  • 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

  • User class - 'load' data

    - by John
    <?php class User { private $id; private $username; public function __construct($id = null) { $this->id = $id; if (!is_null($this->id)) { $this->load(); } } public function load() { } } ?> In the 'load' method I am going to load all the information from the current user (id) But I wonder how is the best way to load all info. I could grab all data and then just assign all private variables, but I assume there must be another "cheaper" way to get all the data so I can use as such $this-variable; And not have to ASSIGN every single data row, I select in the load method. How?

  • [C++] Is it possible to roll a significantly faster version of sqrt

    - by John
    In an app I'm profiling, I found that in some scenarios this functions are able to take over 10% of total execution time. I've seen discussion over the years of faster sqrt implementations using sneaky floating-point trickery, but I don't know if such things are outdated on modern CPUs. MSVC++ 2008 compiler is being used, for reference... though I'd assume sqrt is not going to add much overhead though.

  • Trying to understand crash log output

    - by John Smith
    I'm trying to understand debug output from a crash log. I have the following line from the crashlog: 22 FG 0x00022b94 0x1000 + 138132 I understand how to use atos on 0x00022b94 to get the source code location. What I would like to know is why the crash log helpfully splits that number into 0x1000 + 138132? I have googled and the googles failed me.

  • Assigning a pointer variable to a const int in C++?

    - by John
    I'm wondering if anyone can explain the following to me: If I write int i = 0; float* pf = i; I get a compile error (gcc 4.2.1): error: invalid conversion from ‘int’ to ‘float*’ Makes sense - they are obviously two completely different types. But if instead I write const int i = 0; float* pf = i; It compiles without error. Why should the 'const' make a difference on the right hand side of the assignment? Isn't part of the idea of the 'const' keyword to be able to enforce type constraints for constant values? Any explanation I have been able to come up with feels kind of bogus. And none of my explanations also explain the fact that const int i = 1; float* pf = i; fails to compile. Can anyone offer an explanation?

  • How do you extend the Site model in django?

    - by John Giotta
    What is the best approach to extending the Site model in django? Creating a new model and ForeignKey the Site or there another approach that allows me to subclass the Site model? I prefer subclassing, because relationally I'm more comfortable, but I'm concerned for the impact it will have with the built-in Admin.

  • Does Android 2.1's Browser Support HTML 5 and What Video Format Does It Play?

    - by John Giotta
    The company I work for produces allot of video and we want to target as many devices as possible, but the question came up of what does the Android do? I personally own an Android based phone running 2.1, but I can't seem to get the HTML 5 tag to work. Even when I can trigger the browser to playback the video it just throws a notification error that it can't. Are there guidelines to producing Android/HTML 5 compatible videos? Is it truly supported?

  • How to stop a MFC/win32 control re-painting

    - by John
    I have a CRichEditCtrl, and an algorithm works on its contents in-place, iterating through the contents and making changes. This seems to cause it to re-paaint every time, which causes flickering and a noticeable time to complete the operation, especially if the control starts scrolling. I wondered if there's a neat way for me to stop it repainting for a period. It's actually a custom subclass of CRichEditCtrl in use so I was thinking something like: void MyCustomEditCtrl::DoAlgorithm() { enableRepaint(false); ... //to the actual work ... enableRepaint(true); } What's the neatest approach? A custom on-paint handler which does nothing when an operation is in progress? Or can repainting actually be disabled?

  • Sometimes when visiting a php page, the browser asks me to download the .php file with nothing in it

    - by John
    I've noticed an unusual problem with some of my php programs. Sometimes when visiting a page like profile.edit.php, the browser throws a dialogue box asking to download profile.edit.php page. When I download it, there's nothing in the file. profile.edit.php is supposed to be a web form that edits user information. I've noticed this on some of my other php pages as well. I look in my apache error logs, but don't see any errors. How do i figure out why this is happening?

