Chapter Eight — Data Functions (continued)
Overview
The FindInList function linearly scans a single-dimension array and attempts to match an entry based on specified metrics.
Syntax/Parameters
Syntax
int = FindInList ( string array[], string pattern, [int mode], [int start] );
int = FindInList ( int array[], long data, [int start] );
Parameters
array
An array of string or integer type data which must resolve to a single dimension. The integer type data can be up to 64 bits in width.
pattern
A string to search for within a string list (array). The array parameter must be a string type.
data
An integer value to search for within the list (array). The array parameter must resolve to an integer type. Either parameter can be up to 64 bits.
mode
An optional int specifying a match mode as defined below. The default is FIND_EXACT, which searches for an exact case-sensitive match. The mode codes are as follows:
| Term | Ordinal | Description | ||||
| FIND_EXACT | 0 | Match Exactly | ||||
| FIND_NO_CASE | 1 | Not Case-Sensitive | ||||
| FIND_WILD_CARD | 2 | Use Wild Card Matching | ||||
| FIND_WILD_CARD_NO_CASE | 3 | Use Wild Card Matching, No Case | ||||
| FIND_PARTIAL | 4 | Match Loosely/Partially | ||||
| FIND_PARTIAL_NO_CASE | 5 | Match Loosely/Partially, No Case |
This parameter may only be used with string searches. Use caution when using integer mode to not confuse the mode and start parameters since they are the same type. Do not use this parameter with integer data types.
start
An optional zero-based int specifying the starting search position.
Return Value
Returns an int specifying the matching index position or -1 if the item is not found. Use the GetLastError function to retrieve error information.
Remarks
The search range is from the optional specified starting position to the last element. Data from the last element to the allocated end of the array are not searched.
Since the return index can be -1 on error, it is imperative to check for an error prior to referencing the array with the returned value. The GetLastError function will return the error code ERROR_EOD if the item is not found.
For string searches, the FIND_PARTIAL and FIND_PARTIAL_NO_CASE modes look for the pattern inside the string entry. If it matches, the items is considered found.
For integer searches, use caution mixing types and signs since the compare is performed at a 64-bit level and negative items may not sign extend unless types match exactly.
Important: The mode parameter cannot be used with integer searches. Programmers should exercise care not to add a mode parameter which could be mistaken for the start parameter, thus resulting in unpredictable behavior.
