  • Detect click events outside div inside usercontrol

    - by toraan
    I have a div inside a user control that is displayed by the user after some event. I want to hide this div when user clicks anywhere elese on the page but not on the div (or not on any element that is inside the div). If it wasn't a user control I could use body's clieck event to check the target, but because this is usercontrol that is hosted by other page I can't just "play" with it's elements. How can I achieve that without using body of the hosting page?

  • Bad_alloc exception when using new for a struct c++

    - by bsg
    Hi, I am writing a query processor which allocates large amounts of memory and tries to find matching documents. Whenever I find a match, I create a structure to hold two variables describing the document and add it to a priority queue. Since there is no way of knowing how many times I will do this, I tried creating my structs dynamically using new. When I pop a struct off the priority queue, the queue (STL priority queue implementation) is supposed to call the object's destructor. My struct code has no destructor, so I assume a default destructor is called in that case. However, the very first time that I try to create a DOC struct, I get the following error: Unhandled exception at 0x7c812afb in QueryProcessor.exe: Microsoft C++ exception: std::bad_alloc at memory location 0x0012f5dc.. I don't understand what's happening - have I used up so much memory that the heap is full? It doesn't seem likely. And it's not as if I've even used that pointer before. So: first of all, what am I doing that's causing the error, and secondly, will the following code work more than once? Do I need to have a separate pointer for each struct created, or can I re-use the same temporary pointer and assume that the queue will keep a pointer to each struct? Here is my code: struct DOC{ int docid; double rank; public: DOC() { docid = 0; rank = 0.0; } DOC(int num, double ranking) { docid = num; rank = ranking; } bool operator>( const DOC & d ) const { return rank > d.rank; } bool operator<( const DOC & d ) const { return rank < d.rank; } }; //a lot of processing goes on here; when a matching document is found, I do this: rank = calculateRanking(table, num); //if the heap is not full, create a DOC struct with the docid and rank and add it to the heap if(q.size() < 20) { doc = new DOC(num, rank); q.push(*doc); doc = NULL; } //if the heap is full, but the new rank is greater than the //smallest element in the min heap, remove the current smallest element //and add the new one to the heap else if(rank > q.top().rank) { q.pop(); cout << "pushing doc on to queue" << endl; doc = new DOC(num, rank); q.push(*doc); } Thank you very much, bsg.

  • Generating custom-form documents from base-form plus XML?

    - by KlaymenDK
    Hi all, this is my first stack overflow, and it's a complex one. Sorry. My task is to generate custom documents from a basic template plus some XML without having a custom form design element for each case. Here's the whole picture: We are building a Lotus Notes (client, not web) application for world-wide application access control; the scope is something like 400.000 users being able to request access to any of 1000+ applications. Each application needs its own request form -- different number of approvers, various info required, that sort of thing. We simply can't have a thousand forms in a database (one per application), and anyway their maintenance really needs to be pushed from the developers to the application owners. So instead of custom forms, we'd like to create a generic "template" form that stores a block of basic fields, but then allows application owners to define another block of fields dynamically -- "I want a mandatory plain-text field named 'Name' here, and then a date field named 'Due' here that must be later than today's date, and then ...". I hope this makes sense (if not, think of it as a generic questionnaire application). I pretty much have the structure in place for designing the dynamic fields (form builder GUI - XML-encoded data - pre-rendered DXL for injecting into a form), including mark-up for field types, value options, and rudimentary field validation instructions. My problem is generating a document with this dynamic content injected at the proper location (without needing a custom form design element for each case). Doing the dynamic content via HTML is out. The Notes client web rendering is simply way too poor, and it would be quite a challenge to implement things like field validation instructions, date selectors, and name look-ups. DXL, on the other hand, would allow us to use native Notes fields and code. As a tech demo, I've managed to implement a custom form generator that injects the pre-rendered DXL for the dynamic content into a base form; but as I said, we don't want a ton of custom form design elements. I've tried to implement a way to create a document with the "store form in document" flag set, but once I've created the document from the base form, I can't get DXL access to the stored form design, and so I can't inject my dynamic content. I know this is not something Notes was ever intended to do. Has anyone ever tried something like it (and gotten away with it)? Thanks for reading this far. With a boatload of thanks in advance, Jan Gundtofte-Bruun

  • Is it possible to make a subclass of NSObject which support subnodes in IB for iPhone project?

