• Can a user be a member of multiple Organization Units (OU) in Active Directory ?

  - by Stormshadow

  Can a user be a member of multiple Organization Units (OU) in Active Directory ? Also, is there a standard format mentioned by Microsoft on how an OU should be created and what its attributes are ? I found this in Wikipedia "However, Organizational Units are just an abstraction for the administrator, and do not function as true containers; the underlying domain operates as if objects were all created in a simple flat-file structure, without any OUs. It is not possible for example to create two user accounts with an identical username in two separate OUs, such as "fred.staff-ou.domain" and "fred.student-ou.domain"."

• Object to Network serialization - with an existing protocol

  - by cpf

  I'm writing a client for a server program written in C++. As is not unusual, all the networking protocol is in a format where packets can be easily memcopied into/out of a C++ structure (1 byte packet code, then different arrangements per packet type). I could do the same thing in C#, but is there an easier way, especially considering lots of the data is fixed-length char arrays that I want to play with as strings? Or should I just suck it up and convert types as needed? I've looked at using the ISerializable interface, but it doesnt look as low level as is required.

• Read multiple strings from a file C++

  - by user69514

  Hi I need to read different values stored in a file one by one. So I was thinking I can use ifstream to open the file, but since the file is set up in such a way that a line might contain three numbers, and the other line one number or two numbers I'm not sure how to read each number one by one. I was thinking of using stringstream but I'm not sure if that would work. The file is a format like this. 52500.00 64029.50 56000.00 65500.00 53780.00 77300.00 44000.50 80100.20 90000.00 41000.00 60500.50 72000.00 I need to read each number and store it in a vector. What is the best way to accomplish this? Reading one number at a time even though each line contains a different amount of numbers?

• PHP, manipulating images and thumbnails?

  - by learner.php

  I am using php and mysql. I allow my registered users to upload photos, the photos are store in filesystem format, then I will keep the original/max size of : width: 1600px and heigh: 1200px. In the user profile page, I would like to display the image, it maybe one of the 5 types of thumnails: 500x500, 300x300, 200x200, 100x100 or 50x50. What is the best way to create the thumbnails, here are my current solutions: I am thinking of create 1 thumbnail, then from that thumbnail, i will resize in [img src="" width="XX"] tag, alternatively, store the different thumbnails size in database, then get and display it Create 5 thumbnails for each photos? (I am afraid this is a bad way) Whats the best practices?

• MySQL Query, limit output display according/only to associated ID!

  - by Jess

  So here's my situation. I have a books table and authors table. An author can have many books... In my authors page view, the user (logged in) can click an author in a tabled row and be directed to a page displaying the author's books (collected like this URI format: viewauthorbooks.php?author_id=23), very straight forward... However, in my query, I need to display the books for the author only, and not all books stored in the books table (as i currently have!) As I am a complete novice, I used the most simple query of: SELECT * FROM tasks_tb :)....this returns the books for me, but returns every single value (book) in the database, and not ones associated with the selected author. And when I click a different author the same books are displayed for them...I think everyone gets what I'm trying to achieve, I just don't know how to perform the query. I'm guessing that I need to start using more advanced query clauses like INNER JOIN etc. Anyone care to help me out :)

But the problem is that image is too big. Now my problem is how to shrink image or I want to see the image in page in normal format. Now how can I do it ?

• Java class Class<T> and static method Class.forName() drive me crazy.

  - by matt

  Hi, this code doesn't compile. i'm wandering what i am doing wrong: private static Importable getRightInstance(String s) throws Exception { Class<Importable> c = Class.forName(s); Importable i = c.newInstance(); return i; } where Importable is an interface and the string s is the name of an implementing class. The compiler says: ./Importer.java:33: incompatible types found : java.lang.Class<capture#964 of ?> required: java.lang.Class<Importable> Class<Importable> c = Class.forName(format(s)); thanks for any help!

• How can I possibly sort this in JavaScript?

  - by orokusaki

  I've been pounding my head on the wall trying to figure out how to sort this in JavaScript (I have to work with it in this format unfortunately). I need to sort it based on Small, Medium, Large, XL, XXL (Small ranking the highest) in each variationValues size field. The problem is that I need to sort the variationCosts and variationInventories at the same time to match the new order (since each value in order corresponds to the values in the other fields :( Input I have to work with var m = { variationNames: ["Length", "Size" ], variationValues: [ ["26.5\"", "XXL"], ["25\"", "Large"], ["25\"", "Medium"], ["25\"", "Small"], ["25\"", "XL"], ["25\"", "XXL"], ["26.5\"", "Large"], ["26.5\"", "Small"], ["26.5\"", "XL"] ], variationCosts: [ 20.00, 20.00, 20.00, 20.00, 20.00, 20.00, 20.00, 20.00, 20.00 ], variationInventories: [ 10, 60, 51, 10, 15, 10, 60, 10, 15 ], parentCost: 20.00 }; Desired output var m = { variationNames: ["Length", "Size" ], variationValues: [ ["25\"", "Small"], ["26.5\"", "Small"], ["25\"", "Medium"], ["25\"", "Large"], ["26.5\"", "Large"], ["25\"", "XL"], ["26.5\"", "XL"] ["25\"", "XXL"], ["26.5\"", "XXL"], ], variationCosts: [ 20.00, 20.00, 20.00, 20.00, 20.00, 20.00, 20.00, 20.00, 20.00 ], variationInventories: [ 10, 10, 51, 60, 15, 15, 15, 10, 10 ], parentCost: 20.00 };

