  • Can I write for .Net 4 using VS2008?

    - by chillitom
    Can I write code against .Net 4 and its libraries using VS2008? If so how should I configure it? I realise that VS2008 will probably struggle with language changes such as the dynamic keyword but can I install the version 4 and target it anyway? My only real interest is in being able to use some of the new libraries, in particular I'm interested in the TPL (http://en.wikipedia.org/wiki/Parallel_Extensions)

  • Multithreaded Haskell

    - by Ingdas
    Hi I'm learning Haskell and I'd like to write some multithreaded programs now to see the performance gains from that in a functional language. I can find some references to it on the internet but never a proper introduction to it. Can anyone point me to a guide which is understandable for someone who knows the syntax fairly well, but is not a wizard in Haskell?

  • Regex: How do I match some regex logic 1 or more times?

    - by tom
    I already have some regex logic which says to look for a div tag with class=something. However, this might occur more than once (one after another). You can't simply add square brackets around that complex regex logic already (e.g. [:some complicated regex logic already existing:]* -- so how do you do it in regex? I want to avoid having to use the programming language logic to append that regex logic after itself if I can... Thanks

  • Localizing MVVM based WPF applications

    - by bitbonk
    What would be a good aproach to localize a MVVM based WPF allication that can change its language at runtime? Of course I could create a string property in the ViewModel for each and every string that is displayed somewhere in the View but that seems rather tedious to me. Is there a common approach/best practice for this?

  • Programicaly measure size and way-order of L1 and L2 caches

    - by osgx
    Hello How can I measure programicaly (not query the OS, but measure) the size and order of associativity of L1 and L2 caches (data caches)? Assumtions about system: It has L1 and L2 cache (may be L3 too, may be cache sharing), It may have a hardware prefetch unit (just like P4+), it has a stable clocksource (tickcounter or good HPET for gettimeofday). There are no assumtions about OS (it can be Linux, Windows, smth non-standart), and we can't use posix queries. Language is C. And Compiler optimizations may be disabled.

  • Send smtp mail in php with HTML page attach as a text

    - by Nirmal
    Hello All.... I have a requirement of sending mail using smtp server in php. Now I am able to send the mail using smtp for a plain text. but I have a requirement where I need to attach an HTML page, which includes set of images. Now for that I am trying the following code : <?php require_once "Mail.php"; $to = '[email protected]'; $from = '[email protected]'; $subject = $_POST['subject']; $body = $_POST['message']; $fileatt = $_FILES['fileatt']['tmp_name']; $fileatt_type = $_FILES['fileatt']['type']; $fileatt_name = $_FILES['fileatt']['name']; $headers = array ('From' => $from, 'To' => $to, 'Subject' => $subject); if (is_uploaded_file($fileatt)) { echo("<p>Inside 1</p>"); $file = fopen($fileatt,'rb'); $data = fread($file,filesize($fileatt)); fclose($file); // Generate a boundary string $semi_rand = md5(time()); $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; array_push(&$headers, 'MIME-Version: 1.0'); array_push(&$headers, 'Content-Type: multipart/mixed;'); array_push(&$headers, " boundary=\"{$mime_boundary}\""); echo("<p>Inside 2</p>"); $body = "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type: text/plain; charset=\"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $body . "\n\n"; echo("<p>Inside 3</p>"); $data = chunk_split(base64_encode($data)); echo("<p>Inside 4</p>"); $body .= "--{$mime_boundary}\n" . "Content-Type: {$fileatt_type};\n" . " name=\"{$fileatt_name}\"\n" . "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n" . "--{$mime_boundary}--\n"; echo("<p>Inside 5</p>"); } $host = "[email protected]"; $username = "[email protected]"; $password = "user"; $smtp = Mail::factory('smtp', array ('host' => $host, 'auth' => true, 'username' => $username, 'password' => $password)); $mail = $smtp->send($to, $headers, $body); if (PEAR::isError($mail)) { echo("<p>" . $mail->getMessage() . "</p>"); } else { echo("<p>Message successfully sent!</p>"); } ?> Now this code works fine for me, and it's sending the mail to the target email address. But when I open this email in the inbox, it's showing me the following text in the mailbox: This is a multi-part message in MIME format. --==Multipart_Boundary_x368d72fe1ff44518e90537abdb4bf029x Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit test 1011 --==Multipart_Boundary_x368d72fe1ff44518e90537abdb4bf029x Content-Type: text/html; name="mailing.html" Content-Transfer-Encoding: base64 PCFET0NUWVBFIGh0bWwgUFVCTElDICItLy9XM0MvL0RURCBYSFRNTCAxLjAgVHJhbnNpdGlvbmFs Ly9FTiIgImh0dHA6Ly93d3cudzMub3JnL1RSL3hodG1sMS9EVEQveGh0bWwxLXRyYW5zaXRpb25h ................ So, it's clearly showing me the encoded data. So, what should modify to send the proper html page that should be visible in targeted email's inbox? Thanks in advance...

