问题 I'm trying to check if javaw.exe has focus, then execute certain code if it does. Previously I had code which would look for the process ID of javaw.exe, then compare it to the process which currently had focus, which worked for awhile, but then I noticed when I had more than one javaw.exe process running, it would only work on one of those processes, while I need it to work when any javaw.exe process has focus. Is there any way to do this? 回答1: You can determine this quite easily using the

问题 Activewindow.UsableWidth gives me the width of the screen with the Vertical Scroll Bar's width included. Is there a way I can calculate the width of the Scroll Bar? I measured it by having one shape be UsableWidth and the other shape be what I actually can see, and the difference is the width of the Scroll Bar. I'm wondering if there's a way to automate it so it can be used by a user with a higher or lower resolution, and therefore smaller or larger Scroll Bar. Thank you! 回答1: If you are
