i need to no how to make a tone like 1500Hz to be outputed for a certain length when the left mouse button is clicked and a shorter length when the right button is pressed. this is to make the dots and dashes for CW (MOROSE CODE).

Copy this code in your form

Option Explicit

Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim tone
Select Case Button
Case 1
tone = Beep(1500, 250)
Case 2
tone = Beep(1500, 500)
End Select
End Sub


copy this code in a module
Public Declare Function Beep Lib "kernel32" (ByVal dwFreq As Long, ByVal dwDuration As Long) As Long


For your information:
This function will be good with all windows versions exeptionally with Win 95 or 98

thank you for you help in this matter but i have to make one that generates the tones as you put them into the keyboard example

"k" would be "long, short, long" or "-.-"
so on and so on


i have the code for a program that does this but it is written in basic and i want to have it in VB

In the Keypress event just add a Select Case statement:

Private Sub Text1_KeyPress(KeyAscii As Integer)
Select Case KeyAscii
Case 97 'a
call short
call quiet
call longer
call quiet
Case 98 'b
call longer
call quiet
call short
call quiet
call short
call quiet
call short
call quiet
Case 99 'c
' etc etc

Case Else
KeyAscii = 0
Beep
End Select
End Sub

Sub Short
tone = Beep(1500, 250)
End Sub

Sub Longer
tone = Beep(1500, 500)
End Sub

Sub Quiet
' use sleep api or whatever for 250 msec wait
End sub

This isn't finished code! But it should give you the idea

hmmm and the second i posted i googled!!


there is no pattern.... or is there????

i also note the lines

"If the duration of a dot is taken to be one unit then that of a dash is three units. The space between the components of one character is one unit, between characters is three units and between words seven units. To indicate that a mistake has been made and for the receiver to delete the last word send ........ (eight dots)."

hmmm...!

good luck!

jenkies... i was sooo close, i just changed to using a lookup table and it works... hoorah!!

its not perfect (well if it is ill be impressed cos i only done about 3 minutes testing on it!!! [lol])

Code: 
Private Declare Function Beep Lib "kernel32" ( _
    ByVal dwFreq As Long, _
    ByVal dwDuration As Long _
) As Long

Private Declare Sub Sleep Lib "kernel32" ( _
    ByVal dwMilliseconds As Long _

Dim LookUp(45) As String

couple of quick revisions!

in the delete section of the code:-

ElseIf KeyAscii = 8 Then
Text1 = Left$(Text1, InStrRev(Text1, &quot; &quot;) + 1)
Text1.SelStart = Len(Text1)
BeepMe LookUp(45)

i forgot to delete the whole word and was just deleting the last character

and in the beepme sub:-

'wait 3 units after character
Sleep UNIT * 2

because we already waited 1 unit after the last character!

hope it helps.. good luck!
