Vba to append a text file I have a.ADP file that uses VBA to import a file to a 'staging' file and then appends the staged file into an SQL table. This has worked for about 2 years without a problem. Write text, csv and binary files to strings using VBA. How to write files VBA in Excel and Access. Write file VBA. Visual Basic 1. To Append to the text file instead of overwriting replace For Output with For Append in the Open fileName For Output As #fileNo. Approach #2: The Print function (dumping strings without quotes).
The WriteAllText method can be used to append to a text file by specifying that the
append
parameter is set to True
.To append to a text file
- Use the
WriteAllText

Robust Programming
The following conditions may cause an exception:
- The path is not valid for one of the following reasons: it is a zero-length string, it contains only white space, it contains invalid characters, or it is a device path (starts with .) (ArgumentException).
- The path is not valid because it is
Nothing
(ArgumentNullException). File
points to a path that does not exist (FileNotFoundException or DirectoryNotFoundException).- The file is in use by another process, or an I/O error occurs (IOException).
- The path exceeds the system-defined maximum length (PathTooLongException).
- A file or directory name in the path contains a colon (:) or is in an invalid format (NotSupportedException).
- The user lacks necessary permissions to view the path (SecurityException).

Hi
I'm using the following code to append a text file:
Dim sw As IO.TextWriter
sw = IO.File.AppendText('C:MyTextFile.txt')
sw.WriteLine(text1.text)
sw.Flush()
sw.Close()
sw = IO.File.AppendText('C:MyTextFile.txt')
sw.WriteLine(text1.text)
sw.Flush()
sw.Close()
For some reason this is the output:

Are you saying that you have a bunch of lines that added in succesion instead of one line?
Try using the StreamWriter class. I have used it on a number of occassions to write text to a file and I have had no problems.
