  • Needs clarification on C# Flags

    - by Jojo
    Hi guys, i have this code: [Flags] public enum MyUriType { ForParse, ForDownload, Unknown } and then: MyUriType uriType = MyUriType.ForDownload; but, I was wondering why this returns true: if ((uriType & MyUriType.ForParse) == MyUriType.ForParse) When it is not set in the second code group. Please advise.

  • Code golf - hex to (raw) binary conversion

    - by Alnitak
    In response to this question asking about hex to (raw) binary conversion, a comment suggested that it could be solved in "5-10 lines of C, or any other language." I'm sure that for (some) scripting languages that could be achieved, and would like to see how. Can we prove that comment true, for C, too? NB: this doesn't mean hex to ASCII binary - specifically the output should be a raw octet stream corresponding to the input ASCII hex. Also, the input parser should skip/ignore white space. edit (by Brian Campbell) May I propose the following rules, for consistency? Feel free to edit or delete these if you don't think these are helpful, but I think that since there has been some discussion of how certain cases should work, some clarification would be helpful. The program must read from stdin and write to stdout (we could also allow reading from and writing to files passed in on the command line, but I can't imagine that would be shorter in any language than stdin and stdout) The program must use only packages included with your base, standard language distribution. In the case of C/C++, this means their respective standard libraries, and not POSIX. The program must compile or run without any special options passed to the compiler or interpreter (so, 'gcc myprog.c' or 'python myprog.py' or 'ruby myprog.rb' are OK, while 'ruby -rscanf myprog.rb' is not allowed; requiring/importing modules counts against your character count). The program should read integer bytes represented by pairs of adjacent hexadecimal digits (upper, lower, or mixed case), optionally separated by whitespace, and write the corresponding bytes to output. Each pair of hexadecimal digits is written with most significant nibble first. The behavior of the program on invalid input (characters besides [a-fA-F \t\r\n], spaces separating the two characters in an individual byte, an odd number of hex digits in the input) is undefined; any behavior (other than actively damaging the user's computer or something) on bad input is acceptable (throwing an error, stopping output, ignoring bad characters, treating a single character as the value of one byte, are all OK) The program may write no additional bytes to output. Code is scored by fewest total bytes in the source file. (Or, if we wanted to be more true to the original challenge, the score would be based on lowest number of lines of code; I would impose an 80 character limit per line in that case, since otherwise you'd get a bunch of ties for 1 line).

  • YUI dialog - what's the equivalent of postdata when using "form" (not ('async")

    - by jamesmoorecode
    I'm creating a dialog with YAHOO.widget.Dialog. The dialog is fired off by clicking on a link, and the function the link uses specifies parameters that finally get added to a postdata option like so: var myDialog = new YAHOO.widget.Dialog("myDialog", { fixedcenter: true, // postmethod: "form", postdata: propString }); This works just fine, but now I need to do the same thing but using "form" instead of "async" - and there's no postdata for form submissions. What's the right way to do this? (YUI 2.7.0)

  • What is the best way to handle my softwares licenses?

    - by Sergio Tapia
    By best I mean more time tested, easier to implement and easier for the users to work with. I do not want my licensing crap to interfere with their work. I was thinking of launching a WCF service that check with my license DB if it's a valid license and if it is, send a True. If the returned response is False, then shut down the program after telling them to fix their license. Do you think this is a good way to handle it?

  • HTTPS intercept

    - by Adrian
    I don't know much about SSL, but I've read something and I was wondering if it's possible to intercept the communication between client and server (for example, a company can monitor employees data transfer?). I thought it was a difficult task, but it looks like that it is very simple. When a client requests a https connection the router can be instructed to intercept the key exchange and send to the server and the client it's own public keys (further it can encode/decode the hole traffic). Is it true, or I'm misunderstanding something?

