i have an asp hyperlink i want to link it to a .doc file found on a shared folder.
i was able to do this in internet explorer but not in firefox:
my code:
hlc.NavigateUrl = #"file:\\direct\upload\file.doc";
Might want to use forwardslashes (as per convention)
hlc.NavigateUrl = #"file:///direct/upload/file.doc";

I am currently trying to create a web service application using Visual Studio 2022 ASP.NET Webforms application with a service reference. The goal is to take in information and store it as a text file on the local machine within the project folder so it is accessible by the web service on my local server.
I have successfully created the text files and can access them on my local machine, but when I navigate to the text file on my local server tree I get an HTTP Error 404.0 which is shown below. I need any user who accesses my server to be able to access the saved text files. I have tried to change security privileges on the folder and in my web.config file, but have not had any luck. I would appreciate any suggestions someone may have.
Here is my code for where I save the information as a text file.
// Randomly generate string for text file name
var chars = "abcdefghijklmnopqrstuvwxyz0123456789";
var textFile = new char[4];
var random = new Random();
for (int i = 0; i < textFile.Length; i++)
{
textFile[i] = chars[random.Next(chars.Length)];
}
eventFile = "\\";
eventFile += new String(textFile);
eventFile += ".txt";
folderPath = Server.MapPath("~/Events");
File.WriteAllText(folderPath + eventFile, fullEventDetails);
Both my URL and local file path are the following:
URL https://localhost:44399/sx1l.txt
Path Name \\Mac\Home\Desktop\Homework3\Homework3\sx1l.txt
Ok, so you have to keep in mind how file mapping works with IIS.
Your code behind:
that is plane jane .net code. For the most part, any code, any file operations using full qualified windows path names. It like writing desktop software. For the most part, that means code behind can grab/use/look at any file on your computer.
However, in practice when you use a full blown web server running ISS (which you not really doing during development with VS and IIS express)? Often, for reasons of security, then ONLY files in the wwwroot folder is given permissions to the web server.
However, you working on your development computer - you are in a effect a super user, and you (and more important) your code thus as a result can read/write and grab and use ANY file on your computer.
So, keep above VERY clear in your mind:
Code behind = plane jane windows file operations.
Then we have requests from the web side of things (from a web page, or a URL you type into the web browser.
In that case, files are ONLY EVER mapped to the root of your project, and then sub folders.
So, you could up-load a file, and then with code behind save the file to ANY location on your computer.
However, web based file (urls) are ONLY ever mapped though the web site.
So, in effect, you have to consider your VS web project the root folder. And if you published to a real web server, that would be the case.
So, if you have the project folder, you can add a sub folder to that project.
Say, we add a folder called UpLoadFiles. (and make sure you use VS to add that folder). So we right click on the project and choose add->
So, you right click on the base project and add, like this:
So, that will simple create a sub folder in your project, you see it like this:
So, the folder MUST be in the root, or at the very least start in the root or base folder your project is.
So, for above, then with UpLoadFiles, then any WEB based path name (url) will be this:
https://localhost:44399/UpLoadFiles/sx1l.txt
(assuming we put the file in folder UpLoadFiles).
But, if you want to write code to touch/use/read/save and work with that file?
You need to translate the above url into that plane jane windows path name. (for ANY code behind).
So, if I want to in code read that file name?
Then I would use Server.MapPath() to translate this url.
say somthing like this:
string strFileName = "sx1l.txt";
string strFolderName = "UpLoadFiles"
string strInternaleFileName = server.MapPath(#"~/" + strFolderNme + #"/" + sx1l.txt";
// ok, so now we have the plane jane windows file name. It will resolve to something like say this:
C:\Users\AlbertKallal\source\repos\MyCalendar\UpLoadFiles\sx1l.txt
I mean I don't really care, but that web server code could be running on some server and that path name could be even more ugly then above - but me the developer don't care.
but, from a web browser and web server point of view (URL), then above would look like this:
https://localhost:44392/UpLoadFiles/sx1l.txt
And in markup, I could drop in say a hyper link such as:
UpLoadFiles/sx1l.txt
So, keep CRYSTAL clear in your mind with working with path names.
Web based URL, or markup = relative path name, ONLY root or sub folders allowed
code behind: ALWAYS will use a plane jane full windows standard file and path.
But, what about the case where you have big huge network attached storage computer - say will a boatload of PDF safety documents, or a catalog of part pictures?
