VB implements multithreading in COM.
When component with time consuming code executes it hangs
client for a period. Through Multithreading COM can execute
simultaniously with Client.

Answer / joby cheriyan

Multi threading is one method for using the maximum
resource allocated for an application by the OS.
For example try a VB6 code.
Add these Controls to a form List box and command button.
Private Sub Command1_Click()
For i = 1 To 100000
List1.AddItem i
Next i
End Sub
This code will hangs up your form.
Think that you have three list box and three command button
for adding into three list boxes same time. U won’t be even
able to click the button until one task completes. If you
try with DOEVENTS function also not a proper solution for
this problem. Now you will try to solve this issue with
multithread. In VB6 you need API for creating threads.
Actually VB6 has lot of crashes when we use multithread.

What happens if we need our Process to do more than 1
thing, like execute query and write to a database at the
same time. Luckily we can split a Process to share the time
slice allocated to it. This is done by spawning new threads
in the current Process. These extra threads ares sometimes
called worker threads. These worker threads share the
processes memory space that is isolated from all other
Processes on the system.
