• How to test a .net application against a proxy?

  - by Pierre-Alain Vigeant

  I need to support the use of proxy on our application that is using WCF connections. We do not have any proxy server on our network and I don't want to disrupt our corporate network by requesting a proxy installation. I was thinking of installing a proxy server on a local virtual machine and configurating Internet Explorer so that it will challenge that proxy. I don't know what proxy software to use (I don't want to install ISA server) and I don't know how to configure one. Does someone have any suggestion for a easy to use software that will require an authentication for any WCF services and do you have any guideline that would be helpful to know when testing a software against a proxy?

• How do I send data from Java to Flash locally?

  - by terence

  I have a website with a Java applet and a Flash application. I want the Java applet to send data to the Flash application locally. What's the best way to do this? The data I want to send are potentially large images (possibly up to 1MB in size). This means sending a base64 string to javascript and then to Flash would probably be too cumbersome. I don't want to have to contact external servers or anything; all of it should be possible locally and offline. Is there some easy way to just send this sort of data around? If I saved the file locally first, Flash wouldn't be able to access that, would it?

• How to override JS function from a firefox extension?

  - by BruceBerry

  Hello, I am trying to intercept calls to document.write for all pages. Setting up the interception inside the page by injecting a script like function overrideDocWrite() { alert("Override called"); document.write = function(w) { return function(s) { alert("special dom"); w.call(this, wrapString(s)); }; }(document.write); alert("Override finished"); } is easy and works, but i would like my extension to setup the interception for each document object from inside the extension. I couldn't find a way to do this. I tried to listen for the "load" event and set up the interception there but it also fails. How do I hook calls to doc.write from an extension?

• Automating site interaction

  - by Leocer

  I'm working with a CMS and need to import data to it using typical html forms. The data itself is in csv files with one page per row. Such is the CMS that importing directly to db isn't possible due to the complexity of the design. It's pretty important that i "fake" usual user interaction because the CMS does a lot of background work that's crucial for the import. Basically, for each row in the csv file, I need to copy a csv column to a html textfield, or select a checkbox, or click a certain button. One major issue is mapping the data in the csv to actions in the CMS. So if one column contains the string 'foobar' is really means "set the firstName dropdown widget to 'foobar'". Is there a tool to automate this? I´ve been looking at AutoHotKey, Selendium, Web-Harvester and many other tools but I'm not convinced they are the correct tools. The main problem is being able to interact with the html pages in a easy way.

• mysql eliminate responses under certain condition with join

  - by Dustin

  Forgive me if this is an easy question. I teach classes and want to be able to select those students who have taken one class, but not another class. I have two tables: lessons_slots which is the table for every class such as: -------------------- -ID name slots- -1 basics 10 - -2 advanced 10 - -3 basics 10 - --------------------- The other table is class_roll, which holds enrollment info, such as: -------------------- -sID classid firstname lastname- -1 1 Jo Schmo -2 1 Person Two ... -13 2 Jo Schmo --------------------- What I want to do, I select everyone who has not had the advanced class (for example). I've tried doing SELECT * FROM lessons_slots LEFT JOIN class_roll ON lessons_slots.ID = class_roll.classid WHERE lessons_slots.name != 'advanced' But that doesn't work. Any ideas?

• php mail function cannot send to [email protected] ??i

  - by user333216

  I'm having trouble when sending emails thorough the mail() function. I have a script that works perfectly fine for an email address like [email protected] but when the first part of the email is something with a dot like [email protected] it doesn't work and returns this error : Warning: mail() [function.mail ]: SMTP server response: 554 : Recipient address rejected: Relay access denied in confirmed.php on line 119 I am using real email address but have changed it in the above example. Any thoughts - I'm not a php master but surely there is an easy way to send emails to address with a 2 part first section?? Thanks in advance Ali

• Error safe/correcting resource identifier

  - by Martin

  The receiver is my website, the sender is the same but the medium is noisy, a user. He will read an alphanumeric code of length 6 and later input the same code to identify a resource. A good use for a error correcting code, I thought, and rather than do the research I thought I'd just put the question out there. Or I might be going about it the wrong way, since the situation is rather like sending a perfect dictionary along with every transmission. The requirements on the code are simply: 6 alphanumeric digits, to start with until I run out, anyway. If the user gets it wrong I should still be able to identify the right resource. No resource is preferable to the wrong one. Easy to code or have free libraries for .net Any suggestions?

• How to write an editor that shows the content of a folder in eclipse?

  - by tangens

  Motivation I have written an eclipse plugin that shows me a list of all files and folders with unreviewed content. When selecting a folder, I want an editor to open showing all files and subfolders that this folder contains. It has to work for versioned items, too. So I have to create the content of the editor within my plugin (no backing IResource). What I currently have Right now I'm opening a RemoteFileEditorInput for a versioned file (subclipse) or I'm using IWorkbenchPage.openEditor() for a FileEditorInput. Question What's an easy way to visualize dynamic content (directory listing) inside of an text editor?

