Don, does this export the report contents (data) to text or does it export the report definition to text?
Costa, if Don's suggestion just exports the report contents, I have some sample code on my website:

Look for "Code for CrystalDocumenter application". I don't remember which version of the SDK and VS I used for this - it's either VS 2005 and the 11.5 SDK or it's VS 2008 and the XI 3.1 SDK. It doesn't really make a difference as the two SDKs are almost the same. However, be aware that the version of the SDK that you're using has been out of support for several years and is not guaranteed to work in any version of VS newer than 2005.
