I have two web application hosted on different server.For eg. one is main application and the other one is branch application.
In branch application, user will upload their files but we want to keep all uploaded files in main application virtual directory.
So that we put the main application virtual directory path while we upload the files.But We got error message like "Invalid Directory" and can't upload.
Is there any way to upload files from one application to another directly? We are using normal html upload control in asp.net and visual studio 2008.
Code Sample :
main application virtual directory "http://10.10.10.1/mainapp/uploadedfiles/"
branch application virtual directory "http://10.10.10.2/branchapp/"
HttpPostedFile postedFile;
string saveFile = Path.Combine("http://10.10.10.1/mainapp/uploadedfiles/", "File1.pdf");
postedFile.SaveAs(saveFile);
Please guide me the right way and I really appreciated it.
Thanks.

In the FileUpload control, the FileUpload.SaveAs(path) method takes a physical path, not a virtual path. So if you have a virtual path, you will need to use the Server.MapPath method to convert it to a physical path. Using your example, you might want to change the last line of your code to:
postedFile.SaveAs(Server.MapPath(saveFile))
Also, you will need to make sure that the account that ASP.Net is running under has ACL write permissions on the physical directory.
I think u can share the directory and ensure both the Apps can access it, because the two apps are in different servers, the directory path maybe just like : \serverA\Files\, and the url of this directory is : http://localhost/files. u can save files to other servers by a relative path if u have the permission.

I'm trying to open folder location from code behind
Process prc = new Process();
prc.StartInfo.UseShellExecute = true;
prc.StartInfo.FileName = #"\\Shared\FolderName\test";
prc.Start();
After that I got it I couldn't achieve by using Shell32 class or Process.Start on server side as well as adding link to path cant be used because of the security problem so how can achieve this problem ?
Thanks for your help
That's right, you won't be able to launch an external process in a web application (and with good reason!). I think you need to reconsider what it is you're trying to achieve... perhaps some more information will help us give you a better solution?
A web application hosted on server can not access external file and folders on the system. This is due to security reasons. However if you want to access some specific folder, you need to create virtual directory and give path to that folder to the virtual directory. Now you can access that folder using virtual directory.
I worked on such scenario where I needed to upload file using one application (admin app) and needed to show on an other application (client app). So it works fine if you want to access outside resources.
I have a web application with a page. The page has a functionality to upload a file.
I have deployed the application on two different servers in IIS7. Both these hosting have a virtual directory pointing to the same physical directory.
Here I am unable to save the posted file in the virtual directory using Server.MapPath.
Is there any sophisticated technique to handle such situation to achieve this functionality?
Well I'd suggest you 2 scenarios:
Share a folder/resource beetween those servers (assuming that
those servers are in the same LAN), then create app key in the
web.config and this key will contain the path of your shared
resource something like //Server/Folder, use this value instead of server.mappath at the time you
save the file in the server
If you have a load balancer share a folder of your main node and
then use the that path in your secondary node something like
//server/folder that route will save the image in the main node, then
set up a replication rule from your main node and the secondary the
configuration of this rule could vary depending on your needs it
could be an update to the seconday node every 5 minutes for example.
you may create a virtual directory but the purpose for this will be only for displaying the images.
that worked for for me some time ago, it's not a fancy solution but it does the job.
I'm trying to read a file in a virtual path, using the following code
HostingEnvironment.VirtualPathProvider.FileExists(_SiteMapFileName)
_SiteMapFileName has something like "~/Content/en-US/MainMenu.sitemap" and it is always returning false.
But if I access the URL of that virtual path (http://www.local.mysite.com/Content/en-US/MainMenu.sitemap), the file displays correctly in the browser
Content is a virtual directory under my website, pointing to a shared folder on a different location. If I access that location on Windows Explorer I can see the files correctly
I've set the site and the virtual directory to connect as my network account.
I used the process monitor tool to see if there's any problem and it says that w3wp.exe is trying to create the file \path\to\shared\location\Content\en-US\MainMenu.sitemap but it is getting ACCESS DENIED which is fine since it is a read-only location
Does anybody now how to solve this issue?
I found out the reason. The user set to run the app pool tied to the application needs to have permissions on the file is trying to read, not only the website and the virtual directory. :/
when i am working with vDir i use Server.MapPath
Does that not work for you?
if(System.IO.File.Exists(Server.MapPath("Relative Path to vDir")))
{
//do something with the file
}
how can we find the path of browser default downloads folder in c# / asp.net?
For example I can get the path of user desktop like :
Environment.GetFolderPath(Environment.SpecialFolder.Desktop)
Thanks..
You can't find that out in a web application. It's up to the user to decide which browser to use and how to configure it and where to save downloaded files by default and you have absolutely no way of interfering or even knowing his choices from a web application.
First of all looking at MSDN on Environment.SpecialFolder there is no download folder, and the reason is that this is different for every browser.
http://msdn.microsoft.com/en-us/library/system.environment.specialfolder.aspx
And there have nothing to do with asp.net, if you look it from the server side you just get a directory on nowhere, meaning that this have nothing to do with the web application that run under the pool.
What you can do
You can use the HttpRuntime.AppDomainAppPath and use it to know where your site lives, and there place a "download" directory and use this full path:
HttpRuntime.AppDomainAppPath + "download/"
for download/upload files.
Noobie question...
Using IIS7, I am trying to create a virtual directory for the folder that contains my video files, but can't get my head around how it is done.
For example...
The existing address is http://www.mydomain.com/members
which points to C:\wwwroot\mydomain\members
I need http://www.mydomain.com/flash-members to point to the same path.
The existing IIS path to the members folder is Server\Sites\www_mydomain_com\members (has application icon)
Any help is appreciated.
For your example, assuming www_mydomain_com is the Site (little world icon), you can do this by:
Open IIS Manager
Right-click the web site, select Add Virtual Directory
In the Alias field, enter flash-members
In the Physical Path field, enter your path (C:\wwwroot\mydomain\members)
