Today’s Little Program prints the name and position of the focused item on the desktop. Remember, Little Programs do little to no error checking. <\/p>\n

After initializing COM and getting the desktop folder view, we get the underlying
IShellFolder<\/code> because we’re going to need it in order to interpret the pidls that come out later. <\/p>\nWe ask the view for the index of the focused item. If it can’t cough one up, then we apologize and exit. <\/p>\n
Otherwise, we use that index to get the corresponding pidl and then ask the folder to convert it into a normal name (which is the name shown under the icon) and a parsing name (which for files is the full path name). <\/p>\n
Finally, we ask for the item position. <\/p>\n
There you have it, a little program that identifies the current focused item on the desktop. <\/p>\n","protected":false},"excerpt":{"rendered":"
