• How to add a dynamically resolved activity name to the back stack (without using PARENT_ACTIVITY)?

  - by user3214249

  The goal is 1) Start activity A from AppWidgetProvider or any other background task (it is simple). 2) From activity A go to activity B after clicking Back button. The problem is that I can't set PARENT_ACTIVITY in AndroidManifest.xml, because the activity B class name gets determined at run time. So in one case I need to go to activity B, in other case it is another activity. Seems like I can't use TaskStackBuilder without PARENT_ACTIVITY. I could handle this in the finish() method of activity A, but it should be a simpler way to add activity B to the "back stack" when I run startActivity(intent). Any ideas?

• @Secured not working

  - by user3640507

  I am new to spring and trying to implement Role based authorization with the help of @Secured annotation. I have a method which is specifically for ADMIN and I have written @Secured ("ROLE_ADMIN") to secure it. @Secured ("ROLE_ADMIN") public void HelloUser(String name) { System.out.println("Hello ADMIN"); } Now when I call this method by creating a class object it gets called eventhough user dont have ADMIN authority But when I dont create an object and use @autowired annotation instead then it works i.e User is not allowed to access this method. In my security.xml as well as servlet.xml I have added <global-method-security secured-annotations="enabled" /> Can some one please tell me where I am going wrong or is this the natural behaviour in spring ?

• How to post on Facebook with Android using the latest SDK

  - by user645402

  All the samples I have seen so far seem to be using an earlier version of the SDK and the parameters and calls don't match. Using the latest SDK, I'm trying this: String access_token = facebook.getAccessToken(); Bundle bundle = new Bundle(); bundle.putString("access_token", access_token); bundle.putString("app_id", FACEBOOK_APP_ID); bundle.putString("message", "My First Post"); bundle.putString("description", "My First Description"); asyncrunner.request("me/feed", bundle, new RequestListener() { And i get back a call to onComplete() with response = "{"data":[]}. And nothing ever gets posted to my wall on FB. Perhaps I'm not waiting long enough? How long should I need to wait before it shows up?

• Sending OK Response over HTTP to a webpage request

  - by Prashant

  Hi, I am using an SMS Gateway to make my application receive SMSs. For this, the SMS Gateway sends a request to one of the pages in my application with the message as a querystring parameter. eg. http://myapplication/SMSReceiver.aspx?Message=PaulaIsHome. Now after my page gets invoked, I need to send an OK response to the SMS Gateway so that it doesn't keep retrying to send the same message to my application again and again. I cannot figure out how to send the OK response. I am using ASP .Net and C#. Thanks

• Forwarding activity result to parent, with singleTop launch mode

  - by Joe

  I have two activities: a MainListActivity, and a DetailViewActivity. DetailViewActivity is set with android:launchMode="singleTop". When clicking an item in the "main list" activity, it launches the "detail view" activity via: startActivityForResult(detailIntent, REQUEST_CODE_DETAIL); If I then call setResult(RESULT_OK, resultData); and finish(); from within the Detail activity, that resultData is received by the "main list" activity's onActivityResult(..) method correctly. However, if I implement a "see previous"/"see next" type of navigation within the Detail activity, and implement it using singleTop, that result no longer gets sent back to the initial activity: Intent nextItemIntent = this.createIntent(nextId); nextItemIntent.setFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT); startActivity(nextItemIntent); // at this point, my DetailActivity's onNewIntent() method is called, and the new data is loaded properly But from here, when I call setResult(..) and finish(), my MainList activity never receives the new/updated result. Anyone know what I'm doing wrong?

• Will I use HtmlDocument even I want to parse the HTML string using HtmlAglityPack ?

  - by skhan

  Hi everyone, I'm working in C#. I'm trying to extract the first instance of img tag from a HTML string (which is actually a post data). This is my code: private string GrabImage(string htmlContent) { String firstImage; HtmlAgilityPack.HtmlDocument htmlDoc = new HtmlAgilityPack.HtmlDocument(); htmlDoc.LoadHtml(htmlContent); HtmlAgilityPack.HtmlNode imageNode = htmlDoc.DocumentNode.SelectSingleNode("//img"); if (imageNode != null) { return firstImage = imageNode.ToString(); } else return firstImage=" "; } But it gets null in htmlDoc, will I use the HtmlDocument type even if I'm trying to parse the HTML from a string ? P.S btw is it the correct way of grabbing the first instance of image tag from my HTML string?

• 3d cube using canvas. Need a little improvement

  - by TimeManx

  I made this 3d cube using the following code Matrix mMatrix = canvas.getMatrix(); canvas.save(); camera.save(); camera.rotateY(-angle); camera.getMatrix(mMatrix); mMatrix.preTranslate(-width, 0); mMatrix.postTranslate(width, 0); canvas.concat(mMatrix); canvas.drawBitmap(bmp1, 0, 0, null); camera.restore(); canvas.restore(); camera.rotateY(90 - angle); camera.getMatrix(mMatrix); mMatrix.preTranslate(-width, 0); mMatrix.postTranslate(width2, 0); canvas.concat(mMatrix); canvas.drawBitmap(bmp2, width, 0, null); This is what it gives But what I need is It's because when Camera rotates the images, some part of the image gets hidden. Like this But I think this can be done.

