Use a MouseDown or MouseUp event procedure to specify actions that will occur when a mouse button is pressed or released. Unlike the Click and DblClick events, MouseDown and MouseUp events lets you distinguish between the left, right, and middle mouse buttons. You can also write code for mouse-keyboard combinations that use the SHIFT, CTRL, and ALT keyboard modifiers. Use the ClientToCursor method to convert client coordinates to cursor coordinates. Use the TextLine property to get the line giving its index.

The following VB sample displays the line from the cursor:

Private Sub Edit1_MouseUp(Button As Integer, Shift As Integer, x As Single, y As Single)
    With Edit1
        Dim i As Long, c As Long
        .ClientToCursor x / Screen.TwipsPerPixelX, y / Screen.TwipsPerPixelY, c, i
        If (i > 0) Then
            Debug.Print .TextLine(i)
        End If
    End With
End Sub

The following C++ sample displays the line from the cursor:

void OnMouseUpEdit1(short Button, short Shift, long X, long Y) 
{
	long nLine = 0, nColumn = 0;
	m_edit.ClientToCursor( X, Y, &nColumn, &nLine );
	if ( nLine > 0 )
		OutputDebugString( m_edit.GetTextLine( nLine ) );
}

The following VB.NET sample displays the line from the cursor:

Private Sub AxEdit1_MouseUpEvent(ByVal sender As Object, ByVal e As AxEXEDITLib._IEditEvents_MouseUpEvent) Handles AxEdit1.MouseUpEvent
    With AxEdit1
        Dim i As Integer, c As Integer

        If (i > 0) Then
            Debug.WriteLine(.get_TextLine(i))
        End If
    End With
End Sub

The following C# sample displays the line from the cursor:

private void axEdit1_MouseUpEvent(object sender, AxEXEDITLib._IEditEvents_MouseUpEvent e)
{
	int iLine = 0, iColumn = 0;
	axEdit1.ClientToCursor(e.x, e.y, out iColumn, out iLine);
	if (iLine > 0)
		System.Diagnostics.Debug.WriteLine(axEdit1.get_TextLine(iLine));
}

The following VFP sample displays the line from the cursor:
