Re: host a windows user control File access

If you use the OpenFile() method you get back a stream that is read only - this works with the Intranet/Internet permission set.

In the IntranetZone you have unrestricted access to the file dialogs - including the SaveDialog.

If you need more - you have to modify the security policy on the client

I have an internal app that is complex enough that I'd like to user
either create a windows app or use a windows user control in an
aps.net web page.

The windows version uses the fileOpen component. I've modified the
program to be a user control and access the data for the controls via
a web service. I haven't found a clean way to use the file open
component so that the user can access a file for processing. Is this
possible? I know that this is breaking some internet security
standards, but it's an internal app. I'd like to avoid a messy
situation where the framework security needs to be modified on the
client.

If this isn't possible, can someone suggest a better design strategy?

App Overview:
------------------------
Read data from db to poplute datasets need in the processing
User reads in a file from disk that needs some heavy UI processing
The results are sent back to the db
I really appreciate any suggestions. I though this was a security
issue. I apoligize if this was posted to the wrong group.

Thanks,

Gabe
