Hi,

To access a peripheral I need to provide AccessCode and ShareMode. The
values for AccessMode, per MSDN docs, are 0, GENERIC_READ, and
GENERIC_WRITE. For ShareMode, they are FILE_SHARE_READ and
FILE_SHARE_WRITE. If I want to read and write I would need to OR the
values. However, VS2005 does not recognize them as defined values. I
was thinking if I can find the Hex values for them then I can just pass
the hex values in the function call. If someone could tell me what
these values are or where can I find them is appreciated. Thanks.

Cheers,

Mario
 
You'd find them in a C/C++ SDK for the target device or at least for a
device like it. Since you're using VS2005, the header files for the target
device and C/C++ should be there (<x>:\program files\Microsoft Visual Studio
8\SmartDevices\SDK. Search for files like *.h containing those strings and,
no, don't just use hex values. That makes your code very annoying to read.

Thanks Paul. I did find the hex values. However, I found them under
PocketPC2003 and SmartPhone2003. Does that mean that I am missing the
SDK for WinCE? My project is on WinCE. Thanks.

No, that's fine. The values don't change from one version to another. I'm
sure that you won't find the C/C++ SDK for your Windows CE device in that
folder. If you figure out where you installed it, probably \program
files\windows ce tools\wce500\<platform name>, you'll find the same values
there.

Thanks. This is really helpful.
