BinData VB.NET WinRT Reference Documentation

BinData

Current Version: 9.5.0.73

Container for binary data. Provides methods for getting, setting, appending, etc. in binary and string encoded formats.

Object Creation

Dim obj As New Chilkat.BinData()

Properties

LastMethodSuccess
LastMethodSuccess As Boolean

Indicate whether the last method call succeeded or failed. A value of True indicates success, a value of False 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 = True and failure = False.
  • 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 True. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

NumBytes
NumBytes As Integer (ReadOnly)
Introduced in version 9.5.0.51

The number of bytes contained within the object.

Methods

AppendBd
Function AppendBd(ByVal binData As BinData) As Boolean
Introduced in version 9.5.0.62

Appends the contents of another BinData to this object.

Returns True for success, False for failure.

top
AppendBinary
Function AppendBinary(ByVal data As Byte()) As Boolean
Introduced in version 9.5.0.51

Appends binary data to the current contents, if any.

Returns True for success, False for failure.

top
AppendBom
Function AppendBom(ByVal charset As String) As Boolean
Introduced in version 9.5.0.62

Appends the appropriate BOM (byte order mark), also known as a "preamble", for the given charset. If the charset has no defined BOM, then nothing is appended. An application would typically call this to append the utf-8, utf-16, or utf-32 BOM.

Returns True for success, False for failure.

AppendEncoded
Function AppendEncoded(ByVal encData As String, ByVal encoding As String) As Boolean
Introduced in version 9.5.0.51

Appends encoded binary data to the current data. The encoding may be "Base64", "modBase64", "base64Url", "Base32", "Base58", "QP" (for quoted-printable), "URL" (for url-encoding), "Hex", or any of the encodings found at Chilkat Binary Encodings List.

Returns True for success, False for failure.

top
AppendEncodedSb
Function AppendEncodedSb(ByVal sb As StringBuilder, ByVal encoding As String) As Boolean
Introduced in version 9.5.0.62

Decodes the contents of sb and appends the decoded bytes to this object. The encoding may be "Base64", "modBase64", "base64Url", "Base32", "Base58", "QP" (for quoted-printable), "URL" (for url-encoding), "Hex", or any of the encodings found at Chilkat Binary Encodings List.

Returns True for success, False for failure.

top
AppendSb
Function AppendSb(ByVal sb As StringBuilder, ByVal charset As String) As Boolean
Introduced in version 9.5.0.62

Appends the contents of a StringBuilder to this object.

Returns True for success, False for failure.

top
AppendString
Function AppendString(ByVal str As String, ByVal charset As String) As Boolean
Introduced in version 9.5.0.62

Appends a string to this object. (This does not append the BOM. If a BOM is required, the AppendBom method can be called to append the appropriate BOM.)

Returns True for success, False for failure.

More Information and Examples
top
Clear
Function Clear() As Boolean
Introduced in version 9.5.0.51

Clears the contents.

Returns True for success, False for failure.

top
ContentsEqual
Function ContentsEqual(ByVal binData As BinData) As Boolean
Introduced in version 9.5.0.62

Return True if the contents of this object equals the contents of binData.

top
GetBinary
Function GetBinary() As Byte()
Introduced in version 9.5.0.51

Retrieves the binary data contained within the object.

Returns an empty byte array on failure

top
GetBinaryChunk
Function GetBinaryChunk(ByVal offset As Integer, ByVal numBytes As Integer) As Byte()
Introduced in version 9.5.0.51

Retrieves a chunk of the binary data contained within the object.

Returns an empty byte array on failure

top
GetEncoded
Function GetEncoded(ByVal encoding As String) As String
Introduced in version 9.5.0.51

Retrieves the binary data as an encoded string. The encoding may be "Base64", "modBase64", "base64Url", "Base32", "Base58", "QP" (for quoted-printable), "URL" (for url-encoding), "Hex", or any of the encodings found at Chilkat Binary Encodings List.

Returns Nothing on failure

top
GetEncodedChunk
Function GetEncodedChunk(ByVal offset As Integer, ByVal numBytes As Integer, ByVal encoding As String) As String
Introduced in version 9.5.0.51

Retrieves a chunk of the binary data and returns it in encoded form. The encoding may be "Base64", "modBase64", "base64Url", "Base32", "Base58", "QP" (for quoted-printable), "URL" (for url-encoding), "Hex", or any of the encodings found at Chilkat Binary Encodings List.

Returns Nothing on failure

GetEncodedSb
Function GetEncodedSb(ByVal encoding As String, ByVal sb As StringBuilder) As Boolean
Introduced in version 9.5.0.64

Writes the encoded data to a StringBuilder. The encoding may be "Base64", "modBase64", "base64Url", "Base32", "Base58", "QP" (for quoted-printable), "URL" (for url-encoding), "Hex", or any of the encodings found at Chilkat Binary Encodings List.

Returns True for success, False for failure.
