Hi Everyone,
I have a problem with my ActiveX component, in my code, I download the
relevant WINSOCK file and then install and register it. I found that when
using the ActiveX component in my class module, it comes up with an error
saying that it cannot find the component. But if I close the worksheet and
then reopen it, the error doesn't appear, and everything seems to install
fine...not sure if that is a problem with my download and register of the
ActiveX component...
Code is below...
