StringBuilder ActiveX Reference Documentation

StringBuilder

Current Version: 9.5.0.72

A simple class for building strings. (Represents a mutable string of characters.)

Note: This class was introduced in Chilkat v9.5.0.58.

Object Creation

(Visual Basic 6.0)
Dim obj As New ChilkatStringBuilder

(ASP)
set obj = Server.CreateObject("Chilkat_9_5_0.StringBuilder")

(VBScript)
set obj = CreateObject("Chilkat_9_5_0.StringBuilder")

(Delphi)
obj := TChilkatStringBuilder.Create(Self);

(FoxPro)
loObject = CreateObject('Chilkat_9_5_0.StringBuilder')

(PowerBuilder)
lole_object = create oleobject
li_rc = lole_object.ConnectToNewObject("Chilkat_9_5_0.StringBuilder")

(SQL Server)
EXEC @hr = sp_OACreate 'Chilkat_9_5_0.StringBuilder', @obj OUT

(Javascript)
var obj = new ActiveXObject("Chilkat_9_5_0.StringBuilder");

Properties

IntValue
IntValue As Long
Introduced in version 9.5.0.58

Returns the content of the string converted to an integer.

top
LastMethodSuccess
LastMethodSuccess As Long

Indicate whether the last method call succeeded or failed. A value of 1 indicates success, a value of 0 indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

  • Any method that returns a string.
  • Any method returning a Chilkat object, binary bytes, or a date/time.
  • Any method returning a standard boolean status value where success = 1 and failure = 0.
  • Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to 1. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
Length
Length As Long (read-only)
Introduced in version 9.5.0.58

The number of characters of the string contained within this instance.

Methods

Append
Append(value As String) As Long
Introduced in version 9.5.0.58

Appends a copy of the specified string to this instance.

Returns 1 for success, 0 for failure.

top
AppendBd
AppendBd(binData As ChilkatBinData, charset As String, ByVal offset As Long, ByVal numBytes As Long) As Long
Introduced in version 9.5.0.64

Appends the contents of binData. The charset specifies the character encoding of the bytes contained in binData. The charset can be any of the supported encodings listed at Chilkat Supported Character Encodings. To append the entire contents of binData, set offset and numBytes equal to zero. To append a range of binData, set the offset and numBytes to specify the range.

Returns 1 for success, 0 for failure.

top

Introduced in version 9.5.0.58

Appends binary data using the encoding specified by encoding, such as "base64", "hex", etc.

Returns 1 for success, 0 for failure.

top

Returns 1 for success, 0 for failure.

top
AppendLine
AppendLine(value As String, ByVal crlf As Long) As Long
Introduced in version 9.5.0.65

Appends the value followed by a CRLF or LF to the end of the curent StringBuilder object. If crlf is 1, then a CRLF line ending is used. Otherwise a LF line ending is used.

Returns 1 for success, 0 for failure.

top
AppendSb
AppendSb(sb As ChilkatStringBuilder) As Long

top
Contains
Contains(str As String, ByVal caseSensitive As Long) As Long
Introduced in version 9.5.0.58

Returns 1 if the str is contained within this object. For case sensitive matching, set caseSensitive equal to 1. For case-insensitive, set caseSensitive equal to 0.

top
ContainsWord
ContainsWord(word As String, ByVal caseSensitive As Long) As Long
Introduced in version 9.5.0.69

Returns 1 if the word is contained within this object, but only if it is a whole word. This method is limited to finding whole words in strings that only contains characters in the Latin1 charset (i.e. iso-8859-1 or Windows-1252). A whole word can only contain alphanumeric chars where the alpha chars are restricted to those of the Latin1 alpha chars. (The underscore character is also considered part of a word.)

For case sensitive matching, set caseSensitive equal to 1. For case-insensitive, set caseSensitive equal to 0.

top
ContentsEqual
ContentsEqual(str As String, ByVal caseSensitive As Long) As Long
Introduced in version 9.5.0.62

Returns 1 if the contents of this object equals the str. Returns 0 if unequal. For case insensitive equality, set caseSensitive equal to 0.

top
ContentsEqualSb
ContentsEqualSb(sb As ChilkatStringBuilder, ByVal caseSensitive As Long) As Long
Introduced in version 9.5.0.62

Returns 1 if the contents of this object equals the sb. Returns 0 if unequal. For case insensitive equality, set caseSensitive equal to 0.

top
Decode
Decode(encoding As String, charset As String) As Long
Introduced in version 9.5.0.62

Decodes and replaces the contents with the decoded string. The encoding can be set to any of the following strings: "base64", "hex", "quoted-printable" (or "qp"), "url", "base32", "Q", "B", "url_rc1738", "url_rfc2396", "url_rfc3986", "url_oauth", "uu", "modBase64", or "html" (for HTML entity encoding). The full up-to-date list of supported binary encodings is available at the link entitled "Supported Binary Encodings" below.

Note: This method can only be called if the encoded content decodes to a string. The charset indicates the charset to be used in intepreting the decoded bytes. For example, the charset can be "utf-8", "utf-16", "iso-8859-1", "shift_JIS", etc.
