You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: oleutil.go
    path of file: ./repos/bzppx-codepub/vendor/github.com/go-ole/go-ole/oleutil
    
    the code of the file until where you have to start completion: package oleutil

import ole "github.com/go-ole/go-ole"

// ClassIDFrom retrieves class ID whether given is program ID or application string.
func Cl
    
func MustGetProperty(disp *ole.IDispatch, name string, params ...interface{}) (result *ole.VARIANT) {
	r, err := GetProperty(disp, name, params...)
	if err != nil {
		panic(err.Error())
	}
	return r
}
