I downloaded ASPExec 3.0 from http://www.serverobjects.com./ - http://www.serverobjects.com. It
is supposed to allows you to execute DOS and Windows apps.
I moved the DLL in the subdirectory \winnt\system32 and I typed regsvr32
aspexec.dll

I went into control panel/services/world wide web publishing service and turn "Allow Service to Interact with Desktop" on.
I execute the program :
The results :

Attempting to execute notepad.exe
The result of this call was : Ok

I see Notepad in the taskmanager but it does not appear on my desktop.

Did i do something incorrectly?

code:

<%
  Set Executor = Server.CreateObject("ASPExec.Execute")
  Executor.Application = "notepad.exe"
  Executor.Parameters = "c:\autoexec.bat"
  Executor.ShowWindow = True
  Response.Write "Attempting to execute " & Executor.Application & "<br>"
  strResult = Executor.ExecuteWinApp
  Response.Write "The result of this call was: " & strResult
%>
I wait for your advices,

Thank so much!

I did this with the shell command in a commandline environment.  I didn't try this out with a webserver, but you could give it a shot.

set wShell = server.createObject(wScript.shell)
wShell.run("%comspec% /c run notepad.exe ")

...you need to preface the DOS command with "%comspec% /c"

The server creates an instance of the wscript shell object. It then sends an environmental variable to command.exe.  The DOS command is "run notepad.exe" .You will probably have to put the path in front of notepad.exe however.

I hope this helps.
