But, when writing the idl interface description file found in the library cannot be identified, the parameters for each error,
Checked, have said Windows SDK question, has said the category can't identify problems, should be the latter, I installed vs time and later did not encounter the problem of the SDK,
So, how to correct the idl file to add custom categories, parameters can be function??
Post code:
//ComCaffe. Idl: ComCaffe idl source
//
//this file will be handled by MIDL tools to
//produce type library (ComCaffe. TLB) and marshaling code,
Import "oaidl. Idl";
Import "ocidl. Idl";

CodePudding user response:
The IDL language does not support HC_VMT_NET_PlayErrorProc such function typeYou can use IDispatch to function like IE do a wrapper class, Invoke call your function,
