Javascript instantiate COM object?

[pithhelmet]

Hi everyone,

I have a IE web site that needs to use a series of DLL files
loaded on the client machine.

I know that an activeX can call the objects,
but we are talking about having javascript instantiate and use the
functions in the DLL.

This might be in the wrong forum - sorry if it is.

thanks
tony

Can JavaScript use the CreateObject command?

You'll get absolutely nowhere with an attitude like that. We're trying to help you, so cool it.

yes, you can, provided the object exists on the server if running from a webpage (unless it's a .HTA application, in which object on client is ok?).

Here's a syntax example:

myObj = new ActiveXObject("Word.Application");

then use it the same way as with VBScript. But remember methods must be called with () like myObj.myMethod(args); and don't forget the semicolon at the end.

You can also perform error/exception handling of the COM object by using a try/catch block in javascript on the object method in question, etc. like

try{
myObj.mymethod();
}catch(err){
//handle error here
}

I find this kind of COM error handling much more effective than when using VBScript to do the equivalent (which lacks the extra error handling features of VB).
