It really should be pretty straightforward - especially if you can just pass the file name to upload/download from vfp to .NET.

Just create a 'class library' project and expose public methods to upload and download (passing in the filename).
You can easily test it in a .NET environment by running it from a console app. Once your happy with that than register it for COM interop (on the properties 'Build' page) and you should then be able to load it as any other COM object from VFP.....

>>>I have been asked to use a restful API (I believe that's what it's called to retrieve and post files to a folder on the web - or in the cloud as is the common term now).

>>>I have been given the following information:

>>>Viewing:

>>>To view a document simply go to the following URL. It will output a pdf file.

>>>http://***.***.***.***/api/index.php/documents/index/

>>>Uploading:
>>>
>>>To upload a file you have to do a HTTP POST to this URL:
>>>
>>>http://***.***.***.***/api/index.php/claims/upload
>>>
>>>It expects 2 parameters:
>>>
>>>doc_pk - the primary key for the field in the ClaimDocuments table which holds the description etc on the document

>>>This is a sample of the code I use to upload a document:

>>>
>>>As you can see I first read the contents of the file, then encode it, then send it to the RESTful server.

>>>
>>>The error variable will be true or false. The message will correspond to the error state.

>>>To force an error you can POST to the URL with no variables.
