Web Forms :: Implementing Reliable File Upload Functionality Without Using Client
Sep 26, 2010
I want to have an upload functionality for uploading large files -- as large as 1GB. I see some sites successfully implementing reliable upload functionality without using any upload clients e.g. ActiveX, Java, etc. Some suggest, the secret is sending the large file in smaller and more manageable chunks to the server. If that't the case how do I handle that?

I want to implement a forgot-password feature in asp.net mvc that allows users to reset their password, and have some questions in this regard: Lets say that before allowing users to reset their password, I want to verify some extra information such as their first and last name. This info is not stored by default in the table created by aspnet_regsql. What is the recommended approach to address such issues?
Should I store this kind of info in a separate table, and use table joins to verify OR should i modify the schema of the table generated by aspnet_regsql (how?) so that I don't have to use joins? Do I need to write a custom provider OR would that not be necessary? I have read at places e.g. in this post that instead of emailing a temporary password, an alternative is to email a URL that when clicked allows users to change their password. How is this done? How to ensure that the URL expires after 1 hour?

We have a requirement to allow the cient to upload multiple files which resides in a single folder, within the client computer. To do this can we allow the client to browse for the file location and select a single file (via a normal asp file uploader), and then recursively read the necessary files from the relevant directory? Is this possible or is there any other way to do this?

How to upload the file directly from the client machine. I have one button for mail sending.
If i click the button, the from, to, subject comes using pageload. Like that the default file also could be added as a attachment directly from the client machine.

I'm considering going at this myself because my requirements are particular and highly customized:
The grid is bound to a collection of complicated objects, each of which may contain child and grandchild objects. Depending on data and context, the template'd cells vary from TextBoxes to ComboBoxes to Calendars to a combination of controls.TextBox cells have Google-style auto-complete functionality. Also each TextBox cell can expand into a small TreeView pane that allows hierarchy-navigating selection of a value should auto-complete be insufficient.Values from other controls can be drag-and-dropped into cells.Columns are re-sizable and re-orderable. Clicking their headers sorts data.All of the above is AJAX / client-side / Web 2.0 of course.
Has anyone built anything similar from scratch? Or used an effective tool to accomplish this goal? How well would Telerik meet my specs? Is it right to have the hunch that something this specific is best done by taking a Microsoft GridView and extending it myself?

I want to upload file at client machine using fileupload control. How can I do this in asp.net.. Currently I am using the following code to upload a file. but this code gives the contents of file at server machine..
I need the full file path..In IE versions higher than 7, FileUploadControl.PostedFile.FileName gives only the filename ..
string filename = FileUploadControl.PostedFile.FileName;
sr1 = new StreamReader(FileUploadControl.PostedFile.FileName);

i am trying to create an aspx page where i can directly upload a file from the client to the server without user intervention. I would like to do something like when the user specifies the file path in the url, that particular file must be uploaded to the server.
example: ht.tp://XXX.XXX.XXX.XXX/File_upload/File_Uploader.aspx?upload=C:/sample.csv&type=csv
The user can change the value after upload and what ever file he is specifying, it will be needed to be uploaded onto the server which is located at xxx.xxx.xxx.xxx
my sample code is:
[Code]....
this is just a trial to check if the csv file is being created on the server or not, and it is not being created.
i just want to copy the file on the client side to the server side and it has to be only by the aspx page in the format specified above.

I want to access one image file residing in C: of the client's machine. I know with the help of file upload control (or say input type=file), this would be easy. Due to nature of my application (Its a KIOSK application), user is not expected to select file. I am just wondering how should I implement reading file without using file upload control. I want to store this file in Images folder of server. I am beginner to WCF. Should I look towards WCF?

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).

My requirement is to get the file size in client side. there is no problem in FF but in IE you can't do that unless u r using an activeX object. So we thought of putting it in browser cache and reading the file size from there and when we post it to the server we will be taking it from the cache and send it to the server.

I've started some preliminary work on getting a Google-like search functionality into my app - ive never done anything like this before so i thought id be a good idea to run by what im thinking of doing at a high level
1) Using MS SQL 2008 w/ Full Text Search Enabled
2) ASP.NET MVC 2 app is using the Repository pattern, with Linq to SQL for data access I'd like for the user to put in one giant text search value, and the full text to do a search over multiple tables and return a mixed result (Employees, Organizations, Offices, etc)
3) I have a simple stored proc that does a Full Text Search on *one* table that looks like this:
[Code]....
4) My Linq to SQL datacontext calls this SP and which works well enough, i have no inflection or ranking going on but ill add that in later...
Q: How do i handle searching over *multiple* tables, doing some digging around it looks like Full-Text doesnt really allow for searches to span over more than one table - which kinda sucks..although ive seen some workarounds
Q: Is it ok to do a Full Text Search for every table i plan on searching through, and combining the results at the business layer (maybe using rank as sort)? I've heard of things like LUCENE but id really not like to do that at this time.

I am trying to add some client side functionality to a user control that I have written.
A really simplified version of my scenario is as follows:
I have a control called MyControl. This has a javascript method called doSomething that simply shows the current date and time in an alert box.I add an instance of MyControl to a page called WebForm1. I want to be able to call myControl1.doSomething when a regular (non ASP.NET) button on WebForm1 is pressed.
I'm sure this is really simple but I can't for the life of me figure out what I need to do make doSomething available.

I want to upload files to the web servers from the client machines.
Can i upload a file on a network share folder using file upload control?
I would like to create a share folder on a file server sitting next to the web server. If i upload the file from the network share folder instead of uploading it from the client machine does it make any difference?
Will the file be stored in a temporary location before copying to the final destination? Where will be the file stored in this case of uploading it from share folder?

I have a quite advanced application, where I need to add some client/server functionality. Some examples of functionalities is:
Chat
One vs. one fight in a browser game
Draw people on a map
I am creating this application in ASP.NET and AJAX. I do not use Silverlight/Java Applet/Flash or anything else. If possible, I do not want to change this for other reasons.
I thought about creating some kind of game server, and then communicating either web services or TCP protocol: But I have NO idea if this is a good idea. Also, I don't know how to do this.
So my question is:
What's the best way to implement this? And is it even possible? And if it is, could you give a reference or two?

Apropos MSDN link: [URL] [.NET Framework 4 - ASP.NET] Implementing Client Callbacks Programmatically Without Postbacks in ASP.NET Web Pages Using the code from the above link in the following code snippet, if you keep a break point on the statement "if (IsPostBack)" in the Page_Load event.
