Lauch application in shell with a WCF webservice

Question

Hello,

I made a WCF webservice, with some function to use an ASP.NET website with an ERP we developped.

I created a sub wich lauch an application with arguments, to automaticly print a label.

When I start my webservice in visual studio, in debug mode, it works perfectly : my process in lanched, and my label is printed. But when I deploy my webservice in IIS, on the same PC, my exe is launched but immediatly killed, withtout printing my label, and even executing my code (I write in a text file "ok" at the begining of my sub in my ERP, this file was not created....

Is there something to set on my IIS server (a user...) ?

Here is my code in my webservice :

 Shell("C:\Program Files (x86)\Videor Informatique\Everest\PJTGestcom.exe -EDIT -S:""OLIVIER-PC\SQL_OP"" -B:""MYDATABASE"" -ETQ:9145 -MAG_ETQ:1 -IMP:""EPSON TM-T20II Receipt5"" -FORMAT_ETQ:""ARTICLE"" -NB_ETQ:1", AppWinStyle.Hide)

 Is there another way to launch executable from my webservice ?

Thanck you in advance.

Sincerely

Hello,

When running in IIS the process is in the context of the application pool.  One way of handling this would be to change the identity of the application pool to a user that has permission to execute the shell command.  

Another approach would be to give the app pool identity more permission.  This post should get you heading the right direction: https://stackoverflow.com/questions/7334216/iis7-permissions-overview-applicationpoolidentity
