I am trying to create an instance of System.Web.HttpResponse to send the uers to another website.I am doing some other stuff in my vb.net that does not let me use the regular Response.Redirect.when I do Dim myRsp As System.Web.HttpResponse = New System.Web.HttpResponseit complains about a textwriter.
View 4 RepliesUser fills out this large page which is dynamically created based off DB values. Those values can change. When the user fills out the page and hits submit we want to save a copy of the page as html on the server, this way if the text or wording changes, when they go back to view their posted information, it is historically accurate.
So I basically need to do this
protected void buttonSave_Click(object sender, EventArgs e)
{
//collect information into an object to save it in the db
bool result = BusinessLogic.Save(myBusinessObject);
if (result)
//!!! Here is where I need to save this page as an html file on my servers IFS!!!!
else
//whatever
Response.Redirect("~/SomeOtherPage.aspx");
}
Also I CANNOT just request the data from the url because query string parameters are a big no no in this case. The key to pull the database info up (at its highest level) is all in session so I cant just request a url and save it.

View 1 RepliesI'm writing some code in which I need to use my own HttpResponse object to capture the output from a method on another object that takes an HttpResponse as a parameter. The problem is, this other object (which I cannot modify) calls HttpResponse.End(), which causes an "Object reference not set to an instance of an object" exception to be thrown. What can I do about this?
Dim myStringbuilder As New StringBuilder
Dim myStringWriter As New IO.StringWriter(myStringbuilder)
Dim myResponse As New Web.HttpResponse(myStringWriter)
someObject.doStuffWithHttpResponse(myResponse) ' calls myResponse.End() and crashes
Here's some more complete information about the error, thrown from the following code in a console application:
Dim myStringbuilder As New StringBuilder
Dim myStringWriter As New IO.StringWriter(myStringbuilder)
Dim myResponse As New Web.HttpResponse(myStringWriter)
Try
myResponse.End()
Catch ex As Exception
Console.WriteLine(ex.ToString)
End Try
Here's the text of the exception:
System.NullReferenceException: Object reference not set to an instance of an object.

I'm working on a functionality in my asp.net web site that enables the user to download some files as a zip file. I'm using the DotNetZip library to generate the zip file.
My code looks like this:
protected void OkbtnZipExport_OnClickEvent(object sender, EventArgs e)
{
var selectedDocumentIds = GetSelectedDocIds();
string archiveName = String.Format("archive-{0}.zip", DateTime.Now.ToString("yyyy-MMM-dd-HHmmss"));
AddResponseDataForZipFile(Response, archiveName);
try
{
string errorMessage = Utils.ExportToZip(selectedDocumentIds, arkivdelSearchControl.GetbraArkivConnection(), Response.OutputStream);
if (!string.IsNullOrEmpty(errorMessage)).......
Now, if anything goes wrong, say the Utils.ExportToZip method fails, I want to present an error message to the user and not the download dialog. Do I have to remove some data from the Response object in order to cancel the download operation?

I am trying to send an email from our web server to a gmail account via System.Net.Mail but am failing miserably receiving this error message:
Mailbox name not allowed. The server response was:
that domain isn't in my list of allowed rcpthosts (#5.7.1) Using this code I am able to send emails to other email addresses on our Outlook email server:
[Code]....
So I know I am capable of sending email to Gmail with port 587 and using the proper credentials of my own Gmail account. That is not the problem.
The problem is I want to be able to have the mail sent from my application from whatever the user puts in the FROM (Email address): text box to a Gmail account. When I use the above code, the address that the email is sent from is my own.
So the question is: Is there any way to configure this to be able to send from an Outlook email server to a Gmail account without having to use my Gmail account to actually do it (using my credientials). Therefore showing the email as sent from whatever the user puts in the txtEmail text box, and having it sent from the Outlook server?
I know my SMTP uses the port 25 for outgoing mail and I am pretty sure that the Gmail settings block port 25 for incoming mail, which makes sense, but what doesnt make sense is I can compose a message in Outlook and send it to a gmail account, but I cannot automate this through my programming, which makes me feel certain its my programming.
I have a message (System.Web.Mail.MailMessage) whose body is 400 bytes long, nothing in cc or bcc, has valid to/from addresses. But when I get to System.Web.Mail.WebMail.Send(msg) I get the exception [HttpException (0x80004005): Value does not fall within the expected range.] Not sure where to look. Google only provided a handful of options, mostly related to CDO.
View 2 RepliesIn my GridView I use FindControl/<FooterTemplate> with a TextBox that you can enter an integer with a comma
into the TextBox, because I create an instance of the Textbox first and then remove the comma out of the integer before the TextBox is used to update the table in the database.
However once the data is in the table and displayed in the GridView if you try to change the integer and use a comma in the GridView you cannot because FindControl/<EditItemTemplate> will not create an instance for you to remove the comma from the integer before it updates the table because FindControl/<EditItemTemplate> doesn't allow you to create an instance of the TextBox first, instead when you try to use the instance that looks like was created it gives an error stating:
Object reference not set to an instance of an object.
So the question is:
HOw do you create an instance of a TextBox in a GridView when using FindControl/<EditItemTemplate>?

View 1 RepliesWe recently migrated from VS 2008 to VS 2010. The migration went fine, except for our web project. Before, in VS 2008, the site showed up as http://localhost/Website. Now, it appears as C:...Website. It appears that when we did the migration, VS started to treat it as a file system website.
I've tried removing the existing site and re-adding it as an existing website, but it still displays it as C:...Website. Is there any way to convert it back to show it as a http://localhost/website, and run through IIS, as opposed to the default ASP.NET Development Server?

I have an issue with trying to create a Pdf file from my webpage. Basically, everythig involving creating the Pdf (using iTextSharp) is done, and I'm doing this as a File Stream (i.e, I'm saving the Pdf on local machine). Now what I'm trying to do is create it as a Memory Stream (i.e, open the Pdf from the browser). I was able to do this earlier when I wa still at the 1st version of the application, and all of the code behind was incluced in my .aspx.cs file. But now, I've kept the code in the .aspx.cs at a minimum and put the cude in classes and I'm creating onjects of thoses classes from the .aspx.cs
The problem is that the code from creating the Memory Stream is in a class as follows:

As you can imagine, the compiler cannot recognise "Response" as it's in a seperate class instead of in .aspx.cs
