View 1 Repliesdoes anyone have any sample code/tutorials on processing a video file uploaded to Azure (.mov, .3gp, .avi) and converting it to flash and also creating a thumbnail file after the video has been uploaded as a blob to Azure?
View 1 RepliesI come from MVC side, where these things make more sense (of course just because I know a bit about it) and my webforms are still sucky sucky.
I got a page where I want the user to upload a file (Excel).
Not too worried about the upload timing out, but after uploading this file will be processed (time & attendance data to be written to the database)
So what I'd like to happen is everything happen asynchronously with the page being updated as the file are being processed.
Also, I'm not sure.. won't I need excel on the server to have my code read the excel file?
I have a .aspx web page and a .asmx web service.I want to upload a file from this web page to my web server so that I can call some web services to process the file, e.g. convert uploaded doc to pdf file.1- how to upload big files?2- how do I process these files automatically? like when i upload on youtube, it automatically does some file format conversion. how can i do this.3- how to make sure that i dont make my user wait on this page , but send email or some type of alert when processing is done.
View 3 RepliesWith the ajax file uploader, would it be possible to check the size of the image before uploading?Currently, it uploads the file to the server and then lets me know that it's bigger than the limit size.
i am using a file uploader to upload files. Now when i am using this on a mobile emulator with default browser IE it is uploading only those files whose name is less than 6 character. the files with name more than 6 character is not uploading through mobile emulator or mobile phone (PDA). I need this solution very soon.

I've dug around in the SDK and managed to connect to my instance of S3, go into my bucket and create an empty file, but can't figure out how to take a file from my computer and upload it. If I have dragged a file upload control onto the designer surface how do I set the properties for it in the code behind?(If I absolutely need to have a 3rd party uploader which should I use). Here is the code I have so far.
static string bucketName = "myBucket";
static string keyName = "sampleKey";
static AmazonS3 client;
protected void Page_Load(object sender, EventArgs e)
{
string accessKeyID = System.Configuration.ConfigurationManager.AppSettings["AWSAccessKey"];
string secretAccessKeyID = System.Configuration.ConfigurationManager.AppSettings["AWSSecretKey"];
using (client = Amazon.AWSClientFactory.CreateAmazonS3Client(accessKeyID, secretAccessKeyID))
{
// simple object put
PutObjectRequest request = new PutObjectRequest();
request.WithContentBody("this is a test")
.WithBucketName(bucketName)
.WithKey(keyName);
S3Response response = client.PutObject(request);
response.Dispose();
// put a more complex object with some metadata and http headers.
PutObjectRequest titledRequest = new PutObjectRequest();
titledRequest.WithMetaData("title", "the title")
.WithContentBody("this object has a title")
.WithBucketName(bucketName)
.WithKey(keyName);
using (S3Response responseWithMetadata = client.PutObject(request))

