How to write a txt file using AdobeIndesign CS4 Plugin

Here's how I do it:

void SaveToText()
{
   InterfacePtr<IPMStream> Output(StreamUtil::CreateFileStreamWrite(TagFileName));

   Output->Open();
   Output->XferByte((uchar *) Report.c_str(), Report.size());
   Output->Close();
}

The Report is some kind of string object.  Pile on your text into the string object and then use XferByte to save it all to the file you specify in TagFileName.  This works for both Mac and Win computers.

HTH!
