The Registry.prg uses the winapi32 functions. As News2News defines, the string buffer is a DWORD (unsign 32bit). This is a maximum length. I can create a Key (TestMe) in the vfp9.0 registry section with a string length >256 (1000 bytes). When executing the Registry.prg function, the error occurs when the buffer is initialized to 256. Error stating that string would not fit in the buffer, and was truncated to the size of the buffer. Normally, if the resulting string is less then size of the buffer, the string is copied (plus a 0x00 terminator) to the buffer. The buffer itself will still be 256 bytes, but the string is zero terminated (this is a C thing) in the buffer. VFP only recognizes the returned string to either the zero terminator or the defined length of the buffer.

My guess is that when the Registry.prg was written, the system was 16bit. The thought of a string being over 256 was unheard of. But, now, in the new world, it it safe to have larger strings.

I added preprocessor declaration at the beginning of the file

#DEFINE REG_BUFFER_SIZE    4096

and replace all the 256 buffer size references to REG_BUFFER_SIZE.