• Visual Studio keeps inserting absurd default property value in designer file

  - by Bugz R us

  i have a simple usercontrol with following properties: public partial class RichTextEditorControl : UserControl { public string EditorText { get { return richTextBox1.Rtf; } set { richTextBox1.Rtf = value; } } public string EditorPlainText { get { return richTextBox1.Text; } set { richTextBox1.Text = value; } } } Now whenever I EDIT a form which contains this control, VS fills its designer file with the following code line, and then throws a designer error : this.richTextEditorControl1.EditorPlainText = global::Project.Resources.MyResources_de_DE.SomeString; Now I don't know where it gets this value from ??? I've searched entire solution, and nowhere there's mention of this var, except for 1 file, where it's needed ... Moreover, the code VS writes, has an error in it ?! It doesn't compile ... The only thing I can do is edit the designer file, but the next time I have to edit the form with the designer, the same error happens again ... Where on earth is VS getting this value from ??

• How do I save an altered image in matlab?

  - by ef-i-blinky

  So I am using the code located here: http://wwwx.cs.unc.edu/~sjguy/CompVis/Features/BlobDetect.m and I was wondering how to save the final blob detected image. The image that I am doing the blob detection on gets shown and then he manually draws the lines on the image here: Xbar = cx1+X.*cos(alpha)+Y.*sin(alpha); Ybar = cy1+Y.*cos(alpha)-X.*sin(alpha); line(Xbar', Ybar', 'Color', color, 'LineWidth', ln_wid); I then want to save this image using something like imwrite. I have been reading around and it seems that no one really has an answer to to this problem. Thanks for any help you can give me, Josh

• GUID not being generated automatically when db.submitchanges()

  - by BlindingDawn

  I have a couple of tables I ported over to a new database. Everything is exactly the same from the legacy one to the new one. The back-end code that submits the user generated data to the database is also the same. When I submit changes to the database, all of the submitted information populates the correct columns but the column that stores the GUID populates with all 0's. When I enter in the columns manually using SQL Server Management Studio, the GUID gets populated as it does in the legacy version. Am I missing something?

• Minimized window position in WPF

  - by DrLazer

  I am trying to save the position of a custom dialog to the users registry, so that when they reload the same dialog, it appears in the same place they moved or resized it to previously. I am saving the windows X position Y position Width and Height. It all works fine except for when the dialog is minimized. If the dialog is minimized and the user right clicks the dialogs representation on the taskbar (windows 7) they can click "close this window". Strangely, the number -32030 gets saved in the registry as the X and Y positions but the width and height get saved correctly. Any idea where this number comes from and what to do in this situation thx

• Why Flash can't be rendered in a Windows Service?

  - by Leonid

  I'm trying to solve a similar problem as was described here - to create a Windows Service for taking snapshots of rich webpages (html+js+flash) and saving them to a PDF file. The bundle Firefox+cmdlnprint did the trick for me. I wrote a simple program running as a service that invokes Firefox to make a PDF. All seems well, the PDF gets created, but Flash is completely missing. Although, when started not as a service, Flash renders just fine. Can anyone shed a light on what blocks Flash from rendering and if there's a workaround? thanks!

• Making JQuery horizontal accordion close on click

  - by user310404

  Example: http://vincent-massaro.com/map/ Currently, the script allows you to click on a piece of the accordion to open it, but it is set to close on mouseleave. When I set the mouseleave to .click, it gets confused and doesn't know what state it is in. The code controlling this is below, and the full script is in haccordion.js linked in the page source. If someone could help me modify this script, I would be very grateful! Thanks in advance. $target.click(function(){ haccordion.expandli(config.accordionid, this) config.$lastexpanded=$(this) }) if (config.collapsecurrent){ //if previous content should be contracted when expanding current $target.mouseleave(function(){ $(this).stop().animate({width:config.paneldimensions.peekw}, config.speed) }) }

• result set using two different views (from an if statement)

  - by mailman1979

  Hi All, I have a bit of code that works with a result set called "result" (original I know) but depending on the incoming variable I'd like to fire the specific query depending. I have the below in an if statement but that just makes the "result" recordset gets those nasty red lines and it doesn't work. I'm sure this is easy to work out. if (area == "dashboard") { IQueryable<ViewGetNavigationMainItem> result = (from m in _entities.ViewGetNavigationMainItems where m.area.Trim() == area.Trim() where m.state == "Online" where m.parentID == parentID orderby m.sequence ascending select m); } else { //Get the Content Items IQueryable<ViewGetNavigationContentItem> result = (from m in _entities.ViewGetNavigationContentItems where m.navID == navID where m.parentID == parentID orderby m.contentOrder ascending select m); } maxRecords = result.Count(); foreach (var item in result) { etc etc etc

• OOP question about functions that struck me all of a sudden.

