Properties

AuthorizationHeader
Function ComAuthorizationHeader Returns String
Introduced in version 9.5.0.53

The authorization header. This is what would be included in the Authorization HTTP request header if it is going to be used as the means for providing the OAuth1 authorization information.

top
BaseString
Function ComBaseString Returns String
Introduced in version 9.5.0.53

This is the exact string that was signed. For example, if the signature method is HMAC-SHA1, the BaseString is the exact string that passed to the HMAC-SHA1. An application does not set the BaseString property. The BaseString is exposed as a property to allow for debugging and to see the exact string that is signed.

top
ConsumerKey
Function ComConsumerKey Returns String
Procedure Set ComConsumerKey String value
Introduced in version 9.5.0.53

The consumer key.

top
ConsumerSecret
Function ComConsumerSecret Returns String
Procedure Set ComConsumerSecret String value
Introduced in version 9.5.0.53

The consumer secret.

top
DebugLogFilePath
Function ComDebugLogFilePath Returns String
Procedure Set ComDebugLogFilePath String value

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

  1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
  2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
  3. there is an internal problem (bug) in the Chilkat code that causes the hang.

top
EncodedSignature
Function ComEncodedSignature Returns String
Introduced in version 9.5.0.53

The URL encoded representation of the Signature property

top
GeneratedUrl
Function ComGeneratedUrl Returns String
Introduced in version 9.5.0.53

The URL that includes the OAuth1 query params.

top
HmacKey
Function ComHmacKey Returns String
Introduced in version 9.5.0.53

The exact HMAC key used to sign the BaseString. An application does not directly set the HmacKey. The HmacKey property is read-only and is provided for debugging to see the exact HMAC key used to sign the BaseString. The HMAC key is composed from the consumer secret (if it exists) and the token secret (if it exists).

top
LastBinaryResult
Function ComLastBinaryResult Returns Variant
Introduced in version 9.5.0.52

The binary data returned by the last (binary data returning) method called. Only available if Chilkat.Global.KeepBinaryResult is set to True. This provides a means for obtaining large varbinary results in the SQL Server environment (where limitations exist in getting large amounts of data returned by method calls, but where temp tables can be used for binary properties).

top
LastErrorHtml
Function ComLastErrorHtml Returns String

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorText
Function ComLastErrorText Returns String

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorXml
Function ComLastErrorXml Returns String

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastMethodSuccess
Function ComLastMethodSuccess Returns Boolean
Procedure Set ComLastMethodSuccess Boolean value
Introduced in version 9.5.0.52

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.

top
LastStringResult
Function ComLastStringResult Returns String
Introduced in version 9.5.0.52

The string return value of the last (string returning) method called. Only available if Chilkat.Global.KeepStringResult is set to True. This provides a means for obtaining large string results in the SQL Server environment (where limitations exist in getting long strings returned by method calls, but where temp tables can be used for string properties).

top
LastStringResultLen
Function ComLastStringResultLen Returns Integer
Introduced in version 9.5.0.53

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

top
Nonce
Function ComNonce Returns String
Procedure Set ComNonce String value
Introduced in version 9.5.0.53

The nonce.

top
OauthMethod
Function ComOauthMethod Returns String
Procedure Set ComOauthMethod String value
Introduced in version 9.5.0.53

The HTTP method, such as "GET", "POST", "PUT", "DELETE", or "HEAD". Defaults to "GET".

top
OauthUrl
Function ComOauthUrl Returns String
Procedure Set ComOauthUrl String value
Introduced in version 9.5.0.53

The OAuth URL, such as "http://echo.lab.madgex.com/echo.ashx". See http://bettiolo.github.io/oauth-reference-page/ to compare Chilkat results with another tool's results.

Note: The OAuthUrl should not include query parameters. For example, do not set the OAuthUrl equal to

https://rest.sandbox.netsuite.com/app/site/hosting/restlet.nl?script=165&deploy=1
Instead, set OAuthUrl equal to
https://rest.sandbox.netsuite.com/app/site/hosting/restlet.nl
and then subsequently call AddParam for each query parameter.

top
OauthVersion
Function ComOauthVersion Returns String
Procedure Set ComOauthVersion String value
Introduced in version 9.5.0.53

The oauth_version. Defaults to "1.0". May be set to the empty string to exclude.

top
QueryString
Function ComQueryString Returns String
Introduced in version 9.5.0.53

Contains the normalized set of request parameters that are signed. This is a read-only property made available for debugging purposes.

top
Realm
Function ComRealm Returns String
Procedure Set ComRealm String value
Introduced in version 9.5.0.70

The realm (optional).

top
Signature
Function ComSignature Returns String
Introduced in version 9.5.0.53

The generated base64 signature.

top
SignatureMethod
Function ComSignatureMethod Returns String
Procedure Set ComSignatureMethod String value
Introduced in version 9.5.0.53

TokenSecret
Function ComTokenSecret Returns String
Procedure Set ComTokenSecret String value
Introduced in version 9.5.0.53

The token secret

top
VerboseLogging
Function ComVerboseLogging Returns Boolean
Procedure Set ComVerboseLogging Boolean value

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

top
Version
Function ComVersion Returns String

Version of the component/library, such as "9.5.0.63"
