1. what is streaming how we download File through Streaming. 2. what is service Behaviour and operation Behaviour In servic Contracts . plz Explain Me In brief
I'm having a problem with file streaming where this file is a video that is streamed to a FLV player.
Essential components for understanding the problem:
- An asp.net page called Viewer.aspx that has de FLV player incorporated in the HTML.
- An asp.net page (It could be an http handler but in this case it's not) called Downloader.aspx that gets a flv file from somewhere on the web and writes it to the Response Output Stream.
Everytime Viewer.aspx is called, it makes Downloader.aspx the source of the the FLV player and the video is correclty presented and streamed into the player.
The problem I am having now is that any user interaction with the page (even typing an URL inside the same website domain on the browser address bar) becames hung until the video download ends.
I can measure this video download with HTTP Watch for example, and confirm that just after the video download into the player ends, the command issued by the user is immediately processed (or the browser goes to another page if the user typed a new address in the browser address bar).
I tought that it could be the limit of 2 connections per domain, but HTTP Watch only shows one active connection (the video download into the FLV player).
Even if it was this 2 connections limit, I think a nice solution would be to somewhat detect the user interaction with the page and abort that video download.
I am using VS 2010 and C#. I am trying to create a pdf file in web application. I am trying to convert a dataset to pdf file. The pdf file is getting generated, but when i try to open the pdf, i am getting the error as "Adobe reader could not open "sample.pdf" because it is either not a supported file type or because the file has been damaged" How to fix this?
I am building an asp.net application, using II6 on windows server 2003 (vps hosting).
I am confronted with an error I didn't receive on my development machine (windows 7, iis 7.5, 64 bit).
When my wcf service tries launching my query running against a local sql server this is the error I receive:
Memory gates checking failed because the free memory (43732992 bytes) is less than 5% of total memory. As a result, the service will not be available for incoming requests. To resolve this, either reduce the load on the machine or adjust the value of minFreeMemoryPercentageToActivateService on the serviceHostingEnvironment config element.
I have both VS 2005 and 2008 installed on my machine. 2005 is fine. For 2008, literally any asp.net project I try to create gets this eror. I try stepping into the code, and the error occurs apparently before anything that I can trap is loaded. There is no information written to the event log. I have tried this with a "Hello World" webpage with nothing else going on. Seems unique to my Windows Server 2003 machine.
I am getting a weird error in asp.net while using leadtools imaging api. Here's the stack trace.
System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at SetThreadData(_THREADDATA* ) at Leadtools.Codecs.CodecsOptions.Use() at Leadtools.Codecs.RasterCodecs.DoSave(SaveParams saveParams) at Leadtools.Codecs.RasterCodecs.Save(RasterImage image, Stream stream, RasterImageFormat format, Int32 bitsPerPixel)........
I am maintaining C# .NET code written by somebody else, I get following exception few times,Attempted to read or write protected memory. This is often an indication that other memory is corruptThe code structure where I get the above exception is somethign like this,- it is using ref variables in following sequence,Variable-1 and variable-2 are local variables in App1, - App1: func1() which passes these variables reference to func2(), - App1: func2() passes same variables reference via .net remoting to another application (App2).-App2: does the same passes same received reference to another call 2 times.- The execption is occured while returning from App2.
(App1:func1(ref Var1, ref Var2) --> App1:func2(ref Var1, ref Var2) <---App1 .net remoting to App2--> App2:func3(ref Var1, ref Var2)--> App2:func4(ref Var1, ref Var2)-->variables getting updated and function returned to original caller)
My doubts are ,1. Is passing reference variables in such chain is correct? will it cause such exeption? Does .net support ref variable call directly?
Which storage method should I use when using ASP.NET Charting Tools? I'm currently using memory, because it seems like the most straight-forward and easy to implement option. Is there any reasons I should be aware of why I should choose one of the other options? The charts generated will be useful only for an overview kind of purpose (checking to see if a data collection is following a certain pattern, as it is being built day by day), and this function won't be used frequently.
