• C# form - checkboxes do not respond to plus/minus keys - easy workaround?

  - by Scott

  On forms created with pre dotNET VB and C++ (MFC), a checkbox control responded to the plus/minus key without custom programming. When focus was on the checbox control, pressing PLUS would check the box, no matter what the previous state (checked/unchecked), while pressing MINUS would uncheck it, no matter the previous state. C# winform checkboxes do not seem to exhibit this behavior. Said behavior was very, very handy for automation, whereby the automating program would set focus to a checkbox control and issue a PLUS or MINUS to check or uncheck it. Without this capability, that cannot be done, as the automation program (at least the one I am using) is unable to query the current state of the checkbox (so it can decide whether to issue a SPACE key to toggle the state to the desired one). I've gone over the properties of a checkbox in the Visual Studio 2008 IDE and could not find anything that would restore/enable response to PLUS/MINUS. Since I am in control of the sourcecode for the WinForms in question, I could replace all checkbox controls with a custom checkbox control, but blech, I'd like to avoid that - heck, I don't think I could even consider that given the amount of refactoring that would need to be done. So the bottom line is: does anyone know of a way to get this behavior back more easily than a coding change?

• Show a number with specified number of significant digits

  - by dreeves

  I use the following function to convert a number to a string for display purposes (don't use scientific notation, don't use a trailing dot, round as specified): (* Show Number. Convert to string w/ no trailing dot. Round to the nearest r. *) Unprotect[Round]; Round[x_,0] := x; Protect[Round]; shn[x_, r_:0] := StringReplace[ ToString@NumberForm[Round[N@x,r], ExponentFunction->(Null&)], re@"\\.$"->""] (Note that re is an alias for RegularExpression.) That's been serving me well for years. But sometimes I don't want to specify the number of digits to round to, rather I want to specify a number of significant figures. For example, 123.456 should display as 123.5 but 0.00123456 should display as 0.001235. To get really fancy, I might want to specify significant digits both before and after the decimal point. For example, I might want .789 to display as 0.8 but 789.0 to display as 789 rather than 800. Do you have a handy utility function for this sort of thing, or suggestions for generalizing my function above? Related: Suppressing a trailing "." in numerical output from Mathematica

• Sharing Eclipse directory on Dropbox between Windows and Mac OS X

  - by sowbug

  This question was close to mine, but not quite. I have a Windows desktop and a MacBook Pro. I'd like to be able to keep my Eclipse workspace in my Dropbox folder. The problem is that many project settings change between platforms: references to JREs, JDKs, and other libs. Every discussion I've seen of this problem seems to suggest taking advantage of the source control system's ignore functionality, so that such-and-such file remains local-only and thus able to remain platform-specific. But when you're working with a real single shared folder, that class of solution doesn't apply. Have you had luck working with a Java Eclipse project living in a single folder shared over the network, cross-platform?

• Google Document export via API

  - by micco

  After using Zend_GData to retrieve a document list feed, I can use the content URLs in the form: http://docs.google.com/document/edit?id=<docid>&hl=en but the source URLs in the form http://docs.google.com/feeds/download/documents/Export?docId=<docid>&exportFormat=html are returning 404 errors. That URL should return the content of the document in the requested format but it is returning 404. This problem is mentioned without resolution on a Google API forum. As indicated in that forum post, this problem only seems to affect new documents. My code works perfectly retrieving old documents, but new ones are 404. Has something changed in the way Google references new documents or in the way permissions are assigned? The code I'm using is essentially the same as the code on this page but this does not seem to be an issue specific to PHP/Zend_Gdata.

• Perl, get all hash values

  - by Mike

  Let's say in Perl I have a list of hash references, and each is required to contain a certain field, let's say foo. I want to create a list that contains all the mappings of foo. If there is a hash that does not contain foo the process should fail. @hash_list = ( {foo=>1}, {foo=>2} ); my @list = (); foreach my $item (@hash_list) { push(@list,$item->{foo}); } #list should be (1,2); Is there a more concise way of doing this in Perl?

