The Select method selects the text or sets the cursor position for the associated edit control. If the starting index equals the ending index, no text is selected and the cursor is set to the character at the specified index. If the ending index is 0 and the starting index is 1, the entire text is selected.
The arguments are:
A one-based index where the selection begins or the cursor is to be set.
A one-based index where the selection ends.