So I'm working on a site that is going to need a file upload control where the user would be able to upload an image, and then the page would postback causing the image to appear for their viewing (before they submit the data to the database, the image is being stored as type image). What I do now is have my own private web form where people send me their image, I format it accordingly and use the following simple code to upload it:
byte[] newimage = fileUpImgFile.FileBytes; var myDataTable = (from item in context.TypeSet where item.Number == txtBxNumber.Text.Trim() select item).ToList(); foreach (Type item in myDataTable) { item.Photo = newimage; } context.SaveChanges();
Which works, but in this case, it would only work if the record exists already in the database so the person would have to save the data, then go back in and upload the image (inconvenient and inefficient). Is there a way to upload it, store it in memory, and then display it, without saving it to the database?
How can i Make A Text File In Memory(Ram -> Save NoWhere) And Write Something On It And Open NotePad on top of Client browser And Open That Text File In It And Let the user save it by him/her self? -> in code behind
How do I create a text file and write the contents of a string to it? I plan to reference to the text file later. It could be on the server (root folder) or anywhere where I can reference it. Below is the string contents
foreach (string s in strValuesToSearch) { if (result.Contains(s)) result = result.Replace(s, stringToReplace);
I am dynamically generating a file from server based on user input. I need to provide a download button which, upon clicking, downloads a file to the user's file system. Also, the user might click the same button twice, upon which the file should download again.The dynamic generation of file rules out the HttpResponse.TransmitFile() option, which suports mutliple download.Almost every other option I have come across needs Response.End() to be invoked, which prevents a second download.How do I satisfy the 'multiple download" requirement?Read up on Virtual Path providers, which might enable me to use TransmitFile(), but that looks like an overkill for such a simple requirement.
What are the options for handling file uploads to reduce the memory footprint? Is there a way to upload in chunks? Is there a way to stream upload directly to disk instead of loading entire file in server memory?
I have a memory leak somewhere that I cant find. Every few days my server will crash, and just before that I log a ton of SQL errors stating that it is "out of memory".
I cant find it anywhere, all of my connections are being disposed like so:
[Code].... Then I call the connection from my pages like so:[Code]....
That is all pretty straight forward. The connection is disposed because it is implementing the USING clause. I am opening the connection in my connection manager class, and not where it is being utilized?Or, could the problem be in the below method I am using to populate a SqlDataReader:[Code]....
Now, at first it appears as though this could be the problem because the Connection isn't part of a USING clause, however doesn't the 'Data.CommandBehavior.CloseConnection' pretty much do the same thing. This makes sure that the connection is closed when the reader is closed, right? Here is how I call that above reader from my login page code behind:[Code]....
So the DataReader will get closed even without the .Close() because it is in the USING, and the connection should get closed because I specified it in the ExecuteReader paramters right?
I have a memory issue on my websites and am trying to get to the bottom of it. I have downloaded the 14 day trial of ANTS Memory Profiler and have been playing with it to get a grip of what it's telling me. In the memory options on the timeline, I can see Bytes in All Heaps and Private Bytes etc but I am not sure which ones I should be focusing on to see where the memory spikes and doesn't go back down.I am profiling a ASP.NET website using ASP.NET 2.0.
I am working on a web app that will heavily rely on configuration. The configuration is also will be written by another process or human. I am looking to get response on best practices in .net 3.5 on how to implement this case. I had used the configuration section of an early version of the Enterprise Library Applications Block. I really liked working with it but from what I hear it is discontinued in current versions. Hence the question... Need to be able to serialize collections, pick up file write event to reload new instance of config into memory.
I know this is probably a pretty easy thing to do and it is if I can upload the file and store it onto the hard drive of the server. What I need to do is read the text file into memory and then parse through it one line at a time. Anyone have any code that demonstrates that?
I am trying to play a video file in an aspx page. the video resides in the database.
I am using handler file (ashx) for that, and using the ashx file as src value of embed tag in the aspx page.
[Code]...
it works if I use media player activex ( object tag) . but it does not work for FF. I think embed tag is most standard. so i am trying to use it for streaming video.
