• Logging NHibernate SQL queries

  - by GuestMVCAsync

  Is there a way to access the full SQL query, including the values, inside my code? I am able to log SQL queries using log4net: <logger name="NHibernate.SQL" additivity="false"> <level value="ALL"/> <appender-ref ref="NHibernateSQLFileLog"/> </logger> However, I would like to find a way to log SQL queries from the code also. This way I will log the specific SQL query that causes an exception in my try/catch statement. Right now I have to data-mine the SQLFileLog to find the query that caused the exception when an exception occurs and it is not efficient.

• Project Euler #163 understanding

  - by Paul

  I spent quite a long time searching for a solution to this problem. I drew tons of cross-hatched triangles, counted the triangles in simple cases, and searched for some sort of pattern. Unfortunately, I hit the wall. I'm pretty sure my programming/math skills did not meet the prereq for this problem. So I found a solution online in order to gain access to the forums. I didn't understand most of the methods at all, and some just seemed too complicated. Can anyone give me an understanding of this problem? One of the methods, found here: http://www.math.uni-bielefeld.de/~sillke/SEQUENCES/grid-triangles (Problem C) allowed for a single function to be used. How did they come up with that solution? At this point, I'd really just like to understand some of the concepts behind this interesting problem. I know looking up the solution was not part of the Euler spirit, but I'm fairly sure I would not have solved this problem anyhow.

• How do I gain permissions to a Sql Compact Database?

  - by Quenton Jones

  I have an Sql Compact Database v3.5 that I'm bundling with my application. When the application is installed, the database is copied into the application's Program Files directory. Because of Vista and Win7's security settings, the installed application can't access the database file. It is merely a problem of having the database file reside in the Program Files. The solution I have thought of is to copy the file into Program Data, but does anyone have another solution? I am sure others have come across a similar problem. Thanks in advance for your input.

• Fetching content from Website on another Server

  - by benny

  Hi everyone. What i basically want to do is to get content from a website and load it into a div of another website. This should be no problem so far. The problem is, that the content that should be fetched is located on a different server and i have no source access to it. I'd prefer a solution using JavaScript of jQuery. Can i use a .htacces redirect to fetch the content from a remote server with client-side (js) techniques? I will also go with other solutions though. Thanks a lot in advance!

• On Linux, how do I run a GUI app from a terminal shell under a different login?

  - by Eric

  Here's the deal. I logged into a Linux box (CentOS, but that shouldn't matter) as user A. I had to build a program as user B, so I started up a terminal shell, logged into that shell as B, and built it. When I try to run the app, I get this message: "connect to ":0.0" refused by server" Most likely because the current X Windows session is owned by user A, and as B, I don't have permissions to access A's stuff. Is there a correct way to solve this. Any incorrect ways?

• BizTalk external assembly namespace and static methods

  - by SteveC

  Is there some restriction in BizTalk 2006 R2 to accessing static methods in external assemblies when the assembly has a "." in the name ? I have the solution set-up with the BizTalk project "FooBar", and the external assembly project "FooBar.Helper" (strongly signed and GAC'ed) with a class "Demo" (public and serializable), which is referenced in the BizTalk project I can create a BizTalk variable of type "FooBar.Helper.Demo" and access an instance method fine, but an expression window the Intellisense shows the FooBar namespace, but if I dot it, I get the error "illegal dotted name" ??? However I can add another project, "ExtComp" with class "Test" and it's static methods are displayed in Intellisense !!! The only difference I can see is the first external assembly has the dot in it

• How do I drop a foerign key in mssql?

  - by mmattax

  I have created a foreign key (in mssql / tsql) by: alter table company add CountryID varchar(3); alter table company add constraint Company_CountryID_FK foreign key(CountryID) references Country; I then run this query: alter table company drop column CountryID; and I get this error: Msg 5074, Level 16, State 4, Line 2 The object 'Company_CountryID_FK' is dependent on column 'CountryID'. Msg 4922, Level 16, State 9, Line 2 ALTER TABLE DROP COLUMN CountryID failed because one or more objects access this column. I have tried this, yet it does not seem to work: alter table company drop foreign key Company_CountryID_FK; alter table company drop column CountryID; What do I need to do to drop the CountryID column? Thanks.

