  • Can I automate the finding of -l parameter I use when linking based on header files (gcc)?

    - by kavic
    Normally when linking against a static library, I have to specify a library directory and the name of a libX.so (or its symbolic link) as -lX flag for linking [and its directory with -L flag]. Can I automate this based on my header files (in c/c++) only? Or maybe it is not a good idea? Is there a software for locating the -L and -l parameters automatically? Is some table stored somewhere on the system about this on popular linux systems or even cygwin?

  • SQL: how to get the left 3 numbers from an int

    - by dmr
    I want to retrieve the left 3 numbers from an integer to be stored in a table. For example, if the int is 1234567, I want to retrieve 123. I want the second number (123) to also be an int; I don't want to convert anything to a string. (And yes, really I should be working with strings. But I don't have control over that aspect of the issue.) Thank you!

  • Cloning a Windows server with VMWare ESXi without domain membership conflicts

    - by Brad
    We are using VMWare ESXi 3.5, and have found it quite useful for cloning a live server to then use the virtualized version to test/practice software upgrades. The trouble is, when the virtualized version fires up, it registers itself on our domain (Active Directory), causing the original server to no longer be accessible via Windows shares. The fix is to remove the virtualized version from the domain, configuring it to use a workgroup instead, deleting the Computer account in AD, and then removing the real server from the domain and re-adding it. Is there a better procedure? Note, we cannot simply disconnect the virtual network from the virtualized server, as it needs to be connected to the network to actually be removed from the domain.

  • Loading the last related record instantly for multiple parent records using Entity framework

    - by Guillaume Schuermans
    Does anyone know a good approach using Entity Framework for the problem described below? I am trying for our next release to come up with a performant way to show the placed orders for the logged on customer. Of course paging is always a good technique to use when a lot of data is available I would like to see an answer without any paging techniques. Here's the story: a customer places an order which gets an orderstatus = PENDING. Depending on some strategy we move that order up the chain in order to get it APPROVED. Every change of status is logged so we can see a trace for statusses and maybe even an extra line of comment per status which can provide some extra valuable information to whoever sees this order in an interface. So an Order is linked to a Customer. One order can have multiple orderstatusses stored in OrderStatusHistory. In my testscenario I am using a customer which has 100+ Orders each with about 5 records in the OrderStatusHistory-table. I would for now like to see all orders in one page not using paging where for each Order I show the last relevant Status and the extra comment (if there is any for this last status; both fields coming from OrderStatusHistory; the record with the highest Id for the given OrderId). There are multiple scenarios I have tried, but I would like to see any potential other solutions or comments on the things I have already tried. Trying to do Include() when getting Orders but this still results in multiple queries launched on the database. Each order triggers an extra query to the database to get all orderstatusses in the history table. So all statusses are queried here instead of just returning the last relevant one, plus 100 extra queries are launched for 100 orders. You can imagine the problem when there are 100000+ orders in the database. Having 2 computed columns on the database: LastStatus, LastStatusInformation and a regular Linq-Query which gets those columns which are available through the Entity-model. The problem with this approach is the fact that those computed columns are determined using a scalar function which can not be changed without removing the formula from the computed column, etc... In the end I am very familiar with SQL and Stored procedures, but since the rest of the data-layer uses Entity Framework I would like to stick to it as long as possible, even though I have my doubts about performance. Using the SQL approach I would write something like this: WITH cte (RN, OrderId, [Status], Information) AS ( SELECT ROW_NUMBER() OVER (PARTITION BY OrderId ORDER BY Id DESC), OrderId, [Status], Information FROM OrderStatus ) SELECT o.Id, cte.[Status], cte.Information AS StatusInformation, o.* FROM [Order] o INNER JOIN cte ON o.Id = cte.OrderId AND cte.RN = 1 WHERE CustomerId = @CustomerId ORDER BY 1 DESC; which returns all orders for the customer with the statusinformation provided by the Common Table Expression. Does anyone know a good approach using Entity Framework?

  • how to make oracle case insensitive

    - by yuri
    Can there be a setting on Oracle 10g to consider data as case insensitive? I saw a solution here. However, that is done on a session. What I am looking for is a setting either on a schema or on a table to consider it's data as case insensitive. If it is on a session then I will have to make the change on all the stored procedures.

  • MultiOS "Jet Database" for C++/Qt?

