  • Linq and Lamba Expressions - while walking a selected list perform an action

    - by Prescott
    Hey, I'm very new to linq and lamba expressions. I'm trying to walk a collection, and when I find an item that meets some criteria I'd like to add that to another separate collection. My linq to walk the collection looks like this (this works fine): From i as MyCustomItem In MyCustomItemCollection Where i.Type = "SomeType" Select i I need each of the select items to then be added to a ListItemCollection, I know I can assign that linq query to a variable, and then do a for each loop adding a new ListItem to the collection, but I'm trying o find a way to add each item to the new ListItemcollection while walking, not a second loop. Thanks ~P

  • Should I obscure primary key values?

    - by Scott
    I'm building a web application where the front end is a highly-specialized search engine. Searching is handled at the main URL, and the user is passed off to a sub-directory when they click on a search result for a more detailed display. This hand-off is being done as a GET request with the primary key being passed in the query string. I seem to recall reading somewhere that exposing primary keys to the user was not a good idea, so I decided to implement reversible encryption. I'm starting to wonder if I'm just being paranoid. The reversible encryption (base64) is probably easily broken by anybody who cares to try, makes the URLs very ugly, and also longer than they otherwise would be. Should I just drop the encryption and send my primary keys in the clear?

  • How do I set the Execute Permissions for an IIS6 website with Powershell using WMI?

    - by DarkwingDuck
    In inetmgr you can set the property I desire by going to Home Directory - Application Settings - Execute Permissions - and setting the drop down to 'Scripts Only'. I'm trying to replicate this behavior in Powershell. The Target OS is Windows Server 2003 running IIS6. Currently I have this simple code to get the site: $Site = get-wmiobject -Namespace root\MicrosoftIISv2 -query ('select * from IISWebServerSetting where ServerComment="mySite"') There are lots of properties it might be but nothing really leaps out. I've tried changing the setting in inetmgr and dumping the properties out before and after, but I see no differences (it could be a child property though). Any ideas? Thanks in advance.

  • remove multiple trailing slashes mod_rewrite

    I know this question was asked a number of times on this site alone, but browsing through the relevant posts I couldn't find a solution. Trying to remove multiple trailing slashes after domain.

  • SQL Having Clause

    - by Wally
    I'm trying to get a stored procedure to work using the following syntax: select count(sl.Item_Number) as NumOccurrences from spv3SalesDocument as sd left outer join spv3saleslineitem as sl on sd.Sales_Doc_Type = sl.Sales_Doc_Type and sd.Sales_Doc_Num = sl.Sales_Doc_Num where sd.Sales_Doc_Type='ORDER' and sd.Sales_Doc_Num='OREQP0000170' and sl.Item_Number = 'MCN-USF' group by sl.Item_Number having count (distinct sl.Item_Number) = 0 In this particular case when the criteria is not met the query returns no records and the 'count' is just blank. I need a 0 returned so that I can apply a condition instead of just nothing. I'm guessing it is a fairly simple fix but beyond my simple brain capacity. Any help is greatly appreciated. Wally

  • Does performance even matter anymore? [closed]

    - by Jeff Dahmer
    The performance differences between C/C++ and C# are astounding. An ASP.NET page loads in 1/8 the time that a PHP script does haha.... WPF, aka " The Future ", (you know it will be, all the companies are gonna want cool looking desktop apps, don't kid yourself.) And it has huge performance hits just to start up. We've let Microsoft make us as developers lazy! Why do I hate this, it's such a good thing? Are we at a point in time where the majority of computers can handle this kinda crap? I remember when performance used to matter. Anyways, I'm writing a .NET library and ever since I found out LINQ is slower than traditional delegates which is slower than the normal procedural code... well it's a guilty evil I feel for every LINQ query I write, because they are so beautiful. Am I just too much of a performance stickler? Or just too big of a nerd?

