The problem is here:

Code: Select all

file = io.open("A.txt","r")

File paths in Lua are not automatically relative to the skin folder, the way regular path options in Rainmeter are. You'll need to specify the location explicitly. We added a built-in MakePathAbsolute function to do this. Example:

Code: Select all

FilePath = SKIN:MakePathAbsolute('A.txt')
file = io.open(FilePath, 'r')

Or, if you really want to be compact:

Code: Select all

file = io.open(SKIN:MakePathAbsolute('A.txt'), 'r')

it 's ok now~ thank you ~

but why it still doesn't work when i use a complete path as,

"D:\DATA\Rainmeter\skin\A.txt" ?

the "\" character is reserved in Lua as an "escape" character, so you would need "D:\\DATA\\Rainmeter\\skin\\A.txt"
