With wich API call can I get the "Open With" dialog started that usually
shows up when you double click a file with a file extension that isn't
associated with a program?

Thanks in Advance
Harry

The call is as follows:
%SystemRoot%\system32\rundll32.exe
%SystemRoot%\system32\shell32.dll,OpenAs_RunDLL %1

%SystemRoot% is your windows directory
%1 is the file you wish to open

If you find out any other calls to the shell32.dll, let me know.

thx,
JAW
