Sets or retrieves a configuration setting.

Syntax

officedoccontrol.Config ConfigurationString

Remarks

Config is a generic method available in every control. It is used to set and retrieve configuration settings for the control.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Open Method (OfficeDoc Control)

Opens the Open XML package archive.

Syntax

officedoccontrol.Open 

Remarks

When this method is called, the control will attempt to open the archive specified in PackagePath and extract package properties, content types and parse the master relationships file in the archive.

ParsePart Method (OfficeDoc Control)

Parses the specified part as XML.

Syntax

officedoccontrol.ParsePart 

Remarks

If the part specified by PartName exists, the corresponding physical file will be extracted from the archive and parsed as XML.

Syntax

officedoccontrol.Reset 

Remarks

Reset resets the state of the control. All properties will be set to their default values, and any files open will be closed.

Syntax

officedoccontrol.ResolveContentType 

Remarks

Applies the content type resolution rules specified in the Open XML packaging specification and returns the content type associated with PartName in the archive.

If there's no content type mapped for the part or for the extension, an empty string is returned.

BeginFile Event (OfficeDoc Control)

Fired before each file is processed.

Syntax

Sub officedoccontrol_BeginFile(Index As Integer, Skip As Boolean)

Remarks

BeginFile is fired before each file is processed by the compressor or decompressor, as appropriate. Index contains the array index of the file about to be processed, and the FileCompressedName, FileDecompressedName, FileCompressedSize (decompression only), and FileDecompressedSize fields of the Files collection for this index contain more detailed information about the file about to be processed.

When extracting, an alternate location may be specified by trapping the event, and modifying FileDecompressedName and/or ExtractToPath. If FileDecompressedName is set to an empty string, the file will not be written to disk. If WriteToProgressEvent is true, the file will still be decompressed, and the data may be extracted through the Progress event.

This event may also be trapped while compressing. FileCompressedName and FileDecompressedName may be changed.

You may set the Skip parameter to true in order to skip the file completely while compressing or extracting.

EndFile Event (OfficeDoc Control)

Fired after each file is processed.

Syntax

Sub officedoccontrol_EndFile(Index As Integer)

The Meta event is fired whenever a meta information section (<! ..text... >) is found in the document.

The full text of the meta section is provided by the Text parameter.

Overwrite Event (OfficeDoc Control)

Fired whenever a file exists and may be overwritten.

Syntax

Sub officedoccontrol_Overwrite(Filename As String, Overwrite As Boolean)

Remarks

Overwrite is fired when a file is about to be overwritten, and would overwrite an existing file. The event is fired during decompression.

Filename contains the full name of the file, specified with its pathname.

Overwrite specifies whether or not the file will be overwritten. For Zip, Jar, and Tar, this is equal by default to the value of the OverwriteFiles property. For Gzip, this value defaults to true.

Either of the parameters may be changed when the event is fired. Changing the value of Overwrite will override the default behavior of the control, and cause the file to be overwritten or not overwritten, depending on the value set. If Filename is changed, the value of Overwrite will be ignored, and the file will be written with the specified name. If a file of the new name also exists this file will be silently overwritten.

PI Event (OfficeDoc Control)

Filename contains the name of the file being written. If no file is being written, Filename will contain an empty string, and the output data will be provided exclusively through this event.

BytesProcessed contains the total number of uncompressed bytes processed. PercentProcessed contains the percent of uncompressed bytes processed, corresponding roughly to the running time of the operation.

For Gzip extraction only, BytesProcessed and PercentProcessed will reflect the number of compressed bytes extracted, as it is generally impossible to predetermine the total uncompressed size.

If WriteToProgressEvent is false, Data will contain null.

SpecialSection Event (OfficeDoc Control)

This event is fired when a special section is encountered.

Syntax

Sub officedoccontrol_SpecialSection(SectionId As String, Text As String)
