Hi,
I'm trying to create a generic threading application where you can pass
in any object and a number of threads, most of it is working but I'm
having trouble creating multiple instances of the object handed down.
The code that I've supplied should simply create msgbox with 10
different messages, but it the ProcessID gets incremented for all the
threads everytime a new object is created.
Can anyone point me in the right direction.....
Thanks in advance
Sub Main()
Dim myThreadRunner As New Threader.Thread er
Dim obj As New inherSimpleObj
myThreadRunner. ThreadRunner(10 , obj)
End Sub

Public Function ThreadRunner(By Val nT As Integer, ByVal myProcess As
Object)
Dim myobj As Object
myobj = myProcess
Dim t(nT - 1) As Threading.Threa d
Dim stiThreads(nT - 1) As clsSimpleObject
Dim X As Integer = 0
Do Until X = (nT)
Dim myNewObj As New object
myNewObj = DirectCast(myPr ocess, clsSimpleObject )
stiThreads(X) = myNewObj
stiThreads(X).P rocessID = X + 1
t(X) = New Threading.Threa d(AddressOf stiThreads(X).E xecute)
X += 1

Stuart,
Did you visit this newsgroup before and have read some question.
In my idea comes your question almost one or two times a day.
The answers are mostly in it shortest format, it is not easily to get to the
UI in a workerthread.
I know it is not much maybe it helps having this information.

I have 30 - 40 type of different window.
For each type I need about 20 instances of the window.
When I try to create them, I get "Error creating window handle"
My guess is there is a maximum number of window handle, because if I reduce
to about 2 instances of each window,
it can run. But not 20 instances of each window.
Does anyone know what the problem is? is it really because it exceeds the
maximum number of window handle?

Hi
Straight to the point - I don't understand why System.Array derives
from IList (given the methods/properties actually on IList).
When designing an interface you specify a contract. Deriving from an
interface and only implementing some of it means something is wrong:
either the interface specification is wrong e.g. not minimal or the
derivation is wrong e.g. the type can't actually honour this contract.

Hi,
How Do I create an instance of a derived class from an instance of a
base class, essentially wrapping up an existing base class with some
additional functionality. The reason I need this is because I am not
always able to control/create all the different constructors the base
class has. My problem can be described in code as follows ...
/* This is the base class with a whole heap of
constructors/functionality*/

I would like to design an object using class. How can this class
contain 10 member functions. Put 10 member functions into member
function pointer array.
One member function uses switch to call 10 member functions. Can
switch be replaced to member function pointer array?
Please provide me an example of source code to show smart pointer
