• How do I redirect output from the Visual Studio debugger?

  - by jeatsy

  In Visual Studio 2008, I can specify a message to be printed when a breakpoint is hit (by right-clicking the breakpoint and choosing 'When Hit...'). When the program is run, these messages appear in the Output Window. I would like to know, is there any way to redirect them to a file? Specifying file.txt as a command argument to the program does not work: this redirects the program's output, but not the debugger's. (FWIW the behaviour I wish to achieve is to get the debugger to repeatedly print a variable's value to a file, rather than peppering my code with printf/cout statements.)

• Web-based JSON editor that works like property explorer with AJAXy input form

  - by dreftymac

  Background: This is a request for something that may not exist yet, but I've been meaning to build one for a long time. First I will ask if anyone has seen anything like it yet. Suppose you have an arbitrary JSON structure like the following: { 'str_title':'My Employee List' ,'str_lastmod': '2009-June-15' ,'arr_list':[ {'firstname':'john','lastname':'doe','age':'33',} ,{'firstname':'jane','lastname':'doe','age':'34',} ,{'firstname':'samuel','lastname':'doe','age':'35',} ] } Question: Is there a web-based JSON editor that could take a structure like this, and automatically allow the user to modify this in a user-friendly GUI? Example: Imagine an auto-generated HTML form that displays 2 input-type-text controls for both title and lastmod, and a table of input-type-text controls with three columns and three rows for arr_list ... with the ability to delete or add additional rows by clicking on a [+][X] next to each row in the table. Big Idea: The "big idea" behind this is that the user would be able to specify any arbitrary (non-recursive) JSON structure and then also be able to edit the structure with a GUI-based interaction (this would be similar to the "XML Editor Grid View" in XML Spy).

• Telerik RadAjaxManager and Mouse Events in Chrome

  - by kuzco

  Whenever I'm using Telerik's RadAjaxManager in Chrome, the events sent to any mouse events I'm using are passed as null. For instance, the following: <img id="Image1" src="image.gif" onclick="alert(event)" /> <rad:RadAjaxManager ID="RadAjaxManager1" runat="server"> <AjaxSettings> </AjaxSettings> </rad:RadAjaxManager> Alerts null when clicking the image. This does not happen in IE or FF. The version of the RadAjaxManager is 1.8.5.0. I'm guessing the problem does not occur in later versions, but an upgrade is not an option at the moment. I tried Telerik's support forum, but they didn't really provide any answer. What could cause such a problem? And how can it be dealt with?

• Jawa Swing: Dialog with expanding / progressive disclosure?

  - by Electrons_Ahoy

  I've got a dialog in a desktop Java Swing app. What I want is a classic Windows-style Progressive Disclosure dialog, where pressing a "More Options" button opens up a whole extra batch of options on the dialog. (Which can then be hidden again by clicking that same button, which now says something like "Hide".) What's the right way to do this in Swing? I can't seem to google-up anything directly relating to this, and what I have found boils down to "reset the preferred dimensions to 0 and revalidate" which can't possibly be the right way to do this and also causes all kinds of wacky things to happen.

• How to handle multiple openIDs for the same user

  - by Sinan

  For my site I am using a login system much like the one on SO. A user can login with his Facebook, Google (Gmail openID), Twitter account. This question is not about specific oAuth or openID implementations. The question is how to know if the same user logins with different providers. Let me give an example: Bobo comes to site logins to site by clicking on "Login with Facebook". Because this is his first visit we create an account for him. Later Bobo comes to the site. This time he clicks on "Login with Google". So how do I know if this is the same person so I can add this provider to his account instead of creating a new (and duplicate) account. Can I trust solely on email? What is the best way to handle this. How does SO do it? Any ideas?

• ASP.NET Calendar control: HowTo stop resetting calendar when navigating Back in the browser

  - by user125873

  Hi All, I've implemented the ASP.NET Calendar control. I'm using it to show events happening in the area. THE PROBLEM Today is August 18th, so when the calendar loads, August is selected as the current month. If I navigate to say October, and then navigate to another page and then try to go back to the page with the Calendar by clicking the browser Back button, the Calendar resets back to August, instead of remaining at October. Can anyone recommend how I may circumvent this? Thanks!

• Transactional isolation level needed for safely incrementing ids

  - by Knut Arne Vedaa

  I'm writing a small piece of software that is to insert records into a database used by a commercial application. The unique primary keys (ids) in the relevant table(s) are sequential, but does not seem to be set to "auto increment". Thus, I assume, I will have to find the largest id, increment it and use that value for the record I'm inserting. In pseudo-code for brevity: id = select max(id) from some_table id++ insert into some_table values(id, othervalues...) Now, if another thread started the same transaction before the first one finished its insert, you would get two identical ids and a failure when trying to insert the last one. You could check for that failure and retry, but a simpler solution might be setting an isolation level on the transaction. For this, would I need SERIALIZABLE or a lower level? Additionally, is this, generally, a sound way of solving the problem? Are the any other ways of doing it?

• Redirects in RoR: Which one to use?

