OK, fine, however it will still crash.

It crashes on "Initialise parse interface..." which is sequentially somewhat before where it attemps to do "Test script...".

I tested it, and it crashes as I expected. I would expect BTW that on a syntax error I would get a nice error message, after all syntax errors would be common enough, and should not cause "catastrophic failure" or an access violation.

Meanwhile, perhaps you can interpret the "message box" idea into Tcl for me. How would I create a COM object (like in the examples in the other languages) or put up a message box?

You didn't mention what version of tcom you are using. The Tcl Active
Script engine in the tcom distribution is still in an experimental
state. The tcom-3.9b8.zip beta version from the
http://www.vex.net/~cthuang/tcom/ Web site includes an update to the
Tcl Active Script engine.

The test program doesn't crash, however you haven't replied to my earlier question about how to do, say, a message box, so all I can say is that it doesn't crash, not that it does anything very spectacular.

However MUSHclient still does crash, bearing in mind that the exact same code works fine for the other 4 scripting languages.

I think it is a bit obscure to have to download tcl from ActiveState and then add in bits and pieces from other sites, I doubt everyone will want to do that.

I'll take another look in a few days.

Here you go:
set WshShell [tcom::ref createobject WScript.Shell]
$WshShell popup "Hello, world" 0 "test"

I'm gonna bump this thread, because there appear to be new versions of TCom since a year ago:

http://www.vex.net/~cthuang/tcom/

I think it's long enough that mentioning it again wouldn't be that annoying ;)

So have you tried TCL with the latest MUSHclient? TCL is an option in the scripts drop-down menu, so you could try it and let me know how it goes.

I installed TCOM and registered TclScript. When I try it with a script with just a comment, no actions (the most bug-proof test of all ;), I get

"Error -2147467263 occurred when getting script engine dispatch pointer:

Not implemented"

Sounds like it is not fully implemented. The exact same code works for other languages, here is the part in question ...


// set state to started

  if (ShowError (m_IActiveScript->SetScriptState (SCRIPTSTATE_STARTED),
    "starting script engine"))
    return true;

// connect outbound objects (ie. world)

  if (ShowError (m_IActiveScript->SetScriptState (SCRIPTSTATE_CONNECTED),
    "connecting script engine"))
    return true;

// get script engine dispatch pointer

  if (ShowError (m_IActiveScript->GetScriptDispatch (0, &m_pDispatch),
    "getting script engine dispatch pointer"))
    return true;


It got through everything (starting, connecting) until getting the dispatch pointer (which is needed to call scripts). That was the last thing it had to do. The same code works for Perl, Python, VBscript, JScript.

Sounds like TCL is not ready yet. :)

Do you get the same behavior when you test it yourself? Or did you just put it in and leave me to try it without any tests? ;)

I left it for you. :)

I am reluctant to keep installing all these additional script engines. Do you think I'll get different results?

Configuring Tcl seems to be a pain, I'm learning COM stuff and I might try it myself and tell you how if I figure it out. Feel free to take it out for now ;)

If you mean other languages, I think it's pretty reliable on average. Though there aren't that many commonly used languages that you haven't already done <g>
