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?

Possible Duplicate: How do I Validate the File Type of a File Upload?
i would like to add file extension for filtering to file upload control in my asp.net page.and do validation on client side.how can i set file extension dynamically..ex:images only(.jpg;.png;*.gif;).
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,
<asp:FileUpload runat="server" ID="fu1" />
<asp:Label ID="lblMessage1" runat="server"></asp:Label>
<asp:FileUpload runat="server" ID="fu2" />
<asp:Label ID="lblMessage2" runat="server"></asp:Label>
[code]...
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 to copy a file from client machine to server folder without use file upload control.
i tried with WebClient().Like this
Dim onbjweb As New WebClient()
onbjweb.UploadFile(Server.MapPath(serverpath), "POST", LocalFilePath).
Its working fine in localhost.When its deployed in server its not working.
I would like to restrict what they see in the file upload dialog, which is set to "All Files" by default. I understand how to validate that they only uploaded a certain file type, that is not the question here. I would just like to know how to default the file type in the file selection dialog.
Is there any way to change this to "PNG only" or "*.png"?This is using AsyncFileUpload in the ASP.NET AJAX Control Toolkit.
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?

How to set default file in <asp:FileUpload />
When a FileUpload is null then i want to set defualt file .
regarding my code :
Byte[] imgByte = null;
if (FileUpload1.HasFile && FileUpload1.PostedFile != null)
{
HttpPostedFile File = FileUpload1.PostedFile;
imgByte = new Byte[File.ContentLength];
File.InputStream.Read(imgByte, 0, File.ContentLength);
}
Our problem/question revolves around an upload control that loses the selected file (goes blank) when a postback control is used (in this case, the dropdown list posts). Any insight into what we are doing wrong or how we can fix this? Below is our code and a summary of the problem.
<asp:updatepanel id="UpdatePanel1" runat="server">
<ContentTemplate>
<div class="row">
<asp:DropDownList runat="server" AutoPostBack="true" ID="CategorySelection" OnSelectedIndexChanged="CategorySelection_IndexChanged" CssClass="drop-down-list" />
</div>
<div id="SubCategory" class="row" runat="server" visible="false">

View 1 RepliesI want to upload a file without using the file upload control in asp.net.

document.getElementById("fileUpload").value = "C:myImage.jpg";
document.getElementById("btnUpload").click();
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))
{
WebHeaderCollection headers = response.Headers;
foreach (string key in headers.Keys)
{
Console.WriteLine("Response Header: {0}, Value: {1}", key, headers.Get(key));
}
}
}
}
I have form for update product in which I have file upload control, in update product form i have retrieved all other details of product in appropriate text boxes like product name,price,etc. I also want to retrieve name and path of product image in file upload control which is uploaded using add product form. Is it possible to set path of uploaded file to file upload control.
View 1 RepliesI wrote some code to upload files to amazon S3, if I put a full file path manually It successfully uploads the file from my computer. What I'm trying to do is use a file upload control and store the full path in a variable so that I can use it for my amazon method. Ive read everywhere it seems that the browser won't let you get the full file path for security reasons.
How can I get the full file path? Should I just store the files on my webserver and point my amazon method to the server path, and then use the file upload control to tell it what the filename is?
When I am trying to save a file using asp.net file upload control. I am getting Access denied issue.
