• Uncheck all checkboxes in repeater except checkbox being checked

  - by Chris Laythorpe

  I know my question reads a bit like that 'how much wood can a woodchuck chuck' line, please excuse that... I have a repeater with checkboxes. There are numerous rows in this repeater - I never know how many - I want only one checkbox checked at any time. If the user changes the checked checkbox, any pre-existing checks are unchecked therefore maintaining a single checked checkbox. I am using VB, but comfortable to port any C#. I want to use JQuery. I have been looking on Google, but only ever seem to find ALL checked, ALL unchecked systems. Any suggestions?

• Using Unix Process Controll Methods in Ruby

  - by John F. Miller

  Ryan Tomayko touched off quite a fire storm with this post about using Unix process control commands. We should be doing more of this. A lot more of this. I'm talking about fork(2), execve(2), pipe(2), socketpair(2), select(2), kill(2), sigaction(2), and so on and so forth. These are our friends. They want so badly just to help us. I have a bit of code (a delayed_job clone for DataMapper that I think would fit right in with this, but I'm not clear on how to take advantage of the listed commands. Any Ideas on how to improve this code? def start say "*** Starting job worker #{@name}" t = Thread.new do loop do delay = Update.work_off(self) break if $exit sleep delay break if $exit end clear_locks end trap('TERM') { terminate_with t } trap('INT') { terminate_with t } trap('USR1') do say "Wakeup Signal Caught" t.run end end

  - by Steve

  Hi, I am trying to install oracle on snow leopard using these guidelines. http://blog.rayapps.com/2009/09/14/how-to-install-oracle-database-10g-on-mac-os-x-snow-leopard/ There is a step in the installation, where I have to change netca and dbca such that it runs in 32 bit mode. Can someone please tell me how to do it. I have pasted the exact step below –Now you need to modify $ORACLE_HOME/jdk/bin/java script and change “…java -Xbootclasspath…” to “…java -d32 -Xbootclasspath…”--

• WinForms: Why do I get InvalidCastException when showing folder browser dialog?

  - by Marek

  I am randomly getting InvalidCastException when showing FolderBrowserDialog and also many clients have reported this. I have not been able to find anything relevant on the internet. Does anyone know what causes this/how to fix this? My code: using (FolderBrowserDialog fbd = new FolderBrowserDialog()) { fbd.ShowNewFolderButton = false; if (fbd.ShowDialog() == DialogResult.OK) Stack trace: Error: System.InvalidCastException: 'Unable to cast object of type 'System.__ComObject' to type 'IMalloc'.'. Stack trace: at System.Windows.Forms.UnsafeNativeMethods.Shell32.SHGetMalloc(IMalloc[] ppMalloc) at System.Windows.Forms.FolderBrowserDialog.GetSHMalloc() at System.Windows.Forms.FolderBrowserDialog.RunDialog(IntPtr hWndOwner) at System.Windows.Forms.CommonDialog.ShowDialog(IWin32Window owner) at System.Windows.Forms.CommonDialog.ShowDialog() EDIT: Additional information: I have been able to reproduce this only when running in VS2008 debugger. When running out of debugger, it happens only very rarely (happened once or twice in 6 months) on my 64 bit Windows 7 and goes away after restart. The clients are certainly not running the app in debugger so it is surely reproducible out of debugger.

• How can I determine if jquery tab is shown because of user click or from tab rotation

  - by Richard Edwards

  I've been using the jQuery UI tabs for a bit now and an interesting request has come up. The current tab setup is using the rotation feature. I need to find a way to determine if the tab is shown because of the result of the rotation itself, or because a user physically clicked the tab. I've wired up all of the standard events, show and select and they fire regardless of the source of the tab change. Does anyone have any ideas? Basically I'd like to do something additional if the user clicked the tab, but not if the tab changes by itself via the rotation. If I wire up the click even to the tabs themselves it doesn't seem to get fired at all, I'm assuming because the tabs widget is using that event itself.

• Would an ORM have any way of determining that a SQLite column contains date-times or booleans?