  • Ruby on Rails ActiveRecord: eager loading issue with foreign and primary key

    - by Krishnaswamy Subramanian
    The eager loading on Ruby on Rails is not working properly for the following scenario. First we had a model called marks which has the following fields id, student, subject, mark the student is a string column which has the active directory login value, later on for reporting functionality we introduce another table called user which has the following fields id, ad_name, full_name Now on the Mark model, we have added the belongs to class belongs_to :student_details, :class_name = "User", :foreign_key = "student", :primary_key = "ad_name" and when loading using the ActiveRecord's find method we are passing in the include conditon for eager loading Marks.find(:all, :include = :reserved_user) but when the find is executed, for each and every mark a student select query executed. Is this a known bug in ROR? or am i missing something?

  • Joining two tables using a count

    I have two tables as defined below: EMAILS ID SUBJECT BODY 1 Test1 blah blah 2 Test2 blah blah blah 3 Test3 more blah ATTACHMENTS ID EMAIL_ID ATTACHMENT NAME 1 2 TEST.DOC 2 2 TEST.XLS I'm trying to perform a select to get back all of the emails and a count of how many attachments (if any) for each row in the EMAILS table -- preferably in a single query where the results would resemble something like: EMAIL_ID SUBJECT NUM_ATTACHMENTS BODY 1 Test1 0 blah blah 2 Test2 2 blah blah blah 3 Test3 0 more blah I've tried everything but the "right way" and if anyone has a few minutes to help me create the right SQL to build this, I'd greatly appreciate it. Thanks.

  • Problem referencing querystring using fb:req-choice

    - by vondip
    Hi all, I am building a small facebook application. I am using asp.net and currently working with the fb:req-choice control (tied along with fb:request-form and fb:multi-friend-selector). Problem is, that when I specify the redirect url for when the user clicks my invitation, instead of getting what I specified: http://apps.facebook.com/myApp/forum.aspx?tId=1&ref=app&code=2.74rRNejG7tpAOqgDCNf8qA__.3600.1275202400-106570384737670%7CPi8JpoHDW3xGuq2lxdZl1d4CLUU. This is what I am getting: http://apps.facebook.com/myApp/forum.aspx?tId&code=2.74rRNejG7tpAOqgDCNf8qA__.3600.1275202400-106570384737670%7CPi8JpoHDW3xGuq2lxdZl1d4CLUU. as you can see my query string isn't getting parsed. Instead, only the first parameter is written, why is that? How can I get this right?

  • Custom Lucene Sharding with Hibernate Search

    - by Timo Westkämper
    Has anyone experience with custom Lucene sharding / paritioning using Hibernate Search? The documentation of Hibernate Search says the following about Lucene Sharding : In some cases, it is necessary to split (shard) the indexing data of a given entity type into several Lucene indexes. This solution is not recommended unless there is a pressing need because by default, searches will be slower as all shards have to be opened for a single search. In other words don't do it until you have problems :) Has anyone implemented sharding in such a way for Hibernate Search that also queries can be target to one of the shards? In our case we have Lucene queries that should target only one shard per query.

  • Select count() max() Date

    I have a table with shifts history along with emp ids. I'm using this query to retrieve a list of employees and their total shifts by specifying the range to count from: SELECT ope_id, count(ope_id) FROM operator_shift WHERE ope_shift_date >=to_date( '01-MAR-10','dd-mon-yy') and ope_shift_date <= to_date('31-MAR-10','dd-mon-yy') GROUP BY OPE_ID which gives OPE_ID COUNT(OPE_ID) 1 14 2 7 3 6 4 6 5 2 6 5 7 2 8 1 9 2 10 4 10 rows selected. How do I choose the employee with the highest number of shifts under the specified range date?

  • Localization as an afterthought-- screwed?