• Best way to support large dropdowns

  - by JustAProgrammer

  Say I have a report that can be restricted by specifying some value in a dropdown. This dropdown list references a table with 30,000 records. I don't think this would be feasible to populate a dropdown with! So, what is the best way to provide the user the ability to select a value given this situation? These values do not really have categories and even if I subdivided (by having some nesting dropdown situation) by the first letter of the value, that may still leave a few thousand entries. What's the best way to deal with this?

• Has anyone seen this h:commandLink behavior?

  - by Liggy

  I have a very simple JSF form: <h:form id="simpleSearch"> <h:inputText id="surname" value="#{myBean.surname}" required="true" /> <h:commandLink>Search</h:commandLink> </h:form> When this page is rendered, the anchor that is generated looks like this (for brevity, I stripped out the generated onclick code): Search<a href="#" onclick="..."></a> As you can see, the "Search" is outside the anchor and the anchor body is empty. This is useless to me. I can't use this. Are there any suggestions/references/miracles out there to help me fix/understand what is going on here? Thanks!

• How Android retrieves info of the Stacked Activities which are killed when memory goes low.

  - by taranfx

  I was reading on how Activities communicate and how the calls stack up on top of each other. But at any instant when the OS(or dalvik) is low on resources, it can choose to kill Paused or Stopped Activities. In this scenario, how do we restore previous state of the activity(in which it was before getting killed) when we reach the same activity on our way back. Does stack store the state as well as references to the Activity? Aren't their chances of achieving a different state when we re-constuct activity (onCreate)?

• Forcing an app to run single core only?

  - by Kevin

  I have this strange issue with some third party DLL's. The third party provider references some open source DLL's that have a memory exception whenever I try to use a certain method. This issue does not appear when the app is run on a single core machine, but obviously we cannot assume a user will have that. Is there a way to force an app, or even better yet a referenced DLL to run on a single core? Any other way to possibly fix this? Getting the third party to rebuild the OS dll's is apparently out of the question (its a bit of a sore spot with me currently :) ) so I have to handle it myself or just forget about providing this functionality.

• Is there command-line tool to extract typedef, structure, enumeration, variable, function from a C or C++ file?

  - by FooF

  I am desiring a command-line tool to extract a definition or declaration (typedef, structure, enumeration, variable, or function) from a C or C++ source file. Also a way to replace an existing definition/declaration would be handy (after transforming the extracted definition by a user-submitted script). Is there such generic tool available, or is some resonably close approximation of such a tool? Scriptability and ability to hook-up with user created scripts or programs is of importance here, although I am academically curious of GUI programs too. Open source solutions for Unix/Linux camp are preferred (although I am curious of Windows and OS X tools too). Primary language interests are C and C++ but more generic solution would be even better (I think we do not need super accurate parsing capabilities for finding, extracting and replacing a definition in a program source file). Sample Use Cases (extra - for the curious mind): Given deeply nested structs and variable (array) initializations of these types, suppose there is a need to change a struct definition by adding or reordering fields or rewriting the variable/array definitions in more readable format without introducing errors resulting from manual labor. This would work by extracting the old initializations, then using a script/program to write the new initializations to replace the old ones. For implementing a code browsing tool - extract a definition. Decorative code generation (e.g. logging function entries / returns). Scripted code structuring (e.g. extract this and that thing and put in different place without change - version control commit comment could document the command to perform this operation to make it evident and verifiable that nothing changed). Note about tags: More accurate tag than code-generation would be code-transformation but it does not exist.

• how do I get the SDK version for an app running on the simulator programmatically?

  - by newbiez

  I am trying to get the version/build that is running on the simulator via code. Basically I am checking various features of my app using the simulator, and want to switch code paths on and off based on which SDK do I have set as current, instead than doing it by hand every time (my testing machine has different version of the SDK on it and I switch the current for testing purposes between 4.1 and 5.1). So the idea is that when the app launch on the simulator, I can read the build of the SDK and know trough matching (I have a function that does the matching and turn on and off the features) if I should run a specific code path or not. I know how to figure out if I am running on the sim or on a device, but cannot find references about how to get the version of the SDK via code, so I am basically stuck. Is there any function that I can call and that returns me the build or version of the currently installed iOS, while I am running the app on the simulator?

