[RESOLVED] Dim t1 As New Threading.Thread(AddressOf VARIABLEHERE)

[RichardG]

Hi all,

Apologies if this has been answered before, I suppose it's possible that I've been Googling incorrectly, though I did my best to look around for this information before posting.

I am self-taught, so there's a distinct possibility that I am doing this 100% incorrectly. I have a few vb.net programs which invoke threads pointing to different subs, generally the syntax for this would be as follows:

Public Sub MainSub()
    Dim t1 As New Threading.Thread(AddressOf SecondSub)
    Dim t2 As New Threading.Thread(AddressOf SecondSub)
    t1.Start()
    t2.Start()
    t1.Join()
    t2.Join()
End Sub
 
Public Sub SecondSub()
    'Do some multi-threaded operation here
End Sub

As far as I can tell, this works perfectly. But imagine if I used that method of spawning threads and I wanted 64 threads (rather than 2) running SecondSub at the same time. You'd have to write down Dim t1 through Dim t64, along with 64 Start()'s, and 64 Join()'s. It's a large chunk of code, and I call multithreading a few times throughout my project. I thought I could minimize this by only writing it once in a Generate_Multithreading sub, and then sending the target sub name into it like this:

Public Sub MainSub()
    Generate_Multithreading("SecondSub")
End Sub
 
Public Sub Generate_Multithreading(ByVal targetSub as String)
    Dim t1 As New Threading.Thread(AddressOf targetSub)
    Dim t2 As New Threading.Thread(AddressOf targetSub)
    t1.Start()
    t2.Start()
    t1.Join()
    t2.Join()
End Sub
 
Public Sub SecondSub()
    'Do some multi-threaded operation here
End Sub

This causes an error: "'AddressOf' operand must be the name of a method (without parentheses)."

I am confident that this is because my targetSub variable is a String, and AddressOf doesn't accept strings. So what should I make targetSub in order to make AddressOf happy? Is it even possible to point AddressOf at a variable of any kind?

If not, maybe I'm just going about the multithread generation stupidly? As I said: I am self taught, and I am willing to admit that I know very little.

I'd appreciate any advice! Thanks in advance!
