  • Retrieving values from Env in mod_esi or webtools

    - by williamstw
    A complete noob question, but how exactly do I get values (e.g. path_info) from inside the callback? From the docs, I thought it was a list of tuples, which I thought would make it accessible via lists:keyfind, but I've had no luck. So far, all the examples I've found only show how to print everything with io_lib but not how to access the values by key... Thanks, --tim The docs: Module:Function(SessionID, Env, Input)- _ Types SessionID = term() Env = [EnvironmentDirectives] ++ ParsedHeader EnvironmentDirectives = {Key, Value} Key = query_string | content_length | server_software | gateway_interface | server_protocol | server_port | request_method | remote_addr | script_name. <v>Input = string()

  • Inspiration and influence of the else clause of loop statements?

    - by Aristide
    Python offers an optional loop-else clause which is executed if and only if the loop is not terminated by a break. (In other words, the condition fails for a while-loop or the iterator is exhausted for a for-loop.) Does this loop-else construct originate from another language? (Either theoretical or actually implemented.) Has it been taken up in any newer language? Maybe I should ask the former of Guido, but surely he is too busy for such a futile inquiry. ;-) Related discussion and examples: Pythonic ways to use ‘else’ in a for loop

  • Best Ruby ORM for Wrapping around Legacy MSSQL Database?

    - by Technocrat
    Hi. I found this answer and it sounds like almost exactly what I'm doing. I have heard mixed answers about whether or not datamapper can support mssql through dataobjects. Basically, we have an app that uses a consistently structured database, consistently named tables, etc in MSSQL. We're making all kinds of tools and stuff that have to interact with it, some of them remotely and so I decided that we need to create some common, simple access point to do read/write operations on the MSSQL app since it's API is all C# and other things I despise. Now my question is if anyone has any examples or projects they know of where a ruby ORM can essentially create models for another application's legacy database by defining the conventions of each model's pkeys, fkeys, table names, etc. Sequel is the only ORM I've used with MSSQL but never to do anything quite like this. Any suggestions?

  • Dynamically add annotation to an existing class

    - by ng
    I have the following class public class Person { ... } I would like to create another class that would look like this. @SomeAnnotation public class Person { ... } Via a simple method like so. public static Class addAnnotation(Class originalType, Class<? extends Annotation> annotation) { // what goes here? } Is there an easy way to do this via ASM for example? What dependencies would I need. I have tried to Google this however the examples I have found are either incomplete or are doing something else. Other frameworks such as javassist would be just as good.

  • How to use a value from one stored procedure in another?

    - by RoguePlanetoid
    I have the following statement in a Stored Procedure: DECLARE @Count INT EXEC @Count = GetItemCount 123 SELECT @Count Which calls another stored procedure with the following statement inside: SELECT COUNT(Item) FROM tblItem WHERE ID = @ID However when I test the call the EXEC outputs the value correctly but it is not assigned to the @Count Variable correctly. I've seen examples or stored procedures used like this, including here but none had a parameter and a return value used (that I could find). The ID Parameter is passed into the second statement which returns a count value used by the first StoredProcedure - all the info I have read seems to indicate this should work - but it doesn't the @Count value is aways zero, even when the GetItemCount returns always the correct value. This is in Microsoft SQL Server 2008 if that helps.

  • BCB: how to get the (approximate) width of a character in a given TFont?

    - by mawg
    It's a TMemo, not that that should make any difference. Googling suggests that I can use Canvas->TextWidth() but those are Delphi examples and BCB doesn't seem to offer this property. I really want something analogous to memo->Font->Height for width. I realize that not all fonts are fixed width, so a good estimate will do. All that I need is to take the width of a TMemo in pixels and make a reasonable guess at how many characters of the current font it will hold. Of course, if I really want to be lazy, I can just google for the average height/width ratio, since height is known. Remember, an approximation is good enough for me if it is tricky to get exact. http://www.plainlanguagenetwork.org/type/utbo211.htm says, " A width to height ratio of 3:5 (0.6) is recommended for most applications"

