  • Reading a memorystream

    - by user1842828
    Using several examples here on StackOverflow I thought the following code would decompress a gzip file then read the memory-stream and write it's content to the console. No errors occur but I get no output. public static void Decompress(FileInfo fileToDecompress) { using (FileStream originalFileStream = fileToDecompress.OpenRead()) { string currentFileName = fileToDecompress.FullName; string newFileName = currentFileName.Remove(currentFileName.Length - fileToDecompress.Extension.Length); using (FileStream decompressedFileStream = File.Create(newFileName)) { using (GZipStream decompressionStream = new GZipStream(originalFileStream, CompressionMode.Decompress)) { MemoryStream memStream = new MemoryStream(); memStream.SetLength(decompressedFileStream.Length); decompressedFileStream.Read(memStream.GetBuffer(), 0, (int)decompressedFileStream.Length); memStream.Position = 0; var sr = new StreamReader(memStream); var myStr = sr.ReadToEnd(); Console.WriteLine("Stream Output: " + myStr); } } } }

  • API verbs for an interruptible operation

    - by 280Z28
    I have a long running task as part of my application. The task can be started, paused, resumed, and cancelled. I'm trying to find the best interface for these operations. Two seem clear: Pause and Cancel. This leaves the start and resume operations. I could include both Start and Resume. This has the downside of either requiring the API consumer to check the state before starting/resuming the operation to call the right method, or making the methods aliases of each other. I'm thinking I should include either Start or Resume, but I don't know which one is the most appropriate. Does anyone have any examples in the .NET Framework of such behavior? I prefer to follow established patterns whenever they are available.

  • Do you use Phing?

    - by Sam McAfee
    Does anyone use Phing to deploy PHP applications, and if so how do you use it? We currently have a hand-written "setup" script that we run whenever we deploy a new instance of our project. We just checkout from SVN and run it. It sets some basic configuration variables, installs or reloads the database, and generates a v-host for the site instance. I have often thought that maybe we should be using Phing. I haven't used ant much, so I don't have a real sense of what Phing is supposed to do other than script the copying of files from one place to another much as our setup script does. What are some more advanced uses that you can give examples of to help me understand why we would or would not want to integrate Phing into our process.

  • What's the difference between /123 and /?123?

    - by BoltClock
    I've noticed that some sites (including http://jobs.stackoverflow.com) have query strings that look like this: http://somewebapp.example/?123 as compared to: http://somewebapp.example/123 or http://somewebapp.example/id/123 What are the reasons that developers choose to implement their web apps' URLs using the first example instead of the second and third examples? And as a bonus, how would one implement the first example in PHP, given that 123 is the primary key of some row in a database table? (I just need to know how to retrieve 123 from the URL; I already know how to query the database for a primary key of 123.)

  • How do I get a title or some text to appear in a Silverlight mediaplayer when switching to FullScree

    - by Matt
    I am working on an ASP.NET website with VB.NET code-behind. I have a Silverlight mediaplayer object on one of the pages and the user may view that video in FullScreen mode. When changing to full-screen mode they are losing the title and chapter of the video series they are viewing. I have tried accessing properties and searched the web for examples on how I could put a title or some text over the player when in FullScreen mode to give the user an indication of where they are currently at while viewing each video. I am using OnClientMediaEnded to move through the videos after each video has ended so they are able to watch the whole series once in FullScreen mode. I am using a call to javascript in with this method to do that and want to know if there is any way to get a title or text up there and then change once the video switches to the next in the series? The controls on the player also go away when going into FullScreen mode so any help with that would be greatly appreciated as well. Thanks

  • How can i connect two or more machines via tcp cable to form a network grid?

    - by Gath
    How can i connect two or more machines to form a network grid and how can i distribute work load to the two machines? What operating systems do i need to run on the machines, and what application should i use to manage the load balancing? NB: I read somewhere that google uses cheap machines to perform this fete, how do they connect two network cards( 'Teaming' ) and distribute load across the machines? Good practical examples would serve me good, with actual code samples. Pointers to some good site i might read this stuff will be highly appreciated.

  • Confusion with cookie session token and oauth2.0 don't know where to go anymore

    - by byte_slave
    Hi guys, I'm completely confused, frustrated and nothing seems to make sense and work any more. I' dev some iframe fb app and i've been using the javascript sdk (FB.Init()) to get the access_token, but doesn't always work, sometimes i'm already logged into FB and doesn't works... Did some reading, and read also that there is problems using cookies in iframes in Opera and IE, so I was thinking in use the OAuth 2.0 but i'm not sure how via facebook sdk c# and now I'm now completely lost, don't know if i still need to use the javascript FB.Init(). Documentation out there is poor and unclear, a lot of stuff refers to old code, and after hours of reading, jumping on examples, i'm completely messed up and confused. Can some, please, point/explain/enlightening me about this? Thanks a lot guys, appreciated! Merry christmas!

  • Hot to log in to a website using installed twill?

    - by brilliant
    Hello, everybody!!!! I have just successfully installed TWILL on my computer with the help of one very supportive member of "StackOverflow" (you can check it out HERE) and have tried to run one of the simple examples on the twill documentation page (you can see that page HERE). Here is that example: Let's say my username on www.slash.org is lynxye and my password is mammal. When I try to enter that exanple code into my Python prompt, I can only enter the first line of the code bexcause when I click on "Enter" to start a new line, I get some error messages right away: The same happens when I try to enter this code into my terminal: I think I miss out on some basics here. Perhaps, I need to create a file that would contain that code and then run that file somehow, but I really don't know where I need to create that file and with what extensdion. Can anyone, please, help me with this?

