Jar ConfigurationThe component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.
Jar Configuration Settings
If true, the component requests an exclusive lock during initialization.If set to true, the component will request an exclusive lock during initialization to ensure there are no other processes locking a file. This is a temporary lock and is released before work is done. This is especially useful when another process has a partial lock on a file, for instance when Outlook is working with a .pst.
False by default.
|CloseStreamAfterCompress: If true, the component will close the output stream after compression.This property is true by default. Therefore, by default, the output stream will be closed after compression is completed. In order to keep streams open after the compression completes, you must set this config to false.|
Encoding to be used for filenames.The encoding to be used for filenames, and for Zip files, the password. The file contents are
treated as binary data, and so encoding does not apply to the contents.
At present only supported for Zip and Jar.
Default - Zip: "" (use default encoding of current machine, if possible)
Default - Jar: "UTF-8"
Example - This would set encoding to Japanese Shift-JIS.
Attributes of files to be excluded.
Files with attributes matching those specified will be excluded from compression or decompression. May be set to any
combination of H (hidden), S (system), A (archive), and R (read-only).
(Example: "HSR") Alternatively, may be set to a bitmask of the following flags:
Readonly (1), Hidden (2), System (4), Directory (16), Archive (32).
For Java, when compressing, attributes other than "H" and "R" will be ignored (due to JRE limitations).
Default: "" (no excluded attributes)
|ExtractFilesOnly: Whether to only extract the files contained within the archive. If true, only the files contained within the ArchiveFile are extracted directly to the specified ExtractToPath. Folders contained within the ArchiveFile will not be created within the ExtractToPath. If an archive contains files with the same name, you can control whether or not they get overwritten by setting OverwriteFiles.|
|OverwriteReadonlyFiles: Whether to overwrite readonly files. If true, the component will overwrite readonly files when decompressing. If false (the default), the component will fire the Error event, instead, and will fail with an exception if the error is not trapped and explicitly ignored in the event.|
Whether or not to write data to the Progress Event.If WriteToProgressEvent is set to true, then all data produced through invocations
of Extract, ExtractAll, and Compress will be written to the Progress
event as well as to disk. Applications may stream out the compressed or decompressed
data by trapping this event and copying the data.
By default, this config is set to false.
Base Configuration Settings
|BuildInfo: Information about the product's build.When queried, this setting will return a string containing information about the product's build.|
Tells the component whether or not a message loop is available for processing events.In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The component will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.
In some non-GUI applications an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the component does not attempt to process external events.
Information about the current license.When queried, this setting will return a string containing information about the license this instance of a component is using. It will return the following information:
Tells the component whether or not to use the system security libraries or an internal implementation.
By default the component will use the system security libraries to perform cryptographic functions.
When set to False calls to unmanaged code will be made. In certain environments this is not desirable.
To use a completely managed security implementation set this setting to True.
Setting this to True tells the component to use the internal implementation
instead of using the system's security API.
Note: This setting is static. The value set is applicable to all components used in the application.
When this value is set the product's system DLL is no longer required as a reference, as all unmanaged code is stored in that file.
