Differece between DLL & ActiveX interfaces

[Ragnar]

Could you explain the difference between the DLL interface described in eSignal and the ActiveX interface descibed in eSignal Pro. I am a software developer who is well versed in DLL's and ActiveX/OCX details so you don't need to explain conceptual or technical issues. Rather, each product's intent, functionality and capaility differences are what I am looking for.

Ragnar:

The DLL interface is used to write DLLs that will then be called from within EFS scripts. For example, if you were creating an EFS indicator that contained a rather complex calculation, you may be better served (for speed reasons) if you implemented that calculation as a DLL function and then simply called that DLL function from within your script.

The ActiveX interface allows you to write standalone applications, of unlimited complexity, that will then have access to the raw eSignal datafeed. It is similar to the Quote.com Continuum interface if you are familiar with that.
