IID_IUnknown above refers to the object is not my OCX, be OLEXXX system, causes the ppIface get behind me is not my OCX interface pointer, I use MyOcxFaceID instead of no use, I use the OLE - the VIEW I checked the OCX,

excuse me, what the hell is going on this back, I want to get my OCX virtual table

CodePudding user response:

Look at the registration table corresponding clsids below the factory information is correct

CodePudding user response:

Use the # import, then use smart Pointers

CodePudding user response:

reference 1/f, jiangsheng response:

see registries corresponding clsids factory information below is correct

TypeLib: {d1 c7d B26F6243-4-11-910 - e - 00600807163 - f}
ProgID: XCEEDZIP. XceedZipCtrl. 1
These should be yes
Class ID is definitely yes
Path is also correct C: \ Windows \ SysWow64 \ XCDZIP35 OCX

refer to the second floor worldy response:

use # import, and then use the smart pointer

Tried, as also

Why are two not MyOcxFaceID

this is to call back after the IID
