MVC :: Manipulate Response Before Send To The Client?
Jul 23, 2010
I create my own litte ViewEngine, done many things that works great, but now I want something to implement, but I don't know how.
I want the final Response Content when the controller is executed and the view is executed, manuelly manipulate and than send to the client.
I have two Examples for it.
First I have an AssetManager, he collects all Css files and JavaScript files, given by components, the view, classes and so on.
And this collected links I will insert with String.indexOf before the "</head" tag.
The reason why I want do this in the engine and not with a line like this in the head part
[Code]....
Is that I want so save me the work to do this every time on each project in the master page and maybe in single views.
A second usefull idea is, I want to write my own litte trace component, and I want so write the generated content before the "</html>" tag.
where I can manipulate the content before sending it to the client, and this in the engine?

I have an ASP.NET web application for data entry, and we have big lists of radiobuttons, and long lists of checkboxes, in some sections.
The client wants to be able to be able to navigate and manipulate these controls with their keyboard, like the tab/space/enter/right-left-up-down-arrow-keys. Are there any ASP.NET controls that I can use?

I am getting my Request from a third party application(different domain) to my ASP application. I am handling the request and doing the business part in my application and as a acknowledgement I need to send XML string as Response to the same Page which POSTED the request to my Application. I was successful in retrieving the input from Request using the following code
NameValueCollection postPageCollection = Request.Form;
foreach (string name in postPageCollection.AllKeys)
{
... = postPageCollection[name]);
}
But i am not sure how to send back the response along with XML String to the site(different domain)?
EDIT: How to get the URL from where the POST happened.

I have a webservice that sends the response back in XML format.I'm able to connect and call the webservice adding an external web reference to the Visual Studio project.Then in my code behind:As New servicename_addedLabel1.Text = servicename_added.Functionexposed(param1, param2, etc)With that code I can get the response in a large label and unstructured data. If I "view source" I see the XML structured data.I have tried to create an XML document without success.My goal is to parse the response and write it to a database separating all the fields.

I'm using Filestream for read big file (> 500 MB) and I get the OutOfMemoryException. Any solutions about it??
I want this in my app:
Read DATA from Oracle
Uncompress file using FileStream and BZip2
Read file uncompressed and send it to asp.net page for download. When I read file from disk, Fails !!! and get OutOfMemory.
. My Code is:
using (var fs3 = new FileStream(filePath2, FileMode.Open, FileAccess.Read))
{
byte[] b2 = ReadFully(fs3, 1024);
}
// http://www.yoda.arachsys.com/csharp/readbinary.html
public static byte[] ReadFully(Stream stream, int initialLength)
{
// If we've been passed an unhelpful initial length, just
// use 32K.
if (initialLength < 1)
{
initialLength = 32768;
}
byte[] buffer = new byte[initialLength];
int read = 0;
int chunk;
while ((chunk = stream.Read(buffer, read, buffer.Length - read)) > 0)
{
read += chunk;
// If we've reached the end of our buffer, check to see if there's
// any more information
if (read == buffer.Length)
{
int nextByte = stream.ReadByte();
// End of stream? If so, we're done
if (nextByte == -1)
{
return buffer;
}
// Nope. Resize the buffer, put in the byte we've just
// read, and continue
byte[] newBuffer = new byte[buffer.Length * 2];
Array.Copy(buffer, newBuffer, buffer.Length);
newBuffer[read] = (byte)nextByte;
buffer = newBuffer;
read++;
}
}
// Buffer is now too big. Shrink it.
byte[] ret = new byte[read];
Array.Copy(buffer, ret, read);
return ret;
}

I've been pulling my hair out about this for ages. I have a WebService which sends a zip file to the browser. This works; when I test the WebService and 'invoke' the method through it directly, the zip file is downloaded to the browser correctly.
The problem arises when I use jQuery to send an AJAX request to the WebService - the zip file is downloaded to the response, but it stays in the response and doesn't download as a file.
Here is my code:
[Code]....
Now this works since the file downloads when I use the 'invoke' function when navigating directly to the service.
Here is my jQuery AJAX request...
[Code]....
I added the code in 'beforeSend' so that the request states explicitly what type of response the browser should expect.
I've been using Firebug to monitor the request/response headers and can't see anything wrong with them (except when I look at the content of the response, it's full of binary data AND its the same size as the file I'm sending.
I just attempted to upload screen-dumps of the request/response headers and the content of the reponse but I don't have enough reputation points to do this yet :-(
The Response is the same size of the Zip file so I'm assuming its being sent back to the browser, but the browser doesn't know what to do with it.
Tested in IE, FF & Chrome and the results are consistent.

