Maybe I've been terribly "thick" about this, and if I have been, please forgive. However, I just figured something out and thought I might share it. I was noticing to-day in my Programs menu on my Win2K box that certain shortcuts display tooltip text indicating the location of the file, while others, like Excel said things like: "Perform calculations, analyze information, and manage lists in spreadsheets or Web pages by using Microsoft Excel."
I wondered what the difference was and found it. Links showing the location of the target file, have no entry in the Comments area. Those that do have the text like the above. What confused me is that there's another entry (on the General tab of the Properties dialog) that says Description.
After playing around with both my Lnkfiles.dll and the WScript.Shell's Shortcut object, I found that setting the "Description" (either through the DLL call or the object property) actually modifies the information in the Comments area and therefore can produce tooltips like the above.
