Convert pages to text and return a string.
convertToTextString([in] int firstPage, [in] int lastPage, [out, retval] BSTR *text)
This function converts the specified range of pages (firstPage through lastPage) to text, and returns the resulting text in a string.

If lastPage is -1, this function will convert up to the last page in the PDF file. (See also numPages.)

convertToTextString throws an error if text extraction is prohibited by this PDF file.

This function is identical to convertToTextFile except that it extracts to a string in memory rather than to a file on disk.

See the "Setting parameters" section in the function list for settings that affect text extraction.
