Pocket PC Forum / End Users / ActiveSync / August 2006RAPI CeGetDiskFreeSpaceEx with WM2003
When calling the RAPI function CeGetDiskFreeSpaceEx("\Program Files", ...) in WM2005, it works fine, returning correct values. Calling the same function when a WM2003 device or WM2003 emulator is attached fails. I.e the return value is 0. Looking at the documentation... Requirements Pocket PC: Pocket PC 2000 and later Smartphone: Smartphone 2002 and later OS Versions: Windows CE 3.0 and later Header: Rapi.h ... I would expect it to work. Does anyone know why this does not work with a WM2003 device? Thanks Wade See, GetLastError()  Signature40th Floor - Software @ http://40th.com/ iPlay : the ultimate audio player for mobiles mp3,mp4,m4a,aac,ogg,wma,flac,wav, play+record parametric eq, xfeed, reverb; all on a mobile GetLastEror returns 0 Perhaps your comment should have referred to "CeGetLastError" CeGetLastError returns 120. Error 120 is ERROR_CALL_NOT_IMPLEMENTED, This function is not valid on this platform. Which takes back to my original question. The documentation clearly indicates that CeGetDiskFreeSpaceEx is available on a variety of CE versions, but on WM2003 it fails. Anyone have any ideas why? >See, GetLastError() At least that got you going. Here's a real old note I found File: ...\40ce2\arm\cesupp_old.cpp 182: // nts: calls GetDiskFreeSpaceEx(), since there is no CeGetDiskFreeSpaceEx() RAPI version which is from a routine in a DLL I (have to) (rapi) invoke. Since that goes back more than 4 years, the docs have been wrong for a while (or the code never caught up). CeGetStoreInformation() get the object store info. That's all you get to rapi with.
