message at the refresh rate.

hi, my friend asked me if i could make a program for him that will blink a message at the refresh rate of the computer, I.E. imperseptabel, he is wondering if he could tech himself vocabulary words with it.

all i want is to display text, nothing fancy like shapes or pictures, but it can't have any flicker (that would be incredibly anoying) any help of with this would be greatly apprecieated, thanks

Do you mean at the refresh rate of the monitor? eg 85 hertz or whatever?

Wouldn't you first have to check the refresh rate of the monitor? As far as I know, this changes from monitor to monitor, so that would be your first step.

yeah, sorry, that is what i ment, but i didn't really explain my self verry well, i just want somthing that works as fast as possable, i don't really care about the refresh rate of the moniter.

P.S. i was woundring, would this appear on the screen? or would it just flip through th code to fast?

VB Code:

lable1.visible = true
lable1.visible = false

when i run it on a computer with an old moniter, i get some flicker.
(the funny thing about this program is that if it is working you won't know it :bigyello: )

Try this instead:

VB Code:

Private Sub Form_Activate()
 
     AutoRedraw = True
 
     Do
 
          DoEvents
 
          If Label1.Visible = True Then
 
               Label1.Visible = False
 
          Else
 
               Label1.Visible = True
 
          End If
 
     Loop
 
End Sub

You need to access some hardware port that gives you a sync signal. You can do it in DirectX