• Get local network interface addresses using only proc?

  - by Matt Joiner

  How can I obtain the (IPv4) addresses for all network interfaces using only proc? After some extensive investigation I've discovered the following: ifconfig makes use of SIOCGIFADDR, which requires open sockets and advance knowledge of all the interface names. It also isn't documented in any manual pages on Linux. proc contains /proc/net/dev, but this is a list of interface statistics. proc contains /proc/net/if_inet6, which is exactly what I need but for IPv6. Generally interfaces are easy to find in proc, but actual addresses are very rarely used except where explicitly part of some connection. There's a system call called getifaddrs, which is very much a "magical" function you'd expect to see in Windows. It's also implemented on BSD. However it's not very text-oriented, which makes it difficult to use from non-C languages.

• Can LGPL licenses be used in our proprietary systems?

  - by jon

  We want to use either the FCK/CKeditor or the TinyMCE editor in our CRM application. We charge the customer use of the CRM system which is bespoke to use and them. I noticed both the editors have GPL and LGPL licenses. However CKEditor has a Closed License too in addition to the LGPL. My questions are: 1) Although we don't sell our code or binaries, we provide software as a hosted service, can we use LGPL licenses? 2) Why does CKEditor provide LGPL and Closed licenses if the LGPL should make it easy for any proprietary software to use it? Is it only for systems which are sold as a binary where the product is for example physically installed as an .exe?

• Are there any programming languages targeting PHP, besides haXe?

  - by stesch

  PHP doesn't get much love but is still a winner at easy deployment (for cheap hosting). Are there any programming languages (besides haXe) that target PHP? Writing applications in this language and then translating it into PHP, like some languages target C as an intermediate language? The Scheme implementation Chicken compiles into C. XOTcl converts Java code into Tcl code LINJ was(?) a tool to convert Lisp into nice looking Java code … + a lot of ways to produce JavaScript without touching JavaScript.

• Override An Existing Property as a Child form of its return type

  - by Jason

  I apologize if that title is confusing. This question may be a result of lack of coffee and/or sleep, but my mind is not working correctly right now. Anyways, I have an inheritance tree like such (I know the architecture isn't ideal): BaseClass GeneralForm : Inherits BaseClass SpecificForm : Inherits GeneralForm And an object like so: MyItem MySpecificItem : Inherits MyItem I have Items As List (Of MyItem) as a property in BaseClass. I would like for SpecificForm to somehow override Items to return type List (Of MySpecificItem). I feel like this is easy to do, but again, my head is spinning and I can't think straight at the moment. Thank you so much in advance.

• How to grab the lines AFTER a matched line in python

  - by toofly

  Hi All, I am an amateur using Python on and off for some time now. Sorry if this is a silly question, but I was wondering if anyone knew an easy way to grab a bunch of lines if the format in the input file is like this: " Heading 1 Line 1 Line 2 Line 3 Heading 2 Line 1 Line 2 Line 3 " I won't know how many lines are after each heading, but I want to grab them all. All I know is the name, or a regular expression pattern for the heading. The only way I know to read a file is the "for line in file:" way, but I don't know how to grab the lines AFTER the line I'm currently on. Hope this makes sense, and thanks for the help!

• Make a Method of the Business Layer secure. best practice / best pattern [.net/c#]

  - by gsharp

  Hi We are using ASP.NET with a lot of AJAX "Page Method" calls. The WebServices defined in the Page invokes methods from our BusinessLayer. To prevent hackers to call the Page Methods, we want to implement some security in the BusinessLayer. We are struggling with two different issues. First one: public List<Employees> GetAllEmployees() { // do stuff } This Method should be called by Authorized Users with the Role "HR". Second one: public Order GetMyOrder(int orderId) { // do sutff } This Method should only be called by the owner of the Order. I know it's easy to implement the security for each method like: public List<Employees> GetAllEmployees() { // check if the user is in Role HR } or public Order GetMyOrder(int orderId) { // check if the order.Owner = user } What I'm looking for is some pattern/best practice to implement this kind of security in a generic way (without coding the the if then else every time) I hope you get what i mean :-) Thanks for you help.

• Flex Framework vs. Micro-Architecture

  - by droboZ

  I'm in the process of choosing a framework for my flex development, and one of the questions that was asked about a framework was "is this a framework or a micro-architecture"? Can someone clarify what's the difference? What exactly is a framework, and when can we start calling what we have a framework? I work with FlexBuilder3 (now called FlashBuilder4) and have a lot of standard things that I do for almost all projects, and components that I created for easy re-use. Some are very very small, but the benefit of a 1-liner has been immense for me instead of repeating the code over and over. So in the framework/micro-architecture scheme, can I say that these are my internal in-house framework or are they part of a micro-architecture? Trying to understand this topic better.

