|(Declarations)||Declarations||Declarations and private variables for the CFuzzyStringSearch class.|
|CaseSensitive||Property||Determine whether or not the search is case sensitive. This property must be set before the FindText and Text properties.|
|FindText||Property||Get the search text.|
|MaxCharacterDifference||Property||Get the maximum number of different characters allowed for a match.|
|Text||Property||Get the text that is being searched.|
|Class_Initialize||Initialize||Set initial values to defaults which may be overridden with property settings.|
|FindNext||Method||Finds the next matching string. This function increments the index into the search buffer each time it is called. To begin searching from the beginning of the search buffer, call the Reset method.|
