OK, this must be a very very simple question for ASP programmers to answer.
After I have gathered all the information I want from the user and after
the user has clicked on a submit button, how do I make an operating system
style call on the server.
Now, I have already figured out how to create a function call in the ASP
development environment that is called when the user clicks on the submit
So my qesttion is to how to create a system level command through ASP.
Specifically, I am using ASP.NET. Let me explain further. I have just completed
a program that is very simular to the #3 AJAX demo that Joe Strgner has made on http://asp.net/learn/ajax-videos/ where he gets users to select from a group
of "CascadingDropDown" control extender classes. When the user has selected
from the third drop down control, a label is custom formatted and displays the
group of selected options.
What I want to do is this. After this is done, I want to have a "submit" button
on this page which, when the user presses it, a call is made on the server side
that will include the users selections as parameters.
Something like this, for example:
"CALL SOMEPROGRAM.EXE " selection_1, selection_2
I think I will ask this question in a simpler way.
Notepad is a program that can be launched from the command line.
I can open a CMD window (dos window) and on the command line,
I can type "notepad" and the notepad execuatble will launch and I will
see that program. So, how would I do that inside asp.net and
specifically inside the Default.aspx.cs file which will get called
when the user clicks on the send button in the function
Well, in a 'normal' .NET application you can use the System.Diagnostics.Process.Start method to launch an external application.
In ASP.NET (you can also use that method) however you'll probably run into two problems.
1. Access rights. It's not given that the account running the IIS (or the .NET working process) has access to launch external applications. This you can solve using impersonation.
2. Where should the application launch? In a normal situation the IIS service hasn't any desktop (screen to place a window) associated with it.
