InvokeAssistant Method
Mercury.QTP.CustomServer Namespace > CustomServerBase Class : InvokeAssistant Method
The remote Assistant object to be invoked. See CreateRemoteObject
The method to invoke.
A list of Variant parameters.
Invokes a method of a CustomAssistantBase class in the control's thread.
Remarks
First create the Assistant class: class MyRemoteAssistant : CustomAssistantBase { public int Add(int i, int j) { return(i+j); } } Then create the remote object with CreateRemoteObject and initialize it: MyRemoteAssistant oMyAssistant = (MyRemoteAssistant)CreateRemoteObject(typeof(MyRemoteAssistant)); Set the target control once before first use. oMyAssistant.SetTargetControl(WndHandle.ToInt32());

After the target control is set, the methods of the assistant object can be invoked.

Invocation with InvokeAssistant causes the method to run in Control's thread. int i = (int)InvokeAssistant(oMyAssistant, "Add", 1, 2);

The method can also be invoked directly if it can run in any thread of the AUT process. int i = oMyAssistant.Add(1,2);