• Core Data and iTunes File Sharing - Move/hide the .sqlite file on app update?

  - by Eric

  I have an iPad app that uses Core Data for data storage. I would like to enable file sharing in iTunes and I don't really want the users to be able to delete or modify the .sqlite file. Can I move the file to a different, hidden directory? Alternatively, could the file be made read-only? I wouldn't mind users having access to the file as long as it couldn't be changed. I suspect there is a trivial solution that is escaping me at the moment.

• Garbage Collection Java

  - by simion

  On the slides i am revising from it says the following; Live objects can be identified either by maintaining a count of the number of references to each object, or by tracing chains of references from the roots. Reference counting is expensive – it needs action every time a reference changes and it doesn’t spot cyclical structures, but it can reclaim space incrementally. Tracing involves identifying live objects only when you need to reclaim space – moving the cost from general access to the time at which the GC runs, typically only when you are out of memory. I understand the principles of why reference counting is expensive but do not understand what "doesn’t spot cyclical structures, but it can reclaim space incrementally." means. Could anyone help me out a little bit please? Thanks

• ORM on iPhone. More simple than CoreData.

  - by Alexander Babaev

  The question is rather simple. I know that there is SQLite. There is Core Data also. But I need something in between. More object-oriented than SQLite API and simplier than Core Data. Main points are: I need access to stored entities only by id. No queries required. I need to store items of a single type, it means that I can use only one table if I choose SQLite. I want automatic object-relational conversion. Or object-storage if the storage is not relational. I can use object archiving, but I have to implement things (NSArchiver). But I want to write some kind of class and get persistence automatically. As it can be done with Hibernate/ActiveRecord/Core Data/etc. Thanks.

• Hibernate database connection configuration

  - by Alvin

  We have 2 different server environments using the same Hibernate configuration. One server has JNDI support for datasource, but the other does not. Currently the Hibernate configuration is configured to use JNDI, which is causing problem on the server that does not support JNDI. I have also tried to put the direct JDBC configuration together with JNDI configuration into the configuration file, but it looks like hibernate always favors JNDI over direct JDBC configuration if both exist. My question is, will it be the same if both JNDI and connection_provider configuration both exists? Will Hibernate still use JNDI over connection_provider? Or is there any way to change the precedence of the database connection property? I do not have access to the server all the time, so I thought I do ask the question before my window of the sever time. Thanks in advance.

• How I Can do web programming with Lisp or Scheme?

  - by Castro

  I usually write web apps in PHP, Ruby or Perl. I am starting the study of Scheme and I want to try some web project with this language. But I can't find what is the best environment for this. I am looking for the following features: A simple way of get the request parameters (something like: get-get #key, get-post #key, get-cookie #key). Mysql access. HTML Form generators, processing, validators, etc. Helpers for filter user input data (something like htmlentities, escape variables for put in queries, etc). FLOSS. And GNU/Linux friendly. So, thanks in advance to all replies.

• Can a proxy server cache SSL GETs? If not, would response body encryption suffice?

  - by Damian Hickey

  Can a (||any) proxy server cache content that is requested by a client over https? As the proxy server can't see the querystring, or the http headers, I reckon they can't. I'm considering a desktop application, run by a number of people behind their companies proxy. This application may access services across the internet and I'd like to take advantage of the in-built internet caching infrastructure for 'reads'. If the caching proxy servers can't cache SSL delivered content, would simply encrypting the content of a response be a viable option? I am considering all GET requests that we wish to be cachable be requested over http with the body encrypted using asymmetric encryption, where each client has the decryption key. Anytime we wish to perform a GET that is not cachable, or a POST operation, it will be performed over SSL.

