• Vimeo Desktop App OAuth

  - by Barry

  Hi Guys, I'm currently having massive trouble with Vimeo's Oauth implementation and my desktop app. My program does the following correctly. 1- Requests a Unauthorized Request Token with my key and secret and returns - a Token and a Token secret. 2- Generates a URL for the user to go to using the token which then shows our application's name and allows the user to Authorize us to use his/her account. It then shows a verifier which the user returns and puts into our app. The problem is the third step and actually exchanging the tokens for the access tokens. Basically every time we try and get them we get a "Invalid / expired token - The oauth_token passed was either not valid or has expired" I looked at the documentation and there's supposed to be a callback to a server when deployed like that which gives the user an "authorized token" but as im developing a desktop app we can't do this. So I assume the token retrieved in 1 is valid for this step. (actually it seems it is: http://vimeo.com/forums/topic:22605) So I'm wondering now am I missing something here on my actual vimeo application account now? is it treating it as a web hosted app with callbacks? all the elements are there for this to work and I've used this same component to create a twitter Oauth login in exactly the same way and it was fine. Thanks in advance, Barry

• What do I need for development for an ARM processor?

  - by claws

  Hello, I'm familiar with X86[-64] architecture & assembly. I want to start develop for an ARM processor. But unlike desktop processors, I don't have an actual ARM processor. I think I need an ARM simulator. http://www.armtutorial.com/ say An ARM assembly compiler will be required, the most accessible is the ARMulator. I thought of downloading Armulator but found from http://forums.arm.com/index.php?showtopic=13744 that Its not sold seperately. But you can download an eval of RVDS - which includes RVISS/ARMulator I've downloaded & installed RVDS but It looks very complex. I'm unable to figure out what do I need to do to write ARM assembly & run it. I want to write in assembly not in C/C++. I don't have an ARM processor. What is a good simulator? Can any one please mention in short. How to write assembly & assemble & simulate using RVDS. Please be clear? Are there any other alternative ways. I can't afford buying any kind of boards. I always learn from books rather than tutorials. I'm following these two books: ARM System Developer's Guide: Designing and Optimizing System Software (The Morgan Kaufmann Series in Computer Architecture and Design) ARM System-on-Chip Architecture (2nd Edition) Do you have any better suggestions?

• How do people know so much about programming?

  - by Luciano

  I see people in this forums with a lot of points, so I assume they know about a lot of different programming stuff. When I was young I knew about basic (commodore) and the turbo pascal (pc). Then in college I learnt about C, memory management, x86 set, loop invariants, graphs, db query optimization, oop, functional, lambda calculus, prolog, concurrency, polymorphism, newton method, simplex, backtracking, dynamic programming, heuristics, np completeness, LR, LALR, neural networks, static & dynamic typing, turing, godel, and more in between. Then in industry I started with Java several years ago and learnt about it, and its variety of frameworks, and also design patterns, architecture patterns, web development, server development, mobile development, tdd, bdd, uml, use cases, bug trackers, process management, people management if you are a tech lead, profiling, security concerns, etc. I started to forget what I learnt in college... And then there is the stuff I don't know yet, like python, .net, perl, JVM stuff like groovy or scala.. Of course Google is a must for rapid documentation access to know if a problem has been solved already and how, and to keep informed about new stuff by blogs and places like this one. It's just too much or I just have a bad memory.. how do you guys manage it?

• RegularExpression Validator doesn't display error message.

  - by Rudi Ramey

  I have a regular expression validation control initialized to validate a textbox control. I want users to be able to enter U.S. Currency values ($12,115.85 or 1500.22 etc.). I found a regular expression off of regexlib website that does the trick. The validation control seems to be working except for one crucial thing. If invalid data is entered, the validation text dispalys (a red "*" next to the textbox), but the page will still submit and the error message won't pop up... I thought that the error message is supposed to display and the page won't submit if the validation control detects invalid data. Isn't this automatic with ASP .NET? I have searched extensively on how to create validation controls, but haven't found anything different than what I am already doing. Can anyone tell me what I am doing wrong here? <asp:TextBox ID="txtActualCost" runat="server" Width="120px" CausesValidation="true"></asp:TextBox> <asp:RegularExpressionValidator ID="regExValActualCost" ControlToValidate="txtActualCost" Text="*" ValidationExpression="^\$?(\d{1,3}(\,\d{3})*|(\d+))(\.\d{2})?$" ErrorMessage="Please enter a valid currency value for 'Actual Cost'" Display="Dynamic" EnableClientScript="true" runat="server" />

• How to avoid "Illegal type in constant pool" using "ldc_w <classname>" in Jasmin?

