Using Visual C++ 2010 in XP and WINVER=0x500, find / replace dialogs do not work (the commands just fail silently). As an alternative, we can load kernel32.dll and bind the memory address of MemoryStatusEx. If it isn't found, then fallback to MemoryStatus, thus eliminating the requirement of changing WINVER. -- You received this message from the "vim_dev" maillist. Do not top-post!
