Reading a .txt file in VB.net. My file path is C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt.
This is my line of Dim LoanOptionsFile As String = "C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt"
I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?

i made downloader that will display the following items to the user. The Name of the file that the user is downloading The Url Were the file is being saved The Size of the file The speed at which the file is being downloaded And the Status. But the Problem is that the downloader can only download one file at a time. How can i make a multiple file downloader Which if the user wants to download 2 or 23 files he can.

I have a webapp where a datagridview is populated with records from a database and one of the columns is a download link to download the zip or exe file. We have the zip files on our server, but not the exe files as those are on another department's server. We have all of the file available for download, but if the user as an option selected in a dropdown, those url's in the gridview are re-formatted to be the exe file's on the other dept's server, however they don't have all of them (some 20% are missing) which means if the user click's the link they get their server's 404 not found page and can't download the file.
My PM (Project Manager) is asking me if I can have our webapp detect that the file doesn't exist on their server and instead of them getting the 404 page, they don't leave our app at all and get a javascript popup window or the page is refreshed with a red mark (and a message) next to the link they clicked on, is something like that possible? I have 2 restrictions with this, I can't modify the database because it doesn't contain file paths, it only contains a small portion like (Clinton County, Eaton County, Traverse County, etc..) and the rest of the url is formatted on the fly when the page is rendered, so there's no way to mark the missing files and there's no way we can host the files.

I got two issues getting my application to download a file. One small and one rather big.The downloader seems to have an issue using the users full download capability while the downloaded size is under 1 MB. As soon as it hits that, it seems to speed up with 10-100 times the previous speed.(Snippet at the end of the post)It seems to have to do with the filesize, which is about 5GB. As soon as my application hits about 1GB it completely locks up. (Without an error message, which I do have built in with a try...catch statement)I actually have to force quit the app to make it stop.It works perfectly fine with a 20MB file.I have the idea it's because of the int64's I use. But I need to use those (afaik) due to the big file size.[code]

I'm willing to compare a textfile (whatever) which contains a few lines of text. After the comparison it should download and replace the "changed" folder/file. E.g.
(Local txtFile)
maps: 1.0.0
db1: 1.0.0
db2. 1.0.0
(Server txtFile)
maps: 1.0.1
db1: 1.0.0
db2. 1.0.0

I want to download thousands of files from the web and save them locally. What is the most efficient way? It is important the failures timeout within 10 seconds.
Is there a better way to stream one stream into another? Maybe a smaller buffer, like 1024 bytes at a time, is more efficient for large files?
Dim w_req As System.Net.HttpWebRequest = CType(System.Net.HttpWebRequest.Create("http://blah.blah.blah/blah.html"), System.Net.HttpWebRequest)

I am writing a Windows Form program to automatically download and store generated PDF reports from a web site using the WebBrowser Control. The web site uses Ajax to link an icon back to the source aspx file which then returns a PDF file.
The problem I have is that the WebBrowser control brings up the File Save As dialog box when the PDF file is returned and I can find no way of handling this to cature and save the returned file. I have found other examples of how to manage this using the Navagating event to validate the extension of the file that is being accessed (e.g. [URL] and, if not an HTM, file then use the HTTP Web control to directly download the file. Unfortunately this will not work as the call references a .aspx page.
