am using HOST command to read a files from the directory (on the server). But HOST does not working. When i click the button to read the file, it just hangs on and no error on the console.
Does host work on forms 10g?
Any suggestion.

Thanks ...It helps me in one of my scenario.
What i am doing in my case is
1. I am generating one CSV file which take around 2 minute
2. What user is doing is instead of checking the file in my destination folder (Common Drive) he is goin to generate again and again whenever he need to see the file.
3. what i am doing with this code is i am enabling one flag which user can reset any time at user level.
4. If my flag is enable i will not go and generate the file instead of that i will simply open the file.
5.Although there is no rights to delete the file but anyhow if the file is deleted from destination folder then user can reset the flag and regenerate the file.

So it saves every two minute of my 50 of users one will generate and everybody will watch ...coool ha?

Thanks buddy
