Launch an exe file from a website

[Caroline Bornsjo]

Hi, This is my first post, so please excuse my poor english or if I miss giving you important info. I need to start a windowless exe file from an internal website. I have been using System.Diagnostics.Process with credentiels and without. If I use it with credentiels I get a "The application failed to initialize properly (0xc0000142)." error and without I get different sort of errors from the application I am trying to start. The exe I want to start is written in C# (as is the website), and I have the sourcecode for the exe. The website and the exe file is running on the same machine (a 2003 server). The exe is also running every night by a scheduled task. I have been trying to start the scheduled task aswell, but hit a dead rock there aswell... Does anyone have a good formula for doing this? As this is on an internal website the security issues are less crusial (but still important). Best Regards Caroline

Statistically, most computer crime is an inside job. Therefore, logically, more emphasis should be put on security for internal applications. But that rarely happens.

What is the error? Also, remember that if you start the process from the web application you will be using the same credentials as the web application, usually the ASPNET account. Could it be that the application requires more rights to operate than the ASPNET account permits?

Are there any error messages from that scenario?

The error's I get from the application is 1.System.Security.SecurityException: That assembly does not allow partially trusted callers When I got this error, I added the ASP-user to the security tab of the exe file. After that I got the next error message: 2.An unhandled exception ('System.IO.FileLoadException') occurred in BankService.exe And I was stuck again... When I run the Scheduler task option I did the following exeProcess.StartInfo.FileName = "schtask"; exeProcess.StartInfo.Arguments ="/run /tn BankService"; and exeProcess.StartInfo.FileName = "cmd"; exeProcess.StartInfo.Arguments ="schtask /run /tn BankService"; It didnt do anything... I checked the scheduler and nothing had happened and I checked the Task manager and no process with the bankservice had started. The exe im trying to start I have stripped from doing anything but Console.WriteLine and EventLog.WriteEntry. In the webconfig file it is added (not due to this) How do I set the asp net user to access the desktop or can I get the process to run as antoher user but the net user?. The website requires you to log in with your windows credentiels... /Caroline

Sounds like what you need to do is write it as a service, I'm pretty sure you can set up a service to be called from an ASP.NET app.

if that is a .net exe then add it in GAC. with "gacutil -i exe_path" then give full trust to it with "caspol -af exe_path" use sdk command prompt. Add this in webconfig. try ur program after that.

sorry for the late reply, but had to try/fix a few things to get it all working. I have installed the exe with the gacutil tool and had to strong name type it first... Then when I try the caspol command I get an error Usage: caspol ... any suggestions on this error? I hate to be forced to make a service out of this.... Thanks for the help by the way :) /Caroline

Made the service and is stuck on yet another access denied problem... When I try to start the service myControl = new ServiceController("StartSchTask"); String[] args; args = new String[2]; args[0] = "BankService"; args[1] = "cl@ikaros.se"; myControl.Start(args); I get the "Cannot start service StartSchTask on computer '.'." error and I believe that this is an access denied error.... any suggestions...*banging head into the wall...* /Caroline
