

  - by Eyal Schneider

  The following code compiles perfectly with Eclipse, but fails to compile with javac: public class HowBizarre { public static <P extends Number, T extends P> void doIt(P value) { } public static void main(String[] args) { doIt(null); } } I simplified the code, so T is not used at all now. Still, I don't see a reason for the error. For some reason javac decides that T stands for Object, and then complains that Object does not conform to the bounds of T (which is true): HowBizarre.java:6: incompatible types; inferred type argument(s) java.lang.Number,java.lang.Object do not conform to bounds of type variable (s) P,T found : <P,T>void required: void doIt(null); ^ Note that if I replace the null parameter with a non-null value, it compiles fine. Which of the compilers behaves correctly and why? Is this a bug of one of them?

• Why does my program crash when given negative values?

  - by Wayfarer

  Alright, I am very confused, so I hope you friends can help me out. I'm working on a project using Cocos2D, the most recent version (.99 RC 1). I make some player objects and some buttons to change the object's life. But the weird thing is, the code crashes when I try to change their life by -5. Or any negative value for that matter, besides -1. NSMutableArray *lifeButtons = [[NSMutableArray alloc] init]; CCTexture2D *buttonTexture = [[CCTextureCache sharedTextureCache] addImage:@"Button.png"]; LifeChangeButtons *button = nil; //top left button = [LifeChangeButtons lifeButton:buttonTexture ]; button.position = CGPointMake(50 , size.height - 30); [button buttonText:-5]; [lifeButtons addObject:button]; //top right button = [LifeChangeButtons lifeButton:buttonTexture ]; button.position = CGPointMake(size.width - 50 , size.height - 30); [button buttonText:1]; [lifeButtons addObject:button]; //bottom left button = [LifeChangeButtons lifeButton:buttonTexture ]; button.position = CGPointMake(50 , 30); [button buttonText:5]; [lifeButtons addObject:button]; //bottom right button = [LifeChangeButtons lifeButton:buttonTexture ]; button.position = CGPointMake(size.width - 50 , 30); [button buttonText:-1]; [lifeButtons addObject:button]; for (LifeChangeButtons *theButton in lifeButtons) { [self addChild:theButton]; } This is the code that makes the buttons. It simply makes 4 buttons, puts them in each corner of the screen (size is the screen) and adds their life change ability, 1,-1,5, or -5. It adds them to the array and then goes through the array at the end and adds all of them to the screen. This works fine. Here is my code for the button class: (header file) // // LifeChangeButtons.h // Coco2dTest2 // // Created by Ethan Mick on 3/14/10. // Copyright 2010 Wayfarer. All rights reserved. // #import "cocos2d.h" @interface LifeChangeButtons : CCSprite <CCTargetedTouchDelegate> { NSNumber *lifeChange; } @property (nonatomic, readonly) CGRect rect; @property (nonatomic, retain) NSNumber *lifeChange; + (id)lifeButton:(CCTexture2D *)texture; - (void)buttonText:(int)number; @end Implementation file: // // LifeChangeButtons.m // Coco2dTest2 // // Created by Ethan Mick on 3/14/10. // Copyright 2010 Wayfarer.

"); //this is where we change the life to each selected player NSLog(@"Test1"); NSMutableArray *tempArray = [[[UIApplication sharedApplication] delegate] selectedPlayerObjects]; NSLog(@"Test2"); for (CustomCCNode *aPlayer in tempArray) { NSLog(@"we change the life by %d.", [lifeChange intValue]); [aPlayer changeLife:[lifeChange intValue]]; } NSLog(@"Test3"); return YES; } - (void)ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event { CGPoint touchPoint = [touch locationInView:[touch view]]; touchPoint = [[CCDirector sharedDirector] convertToGL:touchPoint]; NSLog(@"You moved in a button!"); } - (void)ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event { NSLog(@"You touched up in a button"); } @end Now, This function: - (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event Is where all the shit goes down. It works for all of the buttons except the -5 one. And then, it gets to: NSLog(@"we change the life by %d.", [lifeChange integerValue]); And it crashes at that statement. It only crashes when given anything less than -1. -1 works, but nothing smaller does. Here is the code in the CustomCCNode Class, "changeLife" that is being called. - (void)changeLife:(int)lifeChange { NSLog(@"change life in Custom Class was called"); NSLog(@"wtf is lifechange: %d", lifeChange); life += lifeChange; lifeString = [[NSString alloc] initWithFormat:@"%d",life]; [text setString:lifeString]; } Straight forward, but when the NSnumber is -5, it doesn't even get called, it crashes at the NSlog statement. So... what's up with that?