We are in the process of building a huge site. We are contemplating on whether to do the processing of HTML at server side (ASP .Net) or at the client side. For example we have HTML files which acts like templates for the generation of tabs. Is it better for the server side to get hold of content section (div) of HTML load the appropriate values and send the updated HTML to the browser or is it better that a chunk of data is passed onto client and make Javascript do the work?
View 2 RepliesI added a new report template from the Reporting section of the Installed Templates (rdlc extension). I have successfully created a connection and am retrieving data into textboxes that I have placed on the report. My problem is that I want to do a Test in the Expression template, but I cannot seem to do 'if else' statements. Can anybody give an example of how to perform conditional processing for a textbox on an rdlc page. i.e. The expression for just populating a textbox might be:
Code:
=First(Fields!Actioned.Value, "MyData")
What I want to be able to do is something like
Code:
if =First(Fields!Actioned.Value, "MyData") = "val1" then 23 else 25 end if
Coding for this control seem to take VB/VBA Style syntax.
I'm trying to use a java servlet in a 3rd party tool's web interface (CA service desk) to invoke it's download file functionality using a webclient in vb.net. The trouble is the text stream from response is markup and not the acutual text file stream.
It's like the page is redirecting to another page which actually presents the file for downloading. I have no idea what the redirected page URL is.
Is there a way I can process this redirected page in order to get at the download using a system.net.webclient?
On my current project I have to accept 2 Excel spreadsheets that will be uploaded by clients, process them and create a download package based on this information. This process includes extracting data from the sheets, updating our databases and building several PDF files for the download package. This takes between 15 seconds to 2 minutes to complete, depending on the complexity of the request. Naturally, I want to show some kind of processing indicator rather than just leaving the user hanging while the page loads.
Here's the problem: How to show this processing indicator.
I have to do a full postback to upload the files so this eliminates several nice AJAX indicator methods (sponsoring users rejected the AJAX toolkit async file upload, saying it was confusing to them). If I process on any of the page events during the postback, the page doesn't load until the lengthy process is completed so the browser/site looks 'hung'.
Basically, I need some ideas on how to display a 'building your download' graphic while the lengthy process is working that will also work with a full postback.
We have a very simple ASP.Net page for uploading a file to our webserver. The page has no controls - a client uses it to automatically send us a file each night.
On occasion, the file seems to not get to us, but the client reports that they have sent it.
We added some logging statements to the page, and discovered something quite odd. The page ceases to execute right in the middle of a log statement. No exceptions, just up and dies.
Here is the code-behind:
[code]....
I assume if there was a error in the transmission of the file that either an exception would be thrown from the reader.ReadToEnd() line. And if not an exception, I would expect the page processing to continue but that I may only receive part of the file (in which case it should log something).
The logging statement is only accessing a string variable, and it's inside a try-catch. NLog is the logging component we use, and we access that through the facade provided by the Simple Logging Facade project on Codeplex. So, we trust the logging component to be more or less bulletproof - we certainly don't see anything in our usage of it here that should be causing problems.
Why on earth could this page just up and stop processing like this?
The fact that we get a half-finished logging statement seems to point towards an error being swallowed in the logging system - but that just seems so unlikely - and we have NLog's internal logging on and it is not reporting any problems.
After checking the asp.net version on the web server it seems only the version 2.0 is available and so when I browse to the site i.e. http://servername/site
then I get this error below. Should I put something in the web.config file to solve this issue?It seems the error is to do with the reportviewer control I am using.
NOTE that the ERROR is on line 117Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify configuration file appropriately.
On a web page, I need to allow users to input the path to a file (on shares on servers) - which will be stored in a database so I can subsequently display 'a list of documents that apply to this project'.If I put an input type="file" on the page, it makes it easy for the user to browse to the document ... but, when the form is submitted, the document will be uploaded to the server. I don't want the document, I just want the path.
How would you provide the functionality to allow a user to browse to a file so that you could record the path to the file without actually uploading the file itself?I just want to end up showing, on a web page, a list of files like:
myserverfolder20somefoldersomefile.doc
myserver2folder50somefoldersomefile2.doc
I need to give users an easy way to locate those files in the first place - without having to laboriously open Windows Explorer, find the file, and copy and paste the path. A file upload control gives you access to the path - which is what I need - but I don't want the file uploadedIf I do end up using a file upload control - I don't want to save the file on server - how can I dispose of it so I don't end up with hundreds of temp files?
I'm rather new to the topic of designing web applications, and during my attempts to create something i stumbled upon a rather tricky question. For my application I want to do a user control with which user will be able to select a file from a hard drive and upload details about this file. I dont want the user to send the whole file, just the details about it. For example lets say user selects a mp3 file. I dont want the whole song to be uploaded but i want the details about that song like the Author, on Album etc. Is something like this possible without uploading the whole file?
I tried looking up that topic on the internet but i found nothing... though i dont believe I am the first one with such a dilema;]

I have this concern that I never found out an answer to. If people are on a page on the site that are processing something on that page and at the same time I upload class and/or aspx and .vb page to the server while they are still processing, what happens? Will their data get corrupt? will they be using whatever was there before the new upload until they refresh their page? how does it work?

How to upload a file(any format) into DB columns by changing it into binary format??What data type should we use for it?
View 15 RepliesI am uploading files using HttpWebRequest to an ASP.Net MVC application but, for some reason unknown to me, it is failing to upload consistently.
I know the file is good since if you try enough times it does eventually upload and can be viewed on the server just fine. When it fails, neither the server nor client reports any errors directly related to the upload, the upload just stops partway through at a random location and time and my MVC action method is called without the file being loaded (Request.Files.Count == 0).
This only seems to be a problem in our production environment over DSL. The test and development environment works fine and the production environment works fine from in the office (really fast connection to servers) but fails when running it from home over DSL.
As you can see below, the point where it fails is basic.
