Delphi Compiler Error
E2232 Interface ‘%s’ has no interface identification
Reason for the Error & Solution
You have attempted to assign an interface to a GUID type, but the interface was not defined with a GUID.
program Produce;
type
IBase = interface
end;
var
g : TGUID;
procedure p(x : TGUID);
begin
end;
begin
g := IBase;
p(IBase);
end.
In this example, the IBase type is defined but it is not given an interface, and is thus cannot be assigned to a GUID type.
program Solve;
type
IBase = interface
['{00000000-0000-0000-0000-000000000000}']
end;
var
g : TGUID;
procedure p(x : TGUID);
begin
end;
begin
g := IBase;
p(IBase);
end.
To solve the problem, you must either not attempt to assign an interface type without a GUID to a GUID type, or you must assign a GUID to the interface when it is defined. In this solution, a GUID has been assigned to the interface type when it is defined.