• How can I get the domain name for a user logged into a Mac via Active Directory

  - by Lawrence Johnston

  In my Cocoa app how can I get the current user's domain when they're logged in via Active Directory? I need to determine two things: 1. If the current user is logged on to an Active Directory domain (only need to handle Active Directory). 2. If 1, the domain of the user. I've found references to Directory Services and the Open Directory Programming Guide but the latter is 10.6 only (I must support 10.5+) and I could not find any examples for the former that gave me an idea of what I needed to do.

• How to add a web service reference in a DLL

  - by dan

  I'm creating a DLL with a reference to web services (I don't have the choice to do so) but I have to add web service references to the project that uses the DLL for it to work. Example, I have the DLL called API.DLL that calls a web service called WebService.svc that I want to use in a project called WinForm. First, I have to add a "Service Reference" to WebService.svc in API.DLL. Then, I add a reference API.DLL to WinForm but it doesn't work unless I also add a service reference to WebService.svc in WinForm. What can I do to avoid that last step?

• where clausule on field defined by sub-query

  - by stUrb

  I have this query which displays some properties and count the number of references to it from an other table: SELECT p.id,p.propName ( SELECT COUNT(*) FROM propLoc WHERE propLoc.propID = p.id ) AS number FROM property as p WHERE p.category != 'natural' This generates a good table with all the information I want to filter: id | propName | number 3 | Name 1 | 3 4 | Name 2 | 1 5 | Name 3 | 0 6 | Name 4 | 10 etc etc I now want to filter out the properties with number <= 0 So I tried to add an AND number > 0 But it reacts with Unknown column 'number' in 'where clause' apparently you can't filter on a name specified by a subquery? How can I achieve my goal?

• Can’t dup NilClass - how to trace to offender

  - by fullware

  This exception occurs often and intermittently when in development mode, and appears to get triggered by model associations. Does There are lots of references found by google but none seem to help to trace the problem to an offending class. Does anyone have any insight into how to trace the occurrence of this exception to it's cause? I've seen the posts on adding "unloadable" but I'm not sure I buy it--unless there's a way to trace it somehow to its cause. I'm not in favor of indiscriminately adding such things to every class in hopes the problem might go away. Rails 2.3.5.

• Does invoking System.gc() in java suggest garbage collection of the tenured generation as well as th

  - by Markus Jevring

  When invoking System.gc() in java (via JMX), it will dutifully (attempt to) clean the young generation. This generally works very well. I have never seen it attempt to clean the tenured generation, though. This leads me to two questions: Can the tenured generation even be collected (i.e. is there actually garbage in this generation, or do all objects in the tenured generation actually still have live references to them)? If the tenured generation can be collected, can this be done via System.gc(), or is there another way to do it (unlikely), or will I simply have to wait until I run out of space in the tenured generation?

• Why does Visual Studio 2008 try to open a project from the wrong folder?

  - by Rising Star

  I'm having a bizarre problem with Visual Studio 2008. I wanted to debug one of the libraries that my web application references. Therefore, I decide to add the project containing the library to my solution so that I can debug them together. The project containing my library sits at c:\webLibs\myproj.vbproj. However, when I try to add the project to my solution, Visual Studio throws the following error: "The project file 'c:\someOtherFolder\myproj.vbproj'. has been moved, renamed, or is not on your computer." As you can see, VS appears to be trying to open a different file than the one I clicked on. I used to have the file in that other location, but not anymore. I've tried restarting VS several times. What could cause this bizarre behavior? Why would Visual Studio try to open my project from the wrong folder?

• Using libraries with different licenses (CPOL + LGPL)

  - by jaens

  I'm developing a program that will be published on my university's website. In this program I use two libraries, one under the LGPL and one under the CPOL (link text). I plan on releasing the complete source code, libraries included (without modification). Do those licenses clash? What do I have to do to "fix" it? Do I have to do anything in particular (put text in source code files, put references in documentation...)? Thanks in advance.

