Returns the letters used for RC style addresses
static BOOL GetRowColumnLetters( char& chRow, char& chColumn, BOOL bLocalLanguage ); static BOOL GetRowColumnLetters( wchar_t& chRow, wchar_t& chColumn, BOOL bLocalLanguage );
If successful, will contain the letter used for rows in RC-style addresses.
If successful, will contain the letter used for columns in RC-style addresses.
TRUE if the letters are for the local language; FALSE for English. R1C1 format addresses use different letters in different languages: thus the English address "R1C2" is written as "Z1S2" in German. If bLocalLanguage is TRUE, then the local letters are returned; if bLocalLanguage is FALSE, then the results are always "R" and "C".
TRUE if the letters are found; FALSE otherwise.
If bLocalLanguage is TRUE, this function can only be called from macro functions, or from worksheet functions that have been marked as "Defer recalculation". It will always fail if called from worksheet functions that have not been marked as "Defer recalculation", if bLocalLanguage is TRUE.
