How can I extract data from a 3rd party application's UI controls?

Solution 1:

Sounds a lot like NirSoft's SysExporter:

SysExporter utility allows you to grab the data stored in standard list-views, tree-views, list boxes, combo boxes, text-boxes, and WebBrowser/HTML controls from almost any application running on your system, and export it to text, HTML or XML file.

Solution 2:

I just downloaded Count Characters v4.1 for 64 bit and it is working on Win 7 64 bit. It worked even to copy text from a listview inside a QT app !

Just my 2 cents so you guys know this tool is still working...
