Creating File & Writing Data Causes a Permissions Error
I get a "permission denied" error while running the following code.
vb6 Code:
Public Function DeleteLines(ByVal from_name As String, ByVal to_name As String, ByVal target As String) As Long
Dim strlen As Integer
Dim from_file As Integer
Dim to_file As Integer
Dim one_line As String
Dim deleted As Integer
' Open the input file.
from_file = FreeFile
Open from_name For Input As from_file
' Open the output file.
to_file = FreeFile
Open to_name For Output As to_file
' Copy the file skipping lines containing the
' target.
deleted = 0
Do While Not EOF(from_file)
Line Input #from_file, one_line
If InStr(one_line, target) = 0 Then
Print #to_file, one_line
Else
deleted = deleted + 1
End If
Loop
' Close the files.
Close from_file
Close to_file
Kill (from_name)
Name to_name As from_name
DeleteLines = deleted
End Function
It happens on Print #to_file, one_line. Something must have changed, because it was working fine before. But I don't see anything that could've affected this. So just for clarifiction: the code creates a new file from target. This is working correctly. Then it's supposed to copy the lines from the old file (from_name) to the new file and then deletes the old file. The copying part is where it's failing.
Thanks
Re: Creating File & Writing Data Causes a Permissions Error
A file permission error may have nothing to do with your code, but rather where you are trying to write the file. On modern Windows operating systems, many directories have read-only permissions. For example, by default the "Program Files" directory does not have write permissions. The individual users directories however, do have write permission. This is all part of a deliberate effort on the part of Microsoft to protect one user from another.

On windows Vista or better, "My Documents" does not actually exist. Go to the command prompt and enter the following command in your user directory:
C:\Users\UserID>dir /a
There you will see "My Documents" listed as a junction:
01/12/08 08:27 PM <JUNCTION> My Documents [C:\Users\UserID\Documents]
The real name of the directory is listed as just "Documents".

I would appreciate it if you could provide any information that is relevant. This has nothing to do with what I'm asking.
Re: Creating File & Writing Data Causes a Permissions Error
I was mistaken on when the error occurs. It seems as if it executes Do While Not, Line Input #from_file, one_line, and If InStr(one_line, target) = 0 Then just fine. Then it loops back up to Do While Not EOF(from_file) and errors out there.
Re: Creating File & Writing Data Causes a Permissions Error
Ugh... this whole thing is a mess. For some reason, the line where I compare the string (Instr) was changed from > 0 to = 0. I changed it back so that's working again. But it looks like it is failing on where I'm trying to delete from name via Kill (from_name). I'm closing the file prior to that point, so I'm not sure why I'm being denied.
