Create ActiveX object from CLSID

[Matt Lind]

Anybody know a quick way of taking a CLSID provided as a string and creating an ActiveX object it represents?  Preferrably in JScript.

 

thanks.

One way I know, is to read the ProgID from the registry:

var shellObj = new ActiveXObject("WScript.Shell");
var clsid = "F5078F32-C551-11D3-89B9-0000F81FE221";
var progid =
shellObj.RegRead("HKEY_CLASSES_ROOT\\CLSID\\{"+clsid+"}\\ProgID\\");
var xmlDoc = new ActiveXObject(progid);

We have a wrapper in XSIFactory to create activeX objects from a prog ID (i.e. string):

XSIFactory.CreateActiveXObject

GUID string is also supported.

This works. Could you point me to some documentation where you found
how to do this?

So far I've used 'find' in regedit to locate the ActiveX control and the
string needed to generate it using 'new ActiveXObject()', but would be
nice if I could do the reverse lookup automatically and ditch CLSIDs
altogether.

Thank you.

I get a string returned from some of the APIs I'm using like:

"<object {clsid:xxxx-xxxx-xxx-xxx-xxx}, attributeName="", ....>

I need to convert the CLSID into the ActiveX object. I have tried:

var oControl = XSIFactory.CreateActiveXObject(
"clsid:xxxx-xxxx-xxxx" );
- and -
var oControl = XSIFactory.CreateActiveXObject( "xxxx-xxxx-xxxx"
);

LogMessage( "Class: " + Application.ClassName( oControl ) );

but the returned control doesn't play nice with Application.ClassName().
No exceptions thrown, but nothing is returned either. So I have no idea
what was returned.

Did you try the the guid string in braces? That's the standard notation. {abdb-....ab}

@Matt:

It works when you remove the "clsid:"-part from the string, but leave
the brackets:

var oControl = XSIFactory.CreateActiveXObject("{xxxx-xxxx-xxxx}");

WScript.Shell is part of Windows Scripting Host and can be used to
access the Windows shell. It also has some basic methods to deal with
the registry.