  • JPA Inheritance and Relations - Clarification question

    - by Michael
    Here the scenario: I have a unidirectional 1:N Relation from Person Entity to Address Entity. And a bidirectional 1:N Relation from User Entity to Vehicle Entity. Here is the Address class: @Entity public class Address implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.AUTO) privat Long int ... The Vehicles Class: @Entity public class Vehicle implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @ManyToOne private User owner; ... @PreRemove protected void preRemove() { //this.owner.removeVehicle(this); } public Vehicle(User owner) { this.owner = owner; ... The Person Class: @Entity @Inheritance(strategy = InheritanceType.JOINED) @DiscriminatorColumn(name="PERSON_TYP") public class Person implements Serializable { @Id protected String username; @OneToMany(cascade = CascadeType.ALL, orphanRemoval=true) @JoinTable(name = "USER_ADDRESS", joinColumns = @JoinColumn(name = "USERNAME"), inverseJoinColumns = @JoinColumn(name = "ADDRESS_ID")) protected List<Address> addresses; ... @PreRemove protected void prePersonRemove(){ this.addresses = null; } ... The User Class which is inherited from the Person class: @Entity @Table(name = "Users") @DiscriminatorValue("USER") public class User extends Person { @OneToMany(mappedBy = "owner", cascade = {CascadeType.PERSIST, CascadeType.REMOVE}) private List<Vehicle> vehicles; ... When I try to delete a User who has an address I have to use orphanremoval=true on the corresponding relation (see above) and the preRemove function where the address List is set to null. Otherwise (no orphanremoval and adress list not set to null) a foreign key contraint fails. When i try to delete a user who has an vehicle a concurrent Acces Exception is thrown when do not uncomment the "this.owner.removeVehicle(this);" in the preRemove Function of the vehicle. The thing i do not understand is that before i used this inheritance there was only a User class which had all relations: @Entity @Table(name = "Users") public class User implements Serializable { @Id protected String username; @OneToMany(mappedBy = "owner", cascade = {CascadeType.PERSIST, CascadeType.REMOVE}) private List<Vehicle> vehicles; @OneToMany(cascade = CascadeType.ALL) @JoinTable(name = "USER_ADDRESS", joinColumns = @JoinColumn(name = "USERNAME") inverseJoinColumns = @JoinColumn(name = "ADDRESS_ID")) ptivate List<Address> addresses; ... No orphanremoval, and the vehicle class has used the uncommented statement above in its preRemove function. And - I could delte a user who has an address and i could delte a user who has a vehicle. So why doesn't everything work without changes when i use inheritance? I use JPA 2.0, EclipseLink 2.0.2, MySQL 5.1.x and Netbeans 6.8

  • Asp Dot Net : IHttpModule + m_context.Server.Transfer = session state error

    - by tinky05
    I have an IHttpModule that implements IRequiresSessionState. The session state is at "on" on the page directive and I also added it to the web.config. In the method "OnBeginRequest" in the IHttpModule, I make a Server.Transfer but I get the error : Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. When I access the page directly or with a Response.Redirect, there is no error. Any idea?

  • Getting a visitors Facebook page

    - by Mr Carl
    Hey guys, this is more of a question out of curiosity, but is it possible to get somebody's Facebook page after they have visited your site? Was thinking maybe a chain of lookup stuff could be used starting with an IP to eventually perhaps get a name and thus that person's Facebook page. I have also heard you can read somebody's web history, is this true?

  • How to retain canvas state and use it in onDraw() method

    - by marqss
    I want to make a measure tape component for my app. It should look something like this with values from 0cm to 1000cm: Initially I created long bitmap image with repeated tape background. I drew that image to canvas in onDraw() method of my TapeView (extended ImageView). Then I drew a set of numbers with drawText() on top of the canvas. public TapeView(Context context, AttributeSet attrs){ ImageView imageView = new ImageView(mContext); LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.FILL_PARENT); imageView.setLayoutParams(params); mBitmap = createTapeBitmap(); imageView.setImageBitmap(mBitmap); this.addView(imageView); } private Bitmap createTapeBitmap(){ Bitmap mBitmap = Bitmap.createBitmap(5000, 100, Config.ARGB_8888); //size of the tape Bitmap tape = BitmapFactory.decodeResource(getResources(),R.drawable.tape);//the image size is 100x100px Bitmap scaledTape = Bitmap.createScaledBitmap(tape, 100, 100, false); Canvas c = new Canvas(mBitmap); Paint paint = new Paint(); paint.setColor(Color.WHITE); paint.setFakeBoldText(true); paint.setAntiAlias(true); paint.setTextSize(30); for(int i=0; i<=500; i++){ //draw background image c.drawBitmap(scaledTape,(i * 200), 0, null); //draw number in the middle of that background String text = String.valueOf(i); int textWidth = (int) paint.measureText(text); int position = (i * 100) + 100 - (textWidth / 2); c.drawText(text, position, 20, paint); } return mBitmap; } Finally I added this view to HorizontalScrollView. At the beginning everything worked beautifully but I realised that the app uses a Lot of memory and sometimes crashed with OutOfMemory exception. It was obvious because a size of the bitmap image was ~4mb! In order to increase the performance, instead of creating the bitmap I use Drawable (with the yellow tape strip) and set the tile mode to REPEAT: setTileModeX(TileMode.REPEAT); The view now is very light but I cannot figure out how to add numbers. There are too many of them to redraw them each time the onDraw method is called. Is there any way that I can draw these numbers on canvas and then save that canvas so it can be reused in onDraw() method?

