  • USB device Set Attribute in C#

    - by p19lord
    I have this bit of code: DriveInfo[] myDrives = DriveInfo.GetDrives(); foreach (DriveInfo myDrive in myDrives) { if (myDrive.DriveType == DriveType.Removable) { string path = Convert.ToString(myDrive.RootDirectory); DirectoryInfo mydir = new DirectoryInfo(path); String[] dirs = new string[] {Convert.ToString(mydir.GetDirectories())}; String[] files = new string[] {Convert.ToString(mydir.GetFiles())}; foreach (var file in files) { File.SetAttributes(file, ~FileAttributes.Hidden); File.SetAttributes(file, ~FileAttributes.ReadOnly); } foreach (var dir in dirs) { File.SetAttributes(dir, ~FileAttributes.Hidden); File.SetAttributes(dir, ~FileAttributes.ReadOnly); } } } I have a problem. It is trying the code for Floppy Disk drive first which and because no Floppy disk in it, it threw the error The device is not ready. How can I prevent that?

  • Efficient mapping for a particular finite integer set

    - by R..
    I'm looking for a small, fast (in both directions) bijective mapping between the following list of integers and a subset of the range 0-127: 0x200C, 0x200D, 0x200E, 0x200F, 0x2013, 0x2014, 0x2015, 0x2017, 0x2018, 0x2019, 0x201A, 0x201C, 0x201D, 0x201E, 0x2020, 0x2021, 0x2022, 0x2026, 0x2030, 0x2039, 0x203A, 0x20AA, 0x20AB, 0x20AC, 0x20AF, 0x2116, 0x2122 One obvious solution is: y = x>>2 & 0x40 | x & 0x3f; x = 0x2000 | y<<2 & 0x100 | y & 0x3f; Edit: I was missing some of the values, particularly 0x20Ax, which don't work with the above. Another obvious solution is a lookup table, but without making it unnecessarily large, a lookup table would require some bit rearrangement anyway and I suspect the whole task can be better accomplished with simple bit rearrangement. For the curious, those magic numbers are the only "large" Unicode codepoints that appear in legacy ISO-8859 and Windows codepages.

  • C++ STL list vs set

    - by mokaschitta
    Hi, what of those two is faster for random insertions and deletions? I guess list, having the values as the keys as it is with sets seems to be attractive too though. Is performance similar for iterating over the whole container? Thanks!

    I'm wondering if it's possible to use a wildcard to select multiple cookies. I'm using jquery to save various scroll position and would like to clear them out in one go. At the moment I clear them out individually as below function clearScroll(elementID) { if ($.cookie) { $.cookie(elementID + '_scrollpos', 0); } } What I'd like is a clear all something like below. function clearAllScroll() { if ($.cookie) { $cookie([name$='_scrollpos'],0); } } Is this possible?

  • Set AUTO_INCREMENT value programmatically

    - by Tim
    So this works... ALTER TABLE variation AUTO_INCREMENT = 10; But I want to do this; ALTER TABLE variation AUTO_INCREMENT = (SELECT MAX(id)+1 FROM old_db.varaition); but that doesnt work, and neither does; SELECT MAX(id)+1 INTO @old_auto_inc FROM old_db.variation ALTER TABLE variation AUTO_INCREMENT = @old_auto_inc; So does anyone know how to do this? ( I'm trying to ensure that AUTO_INCREMENT keys dont collide between an old and a new site and need to do this automatically. So I can just run a script when the new db goes live )

  • Is this data set in third normal form?

