Hello,
I recently found this while messing around on a free day in my
computer programming class. It's a simple program that loops backcolor
hex values infinitely in a simple goto loop. When executed it causes the
machine to instantly jump to 100% CPU usage. This might be from the
program looping the backcolors. I'm not sure though.
This is what the source looks like:
Private Sub Form_Load()
GoTo g:
g:
frmMain.BackColor = &HEBBD78
frmMain.BackColor = &HFF&
frmMain.BackColor = &HFFFF&
frmMain.BackColor = &HFF00FF
frmMain.BackColor = &HC0C0FF
GoTo g:
End Sub
This has been tested only on Windows 2000 Professional machines.
Have a good one,
