Send Fodder Bytes Until Actual Response Data Is Ready?
Jan 19, 2010
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?

If I were to specify a page for redirect using the ASP.NET Custom Errors feature, would my application still spit out the HTTP status code for that particular error?
For example if had a line in my web.config that had all Internal Server Errors redirect to Errors/500.aspx and then I encountered a 500 error, I would then be redirected to my custom Errors/500.aspx page. Will my application still respond with a HTTP 500 at any point in this exchange?

I have a bytes of data. Eg : 1024 bytes. And in that, say "Name Age Occupation" etc. All are only values. I have another skeleton xml which will have the <Name/><Age/> etc.
I need to loop through the bytes, say first 5 bytes is Name, Next 2 bytes is Age etc and fill up in this XML. I'll have 1000s of records and so need to know which way is the fastest.
Will the code be fastest or is there any way i can do by XSLT or similar component?

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 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 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;
}

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 ?

I'm new to ASP.net 3.5 and trying to create a test site so I can figure out how to use it in the real world. I have created a FormView (Formview1) based on a Client table using Linq Data Sources. The page includes a DropDownList to lookup Clients. I have added a list option (<asp:ListOption value="" Text="(Select Client)" and set AppendDataBoundItems=true so my added option is displayed. I decided to try to use Formview with only the Edit and Insert Modes, and I have set the Default Mode = Insert. When you open the page, a blank Client record is displayed.
The Client record contains serveral lookup fields and they have drop down lists for each. When I select a client from the Client DropDownList, is get the following message 'ddlClientType' has a SelectedValue which is invalid because it does not exist in the list of items I had this problem before and decided the best way to handle this (in the interim) was to turn off foreign key constraints for each of the lookup fields (e.g. ClientType) in SQL Server. That worked for 2-3 days. Now the problem has started again.
When I develop in other applications, I would simply create a lookup data source based on a Union Query with the actual data and a blank record. How can you do this using Linq DataSources. Can you get access and modify the queries?

I am trying to get a number returned from a webservice that executes a stored procedure and gets the record count from SQL. I then want to display an alert with the record count to the users, When they click on 'Check records' button. For now I am just using the alert to see if I could get a number back, here the code I am using:
$.ajax({
type: "POST",
url: "/WebserviceName.asmx/MethodName",[code]....
It just returns [object] rather than the actual data in the alert box in IE 7.0 however it works fine in Firefox and displays the valid record counts like 0, 10, 36 etc...So there some thing else I need to do to handle the JSON data in IE but

In my program, I need update a filed to the database. The field is for a pdf file content. I know, maybe I should save the pdf file to the local file system, and save the file path to the SQL. but, right now, it is the file content saved to the SQL.
from my program, it loads the file which is input by user. I use File.ReadAllBytes. Then, run the stored procedure on the SQL server, and use the bytes[] as parameter, to insert the file to the SQL. it works fine when file size is small. However, as file size becomes larger, say 200MB, sometimes, it pops out of memory exception.
So, I'm thinking, maybe I can load parts of the file, say 1MB a time, then update the database, then loop. so, this way, no matter how large the file is, it should not have any problem.
my question is: is there a standard way to do this? so, I should not save file content to the SQL at all? shoudl save file in file system, save the file path to sql only? or there are other way to deal with this?