• Proper design a Model-Controller in Cocoa?

  - by legege

  Hi, I'm trying to design a simple Cocoa application and I would like to have a clear and easy to understand software architecture. Of course, I'm using a basic MVC design and my question concerns the Model layer. For my application, the Model represents data fetched on the Internet with a XML-RPC API. I'm planning to use Core Data to represent a locally fetched version. How should the data be loaded initially? I'm reading the Cocoa Design Pattern book, and they talk about a Model-Controller that is centric to the Model. How would that be done? Thanks!

• R: including model specifications in xtable(anova(...))

  - by HamiltonUlmer

  Hello R comrades: I have a bunch of loglinear models, which, for our purposes will just be glm() objects called mx, my, mz. I want to get a nicely-formatted xtable of the analysis of deviance, so naturally I would want to perform xtable(anova(mx, my, mz, test = "Chisq")). The vanilla output of xtable, however, doesn't include the model specifications. I'd like to include those for all the ANOVA tests I'm running, so if there is not a param I'm missing that does this I'll probably just have to hack up my own solution. But looking over the help page, there doesn't seem to be an easy way to include the model specifications. Any thoughts? Alternatives? If it helps this was done in 2.9.1 with xtable 1.5-5.

I tried to use tag or tabindex property but I don't find the good way to proceed .... Is someone know an easy way to solve this !!! Thanks

• alter mysqldump file before import

  - by julio

  Hi-- I have a mysqldump file created from an earlier version of a product that can't be imported into a new version of the product, since the db structure has changed slightly (mainly altering a column that was NOT NULL DEFAULT 0 to UNIQUE KEY DEFAULT NULL). If I just import the old dump file, it will error out since the column that has default values of 0 now breaks the UNIQUE constraint. It would be easy enough to either manually alter the mysqldump file, or import into a temp table and change it, then copy to the new table. However, is there a way to do this programatically, so it will be repeatable and not manual? (this will need to happen for many instances of this product). I'm thinking something like disabling key constraints for the import, then setting all values that = 0 to NULL, then re-enabling the key constraints? Is this possible? Any help appreciated.

• How to use a servlet to repsond to a request for an object

  - by Rick

  I'm sure this is easy, but I don't work with website development very often and I'm lost on this one. I have a web application that needs to support multiple clients with different settings, icons and other content. The contents of these files are in separate directories for each client. What I would like to do is respond to a request sent to a jsp/java servlet. The servlet will look up the proper folder location in a database (I have the database stuff working) and send the actual object to the requesting page whether it is xml, graphic or video. How do I do that? What methods should I be using. Help I'm lost! :(

• Python method to remove iterability

  - by Debilski

  Suppose I have a function which can either take an iterable/iterator or a non-iterable as an argument. Iterability is checked with try: iter(arg). Depending whether the input is an iterable or not, the outcome of the method will be different. Not when I want to pass a non-iterable as iterable input, it is easy to do: I’ll just wrap it with a tuple. What do I do when I want to pass an iterable (a string for example) but want the function to take it as if it’s non-iterable? E.g. make that iter(str) fails.

• Accessing wrapped method attribute in C#

  - by prostynick

  I have following code: public static void ProcessStep(Action action) { //do something here if (Attribute.IsDefined(action.Method, typeof(LogAttribute))) { //do something here [1] } action(); //do something here } For easy use I have some similar methods using method above. For example: public static void ProcessStep(Action<bool> action) { ProcessStep(() => action(true)); //this is only example, don't bother about hardcoded true } But when I use the second method (the one above), even if original action had attribute, code [1] will not be executed. How can I find if method is only wrapper and underlying method contains attribute and how to access this attribute?

• Android ListView highlight multiple items

  - by Tobias Kuess

  I want my ListView to change its background for each selected item (Multi-Selection). I used this code: <ListView ... android:drawSelectorOnTop="false" android:listSelector="@android:color/darker_gray" > This works fine, but it is just possible to select one single item of the list. If I select another one the selection is resetted and the new one changes its background. Is there an easy and fast way to make it possible to select more than one item at the same time with changing the background of every selected item?

• Documents stored in SQL table

  - by vradenburg

  I have a legacy FoxPro application which stores documents in an SQL table in a field with the image datatype. FoxPro accesses the image datatype as a "General" field which can be used to store various files. I have a FoxPro control which interfaces with the General field for modifying/viewing the document that was stored. I need to migrate this control to .NET and make it easy for users to view/modify documents of various types. Does anyone have any suggestions on some ways to go about this or know of things that I'll need to consider for the migration to .NET? I'm pretty sure that I'll need to migrate the field to either a varbinary(max) or FileStream data type.