  - by DanM

  I've been thinking about using SQLite for my next project, but I'm concerned that it seems to lack proper datetime and bit data types. If I use DbLinq (or some other ORM) to generate C# classes, will the data types of the properties be "dumbed down"? Will date-time data be placed in properties of type string or double? Will boolean data be placed in properties of type int? If yes, what are the implications? I'm envisioning a scenario where I need to write a whole second layer of classes with more specific data types and do a bunch of transformations and casts, but maybe it's not as bad as I fear. If you have any experience with this or a similar scenario, how did you handle it?

• how to debug SIGSEGV in jvm GCTaskThread

  - by ekeren

  Hi, My application is experiencing cashes in production. The crash dump indicates a SIGSEGV has occurred in GCTaskThread It uses JNI, so there might be some source for memory corruption, although I can't be sure. How can I debug this problem - I though of doing -XX:OnError... but i am not sure what will help me debug this. Also, can some of you give a concrete example on how JNI code can crash GC with SIGSEGV EDIT: OS:SUSE Linux Enterprise Server 10 (x86_64) vm_info: Java HotSpot(TM) 64-Bit Server VM (11.0-b15) for linux-amd64 JRE (1.6.0_10-b33), built on Sep 26 2008 01:10:29 by "java_re" with gcc 3.2.2 (SuSE Linux)

• Can I use Visual Studio 2010's compiler with Visual Studio 2008's Runtime Library?

  - by BillyONeal

  Hello everyone :) I have an application that needs to operate on Windows 2000. I'd also like to use Visual Studio 2010 (mainly because of the change in the definition of the auto keyword). However, I'm in a bit of a bind because I need the app to be able to operate on older OS's, namely: Windows 2000 Windows XP RTM Windows XP SP1 Visual Studio 2010's runtime library depends on the EncodePointer / DecodePointer API which was introduced in Windows XP SP2. If using the alternate runtime library is possible, will this break code that relies on C++0x features added in VS2010, like std::regex?

• shortest path search in a map represented as 2d shapes

  - by joe_shmoe

  Hi, I have a small library of a few shortest path search algorithms. They were developed for simple undirected graphs (the normal representation - vertices and edges). Now I'd like to somehow apply them on a bit different scenario - where the maps are represented as 2-dimensional shapes, connected by shared edges (edges of the polygons, that is). In this scenario, the search can start/end either at a map object or some point (x,y). What would be the best approach? Try to apply the algorithms onto shapes? or try to extract a 'normal' graph out of the shapes (I have preprocessing time available)? Any advice would be much appreciated, as I'm really not sure which way to go, and I don't have enough time (and skill) to explore many options... Thanks a lot

• Need help with foreach and XML

  - by danit

  I have the following output (via link) which displays the var_dump of some XML im generating: http://bit.ly/aoA3qY At the very bottom of the page you will see some output, generated by this code: foreach ($xml->feed as $entry) { $title = $entry->title; $title2 = $entry->entry->title; } echo $title; echo $title2; For some reason $title2 only outputs once, where there are multiple entries? Im using $xml = simplexml_load_string($data); to create the xml.

• taskbar-free window manager

  - by 7vies

  I'm looking for a window manager that is not based on the "standard" taskbar (which I find a poor idea and I'm completely tired of). I'm aware of tiling window managers and improvements in last versions of operating systems, but I can't find what I need. I suppose that any window takes the whole screen (or can be tiled), and I imagine switching between windows like that: on a hotkey or mouse hot zone the screen becomes a task switcher where tasks are organized in a somewhat convenient manner. Well, it's a bit like a taskbar with autohide, but I think there could be some more convenient ideas than simply stacking icons and descriptions... It is also supposed to be lightweight enough, for example to run on a netbook. Any suggestions?