  • DrawRect on the iPhone vs. the Mac

    - by Joe Cannatti
    I am an experienced iPhone dev beginning to work on my first Mac app. One thing that is really throwing me off is the differences between UIView and NSView. It seems that I cannot set the background color of a NSView via interface builder as I can with a UIView. It also seems that I cannot do it by simply sending a setBackgroundColor: message to it. All the examples I have seen are overriding drawRect: in a subclass of NSView. Is that really the only way to do it? What is the conceptual difference here, and why is it this way? NOTE: I am only trying to set the background color to the default grey.

  • 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

  • Another Permutation Word Conundrum... With Linq?

    - by CraigF
    I have seen many examples of getting all permutations of a given set of letters. Recursion seems to work well to get all possible combinations of a set of letters (though it doesn't seem to take into account if 2 of the letters are the same). What I would like to figure out is, could you use linq (or not) to get all possible combinations of letters down to 3 letter combinations. For example, given the letters: P I G G Y I want an array of all possible cominations of these letters so I can check against a word list (scrabble?) and eventually get a list of all possible words that you can make using those letters (from 3 letters up to the total, in this case 5 letters).

  • 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()

  • CakePHP hasOne ineffeciency?

    - by Andre
    I was looking at examples on the CakePHP website, in particular hasOne used in linking models. http://book.cakephp.org/view/78/Associations-Linking-Models-Together My question is this, is CakePHP using two queries to build the array structure of data returned in a model that uses hasOne linkage? Taken from CakePHP: //Sample results from a $this-User-find() call. Array ( [User] => Array ( [id] => 121 [name] => Gwoo the Kungwoo [created] => 2007-05-01 10:31:01 ) [Profile] => Array ( [id] => 12 [user_id] => 121 [skill] => Baking Cakes [created] => 2007-05-01 10:31:01 ) ) Hope this all makes sense.

  • Web Form based login in Java

    - by BrunoLM
    How can I block access to the site if a user is not logged in? Under web.xml Security I checked Form authentication then I selected Login and Error page, but I don't know how to block the access and redirect the user to the login page. Do I need a filter? If so, how can I get the login url I specified? And how should I call the validation method? I saw in some examples this code <form method=post action="j_security_check"> <input type="text" name="j_username" /> <input type="password" name="j_password" /> </form> What does it do?

  • Working with Form Array's in Coldfusion?

    - by Jakub
    I have no idea how to handle this in coldfusion 9, I have a form being submitted (POST) with element checkboxes, called items[]. When I do a <cfdump var="#form#" /> no-problem, I get all the items shown with the proper names like items[] eg: struct ITEMS[] 13,14 FIELDNAMES ITEMS[] however doing a <cfdump var="#form.items[]#" /> results in an error. How do I access the CF9 field values? Somehow loop through it? I cannot seem to do anything with the array to get the id's out of it? Thoughts, I'm kindof stumped and coldfusion isn't the easiest language to find examples / references on the net ;) Is there a correct way to deal with this? I need to get the ID's out of there so I can referenc what lines were checked in the form, so I can follow up with an action. Thanks!

  • 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.

  • Code Golf: Ghost Leg

    - by Anax
    The challenge The shortest code by character count that will output the numeric solution, given a number and a valid string pattern, using the Ghost Leg method. Examples Input: 3, "| | | | | | | | |-| |=| | | | | |-| | |-| |=| | | |-| |-| | |-|" Output: 2 Input: 2, "| | |=| | |-| |-| | | |-| | |" Output: 1 Clarifications Do not bother with input. Consider the values as given somewhere else. Both input values are valid: the column number corresponds to an existing column and the pattern only contains the symbols |, -, = (and [space], [LF]). Also, two adjacent columns cannot both contain dashes (in the same line). The dimensions of the pattern are unknown (min 1x1). Clarifications #2 There are two invalid patterns: |-|-| and |=|=| which create ambiguity. The given input string will never contain those. The input variables are the same for all; a numeric value and a string representing the pattern. Entrants must produce a function. Test case Given pattern: "|-| |=|-|=|LF| |-| | |-|LF|=| |-| | |LF| | |-|=|-|" |-| |=|-|=| | |-| | |-| |=| |-| | | | | |-|=|-| Given value : Expected result 1 : 6 2 : 1 3 : 3 4 : 6 5 : 5 6 : 2

  • 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"

  • Performing multiple fetches in Core Data within the same view

    - by yesimarobot
    I have my CD store setup and everything is working. Once my initial fetch is performed, I need to perform several fetches based on calculations using the data from my first fetch. The examples provided from Apple are great, and helped me get everything going but I'm struggling with executing successive fetches. Any suggestions, or tutorial links are appreciated. Table View loads data from CD store. When a user taps a row it pushes a detail view The detail view loads details from CD. [THE ABOVE STEPS ARE ALL WORKING] I perform several calculations on the data fetched in the detail view. I need to then perform several other fetches based on the results of my calculations.

  • Dynamically add annotation to an existing class

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.

  • 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?

  • 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?

  • 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.
