MVC :: FileStreaming / Saving The Contents Of A Variable To Disk?
Nov 10, 2010
On my MVC2 web application I have a form that a user can enter dates, times, comments etc for appointments with clients. We then give him the oppertunity to download it as a vCalendar file. So far, on my controller I have the following code (I have just included the string that stored my vCard data) :
[Code]....
I have worked with uploading and downloading binary files within MVC, but working with stuff like this I am totally lost. This code needs to be saved as a .vcs from withing the client's browser. My return value looks something like this :

I am using ASP.NET 3.5 with iTextSharp and I have the following code:
var templatePath = Server.MapPath(@"~/Templates/template1.pdf");
var newFilePath = Server.MapPath(@"~/TempFiles/new.pdf");
PdfReader pdfReader = new PdfReader(templatePath);
PdfStamper pdfStamper = new PdfStamper(pdfReader, new FileStream(newFilePath, FileMode.Create));
AcroFields pdfFormFields = pdfStamper.AcroFields;
pdfFormFields.SetField("Box1", "007");
pdfFormFields.SetField("Box2", "123456");
pdfStamper.FormFlattening = false;
pdfStamper.Close();
Response.ClearContent();
Response.Buffer = true;
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition", "attachment;filename=new.pdf"));
Response.WriteFile(newFilePath);
Response.End();
The above code fills out a pdf file and saves the new file to the TempFiles folder. It then prompts the user to either save or open the file. Can I achieve the same functionality without saving the file to the TempFiles location?

I need to be able to read an excel file from a file upload control but I can not save the file to disk first, it must be done in memory.
[Code]....
Above is my code for reading the data file if it IS saved to disk, but again, I have to be able to do this without saving the file to disk, it must be done in memory. I have not been able to find any sample code anywhere on how to do this from memory, everything seems to force the file be uploaded, saved to disk, and then read in the connection string, which again I can not do.

i need to save multiple documents stored in SQL server as Image type to disk.
What i want to do is "backup" all files in a table (column) to disk, zip them and Response.TransmitFile(FilePath) to client.
I could use C# ot VB but that would require a lot of connections to database or a lot of server memory and i don't want that, becauze there are a lot of files to be saved Since SQL can write files to disk i was thinking about saving those files to disk directly from sql. Something like when u're doing a backup

My website provides a facility to upload images, using the ASP.NET FileUpload control. We accept both jpeg and tiff formats but I have just decided that all tiffs should be converted to jpegs at the time of upload. If possible, I want to avoid saving the original tiff to disk. I would any sample coding for achieving this conversion prior to saving (ideally in VB.NET, though I could always run C# code through a converter).

I was wondering, if I create a page e.g. index.aspx and I create it's contents based on a variable, would an AdSense block always show the same ad? Meaning is there a way to give it a dynamic content and having the ad addept to the content without creating a page for each content.For example I have a site with 3 links: pears, apples and lemons. I have a database which has the content of each page. I have a dynamic page index.aspx which modifies it's content based on the clicked link (the link always returns to index.aspx). If I want an ad to match my content, should I then do it differently? Like creating pages for each link and adding the content to each page dynamicly based on the link or something?

I have a publice variable to be used in the same webpage. when the user click on button 1, it does some process and assign a value to my public variable. After that, the user can click on button 2 which needs the public variable value to function. However I see the value of the public variable is 0 when I click on button 2.

I need to save data in a datatable on a web page where the user is adding items to order. I know how to create a datatable and add data to it. And I will be binding it to a gridview control. But I do not want to loose the data when the page does a postback. Do I need to save it to a session variable for this? Or will the data stay in the datatable?
I found this code posted online. Is this how I would save it to a session variable and then load it anytime?
Code:
Dim dt As New DataTable()
Session("MyDataTable") = dt
' To retrieve it from session
Dim dt As DataTable = DirectCast(Session("MyDataTable"), DataTable)

I am performing my first steps with ASP.NET for my employment.Yesterday I tried to perform saving a value to a sessionstate variable, but it does not work.I am using C# and want to code in .NET 3.5. [Code]....
The click performs a postback to a second website where the value is to be displayed on a simple label.The value I initialized in the Global.asax is saved to the variable and then read on the second page, but I cannot manipulate it using the textbox and the button on the first page. I just don't get it...I even tried on different machines and different VS editions.

I am testing with an MVC 2 project generated by the template in VS 2010. I have simply added an ADO.NET Entity Data Model, as well as a WCF Data Service that leverages the data model.
I was able to access the web application content (views, as well as the data served by the data service) just fine until the day before yesterday.
Yesterday I decided to reinstall Windows 7 on my development laptop, and I chose to go with the release of the OS with SP1. Of course, I reinstalled Visual Studio as well.
Now the same project gives me HTTP 404 errors when I try to browse to the data url .../MyTodoDataService.svc).
Here are some interesting facts:
The same data service works just fine in a Web Forms application. I see the problem only when deploying to the Local IIS Web Server (Cassini runs it just fine).
I am able to browse to the data url if force MVC routing to ignore the appropriate route by calling "IgnoreRoute" on the RouteCollection in Global.asax.

I have an application that I am working on. We are experiencing odd outages daily. The outages actually bring down the Virtual Servers (web farm of 4 VMs). The last odd metric before VM becomes inaccessible is that disk I/O is at 100%. While discussing this with the client, an idea was thrown out that I wouldn't have considered because I have never heard of such a thing. The idea was that our immense ViewState (yes I will be working on reducing that in the next release) overwhelmed the server or something and the server needed to start writing the ViewState to a file in a temporary folder somewhere. The thought was that when the server started to get overwhelmed, it would have to queue requests and would run out of memory and need to start using disk.
My application is poorly written and the viewstate is completely overused. However, it works 23+ hours of the day including through peak times without problems. But I have never heard of IIS or ASP.NET writing information to files on the server while queueing requests. I had no answer for this seemingly outrageous theory. Can anyone confirm for me that this is not how ASP.NET (2.0) or IIS are written?