  - by jazzdev

  I'm writing a compiler that generates Jasmin code and want to invoke a method that takes a Class as a parameter. public class CTest { public static void main(String[] args) throws Exception { java.lang.reflect.Array.newInstance(CTest.class, 0); } } So in Jasmin, I think that should be: .class public CTest2 .super java/lang/Object .method public static main([Ljava/lang/String;)V .limit stack 2 .limit locals 1 ldc_w CTest2 iconst_0 invokestatic java/lang/reflect/Array/newInstance(Ljava/lang/Class;I)Ljava/lang/Object; pop return .end method When I assemble it and run it I get: Exception in thread "main" java.lang.VerifyError: (class: CTest2, method: main signature: ([Ljava/lang/String;)V) Illegal type in constant pool Looking at the disassembled code for both CTest.class (the Java version) and CTest2.class (the Jasmin version) with "javap -c -verbose" they both appear to set up the constant pool the same way: const #2 = class #16; // CTest const #16 = Asciz CTest; 0: ldc_w #2; //class CTest const #14 = Asciz CTest2; const #17 = class #14; // CTest2 0: ldc_w #17; //class CTest2 I've fixed two bugs in Jasmin already, but I can't see what it's doing wrong when putting the class in the constant pool for "ldc_w" it puts classes in the constant pool for other instructions, like "new" and "anewarray" correctly. I've tried looking at the .class files with TraceClassVisitor in ASM, but it doesn't dump the constant pool. Any ideas what I can try next?

• Android Custom Dialog NullPointerException

  - by Kyle Hughes

  I cannot for the life of me figure out why I'm getting a NullPointerException. When a user clicks on a particular image, a dialog window is supposed to pop-up and display a larger version of said image: private OnClickListener coverListener = new OnClickListener() { public void onClick(View v) { showDialog(DIALOG_COVER); } }; DIALOG_COVER is set to = 0. The associated onCreateDialog looks like this: protected Dialog onCreateDialog(int id) { Dialog dialog; switch(id) { case DIALOG_COVER: dialog = new Dialog(mContext); dialog.setContentView(R.layout.cover_dialog); dialog.setTitle(book.getTitle()); ImageView coverLarge = (ImageView)findViewById(R.id.coverLarge); coverLarge.setImageBitmap(book.getCover()); break; default: dialog = null; } return dialog; } For reference, this is cover_dialog.xml: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/coverDialog" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp"> <ImageView android:id="@+id/coverLarge" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="fitStart" /></LinearLayout> Now, when the image previously described is clicked, the application immediately crashes and throws the following error through LogCat: 06-08 13:29:17.727: ERROR/AndroidRuntime(2220): Uncaught handler: thread main exiting due to uncaught exception 06-08 13:29:17.757: ERROR/AndroidRuntime(2220): java.lang.NullPointerException 06-08 13:29:17.757: ERROR/AndroidRuntime(2220): at org.kylehughes.android.brarian.AndroidBrarian.onCreateDialog(AndroidBrarian.java:259) The line in question refers to this line inside of onCreateDialog: coverLarge.setImageBitmap(book.getCover()); Basically, I don't get why coverLarge is null at that point. Any help would be much appreciated.

• How can CSS be applied to components from Google Closure Library?

  - by Jason

  I'm getting my feet wet with Google's Closure Library. I've created a simple page with a Select Widget, but it clearly needs some styling (element looks like plain text, and in the example below the menu items pop up beneath the button). I'm assuming the library supports styles -- how can I hook into them? Each example page in SVN seems to use its own CSS. Abbreviated example follows: <body> <div id="inputContainer"></div> <script src="closure-library-read-only/closure/goog/base.js"></script> <script> goog.require('goog.dom'); goog.require('goog.ui.Button'); goog.require('goog.ui.MenuItem'); goog.require('goog.ui.Select'); </script> <script> var inputDiv = goog.dom.$("inputContainer"); var testSelect = new goog.ui.Select("Test selector"); testSelect.addItem(new goog.ui.MenuItem("1")); testSelect.addItem(new goog.ui.MenuItem("2")); testSelect.addItem(new goog.ui.MenuItem("3")); var submitButton = new goog.ui.Button("Go"); testSelect.render(inputDiv); submitButton.render(inputDiv); </script> </body>

