If your operating system language is other than English, you may need to change the decimal number separator in your regional setting from comma to point. To do so, please select Settings/System/Regional Settings/Number/Digit grouping symbol.

En Francaise: Pour resoudre le probleme de type mismatch, aller dans Parametres, onglet Systeme puis Parametres regionaux, choisir un autre type de profil, par defaut Francais (standard), utiliser Anglais (Irlande) ou n'importe quel autre profil utilisant la virgule a la place du point comme symbole decimal. Vous pouvez egalement simplement changer le simbole decimal dans l'onglet Nombre en remplacant la virgule par le point.

Auf Deutsch: Ländereinstellungen, die ein Komma als Dezimaltrennung einsetzen können zu Fehlverhalten des Programms führen. Bitte sind Sie daher so gut und setzen die Dezimaltrennung auf Punkt in Settings/System/Regional Settings/Number/Digit grouping symbol, wie auch immer das auf Deutsch übersetzt wird.

SOLAR SYSTEM OBJECTS CAN GET CLOSE TO THE SUN DURING THE PERIOD COVERED IN THE EPHEMERIS COMPUTED BY TAIYOUKEI. OBSERVERS ARE WARNED TO BE WARY OF OBSERVING ANY OBJECT NEAR THE SUN. NEVER POINT ANY KIND OF OPTICAL INSTRUMENT AT THE SUN--INSTANT BLINDNESS WILL BE THE MOST PROBABLE RESULT.

Taiyoukei is "RobinHoodWare", in other words, the rich donate for the poor. Embedded VB programmers without emulator will envision the amount of work and time invested in this application. If you can afford a donation please support the work, if you really can't, just enjoy and feed back your findings.

Taiyoukei will be posted for free download for a couple of months. If it does not return the investment with donations... what would you do?