    Is there a way to return the users location as a string from a model? I have a model thats job is to download same JSON data from a web service. When sending in my request I need to add ?lat=LAT_HERE&lng=LNG_HERE to the end of the string. I have seen tons of examples using the map or constantly updating a label. But I cant find out how to explicitly return the lat and lng values. Im only 2 days into iPhone dev so go easy on me :)

  • Using Selenium 2's IWebDriver to interact with elements on the page

    - by Andreas Grech
    I'm using Selenium's IWebDriver to write Unit Tests in C#. Such is an example: IWebDriver defaultDriver = new InternetExplorerDriver(); var ddl = driver.FindElements(By.TagName("select")); The last line retrieves the select HTML element wrapped in a IWebElement. I need a way to simulate selection to a specific option in that select list but I can't figure out how to do it. Upon some research, I found examples where people are using the ISelenium DefaultSelenium class to accomplish the following, but I am not making use of this class because I'm doing everything with IWebDriver and INavigation (from defaultDriver.Navigate()). I also noticed that ISelenium DefaultSelenium contains a ton of other methods that aren't available in the concrete implementations of IWebDriver. So is there any way I can use IWebDriver and INavigation in conjunction with ISelenium DefaultSelenium ?

  • Retrieving content of a txt file from URL to Android

    - by eightx2
    I would like to be able to retrieve contents of a .txt file from the internet, and load it in an EditText. I tried using the code on this page: Reading Text File From Server on Android It didn't work, as you might have guessed. I've read on numerous sites about this type of problem, but I can't get anything to work. Someone suggested AndroidHttpClient (http://developer.android.com/reference/android/net/http/AndroidHttpClient.html), but I simply can't find any examples with this. As I'm a newbie in Android programming, I would love if someone could please give me a small example.

  • Creating a User Registration Page using MongoEngine

    - by Drew Watkins
    I am currently working an a webapp, using mongoengine and django, which will require users to create an account from a registration page. I know MongoEngine has an authentication backend, but does it also include a registration form, etc..., like django itself does? If not, are there any example projects which show how to implement this? The only open-source mongoengine project I've found is django-mumblr, but I can't find the examples I want in it. I'm not interested in alternative options, such as MongoKit or mango for handling authentication. I am just getting started with django and mongoDB, so please excuse my lack of knowledge. Thanks in advance for the help!

  • What's quicker and better to determine if an array key exists in PHP?

    - by alex
    Consider these 2 examples $key = 'jim'; // example 1 if (isset($array[$key])) { doWhatIWant(); } // example 2 if (array_key_exists($key, $array)) { doWhatIWant(); } I'm interested in knowing if either of these are better. I've always used the first, but have seen a lot of people use the second example on this site. So, which is better? Faster? Clearer intent? Update Thanks for the quality answers. I now understand the difference between the 2. A benchmark states that isset() alone is quicker than array_key_exists(). However, if you want the isset() to behave like array_key_exists() it is slower.

  • Can Grails exceptionHandler support the following Error Handling Flow

    - by Andrew
    In my rails app that I am porting to grails whenever an unexpected error occurs I intercept the error automatically and display a form to the user informing them that an error has occured and asking them for further information. Meanwhile, as the form is rendered I write the stack trace and other information about who was logged in to a database table. Then if the form is submitted I add that information to the error report. I cannot tell from the exceptionHandler documentation and BootStrap examples whether that will allow me to grab all the information including various session and request parameters and then stuff them into a database and then post a form. Any thoughts?

  • execute javascript function in a another iframe when parent is from different domain.

    - by Frushko
    The page A.com has 2 iframes B.com/page1 and B.com/page2. This is the code of A.com: <html><body> <iframe src="b.com/page1" name="iframe1" id="iframe1"> <iframe src="b.com/page2"> </body></html> I want to execute js function on B.com/page1 from B.com/page2. Both examples below works well when the parent is from the same domain but not in cross domain scenario: parent.window.frames['iframe1'].SomeFunction(args); or parent.document.getElementById('iframe1').contentWindow.SomeFunction(args); Is there any way to do it?

