This is only a School project, and I like to know if this is possible in anyway. I am not trying to overwrite any other applications. However, I might take a wrong approach for this project. :( If not possible, I may need to reconsider my project. :) Thanks for the reply All. Khanh.p

Hello All, I am working on a school project; using c# to create a windows form application to modify Window's mouse cursor. I have tried many attempts using cursor class that MSDN provided. However, I was not successfully done what I'd like to do for this project. I'd like to know if there is anyway that I can change the arrow cursor to my custom cursor out side the application form (When the application actively in the foreground or sit in the system tray)? I only able to change the cursor when the mouse is actively within the application form, but when I move the mouse to the desktop (outside the application form) it would change to a default window cursors. Please let me know if I can change the window's mouse cursor permanently once my code is active or any alternative i.e.: change the registry keys to make this happen. Many thanks, Khanh.p
