TChilkatBinData

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

• A timeout property set to 0, indicating an infinite timeout.
• A hang occurring within an event callback in the application code.
• An internal bug in the Chilkat code causing the hang.

This property is mainly used in SQL Server stored procedures to retrieve binary data from the last method call that returned binary data. It is only accessible if Chilkat.Global.KeepBinaryResult is set to 1. This feature allows for the retrieval of large varbinary results in an SQL Server environment, which has restrictions on returning large data via method calls, though temp tables can handle binary properties.

Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

Indicates the success or failure of the most recent method call: 1 means success, 0 means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.

In SQL Server stored procedures, this property holds the string return value of the most recent method call that returns a string. It is accessible only when Chilkat.Global.KeepStringResult is set to TRUE. SQL Server has limitations on string lengths returned from methods and properties, but temp tables can be used to access large strings.

The length, in characters, of the string contained in the LastStringResult property.

The number of bytes contained within the object.

If set to 1, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is 0. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

Version of the component/library, such as "10.1.0"

Appends the contents of another BinData to this object.

Returns 1 for success, 0 for failure.

Appends binary data to the current contents, if any.

Returns 1 for success, 0 for failure.

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 1 for success, 0 for failure.

Appends a single byte. The byteValue should be a value from 0 to 255.

Returns 1 for success, 0 for failure.

Appends a byte count followed by the string in the desired character encoding, such as "utf-8". The numCountBytes is the size in bytes of the integer to represent the byte count. If 0, then a minimal number of bytes is used. If bigEndian is 1, the byte count is appended in big endian byte ordering, otherwise little-ending byte ordering. The str is the string to be appended. The charset is the character encoding, such as "utf-8", "utf-16", "windows-1252", etc.

Returns 1 for success, 0 for failure.

Appends binary data to the current contents.

Returns 1 for success, 0 for failure.

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 1 for success, 0 for failure.

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 1 for success, 0 for failure.

Appends a 16-bit integer (2 bytes). If littleEndian is 1, then the integer bytes are appended in little-endian byte order, otherwise big-endian byte order is used.

Returns 1 for success, 0 for failure.

Appends a 32-bit integer (4 bytes). If littleEndian is 1, then the integer bytes are appended in little-endian byte order, otherwise big-endian byte order is used.

Returns 1 for success, 0 for failure.

Appends a string to this object, padded to the fieldLen with NULL or SPACE chars. If padWithSpace is 1, then SPACE chars are used and the string is not null-terminated. If fieldLen is 0, then null bytes are used. The charset controls the byte representation to use, such as "utf-8".

Note: This call will always append a total number of bytes equal to fieldLen. If the str is longer than fieldLen, the method returns 0 to indicate failure and nothing is appended.

Returns 1 for success, 0 for failure.

Appends the contents of a StringBuilder to this object.

Returns 1 for success, 0 for failure.

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 1 for success, 0 for failure.

Does either 16-bit or 32-bit byte swapping of the entire contents. If size equals 16, then swaps in 2 bytes (e.g., 0x1234 → 0x3412). If size equals 32, then swaps 4 bytes (e.g., 0x12345678 → 0x78563412)

Returns 1 for success, 0 for failure.

This method converts the character encoding of an object's contents from one format to another, such as from Windows-1252 to UTF-8. The allOrNone parameter determines error handling for unrepresentable bytes. If allOrNone is 1, the object's contents remain unchanged when errors occur. If 0, error bytes are discarded. The method returns 1 if successful and 0 if errors occur.

Returns 1 for success, 0 for failure.

Clears the contents.

Returns 1 for success, 0 for failure.

Return 1 if the contents of this object equals the contents of binData.

Return the index where the first occurrence of str is found. Return -1 if not found. The startIdx indicates the byte index where the search begins. The charset specifies the byte representation of str that is to be searched. For example, it can be "utf-8", "windows-1252", "ansi", "utf-16", etc.

Returns a zero-length byte array (as an OleVariant) on failure.
An empty array will have a VarArrayHighBound of -1 meaning 0 elements.