• Getting fields of a class through reflection

  - by Water Cooler v2

  I've done it a gazillion times in the past and successfully so. This time, I'm suffering from lapses of amnesia. So, I am just trying to get the fields on an object. It is an embarrassingly simple and stupid piece of code that I am writing in a test solution before I do something really useful in production code. Strangely, the GetFieldsOf method reports a zero length array on the "Amazing" class. Help. class Amazing { private NameValueCollection _nvc; protected NameValueCollection _myDict; } private static FieldInfo[] GetFieldsOf(string className, string nameSpace = "SomeReflection") { Type t; return (t = Assembly.GetExecutingAssembly().GetType( string.Format("{0}.{1}", nameSpace, className) )) == null ? null : t.GetFields(); }

• Unwanted SQLite inserted in \bin

  - by wilk

  I am using Visual Studio 2010 and using web deployment to promote the .Net MVC site to specific environments. I installed Elmah, and it worked great on my DEV environment, but when I pushed TEST, I got exceptions because SQLite was not a good format. I am not using SQLite in Elmah or otherwise that I know of. I have removed all visible refernces to SQLite, and I have removed the .dll from all configuration bin directories. But it still gets inserted with each build. I realize the exception problem is that SQLite cannot be built for CPU Any, and my environments vary from x86 to x64. But I would prefer SQLite to not even be present. I have since uninstalled Elmah, and SQLite is still inserted into the \bin directory. I have now re-installed Elmah, and I manually delete the SQLite.dll from \bin after each build. How can I determine what is causing SQLite to be inserted into my \bin after each build?

• What is the point of heightmaps?

  - by Jake Petroules

  I've been pondering this question awhile now... many 3d engines support advanced terrain rendering using quadtrees, LOD... all the features you expect. But every engine I've seen loads height data from heightmaps... grayscale bitmaps. I just can't understand how this is useful - each point in a heightmap can have one of 256 values. But what if you wanted to model Mt. Everest? with detail of 1 meter, or even greater? That's far outside the range of 256. Of course I understand that you can implement your own terrain format to achieve this, but I just can't see why heightmaps are so widely used despite their great limitations.

• how to generate large image in compact framework

  - by Buthrakaur

  I need to generate large images (A4 image at 200 DPI, PNG format would be fine) in my compact framework application. This is impossible to do in standard way due to memory limitations (such big image will throw OOMException). Is there any library which offers file-backed stream image generation? Or I could generate many smaller stripes of images (each stripe representing a row of the large image) using standard Bitmap approach, but I need to merge them together afterwards - is there any method how to merge many smaller images into one large without having to instantiate large Bitmap instance (which would again cause OOM)?

• msbuild conversion tool to VS2010

I'd like to run the conversion tool for getting VS2010 project file. What's the tool for it?

• Screen recorder for tracking back your steps while debugging?

  - by hstoerr

  I am wondering whether there is a screen recorder that is usable for checking what exactly you did a couple of minutes ago while debugging, or just checking what value for a variable was displayed the last time you hit that breakpoint etc. (Of course this latter question would be something terrific for an IDE to implement, but I've never seen something like that so far. :-) For this you would need a screen recorder that could record all day and preferably automatically delete the recording the recording that is, say, older than an hour. Probably the recording format should be something that is good for screen recording instead of natural scenes. Do you know a screen recorder like that or at least one that comes close?

• Chrome/Webkit audio tag bug?

  I'm trying to get HTML5's audio tag to work in Chrome. The following code works flawlessly in Firefox, any ideas why it isn't working in Webkit? <html> <head> <script type="text/javascript"> function init(){ audio = new Audio("chat.ogg"); audio.play(); } </script> </head> <body onload="init()"> </body> I should also note that I tried this with an mp3 as well. Regardless of what format, whenever .play() is called on audio, Chrome responds with "undefined".

• How can I plot a time series graph with Perl?

  - by Jazz

  I have some data from a database (SQLite), mapping a value (an integer) to a date. A date is a string with this format: YYYY-MM-DD hh:mm. The dates are not uniformly distributed. I want do draw a line graph with the dates on X and the values on Y. What is the easiest way to do this with Perl? I tried DBIx::Chart but I could not make it recognize my dates. I also tried GD::Graph, but as the documentation says: GD::Graph does not support numerical x axis the way it should. Data for X axes should be equally spaced

• free RSS feed caching

  - by cherouvim

  Hello I've got an application which serves an rss feed of headlines and I need to provide this rss feed to other consumers. I don't want to provide the rss directly from my server though, due to limited server resources, so I need to proxy (cache) it through some service which will handle the load. Assuming the rss feed URL of my application is http://example.com/rss I initially provided my consumers with the url http://ajax.googleapis.com/ajax/services/feed/load?v=1.0&q=http%3A%2F%2Fexample.com%2Frss which solved my server load problem but introduced a liveness problem. The headlines are minutes to hours late from the actual feed (haven't exactly measured how much late). I've also tried distributing through feedburner so the url became something like http://feeds.feedburner.com/example123?format=xml but the liveness problem still exists. Is there a public and free solution for this problem? Anything below 5 minutes of liveness delay would be totally acceptable. thanks

• Calling a static Func from a static class using reflection

  - by ChrisO

  Given the static class: public static class Converters { public static Func<Int64, string> Gold = c => String.Format("{0}g {1}s {2}c", c/10000, c/100%100, c%100); } I am receiving the Func name from a database as a string (regEx.Converter). How can I invoke the Gold Func using reflection? Here is what I have so far: var converter = typeof(Converters).GetMember(regEx.Converter); if (converter.Count() != 0) { //throw new ConverterNotFoundException; } matchedValue = converter.Invoke(null, new object[]{matchedValue}) as string;