  • Dojo and Ajax - rendering widgets

    - by Michael Merchant
    I'm trying to load content into a Dojo content pane in a specific html tag and not replace the entire content pane. The html I'm loading includes a markup defined widget that I'd like to have rendered when the new row is loaded. So, I have a table that is being dynamically filled via ajax,ie: <body> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/dojo/1.5/dojo/dojo.xd.js" djConfig="parseOnLoad: true, isDebug:true"></script> <div id="table-pane" dojoType="dijit.layout.ContentPane"> <table class="test"> <tbody> <tr><td>Name</td><td>Year</td><td>Age</td></tr> <tr> <td><span dojoType="dijit.InlineEditBox" editor="dijit.form.Textarea">Mike</span> </td> <td>2010</td> <td>12</td> </tr> </tbody> </table> </div> </body> <script> var html ='<tr><td><span dojoType="dijit.InlineEditBox" editor="dijit.form.Textarea">John</span></td><td>2011</td><td>22</td></tr>'; dojo.require("dijit.layout.ContentPane"); dojo.require("dijit.InlineEditBox"); dojo.require("dijit.form.Textarea"); dojo.addOnLoad(function(){ pane = dijit.byId("table-pane"); add_elem(); }); function add_elem(){ var node = $(".test tr:last"); node.after(html); dojo.addOnLoad(function(){ //Here I want to initiate any widgets that haven't been initiated pane.buildRendering(); }); }</script> How do I render the Dojo widget in the new table row?

  • How to change X and Y of a button

    - by Driss Zouak
    I'm using MonoTouch. When I rotate to LandscapeRight/Left I want to change the location of some of my buttons but I'm not having any success. I'm replacing the button.Bounds with a new rectangleF and setting that value in the WillRotate, but that's not working. I am returning true in my ShouldAutorotateToInterfaceOrientation handler. In principal what I'm trying to do is allow as much as possible to automatically rotate but then fix a couple of buttons that end up in a bad place.

  • jquery ie6 issue swaping videos through hide/show while playing.

    - by user217181
    So my code is: Click the link show the div. I'm using the jquery flash embed object. $(document).ready( function() { $('a.overview').click( function() { $('#overview').show(); // show div.contact $('#evaulting').hide(); // hide div.contact $('#his').hide(); // hide div.contact }); }); $(document).ready( function() { $('a.evaulting').click( function() { $('#evaulting').show(); // show div.contact $('#overview').hide(); // hide div.contact $('#his').hide(); // hide div.contact }); }); <div id="overview" style="display:none"> <ul> <li rel="play-norelated.swf:680:480:true:ffffff" class="flash-replaced"> <embed width="680" height="480" type="application/x-shockwave-flash" src="play-norelated.swf" pluginspage="http://www.adobe.com/go/getflashplayer" flashvars="playVideo=ent_web_480x" bgcolor="ffffff" /> <div class="alt"><h1>To Play Iron Mountain Videos - You will need to upgrade your Flash Player</h1> <p><a href="http://www.adobe.com/go/getflashplayer"><img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player" /></a></p></div> </li> </ul> </div> <div id="evaulting" style="display:none"> <ul> <li rel="play-norelated.swf:680:480:true:ffffff" class="flash-replaced"> <embed width="680" height="480" type="application/x-shockwave-flash" src="play-norelated.swf" pluginspage="http://www.adobe.com/go/getflashplayer" flashvars="playVideo=evaulting_web_480x" bgcolor="ffffff" /> <div class="alt"><h1>To Play Iron Mountain Video's - You will need to upgrade your Flash Player</h1> <p><a href="http://www.adobe.com/go/getflashplayer"><img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player" /></a></p></div> </li> </ul> </div> When I repeat this code and get the second video to load on click. It works in all browsers. The only issue I'm running into is that in IE6 the video keeps playing and in other browsers it stops the video your watching and loads the one you clicked on. I looked into using the .remove object or the .append to a div, but I can't seem to get that to work and if it does work will it play nice with IE6. Try it out and maybe solve my issues.

