Using ActiveX controls in Web

Hi,
We are planning to use some Microsoft Activex controls (like Tree view) over the web and I would like to know the issues and draw-backs of using them over the web
- I know Security and Safety is the main concern of using Activex controls over the web,since it's from Microsoft authorized controls this is not an issue in our case
- Secondly the download to User's m/c is another issue
since it's for private customers and as well as it is a one time download this is not of big concern either in our case
- thirdly most of the controls are browser dependent and some of them won't work in Netscape
Since we are targetting only IE this is not a concern either

Other than these concerns I would like to know how will it affect the performance over the web,is there any issues and over-heads related using them over the web
and in terms of using client-side memory and prrocessing

Thanks in advance!

It looks to me as if you've already considered everything that would be an issue.

Since ActiveX is on the client side, performance is dependent on the client's cpu and memory. I think the hit would be negligible. If you are using common controls, the chance that there will be a download is remote. All modern Windows machines have Treeview on them already.

I think the only performance hit you'll see will be from your scripting.
