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>

Thanks in advance
hugo

1. The active x control may need to be installed and registered on the
client.
2. The .NET control will not work unless it has the privilege to do so. The
steps are as follows.
a. Add the site the control is coming from to you Trusted Zones in IE (.
b. Go into the .NEt Framework Configuration snapin (usually found in
Administrative Tools in the Control Panel)
c. Navigate the tree to the following location
My Computer/Runtime Security Policy/Machine/Code
Groups/All_Code/Trusted_Zone
d. Right mouse click 'Trusted_Zone' and go to Properties
e. On the 'Permission Set' tab, choose the permission set that gives the
control the permissions it requires

I hope this helps
