use the /dropfile command...
and then if you wants to do more just use the # to split up and do more commands as it says in the Sample... that is if you use VB I don't know about the c/c++ side of this story but I guess that you can use the same plus commands...
...
Eg. (I'm not sure this works, just making this as I write, but it should work)
sResult = "#/dropfile c:\fun.jpg" & vblf & "#Check this out!!!"
