  • how to create a https proxy?

    - by davidshen84
    hi, i want to implement a simple ssl web proxy. i do not want to work with the network connection problems. so i think i can utilize a web server (like apache) to help me establish the connection, and my program works like a cgi app on the web server to redirect the web browser request. below is how i want to implement it: client make http/https requests to the target web site, and setting to use my http/https proxy; apache get the request, and use a rewrite rule to redirect the to my cgi app; my app parse the request and make request to the real web site; my app get the response from the real web site, then send the response back to the client; currently, http requests seem to work. but https requests do not work at all. i tried to use curl to make a request to a https web site through my proxy, and the result is CONNECTION FAILED. my question is, will my idea work? if yes, how to make the https requests work.

  • I need to create a contest....

    - by creocare
    I'm working on a contest where users vote for contestants. Each contestant will have a bio. I was wondering what would be the best way to approach this? Should I do this in php or javascript? Should I use a database to collect data? Should I use sqlite3? If I use sqlite3 how do i install that on my mac? I'm very new to all this but I'm a quick learner. Thanks for any advice.

    - by Andrei Tanasescu
    I am building a c# - linq - sql server winforms/asp.net application, accessing a database. I would like my business logic layer to be easily testable, and that means not littering it with Linq database queries everywhere. What design patterns/ best practices are available for the following use cases - inserting/updating a new object - searching for an object - loading a bunch of related data into a sort of "presentation" object that could be displayed by various views ?

  • Create unique file name and fetching it to commandline argument

    - by user343934
    Hi everyone, I am working on python right now and i am little bit stuck in performing some tricks. I have web form with two options- File upload and textarea, i can easily pass file name with file upload options but have problem when it's textarea. Because when i use textarea then first i have to save values passed from textarea to some files and save it on the working directory. After that i can execute commandline argument and pass same saved filename name. For this problem i have to generate unique file first and save the values passed from textarea in it. Can anybody give me some tips to solve my problem. Any algorithms, suggestions and lines of code are appreciated. Thanks for your concern

  • Create a complex SQL query?

    - by mazzzzz
    Hey guys, I have a program that allows me to run queries against a large database. I have two tables that are important right now, Deposits and withdraws. Each contains a history of every user. I need to take each table, add up every deposit and withdraws (per user), then subtract the withdraws from the deposits. I then need to return every user whos result is negative (aka they withdrew more then they deposited). Is this possible in one query? Example: Deposit Table: |ID|UserName|Amount| |1 | Use1 |100.00| |2 | Use1 |50.00 | |3 | Use2 |25.00 | |4 | Use1 | 5.00 | WithDraw Table: |ID|UserName|Amount| |2 | Use2 | 5.00 | |1 | Use1 |100.00| |4 | Use1 | 5.00 | |3 | Use2 |25.00 | So then the result would output: |OverWithdrawers| | Use2 | Is this possible (I sure don't know how to do it)? Thanks for any help, Max

    Let's say I have the following Silverlight Applications: App1.xap App2.xap App3.xap Let's say that I start App1.xap as the default xap file. If I load App2.xap and App3.xap and instantiate an Application class within one of the other two XAPs. The Application.Current changes to be that new instance. System.Windows.Application obj = Activator.CreateInstance(type) as System.Windows.Application; I don't want the current application to change. I just want to get the merged Resource Dictionaries off the Application class.

  • Create word document and add image from .NET app

    - by fearofawhackplanet
    I need a way of generating a word document (from a template or something) and inserting an image at a specific place. Does anyone have any pointers on the best way to do this? I worked on a project that used Office Automation in .NET 1.1 a few years ago, and it was really unspeakably poor. I'm assuming OA has either been improved or been superceeded by a better solution, but I'm not finding much advice on google.

  • How to create DataSource dependency property on a wpf User Control

    - by Michael Hedgpeth
    I have a user control that wraps a grid. I want to be able to set the underlying grid's data source, but through the user control, like this: <my:CustomGrid DataSource="{Binding Path=CollectionView}" /> I have set this up in the grid like this: private static readonly DependencyProperty DataSourceProperty = DependencyProperty.Register("DataSource", typeof(IEnumerable), typeof(CustomGrid)); public IEnumerable DataSource { get { return (IEnumerable)GetValue(DataSourceProperty); } set { SetValue(DataSourceProperty, value); underlyingGrid.DataSource = value; } } But this doesn't work (it doesn't give me an error either). The data source is never set. What am I missing?