  - by Nitesh Panchal

  Hello, May be my question is stupid. But i would like to get it cleared. We know that functions are loaded in memory only once and when you create new objects, only instance variables gets created, functions are never created. My question is, say suppose there is server and all clients access a method named createCustomer(). Say suppose all clients do something which fired createCustomer on server. So, if the method is in middle of execution and new client fires it. Will the new request be put on wait? or new request also will start executing the method? How does it all get managed when there is only one copy of function in memory? No book mentions answers to this type of questions. So i am posting here where i am bound to get answers :).

• Preloading images in HTML, is there a more modern way?

  - by John

  I have an image loaded by JS on a mouse event. It's a fairly big image so I want to make sure it gets pre-loaded. I reemmber some old techniques from years ago and found this example: <SCRIPT LANGUAGE = JAVASCRIPT> if (document.images) { img1 = new Image(); img2 = new Image(); img1.src = "imageName1.gif"; img2.src = "imageName2.gif" } </SCRIPT> I wondered if this is still good/relevant, or maybe browsers automatically detect unused images and preload them anyway? Note my page has to support IE6, so I might still need older techniques anyway, but I'm still interested if more modern browsers have a better way?

• What value should .net SqlCommand.ExecuteNonQuery() return if no rows are affected?

  - by peacedog

  I have the following code: int result = -1; StringBuilder sb = new StringBuilder(); SqlCommand cmd = MyConnection. sb.AppendLine("delete from Table1 where ID in"); sb.AppendLine("(select id from Table1 t1 where not exists(select * from Table2 t2 where t2.Table1ID = t1.ID))"); cmd.CommandText = sb.ToString(); result = cmd.ExecuteNonQuery(); _log.Info("StoredXMLDocument Records Deleted: " + result.ToString()); That SQL, in a more readable format, is: delete from Table1 where ID in (select id from Table1 t1 where not exists(select * from Table2 t2 where t2.Table1ID = t1.ID)) I know that the SQL, when executed directly in the database, deletes no rows. When this code runs, however, result gets a value of 1. I was expecting it to be 0. Am I missing something? Why is it 1?

• Wrong Editing Controls Displayed in UITableView

  - by CJC

  Hi all, I'm having a strange problem with UITableView. When the user taps the Edit button, the tableview (which is a grouped view with multiple sections) is supposed to show delete buttons for each row--except for the final row in each section, which has a green add button. When a user taps the green button, a new row is inserted, but now the final row gets a delete button. Even stranger, that delete button ACTS like an add button. So it seems there's a drawing glitch, rather than a problem in assigning the correct style. (Extensive NSLogging shows that the last cell is getting the Insert editing style correctly.) I've tried setting setNeedsDisplay on the cell and the tableView, I've tried reloading that section/row/the entire table, but the issue persists. Any ideas on how to get UITableView to explicitly redraw the editing controls?

If the class names in css files are different then it's not easy. Only thing that should change is images and background color etc. But the layout and css classes should remain same. Any help would be appreciated. Thanks in advance.

• Field contains foreign IDs for different tables

  - by Rich

  I am developing a php/mysql driven facebook game. I am stuck on an element the table design. When a user completes a task I want to trigger any number of events. I was thinking of something like so: tbl_events *event_id - serogate primary ID *task_id - foreign ID of the task just completed *event_type - what type of event e.g is it a facebook stream publish or a message to the user or does it unlock a new element of the game? *event_param - this is where it gets tricky... the event parameter is a problem for two reasons, 1) it will contain different foreign ids... dependent on the event_type and thus it will not be possible to join to x table. Meaning I would have to call two queries. 2) Most events require a single id or text, however some events require multiple parameters - like the facebook stream publish.

• Oauth2 External Browser Request - App Launches, Credentials received, Browser Not Updated

  - by Michael Drozdowski

  I'm using an external browser request to authenticate myself with the SoundCloudAPI in OSX. My app launches, and has a button that opens an external browser window to authenticate against SoundCloud. When I click "connect" in the new window, I get a "External Protocol Request" that is consistent with my custom launch URI scheme. Clicking this loads the app, and it gets the correct credentials. The trouble is, the browser window never changes - it simply says that it's connecting forever. There is no "connection confirmed" alert coming from SoundCloud. I know I'm logged in because I can make the correct calls to the API to get things such as my username. Why isn't the browser confirming the connection or dismissing? The same thing happens if I load the authentication in an internal WebView in the app.

• JavaScript apparently waits for each AJAX call before sending another in a loop

  - by itako

  Hello. Straight to the point: I have this javascript: for(item=1;item<5;item++) { xmlhttp=new XMLHttpRequest(); xmlhttp.open("GET",'zzz.php', true); xmlhttp.send(); } And in PHP file something like this: usleep(5);die('ok'); Now the problem is javascript seems to be waiting for each ajax call to be completed before sending another one. So the first response gets back after approx. 5 seconds, next after 10 seconds and so on. That's a very simplified version of what I do, since the real script involves using cURL in PHP and jQuery as JS lib. But the problem remains the same. Why do responses come back in 5 second intervals?
