SendMessage in VBA

[prajul89]

I have took some VBA Codes from the Internet.
Its very complicated for me to know what exactly it is.

It has this line in between:

SendMessage GetDesktopWindow, WM_SETREDRAW, ByVal 0, 0&

I don't know what this line exactly does, But this line hangs my whole computer. Then the only way out is restarting the computer.

The codes also have Application.EnableCancelKey statement but have studied what it does and don't think it is a problem.

That code disables the screen redraw for your computer (hence it appears to hang). That's what you get for playing with API code you don't understand...
