Comments

DTWAIN_ArrayGetAtFloatString works the same way as DTWAIN_ArrayGetAtFloat, with the difference being that the floating point value is returned as a string in the string buffer pValue.

This function is useful if the computer language used to write your application doesn't use or handle DTWAIN_FLOAT variable types correctly, and you want to call DTWAIN functions that use DTWAIN_FLOAT values.

TWAIN State Transitions

None.
