Config Method (OfficeDoc Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

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

These 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.

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.

ExtractPart Method (OfficeDoc Component)

Remarks

Looks up a package property named PropName in namespace PropNamespace in the core and app properties tables and returns it's value, if found.

If the property doesn't exists, an empty string is returned.

For custom properties. use an empty string ("") as the value of the PropNamespace parameter.

ListParts Method (OfficeDoc Component)

Syntax

void __fastcall Open();

Remarks

When this method is called, the component 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 Component)

Parses the specified part as XML.

Syntax

void __fastcall ParsePart();

Remarks

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

If BuildDOM is disabled, only the XML parser-related events will be fired.

ReadRelationships Method (OfficeDoc Component)

Reads the relationships file in the archive associated with the specified part.

If the part doesn't exists, it's stored in interleaved format, or PartData is null or empty, an error will be raised.

Reset Method (OfficeDoc Component)

Resets the component.

Syntax

void __fastcall Reset();

Remarks

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

ResolveContentType Method (OfficeDoc Component)

Returns the content type of the specified part.

Syntax

String __fastcall 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.

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 component, 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 Component)

Fired when a processing instruction section is encountered.

Syntax

typedef struct {
  String Text;
} TipzOfficeDocPIEventParams;
typedef void __fastcall (__closure *TipzOfficeDocPIEvent)(System::TObject* Sender, TipzOfficeDocPIEventParams *e);
__property TipzOfficeDocPIEvent OnPI = { read=FOnPI, write=FOnPI };

Remarks

The PI event is fired whenever a processing instruction section (<? ..text... ?>) is found in the document.

The full text of the processing instruction is provided by the Text parameter.

Progress Event (OfficeDoc Component)

Fired as progress is made.

Syntax

typedef struct {
  String Data;
  DynamicArray<Byte> DataB;
  String Filename;
  __int64 BytesProcessed;
  int PercentProcessed;
} TipzOfficeDocProgressEventParams;
typedef void __fastcall (__closure *TipzOfficeDocProgressEvent)(System::TObject* Sender, TipzOfficeDocProgressEventParams *e);
__property TipzOfficeDocProgressEvent OnProgress = { read=FOnProgress, write=FOnProgress };

Remarks

The Progress event is automatically fired as compression or decompression is performed. When WriteToProgressEvent is true, the output data is provided through the Data parameter, allowing for it to be streamed out.

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 Component)

Fired when a special section is encountered.

Syntax

typedef struct {
  String SectionId;
  String Text;
} TipzOfficeDocSpecialSectionEventParams;
typedef void __fastcall (__closure *TipzOfficeDocSpecialSectionEvent)(System::TObject* Sender, TipzOfficeDocSpecialSectionEventParams *e);
__property TipzOfficeDocSpecialSectionEvent OnSpecialSection = { read=FOnSpecialSection, write=FOnSpecialSection };

Remarks

The SpecialSection event is fired whenever a special section (such as <![ CDATA [ ..text... ]]>) is found in the document.

The full text of the special section is provided by the Text parameter, while the SectionId parameter provides the section identifier (e.g. "CDATA").

StartElement Event (OfficeDoc Component)

Fired when a begin-element tag is encountered in the document.

Syntax

typedef struct {
  String Namespace;
  String Element;
  String QName;
  bool IsEmpty;
} TipzOfficeDocStartElementEventParams;
typedef void __fastcall (__closure *TipzOfficeDocStartElementEvent)(System::TObject* Sender, TipzOfficeDocStartElementEventParams *e);
__property TipzOfficeDocStartElementEvent OnStartElement = { read=FOnStartElement, write=FOnStartElement };

Remarks

The StartElement event is fired when a begin-element tag is found in the document.

The element name is provided through the Element parameter. The attribute names and values (if any) are provided through the AttrName, AttrNamespace, AttrPrefix, and AttrValue properties.

The IsEmpty parameter is true when the event corresponds with an empty element declaration.

StartPrefixMapping Event (OfficeDoc Component)

Fired when entering the scope of a namespace declaration.

Syntax

typedef struct {
  String Prefix;
  String URI;
} TipzOfficeDocStartPrefixMappingEventParams;
typedef void __fastcall (__closure *TipzOfficeDocStartPrefixMappingEvent)(System::TObject* Sender, TipzOfficeDocStartPrefixMappingEventParams *e);
__property TipzOfficeDocStartPrefixMappingEvent OnStartPrefixMapping = { read=FOnStartPrefixMapping, write=FOnStartPrefixMapping };

Remarks

The EndPrefixMapping event is fired when leaving the scope of a namespace declaration.

Config Settings (OfficeDoc Component)

The 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.

OfficeDoc Config Settings

Base Config Settings

Trappable Errors (OfficeDoc Component)

Errors

The following errors may be generated by the component. Note that frequently the error message will contain more specific information than what is listed here.

Note that some non-fatal errors may be trapped and explicitly ignored in the Error event. This will allow the component to continue operation even in case of error.

OfficeDoc Errors

	268   The specified part name could not be found on the package, or the part is stored in interleaved format.
