Help for Creating Objects in ASP

This control is part of the Chilkat Util ActiveX, which is included with any product that uses it.

The CkData object is simply an object that holds a chunk of data, which may be binary or text.

Properties

Base64LineLength As Long read/write

The line length to use when accessing data to the Base64 format.

Crlf As Boolean read/write

If TRUE, CRLFs are used when retrieving the data as a string, otherwise only CRs are used.

Description As String read/write

A description of what the data contains. When a CkData object is returned by a Chilkat component, such as with Chilkat Crypt for example, this will hold meaningful information. Chilkat Crypt returns descriptions such as "digital signature", "encrypted data", etc.

Filename As String read/write

If this data was loaded from a file, this is the name of the file from which it came.

NumBytes As Long read-only

The number of bytes held by this object.

Methods

Decrypt(cryptObject as ChilkatCrypt)

Uses a Chilkat Crypt object to decrypt the data. An error is raised if the data is not successfully decrypted.

Encrypt(cryptObject as ChilkatCrypt)

Uses a Chilkat Crypt object to encrypt the data. An error is raised if the data is not successfully encrypted.

GetBase64() As String

Return the data in Base64 format

GetBinary() As Variant

Return the binary data as an array of bytes.

GetChunk(fromIndex As Long, numBytes As Long) As Variant

Return a chunk of binary data, beginning at fromIndex. The first byte is at index 0.

GetQuotedPrintable() As String

Return the data in quoted-printable format.

GetString() As String

Return the data as a string. WARNING: This does an implicit conversion to Unicode from the ANSI code page. CkData assumes it is holding single-byte character data, and is internally calling the Windows MultibyteToWideChar Win32 function to convert the data. If your CkData contains character data in other encodings, such as utf-8, shift-jis, gb2312, euc-jp, iso-2022-jp, ..., then you shouldn't call this method. Use GetBinary to retrieve the character data unmodified.

LoadBase64(base64Data As String)

Decodes from Base64 format and loads the data.

LoadBinary(binaryData As Variant)

Loads binary data.

LoadFile(filename As String) As Boolean

Loads data from a file. Returns TRUE for success, FALSE for failure.

LoadQuotedPrintable(qpData As String)

Decodes from Quoted-Printable format and loads the data.

LoadString(data As String)

Loads a string.

RealTimeCompress(compressObject as ChilkatRtCompress)

Compresses the data using real-time compression offered by a ChilkatRtCompress object. An error is raised if not successful.

RealTimeDecompress(compressObject as ChilkatRtCompress)

Decompresses the data using real-time compression offered by a ChilkatRtCompress object. An error is raised if not successful.

SaveToFile(filename As String) As Boolean

Saves the data to a file. Returns TRUE for success, FALSE for failure.
