in reply to Perl, Visual Studios, and Source Safe

Microsoft Visual SourceSafe does have an OLE module (certainly as of v6.0c) - you may have to specify you want to install it when you install Sourcesafe, I can't remember.

You then need to read up on Win32::OLE, and the difficult to find VSS automation documentation.

Following this, you'll need something like this to load the VSS library:

my $vss = Win32::OLE->new('SourceSafe.0') || die "Can't create VSS obj +ect\n"; $vss->Open($vssINI, $vssUser, $vssPass); die "Error Opening VSS db: " . Win32::OLE->LastError() if Win32::OLE-> +LastError() != 0;

(where $vssINI is the full path and filename of the INI file of the SourceSafe database you want to open.)

Subsequently, you can use the various objects and methods in the VSS docs to manipulate VSS resources. The VSS OLE interface isn't the most pleasant to work with, but it does work (mostly)...

[Corion]: ambrus: Yeah - I don't think the deep source dive will be necessary if things are implemented as simple as they could be :)) And hopefully I won't need (more) timely object destruction. I can update the screen at 60Hz and hopefully even do HTTP ...
[Corion]: ... transfers in the background. Now that I think about it, this maybe even means that I can run the OpenGL filters on Youtube input :)
[ambrus]: Corion: I mentioned that the unix event loop of Prima always wakes up at least once every 0.2 seconds. Have you found out whether the win32 event loop of Prima does that too?
[Corion]: ambrus: Hmm - I would assume that the onDestroy message is sent from the destructor and doesn't go through the messageloop, but maybe it is sent when a window gets destroyed but all components are still alive...
[ambrus]: Corion: partly deep source dive, partly just conservative coding even if it adds an overhead.
[Corion]: ambrus: Hmm - no, I haven't looked at wakeup intervals ... I wonder why it should want to wakeup periodically because it gets a lot of messages from the Windows message loop (on Windows obviously)
[ambrus]: (Alternately a deep source dive and then rewrite that event loop to make it better, and then as a bonus you get an idle method.)
[ambrus]: The 0.2 seconds wakeup is likely a workaround for some bug, but I can't guess what bug that is.
[ambrus]: It's been there since Prima 1.00 iirc
[Corion]: Hmmm... Weird. Maybe it needs that for doing its timers or something. Still weird.