• Malloc to a CGPoint Pointer throwing EXC_BAD_ACCESS when accessing

  - by kdbdallas

  I am trying to use a snippet of code from a Apple programming guide, and I am getting a EXC_BAD_ACCESS when trying to pass a pointer to a function, right after doing a malloc. (For Reference: iPhone Application Programming Guide: Event Handling - Listing 3-6) The code in question is really simple: CFMutableDictionaryRef touchBeginPoints; UITouch *touch; .... CGPoint *point = (CGPoint *)CFDictionaryGetValue(touchBeginPoints, touch); if (point == NULL) { point = (CGPoint *)malloc(sizeof(CGPoint)); CFDictionarySetValue(touchBeginPoints, touch, point); } Now when the program goes into the if statement it assigns the 'output' of malloc into the point variable/pointer. Then when it tries to pass point into the CFDictionarySetValue function it crashes the application with: Program received signal: “EXC_BAD_ACCESS”. Someone suggested not doing the malloc and pass the point var/pointer as: &point, however that still gave me a EXC_BAD_ACCESS. What I am (and it looks like Apple) doing wrong??? Thanks in advance.

• Link to open in a new window, with 2 frames

  - by Kartik Rao

  I will be displaying news feeds from external websites on my website. So i need to open external links in those feeds in a new window, but give the user an option to return to my website. Basically I'm trying to replicate Google Images' technique of opening a link in a window with 2 frames - with the top frame having an option to "Remove Frame" and the bottom frame displaying the content of the link. Also, since the news feed will be dynamic, I don't want to hard-code anything. The code should be used automatically by any link appearing in the news feeds. Any ideas on how to do it?

• TileGroup does not fill the container

  - by Luo Yong

  I put a TileGroup in a BorderContainer and set the width to 100%, but the content in the TileGroup did not fill the parent container, it leaves a big chunk of blank on the right part. The code is: <s:BorderContainer width="100%" height="100%"> <s:TileGroup width="100%" requestedColumnCount="2"> <s:Button> button1 </s:Button> <s:Button> button2 </s:Button> <s:Button> button3 </s:Button> </s:TileGroup> </s:BorderContainer> and the result is like this: http://i.minus.com/iN39P7Us4cBm1.png The width is already set to 100% but it does not work. Is there any way to make the TileGroup fill the container like GridLayout does in Java swing? http://www.java2s.com/Code/JavaImages/GridLayoutPane.PNG Thank you very much.

• How to allow users to customize a DAL

  - by rsteckly

  Hi, I'm working in ASP.NET in an application where often users want to add fields or change field names. I'd like to be able to have an xml schema in place that is parsed and a dynamic object model created from it that can be accessed throughout the application. My initial reaction is that this is not realistic. I think there is flexibility about the dynamic nature of it. I think the people I'm trying to build this for wouldn't mind recompiling. Even if the app recompiled, I don't know how to abstract away enough in my code access the data to allow for users changing property names, etc. How can you write LINQ when the properties might change? In short, there's two questions here: 1) is there a way to dynamically generate an object model of the database and 2) is there a way to abstract away enough so that code accessing the database doesn't break when properties change?

• How to resize UILabel text after zooming UIScrollview zoomable

  - by netadictos

  I have an UIScrollview that is zoomable, the subview is one UIView (viewTexto) that contains an UILabel inside (messageLabel). This is the code - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollViewtmp{ return viewTexto; } -(void)scrollViewDidEndZooming:(UIScrollView *)scrollViewtmp withView:(UIView *)view atScale:(float)scale{ messageLabel.contentScaleFactor=scale; [scrollView setContentSize:CGSizeMake(scrollView.frame.size.width, messageLabel.frame.origin.y + messageLabel.frame.size.heightt)]; } With this code I can zoom, and the text is not blurry, there is no horizontal scroll but the size of the UILabel continues to be too large, so it is cut. I need that the width of the UILabel adopts to the scrollView width again as at the beginning. I have read any question about UIScrollViews in SO and having found exactly what I need.

