You either have to copy it to the other machines that are going to use it or copy it to a share on a server. But, in the later case, you MUST be aware of Code Access Security and how it affects your code. Code running from ANY network resource, trusted or otherwise, is NOT trusted code as far as the local machine is concerned. Your application will be running, by default, in a heavily restricted sandbox. What works fine is launched from on the local machine can quite easily fail if run from a server because of CAS. You can read about it here[^].

Here's a small thought, perphaps it can be of use.

Try making (instead of a shortcut) an actual application that
when run, locates the exe in question from the server, and copies it over and then executes it
locally.

I do that with some simple programs, and i also add a simple "version" check to see if the
exe is newer than the one on the local machine. (by checking creation date of the exe)

the program could have something like:

<br />
Public Class Form1<br />
<br />
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
<br />
        Dim remoteEXE As String = "\\server\C\Folder\myExe.exe"<br />
        Dim localEXE As String = "C:\Folder\MyExe.exe"<br />
<br />
        If My.Computer.FileSystem.FileExists(remoteEXE) Then<br />
            If My.Computer.FileSystem.FileExists(localEXE) Then<br />
                If My.Computer.FileSystem.GetFileInfo(remoteEXE).CreationTime > My.Computer.FileSystem.GetFileInfo(localEXE).CreationTime Then<br />
                    My.Computer.FileSystem.CopyFile(remoteEXE, localEXE, True)<br />
                End If<br />
            Else<br />
                My.Computer.FileSystem.CopyFile(remoteEXE, localEXE)<br />
            End If<br />
        End If<br />
<br />
        Shell(localEXE, AppWinStyle.NormalFocus)<br />
    End Sub<br />
<br />
End Class<br />
<br />

The only security my simple solution could offer is the security defined by your domain (i.e. Active Directory and policies in a windows environment)

Well instead of the shell function, try using the Process.Start function

i.e. Process.Start(localEXE)

1) do you have the right permissions set up on your network ?
i.e. can the host manually copy paste the file in question?

2) are you connecting to the server correctly ?
if you type in \\putservernamehere\someshare\somefolder does it connect directly?

this solution is an anorthodox solution, and it works for me in a well set up domain
where each host has appropriate access to the server

otherwise this should be done properly, by configuring the right CAS permissions to
execute the file(s).

i can't help you much more as i don't know how your network is configured

Adding components (such as DLL files) to your project means that you are accessing resources that will not be compiled in your program.

In other words you need to copy more than just the exe. Notice that if you publish your application, and view the prerequisites, you'll notice that with the built exe all the additional components will be added.

In a simple application (that will not scale much further) you should copy all the files found under your compilation directory.

(All the files in the debug or bin directory should be together with the exe file)

Most likely it's the case of that "new" dll you added.

Hi Ericos Georgiades,
u r cen % rite.yes i have dll file and i have also used a Excel component for reporting purpose in this version.
Now how do i add this ??

Eric Georgiades2-Jan-07 5:16

if it works on the machine you have developed this
then have a look at the debug (or bin) directory of your project

there you'll see all the files that the exe is directly using (assuming that the dll is copied to the output directory)

copy all the files to the host, not just the new exe.

otherwise you should publish and install your solution at least once on the host,
and then all you'll need to replace is the exe.

hope it helps

Thanx Ericos, i have done this and compiled my project using setup project wizard..

Now my doubt is how to copy the new dlls alone to the client machine so that i need not run the setup again..

The same way you did with the exe.

I'll leave this one up to you Big Grin | :-D