• Ruby &&= edge case

  - by Alan O'Donnell

  Bit of an edge case, but any idea why &&= would behave this way? I'm using 1.9.2. obj = Object.new obj.instance_eval {@bar &&= @bar} # => nil, expected obj.instance_variables # => [], so obj has no @bar instance variable obj.instance_eval {@bar = @bar && @bar} # ostensibly the same as @bar &&= @bar obj.instance_variables # => [:@bar] # why would this version initialize @bar? For comparison, ||= initializes the instance variable to nil, as I'd expect: obj = Object.new obj.instance_eval {@foo ||= @foo} obj.instance_variables # => [:@foo], where @foo is set to nil Thanks!

• Where to put my xUnit tests for an F# assembly?

  - by Benjol

  I'm working on my first 'real' F# assembly, and trying to do things right. I've managed to get xUnit working too, but currently my test module is inside the same assembly. This bothers me a bit, because it means I'll be shipping an assembly where nearly half the code (and 80% of the API) is test methods. What is the 'right' way to do this? If I put the tests in another assembly, I think that means I have to expose internals that I'd rather keep private. I know that in C# there is a friend mechanism for tests (if that's the right terminology), is there an equivalent in F#? Alternatively, can anyone point me to an example project where this is being done 'properly'?

• How is conversion of float/double to int handled in printf?

  - by Sandip

  Consider this program int main() { float f = 11.22; double d = 44.55; int i,j; i = f; //cast float to int j = d; //cast double to int printf("i = %d, j = %d, f = %d, d = %d", i,j,f,d); //This prints the following: // i = 11, j = 44, f = -536870912, d = 1076261027 return 0; } Can someone explain why the casting from double/float to int works correctly in the first case, and does not work when done in printf? This program was compiled on gcc-4.1.2 on 32-bit linux machine.

• Which distribution website should I pick for my open-source package?

  - by Frank

  I wrote an open-source software package, which I'd like to publish (using Apache 2 license). I see various options for how/where to publish/host it: Get my own domain and put it there Put it on Sourceforge Put it on Google Code Put it on Freshmeat ...? What are your experiences / recommendations? What's the current trend among software developers? My only requirements are that I ... can add my own logo on the website can put up some documentation there, get a nice URL that is easy to remember get SVN support (I would also be fine with just uploading a tarball for each new version, it just shouldn't force me to use CVS or any other version control system I'm not familiar with) and of course, the site shouldn't take ownership in the code etc. oh, and it should be free (ok, for registering my own domain I'll be willing to pay a little bit)

• Changing property type in class that implements interface with object type property.

  - by used2could

  I know the title is a bit confusing but bare with me. (I'm up for suggestions on a new title lol) I'm writing a TemplateEngine that will allow me to use my own markup in text based files. I'm wanting to add controls as plugins as the application matures. Currently i've got a structure like the following: interface IControl string Id object Value class Label : IControl string Id string Value class Repeater : IControl string Id List<IControl> Value Now you'll see the strange part right away in the Repeater class with the Value property. I was hoping that having the Value type as object in the interface would allow me the flexibility to expand the controls as i go along. The compiler doesn't like this and for good reason i guess. Does anyone have any suggestions how to accomplish this? Note: Please don't go into suggesting things like use Spark View Engine for templating. There is a reason i'm creating extra work for myself.

• matlab: figure size, same axis size

  - by Art

  I have a figure with fixed size, like that: hFig = figure(1); set(hFig, 'Position', [200 200 500 500]) But the thing is, that I want to have my AXIS with fixed size (i want them to be a square), not (necessary) the whole figure... - see image attached, Y axis is a bit longer than X axis (of course longer in a meaning of display... X and Y axis range is set to the same value). How to adjust it? Thanks!

• Minimalistic PHP template engine with caching but not Smarty?

  - by Pekka

  There are loads of questions for "the right" PHP template engine, but none of them is focused on caching. Does anybody know a lightweight, high-quality, PHP 5 based template engine that does the following out of the box: Low-level templating functions (Replacements, loops, and filtering, maybe conditionals) Caching of the parsed results with the possibility to set an individual TTL per item, and of course to force a reload programmatically Extremely easy usage (like Smarty's) Modest in polluting the namespace (the ideal solution would be one class to interact with from the outside application) But not Smarty. I have nothing against, and often use, Smarty, but I am looking for something a bit simpler and leaner. I took a look at Fabien Potencier's Twig that looks very nice and compiles templates into PHP code, but it doesn't do any actual caching beyond that. I need and want a template engine, as I need to completely separate code and presentation in a way that a HTML designer can understand later on, so please no fundamental discussions about whether template engines in PHP make sense. Those discussions are important, but they already exist on SO.