  • Using PHP's $_COOKIE to create cookie.txt for cURL

    - by boogie
    Hi, I'm running Drupal and Mediawiki on my server under the same domain. They are connected to each other with extensions/modules. Meaning if I log in to Mediawiki, it automatically logs into Drupal also. Mediawiki has some extensions that filter the information shown on the page. What I want to do is to show that filtered information from Mediawiki on my Drupal page. I'm trying to fetch the data with PHP cURL, but I'm not able to force it to use the login information. How can I convert PHP's $_COOKIE into cURL cookie.txt format? I suppose after that I'm able to fetch the data from Mediawiki with the right permissions. This is what print_r($_COOKIE) outputs: [wiki_session] = gg05lhd6pcfs5g6iokhoo0gue7 [wikiUserName] = WikiSysop [wikiLoggedOut] = 20100510110913 [wikiUserID] = 1 [wikiToken] = 52cdb19a7b4a43e5a2f86939e4f54941 Thanks for any help!

  • Create empty C# event handlers automatically

    - by TomA
    It is not possible to fire an event in C# that has no handlers attached to it. So before each call it is necessary to check if the event is null. if ( MyEvent != null ) { MyEvent( param1, param2 ); } I would like to keep my code as clean as possible and get rid of those null checks. I don't think it will affect performance very much, at least not in my case. MyEvent( param1, param2 ); Right now I solve this by adding an empty inline handler to each event manually. This is error prone, since I need to remember to do that etc. void Initialize() { MyEvent += new MyEvent( (p1,p2) => { } ); } Is there a way to generate empty handlers for all events of a given class automatically using reflection and some CLR magic?

  • Python: Access members of a set

    - by emu
    Say I have a set myset of custom objects that may be equal although their references are different (a == b and a is not b). Now if I add(a) to the set, Python correctly assumes that a in myset and b in myset even though there is only len(myset) == 1 object in the set. That is clear. But is it now possible to extract the value of a somehow out from the set, using b only? Suppose that the objects are mutable and I want to change them both, having forgotten the direct reference to a. Put differently, I am looking for the myset[b] operation, which would return exactly the member a of the set. It seems to me that the type set cannot do this (faster than iterating through all its members). If so, is there at least an effective work-around?

  • Create an object with javascript reflection?

    - by acidzombie24
    I am doing something wrong. At the end of this o is empty. I want to pass in a string such as a=3&zz=5 and do o.a and o.zz to retrieve 3 and 5. How do i generate this object? function MakeIntoFields_sz(sz) { var kvLs = sz.split('&'); var o = new Array(); for (var kv in kvLs) { var kvA = kvLs[kv].split('='); var k = ''; var v = ''; if (kvA.length > 0) { k = kvA[0]; if (kvA.length > 1) v = kvA[1]; o[k] = v; } } return o; };

  • Create categorial variable in R based on range

    - by Stedy
    I have a dataframe with a column of integers that I would like to use as a reference to make a new categorical variable. I want to divide the variable into three groups and set the ranges myself (ie 0-5, 6-10, etc). I tried cut but that divides the variable into groups based on a normal distribution and my data is right skewed. I have also tried to use if/then statements but this outputs a true/false value and I would like to keep my original variable. I am sure that there is a simple way to do this but I cannot seem to figure it out. Any advice on a simple way to do this quickly?

  • Best way to delay access to static web pages until services become available with J2EE

    - by Dean Povey
    I have a J2EE application front-ended by a bunch of GWT pages. When the server is starting up, it is possible that these static pages can be accessed before the services required to implement the GWT RPC calls (database etc) are available. I wondering what the best approach is to prevent a user accessing this static content before these services become available. For the purpose of this exercise, assume that there is an isInitialized() method somewhere. I am happy with either a page displaying an error message or simply refusing the connection.

  • How to create url preview in javascript?

    - by Razor Storm
    Can someone help me with creation of a url preview script in javascript? What I mean is this. Say I have a link on my site, I want the user to be able to mouse over the link, and have an image pop up that shows what the target of the link looks like. Don't worry about the css, I got that working, I just need the actual script to show the image. Currently I am doing it by showing up an iframe that actually renders the page, but this is not scalable and looks ugly. No, having the page display premade images is not an option, since the links will be linking to dynamically generated user content. thanks
