Hi folks,

I'm writing a shell jscript for WSH and want to know if it's possible to extract the text in child controls from other Windows applications that are running. Some examples would be obtaining the text from a button in a dialog box, reading the text values from the nodes in a treeview or combobox, etc.

Enumerating existing processes is the first step, which i've done, now i want to dig down into those processes...

Ideas?

Not with WSH, however using the FindWindow and FindWindowEX API functions you can find child windows and read the text using GetWindowText etc.

Can you give me a little more info on that API? I've never heard of it before and I'm not sure where to even begin reading about it.

It's all on MSDN!

• FindWindowEx to retrieve the handle you're looking for.
  
• GetWindowText to get the text associated with that handle.

You need to use Interop.Call and Interop.Allocate to work with these Win32 API functions, which might be scary at first sight. Have a look at some more complex scripts and see how those use the Win32 API.

what are you doing it for? there's probably a better way

thnx for the good advice Matti - could you point me at some example scripts that use Interop?

Is Interop part of the MPL infrastructure or is it something that can be used in JScript's in general?

The Win32 API can be used in a lot of programming languages however JScript and VBScript do not have access to it. Interop calling in Plus! Scripting is provided by Messenger Plus! Scripting Engine without it you couldn't do it unless you created an ActiveX Object.

Cheers.

That's awesome info, Matty! Thanks for your excellent input.
