windows user control problem at IE

[hugo batista]

Hi

Sorry to crosspost, but i'm not knowing what should be the correct newsgroup
for this....

I have a web application which i want to show a windows forms user control
in my web form. (lets call this control userControl1)

I have no problem to do this, but when i use a COM / ActiveX control in
userControl1, and try to show it in IE, it fails, without any error. Any
clue ?

I'm showing userControl1 like this:
<OBJECT id="rtfcontrol"
classid="http://localhost/testEmbed/controls/userControlLib.dll#userControlL
ib.UserControl1"
VIEWASTEXT>
</OBJECT>
Other help
If i activate IEHost log, i get the following log file:

URL: http://localhost/testEmbed/controls/userControlLib.dll
Zone: 2
Assembly Name: userControlLib.dll
Type Name: userControlLib.UserControl1
