IPersistFile::GetCurFile

Retrieves either the absolute path to the object's current working file or, if there is no current working file, the object's default filename prompt.

HRESULT GetCurFile(
  LPOLESTR *ppszFileName  //Pointer to the path for the current file 
                          //or the default save prompt
);

Parameter

ppszFileName: [out]Points to the location of a pointer to a zero-terminated string containing the path for the current file or the default filename prompt (such as *.txt). If an error occurs, ppszFileName is set to NULL.

Return Values

S_OK: A valid absolute path was successfully returned.
S_FALSE: The default save prompt was returned.
E_OUTOFMEMORY: The operation failed due to insufficient memory.
E_FAIL: The operation failed due to some reason other than insufficient memory.

Remarks

This method returns the current filename or the default save prompt for the object.

This method allocates memory for the string returned in the ppszFileName parameter using the IMalloc::Alloc method. The caller is responsible for calling the IMalloc::Free method to free the string. Both the caller and this method use the OLE task allocator provided by a call to CoGetMalloc.

The LPOLESTR type indicates a wide character string (two bytes per character); otherwise, the string has one byte per character.

The filename returned in ppszFileName is the name specified in a call to IPersistFile::Load when the document was loaded; or in IPersistFile::SaveCompleted if the document was saved to a different file.

If the object does not have a current working file, it should supply the default filename prompt that it would display in a "Save As" dialog. For example, the default save prompt for a word processor object could be:

*.txt

Notes to Callers

OLE does not call the IPersistFile::GetCurFile method. Applications would not call this method unless they are also calling the save methods of this interface.

In saving the object, you can call this method before calling IPersistFile:Save to determine whether the object has an associated file. If this method returns S_OK, you can then call IPersistFile::Save with a NULL filename and a TRUE value for the fRemember parameter to tell the object to save itself to its current file. If this method returns S_FALSE, you can use the save prompt returned in the ppszFileName parameter to ask the end user to provide a filename. Then, you can call IPersistFile::Save with the filename that the user entered to perform a "Save As" operation.
