• Why not install Msvcr71.dll into system32?

  - by hillu

  While looking for an authoritative source for the missing Msvcr71.dll that is needed by a few old applications, I stumbled across the MSDN article Redistribution of the shared C runtime component in Visual C++. The advice given to developers is to drop the DLL into the application's directory instead of system32 since DLLs in this directory are considered before the system paths. What can/will go wrong if I (as an administrator, not a developer) decide to take the lazy path and install Msvcr71.dll (and Msvcp71.dll while I'm at it) into the system32 directory (of 32 bit Windows XP or Windows 7 systems) instead of putting a copy in each application's directory? Is there another good solution to provide the applications with the needed DLLs that doesn't involve copying stuff to the application directories?

Is there another good solution to provide the applications with the needed DLLs that doesn't involve copying stuff to the application directories? added after first answers: I understand that incompatible API changes may have been made to the mentioned DLLs, but pretty much every mention of incompatibilities I have found using Google had to do with games or video codecs. Right now, I expect that the risk of breakage is pretty small. Am I missing something?

• In Perl, how can a subroutine get a coderef that points to itself?

  - by hillu

  For learning purposes, I am toying around with the idea of building event-driven programs in Perl and noticed that it might be nice if a subroutine that was registered as an event handler could, on failure, just schedule another call to itself for a later time. So far, I have come up with something like this: my $cb; my $try = 3; $cb = sub { my $rc = do_stuff(); if (!$rc && --$try) { schedule_event($cb, 10); # schedule $cb to be called in 10 seconds } else { do_other_stuff; } }; schedule_event($cb, 0); # schedule initial call to $cb to be performed ASAP Is there a way that code inside the sub can access the coderef to that sub so I could do without using an extra variable? I'd like to schedule the initial call like this. schedule_event( sub { ... }, 0); I first thought of using caller(0)[3], but this only gives me a function name, (__ANON__ if there's no name), not a code reference that has a pad attached to it.

• Can a program that controls IE detect if a HTTP 30x code is encountered?

  - by hillu

  I am trying to control an InternetExplorer.Application via the COM interface, using Perl, Win32::OLE, and information from MSDN. My goal is to get as good an idea as possible about what IE is doing. (Related to this question.) IE uses events to notify my program when it has finished various stages of processing a certain URL (NavigateComplete2, DownloadComplete DocumentComplete). It can also tell my program about various errors it encounters (NavigateError2). I consider that part of my problem solved well enough. I would also like to be able to reliably detect if IE is redirected by the server. Primarily, I'm concerned about HTTP 30x status codes. Is there a way to do this, either with COM automation or via another route?

• What are the most interesting/useful new things in Perl 5.12?

  - by hillu

  I remember quickly adopting given .. when, say, //, and the smart matching operator when Perl 5.10 came around. What do you consider the most useful fixes and features introduced with Perl 5.12.0?