  - by scrr

  Hello, we are making a website that takes a generated incoming link and forwards the user who is clicking on it to another website while saving a record of the action in our DB. I guess it's basically what ad-services like AdSense do. However, what is the best way to redirect the user? I think html-meta-tag-redirects are out of question. So what other options are there? head :moved_permanently, :location => "http://www.domain.com/" This one is a 301-redirect. The next one is a 302: redirect_to "http://www.domain.com" Are there any others? And which is best to use for our case? The links are highly-dynamic and change all the time. We want to make sure we don't violate any existing standards and of course we don't want search-engines to tag us as spammers (which we are not, btw). Thanks!

• Should I be building GUI applications on Windows using Perl & Tk?

  - by CheeseConQueso

  I have a bunch of related Perl scripts that I would like to put together in one convenient place. So I was thinking of building a GUI and incorporating the scripts. I'm using Strawberry Perl on Windows XP and have just installed Tk from cpan about fifteen minutes ago. Before I go for it, I want some sound advice either for or against it. My other option is to translate the Perl scripts into VB and use Visual Studio 2008, but that might be too much hassle for an outcome that might end up all the same had I just stuck with Perl & Tk. I haven't looked yet, but maybe there is a module for Visual Studio that would allow me to invoke Perl scripts? The main requirements are: It must be able to communicate with MySQL It must be able to fetch & parse XML files from the internet It must be transportable, scalable, and sustainable What direction would you take?

• How to read custom file properties in c#

  - by Randy Gamage

  I'm looking for a way to read document properties in C#. I've heard about dsofile.dll, but it seems like an old COM wrapper, and was wondering if there is something more modern for the .NET framework/C#. What I'm actually reading is not an office document file, but a Solidworks .SLDDRW file, that has Custom properties. You can view and change these in Windows Explorer by right-clicking on the file, and going to the Properties window, Custom tab. Anyone know how to read these custom properties in C# / .NET 3.5? Thanks!

• Show them the default, and allow them to press escape or Ctrl-Z

  - by cf_PhillipSenn

  I have a table cell, and when the user clicks on it, I replace the contents of the table cell with an input tag with the current contents as the default. But I don't like it's behavior because there's a chance that the user can delete the contexts on the input simply by clicking on it a second time. $('.LastName').live('click', function() { var myText = $(this).text(); $(this).empty().append('<input name="LastName" id="LastName" value="' + myText + '" />'); document.myForm.LastName.focus(); }); Q: How do I give the user a default, plus allow them to press the escape key or Ctrl-Z while in the middle of an edit?

• What is the difference between a 32-bit and 64-bit processor?

  - by JJG

  I have been trying to read up on 32-bit and 64-bit processors (http://en.wikipedia.org/wiki/32-bit_processing). My understanding is that a 32-bit processor (like x86) has registers 32-bits wide. I'm not sure what that means. So it has special "memory spaces" that can store integer values up to 2^32? I don't want to sound stupid, but I have no idea about processors. I'm assuming 64-bits is, in general, better than 32-bits. Although my computer now (one year old, Win 7, Intel Atom) has a 32-bit processor.

• iPhone: How to Display Underlined Text in a Button?

  - by Warrior

  I want to display the mail ID in my view such that clicking the mail ID should open the mail composer view. I want to display the button text as underlined to show it is a hyperlink and for the button click event to call the mail composer view. At present, I am not able to show the button text underlined. I thought of placing a label above the button and adjusting the label property to get the underlined text but that did not work. Is there a different way to get the appearance and behavior I want?

• Is there a FSRef in iPhone SDK or is there something that can be FSRef's alternative?

  - by unknownthreat

  The question may sound stupid, but the thing is this: I am learning how to use a Audio Queue, and the example I've taken (aqtest) has been a nice guide for me until I recently found out that aqtest is not for iPhone. (stupid me) I served around the Internet and found out that there is no FSRef for iPhone. If possible, I want to find a way to work around FSRef thinggie. So here comes the question: can I use something else instead of FSRef that exists on the iPhone SDK? Or am I missing something?

• iPhone Accelerometer > csv > email

  - by Bradley Powers

  Hi all, I'm trying to collect data for a machine learning project I'm working on. What I'd like to do is collect accelerometer data from an iPhone, save it to a csv and email it to myself. My app currently is able to acquire data from the accelerometer, but I'm at a bit of a loss as to how to proceed. First of all, I'd like to acquire data for a preset amount of time (after playing a sound to the user) which I don't really know how to do, and I can't find good documentation for. Also, I'd like to save that to a csv, which there is some documentation on (specifically using the NSString writeToFile method). Any recommendations/ ideas? Thanks!

