AJAX :: Verify Whether File Exists When Uploading Using FileUpload Control
Mar 17, 2014
In 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 sometimes, I have only 1 Point to display or nothing at all on the Chart. So I'd like to check If there are some Points before to put the color of each Point.
For example :
if (ChartAlertes.Series[0].Empty == false) { //... }
I am uploading an excel file ( containing int values )using the fileupload control. I need to work on one entire column in the excel sheet.I want to copy contents of the file either in an array or a table and then work on it.Can anybody suggest a better way of working on the excel since .
according below thread I change file name when users upload from file upload control:
[URL]
below is my code that I changed if(this.fuppdf.HasFile) { string path = Server.MapPath(".") + "../image/House/article/pdf";
[Code]....
if file name be duplicate it add 1 at the first of file name but here it doesn't  work I mean when I upload file i.e catalog.pdf ("catalog is the text in txttitle) it saves in the  host with this name catalog.pdf
but when again I want upload catalog.pdf in host it overwrite last (catalog.pdf) but I want if there was catalog.pdf file it saves with this name 1catalog.pdf in host
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:
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.

Does anyone check the domain of an email address as part of their verification steps? eg. Confirm that gmail.com exists if the user specified blah@gmail.com as their address.
I should note that in my webapp an existing user can forward invites to their friends. I have no need to verify those invites at all. Rather, I just want to warn my user if a typo etc. may be sending an invite to the wrong person. Is this even worthwhile to do?

I have a user control in which i am using File upload control for uploading file.
I have used ModelPopExtender here for showing it in popup.

I 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.
