DTWAIN_ArrayFindFloatString

DTWAIN_ArrayFindFloatStringA

DTWAIN_ArrayFindFloatStringW

The DTWAIN_ArrayFindFloatString function searches for a DTWAIN_FLOAT value in a DTWAIN_ARRAY.

LONG DTWAIN_ArrayFindFloat (

DTWAIN_ARRAY	Array,
LPCTSTR	Value,
LPCTSTR	Tolerance );

Parameters

Array

DTWAIN_ARRAY to search.

Value

value to search for

Tolerance

Tolerance level to use when determining equality.

Return Values

If the function succeeds, the zero-based position of the element is returned.

On failure, a -1 is returned if the element cannot be found, or another error has been encountered. Call DTWAIN_GetLastError() to get extended information.

Character specific version

ANSI version:	DTWAIN_ArrayFindFloatStringA
Unicode version:	DTWAIN_ArrayFindFloatStringW

Comments

DTWAIN_ArrayFindFloatString works the same way as DTWAIN_ArrayFindFloat, with the difference being that Value and Tolerance are string versions of the DTWAIN_FLOAT value, i.e. "65.7" instead of 65.7.

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.
