Prerequisites:

• I am trying to create a mouse hiding application that hides a custom mouse from the screen after a certain time.
• I tried many things, and using SetCursor only hides the mouse from the current application, mine should be able to sit the tray (for example) and still function.
• I think I found a solution using SetSystemCursor, except for one problem.

MY PROBLEM:

• I need to catch any kind of mouse cursor and replace the same mouse pointer.
• When replacing the mouse, I need to specify the identifier of the type of mouse that I would like to replace with the mouse that the descriptor refers to, but none of the functions that I use provide me with the copied mouse identifier (or type).

MY QUESTION:

• , 0,0, ? (Unhiding ).
• 0,0 OCR_NORMAL mouse? ( .)
• , /id , ?
