This method is called by a file filter to open a destination file.

Syntax

STDMETHODIMP IPegasusFileFilterSite::OpenDestinationFile(
  int nHowToOpenFile,
  LPCSTR pszFullpath,
  LPVOID* ppObj
);

Parameters

• nHowToOpenFile
  [in] Specifies how the source file is to be opened. It is one of the following values.

  Value	Description
  PF_OPENFLAT	Open as a flat file.
  PF_OPENCOMPOUND	Open as an OLE compound file. Note that Windows Embedded CE does not support compound files.

• pszFullpath
  [in] Pointer to the null-terminated string that contains the name of the file to open to override the default destination file name. If this parameter is NULL, the default destination file name will be used.

• ppObj
  [out] Pointer to an LPVOID variable that receives an IStream pointer if nHowToOpenFile is PF_OPENFLAT, or an IStorage pointer if nHowToOpenFile is PF_OPENCOMPOUND. This object must be released using the IPegasusFileFilterSite::CloseDestinationFile method before returning to the mobile Internet browser.

Return Value

Returns NOERROR if the method completed successfully, otherwise returns HRESULT_FROM_WIN32.

Remarks

The default destination file name and path are specified in the PFF_DESTINATIONFILE structure that is passed in to the call to IPegasusFileFilter::NextConvertFile. The default path is temporary and is managed by the mobile Internet browser. For example, if the user drags a bitmap file named Tmp.bmp from the desktop computer to the Handheld PC, the default destination file name is Tmp.2bp.

The temporary destination file path must be located on the desktop computer, but the path can be modified as desired.

Note that OpenDestinationFile can be called only once within a specified call to IPegasusFileFilter::NextConvertFile.