  • Sorting issues in flexigrid with "json" data

    - by John Sieber
    I'm currently using flexigrid to display data in a current project, but am running into issues with its ability to properly sort certain columns that contain dates or numbers. The data is being sent from a ColdFusion CFC that selects the appropriate data and then delivers it in the proper "json" format. As the date/time stamps and other fields containing numbers are sent as "strings" they do not sort properly in the data grid. Is this a limitation of Flexigrid or am I sending the data improperly to Flexigrid? I can provide examples of my code if that is helpful.

  • Agile web development with Rails 4 interface difficulties

    - by Luke Annison
    I've been following along with the examples in the book in making a online catalog and am having a couple of discouraging difficulties in Chapter 8 task C: Catalog display. I have input the code for the stylesheets as instructed but it has created a slightly skewed result as compared to what is shown in the book. Whilst minor and aesthetic in nature its a little shock to my confidence and slightly irritating when trying to carry on through the book. I have too little rep to post a pic, but heres the link: http://s11.postimage.org/3pwlzfiwj/Screen_Shot_2012_10_08_at_22_29_56.png) As you can see the boarder seems a little confused and the image at the top is covering the header text. I've been through the code time and time again but can't seem find out where I've gone wrong. Could anybody give me some clues?

  • How do you check individual SqlCommands ran during a SqlTransactions to see if they will run?

    - by Sam F
    I've been reading up on SqlTransactions and have found a great load of examples like: http://www.devhood.com/tutorials/tutorial_details.aspx?tutorial_id=451 The problem is, when I do a BeginTransaction() (Execute all the commands) and then Commit() at the end all the commands I execute get run and the ones with syntax errors or other errors just get skipped. This is where I would also like to run a roll back, not skip over them. I found a few articles on the subject but they were not very helpful and purely in SQL. Is there any way to find out if one of the ExecuteNonQuery()'s failed before the commit and not just skipped? Thanks.

  • A good F# codebase to learn from

    - by Lucas
    Hi all, I've been teaching myself F# for a while now. I've read Programming F# by Chris Smith (great book) and I've written a few small scripts for getting the job done here and there. But IMO the best way to learn a new programming language—and more importantly, the idioms that come with it—is to read a good open source codebase written in that language. Naturally, writing code in that language is crucial, but in the beginning, you're basically struggling with your own ignorance about how things should be done. You could perform certain tasks one way or the other, but it takes experience to realize the flaws and virtues of each. Even after you've gotten a firm grasp of how things work, reading the code of people who have an even firmer one helps a great deal. Most would agree that the most insightful parts of any learn-a-programming-language book are the code examples, and reading a well-written open source codebase is the next level of that. So are there any out there for F#?

  • 3 fixed Columns (header and footer) using DIVs, NO Absolute DIVs, IE friendly, ALL columns stretch e

    - by Phillip Schein
    Left to right, Col1 id 560px wide with 10 px padding, middle column, 250px wide with 5px padding and Col3 (siderbar) is 200px wide with 3px padding. Background coloR, no matter text length in any column should stretch vertically equal. No javascript (jQuery workarounds) to make it work. It needs to be pure Semantic Markup with CSS. Each Column should have a nested column of color were content will go. Column 1 should be SEO prominant which means the highest nested column for Google and other Search Engines to crawl. I have used 'The Holy Grail" layout, articles at "A List Apart" and these solution are so convoluted that they push the main columns left and than the nested columns push them with padding back right. This is crazy! I try to adjust these examples, but they're not editable by just adjusting a width in the CSS or the padding, etc. Can you please help me?