• Android programming: Authentication and data exchange with Java EE

  - by Konsumierer

  I am having a Java application running in a Tomcat server using Spring, Hibernate, etc. and a two web interfaces, one implemented in Tapestry 5 and the other one using Flex with BlazeDS and Spring-BlazeDS. In my first android application I would now like to log in to the server and retrieve some data. I´m wondering how I could achieve this in a secure way. First of all I need to know which technology is the best to retrieve data from the server and how can I restrict the access to users only that have been successfully authenticated. With what I read until now I would try to implement a HTTPServlet on the server and make server calls via HTTP Client. In the servlet I could probably use the HTTPSession to check if the request comes from an authenticated user. And the data I would try to send serialized (JSON). Unfortunately, I´ve never done those things and maybe I´m on the wrong way and there are more comfortable solutions.

• Python: How can I override one module in a package with a modified version that lives outside the pa

  - by zlovelady

  I would like to update one module in a python package with my own version of the module, with the following conditions: I want my updated module to live outside of the original package (either because I don't have access to the package source, or because I want to keep my local modifications in a separate repo, etc). I want import statements that refer to original package/module to resolve to my local module Here's an example of what I'd like to do using specifics from django, because that's where this problem has arisen for me: Say this is my project structure django/ ... the original, unadulterated django package ... local_django/ conf/ settings.py myproject/ __init__.py myapp/ myfile.py And then in myfile.py # These imports should fetch modules from the original django package from django import models from django.core.urlresolvers import reverse # I would like this following import statement to grab a custom version of settings # that I define in local_django/conf/settings.py from django.conf import settings def foo(): return settings.some_setting Can I do some magic with the __import__ statement in myproject/__init__.py to accomplish this? Is there a more "pythonic" way to achieve this?

• Which libraries use the "We Know Where You Live" optimization for std::make_shared?

  - by KnowItAllWannabe

  Over two years ago, Stephan T. Lavavej described a space-saving optimization he implemented in Microsoft's implementation of std::make_shared, and I know from speaking with him that Microsoft has nothing against other library implementations adopting this optimization. If you know for sure whether other libraries (e.g., for Gnu C++, Clang, Intel C++, plus Boost (for boost::make_shared)) have adopted this implementation, please contribute an answer. I don't have ready access to that many make_shared implementations, nor am I wild about digging into the bowels of the ones I have to see if they've implemented the WKWYL optimization, but I'm hoping that SO readers know the answers for some libraries off-hand. I know from looking at the code that as of Boost 1.52, the WKWYL optimization had not been implemented, but Boost is now up to version 1.55. Note that this optimization is different from std::make_shared's ability to avoid a dedicated heap allocation for the reference count used by std::shared_ptr. For a discussion of the difference between WKWYL and that optimication, consult this question.

• Manipulating excel "autoshapes" with VBA

  - by AME

  I am trying to write a macro in VBA (Excel) that is assigned to a Checkbox. Whenever the checkbox is clicked, an "autoshape" will change its "order" from "Send to Back" to "Send to Front". Basically, I am trying to create a dashboard with multiple panels, so that users can access information without moving between sheets. Each panel will have a rectangular autoshape as its background and the components of the panel will be "grouped" within the autoshape. Can this be done? I would greatly appreciate any ideas into writing the code. Thanks,

• Write a dll that is accessable from VS 2003 VC++ code

  - by John

  I need to be able to write a DLL in either C# or VC++ that is accessible from code that is written in Visual Studio 2003 VC++. It looks like the code is unmanaged (uses * for pointers) VC++ and this DLL needs to be able to drop right in and be accessed by the current code. The DLL is an RS232 driver that needs to be able to return an int for an error code and pass back, by reference, some measured values, to the calling program. Will I even be able to write this in C#? If not, I only have access to Visual Studio 2005 or 2008. Will I be able to write my code in either, and will that DLL be able to be called from the current code base? Or do I have to go looking on ebay for a copy of VS 2003?

