I read a lot of posts with people telling they are getting a surtain frame rate with there project.
My question is. How do you write a bullet proof piece of code to get your frame rate?
I'm new to game programming, so making a mistake in doing this could turn out possitive or negative. I just wanna be sure....

Well, on the simplest level, having definite FPS comes from a Sleep loop that will wait until time has passed.
You'd usually use the GetTickCount to get a millisecond time and then Sleep to wait.

Then:

Const MaxFPS As Integer = 10
Dim L As Long, L2 As Long
Do
    L = GetTickCount
    Call AVeryLongAndComplexProcedureThatIsTheBulkOfThisApp
    L2 = GetTickCount
    If L2 - L <= 1000 \ MaxFPS Then
        Sleep ((1000 \ MaxFPS) - (L2 - L))
    End If
Loop Until bEscape

If I read this write than would say
you take the tick count before the game actions
and afterwards and you have the result
tickcount 1000 = 1 sec ? nevermind... those are milli secs
I wouldn't need the sleep function as I don't wanna be limiting the speeds right now
Just want to know the speed how many frames are done per second without limitation

To find your FPS:

L = GetTickCount 
Call AHotMess  'your game code
L2 = GetTickCount
FPS = 1000 / (L2 - L)

I normally just use a timer set to 1000 ms with a global (or module level) long counter called FPS.

Private FPS as Long

Main Code:

Do
     'Main Loop code
     ....
     FPS = FPS + 1  'increment the frame counter
Loop While Not bDone

Timer code:

Private Sub tmrFPS_Timer()
me.Caption = "FPS: " & FPS
FPS = 0
End Sub

It's simple, accurate, and gets the job done.

When choosing between the two methods presented, bear in mind:

Iceplugs method calculates the FPS for each individual frame. This is great but could lead to a fair amount of fluctuation. My way averages out the cycles over 1 second.

Iceplug can get FPS in fractional increments. My way is whole frames only.

Iceplug doesn't show how you display the FPS but you probably should NOT update the screen every frame....any kind of screen refreshing takes a lot of time and will decrease your frame rate. My way updates the screen once per second, not once per frame.

Iceplugs way is pure code (well, there is an API in there...). My way requires a timer control.

thnxz works great

Im lost with this..ehhh does anyone know a where i can find a tutorial for FPS, or better yet can someone explain (In simplest form!!) how i can write the code.

I think Billsoo's reply is self explaining
not much too it if you use his method.
