third party tool

in a particular program i require to acess a third party encryption tool(batch file) which encrypts a file. i tried using the methof cl_gui_frontendservices=>execute . but my problem is that the program always will run in the background and this method is made to run in the foreground so it throws a runtime error. this program is a called by transaction f110 which is a Fi transaction. is there any means by which i can acess the batch file even though it runs in the background.

thx u
