Question

Html listener fails to produce output unless user with admin rights runs report once

Asked by: tmedley

We use a vfp active X exe to creaet reports from another application by having the vfp app write the report to disk as an html file using the html listener object. We then view that file through a browser control. When we distribute the exe along with vfp 9 runtime and the required .app files for the report listeners vfp ships with we have a problem. The vfp exe will send reports to the printer just fine but when we send it to the html listener we get a silent error and no output unless a user with admin rights on the workstation runs the process one time. After that any user can do it. I have diffed the registry before and after and checked env settings like path before and after. I cannot find any evidence of what running it once as an admin user changes. This is in an XP environment. Does anyone have any ideas? Does anyone have a good list of what the VFP listener process requires and specifically the HTML listener class. We know it needs MSXML and SOAP and those are definitely in place and registered. I am beginning to suspect some kind of policy setting for token objects maybe? Once an admin has let the process run through which requires some kind of credentialling by the listener to use a "secured" component then the listener class can always do it regardless of who the user is maybe? Where would such stuff be if not in the registry?

Today I answered my own question. When you use the listener class with vfp, wherever vfp is running from if there is not already an outputconfig.dbf/cdx/fpt for it to use then it will create one. In a delivered environment if vfp runtime is in system32 or some other directory that a normal user does not have rights to create files in then it will fail silently. Runnin git one time as admin creates those files. One solution to this is to deliver those files with the installation package, another is to have the package create and use the listener one time (since the assumprion is that the packahe will be run with administrator rights.

Great tip.

I just converted a VFP6 app over to VFP9 within the last two weeks.  So, the use of the newer VFP9 object-assisted reporting hasn't been required yet.   I had to concentrate on the SQL changes which were a few more than I originally thought.   I also had to be aware of a few class revisions that broke things, which I didn't expect.  So, to get it all going, I liberally used SET REPORTBEHAVIOR 80 until the rest of the app now in production seems stable.  Then the newer VFP9 reporting will have a better chance to get applied.