• Make jQuery-ui draggable handle cover entire page

  - by Acorn

  What would be the best way to make an element draggable when clicking anywhere in the window? Would I have to use a container <div> that covers the whole window? I tried making the body draggable but that didn't work. The problem with using a container <div> is that it moves and therefore doesn't cover the whole of the screen any more after it has been dragged. What about making a really vast container <div> that spans a large number of pixels in every direction so you would never get to the edge of it. Is that a bad idea? The idea (simplified) is to have a page with a square in the middle that can be dragged by dragging any part of the window. Here's a wonderfully unnecessary mockup :)

• UIActionSheet cancel button strange behaviour

  - by nevan

  I have a UIBarButtonItem opening an action sheet to offer users choices about what to do. Everything works as expected unless I try to click on the "Cancel" button. The target of the button appears to have moved up from where it should be. I can only activate it by clicking somewhere in the middle of the "Cancel" and "Ok" buttons. I've tried at action sheets in other applications and they work fine, so it's not just my big thumb. The action sheet is opening in a UIViewController - (void)showOpenOptions { UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:NSLocalizedString(@"Open link in external application?", @"Open in external application") delegate:self cancelButtonTitle:NSLocalizedString(@"Cancel", @"Cancel") destructiveButtonTitle:NSLocalizedString(@"Open Link", @"Open Link") otherButtonTitles:nil]; [sheet showInView:self.view]; [sheet release]; }

• Basic Login Script using php and mysql inquiry

  - by Matt

  Attempting to write a check for a login script to see if the username is available. Would the best way to write this query be to check if isset(!_POST[]) for both values (nick and pass) then connect to database WHERE the mysql database for the usernick requested return the user id if the usernick exists evaluate if isset($id) to see if the user name is taken and use that to continue to creating an entry Does this logically sound like a method to check for login without using excessive code sorry for not posting the code, it is on another computer and this computer is locked down by my administrator at work... Also, is there another way to evaluate if a value exists in the database? For instance, instead of setting $id to the return value of the mysql database can i just ping the mysql database for the information and have it return a Boolean result so I am not putting out any user information. Thanks, Matt

• What happened to the Windows "Midi Mapper"

  - by interstar

  I wrote a windows program many years ago, which created music by sending notes to the "midi mapper" (and thence to the midi-synth on my sound-card) Today, I have a soft-synth which, allegedly accepts midi information, so I'd assume it should be possible to use today's equivalent of a midi-mapper to route the midi output from my program to the soft-synth. There's clearly no longer a midi-mapper application in windows, but my program still works (on XP) in that it drives the built-in soundcard synth, so there must be some sort of midi handling layer in windows. How can I get at this? And maybe redirect the midi to the soft-synth?

• Best free site/blog to put video tutorial

  - by nash

  Hi, i am planning to upload a video tutorial on a particular software technology. The size of the videos will be around 600 MB's to say 1 GB. I am putting it for free for anyone to download. Is there any site/blog where i can put it.I am planning to divide the videos in parts and zip them. Does blogger or any other cms allow me to upload to there sites and put download links? Or is buying web space the only option? I am not keen on using youtube as i clearly want the user to download by clicking on links and not watch them online. Also i was thinking of just uploading the videos on rapidshare/megaupload/mediafire... and put just links on a blogger post. Any suggestion from you guys?

• SOAP - Why do I need to query for the values for an update?

  - by Phill Pafford

  I'm taking over a project and wanted to understand if this is common practice using SOAP. The process that is currently in place I have to query all the values before I do an update cause I need to pass back all the values that are not being updated. Does this sound right? Example Values: fname=phill lname=pafford address=123 main phone:222-555-1212 So if I just wanted to update the phone number I need to query for the record, get all the values and submit these values for an update. Example Update Values: fname=phill lname=pafford address=123 main phone:111-555-1212 I just want to know if this is common practice or should I change the functionality of this?

• Debugging JavaScript in Internet Explorer

  - by Erik W

  I am working on a relatively complex JavaScript-driven website. It runs great in all browsers except Internet Explorer. I am getting this very curious error: "A Runtime Error has occurred. Do you wish to Debug? Line: 93,865,600. Error: Expected ';'" The issue is, I don't have 93 million lines of code, and clicking "Yes" doesn't attach to Visual Studio like it normally does. I can click on 'No' and the website continues to run fine, but if a user doesn't have JavaScript debugging disabled, I don't want them to see this meaningless error. Suggestions/Tools/Plugins to get to the bottom of this? And yeah, I learned my lesson, switch over and check my project in Internet Explorer more often... Thanks,

• Bad event on java panel

  - by LucaB

  Hi I have a java panel with 4 buttons. When I click on of these buttons, a new frame appears and the first is hidden with setVisibile(false). On that new window, I have another button, but when i click it, I got the event corresponding to the fourth button of the first window. Clicking the button again does the trick, but of course this is not acceptable. Am I missing something? I just show the frames with nameOfTheFrame.setVisible(true); and I have MouseListeners on every button. The code of the last button is simply: System.exit(0); EDIT Sample code: private void btn_joinGamePressed(java.awt.event.MouseEvent evt) { GraphicsTools.getInstance().getCreateGame().setVisible(false); GraphicsTools.getInstance().getMainPanel().setVisible(false); GraphicsTools.getInstance().getRegistration().setVisible(true); } GraphicsTools is a Singleton.
