First of all thanx for your kind help. Kindly help me on the following problem.

I have a logbook which keeps the record of all fault booked by different subscriber.this logbook has three attribute downtime,uptime & total duration (date &time format) . I want to calculate the total duration automatically whenevr uptime value is given and if the uptime is not given it should calculate depending upon the system present time.pleas explain it with example.

thanking you 

May I kindly ask you to Google how to start/stop a service from the command line.

From the command mode i am not able to stop and start  (elogd stop). But i can start/stop from services  .Kindly help  me stopping/starting it from command 

Stop the old server first, but we told you this already on elog:67770. If you don't follow our suggestions we cannot help you.

I tried it but still it gives error like Shell execution not enabled via -x flag 

Modify the server start command in the Windows Registry. Or start the elogd server directly in a command window with "elogd -x", after "cd" to the elog installation directory.

How to execute  the batch file  in elogd

Sorry, I wasn't sufficiently clear. The issue I mentioned only applied to images that are inlined in the body of the post using the "Image" button in the CKeditor toolbar.

Oddly enough, on this logbook, I am not able to upload an image in that way; after selecting the image and pressing "Send it to the Server," nothing happens.