  • working on lists in python

    - by owca
    I'm trying to make a small modification to django lfs project, that will allow me to deactivate products with no stocks. Unfortunatelly I'm just beginning to learn python, so I have big trouble with its syntax. That's what I'm trying to do. I'm using method 'has_variants' which returns true if product has any. Then I'm building a list from variants for this product. Next for every product in this list (I've called it 'set') I check it's stock and set bool variable 'inactive' to true if product has no stocks and to false if there are any. Finally if 'inactive' is false I'm setting self.active to 0. Code fails in line with: set[] = s How to correct it ? def deactivate(self): """If there are no stocks, deactivate the product. Used in last step of checkout. """ if self.has_variants(): for s in self.variants.filter(active=True): set[] = s for var in set: if var.get_stock_amount() == 0: inactive = True else: inactive = False else: if self.get_stock_amount() == 0: inactive = True if inactive: self.active = False return 0 error log : Traceback (most recent call last): File "manage.py", line 11, in <module> execute_manager(settings) File "/home/purplecow/rails/purpledev/site-packages/django/core/management/__i nit__.py", line 362, in execute_manager utility.execute() File "/home/purplecow/rails/purpledev/site-packages/django/core/management/__i nit__.py", line 303, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/home/purplecow/rails/purpledev/site-packages/django/core/management/bas e.py", line 195, in run_from_argv self.execute(*args, **options.__dict__) File "/home/purplecow/rails/purpledev/site-packages/django/core/management/bas e.py", line 213, in execute translation.activate('en-us') File "/home/purplecow/rails/purpledev/site-packages/django/utils/translation/_ _init__.py", line 73, in activate return real_activate(language) File "/home/purplecow/rails/purpledev/site-packages/django/utils/translation/_ _init__.py", line 43, in delayed_loader return g['real_%s' % caller](*args, **kwargs) File "/home/purplecow/rails/purpledev/site-packages/django/utils/translation/t rans_real.py", line 205, in activate _active[currentThread()] = translation(language) File "/home/purplecow/rails/purpledev/site-packages/django/utils/translation/t rans_real.py", line 194, in translation default_translation = _fetch(settings.LANGUAGE_CODE) File "/home/purplecow/rails/purpledev/site-packages/django/utils/translation/t rans_real.py", line 180, in _fetch app = import_module(appname) File "/home/purplecow/rails/purpledev/site-packages/django/utils/importlib.py" , line 35, in import_module __import__(name) File "/home/purplecow/rails/purpledev/lfs/caching/__init__.py", line 1, in <mo dule> from listeners import * File "/home/purplecow/rails/purpledev/lfs/caching/listeners.py", line 10, in < module> from lfs.cart.models import Cart File "/home/purplecow/rails/purpledev/lfs/cart/models.py", line 8, in <module> from lfs.catalog.models import Product File "/home/purplecow/rails/purpledev/lfs/catalog/__init__.py", line 1, in <mo dule> from listeners import * File "/home/purplecow/rails/purpledev/lfs/catalog/listeners.py", line 5, in <m odule> from lfs.catalog.models import PropertyGroup File "/home/purplecow/rails/purpledev/lfs/catalog/models.py", line 589 set[] = s ^ SyntaxError: invalid syntax

  • How can I list the properties of an object programmatically in VB6?

    - by Gregory Higley
    A friend of mine is working on a legacy VB6 project. I haven't touched that language in ten years, so I'm pretty rusty. Anyway, is there any kind of reflection API for VB6? Specifically, he needs a way to iterate the properties (and types) of a user-created Class. (In other words, not an external COM object, but an internal "Class Module" as it's called.) How can this be done?

  • Why can't I inherit static classes?

    - by User
    I have several classes that do not really need any state. From the organizational point of view, I would like to put them into hierarchy. But it seems I can't declare inheritance for static classes. Something like that: public static class Base { } public static class Inherited : Base { } will not work. Why have the designers of the language closed that possibility?

    I want to know how to open and manipulate a simple image file in Ruby language. I don't need to do any advanced stuff, just things like open(), get_pixel() and put_pixel() and I don't wanna use any gem for doing that, but just to know the barehands-ruby way.

  • Catching typos in scripting languages

    - by Geo
    If your scripting language of choice doesn't have something like Perl's strict mode, how are you catching typos? Are you unit testing everything? Every constructor, every method? Is this the only way to go about it?

  • Is there any working implementation of reverse mode automatic differentiation for Haskell?

