WinSpy Alternatives
WinSpy is described as 'tool for retrieving details of an open window in the Windows desktop environment. It appears that it has superceded WinSpy++' and is an app in the os & utilities category. There are five alternatives to WinSpy for Windows and.NET Framework. The best alternative is Window Detective, which is both free and Open Source. Other great apps like WinSpy are WinSpy++, WinID, Winspector Spy and XWinspector.
Window Detective is a programmer's tool used to "spy" on an application's windows and allows you to view and even modify some of its properties.
WinID is controls & windows identification utility that is both powerful and compact. Its main purpose is to give an easy way to retrieve information about Microsoft Windows controls visually right off the screen.
Have you ever used Spy++ that comes with MSVC? If you have then you know what Winspector is - but take out all of the annoyances of Spy++ and add in a big bag of handy tweaks and features.
