I am looping through the posted values on a form with a view to doing something with them (so don't have access to the controls themselves). This is the process I have to take on this project so that is why I'm doing it this way.
On the form I will have a file upload box but I am not sure how I would upload the file that has been selected from it as I can't just do Control.SaveAs(). When I return the posted value using Request.Form.Item[i] I get the file name I chose but not the full path like I would expect.
I'm using a asp file upload control, however, when other controls trigger some post back actions, the file upload value return to null...any sample code i can follow please?
I'm trying to upload a file to an ASP 2.0 web service through HTTP 1.1 POST from a client-side application. If my web service function is declared as
<WebMethod()> Public Function UploadFile(ByVal file as Byte(), ByVal fileName as String) as String ...
The test form says the request should take this form:
POST address_of_service HTTP/1.1 Host: <host> Content-Type: application/x-www-form-urlencoded Content-Length: length file=string&file=string&fileName=string
How do I get my binary file data into that form? I've tried just converting the file data to a string and putting it in the body (file=<string_data_here>) but I get HTTP 500 errors back, complaining about not being able to convert it to System.Byte. I've got HTTP POST working fine elsewhere in my application with plain string parameters. Also, out of curiosity, why is it showing the file parameter twice?

The usee then fills out the rest of the form and then saves the document.With the image extraction, I was owndering if it was possible to do that as an ajax post. The other submit button can work as a normal http post

I have implemented a generic handler to work as a restful web service in ASP.Net. I have a problem receiving the XML file that is being posted to this web service. I cannot actually see anything being passed. I have gone through the form, querystring, and file properties of the request object. Everything is empty. I know that the file has been posted correctly because I can see it while using a port sniffer.

I'm well aware of how to get files from the client to the server using standard ASP.NET techniques, however, I have a need to be able to retrieve data from a third party web page written in basic html and process the file data in an asp.net web application.
How do I retrieve the file data in the page referenced in the action attribute of the form. So far I have tried the code below, which allows me to access the file name - but not the byte stream of the file.
protected void Page_Load( object sender, EventArgs e ) { string fileName = Request.Form["fileUpload1"]; // No files appear in the request.files collection in code below. foreach (string file in Request.Files) { HttpPostedFile hpf = Request.Files[file] as HttpPostedFile; if (hpf.ContentLength == 0) continue; string savedFileName = Path.Combine( AppDomain.CurrentDomain.BaseDirectory, Path.GetFileName( hpf.FileName ) ); hpf.SaveAs( savedFileName ); } }
I was referring muddasar's one of the article for the validation. Below is my code and i am trying to validate the file upload selected file format on the submit button. I have 4 upload control and fu1 is mandatory field and others are not mandatory fields. Though i need to validate all the four uploads if the files have been selected. My full sample code is below for easy testing,
I am doing slight mistake on the return to the main function. if i test indvidual function it works fine. whereas if i include the 4 functions in one function with the return statement, it's not validating. goes to to the server.
I have a website that uploads different file types, creates thumbs from the files and saves the file and thumbs to their respective folders. every so often it throws an exception string or binary data would be truncated, Ive never encountered this locally. I have a problem pinning down the circumstances that it happens, I thought it was documents with spaces in the name but that works sometimes as well. This is really bugging me and I need to fix this. The db table fields are long enough, trust me . Has anyone else ever encountered this issue?
I'm using a DetailsView control and have a FileUpload control in a TemplateField for uploading images to a database. However, I'm not sure how to take the image name e.g. Button.png as a value and enter it into the database.