• passing hashes to a subroutine

  - by Vishalrix

  In one of my main( or primary) routines,I have two or more hashes. I want the subroutine foo() to recieve these possibly-multiple hashes as distinct hashes. Right now I have no preference if they go by value, or as references. I am struggling with this for the last many hours and would appreciate help, so that I dont have to leave perl for php! ( I am using mod_perl, or will be) Right now I have got some answer to my requirement, shown here From http://forums.gentoo.org/viewtopic-t-803720-start-0.html # sub: dump the hash values with the keys '1' and '3' sub dumpvals { foreach $h (@_) { print "1: $h->{1} 3: $h->{3}\n"; } } # initialize an array of anonymous hash references @arr = ({1,2,3,4}, {1,7,3,8}); # create a new hash and add the reference to the array $t{1} = 5; $t{3} = 6; push @arr, \%t; # call the sub dumpvals(@arr); I only want to extend it so that in dumpvals I could do something like this: foreach my %k ( keys @_[0]) { # use $k and @_[0], and others } The syntax is wrong, but I suppose you can tell that I am trying to get the keys of the first hash ( hash1 or h1), and iterate over them. How to do it in the latter code snippet above?

• Django access data passed to form

  - by realshadow

  Hey, I have got a choiceField in my form, where I display filtered data. To filter the data I need two arguments. The first one is not a problem, because I can take it directly from an object, but the second one is dynamically generated. Here is some code: class GroupAdd(forms.Form): def __init__(self, *args, **kwargs): self.pid = kwargs.pop('parent_id', None) super(GroupAdd, self).__init__(*args, **kwargs) parent_id = forms.IntegerField(widget=forms.HiddenInput) choices = forms.ChoiceField( choices = [ [group.node_id, group.name] for group in Objtree.objects.filter( type_id = ObjtreeTypes.objects.values_list('type_id').filter(name = 'group'), parent_id = 50 ).distinct()] + [[0, 'Add a new one'] ], widget = forms.Select( attrs = { 'id': 'group_select' } ) ) I would like to change the parent_id that is passed into the Objtree.objects.filter. As you can see I tried in the init function, as well with kwargs['initial']['parent_id'] and then calling it with self, but that doesnt work, since its out of scope... it was pretty much my last effort. I need to acccess it either trough the initial parameter or directly trough parent_id field, since it already holds its value (passed trough initial). Any help is appreciated, as I am running out of ideas.

• jackson failing to map empty array with No content to map to Object due to end of input

  - by ijabz

  I send a query to an api and map the json results to my classes using Jackson. When I get some results it works fine, but when there are no results it fails with java.io.EOFException: No content to map to Object due to end of input at org.codehaus.jackson.map.ObjectMapper._initForReading(ObjectMapper.java:2766) at org.codehaus.jackson.map.ObjectMapper._readMapAndClose(ObjectMapper.java:2709) at org.codehaus.jackson.map.ObjectMapper.readValue(ObjectMapper.java:1854) at com.jthink.discogs.query.DiscogsServerQuery.mapQuery(DiscogsServerQuery.java:382) at com.jthink.discogs.query.SearchQuery.mapQuery(SearchQuery.java:37)* But the thing is the api isn't returning nothing at all, so I dont see why it is failing. Here is the query: http://api.discogs.com/database/search?page=1&type=release&release_title=nude+and+rude+the+best+of+iggy+pop this is what I get back { "pagination": { "per_page": 50, "pages": 1, "page": 1, "urls": {}, "items": 0 }, "results": [] } and here is the top level object Im trying to map to public class Search { private Pagination pagination; private Result[] results; public Pagination getPagination() { return pagination; } public void setPagination(Pagination pagination) { this.pagination = pagination; } public Result[] getResults() { return results; } public void setResults(Result[] results) { this.results = results; } } Im guessing the problem is something to do with the results array being returned being blank, but cant see what Im doing wrong EDIT: The comment below was correct, although I usually receive { "pagination": { "per_page": 50, "pages": 1, "page": 1, "urls": {}, "items": 0 }, "results": [] } and in these cases there is no problem but sometimes I seem to just get an empty String. Now Im wondering if the problem is how I read from the inputstream if (responseCode == HttpURLConnection.HTTP_OK) InputStreamReader in= new InputStreamReader(uc.getInputStream()); BufferedReader br= new BufferedReader(in); while(br.ready()) { String next = br.readLine(); sb.append(next); } return sb.toString(); } although I dont read until I get the response code, is it possible that the first time I call br.ready() that I call it before it is ready, and therefore I don't read the input EDIT 2: Changing above code to simply String line; while ((line = br.readLine()) != null) { sb.append(line); } resolved the issue.

