• C#. Where struct methods code kept in memory?

  - by maxima120

  It is somewhat known where .NET keeps value types in memory (mostly in stack but could be in heap in certain circumstances etc)... My question is - where is the code of the struct? If I have say 16 byte of data fields in the struct and a massive computation method in it - I am presuming that 16 byte will be copied in stack and the method code is stored somewhere else and is shared for all instances of the struct. Are these presumptions correct?

• Subversion with Apache and permissions issues

  - by djechelon

  Hello, I have setup an SVN repository for use with Apache 2 via svnadmin create command and appropriate vhost configuration. I found that, in order to correctly use the repository, this must be owned by wwwrun user (or www group) or chmodded to 777. I would like to ask if it's possible to explicitly tell Apache to impersonate another user when serving requests to a certain path (from vhost.conf), like with suphp extension, so I won't mess with permissions once I create a repository. Thank you in advance

• How can I enable a debugging mode via a command-line switch for my Perl program?

  - by Michael Mao

  I am learning Perl in a "head-first" manner. I am absolutely a newbie in this language: I am trying to have a debug_mode switch from CLI which can be used to control how my script works, by switching certain subroutines "on and off". And below is what I've got so far: #!/usr/bin/perl -s -w # purpose : make subroutine execution optional, # which is depending on a CLI switch flag use strict; use warnings; use constant DEBUG_VERBOSE => "v"; use constant DEBUG_SUPPRESS_ERROR_MSGS => "s"; use constant DEBUG_IGNORE_VALIDATION => "i"; use constant DEBUG_SETPPING_COMPUTATION => "c"; our ($debug_mode); mainMethod(); sub mainMethod # () { if(!$debug_mode) { print "debug_mode is OFF\n"; } elsif($debug_mode) { print "debug_mode is ON\n"; } else { print "OMG!\n"; exit -1; } checkArgv(); printErrorMsg("Error_Code_123", "Parsing Error at..."); verbose(); } sub checkArgv #() { print ("Number of ARGV : ".(1 + $#ARGV)."\n"); } sub printErrorMsg # ($error_code, $error_msg, ..) { if(defined($debug_mode) && !($debug_mode =~ DEBUG_SUPPRESS_ERROR_MSGS)) { print "You can only see me if -debug_mode is NOT set". " to DEBUG_SUPPRESS_ERROR_MSGS\n"; die("terminated prematurely...\n") and exit -1; } } sub verbose # () { if(defined($debug_mode) && ($debug_mode =~ DEBUG_VERBOSE)) { print "Blah blah blah...\n"; } } So far as I can tell, at least it works...: the -debug_mode switch doesn't interfere with normal ARGV the following commandlines work: ./optional.pl ./optional.pl -debug_mode ./optional.pl -debug_mode=v ./optional.pl -debug_mode=s However, I am puzzled when multiple debug_modes are "mixed", such as: ./optional.pl -debug_mode=sv ./optional.pl -debug_mode=vs I don't understand why the above lines of code "magically works". I see both of the "DEBUG_VERBOS" and "DEBUG_SUPPRESS_ERROR_MSGS" apply to the script, which is fine in this case. However, if there are some "conflicting" debug modes, I am not sure how to set the "precedence of debug_modes"? Also, I am not certain if my approach is good enough to Perlists and I hope I am getting my feet in the right direction. One biggest problem is that I now put if statements inside most of my subroutines for controlling their behavior under different modes. Is this okay? Is there a more elegant way? I know there must be a debug module from CPAN or elsewhere, but I want a real minimal solution that doesn't depend on any other module than the "default". And I cannot have any control on the environment where this script will be executed...

• Can HTML checkboxes be set to readonly?

  - by Electrons_Ahoy

  I thought they could be, but as I'm not putting my money where my mouth was (so to speak) setting the readonly attribute doesn't actually seem to do anything. I'd rather not use Disabled, since I want the checked check boxes to be submitted with the rest of the form, I just don't want the client to be able to change them under certain circumstances.

• Add effects to datagrid invalidate

  - by MooCow

  Is it possible to add an effect to a datagrid when I call invalidatelist to update the data? If it can be done, can the effects be selectively applied to only certain cells in the grid? The grid is showing an array with some nested array in it. I'm using an int counter to keep track of the nested array element position. When the counter is advanced, I tell the grid to update using invalidatelist.

• Is it possible to make the iPhone keyboard invisible / remove it without resigning first responder?

  - by Alex Gosselin

  I am looking for a way to show my own input view (a UITableView) to enter certain keywords in a UITextView faster than typing them, and also be able to type into this text view the normal way. My solution has a button that causes the keyboard to disappear, revealing the table view underneath it. Problem is I can't figure out how to make the keyboard go away without resigning first responder, and losing the cursor. Has anyone accomplished this before? Thanks for any help.

• SQL - Conditionally evaluate WHERE clauses

  - by Crimius

  I need to get a WHERE clause to only evaluate certain statements. something like: WHERE field_a = field_b AND (CASE WHEN <PARAM>type</PARAM> = 5 THEN {field_c = 1 OR field_c = 2} WHEN <PARAM>type</PARAM> = 6 THEN {field_c = 3 OR field_c = 4} ELSE field_c = <PARAM>type</PARAM> so that when the Param type = 5, it only checks if field_c = 1 or 2. Any thoughts?

• Drupal User Permissions, Only Allow Specific Users to Edit Specific Pages

  - by jordanstephens

  I know I can set up a role to allow user's to only edit their own pages, then go mark the appropriate pages to be authored by the appropriate user. But then I run into multiple users per page problems. Is there any way that you can explicitly only allow a user to edit certain (perhaps multiple) pages, while accounting for overlap in the case that more than one user may be allowed to edit the same page? Thank you

• How can I hide a work item field from some users in TFS 2008?

  - by muerte

  I'm customizing work item templates in TFS 2008 through the PowerTools and I'm wondering is it possible to hide a field (or it's value) for certain users? For example, let's say I open TFS to my clients so they can submit feature requests. I'd like them to see the work item created, to see the history, changes etc. but I'd like to keep some of the field private and for our internal use. Is it possible?

• What would you recommend for a undergraduate final year project?

  - by Thach Tran

  To narrow down the question, please suggest web-based topics only. To be honest, I'm struggling to find one for myself :) I'm doing Computer Science and looking for a web-based, individual project. A suitable topic would have a certain degree of novelty, so while you guys browsing the web everyday, what kind of things you expect but haven't come up before. Sorry for my lousy English :)