I got a strange issue after hosting the my site in IIS 7.5, Windows server 2008 64 bit
The applicaion is created in ASP.Net 2.0
The page with issue has following workflow:
Upload a file from browser (may be very large size ~50 MB)Perform some process (May take very long time: up to 30 minuits)Notifies the client that process is done.During the process client uses something like http://www.codeproject.com/KB/session/Session_Defibrillator.aspx to keep the session alive.
The Issue:
The client does not get any response sent by my code after the process is over. It should refresh the page with the response provided by my code. But instead it only shows waiting for... in the status bar.
I have tried this on IE and firefox.
To veryfy the process is over
I have added some trance message in my code to check when the process gets finished.I have also checked the Log from IIS, it also shows that response sent with Code 200.
Please help me solving this issue:
What could be the issue?How can I diagnose and fix this problem?In what cases connection between browser and IIS server gets lost.

I need to serve MP3 content that is generated dynamically during the request. My clients (podcatchers I can't configure) are timing out before I'm able to generate the first byte of the response data.
Is there a way to send fodder/throwAway data while I'm generating the real data, to prevent/avoid the timeout, but in a way that allows me to instruct the client to ignore/discard the fodder data once I'm ready to start sending the "real" data?

I have a page that when the user clicks a button there is a custom loading panel placed in the update panel by the PageRequestManager BeginRequest event. So when the page is loaded the loading panel is removed. My issue is that when the user clicks a button that redirects to an httphandler the page is not reloaded therefore the loading panel is never removed.
So I'm trying to think of a way to remove the loading panel before the redirect occurs, whether this be with a client script call before the redirect or what ever. So far I've thought about trying to do Response.write("..."), then Response.Redirect().

There are bunch of files stored in a DataBase as varbinary/image data. I am writing a program to extract these file data and send them to the browser so file can be opened or saved. My method is,
[code]....
BUT this method creates a file in the Server and then transmit to the browser. Means 100s of files will be created in the server when I open 100s of files with this process, naturally I want to avoid that.
Is it possible to do this without creating a copy of the file in the server ?

This question seems to be pretty close to what I am looking for - I was able to setup tracing and I am looking at the log entries for my calls to the service.However I need to see the raw soap request with the data I am sending to the service and I see no way of doing that from the SvcTraceViewer (only log entries are shown but no data sent to the service) - am I just missing configuration?

<source name="System.ServiceModel"

There is an external (Java based ) web service that i am calling. I've added my service reference and verified that Reference.cs has been generated.
Then i call my service form my client website like such:
[Code]....
But my response object is mostly null after it receives the response. The properties that should have values do NOT.
When i look at Trace viewer, the SOAP request is correct and the SOAP response is correct. I get back a valid soap response with all the data i need it's just not making its way back to my response object. I've tried regenerating the proxy many different ways (svcutil) with no luck.
Example of what is in the response object (good data which is not making it's way back to my response object):
<ogc:Spatial_Capabilities><ogc:GeometryOperands><ogc:GeometryOperand>gml:Envelope</ogc:GeometryOperand><ogc:GeometryOperand>gml:Point</ogc:GeometryOperand><ogc:GeometryOperand>gml:LineString</ogc:GeometryOperand><ogc:GeometryOperand>gml:Polygon</ogc:GeometryOperand></ogc:GeometryOperands><ogc:SpatialOperators><ogc:SpatialOperator name="BBOX"></ogc:SpatialOperator><ogc:SpatialOperator name="Overlaps"></ogc:SpatialOperator></ogc:SpatialOperators></ogc:Spatial_Capabilities>
Why isn't the SOAP response making its way back to my response object?

Basically I have to generate a rather large XPS document serverside and send this back to the client.
The issue I have whilst trying to do this is because the XPS document needs to be created on a STA thread, so either the response is sent back before the async operation is complete (in which case I can't attach the file using the transferfile method) OR I have to wait until the Async thread has completed and then I can send the file using the transferfile method (but this leaves the current page locked out for quite a while).

I am using the code below to enable clients to download a .csv file from my server.
The problem I am having is that when the file is saved to the client computer the file name is prefixed and suffixed with an underscore which leads to a file type of .csv_ which is obviously not a recognised file type.
How can I strip the underscores from the file name at the transmit stage?
Dim FileName As String = LstBox1.SelectedItem.ToString
Dim FilePath As String = "~/temp" & FileName
Response.Clear()
Response.ContentType = "text/csv"
Response.AddHeader("Content-Disposition", "attachment; filename=" & FileName & "")
Response.TransmitFile(FilePath)
Response.End()

I have a web form which does a full page postback when a button is clicked. This is caused by an update panel trigger. Client-Side: When the button is clicked, an animation gif is displayed Server-Side: When the button is clicked, the server side event changes the content type to excel, binary writes out excel content (byte array) and does Response.Flush() and Response.End() Client-Side: User is asked to either open or download the excel file. Animation gif is still displayed.
Question: How can I detect client side (using jQuery or Ajax) that the response has been completed. There is no page postback because the code-behind has cut off the response by using Response.End().

We have n-tier asp.net app with approx 200 pages and 400 classes spanned over many dlls . When we want to send patch (single .aspx page changed) we have to compile it as a solution and deployed for QA testing. Once QA tested, we need to send the patch to client where we face problem. Now, we need send the entire published folder which includes many code that are not part of changes.