• How does * work in Python

  - by Deqing

  Just switched from C++ to Python, and found that sometimes it is a little hard to understand ideas behind Python. I guess, a variable is a reference to the real object. For example, a=(1,2,5) meaning a - (1,2,5), so if b=a, then b and a are 2 references pointing to the same (1,2,5). It is a little like pointers in C/C++. If I have: def foo(a,b,c): print a,b,c a=(1,3,5) foo(*a) What does * mean here? Looks like it expands tuple a to a[0], a[1] and a[2]. But why print(*a) is not working while print(a[0],a[1],a[2]) works fine?

• What do we call this?

  I'm wondering what do we call this kind of assignment. <?php class SimpleClass { public $var1; public $var2; public $var3; public function SimpleClass() { $this->var1 = 'one'; $this->var2 = 'two'; $this->var3 = 'three'; } } function test() { $objSc = new SimpleClass(); $objSc->var4 = 'WTF?!'; # <-- what do we call this? var_dump($objSc); } test(); ?> Better with references or links. Thanks in advance!

• What exactly is GRASP's Controller about?

  - by devoured elysium

  What is the idea behind Grasp's Controller pattern? My current interpretation is that sometimes you want to achieve something that needs to use a couple of classes but none of those classes could or has access to the information needed to do it, so you create a new class that does the job, having references to all the needed classes(this is, could be the information expert). Is this a correct view of what Grasp's Controller is about? Generally when googling or SO'ing controller, I just get results about MVC's (and whatnot) which are topics that I don't understand about, so I'd like answers that don't assume I know ASP.NET's MVC or something :( Thanks

• open window with dynamic content

  - by julio

  Is it possible to open a window from PHP that has predefined content? It's obvious how you can open a window from a javascript link that frames an existing page, or just do a target=_blank from a regular a tag that references an existing page. But I am generating a bit of content, and want that content to be opened in a new link (or streamed to the viewer)-- something like (clearly psuedo code!): $content = "Hello World. <br />Nice to meet you!"; <a href="#" target="_blank" content=$content>Open up!</a> Is this possible? Thanks!

• How to get the innerHTML of a XML document (AJAX)?

  - by JCOC611

  After an AJAX query, a XML file is returned. I'm able to "parse" that file, but when it comes to getting the "innerHTML" (or in this case "innerXML" lol) of an element, I fail. If the XML element, let's say "content", only contained text I could do: content.childNodes[0].nodeValue (assuming that content references the XML element "content"). But that element contains other elements: <stackoverflow reason="tribute to this page"> <content> <div><span><p>Some more HTML elements</p></span></div> </content> </stackoverflow> I need to copy the content of <content> to an existing <div> in the page, how could I do that? Ex. myDiv.innerHTML = content.innerHTML;

• Any way to stringify a variable id / symbol in Python?

  - by otz

  I'm wondering if it is possible at all in python to stringify variable id/symbol -- that is, a function that behaves as follows: >>> symbol = 'whatever' >>> symbol_name(symbol) 'symbol' Now, it is easy to do it on a function or a class (if it is a direct reference to the object): >>> def fn(): pass >>> fn.func_name 'fn' But I'm looking for a general method that works on all cases, even for indirect object references. I've thought of somehow using id(var), but no luck yet. Is there any way to do it?

• Basic Objective-C syntax: "%@"?

  - by cksubs

  Hi, I'm working through the Stanford iPhone podcasts and have some basic questions. The first: why is there no easy string concatenation? (or am I just missing it?) I needed help with the NSLog below, and have no idea what it's currently doing (the %@ part). Do you just substitute those in wherever you need concatenation, and then comma separate the values at the end? NSString *path = @"~"; NSString *absolutePath = [path stringByExpandingTildeInPath]; NSLog(@"My home folder is at '%@'", absolutePath); whereas with any other programing language I'd have done it like this: NSLog(@"My home folder is at " + absolutePath); Thanks! (Additionally, any good guides/references for someone familiar with Java/C#/etc style syntax transitioning to Objective-C?)
