jamietrent · 09-12-2009, 11:32 AM

i need it to work with this

progressBar1.Value += 10
DownloadFileFromURL("68.214.84.27/string.wz", "C:\\program files\\globalc\\cryptonyte");

theoobe · 09-12-2009, 11:37 AM

The code I posted earlier, plus...

Code:

DownloadFileFromURL("http://68.214.84.27/string.wz", "string.wz");

...seems to work for me. :-/

jamietrent · 09-12-2009, 11:38 AM

ummm let me try again

jamietrent · 09-12-2009, 11:43 AM

it comes up with an error that says access to the path has been denided

well the path is true but it still says that

theoobe · 09-12-2009, 11:49 AM

You can only write/modify files in the program files folder, if you have UAC (User Account Control) disabled. I dare say that is why you are denied access.

One area of your hard disk which will still have write/modify access is the Application Data folder. You can locate the path to this folder using

Code:

Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)

It is good practice to use this area to store your application's data files.

jamietrent · 09-12-2009, 12:04 PM

please tell me how to get it to work

C_ntua · 09-12-2009, 12:51 PM

theoobe is saying that you cannot save the file at

Code:

C:\\program files\\globalc\\cryptonyte

. So you need to choose a different location

The

Code:

Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)

returns a string with the Application Data folder, in which you can write.

So write in your Application Data folder and not in Program Files.

Don't know how you can change permissions and be able to write in Program Files
