The Count property gets the number of lines in the control. The MultiLine property specifies whether the control accepts multiple lines. Use the InsertText method inserts text/lines to control. Use the InsertLockedText method inserts locked text/lines to control. Use the TextLine property to access the line based on its index. Use the Text property to access the control's text. Use the InsertText method to insert lines to the control. Use the DeleteLine method to delete a specific line.

The following VB sample prints the line in the control:

With CalcEdit1
    Dim i As Long
    For i = 1 To .Count
        Debug.Print .TextLine(i)
    Next
End With

The following C++ sample prints the line in the control:

for ( long i = 1; i <= m_edit.GetCount(); i++ )
	OutputDebugString( m_edit.GetTextLine( i ) );

The following VB.NET sample prints the line in the control:

With AxCalcEdit1
    Dim i As Integer
    For i = 1 To .Count
        Debug.WriteLine(.get_TextLine(i))
    Next
End With

The following C# sample prints the line in the control:

for (int i = 1; i <= axCalcEdit1.Count; i++)
	System.Diagnostics.Debug.WriteLine(axCalcEdit1.get_TextLine(i));

The following VFP sample prints the line in the control:

with thisform.CalcEdit1.Object
	local i
	for i = 1 to .Count
		wait window nowait .TextLine(i)
	next
