Using version 6.22 and happy to upgrade but I only see an upgrade to version 6.xx on the site. Can't figure out why it can't find it. I did check all paths for wwapi and it is added as follows.

#INCLUDE r:\programs\wwipstuff622\WCONNECT.h
SET SAFETY off
set safety off
set deleted on
SET REPROCESS TO AUTOMATIC
set date to short
set century on
SET DEFAULT TO r:\programs\chrobinson
SET CPDIALOG OFF
SET NULLDISPLAY TO ""

*#DEFINE VFP6

SET PROCEDURE TO r:\programs\wwipstuff622\classes\wwUtils ADDITIVE
SET PROCEDURE TO r:\programs\wwipstuff622\classes\wwHTTP ADDITIVE

DO r:\programs\wwipstuff622\classes\wwdotnetbridge

loBridge = GetwwDotnetBridge("V4")

InitializeDotnetVersion("V4")

loHTTP=CREATEOBJECT("wwHTTP")

Thanks Ricky

It's in wwAPI.prg. It's a plain function not a class.

DO wwapi
? HashMd5("Hello World")               && binary 
? STRCONV(HashMd5("Hello World"),13)   && Base64
