Applies To: Microsoft Dynamics AX 2012 R2, Microsoft Dynamics AX 2012 Feature Pack, Microsoft Dynamics AX 2012

Searches a text string for an occurrence of another string.

int strScan(
    str _text1,
    str _text2,
    int _position,
    int _number)

Parameters

Parameter

Description

_text1

The string in which to search.

_text2

The string to find.

_position

The first position in the _text1 parameter to perform a comparison.

_number

The number of positions in the _text1 parameter for which to retry the comparison.

If there is a minus sign in front of the _number parameter, the system searches the number of characters in reverse order from the specified position.

Return Value

The position in the string at which the specified string was found; otherwise, 0.

Remarks

The comparisons are not case sensitive.

Values for the _position parameter that are less than 1 are treated as 1.

The direction of the scan is controlled by the sign specified in the _number parameter. A positive sign indicates that each successive comparison will start one position closer to the end of the string. A negative sign indicates that each comparison will start one position closer to the start of the string.

  • strScan("ABCDEFGHIJ","DEF",1,10); //Returns the value 4.

  • strScan ("ABCDEFGHIJ","CDE",10,-10); //Returns the value 3.
