  • php, get an end date based on start date and number of months

    - by mike
    Hi! I need to calculate an end date based on todays date and a number of months. For example, todays date 04/01/2010 and the number of months is 6. Are there any functions I can use to do some math that would return "10/01/2010"? Also, I think it's important to note that I am storing the result in MySQL as a "DATETIME" so I guess I would have to do something with the time as well... ??? Thanks!

  • Design Solution For Storing-Fetching Images

    - by Chaitanya
    This is a design doubt am facing, I have a collection of 1500 images which are to be displayed on an asp.net page, the images to be displayed differ from one page to another, the count of these images will increase in the time to come, a.) is it a good idea to have the images on the database, but the round trip time to fetch the images from the database might be high. b.) is it good to have all the images on a directory, and have a virtual file system over it, and the application will access the images from the directory Do we have in particular any design strategy in a traditional database for fetching images with the least round trip time, does any solution other than usage of a traditional database exists? ps: I use SQL Server to store these images.

  • Is there an open source cross-platform push server?

    - by Ian
    I'm currently in need of a (preferably open-source) free push server, that supports both linux and windows. I need something similar to the Ajax Push Engine, but that project unfortunatelly does not work on windows (I could use a virtual machine, but that's not what I'm looking for). I need to be able to push information to/from a python daemon, from a php script, to/from javascript and to a Blackberry application (built with java). Is there any tool that could help me with that? I've also looked into the Orbited project but frankly it lacks a lot of documentation and it's been very complicated to understand it. I'm not sure if it could work for me since it isn't actually a push server, but rather a proxy for it's built in MorbidQ server (or am I wrong?). Would a technology like Advanced Message Queing Protocol work for a project like this? Something like RabbitMQ or ActiveMQ? Thank you very much for the help.

  • Recursive compilation using gcc

    - by curiousexplorer
    I am using the gcc compiler. My project source tree looks like somewhat like this test$~: tree . . |-- folder | |-- hello.cpp | `-- hello.h `-- main.cpp 1 directory, 3 files test$~: The file main.cpp contains the main() function and all the functions invoked by main.cpp lie in the directory named folder So far in all my little projects I never had to put some source code under a sub-directory. What I am looking for, in short, is some gcc command for recursive compilation in sub-directories and their subdirectories and so on... This command should be invoked from the home directory of the code project.

  • IO.Directory.Exists always returns true

    - by roygbiv
    I am executing a IO.Directory.Exists on a network share from an ASP.NET application running under a specific Application Pool with a specific user account. The call always returns true. I have tried several variations: \\server\share$\directory \\192.168.0.1\share$\directory H:\directory I have checked that directory and share permissions are available to the account. The path does have spaces in it \\server\share$\directory\name name\test test, which should make no difference, however I have read otherwise. I will continue to check permissions, as it does work from my local machine (with the built in VS web-server and I am an administrator on the network), but when deployed to the IIS 6.0 virtual directory, and run under the Application Pool, it does not work.

  • Dynamically loading JavaScript synchronously

    - by spoon16
    I'm using the module pattern, one of the things I want to do is dynamically include an external JavaScript file, execute the file, and then use the functions/variables in the file in the return { } of my module. I can't figure out how to do this easily. Are there any standard ways of performing a pseudo synchronous external script load? function myModule() { var tag = document.createElement("script"); tag.type = "text/javascript"; tag.src = "http://some/script.js"; document.getElementsByTagName('head')[0].appendChild(tag); //something should go here to ensure file is loaded before return is executed return { external: externalVariable } }

  • How to create digital signature that can not be used to reproduce the message twice

    - by freediver
    I am creating a client-server application and I'd like to send data from server to client securely. Using public/private key algorithms makes sense and in PHP we can use openssl_sign and openssl_verify functions to check that the data came by someone who has the private key. Now imagine that one of the actions sent by server to client is destructive in nature. If somebody uses an HTTP sniffer to catch this command (which will be signed properly) how can I further protect the communication to ensure that only commands coming from our server get processed by the client? I was thinking about using current UTC time as part of the encrypted data but client time might be off. Is there a simple solution to the problem?

  • How to remove characters from a string?

    - by masato-san
    Hi, Below is interview question so you cannot relay on the functions that predefined in libraries. Also my answer below set the element to null but there is another ways to solve the problem. Given string $string = "This is a pen", remove "is" so that return value is "Th a pen" (including whitespece). I've tried (shown below) but returned value is not correct. Thanks in advance! function remove_delimiter_from_string(&$string, $del) { for($i=0; $i<strlen($string); $i++) { for($j=0; $j<strlen($del); $j++) { if($string[$i] == $del[$j]) { $string[$i] = $string[$i+$j]; //this grabs delimiter :( } } } echo $string . "\n"; }

  • Preventing Race Conditions

    - by Qua
    I'm using the built-in ajax functionality of MVC2. Basically the user types a search query, and on every key press a set of results for the query is shown. This works fine in almost all cases, but sometimes the server is a bit slow with a single response, and thus the result for the next key stroke is returned before the previous. When the previous key stroke result set is finally returned to the client it will overwrite the results for the newer search query that should actually have been shown. My code follows more or less along these lines: <% using (Ajax.BeginForm("SearchUser", null, new AjaxOptions() { UpdateTargetId = "findUserResults" }, new { id = "findUserAjaxForm" })) {%> Every keystroke submits this form and thus outputs the results in the 'findUserResults' element. How can I prevent older results from being displayed while still making use of the built-in functions provided in MVC2?