Well, then you can adopt and use what we call a "virtual" folder. They are pain to setup in IIS express, but REALLY easy to setup if you using IIS to setup and run the final server where you going to publish the site to.
Suffice to say, a virtual folder allows you to map a EXTERNAL folder into the root path name of your side.
So, you might have say a big server with a large number of PDF docuemnts,
say on
\\corporate-server1\PDF\Documents
so, in IIS, you can add the above path name, say as a folder called PDF.
Say like this:
So, WHEN you do the above, then the folder will appear like any plane jane folder in the root of the project, but the file paths can and will be on a complete different location OUTSIDE of the wwwroot folder for the web site.
So, now that we have the above all clear?
\\Mac\Home\Desktop\Homework3\Homework3\sx1l.txt
But, your code has this:
folderPath = Server.MapPath("~/Events");
File.WriteAllText(folderPath + eventFile, fullEventDetails);
(you missing the trailing "/" in above, you need this:
File.WriteAllText(folderPath + #"/" + eventFile, fullEventDetails);
So, that means the url for the text file will then be:
https://localhost:44399/Events/sx1l.txt
And if you using Visual Studio to add files to that folder (add->existing items), then MAKE SURE you Build->rebuild all (else the file will not be included in the debug run + launching of IIS express.
So, given that you saving into a folder called Events (as sub folder of wwwroot, or your base folder for hte web site, then the above is the url you should use, but your code always was missing that "/" between folder and file name.
I am looking for a way to derive the OneDrive file URL for a file cached to my local OneDrive folder? The only thing I can think of is hardcoding some root URLS for each of the OneDrive folders I have, but this seems nasty!
Does anyone know of any OneDrive client API that lets query a URL based on the local file path?
My use case:
I am trying to attach to and open instance of an Excel workbook. I used to be able to do this Marshal.BindToMoniker(_workbookPath);
However it appears that Excel is now registering the OneDrive URL in the ROT rather than the local file path. This this happened with the update that brought the new auto-save feature to Excel 2016 I think, that seems to be about the time my existing code broke.
There is a similar unanswered question here: C# OneDrive for Business / SharePoint: get server path from locally synced file
Might want to use the following key instead:
HKEY_CURRENT_USER\Software\SyncEngines\Providers\OneDrive
This includes the following registry values:
UrlNamespace: (SharePoint site URL)
MountPoint: (local driver location)
It does appear to include old values which are no longer synced - but it shouldn't be too hard to check against
HKEY_CURRENT_USER\Software\Microsoft\OneDrive\Accounts\Business1\ScopeIdToMountPointPathCache
or
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\SyncRootManager
for paths that are being actively synced.
I am also looking at a solution for getting the SharePoint url to a file in OneDrive Synced File Explorer.
I have noticed you get under C:\Users%username%\AppData\Local\Microsoft\OneDrive\settings\Business1{GUID}.ini a mapping between your OneDrive synced folder and the SharePoint GUID
Example:
libraryScope = 1 630c2a866d9c458b81060eff107887ed+1 5 "GUIDEs" "Documents" 4 "https://mytenant.sharepoint.com/teams/team_10000035" "8d4b558f-7b2e-40ba-ad1f-e04d79e6265a" e0266a43caf347238f684bab486f4e51 e0d25dcb1a014f5f86d787984f6327c2 4f86b3e3e54e42e0bb0f7a58eadf0335 0 "" 0 4cde5c00-3fe3-4162-b831-d8ef440e1593 libraryFolder = 0 1 8bbfe07dfeff41cea7ab5da4a554592a+1 1558084235 "D:\DSUsers\uid41890\TenantName\GUIDEs - General" 2 "General" bd0c1b7c-2a1f-4492-8b1b-8e152c9e0c26
You also have this mapping in the registry Computer\HKEY_CURRENT_USER\Software\Microsoft\OneDrive\Accounts\Business1\ScopeIdToMountPointPathCache
From the GUID you could get the path using SPWeb.GetFile(Guid)
If you can make a standalone function given a local OneDrive file path that returns the SharePoint url, I would greatly appreciate you share your solution here.
I have implemented a solution in AutoHotkey see documentation here
It is based on #GWD idea (see comments below) to generate a temporary excel file with the formula CELL("filename") at each sync locations to extract this mapping information to a text file that is then later parsed to do the reverse mapping from local file to SharePoint url.
