• Where's the font setting for folders in the Package Explorer?

  - by Carl Smotricz

  I'm talking about Eclipse (3.5 = Galileo), running under Kubuntu 9.10 and I have the Subversive plugin. I've been moved from Gnome-Ubuntu to Kubuntu, and one side effect was that some fonts are now just too tiny to read. File names in the explorer have a decent size, but folders are shown in a too-small font, and after having adjusted all the fonts in General|Appearance|Colors and Fonts the folders are unchanged. Maybe I'm just blind. I'd appreciate it if someone could point me to where I can adjust the font for folders in the Package Explorer

• How do i plot a vertical axis with variable intervals (Flex Charts or any other)

  - by satish

  How do i plot a vertical axis with variable intervals? on a Flex Chart. I want to plot a data set that has values from 0.1 to 800. When I use a standard Numerical Axis, I have to define a interval. I tried using Log-Axis, but I am not sure how to plot the point values. Looks like something in lines of semi-log axis would be better. A axis with initial values in Numerical, but later shifting gears to a Log-Axis. Any ideas or pointers to implement this in Flex?

• Need help in translating code from C to Java.

  - by Vuntic

  From this article. Here's the code: float InvSqrt(float x){ // line 0 float xhalf = 0.5f * x; int i = *(int*)&x; // store floating-point bits in integer i = 0x5f3759d5 - (i >> 1); // initial guess for Newton's method x = *(float*)&i; // convert new bits into float x = x*(1.5f - xhalf*x*x); // One round of Newton's method return x; } ...I can't even tell if that's C or C++. [okay apparently it's C, thanks] Could someone translate it to Java for me, please? It's (only, I hope) lines 2 and 4 that are confusing me.

• Flash in VC++ Documentation

  - by Red Serpent

  Hi I am trying to host a flash object inside an CAxWindow, I have managed to insert a shockwaveflash (SWF) and its working fine. I am trying to find all available API's that are available in the flash ocx. I am unable to find any documentation for the functions in the IShockwaveFlash interface. I know that Adobe doesn't have a documentation for using flash in VC++ but I was wondering if anyone can point me to a place where I can find an UNOFFICIAL documentation for flash.ocx or code samples as the only API that I could find and I'm currently using is "PutMovie". Any help is appreciated...

• Is it advisable to have non-ascii characters in the URL?

  - by Ravi Gummadi

  We are currently working on a I18N project. I was just wondering what are the complications of having the non-ascii characters in the URL. If its not, what are the alternatives to deal with this problem? EDIT (in response to Maxym's answer): The site is going to be local to specific country and I need not worry about the world wide public accessing this site. I understand that from usability point of view, It is really annoying. What are the other technical problem associated with this?

• Why does Spring Security Core RC4 require Grails 2.3?

  - by bksaville

  On the Spring Security Core plugin GitHub repo, I see that Graeme on May 21st upped the required version of Grails from 2.0 to 2.3 before the RC4 version was released a couple of months later, but I don't see any explanation for why. Was it mismatched dependencies, bug reports, etc? I run a 2.2.4 app, and I would prefer not to upgrade at this point just to get the latest RC of spring security core. I understand if the upgrade to 3.2.0.RELEASE of spring security caused mismatched dependencies with older versions of Grails since I've run into the same issues before. This originally came up due to a pull request on the spring security OAuth2 provider plugin that I maintain. The pull request upped the required version to 2.3, and the requester pointed me to the RC4 release of core as the reason. Thanks for the good works as always!

• Android: Constructing a triangle based on Geographical information

  - by Aidan

  Hi Guys, I'm constructing a geolocation based application and I'm trying to figure out a way to make my application realise when a user is facing the direction of the given location (a particular long / lat co-ord). I've got the math figured, I just have the triangle to construct. Here's a further clarification of what I want to do.. I just want to know is there a way to get java to construct 2 other co-ordinates based on my orientation in relation to true north and my current co-ordinate? I'd like to construct a tri-angle, 45 degrees out each way of my current location (one of the points) and 1 kilometer in that direction. The problem is I don't know how to make Android/Java recognise that I want to find that point in the direction I'm currently facing.. Anyone got any ideas?

• Use google analytics custom events for feedback form.

  - by chacko

  I was thinking of having a simple feedback form in my website. It would be something like: Your Feedback will help us improve. [ ] and then a textfield/textarea where the user can type (let's say) up to 100 characters of feedback. Rather than handling it all myself on the serverside I was thinking to use google analytics (since my site is already wireup) and everytime a user writes a comment send a custom event to google analytics. I think it might work. Can people suggest a better approach or point out any problem with this idea thanks

• DB2 Child Table - Auto Delete With Parent

  - by gamerzfuse

  I have a bit of a task before me. (DB2 Database) I need to create a table that will be a child table (is that what it is called in SQL?) I need it so that it has a foreign key constraint with my other table, so when the parent table is modified (record deleted) the child table also loses that record. Once I have the table, I also need to populate it with the data from the other table (if there is an easy way to UPDATE this). If you could point me in the right direction, this would help alot, as I do not even know what syntax to look for. Thanks in advance

• Handling Messages in Console Apps/DLLs in C++ Win32

  - by vsimon

  I would like to have the ability to process Win32 messages in a console app and/or inside a standalone DLL. I have been able to do it in .NET with the following article and it works great in C# inside a console app and standalone DLL http://msdn.microsoft.com/en-us/magazine/cc163417.aspx Is there a way to do the equivalent with C/C++ Win32 APIs? I have tried doing RegisterClassEx(...) and CreateWindow(...) even passing in HWND_MESSAGE to hWndParent but the trouble is that after the "invisible" window is created messages are not being processed probably due to the lack of a message pump. Where would the message pump go if you had a DLL entry point? I have tried creating another thread in a DLL and put while(GetMesage(..)) there but that did not work either. Any ideas?

• Hit Testing with CALayer using the alpha properties of the CALayer contents.

  - by Charliehorse

  I'm writing a game for Mac using Cocoa. I'm currently implementing hit testing and have founds that CALayer offers hit testing, but does not seem to implement the alpha properties. As I have at times many CALayers stacked on top of each other, I really need to find a way to determine what the user actually meant to click on. I'm thinking if I could somehow get an array that contains pointers to all of the CALayers that contain the click point, I could filter through them some how. However the only way I've got so far to create the array is: NSMutableArray* anArrayOfLayers = [NSMutableArray array]; for (CALayer* aLayer in mapLayer.sublayers) { if ([aLayer containsPoint:mouseCoord]) [anArrayOfLayers addObject:aLayer]; } Then sort the array by the CALayer's z-values then go through checking if the pixel at location is alpha or not. However, between the sort and the alpha check this seems to be an incredible performance hog. (How would you even check the alpha?) Is there any way to do this?

• Silverlight/WPF: Retreiving the size of a `UIElement` once it has been rendered on screen

  - by ondesertverge

  I have the following simple piece of code: var canvas = new Canvas(); foreach (var ztring in strings) { var textblock = new TextBlock(); textblock.Text = ztring; panel.Children.Add(textblock); textblock.Measure(infiniteSize); } At this point I would expect any of the size properties (Height/Width, ActualHeight/ActualWidth, DesiredSize, RenderSize) to give me the size of the textblock. None of them do. ActualHeight always gives 16.0 no matter what size font. ActualWidth changes according to the text length but not the font size. I change the font size on the parent container and not the TextBlock itself. I feel like I am missing some basic element of understanding the manipulation of silverlight elements from within the codebehind. The question is: how do I get the real actual pixel size of my TextBlock?

• How to use git feature branches with live updates and merge back to master?

