  • MFC: 'Gluing' two windows/dialogs together

    - by John
    I'm trying to set something up so my main dialog has one or more child dialogs, and these are glued/docked to the outside of the main dialog - when the main dialog is minimised, the children are too, when main dialog moves, children move with it. I'd tried setting child dialogs as having main dialog CWnd as parent, with CHILD style. But then they get clipped by the parent's boundary. If I set them as POPUP, they can be outside but then don't move with the parent. I'm looking at putting an OnMove handler on the parent dialog, but is there something built-in? And, should child dialogs still be children of the main dialog... I assume they should? This is VS2005 (I think VS2008 has some related functionality so I mention this).

  • how to use oracle package to get rid of Global Temp table

    - by john
    I have a sample query like below: INSERT INTO my_gtt_1 (fname, lname) (select fname, lname from users) In my effort to getting rid of temporary tables I created a package: create or replace package fname_lname AS Type fname_lname_rec_type is record ( fname varchar(10), lname varchar(10) ); fname_lname_rec fname_lname_rec_type Type fname_lname_tbl_type is table of fname_lname_rec_type; function fname_lname_func ( v_fnam in varchar2, v_lname in varchar2 )return fname_lname_tbl_type pipelined; being new to oracle...creating this package took a long time. but now I can not figure out how to get rid of the my_gtt_1 how can i say... INSERT INTO <newly created package> (select fnma, name from users)

  • Language restrictions on iPhone partially lifted?

    - by John Smith
    Apparently Apple has changed some term in the agreement again. From http://www.appleoutsider.com/2010/06/10/hello-lua/ section 3.3.2 is now Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application. instead of the original No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). I am more interested in embedding Lua, but other people have other embeddings they want to make. I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through. (BTW this is a terribly important question for me an my product.)

  • What's the advantage of an Adobe AIR app over a traditional desktop app?

    - by John
    I'm pretty familiar with using Adobe Flex & AS3, and compared with writing apps in JS/HTML I think it's very cool. However, since AIR is essentially a non-browser version of Flex with benefits like local storage, it seems to be competing as a cross-platform desktop application platform... and in that space it's much less mature than more established desktop technologies. So what's the advantage of creating a desktop application using AIR compared to something like Java (or C++ using a cross-platform GUI library like wxWidgets)? Java's equally capable of communicating with the server for instance, I'm not quite sure what AIR adds when competing head-to-head in the desktop development world?

  • Jquery conditionals, window locations, and viewdata. Oh my!

    - by John Stuart
    I have one last thing left on a project and its a doozy. Not only is this my first web application, but its the first app i used Jquery, CSS and MVC. I have no idea on how to proceed with this. What i am trying to do is: In my controller, a waste item is validated, and based on the results one of these things can happen. The validation is completed, nothing bad happens, which sets ViewData["FailedWasteId"] to -9999. Its a new waste item and the validation did not pass, which sets ViewData["FailedWasteId"] to 0. Its an existing waste item and the validation did not pass, which sets ViewData["FailedWasteId"] to the id of the waste item. This ViewData["FailedWasteId"] is set on page load using <%=Html.Hidden("wFailId", int.Parse(ViewData["WasteFailID"].ToString()))%> When the validations do not pass, then the page zooms (by window.location) to an invisible div, opens the invisible div etc. Hopefully my intentions are clear with this poor attempt at jquery. The new waste div is and the existing item divs are dynamically generated (this i know works) " So my question here is... Help? I cant even get the data to parse correctly, nor can i even get the conditionals to work. And since this happens after post, i cant get firebug to help my step through the debugger, as the script isnt loaded yet. $(document).ready(function () { var wasteId = parseInt($('#wFailId').text()); if (wasteId == -9999) { //No Issue } else if (wasteId < 0) { //Waste not saved to database } else if (wasteId == 0) { //New Waste window.location = '#0'; $('.editPanel').hide(); $('#GeneratedWasteGrid:first').before(newRow); $('.editPanel').appendTo('#edit-panel-row').slideDown('slow'); } else if (wasteId > 0) { //Waste saved to database } });

