View 3 Repliesi did this code to upload file and displaying it in the image:
[Code]....
the code works good. the file is uploaded under my website here in the solution explorer: now after uploading the file,the newly uploaded file is shown in the image(since there were a few more images present in the same location but they were not shown by the image) i used this url to the imageurl:
ResolveUrl("~")
which returns me this:
WebSite1
now my question is why the newly uploaded image is shown in the image? there were several other images present at the same location and even i have not used something in my code that tells to show only the newly added image from my website into the image.
How to add watermark to uploaded doc (pdf or image files).The workflow will be-User register at portal -> user upload some required document (like financial proof or some kind) -> When saving them to database -> a watermark (predefined by admin at backend in admin panel as - Logo or Text) will be added to those uploaded document on top and bottom or wherever possible on the uploaded document.
So in future when admin views the document uploaded by him in his account, it will be displayed with stamp or the watermark. It will prove that the document is uploaded to server by user or whatever. Now, this we have found way to do in jpg, but in case of pdf its quite tough..

I create a new class FileUpload for my web page. In onload method of page, i create a new object of that class and after file uploaded, i fill some information of file to that object(name, size, extention,type). I create a method in class to delete that file. But When i use it, the error "The process cannot access the file 'D: emp25.jpg' because it is being used by another process." is appear. I thinks the object is using the file uploaded and i can't delete file.What's the problem and how can i solve it? I need to delete file.
View 5 RepliesUsers can upload files to the server, which are stored effectively forever.
A few of my ideas involve logging every upload, but then the files are usually referenced in html which isn't easy to track.
Files can sit unused but still be referenced. I could do a fuill text search on these, but that's pretty brute force.
My system Uploads files to an IIS server and then i manipualate them and after finished doing every thing, i need to delete the original file, the problem is that the IIS "grabs" the file and i can't delete it, when i close the procces i can delete it manualy from the server, but until i close the procces i can't even do that...
I'm using:File.Delete(Server.MapPath(OriginalFileVirtualPath)); to delete the file.
p.s. for now i'm using the .net server, not a full active IIS, but i don't think that the problem is over there...It even make some sence that when i upload a file to the sever, it won't let to delete it strate away, but i'm sure there is a work around...

FileUpload2.SaveAs(Server.MapPath("NewFolder1") +

View 2 RepliesI'm trying to use an asp:FileUpload Control to allow users to upload files (.doc, .gif, .xls, .jpg) to a server that is outside of our DMZ and not the Web Server. We want to have the ability to look at these files for viruses, structure, etc prior to saving them into another directory that would allow access to outside users. From what I have read about this control is that it will allow for files to be uploaded to the web server. Can this control be used to upload files to a server other than the web server? If it can be done where should I look for this type of functionality or how do I force it to go to https:servernamefolder name (Where server name is not the web server)? Would I have to read the file then write it to the other server?

View 1 RepliesI just inherited an ASP.NET WebForms web application that I was tasked with refactoring. One of the features is a file upload and while debugging I noticed that as soon as a file is posted to a certain page/handler, it is automatically uploaded to the root directory of the application. The file is then moved to the proper location. I can't seem to figure out whats causing this automatic upload of the file. Is there something I'am overlooking in ASP.NET WebForms that allows this to happen? Is it an IIS configuration or something?
View 1 RepliesI recently published my website locally and then uploaded the .aspx files to the root directory of the host server and then uploaded all of the compiled files into a new "bin" subdirectory. But, when I accessed my website through my domain name, I got an error message that said that my Default web page has not been compiled.
The service that I am using is an ASP.NET hosted server called JodoHost. But I noticed that, besides the new "bin" subdirectory that I put all of my compiled files into, there was also subdirectories named aspnet_client, cgi-bin, and images. I assume that my problem stems from not placing my compiled files into these. Is this correct? If so, what should I be placing into which directories?

I am getting this exception few times a day in our website.The page that create PDF file from the uploaded image files result in above excption.
I'd like give unique name for uploaded files in a folder.
I know we can a uniqueidentifier to file name but I think it isn't a good way.
I have a page that loads a two different files that the user uploaded during page_load. The code is an example I used from the aspsnippets site. The files are stored in a server folder while the location is saved in the database. The code below gets all files in the folder and binds them to a gridview.
Dim filePaths() As String = Directory.GetFiles(Server.MapPath("~/Uploads/2012/emp/"))
Dim files As List(Of ListItem) = New List(Of ListItem)
For Each filePath2 As String In filePaths
files.Add(New ListItem(Path.GetFileName(filePath), filePath))
Next
gvEmp.DataSource = files
gvEmp.DataBind()
What I want to do is to get only one file per user as the fileID along with the location is saved in for every user. I ran a query to get the fileLocation and pass that location stored in the database instead of the current server path but I can't figure out how I would do it.
I've got a FormView control on a page. Its default mode is insert, since the intent is to have the user enter a record, save it, and then do something else. I've written a stored procedure to insert all of the data into 5 tables. 1 of the columns inserted is default, in SQL Server 2005, as an INT column, which is an IDENTITY column. After it inserts the record into the primary table, using a secondary stored procedure, it retrieves the newly created INT value, and then the primary stored procedure inserts records, using the new INT, into the other 4 tables. This is working fine. The primary stored procedure, which is called by the SqlDataSource on my .aspx page, defines this parameter as an output parameter:
[Code]....
In the FormView's ItemInserted event I'm trying to get the value from the FormViewInsertedEventArgs e parameter like this: [Code]....
However, the result returned is 0. Huh? That cannot be, because the new INT value created is something like 145000. Why am I then seeing a value of 0?
