Hi,

You can invoke the child workflow using an InvokeWorkflowActivity from a state machine.

To call an Event Driven activity in the child workflow you need the InstanceId of the child workflow and use it to create your ExternalDataEventArgs. When you fire the event, the Workflow Runtime will use this InstanceId to route the event to the proper running Workflow. I can provide a sample if you wish and post it on my blog.

Thanks,

Steve,

I need to use InvokeWorkflowActivity to call an XOML only workflow. I know how to do it via CreateWorkflow, but am not sure how to do it with this activity. Below is the code I probably need to substitute for the XOML file, Rules files, and paramsCollection:

this.invokeWorkflowActivity1.Name = "invokeWorkflowActivity1";

this.invokeWorkflowActivity1.TargetWorkflow = typeof(WorkflowConsoleApplication1.SubWorkflow);

Any ideas how to replace TargetWorkflow to specify the xoml only workflow

Thanks in advance,

John Portnov
