I can't really tell if this is a bandwidth issue but I don't I will be able to debug this issue any further. Most likely it is the excessive bandwith usage indeed. I will continue by making a custom script and uploading the files to a web server of my own. Thanks for the help! I am trying to download a pdf, the download is working but the file is actually corrputed.
If you are downloading from Drive, make sure that the file is public. Probably it will consist of an HTML source code of an error page. I seem to be experiencing some issues.

FDEr Updated the code, now it supports asynchronous downloads as well as progress callback for these asynchronous downloads.
I just implemented this into my project. Although it comes up with an error regarding the sender, e part of the line when calling it. TotalBytesToReceive ; fileDownloader. WriteLine "Download completed" ;. I've copied the example code directly from Visual Studio after testing it. What does the error message say? Hi, Thanks for the code, very useful. I just encountered a problem - after downloading 4 small files on a queue using 4 FileDownloader, if I repeat the download queue a few times, I'm getting temp banned from google drive.
WebResponse GetWebResponse is returning a user-unhandled web exception from the server: "forbidden". Just me? Is there any walkaround about this? I haven't encountered this issue myself but I don't think we can implement a workaround for this. Does using a single FileDownloader to download those 4 files one after another change the outcome?
If it doesn't, the only possible solution for this issue is to listen to forbidden response and try again every X minutes. I saw there was a e2. ProgressPercentage was a variable, although it was only returning 0. It returned 0 for a couple seconds, went to , then back to 0 for the rest of the dowload. Also, e2. TotalBytesToReceive always returns WriteLine e2. ToString ; Sorry for the questions. Yes, unfortunately Drive doesn't provide Content-Length in the header of the download request, so WebClient isn't aware of the filesize until the download is completed.
Googling "drive download header Content-Length" yields this entry , you may try giving it a shot to determine the total file size. Can I reference the python script from my c file and return the int? Do you know how to do that? But thank you so much for this! ToString should work out-of-the-box. You are the first person that i have found that has a working solutions for everything! That's all the questions from me, thanks again. Quota shouldn't affect the owner of the file, thus you can continue accessing the file when logged in to Drive with your account.
Try opening the file in an incognito browser tab, I'm guessing that it won't work. This script doesn't copy the file to another Drive account while downloading it.
It attempts to download the file from the provided URL and if Drive presents the "File too large for virus scan" page, the script simulates clicking the "Download anyway" button, hence downloading the file no matter its size.
But when the Drive quota is reached, I'm afraid this script can't bypass that quota error. I can't see any possible reasons for this in the source code. I might be missing something but I just can't see it. That fixed it for me, thanks BigDaffa. Your code was exactly the thing I was looking for and it works perfectly! Well done!! NET experience. You can try using the online C to VB.
NET converters, though. Especially if it's about big sized files, we would love to see an auto-resume download functionality in this one!
What do you think? Yes, it would be a useful feature but I'm not planning to implement it myself at the moment. But thanks for the suggestion! If you are trying to learn how to create an interactable button with. Then, you should be able to implement this feature very quickly. How could i check if the download is done?