  • Display fraction with numerator/denominator with empty fields for users to enter text

    - by Anil
    Hi all I have a scenario in which I need to design online keyboard with buttons implementing different mathematical functions in ASP.NET. For example 1) A button called "Fraction" Onclicking= should display A numerator and a denominator separated by '-' with empty fields. Just as we write fractions manually. Now when the user clicks on this button the cursor should focus on numerator displaying 'the division line' and then by pressing 'Down' arrow key(on computr keyboard) should focus on denominator allowing users to enter both fields. Keeping it simple the user should be able to toggle between numerator and denominator. Please help me with some sample code. I have got no idea. Thanks in advance

  • How can I use MVC ideas without using classes?

    - by jpjp
    As of right now, I am still shaky on classes, so I don't want to use any classes for my site. I'm still practicing with classes. But how can I implement the MVC idea without classes? Would this work for a MVC? index.php (the view) index_controller.php index_model.php Is this right for what a MVC should be? View: show html, css, forms Controller: get $_POST from forms and any data from the user, get info from db Model: do all the functions, insert/delete in db, etc Basically separate the HTML/css for the view, all the data collecting for the controller, and the logic for the model. And just connect them all using require_once.

  • User management with aspnet membership provider

    - by 109221793
    Hi guys, Just a general question really. I have taken on the management of an application written in C# MVC that uses the asp.net membership api. With this a user can register, change their password, etc. My application consists of two areas, administrator and user. This adminstrator's area has lots of custom admin functionality relating to the application, however has no functionality utilizing the membership api. I want to be able to use the membership api for user management functions such as resetting a password of a user who has forgotten theirs, lock users out, etc. Are there any resources or articles out there that delve into this aspect of using the membership api? Any help would be appreciated :) thanks

  • session_start() Hangs The Server

    - by Narcissus
    Totally confused by this one... We have a WAMPServer installation set up, running a number of virtual hosts from various document roots. Just recently, one particular domain has started hanging the server. We traced it down to session_start(). If we comment it out, there are no problems (except, of course, for the fact that we can't do anything with the session). With it uncommented, it will hang the page load and, with enough reloads, will hang the entire server. All of the other sites still work perfectly with their sessions. As far as I know, there is nothing different with the way sessions are being worked with. I am looking further into it (in case someone changed something) but right now I'm hoping for some direction :) So, any thoughts?

  • Getting Assert to work in Visual C++ Unit Tests?

    - by garsh0p
    I'm using Visual Studio 2008's built in testing framework in my Visual C++ project. I'm adding a new Test Project, then a new Unit Test. However, I can't use any of the functions provided by Assert. Assert shows up in the Intellisense, but I can't do anything with it. I've done unit tests fine in Visual C#. Am I forgetting to do anything? EDIT: There isn't much code because everything I'm doing is auto-generated by Visual Studio 2008. Here are the steps I'm doing: File - New Project - Visual C++ - General - Empty Project Right click solution in Solution Explorer - Add - New Project... Visual C++ - Test - Test Project Open UnitTest1.cpp (auto-generated) Go to TestMethod1() From here, when I try to use the Assert class (like Assert.AreEqual), I can't do it. If I do the same in a Visual C# project, it works fine.

  • Ways not to write function headers twice?

    - by mee
    Hi, I've got a C/C++ question, can I reuse functions across different object files or projects without writing the function headers twice? (one for defining the function and one for declaring it) I don't know much about C/C++, Delphi and D. I assume that in Delphi or D, you would just write once what arguments a function takes and then you can use the function across diferent projects. And in C you need the function declaration in header files *again??, right?. Is there a good tool that will create header files from C sources? I've got one, but it's not preprocessor-aware and not very strict. And I've had some macro technique that worked rather bad. I'm looking for ways to program in C/C++ like described here http://www.digitalmars.com/d/1.0/pretod.html

  • boost::enable_if class template method

    - by aaa
    I got class with template methods that looks at this: struct undefined {}; template<typename T> struct is_undefined : mpl::false_ {}; template<> struct is_undefined<undefined> : mpl::true_ {}; template<class C> struct foo { template<class F, class V> typename boost::disable_if<is_undefined<C> >::type apply(const F &f, const V &variables) { } template<class F, class V> typename boost::enable_if<is_undefined<C> >::type apply(const F &f, const V &variables) { } }; apparently, both templates are instantiated, resulting in compile time error. is instantiation of template methods different from instantiation of free functions? I have fixed this differently, but I would like to know what is up. Thank you