  • PHP PDO Username Availability Checker

    - by John Bernal
    I'm building a registration page that uses JQuery's validator plugin to validate the form. For the username, i used the remote method. So here's my jquery+html code: fiddle And here's Available.php: <?php $usr = $_POST["username"]; $link = new PDO('mysql:***;dbname=***;charset=UTF-8','***','***'); $usr_check = $link->prepare("SELECT * FROM Conference WHERE Username = :usr"); $link->bindParam(':usr', $usr); $usr_check->execute(); if($usr_check->rowCount()>0) echo "false"; else echo "true"; ?> So I have a test account in my database with the username: user. When I tried to submit my form with the same username, it didn't display the error saying "username taken" which means the php isn't correct. Any ideas where I went wrong? Thanks

  • Why does my git push hang after successfully pushing?

    - by John
    On a newly set up ssh git repo, whenever I push, I get normal output like this: ? git push Counting objects: 15, done. Delta compression using up to 4 threads. Compressing objects: 100% (9/9), done. Writing objects: 100% (9/9), 989 bytes, done. Total 9 (delta 7), reused 0 (delta 0) It happens very quickly, and the changes are immediately available on the server repo. But the output hangs there for about a minute, and then finishes with: To [email protected]:baz.git c8c391c..1de5e80 branch_name -> branch_name If I control-c before it finishes, everything seems to continue to be normal and healthy, locally and remotely. What is it doing while hanging? Is something configured incorrectly on the server side?

  • How can I make a new CTP (CakePHP) file in NetBeans?

    - by John Isaacks
    I have found a lot of info about adding CTP file support for NetBeans, but this is usually talking about code highlighting and treating a ctp file like a php file. This can be done at: Tools - Options - Miscellaneous - Files I have done this. However, when I try to create a NEW ctp file. I do not have the option. I tried going to Tools -> Templates to add a ctp template. There is no "new" button just an "add" button that looks for a file. I created a file on my desktop called cake_template.ctp on my desktop. I added it to the PHP templates in the template manager. I called the template "PHP Cake Template". Still when I go to create a new file, the option is not there. I restarted NetBeans, still the same. I just want to create a new .ctp file, it shouldn't be this difficult. Does anyone know how? I am using version 6.9.1

  • parsing position files in ruby

    - by john
    I have a sample position file like below. 789754654 COLORA SOMETHING1 19370119FYY076 2342423234SS323423 742784897 COLORB SOMETHING2 20060722FYY076 2342342342SDFSD3423 I am interested in positions 54-61 (4th column). I want to change the date to be a different format. So final outcome will be: 789754654 COLORA SOMETHING1 01191937FYY076 2342423234SS323423 742784897 COLORB SOMETHING2 07222006FYY076 2342342342SDFSD3423 The columns are seperated by spaces not tabs. And the final file should have exact number of spaces as the original file....only thing changing should be the date format. How can I do this? I wrote a script but it will lose the original spaces and positioning will be messed up. file.each_line do |line| dob = line.split(" ") puts dob[3] #got the date. change its format 5.times { puts "**" } end Can anyone suggest a better strategy so that positioning in the original file remains the same?

  • call_user_function_array() and __construct

    - by John
    I'm working on a simple framework, and I'm having a slight problem. I'd like to use call_user_function_array() to pass parameters to a function. That's fine, except the function I want to pass it to is __construct. I can't create an instance of an object with cufa(), and by instantiating an object, and then using cufa to call that instance's __construct(), I run into problems with a broken class because I'm calling the constructor twice (and one time it's called wrong.)

