vb.net trim 和vb trim 的区别
代码大致
declare function GetPrivateProfileString lib "kernel32" alias "GetPrivateProfileStringA" (a as string,b as string,c as string,d as string,e as integer, f as string) as integer
buff = len(300)
call GetPrivateProfileString(a,b,"",buff,d,e)
len(trim(buff))
vb 字符串的实际长度
vb.net 301
