Hi

I'm wondering if there is any way to determine if there is a program installed that can handle a given file type and they use it to open a given document.

E.g I want to be able to execute a PDF or a DXW file from within my vbNet application but only if a PDF or DXW viewer is installed and registiered otherwise I want to trap the fact that a handler isn't installed and bring up a message box.

Thanks,

Sarah
