  • Drawing up a session value within SQL query? PHP and MySQL

    - by Derek
    Hi, on one of my web pages I want my manager user to view all activities assigned to them (personally). In order to do this, I need something like this: $sql = "SELECT * FROM activities WHERE manager = $_SESSION['SESS_FULLNAME']"; Now obviously this syntax is all wrong, but because I am new to this stuff, is there a way I can call up the full name from the user's session within a query? This is so that when I call up the database values to be displayed within the web page, only the activities for the manager who is logged in is displayed. For example, the activities table has a manager column of a full name entry. Any help is much appreciated. Thanks.

  • preventing selection on MKPointAnnotation

    - by Derek
    Is there a way to prevent an annotation in a MKMapView instance from being enabled. In other words, when the user taps the red pin on the map, is there a way to prevent it from highlighting the pin. Right now the pin turns dark when touched... Edit: I'm using the following code to return the MKPinAnnotationView // To future MKMapView users - Don't forget to set _mapView's delegate _mapView.delegate = self; _annotation = [[MKPointAnnotation alloc] init]; _annotation.coordinate = myLocation; [_mapView addAnnotation:_annotation]; -(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation{ MKPinAnnotationView *pin = [[MKPinAnnotationView alloc] initWithAnnotation:_annotation reuseIdentifier:@"id"]; pin.enabled = NO; return pin; }

  • g++ doesn't think I'm passing a reference

    - by Ben Jones
    When I call a method that takes a reference, g++ complains that I'm not passing a reference. I thought that the caller didn't have to do anything different for PBR. Here's the offending code: //method definition void addVertexInfo(VertexInfo &vi){vertexInstances.push_back(vi);} //method call: sharedVertices[index]->addVertexInfo(VertexInfo(n1index, n2index)); And here's the error: GLUtils/GLMesh.cpp: In member function 'void GLMesh::addPoly(GLIndexedPoly&)': GLUtils/GLMesh.cpp:110: error: no matching function for call to 'SharedVertexInfo::addVertexInfo(VertexInfo)' GLUtils/GLMesh.h:93: note: candidates are: void SharedVertexInfo::addVertexInfo(VertexInfo&)

  • Does Anyone Use This Site To Find Jobs? [closed]

    - by Derek
    I hope this isn't too far off-topic that it upsets people, but here goes: My company (me, in particular) are looking to hire entry-level and medium-experienced software engineers via non-traditional (career fairs, etc) avenues due to ineffective HR efforts in the past. So, I am looking to perhaps purchase resume searching from stackoverflow and/or job postings. Before I do, I was hoping a few people could chime in on whether they think this would be worthwhile. Do you post your resume on here? Do you actively search the job listings? Thanks!

  • Resize and center image in html/css?

    - by Derek
    Is there a way I can resize, crop, and center an image using html/css only? (img tag or css sprite) For example if I have a 500x500 pixel image, I want to resize that to a 250x250 pixel image I want to make the actual visible image to be 100x100, but still have the scale of a 250x250 sized image. I want the center of the image to be at a location x,y. Is that possible with only html/css, if not, how do you propose I go about it with javascript? Edit - ????: For (2), say my scaled image is now 200x200, and I want my visible image to be 100x100: So I guess what I mean is I want the scale and resolution of the image to be 200x200 but I want the visible image to be 100x100 or in other words the visible image would be at coordinates x,y: 0,0; 0,100; 100,0; 100,100; of the 200x200 image. Sorry, but I'm not good at explaining this.

  • Rails 3: Link_to :remote => true with JQuery?

    - by Derek
    Question update: I have figured out that importing JQuery (even without using it at all) is causing :remote => true to not work properly. I get the following error in the Chrome console: Uncaught TypeError: Object [object Object] has no method 'dispatchEvent' (prototype.js:5653) And when the link is clicked, it throws the same error again before redirecting. Responder.erb.html <ul> <% @choices.each_with_index do |choice, index| %> <li><%= link_to choice, { :action => "submit_response", :id => @id, :response => index }, :remote => true %></li> <% end %> </ul> Example generated HTML: <ul> <li><a href="/poller/submit_response/yni?response=0" data-remote="true">True</a></li> <li><a href="/poller/submit_response/yni?response=1" data-remote="true">False</a></li> </ul>

  • how to return NULL for double function with Intel C compiler?

    - by Derek
    I have some code that I am porting from an SGI system using the MIPS compiler. It has functions that are declared to have double return type. If the function can't find the right double, those functions return "NULL" The intel C compiler does not like this, but I was trying to see if there is a compiler option to enable this "feature" so that I can compile without changing code. I checked the man page, and can't seem to find it. Thanks

  • Applied style in WPF ignores properties.

    - by Quenton Jones
    Here's the conundrum. In two different places in my application, I use a border with the exact same appearance. In an never-ending fight against code bloat and unmanageable code, I want to define the border's appearance in a style to use when I create the border. Strangely, several of the properties I set are being ignored. Here's the code I use to create the style. Simple enough. Style borderStyle = new Style(typeof(Border)); borderStyle.Setters.Add(new Setter(Border.BorderBrushProperty, Brushes.Black)); borderStyle.Setters.Add(new Setter(Border.BorderThicknessProperty, new Thickness(4))); borderStyle.Setters.Add(new Setter(Border.OpacityProperty, 1.0)); return borderStyle; But when I set the style, the opacity property is left at its original value of 0.7. I have also tried setting the background of the border to a brush I created. It too is ignored. Thanks for any insights you may have.

