FindInString Function

Overview

The FindInString function scans a string for a target string and returns its position. The function has options to begin its search from a specific location, specify case sensitivity or to search in look back mode.

Syntax/Parameters

Syntax

int = FindInString ( string source, string match, [int position, [dword flags]] );

int = FindInString ( wstring source, wstring match, [int position, [dword flags]] );

Parameters

source

A string or wstring to search.

match

A string or wstring to find within the source. The match parameter must match the source parameter type.

position

An optional int containing a zero-based starting position. By default, the search begins at the start of the string (position = 0).

flags

An optional dword to specify options:

TRUE  = case-sensitive

FALSE = case-insensitive

By default, the search is case-insensitive. See remarks for additional flags.

Return Value

Returns an int containing the zero-based starting position within source where match was found or -1 on an error. Use the GetLastError function to retrieve error information.

Remarks

Unlike the InString function, the FindInString functions offers greater control over the search mechanics. Specifically, it permits a starting search position and case-sensitivity to be specified. However, this function does not allow searching for a specific character, which makes it a less ideal tool for finding white space, word space, or other special characters within a string. A boolean version of this function is available as the IsInString function.

If match is not found within source, the GetLastError function will return ERROR_EOD. If the position is outside the length of source, the GetLastError function will return ERROR_RANGE.

The flags parameter specifies two options:

FIS_NOT_CASE_SENSITIVE  0x00000000   Find without Case Sensitivity, same as FALSE, default

FIS_CASE_SENSITIVE      0x00000001   Find with Case Sensitivity

FIS_LOOK_BACK           0x00010000   Scan Backwards (reverse)

Case-insensitive matching is performed on a locale basis as set by Windows. For US, on ASCII matching is the only case matching performed.

Related Functions

CompareStringsNoCase — Compares string a to string b without regard to text case and returns 0 if equal, -1 if a < b and 1 if a > b.

IsInString — Checks for a string or character matching inside a target string.

IsRegexMatch — Performs a regular expression pattern match on string data.

InString — Tests for a string as part of a target string with or without case sensitivity.

ReplaceStringSegment — Replaces a specified segment within a string with another string.

ScanString — Scans a string as a list delimited by spaces, commas or line endings.
