Thank you sir ... but this is old news, I have tried the diffenent codesnippets back and forth and now the problem isn´t the code. It is the WSE and DIME, and why I can´t make that work. I have uninstalled the WSE and reinstalled it (WSE 2.0) and still it points on WSE 1.0, I get an errormessage when I run it in the Fusion Log "File or assembly name Mirosoft.Web.Services or one of its dependencies, was not found." Do I need to make any changes in a config-file? I have tried changes in both web.config and machine.config, but I can´t get it to work. With the highest regards:) // Daniel
