• Are there any utilities to extract binary data from MSSQL Server

  - by Sean Taylor

  Hi, Are there any utilities available that allow you to bulk extract binary data from a MSSQL table? For example, I have a number of Word documents stored in a table and I would like to extract all of these documents into files. I know could do this by writing some .NET code, but I only need to do it once.

• Help Finding Memory Leak

  - by Neal L

  Hi all, I am writing an iPad app that downloads a rather large .csv file and parses the file into objects stored in Core Data. The program keeps crashing, and I've run it along with the Allocations performance tool and can see that it's eating up memory. Nothing is alloc'ed or init'ed in the code, so why am I gobbling up memory? Code at: http://pastie.org/955960 Thanks! -Neal

• Accessing the MSP and PSP registers of the Cortex-M3 in C/C++ code using Keil's µVision

  - by Captain NedD

  I need to access the MSP and PSP registers (the main and process stack registers) of the Cortex-M3 processor. I'm writing in C/C++. The µVision and associated compiler doesn't let you do inline assembly for this Thumb-2 only core (and I'm not sure that'd be such a good idea anyway). I need to do this so that I can extract the immediate value of an svc instruction regardless of whether it was executed while in thread or handler mode. Thanks,

• How to write text files with DOS line endings on linux

  - by gaumann

  I want to write text files with DOS/Windows line endings '\r\n' using python running on Linux. It seems to me that there must be a better way than manually putting a '\r\n' at the end of every line or using a line ending conversion utility. Ideally I would like to be able to do something like assign to os.linesep the separator that I want to use when writing the file. Or specify the line separator when I open the file.

• How to convert closed bezier curves to Bitmaps?

  - by Sorush Rabiee

  I need an algorithm to convert a closed bezier curve (perhaps self-crossing) to a binary bitmap: 0 for inside pixels and 1 for outside. I'm writing a code that needs to implement some operations on bezier curves, could anybody give me some resources or tutorials about beziere? Wikipedia and others didn't say anything about optimization, subtracting, union, knot insertion and deletion and other operations :-)

• How to detect Java agents, JVMTI, etc...

  - by Andrew Westberg

  How does one secure the Java environment when running on a machine you don't control? What is to stop someone from creating a java agent or native JVMTI agent and dumping bytecode or re-writing classes to bypass licensing and/or other security checks? Is there any way to detect if any agents are running from Java code? From JNI? From a JVMTI agent?

• Drupal Module Themes - Default CSS?

  - by derekerdmann

  There's tons of documentation out there on how to override the appearance of Drupal modules, but I keep finding the docs for writing the original theme to be a little lacking. On this note, how can I tell Drupal to use a specific CSS file for my custom module's block output?

• How to check Linux version with Autoconf?

  - by Goofy

  My program requires at least Linux 2.6.26 (I use timerfd and some other Linux-specific features). I have an general idea how to write this macro but I don't have enough knowledge about writing test macros for Autoconf. Algorithm: Run "uname --release" and store output Parse output and subtract Linux version number (MAJOR.MINOR.MICRO) Compare version I don't know how to run command, store output and parse it. Maybe such macro already exists and it's available (I haven't found any)?

• Pythonic / itertools way to go through a dict?

  - by dmd

  def reportCSV(t): ret = '' for ev in t: for p in t[ev]: for w in t[ev][p]: ret += ','.join((ev, p, w, t[ev][p][w])) + '\n' return ret What is a more pythonic way to do this, e.g. using itertools or the like? In this case I'm just writing it out to a CSV file. t is a dict t[ev] is a dict t[ev][p] is a dict t[ev][p][w] is a float I'm not sure how I'd use itertools.product in this case.

• Is there a special character in mySql that would return always true in WHERE clauses?

  - by rm.

  Is there a character, say, $, SELECT * FROM Persons WHERE firstName='Peter' AND areaCode=$; such that the statement would return the same as SELECT * FROM Persons WHERE firstName='Peter' i.e. areaCode=$ would always return always true and, thus, effectively “turns of” the criteria areaCode=... I’m writing a VBA code in Excel that fetches some rows based on a number of criteria. The criteria can either be enabled or disabled. A character like $ would make the disabling so much easier.

• Should a managed class that wraps a DirectSound interface be IDisposable?

  - by CannibalSmith

  I'm writing a managed wrapper around DirectSound. (It's a simple partial wrapper that solves my specific problem and nothing more. Don't tell me about NAudio or whatever.) Should a managed class that wraps IDirectSound8 be IDisposable and why? Same question about IDirectSoundBuffer8.

• Correct order of overrides for a composite control based on an abstract one

  - by mattdwen

  I'm writing a set of C# composite web server controls for displaying dialog boxes. I want to have one abstract class which handles the basic layout and things like titles of the control, then have a set of derived ones which render child controls at a specific point. I forsee three distincts methods: renderOpeningHtml handled by the abstract class, renderCustomControls as done by the derived class, and renderClosingHtml by the abstract class again, except I can't figure the life cycle of a CompositeControl and what methods to use when.

• WM6.5 embedded Internet Explorer finder scrolling

  - by Aaron

  I'm writing a .NET 3.5 application targetted for Windows Mobile 6.5. My application uses an embedded IE control to display content. The IE application allows the user to finger scroll around the webpage (i.e. touch the screen and drag instead of using the scrollbar). My IE control has a scrollbar and when I emulate the gesture, I highlight text instead of scrolling. Is there a way to add finger gesture support to an embedded IE control? Thanks, Aaron

• What privileges do I need?

  - by IAbstract

  I have a Windows service that isn't writing to the Application Event log under UserAccount. When the service is set to use AdminAccount, the Security log reports the following attributes: Under UserAccount, the only privilege reported is SeImpersonatePrivilege. Is there a security impersonation that I can implement to give the UserAccount the ability to write to the Application Event log? I would prefer to use the UserAccount for this service rather than the AdminAccount.
