>OK, second attempt. The function I need access to is GetCurrentHwProfile, which uses the HW_PROFILE_INFO structure. I have downloaded Cristof Lange's struct.vcx, and it appears what I want is doable. However, I will admit that I am way over my head here. Can anyone provide a VFP translation for me?

Jim,
Because all parts of the structure are fixed length, you don't really need Struct or Ed Rauh's CLSHEAP classes. You can pass the function a string.

declare integer GetCurrentHwProfile in advapi32 string@
declare integer GetLastError in kernel32
lcdocked = chr(1)+replicate(chr(0),3)  && equates to desktop computers (always docked)
lcguid = replicate(chr(0),39)  && room for GUID identifier along with brackets and null terminator
lcname = replicate(chr(0),80)  && room for name of profile (80 character limit)
lcstruct = lcdocked+lcguid+lcname
if GetCurrentHwProfile(@lcstruct) <> 0 then
  * it worked
  ? substr(lcstruct,4,39)  && prints GUID identifier
  ? substr(lcstruct,44,80) && prints name of profile with trailing null terminiators (you can trim these using at() to find first occurrence)
else
  ? GetLastError()
endif

HTH.
