It takes a bit more than just turning on a couple of options.

You didn't really read the link I posted, did you?

Hello,

declare:

Private Declare Function MakeSound Lib "kernel32" (ByVal soundFrequency As Int32, ByVal soundDuration As Int32) As Int32

after that you can call for the MakeSound([frequency in hz],[duration in ms]) function and the computer will generate the tone trough its speakers.

i want to do something like this

Option Explicit
Option Base 1
Private Sub CommandButton1_Click()
Dim Sc(3) as integer
Dim Frequency=440
Dim Duration = 1000 ' in millisecond
Sc(1)=1
Sc(2)=1.125
Sc(3)=1.2

For i = 1 to 3
' some code is required to play the sine wave sound for above frequency and duration

next i

End

try this:

Option Explicit
Option Base 1

Public Class NameYourClass

Private Declare Function Beep Lib "kernel32" (ByVal soundFrequency As Int32, ByVal soundDuration As Int32) As Int32

Private Sub CommandButton1_Click()
Dim Sc(3) as integer
Dim Frequency as int32 = 440
Dim Duration as int32 = 1000 ' in millisecond
Sc(1)=1
Sc(2)=1.125
Sc(3)=1.2
 
For i = 1 to 3
Beep(Frequency, Duration)
next i
End sub
End Class

note: i just putted a class around it so you could see where to paste what.

hi nick
Actually i don't want to use the beep function but to generate the sine wave sound

isnt that just a very long beep? note that the kernel32 beep isnt the .net beep (the .net beep will give you the windows error 'klunk' while the kernel32 beep will generate a tone with the given amount of hertz during the given amount of milliseconds)

but now that i think about it, not sure how it works with the 'wave' part..
did i quick google for ya and found this[^] its in vb6 a bit old...and not directly what you need. but it might be able to help you (or so i think)

Hello
for making a game you need to use a 3d engine.
contact www.3dstate.com
it has a wonderful game engine.

Get the source code, make your change, compile.

There are only 10 types of people in the world, those who understand binary and those who don't.

What do you mean by "edit"?

And don't post the same question twice.

Unless you have the source code you cannot edit it.

Richard MacCutchan23-Jun-12 2:20

23-Jun-12 2:20

You cannot do this without the source code. It does not matter how simple the game is, if you only have the executable then you need to decompile it and rebuild from the decompiled source.

Midnight Ahri24-Jun-12 16:07

but i think decompile and edit an exe is not that easy, it's already an assembly code, am i wrong? D'Oh! | :doh:

Richard MacCutchan24-Jun-12 21:58

24-Jun-12 21:58

You are correct, it is extremely difficult, and probably not worth the effort. The chances of you being able to hack the game are quite low.

Midnight Ahri24-Jun-12 22:04

so every game hacker are editing assembly code?
mother of code OMG | :OMG:

by the way, thank you for the information. Smile | :)

Some are probably editing direct machine code; but there are better ways to use your talents in this world.

I made a control which has a button on it.
But I need to change the text of it when it is clicked.

this is what I have tried but it didn't work:

If Button1.Text = "1" then
 Button1.Text = "0"
Elseif Button1.Text = "0" then
 Button1.Text = "1"
End if

I put that code on a button_click event in a UserControl that I made.
It is supposed to work as a boolean. eg if the value is 1 then it should change it to 0
else if the value is 0 it should change it to 1.
