c# hax0ring

[ #3809 ]
We've decided to go down the route of C#/perl for future projects, mainly due to lack of GUI goodness for perl. I've been prodding slowly at C#, dipping my toes in the water.

One thing that stumped me for about an hour today is 'optional' parameters. I was trying to call the Navigate method for the web browser control. In VB I would have ignored the optional parameters as they are optional (cunning eh?). C# doesn't think this is a good idea, and after a little digging I found you need to do:

object o = null;
webbrowser.Navigate(url, ref o, ref o, ref o, ref o);

Which looks plain dumb. Oh well.

I should also motivate myself to file some Komodo bug reports, but I feel these should have been stomped on before release. Ho Hum.

  • The fact that you're using C# tells me that you're using MS Windows and possibly .NET. If so, you have a few good options (besides Komodo).

    Visual Perl. If you're using the Visual Studio software, Visual Perl is very nice. You can get it at I think it's about $100.

    PerlBuilder at Pretty good, aimed somewhat at CGI programmers. About $150 for the standard version, $250 for the pro version.

    Your free option is OpenIDE []. Better than Komodo by a long shot, but then it

    • We paid out the $495 for ASPN Perl []. I'm pretty pleased with it so far. I've only really been using Komodo as Visual Studio .NET still scares me :)
    • I'm downloading (very slowly) OpenIDE right now. It looks very cool, and exactly what I've been looking for running on Windoze. Over the last week I've been toying w/ Project Builder on MacOS X, and it rocks! It has all the features you'd expect out of an editor/IDE, and then some. So anything that comes close to PB is a good thing. Thanks for the link.

  • Have you taken a look at possibilities like wxPerl [], Tk, Gtk or Win32::GUI???

    There is enough GUI goodness for Perl!

    • I have. Tk is pretty much ruled out becuase it doesn't look like a windows application. This might sound harsh, but it makes sense for us. I have experimented with Tk, I sent a small app to a client and he was frustrated by the file open dialog as it had a 'home' button that didn't work and you couldn't choose a disk/networked drive.

      wxPerl looks promising but the lack of documentation is a factor. I'm also not sure if I'm that keen on creating forms without a GUI. The Visual Studio .NET GUI is very slick

      • I agree completely on the Tk story. wxPerl indeed lacks documentation (working on it Sir!), but what do you mean by creating forms without a GUI? wxPerl is all about GUI....

      • I sent a small app to a client and he was frustrated by the file open dialog as it had a 'home' button that didn't work and you couldn't choose a disk/networked drive

        You need Tk::DirSelect [] (follow the link to downloads and screenshots)

        • I actually found that today, but couldn't get the code to work. I wanted a widget that could select a directory. Eventually I found some code that got a Tk::DirTree and worked ok (linked towards the bottom of that page). The main problem I have is that Tk programs look icky. Tk::DirSelect looks really amateur compared to today's graduated fills, recessed buttons etc on win32.
