Comments

The DTWAIN_RangeGetExpValueFloatString works the same as DTWAIN_RangeGetExpValueFloat with the difference that the floating point value is returned in string form to lpValue.

This function can be used by computer languages that do not handle 64-bit IEEE parameters correctly. The string buffers (if they are not NULL) must be sized to at least 255 characters.

TWAIN State Transitions

None.