• Generic allocator class without variadic templates?

  - by rainer

  I am trying to write a generic allocator class that does not really release an object's memory when it is free()'d but holds it in a queue and returns a previously allocated object if a new one is requested. Now, what I can't wrap my head around is how to pass arguments to the object's constructor when using my allocator (at least without resorting to variadic templates, that is). The alloc() function i came up with looks like this: template <typename... T> inline T *alloc(const &T... args) { T *p; if (_free.empty()) { p = new T(args...); } else { p = _free.front(); _free.pop(); // to call the ctor of T, we need to first call its DTor p->~T(); p = new( p ) T(args...); } return p; } Still, I need the code to be compatible with today's C++ (and older versions of GCC that do not support variadic templates). Is there any other way to go about passing an arbitrary amount of arguments to the objects constructor?

• Exporting/Importing events to Outlook 2007 calendar - problem

  - by iandisme

  I work on a web app that involves scheduling. A user can view his schedule, and then download a meeting request file for a particular event. In Outlook 2003, simply opening this event would cause a meeting request to pop up and the user could accept, which would either add or update the event in their calendar. However, in Outlook 2007, the meeting request Accept function is disabled, and the reason given is that the user is the organizer and can't accept his own event request. The ICS file clearly shows that this is not the case. Has anyone experienced this same problem? Does anyone know how to work around it? (Using Outlook's import function is scarcely an option because it causes duplicate events to be created; the import function doesn't seem to care that the events have the same UID) Here is the ICS file: BEGIN:VCALENDAR PRODID:#{my app} VERSION:2.0 CALSCALE:GREGORIAN METHOD:REQUEST BEGIN:VEVENT DTSTAMP:20100324T150236Z UID:eeb639a1-f8e5-4eab-ab3c-232ad91364c6 SEQUENCE:2 ORGANIZER:#{myApp}.#{myDomain}.com DESCRIPTION: DTSTART;TZID=Europe/London:20110620T120010 DTEND;TZID=Europe/London:20110620T133010 SUMMARY:BREAK:Breakfast LOCATION:Room 101 END:VEVENT BEGIN:VTIMEZONE //Timezone info edited for brevity END:VTIMEZONE END:VCALENDAR

• OpenGL - drawing 2D polygons shapes with texture

  - by plonkplonk

  I am trying to make a few effects in a C+GL game. So far I draw all my sprites as a quad, and it works. However, I am trying to make a large ring appear at times, with a texture following that ring, as it takes less memory than a quad with the ring texture inside. The type of ring I want to make is not a round-shaped GL mesh ring (the "tube" type) but a "paper" 2D ring. That way I can modify the "width" of the ring, getting more of the effect than a simple quad+ring texture. So far all my attempts have been...kind of ridiculous, as I don't understand GL's coordinates too well (and I can't really understand the available documentation...I am just a designer with no coder help or background. A n00b, basically). glBegin(GL_POLYGON); for(i = 0;i < 360; i += 10){ glTexCoord2f(0, 0); glVertex2f(Cos(i)*(H-10),Sin(i)H); glTexCoord2f(0, HP); glVertex2f(Sin(i)(H-10),Cos(i)*(H-10)); glTexCoord2f(WP, HP); glVertex2f(Cos(i)H,Sin(i)(H-10)); glTexCoord2f(WP, 0); glVertex2f(Sin(i)*H,Cos(i)*H); } glEnd(); This is my last attempt, and it seems to generate a "sunburst" from the right edge of the circle instead of a ring. It's an amusing effect but definitely not what I want. Other results included the circle looking exactly the same as the quad textured (aka drawing a sprite literally) or something that looked like a pop-art filter, by working on this train of thought. Seems like my logic here is entirely flawed, so, what would be the easiest way to obtain such a ring? No need to reply in code, just some guidance for a non-math-skilled user...

