open file and appending from end of file in API

[daylor]

hi.

how can i open file in api(this i know..) AND

start writing text from the END of the file...

'Read

Open "C:\TxtFile.txt" For Input As #1
Text1.Text = Input$(LOF(1), 1)
Close #1

'Save

Open "C:\TxtFile.txt" For Output As #1
Print #1, "Your text here"
Close #1

If you want to save the files and keep everything rather than overwriting it.
Which I believe is what you want to do:

Open "C:\TxtFile.txt" For Append As #1
Print #1, "Your text here"
Close #1

That's not an API method though. If you want to stick to pure API, use WriteFile.
