Hi Ken,
this is not a remoting problem, but ...
As far as I understand, CopyLocal property only instructs the compiler,
that when it builds the project, it shoud make a copy of the referenced
dll in the directory, where it places youe executable. If you turn it to
false, it will not copy the dll, and your app will can not find it.
Possible solutions:
1. manualy copy the dll in the directory of your exe
2. register the dll in the GAC
3. I'd recomend you to leave CopyLocal to true. Thus if you make a
changes in the dll and recompile it (it'll be compiled with a new vesion
nr), when you recompile your app, it'll have the right dll.
Hope that helps
Sunny

Hi All,
I am trying to create a gateway to a database as a dll which will be
installed on a remote server (on our intranet) but have run into a whole lot
of problems, but my immediate problem is very simple.
How can I reference a dll which is not copied locally?
I create a solution consisting of 2 projects. The first project is a class
library which consists of a single class with a single method which returns
the string "Hello World".
Public Class foo
Public Function bar() As String
Return "Hello World"
End Function
End Class
The second project is a windows forms application which references the first
project and has a single form with 2 buttons, one to exit and one to call
the method in the class of the first project and pop up a message box.
Public Class Form1
Inherits System.Windows.Forms.Form
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button2.Click
End
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
Dim foo As New RemoteLibrary.foo
MsgBox(foo.bar)
End Sub
End Class
Hunky Dory cool, I click on the button and I see "Hello World". Marvellous!
So, then I remove the reference to the first project and add a reference to
the compiled dll and run the project. "Hello World" - no surprises there.
However, my aim is to reference a remote dll and I want to simulate this
situation. So I look at the properties of the reference to the dll and
change "Copy Local" from true to false. I run and click on Button1 and I get
an error - System.IO.FileNotFoundException - File or assembly name
RemoteLibrary, or one of its dependencies, was not found.
If I run the compiled Windows Forms exe, I get the option to view more
detailed error information. (See end of post).
From the searches I have done so far, I think the key to solving this
relates to publisher policy. Am I right and do you have any good info on
this?
Also when creating the reference, I browse to the DLL on my local machine,
so why in the error details is there an attempt to "download" an EXE?
Any help greatly appreciated.
Cheers,
Ken
