I have creted a form for a job submision it has a number of text boxes / date pickers / text edittor and async file uploader, onload it creates a random string and stores it in a text box (this becomes the job id) this id is also used to create a folder (of the same name) to store any file uploaded, I have tried to store the file location so I can add it to the database but the textbox/lbl remain empty.Secondly I would like to submit this form to a database I am using asp.net 3.5 with rules / membership / state on sql I would like to be able to post the user role / name as part of the data store if this is possible.I have attached my code the asyncfileUploader was converted from C# Demo and modified using suggestions found via google.

the code seems to function fine apart from not returning the uploaded file location (so it can be downloaded via a link later)

I am develping an application that integrates with an RFID kit. The problem is, the kit comes with an .cs class that accepts data stored in a byte array however, each information stored in the array respresents an int. I wanted to store String information in each array but, my research suggest that a String itself can be converted to a byte array and not a byte....here the code from the .cs class:
byte BlockNo = 0;
byte[] BlockData = new byte[16];
byte ReturnCode = 0;
[code]....
Each t_b*.text respresents an int. Is there a way I can stored a String in a single byte block?
I am working in a school and we recently installed a new server running WinServer 2008R2. I want to be able to point people to a URL on our intranet and have them fill out a simple registration form and have this data written to a database. It would also be nice to have some data auto-populate (such as their name).
Is it overkill to set up a sharepoint server and try to do this with Access Webforms? Could I use something like dotnetnuke and find a module that works? Or how about options for writing custom forms?
I am getting a FaultEvent when trying to send form fields through HTTPService that contain more than 542 chars.
Initializing the HttpService:
httpServ = new HTTPService();
httpServ.method = 'POST';
httpServ.url = ENDPOINT_URL; //http://localhost:3001/ReportError.aspx
httpServ.resultFormat = HTTPService.RESULT_FORMAT_TEXT;
httpServ.contentType = HTTPService.CONTENT_TYPE_FORM;
httpServ.addEventListener(ResultEvent.RESULT, OnErrorSent);
httpServ.addEventListener(FaultEvent.FAULT, OnFault);
Sending the request:
var params:Object = {};
//params["stack"] = e.stackTrace.slice(0, 542); //length 542 = works
//params["stack2"] = e.stackTrace.slice(1, 543); //length 542 = works (just to show that it's not about the content itself)
params["stack3"] = e.stackTrace.slice(0, 543); //length 543 = fails
I also seem to be able to create many form fields (with 542 length) so that it's not a limit of the request itself but of the form field:
var params:Object = {};
params["stack"] = e.stackTrace.slice(0, 542); //length 542
params["stack2"] = e.stackTrace.slice(1, 543); //length 542
params["stack3"] = e.stackTrace.slice(2, 544); //length 542
// Length > 1600 chars

I created a New Project ASP.NET Web Application.
I created a Textbox named VisitorName. The visitor puts in their name and it goes in VisitorName.Text
There is a Label that says "Which do you own?"
There is a RadioButtonList. It has Cat, Dog and None.
There is a button that says Add to list.
The button needs to add the results of the above items and put them in the list.
Now you keep adding people and their pets.
Once there are all entered you press send and I get the results for everyone entered during that session via email.
I have no database access and the information does not need to be stored in such a way.
I would like to use a datatable or datalist or something to that sort.
Oh and I would like the visitor to be able to click on a name in the table and edit the data using the form controls not in the datalist or datatable itself.
I'm building an application that processes application forms. I'm hoping I can get an advice on how to approach it properly. There are 4 forms right now but it will have a possibility of having more. Most of them have the same fields but each have 4 or 5 items not existing within other forms.
