There is a least one typo in the code:

Code: Select all

ProcedureDLL Beep(freq.l, time.l)
  Protected n.f = (freq/1000)*100
  setLEDfcol(0, RGB(n.f*2.5, 250-(n.f*2.5), 0))
  setLEDstate(0, n.f)
  Beep_(freq, time)  ; <==- this is a call to an API routine (this isn't a recursive procedure)
EndProcedure

This may or may not be related to the problem you are experiencing. If the program make it to the point of calling Beep() it will loop forever without really doing anything before the stack fills up.

yes it has nothing to do with the problem, It said that the Image was not Initialized.

I believed I ran it before with no problem. What happened ?

StartDrawing(ImageOutput(led()\imageid)) : "THIS IS WHERE THE PROBLEM IS"

If the image wasn't successfully created before trying to draw on it you will get this message, it is self-explanatory.

To find out more, add these lines before the line where the error occurs:

Code: Select all

If led()\imageid = #Null
  MessageRequester("Fatal Error", "Image can't be created (w:" + Str(led()\width) + ", h:" + Str(led()\height) + ")")
  End
EndIf

If the message requester appears it usually means there isn't enough memory ... though there may also be other reasons.

I have the same problem.
The result of CreateImage is not null, so this means the creation has succeed.
But I still have the "The specified #image is not initialized" when compiling.

Same here like specified above.

Does the code get past drawing to the image if the procedures are changed from ProcedureDLL to Procedure?

Nope...