  • Selecting the contents of an ASP.NET TextBox in an UpdatePanel after a partial page postback

    - by Scott Mitchell
    I am having problems selecting the text within a TextBox in an UpdatePanel. Consider a very simple page that contains a single UpdatePanel. Within that UpdatePanel there are two Web controls: A DropDownList with three statically-defined list items, whose AutoPostBack property is set to True, and A TextBox Web control The DropDownList has a server-side event handler for its SelectedIndexChanged event, and in that event handler there's two lines of code: TextBox1.Text = "Whatever"; ScriptManager.RegisterStartupScript(this, this.GetType(), "Select-" + TextBox1.ClientID, string.Format("document.getElementById('{0}').select();", TextBox1.ClientID), true); The idea is that whenever a user chooses and item from the DropDownList there is a partial page postback, at which point the TextBox's Text property is set and selected (via the injected JavaScript). Unfortunately, this doesn't work as-is. (I have also tried putting the script in the pageLoad function with no luck, as in: ScriptManager.RegisterStartupScript(..., "function pageLoad() { ... my script ... }");) What happens is the code runs, but something else on the page receives focus at the conclusion of the partial page postback, causing the TextBox's text to be unselected. I can "fix" this by using JavaScript's setTimeout to delay the execution of my JavaScript code. For instance, if I update the emitted JavaScript to the following: setTimeout("document.getElementById('{0}').select();", 111); It "works." I put works in quotes because it works for this simple page on my computer. In a more complex page on a slower computer with more markup getting passed between the client and server on the partial page postback, I have to up the timeout to over a second to get it to work. I would hope that there is a more foolproof way to achieve this. Rather than saying, "Delay for X milliseconds," it would be ideal to say, "Run this when you're not going to steal the focus." What's perplexing is that the .Focus() method works beautifully. That is, if I scrap my JavaScript and replace it with a call to TextBox1.Focus(); then the TextBox receives focus (although the text is not selected). I've examined the contents of MicrosoftAjaxWebForms.js and see that the focus is set after the registered scripts run, but I'm my JavaScript skills are not strong enough to decode what all is happening here and why the selected text is unselected between the time it is selected and the end of the partial page postback. I've also tried using Firebug's JavaScript debugger and see that when my script runs the TextBox's text is selected. As I continue to step through it the text remains selected, but then after stepping off the last line of script (apparently) it all of the sudden gets unselected. Any ideas? I am pulling my hair out. Thanks in advance...

  • unable to capture picture using camera in j2me polish?

    - by SIVAKUMAR.J
    I'm, developing a mobile app in j2me.Now im converting it into j2me polish. In my app I capture a picture using camera in mobile phone. It works fine in j2me. But it does not work fine in j2me polish. I cannot resolve it. The code snippet given below public class VideoCanvas extends Canvas { // private VideoMIDlet midlet; // Form frm Form frm=null; public VideoCanvas(VideoControl videoControl) { int width = getWidth(); int height = getHeight(); // this.midlet = midlet; //videoControl.initDisplayMode(VideoControl.USE_DIRECT_VIDEO, this); //Canvas canvas = StyleSheet.currentScreen; //canvas = MasterCanvas.instance; videoControl.initDisplayMode( VideoControl.USE_DIRECT_VIDEO,this); try { videoControl.setDisplayLocation(2, 2); videoControl.setDisplaySize(width - 4, height - 4); } catch (MediaException me) {} videoControl.setVisible(true); } public VideoCanvas(VideoControl videoControl,Form ff) { frm=ff; int width = getWidth(); int height = getHeight(); // this.midlet = midlet; Ticker ticker=new Ticker("B4 video controll init"); frm.setTicker(ticker); //Canvas canvas = StyleSheet.currentScreen; videoControl.initDisplayMode(VideoControl.USE_DIRECT_VIDEO,this); ticker=new Ticker("after video controll init"); frm.setTicker(ticker); try { videoControl.setDisplayLocation(2, 2); videoControl.setDisplaySize(width - 4, height - 4); } catch (MediaException me) {} videoControl.setVisible(true); ticker=new Ticker("Device not supported"); frm.setTicker(ticker); } public void paint(Graphics g) { int width = getWidth(); int height = getHeight(); g.setColor(0x00ff00); g.drawRect(0, 0, width - 1, height - 1); g.drawRect(1, 1, width - 3, height - 3); } } In normal j2me the above code works correctly. But in j2me polish videoControl.initDisplayMode(VideoControl.USE_DIRECT_VIDEO,this) here this refers to VideoCanvas (which extends from javax.microedition.lcdui.Canvas). But it throws an "IllegalArgumentException - container should be canvas" like that. How to solve the issue?
