Hi all,
as a newbie of C#, I am rather surprised when I saw that the method of
System.ServiceP rocess.ServiceC ontroller - ExecuteCommand( int command) - has
only one parameter. What shall I do if I want to send other data contained in
a front-end GUI, say a windows form, to my windows service (could be on a
remote host)? Following is my code snipper,
-------------------------------------------------------------
In MyGui.cs:
private void buttonFind_Clic k(object sender, System.EventArg s e)
{
try
{
serviceControll er1.ExecuteComm and(129);
labelInfo.Text = "Execute command";
}
catch (System.Invalid OperationExcept ion exp)
{
MessageBox.Show (exp.ToString() );
}
}
--------------------------------------------------------------
In MyService.cs:
protected override void OnCustomCommand (int command)
{
switch (command)
{
case 129:
cmd129Handler() ;
break;
....
The function cmd129Handler() cannot retrieve parameters from MyGui.
Any ideas or suggestions? Thanks in advance!

Hi,
Basicly what you need is IPC (Interprocess communication) ..
....to accomplish that you could use NamedPipes .. or Remoting .. or TCP/IP
protocol ...
I wroted library on that topic (IPC for .NET): http://www.habjansoftware.com/ipc_library.aspx
.... it contains IPCServer and IPCClient (and also PipeSender and
PipeReceiver) .. all based on NamedPipes ...

Hi Josip,
thanks for the concret answer. I visit your site and find that the
IPCServer/IPCClient solution is for two process on the local machine. I will
do some research about Remoting as you suggest. Thanks again!

Yes, it is for two or more processes only on local machine.
I'm glad i pointed you on right direction ..
