  • return from a linq where statement

    - by Vaccano
    I have the following link function MyLinqToSQLTable.Where(x => x.objectID == paramObjectID).ToList(); I most of the time you can change a linq call to be several lines by adding curly brackets around the method body. Like this: MyLinqToSQLTable.Where(x => { x.objectID == paramObjectID; }).ToList(); Problem is the implied return that was there when I just did a Boolean compare is now not done. Return (x.objectID == paramObjectID); is not accepted either. How do do this? can I do this? NOTE: I know that I can add another where clause if needed. But I would still like to know the answer to this.

  • JDBC Realm: GlassFish v2.1 = OK; GlassFish v3 = fail with invaliduserreason

    - by Vik Gamov
    In my J2EE 5 application I have a JDBC Realm based security with Form method. Encrypt method is MD5 as default. The database is PostgreSQL 8.4 installed locally (or 8.3 available via lan). My app used to work finely on GlassFish v2.1 server with PostgreSQL 8.3, but now I need to deploy it on GlassFish v3. I am absolutely sure I have done all the same config on GFv3 like creating Connection Pool (which pings with no problem), JDBC Resource and JDBC Realm. But on GFv3 I get login exception with "invaliduserreason" while the database schema is just created from the working database script. I have checked the data and entered login/password thousand times and it seems that data is all right. So where can I find the reason of unworking security? Please, advice. NetBeans 6.8 Thanks.

  • Passing multiple codeblocks as arguments

    - by doctororange
    I have a method which takes a code block. def opportunity @opportunities += 1 if yield @performances +=1 end end and I call it like this: opportunity { @some_array.empty? } But how do I pass it more than one code block so that I could use yield twice, something like this: def opportunity if yield_1 @opportunities += 1 end if yield_2 @performances +=1 end end and: opportunity {@some_other_array.empty?} { @some_array.empty? } I am aware that this example could be done without yield, but it's just to illustrate. Thanks.

  • SharePoint 2010 - Can two or more people edit a file at the same time?

    - by Tobias Funke
    I have a SharePoint 2010 site with a document library for storing Excel files. If someone is editing an Excel file (using stand-alone Excel, not Excel services), everyone else will be forced to open the file read-only until the first person is done editing. Is there a way around this? What I want is to allow two or more people to be able to edit the file at the same time. Also, I don't want people to overwrite each other. Instead, I'd like SharePoint to merge their changes. Is this possible in SharePoint 2010?

  • SQL COUNT of COUNT

    - by cryptic-star
    I have some data I am querying. The table is composed of two columns - a unique ID, and a value. I would like to count the number of times each unique value appears (which can easily be done with a COUNT and GROUP BY), but I then want to be able to count that. So, I would like to see how many items appear twice, three times, etc. So for the following data (ID, val)... 1, 2 2, 2 3, 1 4, 2 5, 1 6, 7 7, 1 The intermediate step would be (val, count)... 1, 3 2, 3 7, 1 And I would like to have(count_from_above, new_count)... 3, 2 -- since three appears twice in the previous table 1, 1 -- since one appears once in the previous table Is there any query which can do that? If it helps, I'm working with Postgres. Thanks!

  • JiBX binding DTD schema in Eclipse

    - by Trick
    I have warnings in binding xml files: No grammar constraints (DTD or XML schema) detected for the document. I have done as is written in the answer here: http://stackoverflow.com/questions/982263/jibx-how-do-i-keep-using-interfaces-in-my-code (answer which is not accepted). But now I have an error in binding xml file: Referenced file contains errors (file:/C:/Amplio/LiveCliq/Work/core/src/main/resources/config/rest/ mappings/binding.dtd). For more information, right click on the message in the Problems View and select "Show Details..." And the details are: The markup in the document preceding the root element must be well-formed. line 20 I am not familiar with DTD schemas, so I don't know what is the problem. Did anybody found the solution? And - I do not want to turn off validation in XML files, I would like to have this in binding files (mainly for code assist and validation).