• What javascript min tool does jquery use?

  - by JDS

  I have a great deal of javascript that needs to be min'd before being served to the end user. Currently, I'm using JSMIN, but I'd like to switch to something a bit more powerful (such as something with local variable replacement). I'm currently looking at YUI min developed by yahoo, and it got me thinking about the min tool that jquery uses. Does anyone know what it is and if it's publicly available? Also, any recommendations on other min tools that might be better suited than YUI min? If possible, I'd like a java solution so I can just plug the library into what I've already created for the JSMIN solution. Thanks

• Custom Providers & Design Patterns

  - by Code Sherpa

  Hi. I am using ASP.NET 2.0 and its various providers. I have overridden most of the methods I need and have the following custom providers: ProjectMembershipProvider ProjectProfileProvider ProjectRoleProvider In the design of my project, my intention was to wrap the custom providers in a facade - style design - mixing and matching profiling, membership, and roles in API methods to simplify things for developers. But, I am finding that a lot of the methods in my custom providers don't need to change, really. And, it seems silly to wrap a stand-alone method in another method that does exactly the same thing. So - is my approach wrong? Or, should I allow end - users to instantiate the custom providers when needed and the mix/match api when needed? This seems a bit redundant to me but I can't see another way. Advice appreciated. Thanks.

• How to register a function in a driver code as its ISR

  - by CVS-2600Hertz-wordpress-com

  Following the feedback i got from: http://stackoverflow.com/questions/2683682/new-to-linux-kernel-driver-development/2683819 I have written a driver (.c file) by comparing it with an existing driver and "borrowing" heavily from its code. The driver is registered fine and init() and probe() are working fine. I am also able to access the peripheral device registers. :-) However i am a bit hazy about the IRQ/ISR. The peripheral-device is a input device and raises an interrupt on a GPIO pin. How do i move ahead from my current state ( init(), probe(), etc. ) to be able to handle the IRQ and execute my ISR function?? Many-Thanks in Advance

• How to specify a font from javascript?

  - by Steven Lu

  I am trying to customize a view-src bookmarklet for iPad. This one is looking pretty good so far. But I want to make it just a little more readable: The Courier (New) font is a bit ugly even (especially?) on the retina display and I'd prefer any one of DejaVu Sans Mono, Monaco, Lucida Console, Bitstream Vera Sans Mono. I tried to modify the bookmarklet script by adding: pre.style.fontFamily = '"DejaVu Sans Mono", "Lucida Console", Monaco;'; It's not doing the trick. Perhaps prettyprint cancels out my fontFamily setting when it loads. Maybe I can set it at the end of the script somehow...

• iPhone: Best Method for Passing Data to and from a Server

  - by SAPNA

  I am developing an iPhone application that downloads data from a website. The website database is implemented in SQL and the site itself uses the classic ASP interface. I am unsure as to which method would be best for transferring data to and from the server. Both JSON and SOAP require XML processing and I'm not sure how that affects performance or which of those two is best. What would be the best method in general for data transfer given the server configuration we currently have? I very new to this field and I'm a bit confused. Any help would be appreciated.

• What does: throw 0 do/mean? Is it "bad"?

  - by MartinP

  Context I came across some code, like this: if( Some_Condition ) throw 0; I googled a bit, and found a few other code snippets using that odd looking throw 0 form. I presume one would catch this as: catch(const int& e) { } Or is this a NULL ptr? to be caught as void* ? Question What does this throw 0 do? Is it special in some way? My normal preference would be to throw something that is (or derived from) std::exception. So to me this looks "bad". Is it "bad" ?