    - by Eonil
    I'm making a custom UI element class for iPhone. It'll cool to edit my class on Interface Builder with hierarchy. Some of my class is management class like UINavigationController, but they're not one of them, subclasses from NSObject. Of course, I can place a NSObject instance on IB, but it cannot have a child node. Is there a way to enable adding child node to subclass of NSObject?

  • Soften a colour border, maybe with a gradient, programmatically.

    - by ProfK
    I have a narrow header in corporate colour, bright red, with the content below on a just-off-white background. Ive tried softening the long line where these colours meet using border type divs with intermediate backgrounds, but I think I need the original type curved gradient 'area transitions'. I could copy the 1024px wide, and too narrow (vertically), header gif from their web site, and chop it up for eight border images, but that seems clumsy, and I'm looking for something I can apply anywhere, without needing images. I am able to do round borders in the x-y plane, but I'm curious as to how I can apply a gradient to any chosen colour transition. The extra divs I'm using as border elements above and below '#top-section' arose when I was toying with making many divs for one bordered element. This seemed the ultimate in border manipulation, sans code, but very tedious to spec in CSS and lay out a new border for each bordered element. <div id="topsection"> <div style="float: right; width: 300px; padding-right: 5px;"> <div style="font-size: small; text-align: right;"> Provantage Media Management System</div> <div style="font-size: x-small; text-align: right;"> <asp:LoginStatus ID="loginStatus" runat="server" LoginText="Log in" LogoutText="Log out" /> </div> </div> <span style="padding-left: 15px;">Main Menu</span><span id="content-title"> <asp:ContentPlaceHolder ID="titlePlaceHolder" runat="server"> </asp:ContentPlaceHolder> </span> <div style="background-color: white; height: 2px;"> </div> <div style="background-color: white; height: 3px;"></div> And the CSS: #topsection { background-color: #EB2728; color: white; height: 35px; font-size: large; font-weight: bold; }

  • SVG Parser in Javascript

    - by jsight
    I believe that at one point, I saw a TinySVG implementation that worked in the browser, using the canvas element as the backend. I found a few sites that appeared to indicate it was at http://fuchsia-design.com/CanvaSVG/, however, that site appears to no longer exist. Is this project (or a similar one) still on the web anywhere?

    - by user332523
    Hello, I am having some problems getting some French text to convert to UTF8 so that it can be displayed properly, either in a console, text file or in a GUI element. The original string is HANDICAP+ES which is supposed to be HANDICAPÉES No matter how I tried converting it, it appears the same way. Any ideas on how I can do this conversion? Thanks, Cam

  • CSS Pseduo-selectors and IE

    - by Nimbuz
    I'd like to use css pseudo-selectors ( parent > child, element:first-child ) in my stylesheet but IE6 doesn't seem to recognize those. Is there any plugin (jQuery preferably) that would allow me to use pseudo-selectors freely without worrying about the damned IE6? Thanks

  • Temporary Onmouseover

    - by 2x2p1p
    Hi guys :) Css "over" selector applys a temporary style to an element, it isn't definitive: div:hover { background-color: red; } I can use the same thing with javascript but it is a bit complicate and impossible for several elements: var elem = document.getElementByTagName ("div")[0]; elem.onmouseover = function () { this.style.backgroundColor = "red"; } elem.onmouseout = function () { this.style.backgroundColor = "transparent"; } There is a better way ? Something like this: document.getElementByTagName ("div")[0].ontemporarymouseover = function () { // LoL this.style.backgroundColor = "red"; } Thanks

  • cons operator (::) in F#

    - by Max
    The :: operator in F# always prepends elements to the list. Is there an operator that appends to the list? I'm guessing that using @ operator [1; 2; 3] @ [4] would be less efficient, than appending one element.