  • Using ELMAH and URLRewritingNet Together

    - by Chris Laythorpe
    I have ELMAH setup on my production server and it has done a fantastic job of letting me know about any niggles - as well as any creative SQL injection! I've decided to introduce URl Rewriting and went for http://www.urlrewriting.net/ in the end. It was nice and easy to setup and it's doing exactly what I want with the customer-facing site. The problem is ELMAH. Because I've set the urlrewritingnet node in my config like so: <urlrewritingnet rewriteOnlyVirtualUrls="true" contextItemsPrefix="QueryString" defaultPage = "default.aspx" defaultProvider="RegEx" xmlns="http://www.urlrewriting.net/schemas/config/2006/07" > ...ELMAH likes to do this to it's axd links; http://www.mydomain.com/elmah.axd/stylesheet/default.aspx Does anyone have any idea how to either a) stop the re-writer following the .axd; or b) add rules to the re-writer to get ELMAH to work Any ideas? I'm happy to hack about with the httpHandlers...

  • iPhone: Group by month - Core Data

    - by Shaun
    Hi I store dates in a core data entity attribute, I then display the date in the table cells. I want to group all the cells according to months and only display the relevant dates in the correct sections. I'm using sectionNameKeyPath of the NSFetchedResultsController, but I need to only use the month in the date to group. How can I achieve this? Would I need to create a new attribute and store just the month as a string or can I use NSPredicate? Please can anyone let me know if they have done this or give me some examples. Thanks

  • Is there any er diagram tool in Windows that I can use to connect to a MySQL 4.1 database in Unix?

    - by melaos
    I have a few test databases in some Unix SUSE 8 servers and initially the plan was to find some tools which can directly create the ERD straight from the server until someone told me that I can find tools to connect from the Windows PC straight to the Unix MySQL database. So I saw MySQL query analyzer which can do this but unfortunately there are no options to create an ERD. So are there any tools, preferably open source or free which can do this? I've done some basic googling but didn't know what is the exact terms to use to search for this and have so far found nothing useful yet. Updates: I just found out that the latest version of workbench doesn't work MySQL 4.1 Enterprise Edition which is the version that I have! And I try to use fabFORCE DBDesigner but I can't even connect at all using that one :( What can work for this version of MySQL?

  • iPhone - Is it ok to override UITableViewCell setSelected:animated

    - by Brian
    I am drawing custom UITableViewCells. My cells are opaque and are completely drawn in the drawRect of the cell to help with performance. I want to handle the look of a selected cell myself. If I don't, then the contents of my cell is covered up by the selectedBackgroundView that is added. Is it common or acceptable to override the setSelected:animated method of my cell so this is done properly. I guess if I did that, then I would not call the super's setSelected method since I would be handling how the cell will show that its selected. I would also have to set the selected property of the cell. Any help would be great. Thanks.

  • How can I make two "user" editable areas in Wordpress?

    - by thatryan
    Hi all, is there a way to have two posting areas in Wordpress, for clients who can not go into any HTML? Basically the template has 3 columns. One is vertical nav, thats no prob. Second is like a "sidebar" but where the main post will go, a skinny column. Third is large, "main area" size, but will also be user editable content. Does that make sense? Has anyone done something like this before? Thank you.

  • Somebody is storing credit card data - how are they doing it?

    - by pygorex1
    Storing credit card information securely and legally is very difficult and should not be attempted. I have no intention of storing credit card data but I'm dying to figure out the following: My credit card info is being stored on a server some where in he tworld. This data is (hopefully) not being stored on a merchant's server, but at some point it needs to be stored to verify and charge the account identified by merchant submitted data. My question is this: if you were tasked with storing credit card data what encryption strategy would you use to secure the data on-disk? From what I can tell submitted credit card info is being checked more or less in real time. I doubt that any encryption key used to secure the data is being entered manually, so decryption is being done on the fly, which implies that the keys themselves are being stored on-disk. How would you secure your data and your keys in an automated system like this?

  • Using .htaccess to force either HTTP or HTTPS

    - by ILMV
    I have already got this code to force these URLs to HTTPS: RewriteCond %{HTTPS} off RewriteCond %{REQUEST_URI} ^/my/?.*$ RewriteCond %{REQUEST_URI} !^/my/basket/add/$ RewriteCond %{REQUEST_URI} ^/login/?.*$ RewriteCond %{REQUEST_URI} ^/logout/?.*$ RewriteCond %{REQUEST_URI} ^/register/?.*$ RewriteCond %{REQUEST_URI} ^/newsletter/?.*$ RewriteCond %{REQUEST_URI} ^/reset-password/?.*$ RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L] And this works really well, but what I want to do is force any URL that does not comply with the above conditions to HTTP. Any thoughts on how I could do this? It has to be done using .htaccess, I have been achieving it by using our PHP framework, but this has been messing our Google crawl. Cheers!

