I'm trying to filter submitted web sites by attempting to browse them while bouncing the request off of OpenDNS. If the page received is the OpenDNS page, I'll assume the page shoudld be blocked.
How might I accomplish this task using the System.Net.WebClient class?
I seem to remember reading the MSDN somewhere that there was another method to download files from URIs other than using the webclient object. I'm trying to download some raw php files but every time I use the webclient object the server interprets them as an HTTP request and instead serves the default web page that the php file builds and not the php code itself.
View 3 RepliesI'm downloading a file from my website using WebClient.DownloadFile(),I'm wanting to do it asynchronously, so my UI stays responsive, that would require me creating an array of web clients, is that bad practice? Or is it acceptable?I have looked into FileWebRequest, but thought WebClient looked easier to implement.
View 10 RepliesMy program takes user input, replaces all spaces with "+", then inserts it into a search url for a specified web host. For example, the user enters:"How long is a foot?"
The generated URL (in this case I'm using dogpile.com) is:
"http://www.dogpile.com/info.dogpl/search/web?&q=How+long+is+a+foot"
This method has worked before for me, but now I just get an Internal Server Error every time the code is executed.

I've got a code in VB that will download a txt file from a website. The problem is I want this file to be downloaded into whatever folder that my program is in. for example, if my program was in C:
andom_folder then I would want this txt file downloaded to C:
andom_folder
Here is some of my
My.Computer.Network.DownloadFile _
("http://www.mywebsite.com/test.txt", _
"define where file should go here")
But in the spot to put where to place the file, I can't just put C:andom_folder because individual users may have this program installed in other parts of there computer.

View 10 RepliesI am using AxWindowsMediaPlayer on VB.NET to preview MP3 files from the web so that the user can choose to download it if he likes it. It works. I just put a link in the URL property and after a while it begins playing. ... after a while, of course. Because it has to download the file first. Perhaps I realized that because of my slow connection XD. But that made me think: how can I tell if the player is currently downloading a file? So that I can put a label saying "Please wait, preparing file..." or something.

as per usual i am a little confused. I know DownloadStringAsync runs on a threaded pool with a default min and max threads limit, but what confuses is how would i call DownloadStringAsync say for example ten times.Example.I have an array with 10 URLS. Surely i would not use a for each loop of the array index to pass the url address while each time calling DownloadStringAsync(New Uri("someArray(index)") surely we can pass say a range of items from the array and let DownloadStringAsync decide on the threaded pool how many to process each time?
View 6 RepliesIn my web app, I have an aspx page which contains an html table and several lines of text. I need users to be able to download this whole page as a separate file.
In the past I have used the a webclient to do this:
Dim myWebClient As New System.Net.WebClient
myWebClient.DownloadFile(strSource, strDest)
Response.AddHeader("Content-Disposition", "attachment;filename=test.doc")
Response.Write("test.doc")
but it appears this is only able to download html pages.
I have some exe files that I've uploaded into my database as I don't want them to be publicly accessible. I tried using a link button and a generic handler to serve the file using the following code:
Context.Response.Clear()
Context.Response.ContentType = "application/exe"
Context.Response.AppendHeader("Content-Disposition", "filename=program.exe")
Context.Response.BinaryWrite(binaryfile)
The problem: Google Chrome does not treat the download as any other exe, instead after downloading it reports "program.exe is not commonly downloaded and could be dangerous." with a "discard" button and the option to "keep" the download is hidden under a context menu.
serve exe files stored in the database?
