Active X Component can run Power users group but not in users grou

[Wilmer Hernandez]

An ActiveX component created using ATL under Visual Studio 2003, and it is
used in a ASP, runs perfectly under administrator or power users group,
however this same object does not run under the Users groups.

I see this problem happen in Internet Explorer 6 and 7 under windows XP.

Under the Users group the component fails when it tries to call for the
first time a method in that component then the JavaScript throws the
following exception:

message = "Object doesn't support this property or method"
number = -2146827850

I’ve follow a trial and error approach by changing privileges to the Users
group and to the component dll several windows components such as “Component
Services" , or to the Interfaces in ole viewer, permissions to directories,
lower IE security settings in the different zones for ActiveX components
without much success.

I was wondering if anybody have run into this issue before and know what
privileges I will need to change in the users group for this ActiveX
component to run? Is this a possibility?

If this is the right forun to place this question, my apologies.

Thanks

This is a browser problem so this not the best place for the question.

However I'm not sure this is a permissions problem. Its an unusual error to
receive for a permissions style problem. Does the problem happen with all
mehods of the object or just one of them? Is the object being sucessfully
created? Is it safe-for-scripting, if so has it been registered as such or
implemented the appropriate interfaces?

First thing you should do is compare the settings for internet explorer for
the standard user with the admin user. Does the site you are visiting
appear in the same zone. Are the advanced settings and the zone setttings
etc the same?

Thanks Anthony for your response I really appreciated.

The Object seems to be created without a problem, however since the
Initialise method is the first method we need to use to start up the object,
I have not been able to execute any of the other method since the initialize
method is required for the component to work.

The Object is not safe-for-scripting; however this would not be an issue if
the "Initialize and script ActiveX controls not marked as safe for scripting"
security setting is enabled. or would it?

I have compare the setting in for both groups in IE and there no difference
that I can notice. The site that contains the dcom object is in the trusted
sites zone for both the Admin and Users group.

Do you know if the Interserv.asp.components is the best place to post this
question?

Cheers,

Have you reviewed the resources and components that the initialise method
relies on?

Even if calling another method may fail since initialise hasn't been called
it would help in diagnosis to know whether this error is unique to
initialise and yet other methods at least attempt to run albeit failing due
to a lack of initialise call.

Have you tried instancing and using the component in a VBScript file?

Do you know if the Interserv.asp.components is the best place to post this

Technically the best place for this question is inetexplorer.scripting but
that group isn't all that busy these days.

Anthony,

I've tested the ActiveX component trying to call any of the other method in
the component and the result were the same "Oject does't Support this
property or Method" message.

I'll try to initialized it in VBScript and let you know of the restults.

I'll try and post this message in the inetexplorer.scripting forum as well.

Thanks,
