ActiveX problems in IE

Jack L · Postby **Jack L** » 19 Jul 2006 05:03

I am using the activex plugin in IE to display 2 videos and have run into a couple of problems.

1. At times when closing the browser an error will appear. This also happens at times when I refresh the screen. I think it may be related to shared memory between the two instances of the plugin object, but I am not sure. Any ideas?

2. My HTML code starts playback of a video stream (multicast) but when the user moves the mouse over the plugin it tells them to click to activate. When they do the video disappears. What can I do to deactivate this "feature"?

3. I have been reading all the documentation I can find but I am confused. I am trying to find out what controls there are that I can use. I can find the methods but I cannot find a list of variables. Can anyone help.

Thanks in advance everyone.

The #2 items sounds similar to a "feature" of zonealarm - part of the zonealarm Privacy settings. If your user has zonealarm or another firewall, might be worth having them turn it off to test.

krsna,

Thanks for the reply. The article was interesting but I don't think think your question on interfering programs causing problems is the case here. The machines in question are not running any special software like you mention. My tests make me believe that my problem is due to trying to do something with the control before both of them have fully loaded.

One think I have done is move to using Microsofts .HTA approach (hypertext application). By changing the extension and adding a line in the html page it causes the system to treat the web page as an application.

It took away the problem of the video disappearing with a click, and appears to behave better this way.

The code I have displays 2 videos and allows you to switch between audio 1 and audio 2. Since I have seen some questions from people on how to do this here is the code to do it. Copy this code to a file with an .HTA extension and run it just like any executable. When you run it this code looks for 3 parameters - 2 IP addresses and text for the window. It is pretty simple to edit to do what you want. Hope it helps someone.
