If I have a web application that needs to use a file, it presents the user with a standard open file dialog. But instead of uploading the file to server can it modify the file locally in a temporary location, while uploading in the background? That way the user does not have to wait for the upload before they can use my web app.
View 1 RepliesIs it possible for an ASP.NET web application installed on a web server to connect to an Access database stored on a local PC (which is NOT the web server)? I would like the web application to allow the user to specify the path/complete file specification to the database. Or, based on login information specified by the user, the web application might determine the path to the database via an administrative database stored on the web server. The user/customer would be responsible for the storage of the Access database. If the answer to my first question is "YES", how do I programmatically specify/format the path to the Access database on the local PC so the web application can locate the database?
The path has to be something more than "C:foldernamesubfoldernamedatabase.mdb". When I use a path like this, the web application produces an error indicating that the database does not exist or cannot be found. So, I'm fairly sure that the web application is not starting with Drive C: on the local PC to find the database. For all I know, the web application may be interpreting Drive C: as Drive C: on the web server. I'm wondering if I need to specify a computer name before "C:" in the database path.
I have an ASP.NET page that I need to have access the local file system. It's an intranet. I need to download a zip file and an executable to a temp location and then run the executable.
Then afterwards, I need to delete the contents via an ASP.NET page.
Is there any way to access the local file system? Generally, I would think this would cause a security concern, but I've seen posts about Silverlight being able to access it.
My application creates some images at client machine using client side scripting VBScript. I want to store those images in database, so I need some way to bring those images to server without any interaction with users (means I can not use the file upload control).Along with this, application would also like to use the printer attached to client's machine (it could be her network printer), without showing printer dialog.
Basically I need to create some client piece, dll which will handle the scanning, printing and uploading images from client pc to server and web application will interact with this dll.How could I achieve this? I explored a lot on internet. many articles suggest that use activex control, but how in c#?
I am not asking any spoonfeeding. Please show me correct article or small working sample or example, I would figure out the rest.
I m trying to read the tags of a local HTML file. I found out this code online but it works for the aspx pages on the server and of the current app only.
___________________________________________________
using System.Web.UI.HtmlControls;
foreach (Control c in this.Page.Header.Controls)
{
if (c.GetType() == typeof(HtmlMeta))[code]...
THis code acceses the following section of an html page -
<meta name="Keywords"content=" B=Msdn;A=Forums;L=en-US;"
/>
My question is how can i do the same for a local(client) html page?
Can i do it for a html page on server?
I want to Access remote server( ie., want to access online server not local server) in my Application.. I change Settings in SQL surface Area Configuration---> Remote Connection ( checked the Local and Remote Connection ) Then while running the application it showing the following error.(I make off the firewall also) An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
View 1 RepliesI created a website using VS2010. When I run the website using built-in web server, everything works fine. The website recognizes javascript and aurigma uploader. When I publish the website to local folder and tried to access using IIS 5.1 on local pc,
the java scipt files did not work. I was getting yellow triangle sign at the bottom of the page indicating the object is expected. I tried to look online but i could not find any answer. I have included jquery and javascript file in the header section of master

I am using VSTS 2008 + C# + .Net 3.5 + Silverlight 3.0 + ASP.Net to develop a Silverlight application (a video media player) in browser and the function is simple, just use MediaElement to play a remote video file.The remote server is Windows Server 2008 + IIS 7.0 + IIS Media Bit Rate Throttling Control.Since the request media URL can be discovered (e.g. from traffic sniffer), and I want to know how to prevent from download directly from the Url? i.e. I want end user to use my Silverlight media player application in browser to play the file, prevent them from download to local directly. Any easy and quick solution or reference code/documents?
View 5 RepliesThere is a hyperlink to a local file...for instance....C:/text.txt. This is not possible, because ASP.net does not allow links to local files. But, links to files on network drives such as W:/test.txt are working ok. how does the browser know which drive letter is local,and which is networked? How does it know that C: is local or D: is local etc, and that W: is a network drive?
View 1 RepliesI want to write text file on remote location using .NET application. So can anyone tell me how to do this.

