Remoting and OpenFileDialog

Valerio

7/13/2004 11:34:00 PM

Hi all,
i've a big problem ^^..
the class OpenFileDialog is a MarshalByRefObject, so i've registered it in
..net remoting:

TcpServerChannel _channel = new TcpServerChannel(9932);
ChannelServices.RegisterChannel(_channel);
RemotingConfiguration.RegisterWellKnownServiceType(typeof(OpenFileDialog),
"OpenFileDialog", WellKnownObjectMode.SingleCall);

but when i try tu use it client side

object o = Activator.GetObject( t ,
"tcp://"+_hostName+":9932/OpenFileDialog");
((OpenFileDialog)o).ShowDialog();

i got a strange error:
it tels me that the server cannot load or find file or assembly
System.Windows.Forms !
at the beginning of stacktrace there is an Assembly.nLoad(..);
i can't understand why...

Thanks all !

By default, when SAO''s are instantiated by the remoting infrastructure, it
uses a partial assembly name to do so. That means that the assembly
containing the remoted class must be in the same directory as the remoting
server (or in a directory specified by the <probing> element or directly
referenced by the <codeBase> element in the app''s config file). It will not
look in the GAC with only a partial name.

So, on the server side, you have to tell the remoting infrastructure to use
the full assembly name as follows:

WellKnownServiceTypeEntry e =
new WellKnownServiceTypeEntry("System.Windows.Forms.OpenFileDialog",

"System.Windows.Forms,version=1.0.5000.0,publicKeyToken=b77a5c561934e089,cul
ture=neutral",
"OpenFileDialog", WellKnownObjectMode.SingleCall);
RemotingConfiguration.RegisterWellKnownServiceType(e);

All of that said, I would highly recommend against what you''re doing. First
off, because you''ve made the object a SingleCall SAO, you''ll never be able
to get the filename selected by the user on the client side. The property
invocation FileName will cause a second OpenFileDialog to be instantiated on
the server. Secondly, because it''s SingleCall, you can''t call Dispose() on
this object when you''re done with it, so it will take up server resources
until garbage collected.

If you really must do this, I''d create my own wrapper class which is a SAO
singleton and exposes a method such as:

public MyServer : MarshalByRefObject
{
public string PromptForFilename()
{
using (OpenFileDialog dlg = new OpenFileDialog())
{
dlg.ShowDialog();
return dlg.FileName;
}
}
}

Thanks very mutch !
I''ll try it soon ^^
I know the problem of the SingleCall, is because the code was a cut and
paste :)

If you dump the entire exception you should see the runtime''s probing
information after the main exception info. For example, here''s what I get if
I change the full assembly name (with version, public key token and culture)
to just the name "System.Windows.Forms":

=== Pre-bind state information ===
LOG: DisplayName = System.Windows.Forms
(Partial)
LOG: Appbase = C:\Documents and Settings\Kkolda\My Documents\Visual Studio
Projects\RemotingExample\Server\bin\DebugLOG: Initial PrivatePath = NULL
Calling assembly : (Unknown).
===

LOG: Policy not being applied to reference at this time (private, custom,
partial, or location-based assembly bind).
LOG: Post-policy reference: System.Windows.Forms
LOG: Attempting download of new URL file:///C:/Documents and
Settings/KKolda/My Documents/Visual Studio

LOG: Attempting download of new URL file:///C:/Documents and

If you can include this info in a post I can try to tell what''s going wrong.

If you convert the exception to a string using ToString() you should get
some info below the main exception stack trace similar to what I showed
below. It starts with the line "=== Pre-bind state information ===". That
shows where .NET is looking for the referenced assembly ( a process called
"probing").

I don't know what differences there may be in the Italian version of .NET in
terms of the culture info or version number on the assemblies in the
framework. What you can do is check in the C:\Winnt\assembly folder and look
for the System.Windows.Forms assembly and see if the version number, public
key token or culture are different than the ones I provided. (If the Culture
column is blank, that means Culture=neutral).

Also, I can't tell if this is the case, but it looks like you may have an
extra leading space in the name of the assembly in your
WellKnownServiceEntry. Notice the extra space in the line

Nome file: " System.Windows.Forms"

before the word System.

That was the problem! Thanks !!!
Peraps is not what i wanted to do :(
I would be able to browse a remote filesystem but with this method the
openfiledialog is opened in the server and not in the client :(
Do you know some way to do that?
