How to wrie to file in Append mode? 1

[John59]

Hi everybody!
Could you advice me briefly (or provide an example) how to use Append mode while writing to file?

Thank you in advance..

This will add a line to the end of the file.

Open "C:\Temp\SomeFile.txt" For Append As #1
    Print #1, "Just Added This Line"
Close #1

Thanks for hint!
The next question will be: how open his file again and to append second line to its end? Have I to repeat Open ... as it was at beginning?

John:

You can append as many lines as you want.

'Example 1
Open "C:\Temp\SomeFile.txt" For Append As #1
    Print #1, "Just Added This Line"
    Print #1, "Just Added This Line Too"
Close #1

'Example 2
Open "C:\Temp\SomeFile.txt" For Append As #1
    Print #1, "Just Added This Line"
Close #1
Open "C:\Temp\SomeFile.txt" For Append As #1
    Print #1, "Just Added This Line Too"
Close #1

'Example 3
Open "C:\Temp\SomeFile.txt" For Append As #1
    For i = 1 to 10
        Print #1, "Just Added This Line: " & i
    Next i
Close #1

Once the file is Open, you can add lines, perform other tasks, add more lines and so on. Once you Close the file, you will have to open it again to write to the file. DimensionalSolutions@Core.com

Thanks!
The reason for that question was to estimate possibility to use such a writing for round-the-clock measurements with 30 seconds interval. In that case the open/close sequence will prevent data loss in a case PC hang-up. Unfortunately there are not any examples about Append mode in MSDN.

Thanks again!
