I have an ASHX file that receives some parameters (user and password). Using this parameters i need to send a zipfile as ASHX's result. I've written this code but when i open the downloaded zip, it appears to be corrupted.
Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
context.Response.Clear()
context.Response.ContentType = "application/x-zip-compressed"
Dim sLoginName As String = context.Request.QueryString("LOGIN_NAME")
Dim sLoginPassword As String = context.Request.QueryString("LOGIN_PASSWORD")
If (Not String.IsNullOrEmpty(sLoginName) And
Not String.IsNullOrEmpty(sLoginPassword)) Then
If (CheckLogin(sLoginName, sLoginPassword)) Then
Dim sZipUpdatePath As String = String.Empty
Dim sVersionToInstall As String = GetVersionToInstall(sLoginName, sLoginPassword)
Dim sZipName As String = "UPDATE.zip"
If (Not String.IsNullOrEmpty(sVersionToInstall) And
Not String.IsNullOrEmpty(sZipName)) Then
sZipUpdatePath = "~\Updates\" + sVersionToInstall + "\" + sZipName
context.Response.TransmitFile(context.Server.MapPath(sZipName))
End If
End If
End If
End Sub
How can solve it?

Good morning, I need to encrypt my querystring and i found an interesting method in this link and I convert it in vb.net:

Dim query As String = ExtractQuery(context.Request.RawUrl)
Dim path As String = GetVirtualPath()

but also my project use FriendlyUrls and I figured out that with FriendlyUrls the things does not working and always return the url without the extension ".aspx" but with the querystring not encrypted
Imports System.Web.Routing
Imports Microsoft.AspNet.FriendlyUrls
Public Module RouteConfig
Sub RegisterRoutes(ByVal routes As RouteCollection)
Dim settings As FriendlyUrlSettings = New FriendlyUrlSettings() With {
.AutoRedirectMode = RedirectMode.Permanent
}
routes.EnableFriendlyUrls(settings)
End Sub
End Module
of course if I set .AutoRedirectMode to Off it works but without friendlyurls.
Am I doing something wrong?
EDIT 09/10/2019:
We figured out that remove the test of OriginalString.Contains("aspx") in the context_BeginRequest the encryption works, now the code is like:
Private Sub context_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
Dim context As HttpContext = HttpContext.Current
If context.Request.RawUrl.Contains("?") Then
Dim query As String = ExtractQuery(context.Request.RawUrl)
Dim path As String = GetVirtualPath()
If query.StartsWith(PARAMETER_NAME, StringComparison.OrdinalIgnoreCase) Then
Dim rawQuery As String = query.Replace(PARAMETER_NAME, String.Empty)
Dim decryptedQuery As String = Decrypt(rawQuery)
context.RewritePath(path, String.Empty, decryptedQuery)
ElseIf context.Request.HttpMethod = "GET" Then
Dim encryptedQuery As String = Encrypt(query)
context.Response.Redirect(path & encryptedQuery)
End If
End If
End Sub
But now the question is: there is other method to target an aspx page without test the extension? I think there is a risk that targeting things that not should target like "ashx" or cache-busting code that use querystring.

I am processing PDF/JPG/GIF files using HTTP Handler.
A popup receives a btnId in query string and detects the file extension then calls the handler with btnId and processes the request.
Files are physical stored on server with file names in DB.
When there is an issue with the file like file not found or some error I want an alert to be displayed and opened window to be closed which is not working right now.
I know the reason and that is I am writing the alert into response which will eventually land in either object tag or Image tag.
Can some one please suggest how can this be achieved. Help will be appreciated. Thanks!!!

Can anyone give some advice?
I just need to know how I can get translated text to 3 different label language: label 1 for dutch language, label 2 for english language, and label 3 for indonesian language.
The final chunk of code in your example does the translation from English to Spanish. (The part that starts with Dim txtToTranslate...)
You will have to just use that 3 times (put it in a function) with once doing a translation from your target language to Dutch, once to English, once to Indonesian.
The part where the translation is specified is this:
Dim uri As String = "http://api.microsofttranslator.com/v2/Http.svc/Translate?text=" + System.Web.HttpUtility.UrlEncode(txtToTranslate) + "&from=en&to=es"
From=en means 'from English'
To=es means 'to Spanish'
So just amend that for the languages you need...

Now I want to add a session variable by generating a random string and add the uploaded images to the newly created random string.
1.I have seen this Question on SO to use System.Web.SessionState.IRequiresSessionState for sessions and how do I create a folder with that and add my images to that folder after doing that how do I access this session variable in my normal aspx page.
2.(Or) the better way is create session variable in aspx page and pass that to handler?If so how can I do that?
3 .I am trying to find the control from my handler.Is that possible?If anyone knows how to get this then also my problem will get resolved so that I am trying to create a session from m aspx page.
Can anyone explain the better way of handling this situation.
I completely agree with jbl's comment.
You can get and set session using HttpContext.Current.Session anywhere on your project.
No matter where you create the session. Just make sure that the session exists before you access it.
Not sure what exactly you are asking here(need some more explanation).
Here is an example, where I used session on HttpHandler. However, it is on c#(hope you can understand).
This is not really an answer but #Knvn wrote a C# example which I couldn't understand so I used a converter to convert it to VB. Posted it here in case it helps someone in the future.
