Thanks for your reply I try to remove component from component service and add this component after I add my new property. Nothing change.

Here my code from asp
-----
function ConstMesg()
lcPathXMl = session("repXML")
Set oPopMsgCrit = server.CreateObject("SiteBssfd.commun")
lcRetErr = oPopMsgCrit.PrepMessage(lcPathXMl)
-----------
Here my code from the class SiteBssfd.commun proc PrepMessage

PARAMETERS pPathXML

LOCAL lcNomTable, lcPathDBFMess

lcPathDBFMess = this.oUtil.CreerPathTemp() && Path temp pour dbf

=this.oTable.ouvTabNom("sb_type_mesg","","NOUP")
=this.oTable.ouvTabNom("sb_message","","NOUP")

SELECT sb_type_mesg
SCAN
lcID_type = sb_type_mesg.id_type

SELECT * ;
from sb_message ;
WHERE id_type == lcID_type AND between(datetime(),dt_debut,dt_fin) ;
order by dt_debut desc;
INTO TABLE (lcPathDBFMess+"tmp_message.dbf")

=CURSORTOXML("tmp_message",pPathXML + "sb_Message_" + ALLTRIM(STR(lcID_type)) + "XML.xml",3,512)

The parameter pPathXML is empty when I add a property in my class and I try to put a strtofile to check the path and I add some other character like ---. When the class dont have a new property the strtofile work fine and when I had my property the strtofile give nothing, even if the parameter is empty this is suppose to give the character ----. Finally the code crash when he try to do =CURSORTOXML using the path. I did IIS reset and restart the server. Also I try to make a new project, put all the stuff in and recompile my dll.

>>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.
