How can fso tell if a txt is empty in asp?

whichfile="")

set fso = createobject("")set txt = ,1)

while not

rline ='Read a row.

if left(rline,1)='a' thenb=split(rline," ",-1,1)'Use a space to truncate the ordinal number aa=b(1).

bb=b(3)

cc=b(5)

dd=b(7)

else changdu=len(rline)'Determine the length of a row a=split(rline," ",-1,1)'Use a space to truncate the ordinal id=trim(a(0)).'Use a space to truncate the ordinal number changdu2=len(id).'Length of serial number question=mid(rline,changdu2,changdu-changdu1-1).'Screenshot the question.

answer=right(rline,1)end if

sql="insert into "& Table.

Check whether the file size is 0

The paragraph on the previous page is written in the loop.

set fs ="") 'Create an FSO object entity with the server and assign it to the FS

set a = ""), true) 'Use the createtextfile method of fs to create a text file and assign it to a

Write a line of text to the created text file A using the writeline method.

Close the A-file.

You can read out the entire contents of the file first, and then put the data you want to write in front of or after the readout content, combine it into a large string, and then write it to the original file in overwrite mode all at once. For example:

'First, read the contents of the txt file through the FSO component, extract the user name, and assign a value to the variable un'Since you don't know the structure of your txt file, you can't give a specific **if un=username then

The username matches! "

The username doesn't match! "

end if

You work with the fso to read the contents of the txt file, and then use spilt to filter it.

Pay attention to the encoding of the file,,And the BOM header,,If the encoding is different,There will be garbled characters,,If there is a txt of the BOM header,,ASP will also appear garbled when read out。。。