• Play multiple audio files using AVAudioPlayer

  - by inScript09

  Hi all, I am planning on releasing 10 of my song recordings for free but bundled in an iphone app. They are not available on web or itunes or anywhere as of now. I am new to iphone sdk (latest) as you can imagine, so I have been going through the developer documentation, various forums and stackoverflow to learn. Apple's avTouch sample application was a great start. But I want my app to play all the 10 tracks one by one. All the songs are added to resources folder and are named as track1, track2...track10. In the avTouch app code I can see the following 2 parts which is where I think I need to make changes to achieve what I am looking for. But I am lost. // Load the array with the sample file NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"m4a"]]; - (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag { if (flag == NO) NSLog(@"Playback finished unsuccessfully"); [player setCurrentTime:0.]; [self updateViewForPlayerState]; } can anyone please help me on 1. how to load the array with all the 10 tracks which are added to resources folder 2. and when I hit play, player should start the first track. when the 1st track ends 2nd track should start and so on for the remaining tracks.

• Connecting to a network drive programmatically and caching credentials

  - by Chris Doggett

  I'm finally set up to be able to work from home via VPN (using Shrew as a client), and I only have one annoyance. We use some batch files to upload config files to a network drive. Works fine from work, and from my team lead's laptop, but both of those machines are on the domain. My home system is not, and won't be, so when I run the batch file, I get a ton of "invalid drive" errors because I'm not a domain user. The solution I've found so far is to make a batch file with the following: explorer \\MACHINE1 explorer \\MACHINE2 explorer \\MACHINE3 Then manually login to each machine using my domain credentials as they pop up. Unfortunately, there are around 10 machines I may need to use, and it's a pain to keep entering the password if I missed one that a batch file requires. I'm looking into using the answer to this question to make a little C# app that'll take the login info once and login programmatically. Will the authentication be shared automatically with Explorer, or is there anything special I need to do? If it does work, how long are the credentials cached? Is there an app that does something like this automatically? Unfortunately, domain authentication via the VPN isn't an option, according to our admin. EDIT: If there's a way to pass login info to Explorer via the command line, that would be even easier using Ruby and highline.

• Java Concurrency : Synchronized(this) => and this.wait() and this.notify()

  - by jens

  Hello Experts, I would appreciate your help in understand a "Concurrency Example" from: http://forums.sun.com/thread.jspa?threadID=735386 Qute Start: public synchronized void enqueue(T obj) { // do addition to internal list and then... this.notify(); } public synchronized T dequeue() { while (this.size()==0) { this.wait(); } return // something from the queue } Quote End: My Question is: Why is this code valid? = When I synchronize a method like "public synchronized" = then I synchronize on the "Instance of the Object == this". However in the example above: Calling "dequeue" I will get the "lock/monitor" on this Now I am in the dequeue method. As the list is zero, the calling thread will be "waited" From my understanding I have now a deadlock situation, as I will have no chance of ever enquing an object (from an nother thread), as the "dequeue" method is not yet finised and the dequeue "method" holds the lock on this: So I will never ever get the possibility to call "enequeue" as I will not get the "this" lock. Backround: I have exactly the same problem: I have some kind of connection pool (List of Connections) and need to block if all connections are checked. What is the correct way to synchronize the List to block, if size exceeds a limit or is zero? Thank you very much Jens

• How can I do batch image processing with ImageJ in Java or clojure?

  - by Robert McIntyre

  I want to use ImageJ to do some processing of several thousand images. Is there a way to take any general imageJ plugin and apply it to hundreds of images automatically? For example, say I want to take my thousand images and apply a polar transformation to each--- A polar transformation plugin for ImageJ can be found here: http://rsbweb.nih.gov/ij/plugins/polar-transformer.html Great! Let's use it. From: [http://albert.rierol.net/imagej_programming_tutorials.html#How%20to%20automate%20an%20ImageJ%20dialog] I find that I can apply a plugin using the following: (defn x-polar [imageP] (let [thread (Thread/currentThread) options ""] (.setName thread "Run$_polar-transform") (Macro/setOptions thread options) (IJ/runPlugIn imageP "Polar_Transformer" ""))) This is good because it suppresses the dialog which would otherwise pop up for every image. But running this always brings up a window containing the transformed image, when what I want is to simply return the transformed image. The stupidest way to do what I want is to just close the window that comes up and return the image which it was displaying. Does what I want but is absolutely retarded: (defn x-polar [imageP] (let [thread (Thread/currentThread) options ""] (.setName thread "Run$_polar-transform") (Macro/setOptions thread options) (IJ/runPlugIn imageP "Polar_Transformer" "") (let [return-image (IJ/getImage)] (.hide return-image) return-image))) I'm obviously missing something about how to use imageJ plugins in a programming context. Does anyone know the right way to do this? Thanks, --Robert McIntyre

• Best way to pass image to server?