    - by user2980802
    UNF: (Customer-name, Customer-id, Customer-address, (Unit-price, Order-id, Quantity, Product-id, Delivery-date) (Supplier-name, Supplier-id, Supplier-Address) 3NF: CUSTOMER (Customer-id, Order-id, Customer-name, Customer-address) ORDER (Order-id, Customer-id) ORDER/PRODUCT (Order-id, Quantity, Product-id) PRODUCT (Order-id, Product-id, Delivery-date, Supplier-id, Unit-price,) SUPPLIER (Supplier-name, Supplier-id, Supplier-Address, Product-id) Basically, the UNF is the un-normalised form. The information should have EXACTLY five tables, it's a hint we were given. The tables listed are the definite table names. We were told to make assumptions based on this information: Customer Invoice is generated from customer orders (Order & Order/Product entities) Supplier Order is generated for products that are low in stock (Product entity) Assumptions A customer can place many orders but an order is placed by only one customer An order can be for many products and a product can be ordered many times A product is supplied by only one supplier, a supplier may supply many products This is one of my modules in university and my lecturer is all but useful, I'm really struggling so any help is really appreciated.

  • $_SERVER['HTTP_HOST'] not set

    - by yes123
    Hi guys, I am getting lot of traffic to my php pages but without the variable $_SERVER['HTTP_HOST'] setted. This traffic is like 1 hit per second. I don't know what it could be, but for reducing server load i am doing this at the top of every php pages: if (!isset($_SERVER['HTTP_HOST'])) exit; Do u know what could cause this? Is it safe to exit whenever http_host is not setted? Can a normal user visit my pages without setting http_host? PHP version: 5.2.0-8, Apache: 2.2.3 Thanks

  • How to predict result set row count?

    - by Saurabh Kumar
    I have an application where I create a big SQL query dynamically for SQL server 2008. This query is based on various search criteria which the user might give such as search by lastname, firstname, ssn etc. The requirement is that if the user gives a condition due to which the formed query might return a lot of rows(configurable for max N rows), then the application must send back a message instead to the user saying that he needs to refine his search query as the existing query will return too many rows. I would not want to bring back say, 5000 rows to the client and then discard that data just to show the user an error. What is an efficient way to tackle this issue?

  • Environment.GetFolderPath(...CommonApplicationData) is still returning c:\Docs&Set on Vista

    - by blak3r
    As i understand it, you're supposed to use Environment.GetFolderPath method so you have OS independent code... WinXP uses C:\Docs and Settings\ Vista uses C:\ProgramData and c:\Users I'm using the code below on a vista computer and it's returning a c:\documents and settings directory instead of c:\ProgramData like it should... Any ideas? string commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData); try { File.CreateText( Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "\\mycompany\\uid"); log.Debug("Created file successfully"); } catch (Exception ex) { log.Error("Unable to create the uid file: ", ex); } EDIT: I was mistaken... See my answer below. Please vote to close this post as it's no longer relevent.

  • Windows 8 Set User Account Image

    - by Nexion
    I'm trying to write a small CONSOLE (not metro style) app to quickly change the user account image of the current user to a select image for a setup scrip that I'm running on a bunch of laptops. They're all Windows 8 and (since it hasn't been out terribly long) I can't find a ton of info on it. I did manage to figure out that you need to use the Windows.System.UserProfile object to do so, but I can't find any documentation on how to do so in a console app. Thoughts? Suggestions?

  • How to dynamically set div size?

    I have a div container with a text that has been previously typed in by the user. I would like to adjust the size of the div to this text. I cannot have fixed size because I dont know the length of the text. If there is no size specified div takes the width of entire window. This cause some problems for me because I am using JQuery draggable plugin and the scrollbars appear immediately when the div is dragged. Any advice on that?

  • How to return result set based on other rows

    - by understack
    I've 2 tables - packages and items. Items table contains all items belonging to the packages along with location information. Like this: Packages table id, name, type(enum{general,special}) 1, name1, general 2, name2, special Items table id, package_id, location 1, 1, America 2, 1, Africa 3, 1, Europe 4, 2, Europe Question: I want to find all 'special' packages belonging to a location and if no special package is found then it should return 'general' packages belonging to same location. So, for 'Europe' : package 2 should be returned since it is special package (Though package 1 also belongs to Europe but not required since its a general package) for 'America' : package 1 should be returned since there are no special packages