    - by David
    So I signed on with a startup web development company as a subcontractor. They are putting together a large, complex user/product management system for a company that needs to support multiple levels of hierarchial localization. I signed a 3 month contract, and upon looking at their code, wish I hadn't. They opted to write their own MVC framework (I guess the client company didn't want to use a prewritten one) and it's extremely poorly written. There's SQL scattered throughout almost every model view and controller (and there's no parameter-based find methods, it's all SQL) and they haven't even THOUGHT about localization yet-- something that will have an affect on nearly EVERY query. The due date is 4 months away, and I honestly think we'd make good progress by scrapping the whole thing and going with CakePHP. Have any of you been in a similar situation, and what did you do? PS: This is written in PHP/MySQL.

  • HTTP Content-type header for cached files

    - by Brian
    Hello, Using Apache with mod_rewrite, when I load a .css or .js file and view the HTTP headers, the Content-type is only set correctly the first time I load it - subsequent refreshes are missing Content-type altogether and it's creating some problems for me. I can get around this by appending a random query string value to the end of each filename, eg. http://www.site.com/script.js?12345 However, I don't want to have to do that, since caching is good and all I want is for the Content-type to be present. I've tried using a RewriteRule to force the type but still didn't solve the problem. Any ideas? Thanks, Brian

  • Some special characters defined in "ISO-8859-1" can't be shown when encoding with "UTF-8"

    - by Mike.Huang
    I need to get a string from URL request of brower, and then create a text image by requested text. I know the default encoding of the Java net transmission is "ISO-8859-1", it can works normally with all characters what defined in "ISO-8859-1". But when I request a multi-byte Unicode character (e.g. chinese or something like ¤?), then I need to decode it by "UTF-8" from "ISO-8859-1". My codes like: String reslut = new String(requestString.getBytes("ISO-8859-1"), "UTF-8"); Everything is fine, but I found some characters in ISO-8859-1 are not been shown now, which characters are 0x80 - 0xFF(defined in" ISO-8859-1"), i.e. the characters after 0x80 (in "ISO-8859-1") not been shown when converted to "UTF-8" from "ISO-8859-1". Any other method can solve this query?

  • I need to know what link is clicked, how do i get these variables with cherrypy?

    Lets say I display 3 links, I want to accomplish 2 things, know which link is clicked, and record this choice in a list/pickle or txt file but also capture this variable in cherrypy so I can perform another action. How do I do this? Its been suggested that I use a query string which makes sense but I can't get the querystring variable to cherrypy to use for further actions. So would anyone have a simple code of cherrypy with lets say 2 pages and have one page display 2 links with a querystring in each and the second page able to get that value?

  • How do you get average of sums in SQL (multi-level aggregation)?

    - by paxdiablo
    I have a simplified table xx as follows: rdate date rtime time rid integer rsub integer rval integer primary key on (rdate,rtime,rid,rsub) and I want to get the average (across all times) of the sums (across all ids) of the values. By way of a sample table, I have (with consecutive identical values blanked out for readability): rdate rtime rid rsub rval ------------------------------------- 2010-01-01 00.00.00 1 1 10 2 20 2 1 30 2 40 01.00.00 1 1 50 2 60 2 1 70 2 80 02.00.00 1 1 90 2 100 2010-01-02 00.00.00 1 1 999 I can get the sums I want with: select rdate,rtime,rid, sum(rval) as rsum from xx where rdate = '2010-06-01' group by rdate,rtime,rid which gives me: rdate rtime rid rsum ------------------------------- 2010-01-01 00.00.00 1 30 (10+20) 2 70 (30+40) 01.00.00 1 110 (50+60) 2 150 (70+80) 02.00.00 1 190 (90+100) as expected. Now what I want is the query that will also average those values across the time dimension, giving me: rdate rtime ravgsum ---------------------------- 2010-01-01 00.00.00 50 ((30+70)/2) 01.00.00 130 ((110+150)/2) 02.00.00 190 ((190)/1) I'm using DB2 for z/OS but I'd prefer standard SQL if possible.
