Method

TextEdit.AppendText(text as String)

Supported for all project types and targets.

Appends the passed text to the current Text. Call AppendText rather than using the + operator to append text to existing text.

Example

This example reads a text field in blocks of 1000 characters using Read.

Dim f As FolderItem
Dim dlg As OpenDialog
Dim t As TextInputStream

// create a new openDialog
dlg = New OpenDialog
// set what type of file it looks for
dlg.Filter = "text/plain"

// run the dialog
f = dlg.ShowModal

// check to make sure the user didn't click cancel
If f <> Nil Then
t = TextInputStream.Open(f)
// make sure we could open it
If t <> Nil Then
// Read all of the text, 1000 characters at a time
// into the TextField
While Not t.EOF
myTextArea.AppendText(t.Read(1000, Encodings.UTF8))
Wend

t.Close
Else
// the file could not be a read as a text file
MsgBox("The selected file is not a text file. Error: " + Str(t.LastErrorCode))
End If
Else
// the user clicked cancel... just ignore it
End If
