File.OpenRead() Accesses File On Share Within Workgroup But Not A Remote Share?
Mar 4, 2011
I have an ASP.NET MVC application that attempts to read a file in using a filestream and File.OpenRead().
When the path to the file is a share on the same workgroup, and I give access to NETWORK SERVICE for the share, this works perfectly as desired.
However, when the path to the share is a UNC path to a remote share within the LAN, with read permissions open for "Everyone", the "File.OpenRead()" method throws an exception saying "Could not find a part of the path".
In my test cases I'm debugging locally with the ASP.NET MVC app being given a UNC path to the computer that it's actually running on. It's a share on my C drive, being "Shared" with permissions to "Everyone" for read access.
Is there something in IIS that needs to be configured? If I try to impersonate, in this context, the impersonation doesn't matter because NETWORK SERVICE was the user trying to access the files when it worked for a share in the same workgroup.
I am showing thumbnail images in dataList on a page of my website. When i click on any image they open in big size. How i will share(Facebook). that particular big size image. My code is given below:
<script type="text/javascript"> var CurrentPage = 1; function GetImageIndex(obj) { while (obj.parentNode.tagName != "TD") obj = obj.parentNode; var td = obj.parentNode;
We have a web farm and are writing temp files for reports. We set up a file share and are using impersonation to write the temporary report files to that share. We gave the account doing the impersonation full control to the share and the folder itself.The files are writing correctly but are not being deleted.Is there something we're missing with this setup?
We have a legacy app with multiple asp.net themes. Each theme have a .skin file. Each skin file is almost identical except for some things. The files share a lot of similarities. Is it possible to share a common .skin file across themes?
I want to upload files to the web servers from the client machines.
Can i upload a file on a network share folder using file upload control?
I would like to create a share folder on a file server sitting next to the web server. If i upload the file from the network share folder instead of uploading it from the client machine does it make any difference?
Will the file be stored in a temporary location before copying to the final destination? Where will be the file stored in this case of uploading it from share folder?
I need to iterate through a server share and list every file within every folder and write each file name with all of its attributes into a database table.I assume that using the FileInfo class and all of it's properties (CreationTime, DirectoryName etc etc) is the best way but I have no idea of how to start.I'm starting to create a web app
how can I share one or two aspx file in two separated solution that if i change aspx file in both solution apply changes. Is it possible in visual studio 2008 or in Team foundation server?
I have to save a fileshare link in a sharepoint list and i want that file to be opened when the link is clicked, the normal sharepoint hyperlink column does not work for me in this case as it embeds the http:// with the url. How can I handle this scenario? the link i want to save is in the format 192.168.1.2myservermyfile.pdf and the text to be shown in the column is "myfile"
I'm not able to open the file when I click on the link on page in MVC. I get the following message. I've added the impersonation in the code. I'm able to delete and save the file.
Access to the path '\servernamefolder1folder2folder3foder4filename.pdf' is denied. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
I am trying to open a file share link from the window.open ... but its adding the http://localhost/vdir/ before the path can any one say what is the problem?
Is there a reason Impersonation does not seem to work with a UNC path using File.OpenRead()? I'm utilizing codeproject's Impersonation utility: [URL] I have a user with rights to the share that I'm passing to OpenRead(). This is my code and it's not accessing the file:
try { bool canImp = imp.ImpersonateValidUser(impUser, domain, impPwd); FileStream fs = File.OpenRead(filePath); logger.Debug("File stream opened..."); byte[] b = new byte[fs.Length]; fs.Read(b, 0, b.Length); fs.Close(); //code continued
I have an ASP.net 2.0 website that sits on a Windows XP SP3 box on IIS 5.1. The website needs to go across a UNC path to another server to grab an image file. Both boxes are in the same workgroup but no domain is setup. I have created the same user on both boxes with the same password and the website is using anonymous access using that account. The account is an admin on both boxes(i know security risk but this is for testing). File.Exists() just keeps returning false but the file is there. I suspect it has something to do with the ASPNET account but i'm at a loss. I've tried aspnet impersonation using that account as well with no luck.
I'm trying to force a large (200+ MB) file to download that's on a remote server. The problem is that I can't use the "WriteFile()" function, since I'm not using a virtual path. Then, when I try:
I am using the code below which I have found on one of the forums to download a file in remote server. it seems it is working. However, the downloaded file is corrupted and I cannot unzip.
After upload a pdf file (order.pdf) to remote server in UNC format, I used code below to open order.pdf file.Code is working in IE9 but not Chrome.Is there another way to open pdf file in remote server?
Dim fullpath As String = [String].Format("file:///{0}", "webserverorderorder.pdf") Response.Redirect(fullpath)
I have a library that is meant to be used by many websites. The way I am doing it now is in the library's properties, I set the "Post-build event command line" to: copy "$(TargetPath)" "$(SolutionDir)MyWebsitein$(TargetFileName)"
Every time I want a new website to use the shared library, I add a new line like this: copy "$(TargetPath)" "$(SolutionDir)MyWebsite2in$(TargetFileName)"
Is there an easy or better way to do this besides using the GAC?
The user accesses a web page (asp.net web application), makes his selections and applies filters to render the screen. Now I'm looking for a way to share this view with somebody else who also has access to the application.
Although in a simple scenario this can achieved through query strings and sharing the URL, how can this be achieved in a more complicated scenario where a bunch of selections / filters are applied to render a view ?
To start with, I implemented a basic framework. A datastructure will hold key value pairs which represents the controls and the values associated with it. I persist this to a database and the page will be responsible to parse the key-value collection and render itself but I think this may not be practical when there are complex controls like a grid with features such as grouping, filtering etc.
Most importantly, it would be great if the solution does'nt force the aspx to be implemented in a certain way for them to be persisted.

My company took some old php application over. Due to our preference to ASP.net and to the lack of any documentation from the previous developer, we do not want to spend much resources on developing in PHP. For implementing new features, we will create an Asp.net application that has the same look to the user. We want to develop a kind of 'coexisting' web application. Therefore we must share sessions between an PHP and an Asp.net webapplication project, because there is a usermanagement involved with an existing MySQL database.
(e.g. link 'A' directs to the PHP website, and link 'B' directs to the asp.net application)
How can we share the session between and PHP and an asp.net application?
And does anyone have a hint for this 'coexisting' thing, that might be useful in development?
There is a website with a master-page, set of css-files,... menus. It is necessary to implement another one that will have same (or at least very similar) look-and-feel. And also it is necessary to have look-and-feel in sync.
I've tried to find for appropriate solution (at least idea, not implementation) in the internet but didn't find anything.
use an additional project (class library) that will contain an implementation of the master-page and all its comnponents (menus, images, css, etc will be stored as resources), this project will be refferenced from all web-sites that need to sare look-and-feel.
Im using asp.net website with WCF service, having wsHttpBinding,Aspnet compatibility enabled, specified as Sessionmode -allowed, service behavior- isinitiated and client session cookie enabled. Its looking like Asp.Net session object and WCF Session( HTTPContext.Current.Session) work independently. How can I share Asp.net Session value to WCF Session and vise versa.
In the main thread I open a new thread that gets the number of new messages of user (takes about 5 secs) and this second thread should save the number in some place.
In the main thread I should check the "some place" and if the value exists I display it on the page.
Where can I save the value from the second thread to read it from the main one? This value is unique per user so I can't use static field.
