I am using this code for creating pdf viewer in my application
https://amitpatriwala.wordpress.com/2009/08/28/pdf-viewer-in-asp-net/
it works fine when I give it a path for a file inside my application folders, ex: displaypdf1.FilePath= #"~/MyFolder/" + Hello.pdf;
but now I want to give this displaypdf1.FilePath an absolute path to read the pdf file which is not in my application folders, I tried but it didn't work!
A web page cannot access items that are outside of the website. If you want the web page to reference files located in D:\PDFs, for example, you need to create a virtual directory in your website that points to "D:\PDFs". Then the web pages can access them by ~/PDFs/Hello.pdf.
You'll also need to ensure that the website has appropriate permissions to access the directory.

I have the following structure:
AppName
Content
img
file.png
I can navigate directly to mysite.com/Content/img/file.png without any issues.
However when I add test.txt to img and set to Copy Always and type Content (same as file.png), I get No webpage was found for the web address when visiting the link, when I want to be able to enable folks to download the publicly accessible file (no auth needed), just like the image. Why isn't this working?
I can see test.txt in the bin folder of the app. Does something else need to be configured to enable direct file downloads?
Make sure your IIS site settings or web.config have mime type associated with .txt extension.

I am trying to create a Sharepoint webpart for a user to browse to, and select, a file from a share on our file server. Then I need to create a link to this file to display in a list of links that will go onto our Sharepoint intranet page. I have created a custom web part using asp.net/c# in order to do this but I am stuck on how to get the UNC path to the document. From my understanding it wont work with an asp.net fileupload control or a html input element. What other options would there be? I really don't want the user to have to type in the whole path to the document. This needs to be a re-usable solution so that my users can create new lists of links to documents when they so desire. Thanks for any advice.
I don't think the full file path is supported or allowed via modern web browsers via the file upload control. What you would end up having to do is create something server-side that use a service account to access the file share, and then the client (web page) could call the server-side code as it traverses the file share until the user selects a file.
Example:
server: on load, here are the contents of "\server\home"
client: show the contents of subfolder "\server\home\pictures"
server: connects to "\server\home\pictures" and returns contents
client: selects "\server\home\pictures\foo.jpg"
Check out System.IO.Directory http://msdn.microsoft.com/en-us/library/system.io.directory(v=vs.100).aspx for ways to get listing of directory contents server-side (GetFiles, GetDirectories, GetFileSystemEntries, etc) and then you can return those results to the client.
I have set of files (which are essentially ".exe" files) that I allow the users to download from my website. To have a clearer picture have a look at the this screenshot (it is just a academic project). Now I have administrator privilege in which I can upload a new software file to a folder (componentsFolder) to the root of my website and I also add the filepath to the database table at the same time.
I'm using the following code to do that:
string componentRelativeFilePath = #"/ComponentsFolder/" + ComponentName;
I'm storing the filepath in the following format in the database file:
/ComponentsFolder/FileName.exe
What is the difference between storing the files in the following formats?
/ComponentsFolder/FileName.exe
\ComponentsFolder\FileName.exe
~/ComponentsFolder/FileName.exe
~\ComponentsFolder\FileName.exe
I'm using server.mappath to retrieve the file from the root folder.
I want to know the difference (in this context) between these formats and which one is the standard/appropriate/technically correct format to store the relative paths in database table.
In terms of Asp.Net lets suppose you set your image path as "/Image/pic1.jpeg" so the image would be searched in Image folder located in website root and in that folder pic1.jpeg is searched. If your set you image source to "~/Image/pic1.jpeg" in that case as well the image file is read from the Image folder that is located directly under the root of the Web application, regardless of where in the Web site the page is located. But '~/' this could only be used with server controls.
If path is "../Image/pic1.jpeg", in that case Image folder is searched in the current webpage's folder.
As per my opinion storing path in "~/Image/" format is a better choice in terms of Asp.Net.
Hope I answer your question.
I need to display an Image in web page. But the Image doesn't exist in the Web directory. If the image is under web directory I know that just "../Images/TN/my.jpg" will work. But the image is available in "D:\Images\TN\my.jpg" and My web site is deployed in "C:\apps\mywebsite".
How do I convert the "D:\Images\TN\my.jpg" path to a relative path so that the Image will be visible in web page?
You cant show images if they are not in a virtual directory.
Try holding then in your application folder itself or if its not feasible then make your Folder holding the image as a virtual directory in the IIS and mount it in your application folder.
Here's what you need to do (way i prefer),
Open IIS manager.
In Connections under Sites Select your Website and RightClick on it.
Select `Add Virtual Directory`... from the Context menu.
In The dialogue box that opens Enter the Alias name of your choice like **`"GlobalImages"`**
Browse the physical path of the Folder you want to and Select it and Click OK.
You will have it available for relative url in that website. like
www.example.com/GlobalImages
When you set that in IIS, it is automatically added to your Solution's Project.

Easiest thing to do is probably set up a handler and use the generic image name. While local, point to the D:. While on the server, point to the web path. (At least so long as you're not keeping them within the virtual directory that is).
TO fetch this point, we always write the absolute directory for images or other resource.But if the resource in the web server, i use the relative directory.
I have a requirement where i want to load pdf document in a web page from a physical path. The pdf document location is not inside my website directory. To elaborate on this with example: Let assume my virtual directory refers to "c:\website". I have all my pdf documents stored under different folder called c:\pdfDocuments". On one of my web page i want to load my pdf document from c:\pdfdocuments. Is there way to pass the absolute path in this case (c:\pdfdocuments\x.pdf) to frame control's src attribute.
Thanks
CS
No, you cannot do that unless the C:\pdfdocuments is also a website; and in that case you would need to pass in the URL that relates to that physical path.
Keep in mind that the frame, or other html element, is trying to load the contents of the file accross the internet from the browser to your server. The browser on the clients end has no knowledge nor access to your physical filesystem, only what is exposed via the web server.
Now, if you're trying to load this on the server side, then you should be able to use the physical path as long as the worker process has access permissions to that path. But based on the question ".. to frame control's src attribute." I'm assuming you're referring the the client side html.
