    Use this thread to say anything about programming.
    Including questions, suggestions, small programs, etc.

    I just compiled a C++ program that loads a Java VM (Sable's) and runs a Hello World class in it.

    And it even worked.

    Also, I have a SVN account for KDE4. Beat that.

    ...Huh, am I supposed to beat that?

    Anyone here tried out the Ruby language? Anyone written anything with it?

    Nope. And here, we only use the java.net.* package to nuke each other's comp.

    This may be also a place to show your Piet programs.

    I once looked at some Ruby code, but never written anything in it.

    Hey Amarth, quick Perl question. Suppose I wanted an IRC bot to reset itself... that is, disconnect totally, load all settings from scratch, and reconnect? Without closing it down, modifying the settings, and restarting it, obviously. ;P

    I don't know... Custom code, I think. Provide subroutines for those three things and they're easily reused.

    No, really?

    I know how to disconnect... that's fairly easy. However, when I do that, it kind of stops running. I want it to reconnect with a fresh batch of settings (so perhaps reconnect isn't the right term ).

    Well, the POE kernel will quit if you unregister for all events. Don't unregister the events if you don't want it to quit. Or perhaps unregistering and re-registering them in one quick pass (ie, in the same subroutine) also doesn't quit the run() method, I don't know.

    Unless you quit by sending POCOIRC_SHUTDOWN, that seems to be some new way of doing it. Then don't send that and disconnect manually.

    Another way would be to set up a loop that only quits when some flag 'trulyreallyabsolutelypositivelywantstoquit' evaluates to true. While the flag is false, register for all events, load settings and start the bot.

    Anyway, I don't know what your code is all about, I don't know how you read and write settings, how you quit, how you connect, ... in your code. For what I know, we might be talking about different things here ('I want to reconnect, but reconnect is not the right word' - am I supposed to understand you? ). Don't expect me to read your mind.

    I was SO close to saying "No, you should beat it." when I saw this...

    Perfect, that's what I should do.

    I could've sworn I've shown you MageBot's code at some point or another. Hell, you half-wrote most of it.

    I'm trying to make a Piet Interpreter. But for now, I have no idea on how to get the hue and darkness differences between two colours.

    Amarth 10 years ago
    Try Wikipedia and more Wikipedia.

    E_net4 10 years ago
    Wii thanks.
    I hope you'll see a Piet Interpreter soon.

    It's all 4chan related.

    Because serious posts require serious replies.

    Anyways its all based in perl and compiled, etc etc all the jumbo of creating your own reference.

    I'm guessing we're supposed to compile it ourselves. Oh, goodie.
    #

    Is there a way to compile some code ourselves? As in, an EXE file?

    isnt perl a script you can run rather than compiling it... ??? meh im not sure myself anyway

    Perl code is compiled, then run. The only difference is that the compiled version is generally not saved.

    By "Generally not saved", do you mean that there's no way to do it whatsoever, or that nobody wants to because the language compiles fast enough to make transferring the code more economical?

    I'd say the latter.

    Pretty much, yeah. Plain text code is easier to deal with. Perl compiles & runs it fairly quickly, so it's more convenient to keep everything in code form. You could, of course, compile Perl code into an executable... but unless you're making a program you intend to distribute to people who don't have cygwin, I don't see the point.
    #

    Also note that compiled = processor architecture+OS dependant. Thus extremely unportable.

    You might all use Windows + x86, but the FOSS world doesn't really care too much about Windows.

    My Visual Basic code to convert a Hex value into a Dec value isn't working. Could someone check?
    txtHex holds the Hexadecimal value.
    Private Hexs() As Integer

    Private Sub cmdConvert_Click()
    Dim Final As Long
    Dim i As Long
    Dim lengh As Long
    lengh = Len(txtHex.Text)
    ReDim Hexs(lengh) As Integer
    For i = 1 To lengh
    If Not IsNumeric(Mid(txtHex.Text, i, 1)) Then
    Select Case Mid(txtHex.Text, i, 1)
    Case "A": Hexs(lengh - i) = 10
    Case "B": Hexs(lengh - i) = 11
    Case "C": Hexs(lengh - i) = 12
    Case "D": Hexs(lengh - i) = 13
    Case "E": Hexs(lengh - i) = 14
    Case "F": Hexs(lengh - i) = 15
    End Select
    Else
    Hexs(lengh - i) = Int(Mid(txtHex.Text, i, 1))
    End If
    Next i
    Final = 0
    For i = 1 To lengh
    Final = Final + Hexs(i) * 16 ^ (lengh - i)
    Next i
    txtDec.Text = Final
    End Sub
    #

    Yay, about everything I hate about VB in one post. Anyway, one solution that works for me is
        Private Sub cmdConvert_Click()
    Dim Final As Long
    Dim i As Long
    Dim lengh As Long
    lengh = Len(txtHex.Text)
    Dim Hexs(lengh) As Integer
    For i = 1 To lengh
    If Not IsNumeric(Mid(txtHex.Text, i, 1)) Then
    Select Case Mid(txtHex.Text, i, 1)
    Case "A" : Hexs(i) = 10
    Case "B" : Hexs(i) = 11
    Case "C" : Hexs(i) = 12
    Case "D" : Hexs(i) = 13
    Case "E" : Hexs(i) = 14
    Case "F" : Hexs(i) = 15
    End Select
    Else
    Hexs(i) = Int(Mid(txtHex.Text, i, 1))
    End If
    Next i
    Final = 0
    For i = 1 To lengh
    Final = Final + Hexs(i) * 16 ^ (lengh - i)
    Next i
    txtDec.Text = Final
    End Sub
    though you might need to change it to your local VB dialect (mine is VB.Net 2005)

    A better solution might be
        Private Sub cmdConvert_Click()
    txtDec.Text = CLng("&H" & txtHex.Text)
    End Sub

    I am now reviving this thread to tell you about a test I did.
    I created a Visual Basic program to tell me the speed of pixel drawing using 3 drawing methods: PSet, BitBlt and StretchBlt

    PSet is a VB function that draws a pixel in a certain position with a certain colour.
    BitBlt is a Windows API function that draws an area of a source into another.
    StretchBlt is similar to BitBlt, as it's capable of setting different resolutions from the source's resolution.

    I'll tell you more about it later, I'm in a rush to school. <!-- m --><a class="postlink" href="http://www.esnips.com/doc/1848ed42-6143-4e24-a8b0-1718541e3ec2/Drawing-Speed">http://www.esnips.com/doc/1848ed42-6143 ... wing-Speed</a><!-- m -->
