Rss

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.

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).

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.

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.

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.

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.

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).

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

The number of channels in the RSS document.

The number of items in the channel.

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.

Version of the component/library, such as "9.5.0.94"

Adds a new channel to the RSS document. Returns the Rss object representing the Channel which can then be edited.

Returns null on failure

Adds a new image to the RSS document. Returns the Rss object representing the image, which can then be edited.

Returns null on failure

Adds a new Item to an Rss channel. Returns the Rss object representing the item which can then be edited.

Returns null on failure

Downloads an RSS document from the Internet and populates the Rss object with the contents.

Returns true for success, false for failure.

Creates an asynchronous task to call the DownloadRss method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns null on failure

Returns the value of a sub-element attribute. For example, to get the value of the "isPermaLink" attribute of the "guid" sub-element, call item.GetAttr("guid","isPermaLink").

Returns null on failure

Returns the Nth channel of an RSS document. Usually there is only 1 channel per document, so the index argument should be set to 0.

Returns null on failure

Return the number of sub-elements with a specific tag.

The same as GetDate, except the date/time is returned in RFC822 string format.

Returns null on failure

Return the image associated with the channel.

Returns null on failure

Return the value of a numeric sub-element as an integer.

Return the Nth item of a channel as an RSS object.

Returns null on failure

Return the value of an sub-element as a string.

Returns null on failure

Load an RSS document from a file.

Returns true for success, false for failure.

Loads an RSS feed document from an in-memory string.

Returns true for success, false for failure.

Loads the caller of the task's async method.

Returns true for success, false for failure.

Get an attribute value for the Nth sub-element having a specific tag. As an example, an RSS item may have several "category" sub-elements. To get the value of the "domain" attribute for the 3rd category, call MGetAttr("category",2,"domain").

Returns null on failure

Get the value of the Nth occurrence of a sub-element. Indexing begins at 0.

Returns null on failure

Set an attribute on the Nth occurrence of a sub-element.

Returns true for success, false for failure.

Set the value of the Nth occurrence of a sub-element. Indexing begins at 0.

Returns true for success, false for failure.

Clears the RSS document.

Removes a sub-element from the RSS document.

Sets the value of a sub-element attribute.

Sets the value of a date/time sub-element to the current system date/time.

The same as SetDate, except the date/time is passed as an RFC822 string.

Sets the value of an integer sub-element.

Sets the value of a sub-element.

Returns the RSS document as an XML string.

Returns null on failure
