Hi, for some of my Scripts i need a function to change some file properties. I have downloaded a .dll file from Microsoft with the function i need. Now my problem: It is a COM function. How can i call it without the need, to register the dll? Is it possible? I tried to translate some VB code (only working with registered DLL): Set oFile = CreateObject("DSOFile.OleDocumentProperties") oFile.Open("c:\tmp\test.txt") oFile.SummaryProperties.Comments = "Test Comment" oFile.Save oFile.Close