View 5 RepliesMy ASP.NET application logs transactions (both inside AND outside of databases), and therefore needs read/write access to text files within various directories within the root of the website - in ADDITION to the normal database access.
In this scenario, how can I safely allow my ASP.NET application to write data to the web folders? I have a thread-safe DLL that performs the actual work, so I don't believe I need to worry about multiple sessions writing to the log files at the exact same time - assuming my DLL will only be running in a single instance/process that will be shared between numerous ASP.NET instances/processes/threads.
But I'm more concerned about file access permissions. I've heard that ASP.NET applications generally aren't allowed access to the webserver's local file system, and that this may even restrict my DLL from getting the correct file access. Can I grant my application file-access to the web-driectories?
I am going to design system that will keep track of publications due by researchers in my work place
Need for this project :
1- a database housing the information .
2- Automatic reports must be generated .
the users will upload PDF and we have around 25 researchers.
I can't decide which one is better for my system .
My questions are :
1- Local web application or windows application ?
2- Access or SQL as database ?
3- I have visual studio 2010 for student use, Could I use it or I need to buy one ?
In our application, we allow user to upload documents which can be PDF, Doc, XLS, TXT. Uploaded documents will be saved on web server. We need to display link for each document user uploaded and when user click on that link, it should open relevant document. it is expected to have required software to open relevant documents.
To upload document, we use saveAs method of FileUpload control and it works absolutely fine.Now, how to view it?I believe, i need to copy/download file to local user machine and need to open it using Process.Start.For that i need to find user local temp directory. if i put path.GetTempPath(), it gives me web server directory and copy file there.
File.Copy(
sPath + dataReader["url"].ToString(),
Path.GetTempPath() + dataReader["url"].ToString(),
true);
it should be in asp.net. but, it is urgent and important, wish someone here know the answer.
what I need do for an asp.net page is:
1) client select a file, or;
2) client select a folder;
Get file (or files in the folder)'s properties, something like name, ext, etc. and save to db.
it will be easy if it is a desktop app. however, in asp.net, how can I do that? do I have to upload all files to server first? is there a way to do this for all files in a folder? any third party control?
I have an ASP.NET web application that runs on a windows server 2003 server. there is a form that reads and writes data to an xml file inside the application's directory.
I always grant the NETWORK SERVICE user full control on my application folder so that it can read and write to the xml file. I put the application on another windows server 2003 server and did the same steps above but i was getting an Access denied exception on the form that reads and writes to the xml.
I did some search and found that if you grant the user ASPNET full control to the directory it would work, I did that and it worked fine. my question is: what is the difference between granting full control permissions to NETWORK SERVICE and ASPNET users ? and what can be the difference between the two servers that caused this issue ?
Is it possible to configure web.config to authorize a page to be only read locally (similar in concept to the RemoteOnly feature for error messages).

I'm new in the WCF and in the web developing ..
I wrote WCF service and i by creating new Web Sites - i added new WCF service that will host my WCF service.
In the 'Web location' i define the service to be HTTP and the URL to be "http://localhost/MyService"
Now i want to access thru some other machine ( in the same network ) to my machine and get using the Service method that my WCF service exposed - but i fail each time ( calling from the second machine "http://a.b.c.d/MyService/interfaceMethodName")
If i try to call the web service thru the same machine - i get the right response.
I have done an application in my PC i would like to access it on other pc how can i do this.
View 4 Repliesthis might not be asp.net exactly but i hope it's ok that i ask this here?i'm looking to restrict access in web browsers to a particular extension like .mp3 - really i'd like to know how to do it two ways if possible
1: how can i restrict it so that nobody may embed/play/download mp3's on my server on their outside sites? I used to do this on php with .htaccesss but am new to .net2: how can i completely revoke the extensions' ability to function at all, even on my site? IE: I would test with a link on my own site/server to a mp3 on that server, and it would fail. I tried removing the MIME type for mp3 and restarting IIS but thatdoesn't seem to have done it.I can still go to the mp3 file in my browser by putting it's URL in the browser.

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 wanted to run a .net application on a laptop. I created the application(aspx pages and SQL database) on a computer that has VS 08 installed. Now i wanted to run this application on a laptop that does not have SQL sever 2005 installed.
As far as the aspx pages if i publish them to a zip drive copy it to my laptop and go into IIS and define a new virtual directory to point where my pages are that should work RIGHT??
Now for the database i don't know what i need to do
