Hello everyone!
Is that possible to give matlab oobject as argument to .Net function? Actually I want to execute some class member asynchroneously. Therefore, the BeginInvoke method should pass the handle of related object to asynchron function. I am using the NetDocDelegate.cs defined in the documentation to which I have added the following line :
public delegated double delRef(dynamic arg);
and my class definition is defined as :
classdef usier < handle
properties
stock
value
end
methods
function obj = usier(stock,value)
obj.stock = stock;
obj.value=value;
end
function receive(obj,objref)
divDel = NetDocDelegate.delRef(@response);
asyncRes =divDel.BeginInvoke(objref,@obj.display);
end
function result=response(obj)
result=[obj.stock,obj.value];
end
function dispay(obj,asyncRes)
result = asyncRes.AsyncDelegate.EndInvoke(asyncRes);
fprintf(1,'neighbor''s stock is:%d\t and value is:%d\n',result(1),result(2));
end
end
end
Then I created two instance of usier class
>>u=usier(12,34);
>> f=usier(45,98);
>> f.receive(u)
the last command should executes the asynchron function and then retreives the result. unfortunately matlab generate the following Error:
No method 'BeginInvoke' with matching signature found for class 'NetDocDelegate.delRef'.
ps:I added the assembly files first with
dllPath = fullfile('c:','MATLAB\DynChannel\','NetDocDelegate.dll');
NET.addAssembly(dllPath);
can someone help me?
Thanks all,
Bolivar
