[@relaxyourmind6181]

Hello Sir, I was able to become really Good in both C# and Java thanks to your series! Sharing your knowledge is one of the best thing in the world. I have a question for you. * How to Generate a Report using C# ? Thanks you very much for the knowledge and best regards.

[@ragnarloth6531]

nice tutorial! p/s: for others, you may want to unsubscribe the event after you prompt out msgbox download completed. otherwise the msgbox will pop out twice after you click download button for the second time

[@johnnguyen1655]

Hi Ragnar, could you please share some code to unsubscribe the event?

[@glebi.r6]

Its very simpile private void FileDownloadComplete2(object sender, AsyncCompletedEventArgs e) { MessageBox.Show("Download Completed"); wc.DownloadFileCompleted -= new AsyncCompletedEventHandler(FileDownloadComplete); } If you want to unsubscrib an event just replace the "+" with "-" 👍

Thanks

[@zerogrim4786]

wow i like your video but sir how can i set the download location of the file that i wanna download? :o

[@kifkifa56]

Solved! Many have commented that file downloaded with zero bytes so I tried this on console application and solved this problem by just putting Console.Read(); after wc.DownloadFileAsync() method .... This is because without console.read(); the program exits before the file downloaded completely.

[@kwasim11]

Can you please send me your console app code... Thanks!

[@AnimeniacSimey]

Thanks so much! But how do you download file to a certain path? Thanks!

[@programmerfromhershey4205]

[@Luc_Skywalker]

this is fine when you know the file your going to download. If you were to download a file from WebBrowser to save on your computer, unknown file extension, now, how to catch that would be helpful!

[@johnnguyen1655]

[@jordangreenberg7990]

Can I create my own executable file, kind of like Google earth or a pc game, using your method? Please let me know about that. Also, can I get the downloaded .txt file from a survey as well with this method? Because the surveys never unlock for me that much. I have to get visual studio for this. Is that right? Please let me know. So thanks so much.

[@YasaaGaming]

This works good And File image file downloaded. But I try to open downloaded image Its not open.It show me error ( It appears that we don't support this file format. ) Help me to fix this problem..

[@mmas.3315]

I dont have asynccompleted Event arg. it doesnt show up? whats the problem

[@reindeboer7374]

Just put Console.Read(); after wc.DownloadFileAsync() to fix the unreadable file problems. It won't quit before completion!

[@mattlambert3118]

Are you sure this works for pdfs? This seems to work well for image files, but I can't get it to download anything else. Am I missing something? The videos are great, by the way.

[@mattlambert3118]

Matt Lambert I figured it out and wanted to share incase others run across the same problem. This is just my understanding, so anybody feel free to correct me if I'm wrong or there is a way to get around this.///////////////////// ////////////////////////////////////////////////////////////////////////////////////////////////////// *dashes aren't part of the code I'm just using them to clarify what's code and apperantly youtube isn't letting you use line breaks anymore, So I'm going to separate paragraphs with backslashes. /////////////////////////////////////////////////////////////////////////////////////////////////////////////////// Some links to pdf files are really links to pages that then redirect you to the pdf. The source code for the page linking you to a pdf file may follow the link url with an http statement that says, ------- rel="nofollow" ---------. That's apparently put there to tell google web spiders not to follow the link. If your program follows the link anyway, the page it goes to is going to ask it for some info that it needs to redirect you again to the actual pdf page. If your program doesn't give the page the info if asks for, you're stuck on that page trying to download something that isn't there. /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// Long story short, if the link to the pdf is followed up by ------- rel="nofollow" --------- in the source code, you're probably not going to your pdf's url and you're going to need to figure out a way to give the next page what it needs so you can then get the url it's going to redirect you do. I don't know how to do that, but if anyone else does or I'm completely wrong I encourage you to correct me. ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// Hope this helps somebody.

downloading a video is something else than a file, you would need to select the format (mp3/mp4 etc) and then the download