  • How to discover getters and setters on hibernate objects

    - by Michael Jones
    I need to find a way of taking a hibernate object and discovering at runtime all of the getter methods that relate to persistable fields. I'm using annotations in the classes but have previously had difficulties working with them (I ran into a 2 year old bug the java developers still haven't fixed). Does anyone know how I can do this please, ideally without using annotations? Thanks. PS - What I'm trying to do here is to update a new object with values from an existing object dynamically.

  • accessing my public methods from within my namespace

    - by Derek Adair
    I am in the process of making my own namespace in JavaScript... (function(window){ (function(){ var myNamespace = { somePublicMethod: function(){ }, anotherPublicMethod: function(){ } } return (window.myNamespace = window.my = myNamespace) }()); })(window); I'm new to these kinds of advanced JavaScript techniques and i'm trying to figure out the best way to call public methods from within my namespace. It appears that within my public methods this is being set to myNamespace. Should I call public methods like... AnotherPublicMethod: function(){ this.somePublicMethod() } or... AnotherPublicMethod: function(){ my.somePublicMethod(); } is there any difference?

  • Set up CakePHP in a subdirectory; Wordpress is installed in the root

    - by Derek Chiang
    I have been searching for a solution for 2 hours but nothing seems to work... here is my problem: I have WordPress installed in the root (var/www). So by going to http://www.geekderek.com, I see my wordpress site. I put CakePHP in a subdirectory var/www/cakephp. I want to be able to see my CakePHP app by going to: www.geekderek.com/cakephp. However, currently this url just returns a Wordpress page saying "Content not found." I believe this problem can be solved by modifying .htaccess in my root directory. So here is my .htaccess: http://pastebin.com/sXJTRstB As you can see, I added this line to the default WP .htaccess file: RewriteRule ^cakephp(/(.*))?$ cakephp/app/webroot/$1 [QSA,L] However, for some reason this doesn't seem to work. Could anyone please tell me what is wrong?? Thank you so much!

  • Expected symbol problems with this function declaration

    - by Derek
    I am just getting back into the C programming realm and I am having an issue that I think is linker related. I am using cmake for the first time as well, so that could be adding to my frustration. I have included a third party header file that contains a typedef that my code is trying to use, and it has this line: typedef struct a a_t so my code has a_t *var; //later..... var->member;// this line throws the error which throws the error: dereferencing pointer to incomplete type So am I just missing another include file, or is this a linker issue? I am building this code in QtCreator and using cmake. I can dive on a_t to see that typedef declaration in the included header, but I can't seem to dive on "struct a" itself to see where it's coming from. Thanks

  • How to access a subset of XML data in Java when the XML data is too large to fit in memory?

    - by Michael Jones
    What I would really like is a streaming API that works sort of like StAX, and sort of like DOM/JDom. It would be streaming in the sense that it would be very lazy and not read things in until needed. It would also be streaming in the sense that it would read everything forwards (but not backwards). Here's what code that used such an API would look like. URL url = ... XMLStream xml = XXXFactory(url.inputStream()) ; // process each <book> element in this document. // the <book> element may have subnodes. // You get a DOM/JDOM like tree rooted at the next <book>. while (xml.hasContent()) { XMLElement book = xml.getNextElement("book"); processBook(book); } Does anything like this exist?

  • Can I push my working directory without first committing it?

    - by Derek
    I have my web server set up as a remote git repo, so I can type "git push staging" and my last commit goes live on the server. I used this tutorial to set this up. A lot of the time, I'm testing a new feature, and I want to test several iterations of it on the staging server, before it's ready to quality as a commit. Is there a way to push my working directory to the server without having to commit it first?

  • PHP delete script, return to 'viewsubjects.php?classroom_id=NO VALUE'

    - by Derek
    Hi, As the title states... I am deleting a 'subject' from a 'classroom' I view classrooms, then can click on a classroom to view the subject for that classroom. So the link where I am viewing subjects looks like: viewsubjects.php?classroom=23 When the user selects the delete button (in a row) to remove a subject from a class, I simply want the user to be redirected back to the list of subjects for the classroom (exactly where they were before!!) So I though this is simply a case of calling up the classroom ID within my delete script. Here is what I have: EDIT: corrected spelling mistake in code (this was not the problem) $subject_id = $_GET['subject_id']; $classroom_id = $_GET['classroom_id']; $sql = "DELETE FROM subjects WHERE subject_id=".$subject_id; $result = mysql_query($sql, $connection) or die("MySQL Error: ".mysql_error()); header("Location: viewsubjects.php?classroom_id=".$classroom_id); exit(); The subject is being removed from the DB, but when I am redirected back the URI is displaying with an empty classroom ID like: viewsubjects.php?classroom_id= Is there a way to carry the classroom ID through successfully through the delete script so it can be displayed after, allowing the user to be redirected back to the page? Thanks for any help!