  • Doctrine 1.2 Column Naming Conventions for Many To Many Relationships

    - by Alan Storm
    I'm working with an existing database schema, and trying to setup two Doctrine models with a Many to Many relationship, as described in this document When creating tables from scratch, I have no trouble getting this working. However, the existing join tables use a different naming convention that what's described in the Doctrine document. Specifically Table 1 -------------------------------------------------- table_1_id ....other columns.... Table 2 -------------------------------------------------- table_2_id ....other columns.... Join Table -------------------------------------------------- fktable1_id fktable_2_id Basically, the previous developers prefaced all forign keys with an fk. From the examples I've seen and some brief experimenting with code, it appears that Doctrine 1.2 requires that the join table use the same column names as the tables it's joining in Is my assumption correct? If so, has the situation changed in Doctrine 2? If the answers to either of the above are true, how do you configure the models so that all the columns "line up"

  • How can I deal with the ICE60 warning in WiX?

    - by Scott Boettger
    Good Afternoon, I have created a WiX project that installs a bunch of different EXEs and DLLs. Unfortunatly when I build the project I receive the following warning for each one of them: ICE60: The file fileName is not a Font, and its version is not a companion file reference. It should have a language specified in the Language column. I have found examples and possible solutions for this and each time it is suggested to set the DefaultLanguage tag to 0 in order to fix the warning. Once doing that I then get this warning: The DefaultLanguage '0' was used for file 'fileName' which has no language or version. For unversioned files, specifying a value for DefaultLanguage is not neccessary and it will not be used when determining file versions. Remove the DefaultLanguage attribute to eliminate this warning. So this leads me to the question of how can I handle this warning? Thanks in advance for any and all help given.

  • Can I access an iframe of the same domain in a separate window?

    - by jozecuervo
    How can I detect the presence of and then call a function on a frame that is already loaded in one tab (my iframed facebook app) from a page being loaded in a new tab (from an ad-served link). It seems most examples focus on parent/child iframe communication. In this case, a link will be served from Google Ad Manager, which only allows _top or _blank to be targeted. I want to pass an id through the ad click into the new page/tab on my domain and then JS call over to the frame my app is in to switch state. Both frames are on my domain but not in the same document or window. Is this possible?

  • Is it possible to start an activity in a different apk using startActivity on Android using the acti

    - by icecream
    I have tried to write an Android application with an activity that should be launched from a different application. It is not a content provider, just an app with a gui that should not be listed among the installed applications. I have tried the code examples here and it seems to be quite easy to launch existing providers and so on, but I fail to figure out how to just write a "hidden" app and launch it from a different one. The basic use case is: App A is a normal apk launchable from the application list. App B is a different apk with known package and activity names, but is is not visible or launchable from the application list. App A launches app B using the package and class names (or perhaps a URI constructed from these?). I fail in the third step. Is it possible to do this?

  • Using variables in Tasker

    - by Waza_Be
    I am trying to create a Tasker plugin. Everything is fine, and works pretty well. I can configure a String to be sent in my app by using EditActivity and this code, following the examples: resultIntent.putExtra(com.twofortyfouram.locale.Intent.EXTRA_BUNDLE,PluginBundleManager.generateBundle(getApplicationContext(),message)); resultIntent.putExtra(com.twofortyfouram.locale.Intent.EXTRA_STRING_BLURB,generateBlurb(getApplicationContext(), message)); setResult(RESULT_OK, resultIntent); The problem comes when I want to use this code to get the battery level for instance, so I added: resultIntent.putExtra("net.dinglisch.android.tasker.extras.VARIABLE_REPLACE_KEYS",com.twofortyfouram.locale.Intent.EXTRA_STRING_BLURB); but the app is not working and I get a string %BATT as the result, the variable is not replaced... As I haven't found any example, I would be pleased to get some help to make it work.

  • iPhone audio Filter Question

    - by Joe
    Okay, I am going to try to make this totally not a "plz send teh codez kthxbai" I am considering an app which takes sound (eventually an audio track) and applies an audio filter to it. So I can play sounds with AudioServicesPlaySystemSound via AudioToolbox framework just fine. What I need is a very simple example of how I might take a sound and apply (for instance) midrange boost etc. Actually the kind of alteration is irrelevant -- if I can get my head around how the alteration is done I can figure out the rest. I am just finding both docs and examples of altering audio in code to be very scarce. Thanks for any help!
