I am tally Erp9 software in windows server 2012 r2. I am using below code to connect to tally and fetch response for particular request. Code: Dim TallyRequest As WebRequest TallyRequest = WebRequest.Create("http://localhost:9000") When multiple users connect to server computer and open the Tally software, only one tally instance opened by 1st user, listens to the requests. So my application is not able to connect to the other tally instances. How to connect the tally, opened in current user login?