  • Caching Solutions

    - by dave
    Has anyone done a thorough comparison of AppFabric and NCache or AppFabric and ScaleOut? We are currently looking to implement either AppFabric, NCache or ScaleOut for distributed caching in geographically distant locations and I would like to know anyone's thoughts who has compared them side by side. I appreciate that many people use one or the other and tell me why their chosen solution is great but I am really looking for a comparison of the two products. Such things as what does AppFabric not do or not do well (if anything), partially from a features point of view but also from developer's point of view. Is working with one compared to the other nicer, easier, more flexible, more powerful, etc. There are plenty of lists of features which I can compare but am really looking for a comparison from someone who has perhaps been in a similar position to us and has performed the evaluation that we are about to launch into which will give us some food for thought whilst we do so. Thanks in advance.

  • SMO missing dll on a clients

    - by Dale
    I've created an app that connects remotely to SQL Server 2008. SQL connections work and all traditional oCommand.ExecuteNonQuery(), work great! But my SMO class using server.ConnectionContext.ExecuteNonQuery(scriptfile); ERROR: missing batch parsing.dll . I can't install these independent utils on a client machines, and then take them all off when done: as suggested by: http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=228de03f-3b5a-428a-923f-58a033d316e1 Since my bulk-inserts are large memory hogs containing complete tables, I wrote the tables to a temptable.sql files and used SQLCMD Util and later switch too SMO and I have the same problem. Neither of these can be leveraged on the client's PCs . Any suggestion? thanks :-)

  • Software to simplify displaying build status on a big visible monitor for team?

    - by MikeJ
    I had a little bit of budget left at year end and I wanted to start a little skunk works project to display build status what everyone was working on (our team is aobut 10 folks all told). I am thinking to buy a 47" LCD HD TV and drive it from a small pc via a browser/.NET web application. I was going to build the software over the christmas break since we are closed for 2 weeks starting this Friday. I thought I would solicit advise/feedback on what other teams had done. a lot of the tools we use SVN, Mantis have RSS feeds that I was thinking to render. Is this the way to go ? Thanks for any feedback in advance.

  • how to automate upsizing from Access to SQL Server?

    - by Arne
    Hi, I need to automate the migration from an Access (2003) to an SQL Server DB (2005 or 2008). The upsizing should be done automatically as part of a build process. I need that because there are 2 versions of the software, a single user rich client and a web version. Access DB is used for single user to minimize setup effort, SQL Server to improve performance and scaling with many simultanious users. Access should be the "leading" DB, meaning devs do changes in Access DB and those are propagated to the SQL server within the build process. Many changes will occur, so doing it manually is not an option. I am new to the Microsoft world, so I dont know appropriate tools for that. What tools can I use and how? I know how to do it (by clicking) with the upsizing assistant. Perhaps I can automate that somehow? Thanks in advance for your answers. Cheers, Arne

  • How to Open a Remote Text File using Server.MapPath in ASP.Net?

    - by NJTechGuy
    This is what I have right now for a file residing on the same server and it works. Dim FILENAME as String = Server.MapPath("Output.txt") Dim objStreamWriter as StreamWriter objStreamWriter = File.CreateText(FILENAME) dr = myCommand.ExecuteReader() While dr.Read() objStreamWriter.WriteLine("{0}|{1}|{2:yyyy-MM-dd}|{3:yyyy-MM-dd}", dr(0), dr(1), dr(2), dr(3)) End While objStreamWriter.Close() I was planning on FTPing the file to another server once done but is there a way to do it on a remote server? i.e create a text file on a remote server and write to it? Did not find any instances of that usage. How to use ServerXMLHTTP to replace Server.MapPath in this instance? Thank you so much for your time.

  • Concurrency Violation in NHibernate( c#) example

    - by vijaysylvester
    For quite some time , I was reading about the optimistic concurrency in NHibernate. If what i understood was correct then the below sample should hold good. Consider two transactions T1 and T2. When T1 and T2 are done simultaneously , the state(DB entries) gets updated with the values of the most latest update.(T1 or T2). Though it seems to be conceptually sound , how do i simulate this for the purpose of understanding and integration testing.? Can someone help me with a sample c# code.? Thanks , vijay
