Generate A Tone In .net?
Nov 20, 2009
I want to build a kind of a tone generator to tune my Ukulele (NERD allert, sorry for that).I know there are enough tone generators available but since a Ukulele has only 4 strings and not in the same order and tone as a regular guitar, they won't help me. My objective; to build a small VB.NET form with four buttons and every button will generate a specific tone.I've already tried Console.Beep etc [URL] but all I hear; no beep.As seen on the page at this link: QuoteThe Beep method is not supported on the 64-bit editions of Windows Vista and Windows XP.As far as I know, I'm not running a 64-bit Windows Vista, however, I'm running on a 64-bit processor.
I've tried Google (one of my best friends, but we seem te be in a separation?) but all I can find are examples in C# (since it is about music, C# is a regular tone, however I don't know anything about C# as a programmers language...) and the examples there are in VB.NET are about extreme big applications like digital piano's etc.

Label5.Text = (Int(Rnd() * 6)) Generate the first tone.
If Label5.Text = 0 Then
Label1.Text = "A"[code].....
But fore some reason, when the program has played the first tone, it won't play the rest. Why?

How can I play a tone or beep using VB.NET. I don't want to use Console.Beep() because I want the tone to always come out of the speakers, not the speaker on the motherboard.Goldfish64

I'm using the below function to generate an MD5SH1 hash for SQL backup files.This works well, has progress report etc but is slow if using large files.
Could I generate the MD5 at the same time as SH1 rather than having to process the file twice, doubling the time taken? What about converting an MD5 result to SHA1?

how to generate the formula. want to use arraylist to store and for loops to loop the formula til the system can detect which staff it should giv the ticket to..below is the scenario:this is a helpdesk system..so each ticket they submit muz be auto assigned to a staff to attend their ticket..each staff has a different quota..so i came out wid this algorithm on hw to determine who the ticket shld go to..
for ex: i set one ticket's quota is 7%
staff A's quota - 47% staff B's quota - 35% staff C's quota - 18% so to knw how many tickets A get den B getx 1 ticket and how many tickets B get den C gets 1i came out wid a calculation like this -
Staff A - 47% / 7% = 6.7(max no.of tickets he can receive foe a period of time)
Staff B - 35% / 7% = 5
Staff C - 18% / 7% = 2.5
so first i compare A&B whr i took 6.7/5 = 1.3 -> so every 1.3 ticket A gets,B gets 1 ticket den i compare B&C whr i took 5/2.5 = 2 -> so every 2 ticket B gets,C gets 1 ticket i wanna implement this concept in my code..but i dunno how to come up wid this formula..

basicaly i'm on a project which involves generating programs on the fly from a website, these programs will have the ids of the logged in users.To do this, I found a little trick, which is having a vb.net program running on my windows server communication with my website's database and generating another executable then send it back to the client.Anyway this is just some boring introduction, basically my question is how can I generate an executable from my vb.net executable?

On Stack Overflow, I found the question Generate a receipt number in this range.In answers (from Adam Maras) I find this code (very interesting for me):
Private Const FirstReceiptNumber As String = "GA00000"
Public Function GenerateReceiptNumber(ByVal lastNumber As String) As String
If lastNumber.Length <> 7 Then
[code]....
But show me error in GenerateReceiptNumber().ow do I use that code to give me a receipt number in TextBox1 when I open this form?The receipt number must be +1 next time with Form_Load.

I have a large .NET source tree (185 C# and VB projects, of which 60 are apps or websites) that i want to create a wix setup for. The general idea is to have 1 setup msi and to make each executable a feature, and to have each app be installed in a separate directory. like
%progfiles%/company/app1
/app2
/app3
[code].....
Some libraries are used by multiple apps, so the DirectoryRef would have to be pointing to multiple directories, and multiple DirectoryRefs (with different ids) would have to be pointing to the same directory (found directory alias trick), both of which seem impossible.I get the distinct impression I'm going about it the wrong way, or that I'm missing some deeper insight. (No suprise as my wix-fu is a full 3 days old)

Because once I re-bot the system it connects fine.I am going to try and PING the SERVER when it comes up next to check the connection.I tried googling this for a resolution but to no avail.Do u think I will have to reload the OS on the client machine or just the Framework.

To detect 'death of player' I am using the mouseleave event of my picturebox background (background1). Unfortunately this triggers both when the mouse enters an 'evil' and the 'points' and ends the game without the player being able to collect points.
The obvious way to solve this would be to swap detection to entering evils.
Unfortunately I am dynamically creating my 'evils' and do not know how to also dynamically create subs to deal with MouseEnter. Here is my code for generating the 'evils'
'The number of evils (asteroids)
Dim evilcount As Integer
'A count for use with comparison to evilcount
