Remarks

AdsGetField can be used to retrieve string, numeric, date, logical, double, CurDouble, Money, integer, short date, time, timestamp, memo, image, RowVersion, ModTime, and binary data. For numerics, Money, times, timestamps, and dates, it converts the result to a string (instead of storing the IEEE numeric data in the buffer). Dates are formatted according to the date mask set by AdsSetDateFormat. If AdsGetField returns AE_INSUFFICIENT_BUFFER, the number of bytes needed for the call to succeed is returned in the pulLen parameter.

The pucFldName parameter can be passed as the field name itself or as the one-based integer field position. To pass an integer field position for the pucFldName parameter, use the ADSFIELD macro that is defined in ACE.H. For example, to specify the first field in the table, pass ADSFIELD(1) for the pucFldName parameter; to specify the second field in the table, pass ADSFIELD(2) for the pucFldName parameter; etc.
