Hi,

I need help writing the c# code for the the following method:
http://msdn.microsoft.com/en-us/library/hh418696.aspx

I need help understanding how to write code to receive the ACTION part of the method. In particular:

initialized
Type: System..::..Action
Called when the node is initialized.

shutdown
Type: System..::..Action
Called when the node is shutdown.

error
Type: System..::..Action<(Of <(<'Exception>)>)>
Called if an exception is raised in the node lifecycle management.

Here is my code so far:

using Microsoft.Dss.Hosting;
string ManifestToLoad = Settings.Default.Manifest;
DssEnvironment.Initialize(50000, 50001, ManifestToLoad);

I really need to know if there has been and error during the loading of the Manifest. Please let me know if you need more info.

Thank you!

You need to create 3 delegates that will be used as callbacks for each of the 3 scenarios required by the method signature. In other words, try modifying your call to something like this:

DssEnvironment.Initialize(50000, 50001, ManifestToLoad, OnIntialized, OnShutdown, OnError);

Open in new window


Then define those three methods within your class:

private void OnIntialized()
{
    MessageBox.Show("Initialized");
}

private void OnShutdown()
{
    MessageBox.Show("Shutdown");
}

private void OnError(Exception ex)
{
    MessageBox.Show("Error: " + ex.Message);
}

Open in new window

that is basically nothing else than a function (or often just a "delegate" function code):
