In reply to Peter.

@Peter – hParent is supposed to be the handle to the container (typically a uipanel) that contains your control.

As to why MSCOMCTL is not available in your system, that’s probably because you’re using a new Windows version that does not have this control. After all, the post was originally written back in 2011, when Windows XP was king. You might find an alternative ActiveX control on your Windows, but my opinion is that ActiveX should be avoided in general – it’s an old and problematic technology. You’d be much better off using Java controls instead.

Hi Yair, big fan of your blog. Thank you for increasing the worlds productivity by a not insignificant margin.

On-topic then, I’m trying to learn from your example but I fear I’m missing something obvious. Why is hParent not defined in your example?
To troubleshoot it myself, I tried creating an ActiveX object in guide, but I can’t see MSCOMCTL in the list. (even after MSCOMCTL.OSX was successfully added to the registry in command prompt.)

It’s probably a bkac problem, but it has been a few years since your post, so I wonder if Windows or Matlab has changed and broken your example. I’m therefore not sure how much I should persist to get your example to work.

This is a very long and roundabout way to do something there’s already a simple solution for in MATLAB:

In your VBS code, have the line:

Wscript.Echo MyOutputVariables

Where “MyOutputVariables” is your desired output

Then call from matlab with dos:

[status,message] = dos('cscript myvbsfile.vbs');

Where myvbsfile.vbs is the name of your script. Message will contain the output you’re looking for.

voila!

cscript is an alternative to wscript (Windows default for VBS files) which will output the command to a console (vice a message box) – in this case, the MATLAB console since it was called from MATLAB.

I tried this in 2015a, but I’m sure it works in any version with the dos command and Windows version that supports cscript.

In reply to Ric. You could try to use Mex and interface via C++

I recently looked at RTD functionality in excel and realised it could be very interesting to port into matlab.
Making a bridge without making excel crash would give access to a number of services I would like to use.

Would ScriptControl be a good starting point? I also read about writing a wrapper in C# that would expose rtd functionality to COM and then it would be easy to interface.

Any other hack you can think of?