  - by Chris

  I have an SL3 application that needs to be able to pass an image to the server, and then the server will generate a PDF file with the image in it, and display it to the user. What I already have in place are the following: (1) Code to convert image to byte array (2) Code to generate PDF file with image The main problem that I am running into is the following: In order to bypass the pop-up blocker, which is a requirement for my application, I am using the following code: var button = new NavigationButton(); button.NavigateUri = new Uri("http://localhost:3616/PrintReport.aspx?ReportIndex=11&ActionType=Get&ReportIdentifier=" + reportIdentifier.ToString() + ""); button.TargetName = "_blank"; button.PerformClick(); Initially, I would pass the image to a WCF web service (as a byte array), and then "navigate" to the ASP.NET page that would display the report. However, if I do this, then I can not use my custom HyperlinkButton class, and, certain browsers, including Safari, will block a new window from opening up. Therefore, it appears that the only option is to use the HyperlinkButton class. What I need to be able to do is to somehow pass the image, as a byte array or some other data type, to the server, such that it can temporarily store the image, even if it is in a server variable, and then immediately retrieve it when I navigate to the PrintReport.aspx page. If I upload the image to an ASP.NET form and then use the HyperlinkButton class to navigate to the PrintReport page, it doesn't work, as the app navigates to the PrintReport page before the system has finished uploading the image. I can't pass it to a web service, as that would require that I navigate to the PrintReport.aspx page in the callback code of the web method that I would be passing the image to, and the HyperlinkButton will not allow that, based on security rules. Any help or ideas would be appreciated. Thanks. Chris

• How can I control the action of onbeforeunload in IE?

  - by SpawnCxy

  Hi all I've got a problem about onbeforeunload recently that I need to pop up a voting page if the user try closes their IE browser.And I did it by using <body onbeforeunload="makevote()"> And the main structure of makevote() in javascript as follows: function makevote() { comet.distruct(); if(csid != null && isvote == null) { window.event.returnValue = false window.event.returnValue='press “cancel” to vote please!' showComDiv(popvote,"popiframe",400,120,'your vote here','dovote()'); } } For last three months this voting function performed so ugly that I got only less than 8,000 votes from more than 4,50,000 vistors.I think the problem is, when the users try to close their browsers,the onbeforeunload property pops up a comfirm box which covered my voting box while most users click the OK button,which means close comfirming is done,as a habit.So my question is how can I control the comfirming box made by onbeforeunload myself? So far I can only define the message it shows.For example if I click the "OK" ,I'll go to the voting box instead of closing my IE.And if there's any other better way to do this?Help would be greatly appreciated!

• Specify which xml file to load when link is clicked

  - by Jason

  Good morning, I would like it so when a link is clicked on the homepage it would load a particular xml file into the next page (the page is called category-list.apsx). This category list page uses the Repeater Control method to display the xml details on the page. I used the example shown here: http://www.w3schools.com/aspnet/aspnet_repeater.asp So at the moment the repeater script looks like: <script runat="server"> sub Page_Load if Not Page.IsPostBack then dim mycategories=New DataSet mycategories.ReadXml(MapPath("categories.xml")) categories.DataSource=mycategories categories.DataBind() end if end sub </script> After doing some research I did find someone with the same problem and the solution was to insert #tags as part of the link on the homepage (i.e. category-list.apsx#company1results) and then some script on the list page to pick up the correct xml file: <script type="text/javascript"> var old_onload = window.onload; // Play it safe by respecting onload handlers set by other scripts. window.onload=function() { var categories = document.location.href.substring(document.location.href.indexOf("#")+1); loadXMLDoc('XML/'+categories+'.xml'); old_onload(); } </script> This was from the following link: http://www.hotscripts.com/forums/javascript/45641-solved-specify-xml-file-load-when-click-link.html How can I get these two scripts to connect with each other? Thank you for your time

• DIY intellisense on XPath - design approach? (WinForms app)