    - by Ian Fiske
    The closest-related implementation in Haskell I have seen is the forward mode at http://hackage.haskell.org/packages/archive/fad/1.0/doc/html/Numeric-FAD.html. The closest related related research appears to be reverse mode for another functional language related to Scheme at http://www.bcl.hamilton.ie/~qobi/stalingrad/. I see reverse mode in Haskell as kind of a holy grail for a lot of tasks, with the hopes that it could use Haskell's nested data parallelism to gain a nice speedup in heavy numerical optimization.

  • force other screen on boot

    - by PaoloFCantoni
    I have a multi-boot Windows 7 (32bit & 64 bit) on my HP Notebook. Unfortunately, the Notebook screen has been trashed (due to daughter dropping it). So I have attached a second screen. On the 64 bit system, after windows has started, the logon screen comes up on the 2nd monitor just fine. On the 32 bit system, the logon screen still comes up on the Notebook monitor and I have to open the lid, and shut it so that it then switches to the attached screen. In both cases the display has been set to only display on the attached screen (ie if I "identify" the attached screen says: '1'). Is there any setting I can use to force the OS to use the attached screen? TIA, Paolo

  • Automatic bookkeeping for exception retries

    - by pilcrow
    Do any languages that support retry constructs in exception handling track and expose the number of times their catch/rescue (and/or try/begin) blocks have been executed in a particular run? I find myself counting (and limiting) the number of times a code block is re-executed after an exception often enough that this would be a handy language built-in.

  • Nagios Check_hpjd giving me problems!

    - by Mister IT Guru
    When I run the following [root@host plugins]# ./check_hpjd -H printer1.mydomain.com : Timeout from host printer1.mydomain.com I have Net-snmp installed on my system, I noted that i didn't have net-snmp-utils installed, and then I was able to run [root@host plugins]# snmpwalk -Os -c public -v 1 printer1.mydomain.com system sysDescr.0 = STRING: HP ETHERNET MULTI-ENVIRONMENT sysObjectID.0 = OID: enterprises.11.2.3.9.1 sysUpTimeInstance = Timeticks: (325408663) 37 days, 15:54:46.63 sysContact.0 = STRING: sysName.0 = STRING: printer1 sysLocation.0 = STRING: sysServices.0 = INTEGER: 72 So I know that the printer is working as expected, (as far as SNMP is concerned). But when I run [root@host plugins]# ./check_hpjd -H printer1.mydomain.com -C public Error in packet () I get this error - From what I've tried so far, I know my host can communicate via SNMP, I know the printer responds via SNMP, so I guess I'm left to look at the plug-in, which I will be checking up on. I'm new to SNMP, I am investigating this with my good friend Google search, but I am on a learning curve here, so please forgive my questions if they sound stupid,

  • Colour instead of color?

    - by Jookia
    I'm working on a game engine in C++ and I have methods like setColour and things that use british grammar. While I was thinking how C++ compilers mostly use the english language (correct me if I'm wrong) and how most APIs use american grammar, should I go with the flow and continue the unofficial standard in the grammar programmer high council or be a rebel? I'm not sure which.

  • Looking for a free xsd scheme editor

    - by Klaim
    I'm looking for a free alternative to all the XML/XSD editors around here (that are relatively expensive--at least for me). I totally fail to find one. I need it to allow me to edit xsd files to help in writting an xml-based language specification. I need it to be visual to help with the design, making it clear. Other features are less interesting for me. Any suggestion?

  • Modern monitor technologies - need to find a new monitor

    - by Michal Minicki
    I'm preparing to change my old LCD monitor for a new one. I have an old NEC 20WGX2 Pro based on an IPS panel. I'm looking for a screen that gives good color output but is very good at gaming at the same time (since it is its primary service). I tend to switch monitors between my different computers at home so it has to be multi purpose, hence IPS technology before. Now, where can I read on newest monitor technologies so I can make an informed decision? I need to find a best fit for myself and I have a very outdated knowledge at the moment. So any hints are greatly appreciated, be it info on technologies, web sources, links to other questions, etc.

  • Author Tools for Classroom Material?

    - by user1413
    I'm interested in putting a whole bunch of classroom material online. This material ranges from accounting classes to yoga. I would like to find a simple to use authoring tool that the people who teach the classes can use to put the material online. In other words, I do not want a tool that requires a developer. A person who knows the subject matter and is willing to read the manual should be able to put their material online. At minimum, this tool should allow for text and multi-media to be chained together in a logical form and it should allow quizzes to be created and graded. Even better would be for the tool to have some "smarts" so that subject areas which the student does not understand can be drilled. Even better would be for the tool to have ecommerce built in so that the instructors can charge for the classes. Are there any such tools?

  • Nintendo DSi SDK : Getting Started

    - by Hugoware
    Does anyone have a good starting point for learning about development for the new Nintendo DSi? What kind of hardware do you need to develop and test something like this? Can you develop for the DSi using the standard DS? What language do you need to use? [Bonus Question] : I also heard the new DSi is going to get an App Store similar to Apple - Are developers going to be able to sell games using this?
