it may not have to do with silverlight as such, but a "security" issue. I appologize if that was wrong.
I´m having a go at silverlight...
I want to display large amount of data in good looking charts. Ideally, I would use a web service. However none of the tutorials I´ve watched works. There´s always some component or class missing.
So I figured I´d do it the "ugly" way, creating a xml file from a dataset, and then reading it in the silverlight app.
Now when debugging, I use a local file, which is apparently not permitted
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?
I am trying to read a text file from the root of the server. This is what I tried
Code: Dim sr As StreamReader Try sr = File.OpenText("~ est.txt") Label1.Text = sr.ReadToEnd Catch ex As Exception Label1.Text = ex.Message End Try
If I test this locally, I get the error: "Could not find a part of the path 'C:Program Files (x86)Common FilesMicrosoft SharedDevServer10.est.txt'."If I upload it and run the code on the server, nothing happens (Lable1.text does not change).
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.
I know this is probably a pretty easy thing to do and it is if I can upload the file and store it onto the hard drive of the server. What I need to do is read the text file into memory and then parse through it one line at a time. Anyone have any code that demonstrates that?
There 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?
I have been working with ASP.net for a while now and was very familiar with how the page lifecycle worked. I am now trying to incorporate Silverlight into my ASP.net project and I am a little confused on how it works with the ASP page lifecycle.
For example, with Silverlight, I understand you need to access the server using the web service. I am able to populate a Silverlight datagrid by calling a stored proc through the web service in the loaded event. My problem is the DataGrid does not populate until ALL the code in the loaded event has executed. As you can see below, I want to do a simple calculation after I populate the DataGrid. I need to populate the DataGrid first and then do the calculation, but the calculation is done before the grid populates.
What I need to happen:
When I call 'tpService.getStepsAsync()', I need it to go to the web service to grab the data and then populate the DataGrid. Then I need 'a = 2 + 2' to execute. How can I get this to occur?
Either I am blind with excitement or something is missing from VS2010. I have created a Silverlight 3 project and simply want to add a web reference (not service reference) to the project. I cannot see the 'Add Web Reference' anywhere.
I added it to the toolbar and it was disabled. I saw somewhere that I might need to change the target framework version but I cant see where to do that in the project properties either.
I would like ask you for some ideas how can I write mechanism that will be automatically read files from folder. I don't know how to schedule the write task. I want to check for new file everyday and if the new file is in the folder read it.
but when I tried to add the service reference to the silverlight app, the Add Service Reference window would show me that there was a service file, but the node wouldn't expand to show the rest of the files that contain the services and what not. I got this error instead:
"An error occurred during the processing of a configuration file required to service this request. review the specific error details below and modify your configuration file appropriately."
"Parser Error Message:There is no service behavior named 'AdventureWorks_WebServer.Service1Behavior'."
"Metadata contains a reference that cannot be resolved: 'http://localhost:55579/Service1.svc'.
The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.
If the service is defined in the current solution, try building the solution and adding the service reference again."
I have a Silverlight site hosted in an asp page, it has been developed using vs2010 using .net 3.5 framework and silverlight 4. It all works on my dev box. However when I publish the site and get it deployed I get the error:
Could not load file or assembly 'Moe.Tactical.Ttas.Web' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
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.
Exception Details: System.BadImageFormatException: Could not load file or assembly 'Moe.Tactical.Ttas.Web' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
I have checked that the ISS asp setting are using 2.0.50727, and that all my references are using that runtime also.
I am not sure what to do to work out what the missing dependencies are at this point (I don't have access to the deployment box, I will have to go and sit with a system admin).
I started working on an ASP.NET web app for my companies local intranet. While coding it, I emailed our IT team, to get an intranet domain/server setup.
So, they emailed me back with the server credentials+the domain. But, I'm not really sure what to do from here.
How I need to setup the server and ASP.NET settings to get everything working?
I've just downloaded VS2010 Express to play with on my personal laptop. However, when I try to open an existing website through the "Open Web Site..." / "Local IIS" button, the system trundles on for a bit and then says: "To access local IIS Web sites, you must install the following IIS components: In addition, you must run Visual Studio in teh context of an administrator account."
Note the blank line after the "you must install...." [strikeout]Is this a limitation of the "Express" editions of Visual Studio? [/strikeout] I've just installed VS2010 Premium from our MSDN DVD and it has the same problem.... Also, seems to have broken VS2008 as well since I can no longer browse Local IIS from VS 2008 either. Good thing I installed this on my backup machine first and I can still get work done on my main development machine!
