I create COM DLL with VB.NET.
I decided to add code in my COM DLL to create Tread. Here is the line of code I use:

'--- COM DLL code----->

loProcessThread = New Thread(AddressOf ProcessCustomData)

'--- COM DLL code-----<

But loProcessThread is always Nothing. It seems .NET does not want to create additional thread within COM DLL
(there is nothing about VFP in my question)

Thanks