  • Maintaining many socket connections with a single thread

    - by John
    Many tutorials on socket communication I see seem to use 1 thread per socket. But on a server used for online gaming, you might have 10k concurrent users - 10k threads isn't probably a wonderful idea. I came across a tool (SmartFox) which claims to use a single thread for monitoring all socket connections, potentially thousands of them. This app happens to be in Java, but I figure C++ or C# could do the same... how would you achieve this?

  • Memcached in a trusted shared environment?

    - by John Kary
    We are a university IT organization that hosts all of the university's websites on several shared servers on our server room floor. We have several VMs, each running its own instance of Apache as a web server for each respective server. If we were going to setup a memcached server, is it feasible to use it as a shared instance? If shared by several servers, or even multiple web apps running on the same server, what's the best way to keep each app's cache stores separate? Prefix the key? Would each VM require its own instance of memcached, or could we setup 1 memcached server and allow our multiple VMs to read/write to it?

I've seen such for C#,there must be one for what I'd enjoy to read. If not, please list the new features available in Visual Studio 2010 for VC++.

  • Can I Have Polymorphic Containers With Value Semantics in C++11?

    - by John Dibling
    This is a sequel to a related post which asked the eternal question: Can I have polymorphic containers with value semantics in C++? The question was asked slightly incorrectly. It should have been more like: Can I have STL containers of a base type stored by-value in which the elements exhibit polymorphic behavior? If you are asking the question in terms of C++, the answer is "no." At some point, you will slice objects stored by-value. Now I ask the question again, but strictly in terms of C++11. With the changes to the language and the standard libraries, is it now possible to store polymorphic objects by value in an STL container? I'm well aware of the possibility of storing a smart pointer to the base class in the container -- this is not what I'm looking for, as I'm trying to construct objects on the stack without using new. Consider if you will (from the linked post) as basic C++ example: #include <iostream> using namespace std; class Parent { public: Parent() : parent_mem(1) {} virtual void write() { cout << "Parent: " << parent_mem << endl; } int parent_mem; }; class Child : public Parent { public: Child() : child_mem(2) { parent_mem = 2; } void write() { cout << "Child: " << parent_mem << ", " << child_mem << endl; } int child_mem; }; int main(int, char**) { // I can have a polymorphic container with pointer semantics vector<Parent*> pointerVec; pointerVec.push_back(new Parent()); pointerVec.push_back(new Child()); pointerVec[0]->write(); pointerVec[1]->write(); // Output: // // Parent: 1 // Child: 2, 2 // But I can't do it with value semantics vector<Parent> valueVec; valueVec.push_back(Parent()); valueVec.push_back(Child()); // gets turned into a Parent object :( valueVec[0].write(); valueVec[1].write(); // Output: // // Parent: 1 // Parent: 2 }

  • Should Wordpress be used to create a real estate listing site?

    - by John
    I have a real estate agent client who wants a website to list the properties he's selling. Although there are great 3rd party web apps out there that do this, he adamantly demands that I recreate a simple and custom website for him. I can do this quickly with a php framework like Code Igniter that comes with MVC, data access objects and data bind controllers. The database would be straightforward: t_page: generic content pages t_property: for each property on the market, has fields like address, price, #of bed rooms etc.. However, the client has heard many great things about Wordpress, and strongly advises that I build his real estate site with it. I've only used Wordpress to create blogs and relatively straightforward websites. SO I dont know how effective it is as a real estate property content management system or how effective it is for users to search for real estate properties based on attributes such as "# of bedrooms, square footage, is basement finished etc..." So my question is, is it a good idea to build a real estate agent website with Wordpress? Or should I try harder to convince him to build it with web framework like Code Igniter?

  • [Win32/MFC] Making group-boxes contain things

    - by John
    As I understand it, a group-box is just another control. Controls inside it are not owned by it, so unlike in Winforms, if you move a group-box the contained controls stay put. What would be the nicest way to address this? Just create your own data-structure mapping controls to 'container' group-boxes so that when the container is moved the children are automatically moved?