• Attaching catalog with SQL Authentication credentials attaches it as Read-Only

  - by Nissim

  Hello, As part of our product's installation process, a database is attached to the server. We use EXEC sp_attach_db in order to attach it to MSSQL. The problem occures when we try to attach it with "SQL Authentication" connection string - the database is attached to the server as read-only, thus preventing any write access from being performed This is driving us nuts... it's working just fine with Windows Authentication, and the only difference is the connection string... I tried googling for it but no mention for such a scenario is found. Any ideas anyone? It's important to mention that the MDF/LDF physical files are not set with "ReadOnly" attribute, so this is not the problem.

• IPhone: different system timers??

  - by matt

  I have been using mach_absolute_time() for all my timing functions so far. calculating how long between frames ect. I now want to get the exact time touch input events happen using event.timestamp in the touch callbacks. the problem is these two seem to use completely different timers. sure, you can get them both in seconds, but their origins are different and seemingly random... is there any way to sync the two different timers? or is there anyway to get access to the same timer that the touch input uses to generate that timestamp property? otherwise its next to useless.

• Secure Gmail login on web browser from external Java program

  - by Zach Scrivena

  Is there a secure way of logging into a Gmail account on a web browser, from an external Java program? I know the following works, but is there a safer alternative? Desktop.getDesktop().browse(new URI( "https://www.google.com/accounts/ServiceLoginAuth?continue=http://mail.google.com/gmail" + "&service=mail&Email=LOGIN&Passwd=PASSWORD&null=Sign+in")); Clarification: The external Java program is GmailAssistant, a Gmail notifier that already uses the IMAP capabilities of JavaMail. I just need a way of allowing the user to access the account directly in a web browser.

• Semicolon in object variable name

  - by milkfilk

  There's a common LDAP attribute called userCertificate;binary. It actually has a semi-colon in the attribute name. In ruby, I turn an LDAP entry into a OpenStruct object called 'struct'. struct.class = OpenStruct But of course ruby thinks it's an end-of-line character. ? struct.userCertificate;binary NameError: undefined local variable or method `binary' for main:Object from (irb):52 from :0 IRB knows that the local variable is there, because it gives me struct.userCertificate;binary from the tab auto-completion. I can also see the class variable when calling struct.methods on it. struct.methods = ... "send", "methods", "userCertificate;binary=", "hash", ... It's definitely there, I can see the contents if I print the whole variable to_s(). But how can I access the local variable when it has a semicolon in it? I have workarounds for this but I thought it was an interesting problem to post.

• Explicitly typing variables causes compiler to think an instance of a builtin type doesn't have a pr

  - by wallacoloo

  I narrowed the causes of an AS3 compiler error 1119 down to code that looks similar to this: var test_inst:Number = 2.953; trace(test_inst); trace(test_inst.constructor); I get the error "1119: Access of possibly undefined property constructor through a reference with static type Number." Now if I omit the variable's type, I don't get that error: var test_inst = 2.953; trace(test_inst); trace(test_inst.constructor); it produces the expected output: 2.953 [class Number] So what's the deal? I like explicitly typing variables, so is there any way to solve this error other than not providing the variable's type?

• Net Neutrality FAIL [closed]

  - by leeand00

  I know I'll get into all kinds of trouble for bringing this up on SO, but considering that nearly all of us programmers depend on the Internet to get our jobs done, I really think it's worth looking into today's failure of our right to use the Internet by way of Lobbying ISPs. Although something tells me there will be retribution for the actions of the ISPs/tel cos/cable and their lobbyist since, lets face it...ISPs/Telcos didn't invent the Internet. I'm not going to be the one to do it, but um I think somebody already has...as everybody I talked to was having Internet connection problems today at work. Just thought this might be relevant to all of our jobs...in the U.S.A. at least. If you work at an Big evil ISPs, by all means...try and close this question. If you don't...and your just a chap who enjoys your Internet access...please RT this: Contact The Democrats Who Are Against Net Neutrality (Full List W/ Contact Info) http://bit.ly/aMSV0W #NetNeutralityFAIL net-neutrality
