See Also    ActiveX

Applies To

fpSpread control

Description

Saves the sheet in XML format and stores the information in a buffer.

Syntax

C

BOOL SSExportToXMLBuffer(HWND hWnd, LPCTSTR pszRoot, LPCTSTR pszCollection, HGLOBAL *hgBuff, long lFlags, LPCTSTR lpszLogFile);

C++

BOOL TSpread::ExportToXMLBuffer(LPCTSTR pszRoot, LPCTSTR pszCollection, HGLOBAL *hgBuff, long lFlags, LPCTSTR lpszLogFile);

Parameters

The following parameters are available:

Parameter Description
pszRoot Root element to use in the XML file
Do not use spaces in this string.
pszCollection Collection element to use in the XML file
Do not use spaces in this string.
hgBuff Returns the handle to the buffer
lFlags Whether to export formatted or unformatted data
Use one of the following values:
Constant Description
SS_EXPORTXML_FORMATTED To export data as formatted data
SS_EXPORTXML_UNFORMATTED To export data as unformatted data
lpszLogFile Path and file name of log file to create
If you do not provide a file name, the export will not create a log file. If you do not want to create a log file, set this parameter to NULL.

Remarks

This function is applied to the current sheet setting unless you first call the SSSetSheet function to specify the sheet for which you are calling this function.

Call this function to export a sheet to XML data in a buffer. The export creates XML data that provides the data as a set of tagged XML elements. The XML data created conforms to XML 1.0 guidelines.

Use the Root and Collection parameters to specify the root node necessary for valid XML data. The export uses the column headers in the sheet as the child elements within each collection element. If you provide custom text for the column headers, do not use spaces in the text; XML tags cannot contain spaces. If the sheet does not contain text in the column headers, the child element tags in the XML file default to <A>, <B>, <C>, and so forth. The export ignores any row headers.

Use the lFlags parameter to specify whether formatted or unformatted data is saved to the XML file. For more information about formatted and unformatted data, see Formatted and Unformatted Data.

Once you save a sheet by calling this function, you can call the SSLoadFromBuffer function to load the sheet into the fpSpread control. Pass the hgBuff from the SSExportToXMLBuffer function to the SSLoadFromBuffer function.

The following table summarizes the formats to which you can save data:

To Save To . . . Use Function
Binary file (proprietary format) SSSaveToFile
Tab-delimited file SSSaveTabFile or SSSaveTabFileU
Delimited file (offers user-defined delimiters) SSExportToTextFile or SSExportRangeToTextFile
or SSExportToTextFileU or SSExportRangeToTextFileU
Excel-formatted file SSExportExcelBook or SSExportToExcel
HTML file SSExportToHTML or SSExportRangeToHTML
XML file SSExportToXML or SSExportRangeToXML
XML buffer SSExportToXMLBuffer or SSExportRangeToXMLBuffer
An array SSGetArray

For instructions and more information about saving data to a buffer, see Saving to a Buffer. For more information about XML export, see XML File Export (online PDF manual). XML File Export lists and describes the method in which Spread property settings are interpreted in the XML data.

Return Type

True if the function completes successfully; False otherwise.
