readable size REG_EXPAND_SZ??

ShakerWD · 31st August 2005, 10:03

hi,
whats the readable size of an REG_EXPAND_SZ with ReadRegStr?
need to read and write HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ DevicePath

on my system there are 2062 characters in this string.
ReadRegString fails and returns "". Adding a test Key with the same type and 15 characters works fine.

solutions for this?

cheers

Daniel

For read such string you need to use NSIS special build with max string length 8192:
http://sourceforge.net/project/showf...ckage_id=15374

And if you want to use registry plugin with this special build for read strings more then 1024 you need to recompile it with line:

code:
#define MAX_STRLEN 8192
