// - Changed name_ in Style from SmallString to LargeString.
|
// - Fixed bug in BasicExcelCell::GetString and BasicExcelCell::GetWString.
|
// - Minor changes to functions in BasicExcel and BasicExcelWorksheet which checks for unicode.
|
// - Minor change to SmallString::Read.
|
// Version 1.10 (30 May 2006)

// - Changed BasicExcelCell::Get() so that it will get a stored double as an integer or vice versa if necessary.
|
// - Changed BasicExcelCell::Get() so that it will not cause any errors if a string is empty.
|
// - Changed BasicExcelCell::SetString() and BasicExcelCell::SetWString() so that it will not save an empty string.
