How to report host from non visual plugin progress?

Hydra

Hi,
i want to move functionality into non visual plugin.
The host should load plugin, start plugin. Then the plugin does its job.
When it is finished, the plugin should contact the host, so that the plugin can be unloaded.

How can i archive that (.net)

Hello

Hydra ships with a .NET host sample (just ignore the projects that will fail to open, like Oxygene ones). The sample can be found in the folder

 c:\Users\Public\Documents\RemObjects Samples\Hydra for NET\Mixed Mode

The project ManagedCSharpHost. is a simple host application that supports both visual and non-visual plugins. Also Hydra provides a template for non-visual plugins. Take a look at this article, it describes how to create and use non-visual plugins: http://wiki.remobjects.com/wiki/.NET_Non-Visual_Plugins

Hope that helps

Sorry, but it seems that you misunderstood me
The request for a working example was for synchronizing non visual plugin with hist, all in C#

Thnaks in advance.

You’d need to define a custom plugin interface:

Add a new Class Library project to your solution.

Define there plugin interface like

public interface IPluginModule
{
    void Execute();
    event EventHandler Completed;
}

Reference the newly added project from the plugin project and implement the interface by the non-visual plugin.

Reference the assembly containing the interface definition from the host application

Once the plugin is loaded check its type and start it:

(this.fCurrentPlugin as IPluginModule).Completed += (s, ea) => { MessageBox.Show("Done!"); };
(this.fCurrentPlugin as IPluginModule).Execute();

The plugin will be able to send a signal to the host via raising an event.