    - by Airjoe
    Hopefully I can articulate this well: I'm porting an application I made years ago from VB6 (I know, I know!) to C++/Qt. In my original application, one thing I liked was that I didn't need an actual SQL server running, I could just use MS Access .mdb files. I was wondering if something similar exists for Qt that will work on multiple OSes - a database stored in a file, pretty much, but that I can still run SQL queries with. Not sure if something like this exists or not, but any help appreciated, thanks!

  • Should HTML be encoded before being persisted?

    - by Sir Psycho
    Should HTML be encoded before being stored in say, a database? Or is it normal practice to encode on its way out to the browser? Should all my text based field lengths be quadrupled in the database to allow for extra storage? Looking for best practice rather than a solid yes or no :-)

  • Dump Microsoft SQL Server database to an SQL script

    - by Matt Sheppard
    Is there any way to export a Microsoft SQL Server database to an sql script? I'm looking for something which behaves similarly to mysqldump, taking a database name, and producing a single script which will recreate all the tables, stored procedures, reinsert all the data etc. I've seen http://vyaskn.tripod.com/code.htm#inserts, but I ideally want something to recreate everything (not just the data) which works in a single step to produce the final script.

  • How can I check a radio button on load, based on it's value?

    - by Noor
    I've got the value of a radio button (r1) and I'm trying to use: $("input:radio[val=r1]").attr('checked', true); to check it. The thing is that I've got three radio buttons in a div, when I check one, the value of the checked button gets stored. When I reload the page I want the page to check the radio button that was chosen last. Thanks!

  • Database backup regardless of backup made through a control panel?

    - by developer
    I know that all CMS or CMC platforms have some sort of walkthrough for their users to fully backup and restore the database or the whole website. While we all can perform such backups (and there are even plugins which automate the whole procedure) and restore them in necessity (such as when we migrate to a new server), one can also backup the whole website by means of such control panels as Directadmin or Cpanel. Now, I just want to know if it is necessary for us to do database or website backups the way they are described by a specific CMC or CMS developer even after we perform a whole website backup in a control panel such as DA? An example of such CMS platforms is moodle. Moodle Docs describes how we can backup and restore moodle in here. So do we, out of necessity, have to make the backup the way described, or we can simply do it the Control panel way? Thanks

  • Windows 7 Public Documents Folder - how to move it to drive d:

    - by Bazza Formez
    Hi, I've just bought a new pc, and it is running Windows 7. I'm wanting to set up all of the documents folders such that they point to folders on a second drive partition (ie. disk D:) so that I have a nice separation of os from docs. I have managed to do this for each user on the machine (by opening up properties for documents folder and changing location). Hwoever, this procedure doesn't seem to work for the public documents folder. I cannot change the location for that one (even though I have administrator privileges). It is greyed out and cannot be changed. Any ideas ? Thanks!!

  • Tips for documenting a web application?

    - by Pandiya Chendur
    I know that I can take my asp.net application and get it reversed to a UML document, but that doesn't tell the whole story of things like who can use what, what it calls in the way of stored procedures, what pages call what pages etc. etc. Does anyone know of an article where someone has a comprehensive way to document a web application/site? Or shall I just make up my own way?

  • Scope of Derived Tables in SQL Server

    - by FailBoy
    I've been looking into SQL recently and exploring a bit. in regards to Temp Tables I have discovered 3 different temp table types: 1) CREATE TABLE #TempTable 2) DECLARE TABLE @TempTable 3) SELECT * FROM (SELECT * FROM Customers) AS TempTable Now I understand the scope behind the #TempTable and the @TempTable types, but what about the derived table as in example 3? Where does this derived table get stored? and if it is declared in 1 transaction, can a 2nd transaction access it, or is the scoping of Derived Tables that same as example 1 and 2?

  • login as rsh in rhel 6 without entering password

    - by cartmancakes
    I need to be able to login to a RHEL 6 server using rsh (please don't flame me about security, it's irrelevant in this particular instance) as root without having to enter a password. My procedure for setting this up works great in RHEL 5.x, but does not work in RHEL 6. I suspect this has something to do with PAM, but I'm inexperienced with how to use PAM. Can someone help me with this? /etc/pam.d/rsh auth required pam_rhosts.so auth required pam_nologin.so account include common-account password include common-password session required pam_loginuid.so session include common-session /etc/pam.d/rlogin auth required pam_nologin.so auth [user_unknown=ignore success=ok ignore=ignore auth_err=die default=bad] pam_securetty.so auth sufficient pam_rhosts.so auth include common-auth auth required pam_mail.so account include common-account password include common-password session required pam_loginuid.so session include common-session Thanks!
