Download Zip In Memory And Extract File To Disk

Jul 7, 2011

I am trying to programitally download a file from a https server, that uses cookies (and hence I'm using httpwebrequest). I'm debug printing the capacity of the streams to check, but the output [raw] files look different. Have tried other encoding to no avail.

Code:
Sub downloadzip(strURL As String, strDestDir As String)
Dim request As HttpWebRequest
Dim response As HttpWebResponse
request = Net.HttpWebRequest.Create(strURL)
request.UserAgent = strUserAgent
[Code].....

So I get the right size file downloaded, but dotnetzip does not recognise it, and the files that get copied out are incomplete/invalid zips.

2008 Express Edition: Attempted To Read Or Write Protected Memory, This Is Often An Indication That Other Memory Is Corrupt?

May 27, 2009

I cannot use Visual Basic 2008 at all. When I go to "new project" and choose "Windows Form Application" I get this error.I have tried multiple uninstall/reinstall with no result.A microsoft reply to this suggested that I needed: " .NET Framework 2.0 Service Pack 1 " I checked, and I did not have the .netframework 2.0 service Pack 1.
When I tried to download and install the above from Microsoft.com, the istaller said that "it was not allowsed" and I was not able to install the service pack 1.

I tried Uninstalling net framework 3.5, 3.0, 2.0 and then reinstalling .netframework 2.0 sevice pack 1; then reinstalling Visual basic 2008 express edition. At the reinstall of Visual basic 2008, .netframework 2.0 sevice pack 1 is unistalled by .net framework service pack 2.When I check the foruims for simiar problems, the formus are mostly for Visual basic 5.0, or other programs that I do not have.

Here is the programs I have installed:

Operating system: Windows XP
Microsoft .net framework 1.1
Microsoft .NET framwork 1.1 Hotfix(KB928366)
Microsoft .Net Framework 2.0 Service Pack 2

[code]....

All the security updates and hotfixes for Widows XP.

VS 2008 - Detect 404 For File Download

Jun 2, 2010

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.

VS 2008 Getting Application To Download A File

Oct 26, 2010

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]

VS 2008 OpenFileDialog Control That Will Read A Text File Into Memory - When Select All Files *.* It Does Not Re Appear?

Apr 24, 2012

I am writing an application that will use a OpenFileDialog control that will read a text file into memory and later process it.

I do have the following filter: Text files (*.txt)|*.txt|CSV files (*.csv)|*.csv|Spaced Text files (*.prn)|*.prn|All files (*.*)|*.*"

When I navigate to my test folder that contains a single .txt file, I see that file. When I change the filter to *.cvs that files goes disappears because it has a .txt extension. That is good. But when I select All files *.* it does not re appear? Why and how do I make it appear.

Download A File With A Download Timeout?

Feb 4, 2010

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?