I am doing an AJAX call back to a WebMethod but in the code behind webmethod I cannot use any of the constants at the to of my form. What I want is to gain access to sessions and my sql connection string.
I'm sort of new to developing Asp.net webapplication projects while running them on a local IIS. Till now I used the 'Use Visual Studio Development Server' option.
I'm using Visual Studio 2010 Beta 2.
Edit: less complex sample code
Following code sample:
List<string> _list = new List<string>(); _list.Add("asd"); _list.Add("asd2"); _list.Add("asd3");
Now I want to debug / step through some line of codes with _list. While using 'Use Visual Studio Development Server' I can see the contents of _list in the quick watch. If I select 'Use Local IIS Web server' and debug through the same piece of code, the quickwatch tries to display me the same values by showing me a spinning wheel for about 10 seconds with a resulting 'Function evalutation disabeld because a previous function evalution timed out. You must continue execution to reenable function evalution' message.
Afterwards I get a windows error dialog with 'Unhandeld win32 exception occured in w3wp.exe [844] The Just-In Time debugger was launched without necessary security permission..'
I do run Visual Studio 2010 Beta 2 as Administrator. I start debugging by pressing F5. It seems that I can't really debug this way. Do I somehow have to attach the VS debuggerto the IIS process? If yes, how to do so?
What am I doing wrong, and how to solve it?
And by the way, is that erroneous behaviour new in VS 2010? I've never expierencied that in VS 2008.
Why when I generate local resource does it check out the web.config. I've done a comparison after the process has completed and the web.config hasnt changed.I'm using TFS 2010 Basic.It's not a big issue but I would be interested if anyone knows the answer.
I would like to find a way to read a txt file (in my case delimited by ¤). I need to change the order of the columns and also add and remove some columns. My output file should be a txt file delmited by ;.
I tried Jet.OLEDB to read the file and put it into a datatable and then used a stringBuilder and streamwriter to get an output file in .txt format. However. This does not me since I´, reading the txt file from start to end and my output will be the same. It does not seem like I can have a custom sql statement when reading the file. The only query that works is
Dim da As New System.Data.OleDb.OleDbDataAdapter("Select * from 1.txt", TextConn)
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.
I'm new to ASP and was hoping to get some hands-on experience of web development, but have been having trouble getting started.
I followed the instructions in the [URL] setup video, and downloaded and ran the plaform installer. I noticed that the "Web Platform" section of the installer was didn't have the "Web Server" section at the top, as shown on the instruction video [URL] but it otherwise seemed to install ok.
When I tried to follow the tutorial videos on [URL] using MS Visual Web Developer 2010, I am unable to debug the application. The web page it loads just says: "The webpage "localhost:xxxxx" cannot be found" (where xxxxx is the five digit random port number).
I've tried uninstalling Visual Web Developer, and the various Microsoft .NET and SQL Server using the Vista uninstall functionality of the control panel (as bet as I could -I'm not sure if there was something I missed), and then re-installing, but I still get the same problem.
I've tried to find a solution on some developer forums, and I noticed there are posts relating to webdev.webserver.exe relating to the error message I've been getting. However I haven't been able to find any info on this for VS 2010.
I've checked, and I don't have webdev.webserver.exe in C:Program FilesCommon Filesmicrosoft sharedDevServer or in C:WindowsMicrosoft.NETFrameworkV2.0.50727, although I do have WebDev.WebServer20 and WebDev.WebServer40. inC:Program FilesCommon Filesmicrosoft sharedDevServer 10 (I'm not sure if one of these is the equivalent files for VS2010.)
I've also made Internet Explorer my default web browser, since some of the forum posts mention this. My firewall is on, but I don't get any error messages relating to the firewall when I run the app. However, I wasn't sure whether there was a particular program I should add to my "allowed" list before running.
I ran the diagnostic tool: [URL] and I get the following output:
THE FOLLOWING SCRIPT will check to make sure that .NET Framework 3.5 is installed properly and will tell you what is not configured appropriately WINDOWS VERSION: 6.0.6002 POTENTIAL ERROR: REGISTRYDUMP: reg query "HKLMSOFTWAREMicrosoftNET Framework SetupNDPv2.0.50727" /v "SP"
