I need to create a custom web control which will be a part of a class library. This custom web control implements the upload functionality. I have implemented this with a web user control where I have a fixed path to a page in the web project where the upload of files take place and it works just fine.
The created control in this class library is used in the web project. How do I post the uploaded file to a page, say SomeClass.cs, in the class library.
Thanks in advance.
You can use a file upload control to post the file to a code-behind file.
Pass the system path as a string overload?
string systemPathToFile = Server.MapPath("~/UploadedFiles/" + Path.Filename(fuFileUpload.Filename));

I want to create a page where I can upload pictures and at the same time bring them to the page.
for example: I have a picture controller which has Index, addpictures in View.
Could anyone please help me?
I am a beginner, so it would be great if you'd write as simple as possible.
Thanks in advance.
You may take a look at the following blog post for a tutorial about uploading files in ASP.NET MVC.
The Path class is defined in the System.IO namespace so you will have to bring that into scope.
If you want to be able to show the uploaded file you will have to store it in some other folder than the App_Data. Files are not directly accessible by clients from this folder. You could for example use the Content folder instead. Once you get the file appear in this folder on the server you could reference it from the view using the <img> tag: <img src="#Url.Content("~/content/someimage.jpg")" /> where you could pass the name of the file to the view from the upload action.
I have an ASP.NET web site, let's call it MySite, and at the same level as the web site, a virtual folder - Data. And in that folder I have the xml file needed in an AdRotator control.
I put "http://localhost/Data/Ads.xml" in AdvertisementFile and I get this error:
'http://localhost/Data/Ads.xml' is not a valid virtual path.
Is there a way to get this working?
The xml file must be on the same website for security reasons, using the control out of the box.
You could write your own methods to read a file from an external server, with an HttpWebRequest for example, then create a server side XML file from that stream and use it with the AdControl.
There is also the AdCreated event to look at, too.
I'm working on an ASP.NET web application for our corporate intranet users. I have a form where a user should provide a path to the file on the local network (something like "\localServer\someFolder\someFile.ext") without uploading the actual file. The issue is that users don't want to type the whole file path and want to use some kind of visual browse dialog.
The standard HTML <input type=file> element allows to browse for a file, but most of the browsers (except for IE) don't allow to access file's full path, so I think it should be done by some external component like Silverlight, Flash, Java applet etc.
I tried to do it with Silverlight, but I'm getting a SecurityException when trying to access file's full path using Silverlight's OpenFileDialog class.
This java applet http://jumploader.com/demo_images.html seems to do something similar to what I'm looking for, but it's focused on uploading files - I only need to be able to get file's full path and pass it to the server as a string.
Any suggestions would be appreciated.
Telerik ASP.NET AJAX RadFileExplorer has the functionality you're looking for:
http://www.telerik.com/products/aspnet-ajax/fileexplorer.aspx
You can use their Custom File Content Provider to hook the GUI to your server's file system.
http://demos.telerik.com/aspnet-ajax/fileexplorer/examples/server-sideapi/dbfilebrowsercontentprovider/defaultcs.aspx
This should be possible with Flash's uploading capabilities. SWFUpload has an API that you may be able to access from JavaScript to extract the selected file name without actually uploading anything. See docs here, for example getFile():
getFile is used to retrieve a File Object from the queue. The file retrieved by passing in a file id (the id property from a file object) or a file index (the index property from a file object).
In a Project I have different modules or folders.In a module I have a namespace called idsobject.I have class in this namespace.
In another CS fle in the same folder I'm trying to access this class.But i'm not able.while if put that cs file in aPP_code than i able to get that class.
how to access the class in another cs file within the same folder.
thanks in advance
In an ASP.NET web site project, *.cs files are only compiled and made available to the rest of the application if they're located in the App_Code folder, or a subfolder in App_Code, or if they are associated with a *.aspx as code behind. The architecture is intended to allow full server-side compilation. You can't just put a *.cs anywhere and expect IIS to be able to find it, compile it, and link it with the rest of the app.
With an ASP.NET web application, you can put *.cs files where ever you want, because they are compiled by Visual Studio using details that are kept in the project file.
I'm guessing that you're using a web site project, which is why it works when you put the file in App_Code.
First check the namespace. If you accessing the correct namespace then perhaps the class access is set to private.
You could give us some extra information.
This sounds strange. Putting a class in a file in a Web project with a .cs extension should work just fine no matter which folder the file is located.
The only thing I can suggest is to make sure that there is at least a
using idsobject;
line at the top of the code unit where you are trying to access the class. The default behaviour for ASP.NET Web forms is for no namespace to be defined, which can sometimes lead to confusion.
The class should be marked as public if you've tried to access it from another namespace.
If it doesn't help, please post here a problematic code snippet.
In my site, user want to upload a pdf file and I have to save it into my own server. I don't need the content to be saved. I want the exact file to be copied into my server where the published file of the site exists.How to do this?
Use FileUpload Control and write code like
FileUpload1.PostedFile.SaveAs("Path and Filename");
You can easily use asp.net fileupload control: Uploading files in asp.net using C#
You can use ASP.NET file upload control which will handle this.You can mention where in your server you want to store it
