I use on Microsoft Visual Basic 6:
Msgbox "Windows died and forgot to die because it died..",vbcritical,"Death finds us all
"
Then it should come up ur text.
Else if you want it to flood it,
Make a timer
Set interval to 1 (in properties)
Go to the timer's code and type msgbox "Text here",vb(Type), "Title Here"
Run the program
It will keep saying your message, however its not the bomb virus, it wont pile up, it will just make another after you click okay.
And the microsoft dos emergency shutdown
Go to run:
Type Shutdown -s -t 9000 -c "(message here)
To get rid of it, type in run, Shutdown -a
To get it into a file:
Go to notepad
type Type Shutdown -s -t 9000 -c "(message here)
Save as shutdown.bat, or something else of your preference
And there!, your own trap!
