Just wondering if anyone has any idea how you can determine how many bytes of a request have been read/received by the server... In other words how do I stream http request...
In that, users are uploading files and I want to report on a perotic basis how many bytes have been read/received so far.
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 have a database which signature images. Images are saved in binary.
I want to retrieve the image and display in an image control. I am kinda new to ASP and what seemed so simple has suddenly become a real problem.
The at the botom is how I would do it on a winform. Unfortunately I have no picturebox control in .asp. So how do I get the image stream into image1.imageurl?
Is there a way to put the stream into a session variable and then point to that as a url?
for instance replacing the last line below with this and then pointo to it from image1.imageurl?

I there a way to know if a request is a soap request on AuthenticateRequest event for HttpApplication? Checking ServerVariables["HTTP_SOAPACTION"] seems to not be working all the time.
public void Init(HttpApplication context) {
context.AuthenticateRequest += new EventHandler(AuthenticateRequest);
}
protected void AuthenticateRequest(object sender, EventArgs e) {
app = sender as HttpApplication;
if (app.Request.ServerVariables["HTTP_SOAPACTION"] != null) {
// a few requests do not enter here, but my webservice class still executing
// ...
}
}
I have disabled HTTP POST and HTTP GET for webservices in my web.config file.
<webServices>
<protocols>
<remove name="HttpGet" />
<remove name="HttpPost" />
<add name="AnyHttpSoap" />
</protocols>
</webServices>
Looking at ContentType for soap+xml only partially solves my problem. For example,
Cache-Control: no-cache
Connection: Keep-Alive
Content-Length: 1131
Content-Type: text/xml
Accept: */*
Accept-Encoding: gzip, deflate
Accept-Language: ro
Host: localhost
mymethod: urn:[URL]
Some clients instead of having the standard header SOAPAction: [URL], have someting like in example above. "mymethod" represents the method in my web service class with [WebMethod] attribute on it and [URL] is the namespace of the webservice. Still the service works perfectly normal. The consumers use different frameworks (NuSOAP from PHP, .NET, Java, etc).
My query is that I have an sql field for image with db type "Image" , now I have successfully inserted some images in the form of bytes, now how to read those bytes of image from database and convert, show in gridview?
View 1 RepliesI'm implementing a custom page caching solution and I don't want the request to be cached or retrieved from the cache if it's in response to a form submission or some sort of asp.net postback.I'm trying to figure out if the current HttpRequest is a postback. Is there a way of doing this outside the context of a page or other usercontrol? In otherwords if I'm inside an HttpModule I don't have access to this.IsPostBack but I still need to determine if it is in fact a postback.
View 5 RepliesI have several configuration entries for application.
Identical entries are stored in Machine.config/Web.config etc..
How would I determine which one is read at run time..
I have denied anonymous access to the entire application using the following Web.Config setting:
<authorization>
<deny users="?" />
</authorization>
Then, for various paths, I have allowed anonymous access using Web.Config settings such as this:
<location path="Home/ShowLogin">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
I'd like to be able to determine during the processing of a given request whether the requested URL is to path that allows anonymous users or whether the request is to a path that denies anonymous users.
What is the most elegant way of determining this?
Given a set of uploaded files in Request.Files, how do figure out which form field yielded which file?
I have a generic form emailer that various forms post to. This file generates an email of the name/value pairs contained in the form post. I'm trying to add support for uploaded files such that the table of name/value pairs will show the name of the file upload element and the name that the file was saved as.
However, I can't figure out how to link that information together. HttpPostedFile doesn't contain any information about the HTTP request (like which field name was used), and Request.Form doesn't contain any entries for uploaded files.
So while I can easily upload the files, I don't have an easy way to generate an email saying "this uploaded file was for this field, and this uploaded file was for that field".
I am having trouble finding any information on this but basically in MVC how do I set up a controller method do read a GET request? For example I have the following url,
http://www.mysite.com/events/eventsearch?sdate=31/10/2010&edate=31/12/2010&group=3
Do I just do the following?

I just do not understand how to handle the GET requests in ASP MVC.
I am using an Zencoder API to transcode video files. Once the job is completed they will do a HTTP POST with XML or JSON data containing the Job ID and other info to the url we provide.
So if URL is www.abc.com/GetZencoderResponse.aspx or .ashx, how can I read the data they post?
excuse me for the underlines, i thought that would make my query stand out.
I have checkboxes that I have created using Literal now on postback I get the checkboxes which are checked in the Request.form.Allkeys. However I don't know how to read those values how can I use them? how can I count how many values are in there and how can I find some values in there example I want to find if the request.forum.allkey contain forumaName0 ..
View 1 RepliesI'm in a situation where a GET request is made of my server without any content-length header. After the GET request is sent the client then sends a small chunk of data (8 bytes to be exact). It's imperative to note that this data is not meant to be treated as a request body. For this reason asp.net/iis ignores it. I cannot read it and the input stream says it has a length of 0. This is the correct behaviour!
What I need to do is somehow hook into the request processing pipeline early enough to read this data and somehow append it to the request (Items?) I don't know how to do this 'correctly'. I figure I should probably create an IHttpModule to check if the request is of the type that will have this data, then somehow read it.
How would I go about this? How would I be able to read this information in from the stream? I've tried adding an event handler to HttpApplication.BeginRequest but everything I try to read the stream fails. I've read that I could potentially add a custom header using reflection (this would allow me to add a content-length header) but this feels nasty and hacky - I presume there's just a place where I can hook in and handle the reading of the stream before passing it on for further processing.

View 4 RepliesIn 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?

View 3 RepliesI need to find a way to accurately calculate the byte size of the text inside a particular textarea. I am working in .Net so I have access to those libraries, but I'd prefer a Javascript solution. How many bytes is each character worth? What would be the most efficient way to count and multiply? Or am I missing a better way entirely?
Edit: I'm attempting to determine the download size of a piece of Javascript that has been pasted into a textarea. The closest thing I could find to this is ][URL]. I don't want to just lift their code, especially since I don't fully understand it.
i declared byte array in my function
Try
Dim bytes As Byte() = New Byte() {}
If Not fupload1.PostedFile Is Nothing Then
Dim myfile As HttpPostedFile = Me.fupload1.PostedFile
' Get size of uploaded file
'here how to allocate bytes array variable already declared
Using the FileUpload Control, I know I can get the size of a file using: PostedFile.ContentLength. Using VB, is there a way to show Bytes being loaded in Real Time? In other words, if 1000 bytes has already been loading, a Label will show 1000, when 4263 bytes has been loaded a Label shows 4263, etc.
View 2 RepliesI 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 gridview with a Download button that serves a download to a user. I put it in App_Data so its secure so people can't try to download it. However, when I use this code, the save as dialog box pops up, and when i hit save as, the file immediately finishes loading - and it's just 0 bytes. The file is 5 Megabytes.