  • Overhead of calling tiny functions from a tight inner loop? [C++]

    - by John
    Say you see a loop like this one: for(int i=0; i<thing.getParent().getObjectModel().getElements(SOME_TYPE).count(); ++i) { thing.getData().insert( thing.GetData().Count(), thing.getParent().getObjectModel().getElements(SOME_TYPE)[i].getName() ); } if this was Java I'd probably not think twice. But in performance-critical sections of C++, it makes me want to tinker with it... however I don't know if the compiler is smart enough to make it futile. This is a made up example but all it's doing is inserting strings into a container. Please don't assume any of these are STL types, think in general terms about the following: Is having a messy condition in the for loop going to get evaluated each time, or only once? If those get methods are simply returning references to member variables on the objects, will they be inlined away? Would you expect custom [] operators to get optimized at all? In other words is it worth the time (in performance only, not readability) to convert it to something like: ElementContainer &source = thing.getParent().getObjectModel().getElements(SOME_TYPE); int num = source.count(); Store &destination = thing.getData(); for(int i=0;i<num;++i) { destination.insert(thing.GetData().Count(), source[i].getName(); } Remember, this is a tight loop, called millions of times a second. What I wonder is if all this will shave a couple of cycles per loop or something more substantial? Yes I know the quote about "premature optimisation". And I know that profiling is important. But this is a more general question about modern compilers, Visual Studio in particular.

  • How to test obtaining a list of files within a directory using RSpec?

    - by John Topley
    I'm pretty new to the world of RSpec. I'm writing a RubyGem that deals with a list of files within a specified directory and any sub-directories. Specifically, it will use Find.find and append the files to an Array for later output. I'd like to write a spec to test this behaviour but don't really know where to start in terms of faking a directory of files and stubbing Find.find etc. This is what little I have so far: it "should return a list of files within the specified directory" do end Any help much appreciated!

  • WebDav alternatives? Win server 2003, win 7.

    - by John
    I have an internal web page that I have an iframe with the source pointing to a webdav folder. This allows the user to drag and drop a number of files on the iframe window which a button on the main page then kicks off a server side task to process the files. I am looking for an alternative that will allow me to drag a group of files and drop them onto a target area of a web page which will then upload them to the web server. Ideally this would be in ASP.Net 2,3 or 4. Any suggestions? TIA J

  • Why does Ruby 1.9.2 remove "." from LOAD_PATH, and what's the alternative?

    - by John Feminella
    The latest changesets to Ruby 1.9.2 no longer make the current directory . part of your LOAD_PATH. I have a non-trivial number of Rakefiles that assume that . is part of the LOAD_PATH, so this broke them. Was there a particular justification for doing this? As for a fix, adding $: << "." everywhere works, but seems incredibly hacky and I don't want to do that. What's the preferred way to make my Rakefiles 1.9.2+ compatible?

  • Should we use Nexus or Artifactory for a Maven Repo?

    - by John Stauffer
    We are using Maven for a large build process ( 100 modules). We have been storing our external dependencies in source control, and using that to update a local repo. However, we are ready to graduate to a local repo that can cache central so that we don't have to proactively download all 3rd parties (but we can still have a local repo to pull from). In addition we want to publish our internal build artifacts from a nightly build so that developers don't have to build the world. We are considering Nexus and Artifactory. What are the reasons for preferring one over the other? Are there others we should be considering?

  • How to check if TypeIdenitifier(T) is an Object?

    - by John
    I'm creating a generic list class that has a member of type Array(Array of ). The problem is the class descruction,because the class is supposed to be used for types from byte to types inheriting TObject. Specifically: destructor Destroy; var elem:T; begin /*if(T is Tobject) then //Check if T inherits TObject {Compiler error!} for elem in FData do TObject(elem).Free;*/ // do not know how to do it SetLength(FItems,0); //FItems : Array of T inherited Destroy; end; How do I check if T is TObject so I can free every member if the typeidenitifier is a class,for example?

  • How to update (append to) an href in jquery?

    - by John Isaacks
    I have a list of links that all go to a google maps api. the links already have the daddr (destination) parameter in them as static. I am using Geo-Location to find the users position and I want to add the saddr (source address) to the links once I get the data. so basically I will need to add something like &saddr=50.1234567,-50.03452 at the tail end of all the links pointing to google maps All the links have a class called directions-link and from this page I have figured out how to change them: $("a.directions-link").attr("href", "http://www.google.com/"); However I only want to append my value to the end of the href without changing what the href already is. How can I do that? Thanks!!
