executing an exe located on anther computer?

[erman.olca]

Hi all,

I have a question for you. I used a program two days ago. there was a
lan and program was just on one computer. But other computers have its
short cut icon on their desktop. And it runs. When i came home tried
to do same thing on one of my ex-projexts. But i could not be
succesfull. It gives System.Security.SecurityException. How can i
handle this problem. Can it be possible to use an exe located on the
other computer written by .NET c#?

It's possible, but you would have to turn off security to do it. Very
dangerous thing to allow...

add my exe to allowed program list but it did not make anu effect.

The other computer is considered to be in the Local Intranet if you
reference it by a UNC name or a mapped drive using it's computer name. Any
..Net application running from another computer has to have the security set
accordingly. There is a wizard to trust assemblies or to change the settings
for a zone in Adminstrative Tools (W2K / XP). Note that if the computer has
only the .Net 2.0 runtime (not the SDK) then the wizard is not installed and
caspol has to be used which is a command line utility. For example to fully
trust the Local Intranet zone you can use
%windir%\Microsoft.Net\Framework\v2.0.50727\caspol -cg 1.2 FullTrust.

If the reference to the other computer uses an IP address then it will be
considered part of the Internet zone and I would NOT adjust security to
allow this to run. Change to UNC type reference, e..g
\\SERVER\share\file.exe

First thanks for your reply. Its now ok than. I have an database
connectivity problem now. How can I programmatically discover the IP
address or hostname of the computer on which
my assembly is executing? thanks a lot again for your replies

I gather what you are trying to do is find the database server that is
located on the same computer that the executable is located. The assembly is
not executing on that computer though but on the computer that you are
running the software on. Application.ExectablePath will give you the path to
the assembly but that might not help you too much. Generally you would put
the settings in the App.config file because the database server might be on
a different computer than the application server.