  - by Cheeso

  I read the DIY Intellisense article on code project, which was referenced from the Mimic Intellisense? question here on SO. I wanna do something similar, DIY intellisense, but for XPath not C#. The design approach used there makes sense to me: maintain a tree of terms, and when the "completion character" is pressed, in the case of C#, a dot, pop up the list of possible completions in a textfield. Then allow the user to select a term from the textfield either through typing, arrow keys, or double-click. How would you apply this to XPath autocompletion? should there be an autocomplete key? In XPath there is no obvious separator key like "dot" in C#. should the popup be triggered explicitly in some other way, let's say ctrl-. ? or should the parser try to autocomplete continuously? If I do the autocomplete continuously, how to scale it properly? There are 93 xpath functions, not counting overloads. I certainly don't want to popup a list of 93 choices. How do I decide when I've narrowed it enough to offer a useful lsit of possible completions? How to populate the tree of possible completions? For C#, it's easy: walk the type space via reflection. At a first level, the "syntax tree" for C# seems like a single tree, and the list of completions at any point depends on the graph of nodes you've traversed to that point. Typing System.Console. traverses to a certain node in that tree, and the list of completions is the set of child nodes available at that node in the tree. On the other hand, the xpath syntax seems like it is a "flatter" tree - function names, axis names, literals. Does this make sense? what have I not considered?

• Chrome troubles...

  - by GaVrA

  Take this site for example: http://pms.rs/contact Everything is just fine just by using this css for textarea: #kontakt input, #kontakt textarea{ width:250px; } #kontakt textarea{ height:150px; } But ofc chrome is always smarter and in it user can drag that bottom right corner of textarea and resize it to the size he likes. Call me control freak, but that is very dumb thing to have if no other browser is using that. On sites like this it is not a big deal, but somewhere it can cover the entire content and for me personaly, i like to limit as much as possible what user can do so he does not break my site(like for example adding too large images in posts on forums...). So i have to do something like this: #kontakt input, #kontakt textarea{ width:250px; } #kontakt textarea{ height:150px; max-height:150px; max-width:250px; } Just so i get chrome to play as all other browsers do... While i was typing this i realised that i really dont have any question per se, but i just thought to share this with SO public, so i will mark this as community wiki. Also some other things i noticed are inputs, i always have to put width for input or textarea just because chrome is always not rendering them as he should.

• Custom Modal Window in WPF?

  - by Dan Bryant

  I have a WPF application where I'd like to create a custom pop-up that has modal behavior. I've been able to hack up a solution using an equivalent to 'DoEvents', but is there a better way to do this? Here is what I have currently: private void ShowModalHost(FrameworkElement element) { //Create new modal host var host = new ModalHost(element); //Lock out UI with blur WindowSurface.Effect = new BlurEffect(); ModalSurface.IsHitTestVisible = true; //Display control in modal surface ModalSurface.Children.Add(host); //Block until ModalHost is done while (ModalSurface.IsHitTestVisible) { DoEvents(); } } private void DoEvents() { var frame = new DispatcherFrame(); Dispatcher.BeginInvoke(DispatcherPriority.Background, new DispatcherOperationCallback(ExitFrame), frame); Dispatcher.PushFrame(frame); } private object ExitFrame(object f) { ((DispatcherFrame)f).Continue = false; return null; } public void CloseModal() { //Remove any controls from the modal surface and make UI available again ModalSurface.Children.Clear(); ModalSurface.IsHitTestVisible = false; WindowSurface.Effect = null; } Where my ModalHost is a user control designed to host another element with animation and other support.

• I'm having trouble with using std::stack to retrieve the values from a recursive function.

  - by Peter Stewart

  Thanks to the help I received in this post: http://stackoverflow.com/questions/2761918/how-do-i-use-this-in-a-member-function I have a nice, concise recursive function to traverse a tree in postfix order: void Node::postfix() { if (left != __nullptr) { left->postfix(); } if (right != __nullptr) { right->postfix(); } cout<<cargo<<"\n"; return; }; Now I need to evaluate the values and operators as they are returned. My problem is how to retrieve them. I tried the std::stack: #include <stack> stack <char*> s; void Node::postfix() { if (left != __nullptr) { left->postfix(); } if (right != __nullptr) { right->postfix(); } s.push(cargo); return; }; but when I tried to access it in main() while (!s.empty()) { cout<<s.top<<"\n"; s.pop; } I got the error: 'std::stack<_Ty::top': function call missing argument list; use '&std::stack<_Ty::top' to create a pointer to member' I'm stuck. Another question to follow shortly.
