Programmatically download a shared file using C++ Curl

Hi,

I developped an aplication in C++ that runs on Windows. I am trying to add a feauture in the program to download a shared file from my dropbox folder. I would like the downloading to go in background in similar way to windows API URLDownloadToFile(). The windows function downloads files from the web. But when I use the dropbox file link, the function downloads an html file instead of my file. I tried to use CURL library but got stuck with the access_token. I created an application access_token as described by Dropbox developper guide. When I use this access_token I receive authorization faliure error message. I wonder if the job I am trying to do is actually doable, and whether my approach is the right one. Where should I go or what should I do to get a shared file downloaded with my windows application. 

Thanks for your help

    I can confirm that your code works using either "raw=1" or "dl=1" endings. Seems you have network issues. That's it. ( Of course could be done some improvements in the code, like detect and automatically save in corresponding file, accordingly named file for example :wink: )

    Good luck!

    Makhlouf In case it helps with your the networking troubleshooting, note that the redirects to get to the file data when using 'raw=1' or 'dl=1' also go through other Dropbox domains that look like '*.dl.dropboxusercontent.com'.

    Dear Здравко, 1- Can you advise me where I can download a libcurl.dll file that should work for me. I need to make sure whether the issue source is the network or missing option in the library. 2- Also, I could not follow you regarding the improvement you suggested to my code. What do you mean by automatically save in corresponding file. Please explain more. Thanks a lot.
