Creating an ActiveX control

[maverick786us]

For retriving the MAC address of a machine I found this thread pretty much helpful.

Now I have to create an activeX control that can be used by any microsoft language and they can use my function to get the MAC address. Can anyone help me ??

I mean where exactly should i write those functions so that other languages can use them

Hi,

Create a DLL using ATL COM that exposes your functionality. Take a look
at Variants, BSTR and SafeArray which would help you use your code
from other languages.

There is already one:

WbemScripting.SWbemLocator

I used this to verify that a user was connecting from a trusted machine in a webpage.

Graham I am not allowed to use a third party control. The company has given me task to create one of my own

Hi,

What graham meant was using WMI. Its not a third party tool. Its from MS
and u can use it at will.

OK Girish can you tell me just some basic steps to create an COM DLL which can export functions which can be by other Microsoft languages.

Besides COM DLL I even have to develop an ActiveX control which will get loaded in the browser, and once it gets loaded it will perform its action (Special functions). So in which header file should I call those functions??

Hi,

Take a look at http://www.codeproject.com/atl/SimpleATLCom.asp

That should give u a headstart.
