Is it worthwhile to write an ActiveX module dedicated to drawing charts?

[lucky6969b]

I know the user installation must involve some registry manipulations and
some other trickery. But the ActiveX way seems to be more modular.
Is it worthwhile to separate the charting modules from the exe and make an activex dll
for this purpose?
Thanks

It depends on the ultimate purpose. ActiveX is mostly suitable for cross-language applications, or being re-used in a certain family/domain of applications. Or in case your intention is to make some business on selling the component. In the latter case you're going to compete with really big players on the market.

Thanks.... I don't mind if I could reuse some other's work unless I have to pay a big deal.

If you don't already know COM, writing an ActiveX control is kind of a big undertaking.

If you don't already know COM, writing an ActiveX control is kind of a big undertaking.

Even if you DO already know COM. It is still kind of a big undertaking (compared to a "simple" library, dll or set of (template) classes).

Here's an article with source code. It's not charts but it is ActiveX and it draws something,
