Hi
I'm new to IDL and I'm using 5.1 . I'm writing
an IDL wrapper for a bunch of c functions to
control some hardware. My problem is I haven't been
able to figure out how to get IDL to release
the dll after a run so that my compiler can write
a new version when I go back and make changes to the dll.
I end up being forced to close the IDL development
environment to get it to release after a call to
call_external. Here is my IDL code below, is there some kind
of 'dllclose' call to release d:\idlpvint\idlpvinterface.dll?
Thanks in advance....

lResult =
CALL_EXTERNAL('d:\idlpvint\idlpvinterface.dll','CaptureImage ',Image,w,h)
PRINT, "CaptureImage complete."
end
