String Functions

InstallShield 2015 » InstallScript Language Reference

The string functions provide the ability to manipulate string variables and literals. String functions behave similarly to the standard C language functions. The return values also follow the C language convention.

String Functions
Function	Description
CopyBytes	Copies a specified number of bytes from one string to another.
GetCArrayFromISArray	Returns a pointer to an array of pointers that point to the actual data of the specified array. This function does not allocate any additional memory, but it returns a pointer to the data in the existing array.
GetCHARArrayFromISStringArray	Returns a pointer to an array of pointers to ANSI character strings that corresponds to the wide character strings that are contained in the specified array.
GetDir	Deletes the drive designation from a path or fully qualified file name.
GetDisk	Retrieves the disk drive designation from a path or fully qualified file name.
NumToStr	Converts a number to a string.
ParsePath	Retrieves the drive, path, file name, or extension from a path.

StrCompare	Compares one string to another.
StrConvertSizeUnit	Returns the appropriate display string for the InstallScript size unit constant that is specified.
StrFind	Finds a string in another string.

StrGetTokens	Gets a token from a string based on specified delimiters.
StrLength	Like StrLengthChars, returns the number of characters in a given string variable (that is, the number of code units in the UTF-16-encoded string) up to the first null character.
StrLengthChars	Like StrLength, returns the number of characters in a given string variable (that is, the number of code units in the UTF-16-encoded string) up to the first null character.
StrPutTokens	Extracts list items from a specified string list and places them into the string that is specified by svString.
StrRemoveLastSlash	Removes the last backslash in a path string.
StrReplace	Searches svResult, beginning at the location specified by nStart, and replaces all found instances of szFind with szReplace.
StrSub	Returns a substring from a string.
STRTOCHAR	Returns the first character of a string as data of type CHAR.
StrToLower	Converts all alphabetic characters in string to lowercase.
StrToNum	Converts a string to a number.
