View 4 RepliesIn my application Im saving multiple files(image,pdf,txt) to a folder. Suppose I have an image with name "image1", if this image already exists in the folder and if another user tries to add another image with the same name "image1" then, it should give message to change the File name.
I had used below code:
string filePath = DamRep_FileUpload.PostedFile.FileName;
string filename = Path.GetFileName(filePath);
string contenttype = String.Empty;
if (contenttype != String.Empty)
{
if (File.Exists("~/FTP/File/"))

but its not working.
I am using the fileupload control to upload an excel file to a server, but I am getting a
"Access to the path '\<server>importResponses.xls' is denied" when I try to use fileUploader.SaveAs(filepath). The filepath I use is \<server>importResponses.xls, so I am actually saving it to a share on a different server.My environment consists of a web server and a database server. I am trying to upload the excel file to a share on the database server. A stored procedure then takes that excel file and imports the data from it into a table. So the problem isn't with being unable to save a file to a share on the web server, but it's a problem with being unable to save a file to a share on the database server. It used to work, but now it doesn't and I have no idea why. What process(es) on the database server do I need grant write access for in order for the fileupload control to successfully save the excel file?Right now, I only have the Network Service account with read/write access to the share on the database server. I tried adding other accounts, such as the ASPNET and IUSR_<server name> accounts, but nothing seems to work.The web application that does the actual uploading is configured like this:
<authentication mode="Windows"/>
<identity impersonate="true"/>
Could that have anything to do with it?If you're asking why I'm trying to save an excel file on the database server instead of on the web server, this was the only way I got this to work. If anyone has a better suggestion on how to programatically import excel data into a SQL table, I am all ears.
I have a question about saving an image file with it's thumbnail in vb.net.

View 1 RepliesI am experiencing the following page error when trying to use the FileUpload control on my web page to upload files larger than 3MB or so. The error is as follows:"Problem loading page The connection was reset The connection to the server was reset while the page was loading.
* The site could be temporarily unavailable or too busy. Try again in a few moments.
* If you are unable to load any pages, check your computer's network connection.
* If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web."I suspect this may be due to a timout issue. If so, how can I increase the timeout period for this control / process? I am coding in VB.NET.

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 big excel file , and i want to upload it to server.
on upload_click , i have to do a processing which takes very long time,
because i am finding latitude and longitude from the google by reading that excel file.

i have created a thread on upload_click and doing all this stuff in that thread .
when user clicks on CANCEL , i am aborting that thread.

I am working on a comparison tool that will take an excel file and a .csv file and find differences. The user is going to be selecting the two files from their local machine via the .NET FileUpload control. The issue I am running into is that I don't want to write the files to the server first so using something like below won't work for me, as "Book1.xls" or even " + FilePath + " in place of it won't work. I need to be able to read the posted files into memory, then create maybe datatables of them, then do my comparison code.

View 1 RepliesI'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));
}
}
}
}
