Bz2

When set to True, causes the currently running method to abort. Methods that always finish quickly (i.e.have no length file operations or network communications) are not affected. If no method is running, then this property is automatically reset to False when the next method is called. When the abort occurs, this property is reset to False. Both synchronous and asynchronous method calls can be aborted. (A synchronous method call could be aborted by setting this property from a separate thread.)

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.

The interval in milliseconds between each AbortCheck event callback, which enables an application to abort certain method calls before they complete. By default, HeartbeatMs is set to 0, meaning no AbortCheck event callbacks will trigger.

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: True means success, False 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.

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 "10.1.0"

BZ2 compress the contents of bd. After compression, the bd contains the binary content of a .bz2 file, which is slightly different than simple BZIP2 compressed data because a .bz2 file contains:

1. Header
2. Compressed blocks
3. End-of-stream trailer

Returns True for success, False for failure.

Creates an asynchronous task to call the CompressBd method with the arguments provided.

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns Nothing on failure

Compresses a file to create a BZip2 compressed file (.bz2).

Note: Both inFilename and toPath should be relative or absolute file paths (not just a path to a directory). For example someDir1/someDir2/myFile.txt or c:/someDir1/myFile.bz2.

Returns True for success, False for failure.

Creates an asynchronous task to call the CompressFile method with the arguments provided.

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Creates an asynchronous task to call the CompressMemory method with the arguments provided.

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns Nothing on failure

BZip2 compresses and creates a .bz2 file from in-memory data.

Returns True for success, False for failure.

Creates an asynchronous task to call the CompressMemToFile method with the arguments provided.

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns Nothing on failure

Loads the caller of the task's async method.

Returns True for success, False for failure.

BZ2 uncompress the contents of bd, which initially should contain the bytes of a .bz2 file. After uncompressing, the bd contains the original uncompressed content.

Returns True for success, False for failure.

Creates an asynchronous task to call the UncompressBd method with the arguments provided.

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns Nothing on failure

Unzips a .bz2 file.

Returns True for success, False for failure.

Returns Nothing on failure

Unzips a .bz2 file directly to memory.

Returns an empty byte array on failure

Creates an asynchronous task to call the UncompressFileToMem method with the arguments provided.

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns Nothing on failure

Unzips from an in-memory image of a .bz2 file directly into memory.

Returns Nothing on failure

Enables a method call to be aborted by triggering the AbortCheck event at intervals defined by the HeartbeatMs property. If HeartbeatMs is set to its default value of 0, no events will occur. For instance, set HeartbeatMs to 200 to trigger 5 AbortCheck events per second.

Args are passed using Chilkat.AbortCheckEventArgs

Event callback implementation:

Dim WithEvents bz As Chilkat.Bz2

Private Sub bz_OnAbortCheck(sender As Object, args As Chilkat.AbortCheckEventArgs) Handles bz.OnAbortCheck

    ...

End Sub

This provides the percentage completion for any method involving network communications or time-consuming processing, assuming the progress can be measured as a percentage. This event is triggered only when it's possible and logical to express the operation's progress as a percentage. The pctDone argument will range from 1 to 100. For methods that finish quickly, the number of PercentDone callbacks may vary, but the final callback will have pctDone equal to 100. For longer operations, callbacks will not exceed one per percentage point (e.g., 1, 2, 3, ..., 98, 99, 100).

The PercentDone callback also acts as an AbortCheck event. For fast methods where PercentDone fires, an AbortCheck event may not trigger since the PercentDone callback already provides an opportunity to abort. For longer operations, where time between PercentDone callbacks is extended, AbortCheck callbacks enable more responsive operation termination.

To abort the operation, set the abort output argument to True. This will cause the method to terminate and return a failure status or corresponding failure value.

Args are passed using Chilkat.PercentDoneEventArgs

Event callback implementation:

Dim WithEvents bz As Chilkat.Bz2

Private Sub bz_OnPercentDone(sender As Object, args As Chilkat.PercentDoneEventArgs) Handles bz.OnPercentDone

    ...

End Sub

This event callback provides tag name/value pairs that detail what occurs during a method call. To discover existing tag names, create code to handle the event, emit the pairs, and review them. Most tag names are self-explanatory.

Args are passed using Chilkat.ProgressInfoEventArgs

Event callback implementation:

Dim WithEvents bz As Chilkat.Bz2

Private Sub bz_OnProgressInfo(sender As Object, args As Chilkat.ProgressInfoEventArgs) Handles bz.OnProgressInfo

    ...

End Sub

Called from the background thread when an asynchronous task completes.

Args are passed using Chilkat.TaskCompletedEventArgs

Event callback implementation:

Dim WithEvents bz As Chilkat.Bz2

Private Sub bz_OnTaskCompleted(sender As Object, args As Chilkat.TaskCompletedEventArgs) Handles bz.OnTaskCompleted

    ...

End Sub
