Hi all,
My company purchased a third party solution recently and want to deploy to production farm. There is a visual web part in the solution and it doesn't work when I install at the first time in the test farm. After checking with the vendor the response is that the web part loads for the user logged in, it needs a folder to render images temporarily. The developer creates a temp folder at SP hives/images/tempimages. When the web part chart renders initially, the temporary images are written to the folder and the chart is displayed. For the chart to work, users on the portal require write permission to this specific folder so that folder needs to open up (grant "Write" permission) for every users. With all the third party tools we purchased this is the first time I heard we need to open up system drive permission to all users (may include "everyone" group in the domain). Due to security reason I don't feel comfortable to do so. It doesn't seem to be the ONLY way for such task. Since we have the negociation room with this vendor for custom development just want to ask the forum and SP developers about the general practice. Is this Microsoft recommended method for visutal web part development? Does anyone in the forum purchase any solution with such configuraiton?
Thanks in advance for any suggestion and help.
Sally
