Use EnumWindows/EnumChildWindows

what kind of handles -- all handles such as gdi objects, file handles, windows handles, etc. or just windows handles. jayender's suggestion only returns windows handles.

Take a look at this thread,

Good question! I'm looking for the value that the Task Manager displays when you check the handle count

Well, that count is for the whole system and not for a process.

However, to help starting let's open the list:

1. GetGuiResources - the count of handles to graphical user interface (GUI) objects in use by the specified process.
2. EnumProcessModules - retrieves a handle for each module in the specified process

NOTE: when the list will be completed, do not forget toa add the process (handle) itself. :D ;)

You can use Performance monitoring API's to get that,
See the Process objects Handle Count property,
