I need to execute DDE commands from the client side of an asp application (I know, it is not asp anymore, but since VScript is almost the same ...).

How can I send these commands? Is using an ActiveX my only solution (i never did one and I ama tryng to avoid it) ?

This is how the DDE commands are supposed to be run from VB or VBA:

Sub DialAgentPhonePlus(PhoneNum$)
    Dim Chanl As Long
    On Error Resume Next ' Set up error handling.
    Chanl = DDEInitiate("AGNTPLUS", "SYSTEM") 'Establish link.
    If Err Then Exit Sub ' If error, exit.
    ' Dial the Phone Number
    DDEExecute Chanl, "DIAL," & PhoneNum
    ' Terminate DDE link.
    DDETerminate Chanl
End Sub

VBScript doesn't support DDE and AFAIK there is no built in object that would let you do so.

So, is there any other way to have the client side communicate with a DDE capable application installed on the user's PC?
The users will be company employee's so we can have them download / install any needed files.
Would an ActiveX made in VB6 get the work done? ... I never did an ActiveX before and I have no clue of how should I do it.

ActiveX would work but if this is only for company emplyee where you can install things, write a very simple COM dll in any languages (VB would do) and let that communicate with that DDE enabled application. Also you might want to explore if that application exposes COM interface because VBScript can then use those interfaces directly.