Trying to automate file downloads, using Watin in IE. Have a 10 documents to be downloaded and i could find that the below code will prompt for download option.
string download_url="link to file";
browser.Goto(download_url);
I would like to automatically save these files into a new directory with custom names for each files. Is it possible without user prompt for saving files in IE(vesrion 8 and above). Please guide me with a solution for this issue.
From your question I can find several other responses right here. Like this one:
Downloading a file with Watin in IE9
using(IE ie = new IE(someUrlToGoTo))
{
FileDownloadHandler fileDownloadHandler = new FileDownloadHandler(fullFileName);
ie.AddDialogHandler(fileDownloadHandler);
ie.Link("startDownloadLinkId").ClickNoWait();
fileDownloadHandler.WaitUntilFileDownloadDialogIsHandled(15);
fileDownloadHandler.WaitUntilDownloadCompleted(200);
}
I try to display html file inside an iframe.
The html file is located inside a local folder on my server, with the relevant permissions (for example: c:\temp).
I tried:
iframe = document.createElement("iframe");
iframe.src = "file:///c:\temp\a.html";
iframe.style.display = "block";
document.body.appendChild(iframe);
But the content is not displayed inside the iframe.
another solution I tried is to use ajax to display the html inside a div:
$("#DIV").html( *READ HTML TEXT FROM FILE *)
But the problem here is that I have pictures and css file included inside the html page, and they can't be displayed because the current location is my web site (they are included in c:\temp folder with the html).
Does anyone have an idea how can I display html page with images inside an iframe?
The problem is that the browser sees that file:///c:\temp\a.html as a file local to the browser, so it points to the C: drive of the visitor.
You can set up that local folder to be a Virtual Directory of your website (in IIS) and refer to the file using the correct web-path (http://...). That way you don't move the folder but it is still available through the webserver.
Assuming it works properly when you load the html file from the root instead of temp (thus, ruling out everything except an issue with the file location), you can load a file relative to your website as long as you have access. It does require understanding your path(s) - both local and server, if applicable. For instance, I have a folder called ‘temp’ on a hosted server that is a peer to my website.
Using Request.PhysicalApplicationPath, I find that my site is located here on my host: "c:\inetpub\wwwroot\mydomain.com\index.htm”. Therefore my temp folder & file must be at “c:\inetpub\wwwroot\temp\myfile.txt" (again, temp is a peer to my site).
Crude Example:
string _filePath, _uriServerName = "";
_filePath = Request.PhysicalApplicationPath;
_uriServerName = Request.ServerVariables["SERVER_NAME"].ToLower();
if (_uriServerName != "localhost")
{
int rootPos = _filePath.IndexOf("wwwroot"); //get position wwwroot
_filePath = _filePath.Substring(0, rootPos) + "temp\\myfile.txt";
}
I use the above for loading files outside web site. For that, it works well. However, an iframe may present some other challenges. I don't believe this should present any cross-domain issues, but I'm not perfectly sure.
I saved aspx page as html it worked in my local machine but after published on the server its showing an error that "the access to the path is denied"... I tried giving access permission then also it doesn't work.. can anyone help with it? or else is there any other way to save the page in C# asp.net?...
string url=HttpContext.Current.Request.Url.AbsoluteUri;
string sHtml="";
HttpWebRequest request;
HttpWebResponse response=null;
Stream stream=null;
request=HttpWebRequest)WebRequest.Create(url);
response=(HttpWebResponse)request.GetResponse();
stream=response.GetResponseStream();
StreamReader sr=new StreamReader(stream,System.Text.Encoding.Default);
sHtml=sr.ReadToEnd();
string path=Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
string textfilename=TextBox1.Text;
string getpath=path+"\\"+textfilename+".html";
File.WriteAllText(getpath,sHtml);
if(stream!=null)stream.Close();
if(response!=null)response.Close();
Thanks..
If you need to save a file use this to get the application path
Server.MapPath(#"filename.txt");
Try this because when you only write the filename at an web server you are trying to access to a Microsoft.Net folder.
yes make sure the folder you write to has the appropriate privileges. IIS 5 uses ASPNET account, IIS6 uses network service. Just give read/write to the proper account. Is this your dev environment, or a prod environment?
Also, make sure it's pointing to a folder; desktop folder for ASPNET account probably won't exist since ASPNET account isn't a user with a users folder.
I had a similar problem when trying to deploy CSS from a ZIP downloaded from the web. Try right-clicking on the aspx file from windows explorer and checking the file properties. One of the tabs may indicate that the file has been "blocked". If so, there will be a button there to unblock it.
