If I use Reg.ReadString method on a REG_EXPAND_SZ item which I have found in the user settings in the registry for CVSNT I get back a string looking like this: C:\Programs\cvsnt\cvsnt-default.pem But if I export the registry key with RegEdit I get this instead: "CertificateFile"=hex(2):43,00,3a,00,5c,00,50,00,72,00,6f,00,67,00,72,00,61,00,\ 6d,00,73,00,5c,00,63,00,76,00,73,00,6e,00,74,00,5c,00,63,00,76,00,73,00,6e,\ 00,74,00,2d,00,64,00,65,00,66,00,61,00,75,00,6c,00,74,00,2e,00,70,00,65,00,\ 6d,00,00,00 It looks like the data is encoded with 16 bit values per character and stored in successive 1-byte hex values with lsb first, but is this always the case and why does the ReadString function not deliver the hex in that case. Can someone explain how it works? And why there is no TRegistry class method for fetching the REG_EXPAND_SZ data type? Does it have something to do with Unicode on Windows (I am testing on a Windows 7 Pro X64 machine)? -- Bo Berglund Developer in Sweden -- _______________________________________________ Lazarus mailing list Lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus
