VBA - How to assign an object (from search) to a lookup property

Dear community,

I struggle to assign an object (that I retrieved through a search) to a property. This is basically what I am trying to do:

- I have a class with a property x (single select of object of type aaaa)
- I read the object of type aaaa with a search condition and I can successfully retrieve the object I want
- I do not really understand how to assign the retrieved object to the property x

Below the code I have written so far.

    ' create search condition
   oSearchCondition.ConditionType = MFilesAPI.MFConditionType.MFConditionTypeContains
   oSearchCondition.Expression.DataPropertyValuePropertyDef = Vault.PropertyDefOperations.GetPropertyDefIDByAlias("prop.Something")
   oSearchCondition.TypedValue.SetValue MFilesAPI.MFDataType.MFDatatypeText, "MY SEARCH TERM"
   
   ' Invoke the search operation.
   Dim oObjectVersions As New MFilesAPI.ObjectSearchResults
   Set oObjectVersions = Vault.ObjectSearchOperations.SearchForObjectsByCondition(oSearchCondition, False)
   
   ' --> this returns the object I want successfully.... (oObjectVersions(1))
   
   ' Creation of lookup object and assigning found object to it.
   Dim oLookup: Set oLookup = CreateObject("MFilesAPI.Lookup")
   oLookup.ObjectType = 115 ' ID of object type of retrieved object
   oLookup.Item = ???????????????? ' what to assign here??????????????? assigning oObjectVersions(1) wouldn't work because of wrong type..
   
   'Getting X property
   Dim objXProp As New MFilesAPI.PropertyValue
   Set objXProp = PropertyValues.SearchForPropertyByAlias(Vault, PROPDEF_X, True)
   objXProp.Value.SetValueToLookup oLookup

   
   'Target object CheckOut
   Dim oObjVersionACO
   Set oObjVersionACO = Vault.ObjectOperations.CheckOut(ObjID)

   Vault.ObjectPropertyOperations.SetProperty ObjVer, oLookup

   'Target object CheckIn
   Vault.ObjectOperations.CheckIn (oObjVersionACO.ObjVer)

Can somebody help for the line with the many question marks??

Many thanks,
Beat
