VWD - Viewing OWC Chart within asp page

Hello,

I've got an OWC Chart generating within an asp page based on a database populated dropdownlist value. When I log into a PC myself (and administrator on the web server) and view the page, everything runs fine and the page generates properly with the gif file containing the graph displaying in the browser. When another user logs in to the same PC (who doesn't have admin access on the webserver) and tries to view the page, the gif file image is not displayed. There's no errors, they can view the dropdown list of values but the gif file is absent (apart from a red cross where the image should be). I obviously don't want to give the users admin rights to the server to run this page, but is there some other privelages they need to view the gif's ? Maybe around access to the COM object used to generate the gif ?

Thanks

Hi,

Based on my understanding, when the user log in your computer as administrator role, the image file appears correctly; however, when the user log in the computer as another role which doesn't have the admin permissions, the image file doesn't appear. You don't want to grant admin role to the user. If I have misunderstood you, please feel free to let me know.

The reason that the image doesn't appear is that the user doesn't have the proper permissions. Firstly, we should make sure that the chart is generated correctly. If we don't want to grant admin role to the user, we should make sure that the user has read permission on this image file or folder where the image is placed.


I hope this helps.


Figured it out. Looks like when the OWC call is made to the data for the chart the user requires named access to the specific database source. The populatio of the initial dropdownlist is made before the OWC call.

Thanks anyway.