• Embedded web server and gui framework for .NET applications

  - by Toad

  Hi, I'm looking for a framework which allows me to manage my application through a webbased GUI (using an embedded webserver) instead of winforms. Something like this: http://www.webtoolkit.eu/wt but then for .NET In my code I should be able to instantiate classes (like buttons, forms etc), and when a user browses to a given port, the app should render it as javascript/ajax etc etc. preferably, when buttons are pushed, a notification in my code should be called. this is a less specific question than another one I posted about extjs. I hope this will attract more viewers since it is more generic Thanks. Update: cassini like solutions don't fit the bill. Since the webbrowser is embedded in my application, there is no need for ASP.NET server side scripts. I would rather have the framework, call functions inside my application when things happen on the page. onButtonClicked() for instance.

• How does one use dynamic recompilation?

  - by acidzombie24

  It came to my attention some emulators and virtual machines use dynamic recompilation. How do they do that? In C i know how to call a function in ram using typecasting (although i never tried) but how does one read opcodes and generate code for it? Does the person need to have premade assembly chunks and copy/batch them together? is the assembly written in C? If so how do you find the length of the code? How do you account for system interrupts?

• Need to determine if ELMAH is logging an unhandled exception or one raised by ErrorSignal.Raise()

  - by Ronnie Overby

  I am using the Elmah Logged event in my Global.asax file to transfer users to a feedback form when an unhandled exception occurs. Sometimes I log other handled exceptions. For example: ErrorSignal.FromCurrentContext().Raise(new System.ApplicationException("Program code not found: " + Student.MostRecentApplication.ProgramCode)); // more code that should execute after logging this exception The problem I am having is that the Logged event gets fired for both unhandled and these handled, raised exceptions. Is there a way to determine, in the Logged event handler, whether the exception was raised via ErrorSignal class or was simply unhandled? Are there other Elmah events that I can take advantage of?

• Cocoa Touch - Display an Activity Indicator while loading a UITabBar View

  - by Aurum Aquila

  I have a UITabBar Application with two views that load large amounts of data from the web in their "viewWillAppear" methods. I want to show a progress bar or an activity indicator while this data is being retrieved, to make sure the user knows the app isn't frozen. I am aware that this has been asked before. I simply need some clarification on what seems to be a rather good solution. I have implimented the code in the example. The question's original asker later solved their problem, by putting the retrieval of data into another "thread". I understand the concept of threads, but I do not know how I would impliment this. With research, I have found that I need to move all of my heavy data retrieval into a background thread, as all of the UI updating occurs in the main thread. If one would be so kind as to provide an example for me, I would be very appreciative. I can provide parts of my existing code as necessary.

• Magento: How do I retrieve values from fields submitted with the payment method?

  - by Joseph

  Ok. This is getting a little frustrating. I am trying to create a custom payment module for Magento. The purpose is to use Authorize.net's CIM so that we don't have to worry so much about PCI compliance. The issue I am having is that the users need to be able to access their previous credit cards and use those for purchasing. I have the previous cards being stored in the database. They are also being displayed in the form in the checkout process. My issue comes when I click continue after selecting the payment method. How do I get the values I submitted in the form? Specifically, the value of the radio button the saved code is attached to? I am not sure what if any code is needed for me to post, so let me know if you need anything in particular. Thanks.