  • Expected Class-name before { token

    - by ML
    Hi All, I am trying to figure out whey I get an error: expected class-name before { token Here is the relative source to the error: #pragma once #ifndef H_FXACTION #define H_FXACTION #include "CP_M_RefCounted.h" #include "FxTypes.h" #include "string" #include "FxString.h" #include "FxPixels.h" #include "CP_Rect.h" #include "FxStreamable.h" #include "FxPoint.h" #include "FxPtr.h" #include "FxImage.h" #include "FxSleekStreaming.h" typedef FxID FxActionType; typedef FxUInt32 FxActionID; FxActionID FrMakeUniqueActionID(void); class FxActionData; class FxActionData : public CP_M_RefCounted { public: FxActionData(); FxActionData(FxBool final) :mFinal(final) { } virtual ~FxActionData(); I get the error at this line: class FxActionData : public CP_M_RefCounted What I dont get is why the line: class FxActionData; is there when you are creating the class directly under it. Isn't this a forward declaration? What things could be going on here?

  • exec() function doesn't rule svn checkout

    - by bahamut100
    Hi, I'm writing some functions in php using exec() to interrogate a svn. The commands exec("svn list ".$myurl) works. Now, I try to get a path on a svn repository with the checkout command. When I put the command "svn checkout http://core.wordress.org/tags/2.9.2/ last-version" directly in the console, it works. But when I do this from a php script using exec(), like this : exec("svn checkout ".$myurl, $dir) it doesn't work. Have you an idea ??

  • Where are the readonly/const in .NET?

    - by acidzombie24
    In C++ you'll see void func(const T& t) everywhere. However, i havent seen anything similar in .NET. Why? I have notice a nice amount of parameters using struct. But i see no functions with readonly/const. In fact now that i tried it i couldnt use those keywords to make a function that promises to not modify a list being passed in. Is there no way to promise the caller that this function will never modify the contents of list? Is there no way to say to call code and say this list should never be modified? (I know i can clone the list or look at documentation but i like compile errors sometime)

  • What are Class methods in Python for?

    - by Dave Webb
    I'm teaching myself Python and my most recent lesson was that Python is not Java, and so I've just spent a while turning all my Class methods into functions. I now realise that I don't need to use Class methods for what I would done with static methods in Java, but now I'm not sure when I would use them. All the advice I can find about Python Class methods is along the lines of newbies like me should steer clear of them, and the standard documentation is at its most opaque when discussing them. Does anyone have a good example of using a Class method in Python or at least can someone tell me when Class methods can be sensibly used?

  • Page inheritance in mixed asp.net Forms and MVC application

    - by Rising Star
    I'm working on a web application. One of my co-workers has written some asp.net forms pages. The page classes all inherit from BasePageClass, which of course inherits from the Page class. I wish to add some MVC controllers that I've been told need to use the same logic implemented in the BasePageClass. Ordinarily, I would want to inherit the functions in the BasePageClass in the controller classes, but this breaks the inheritance heirarchy. What is the best practice for solving this problem?

  • library interposition with dlsym

    - by ZeeGeek
    I'm writing an interposition library to track the usage of some library functions in libc, such as open(), close(), connect(), etc. It works generally well on most of the applications. However, when I try it with PHP, using PHP's MySQL module in particular, none of the function calls to libc inside this module is been tracked (so no connect(), no socket(), etc.). 'strace' told me that the system calls socket(), connect(), etc., took place. Running 'file' on the module and libmysqlclient.so.16.0.0 said that they are all dynamically linked. So it shouldn't be a problem caused by static linkage. What might be the problem? I'm using Fedora 11 64-bit version. Thank you.

  • Powershell equivilent of python's if __name__ == '__main__':

    - by Mark Mascolino
    I am really fond of python's capability to do things like this: if __name__ == '__main__': #setup testing code here #or setup a call a function with parameters and human format the output #etc... This is nice because I can treat a Python script file as something that can be called from the command line but it remains available for me to import its functions and classes into a separate python script file easily without triggering the default "run from the command line behavior". Does Powershell have a similar facility that I could exploit? And if it doesn't how should I be organizing my library of function files so that i can easily execute some of them while I am developing them?

  • Floating point comparison in STL, BOOST

    - by Paul
    Is there in the STL or in Boost a set of generic simple comparison functions? The one I found are always requiring template parameters, and/or instantiation of a struct template. I'm looking for something with a syntax like : if ( is_greater(x,y) ) { ... } Which could be implemented as : template <typename T> bool is_greater(const T& x, const T& y) { return x > y + Precision<T>::eps; }
