Michel,

When a component is installed it's interface is cast in stone as far as MTS is concerned. If you change the interface (add/remove) a public property or method, you need to remove the component and reinstall it.

If you don't change the interface you can just simply copy the dll over the old dll as long as there are no instances of the dll currently running on the server.

>I will try to uninstall but this is very special. If I remove the property the dll I generate work if I had a property again the dll fail. The method call is prepxml and at the fist line the methode receive a path. Just the next line I put a strtofile whit the path and a dash before. When the dll work I file text.txt is created with the path (- c:\temp\_x9d7fjsd\). If I had a property the file text.txt is not created and I receive an error from this method at line 30. At this line we try to create an xml using this path.