• Calculating a Sample Covariance Matrix for Groups with plyr

  - by John A. Ramey

  I'm going to use the sample code from http://gettinggeneticsdone.blogspot.com/2009/11/split-apply-and-combine-in-r-using-plyr.html for this example. So, first, let's copy their example data: mydata=data.frame(X1=rnorm(30), X2=rnorm(30,5,2), SNP1=c(rep("AA",10), rep("Aa",10), rep("aa",10)), SNP2=c(rep("BB",10), rep("Bb",10), rep("bb",10))) I am going to ignore SNP2 in this example and just pretend the values in SNP1 denote group membership. So then, I may want some summary statistics about each group in SNP1: "AA", "Aa", "aa". Then if I want to calculate the means for each variable, it makes sense (modifying their code slightly) to use: > ddply(mydata, c("SNP1"), function(df) data.frame(meanX1=mean(df$X1), meanX2=mean(df$X2))) SNP1 meanX1 meanX2 1 aa 0.05178028 4.812302 2 Aa 0.30586206 4.820739 3 AA -0.26862500 4.856006 But what if I want the sample covariance matrix for each group? Ideally, I would like a 3D array, where the I have the covariance matrix for each group, and the third dimension denotes the corresponding group. I tried a modified version of the previous code and got the following results that have convinced me that I'm doing something wrong. > daply(mydata, c("SNP1"), function(df) cov(cbind(df$X1, df$X2))) , , = 1 SNP1 1 2 aa 1.4961210 -0.9496134 Aa 0.8833190 -0.1640711 AA 0.9942357 -0.9955837 , , = 2 SNP1 1 2 aa -0.9496134 2.881515 Aa -0.1640711 2.466105 AA -0.9955837 4.938320 I was thinking that the dim() of the 3rd dimension would be 3, but instead, it is 2. Really this is a sliced up version of the covariance matrix for each group. If we manually compute the sample covariance matrix for aa, we get: [,1] [,2] [1,] 1.4961210 -0.9496134 [2,] -0.9496134 2.8815146 Using plyr, the following gives me what I want in list() form: > dlply(mydata, c("SNP1"), function(df) cov(cbind(df$X1, df$X2))) $aa [,1] [,2] [1,] 1.4961210 -0.9496134 [2,] -0.9496134 2.8815146 $Aa [,1] [,2] [1,] 0.8833190 -0.1640711 [2,] -0.1640711 2.4661046 $AA [,1] [,2] [1,] 0.9942357 -0.9955837 [2,] -0.9955837 4.9383196 attr(,"split_type") [1] "data.frame" attr(,"split_labels") SNP1 1 aa 2 Aa 3 AA But like I said earlier, I would really like this in a 3D array. Any thoughts on where I went wrong with daply() or suggestions? Of course, I could typecast the list from dlply() to a 3D array, but I'd rather not do this because I will be repeating this process many times in a simulation. As a side note, I found one method (http://www.mail-archive.com/[email protected]/msg86328.html) that provides the sample covariance matrix for each group, but the outputted object is bloated. Thanks in advance.

• Can I set a property on an object that is only declared on the instance type, when I don't know the

  - by WilberBeast

  Let me explain. I have a List into which I am adding various ASP.NET controls. I then wish to loop through the list and set a CssClass, however not every Control supports the property CssClass. What I would like to do is test if the underlying instance type supports the CssClass property and set it, but I'm not sure how to do the conversion prior to setting the property since I don't know the type of each Control object. I know that I can use typeof or x.GetType(), but I'm not sure how to use these to convert the controls back to the instance type in order to test for and then set the property. Actually I seem to have solved this, so I thought that I would post the code here for others. foreach (Control c in controlList) { PropertyInfo pi = c.GetType().GetProperty("CssClass"); if (pi != null) pi.SetValue(c, "desired_css_class", null); } I hope that this helps someone else as I has taken me hours to research these 2 lines of code. Cheers Steve

• Routinely sync a branch to master using git rebase

  - by m1755

  I have a Git repository with a branch that hardly ever changes (nobody else is contributing to it). It is basically the master branch with some code and files stripped out. Having this branch around makes it easy for me to package up a leaner version of my project without having to strip out the code and files manually every time. I have been using git rebase to keep this branch up to date with the master but I always get this warning when I try to push the branch after rebasing: To prevent you from losing history, non-fast-forward updates were rejected Merge the remote changes before pushing again. See the 'Note about fast-forwards' section of 'git push --help' for details. I then use git push --force and it works but I feel like this is probably bad practice. I want to keep this branch "in sync" with the master quickly and easily. Is there a better way of handling this task?

• Which distribution website should I pick for my open-source package?

  - by Frank

  I wrote an open-source software package, which I'd like to publish (using Apache 2 license). I see various options for how/where to publish/host it: Get my own domain and put it there Put it on Sourceforge Put it on Google Code Put it on Freshmeat ...? What are your experiences / recommendations? What's the current trend among software developers? My only requirements are that I ... can add my own logo on the website can put up some documentation there, get a nice URL that is easy to remember get SVN support (I would also be fine with just uploading a tarball for each new version, it just shouldn't force me to use CVS or any other version control system I'm not familiar with) and of course, the site shouldn't take ownership in the code etc. oh, and it should be free (ok, for registering my own domain I'll be willing to pay a little bit)