  - by karlthorwald

  I have a production website where master is checked out and a development webiste where I develop in feature branches. When a feature is merged into master I do this on the development site: (currently on the new-feature branch) $ git commit -m"new feature finished" $ git push $ git checkout master $ git merge new-feature $ git push And on the production site: (currently on master branch) $git pull This works for me. But sometimes the client calls and needs a small change on the website quickly. I can do this on production on master and push master and this works fine. But when I use a feature branch for the small change I get a gap: (On production on branch master) $ git branch quick-feature $ git checkout quick-feature $ git push origin quick-feature $ edit files... $ git add . $ git commit -m"quick changes" $ git push # until this point the changes are live $ git checkout master #now the changes are not live anymore GAP $ git merge quick-feature # now the changes are live again $ git push I hope I could make clear the intention of this workflow. Can you recommend something better?

• Appropriate high level language to deal with binary data

  - by fortran

  Hi, I need to write a small tool that parses a textual input and generates some binary encoded data. I would prefer to stay away from C and the like, in favour of a higher level, (optionally) safer, more expressive and faster to develop language. My language of choice for this kind of tasks usually is Python, but for this case dealing with binary raw data can be problematic if one isn't very careful with the numbers being promoted to bignums, sign extensions and such. Ideally I would like to have records with named bitfields that are portable to be serialised in a consistent manner. (I know that there's a strong point in doing it in a language I already master, although it isn't optimal, but I think this could be a good opportunity to learn something new). Thanks.

• Language construct naming: Function/Goto

  - by sub

  How is a language construct with the following properties called? It has a beginning and an end, just like a function It has a header containing it's name, also like a function but without arguments There can be any number of statements between its beginning and end, like a function You can use a function to jump to its beginning from anywhere (even itself) and it will execute the statements contained in it until it reaches its end You can use a function to immediately stop the execution of its contents and jump back where it was called from The code it contains is in the same scope as everything else, so you can access all variables outside and create new ones which aren't deleted upon leaving the construct. All in all it is like a goto point with an end and the option to return where it was called from.

• javascript singleton question

  - by Shawn

  I just read a few threads on the discussion of singleton design in javascript. I'm 100% new to the Design Pattern stuff but as I see since a Singleton by definition won't have the need to be instantiated, conceptually if it's not to be instantiated, in my opinion it doesn't have to be treated like conventional objects which are created from a blueprint(classes). So my wonder is why not just think of a singleton just as something statically available that is wrapped in some sort of scope and that should be all. From the threads I saw, most of them make a singleton though traditional javascript new function(){} followed by making a pseudo constructor. Well I just think an object literal is enough enough: var singleton = { dothis: function(){}, dothat: function(){} } right? Or anybody got better insights? [update] : Again my point is why don't people just use a simpler way to make singletons in javascript as I showed in the second snippet, if there's an absolute reason please tell me. I'm usually afraid of this kind of situation that I simplify things to much :D

• Problem with do construct in haskell

• Stopping function on event in vb.net

  - by afilatun

  I have a vb.net application which does some processing. This processing can take a while. The application doesn't respond until the processing has ended and then it handle all events (such as click on buttons) that the user has done during the processing. I'd like to add a "Stop" button so that the user can stop the processing at some point. How can I do that? Could threading the processing (which is done in a function of the application) be a possible solution? I tried to add a button which change a boolean value and putting the code of the processing function inside a while statement based on that boolean value. However it doesn't work because the click event on the button is processed only after the end of the processing.

Any ideas why this could be happening. Thanks.

• Fast exchange of data between unmanaged code and managed code

  - by vizcaynot

  Hello: Without using p/invoke, from a C++/CLI I have succeeded in integrating various methods of a DLL library from a third party built in C. One of these methods retrieves information from a database and stores it in different structures. The C++/CLI program I wrote reads those structures and stores them in a List<, which is then returned to the corresponding reading and use of an application programmed completely in C#. I understand that the double handling of data (first, filling in several structures and then, filling all of these structures into a list<) may generate an unnecessary overload, at which point I wish C++/CLI had the keyword "yield". Depending on the above scenario, do you have recommendations to avoid or reduce this overload? Thanks.
