Determine Which Css Media Type Is Being Requested On Page?
Oct 15, 2010
I'm looking to alter the way my asp .net webpage is output to the browser depending on the css media type being used. Although the css is generally taking care of the differences in appearance between screen and print mode I would also like to make some minor adjustments to the markup when print mode is required. I would simply be dropping a floated section down below its sibling rather than as a 2 col approach which is to used during screen layout in the browser.
In Visual Studio 2008 I have a Class Library project (called Media) to which I added a Web Reference (not a Service Reference) to a third-party web service (wsdl). In the Class Library project a proxy class is created for using the service along with several classes for the types used in that service.
I also have a second Class Library (called Sync) that references the first one. And then I have a Web Site project that references the second class library. All of this is .NET 3.5
So Web Site > Class Library (Sync) > Class Library with web service reference (Media)
I want to step into the generated code, so I fire up the web site in IIS 7.5 and trigger the call to a method in the second class library (Sync) that in turn should call the web service proxy. I was fully expecting to hit the breakpoint, but instead got an exception:
Unable to generate a temporary class(result=1). error CS0029: Cannotimplicitly convert type Media.WebService.multiValuedAttribute to Media.WebService.multiValuedAttribute[]
Why is ASP.NET trying to generate a temporary class? Don't I already have the generated class from the first Class Library (Media)?
I have a table in my SQL Server DB that holds auditing information for certain actions a user takes within my system. Things like who performed the action, when it was performed, and what action are all pieces of information that can easily span multiple actions. But depending on the action performed, there may be other information that I want to capture, that is specific to the action. To handle this, I elected to add an "XML Metadata" column to the table that holds serialized XML of different metadata objects that I've created. I created a metadata object for each of the actions that I'm interested in tracking extra for. So each object is responsible for tracking specific extra information (metadata) for it's action. The objects are serialized and written to my new column.
I have SystemAction objects that I use to store information from this table, and I've added a string field that holds the XML string from the DB. The problem is, when I'm reading this XML back from the SystemAction objects, I'm struggling with a way to generically translate it back into it's correct metadata object. Each metadata object is going to have different fields, and each object has it's own static method that takes an XML string and attempts to return the metadata object type. So I could say:
But I really don't know of a way to say "Here's some XML that could translate to any number of different objects. Figure it out and give me the right object back."
Given my current implementation, I could always just assign a unique ID to each metadata object that is stored as a field in each object, then use a case statement to switch on that ID and use the appropriate class's static build method to build the right object. But I was hoping for something a little more automatic than that. What if I have a List of SystemAction objects and just want to loop through them and generate the correct metadata object type?
I have a asp.net vb.net app, with a upload file control, when i upload the file i can get the type of file the extension : .(extension),But if the user change the extension how i can get the real type of file?
I want to determine the browser type in code-behine file using C# on ASP.NET page.If it is IE 6.0, I have to execute certail lines of code.Can anybody provide code sample.
I have an application that I would like to be able to allow the user to modify multiple characteristics of each record within a datagrid.
Most characteristics require data to be entered in a text box but some a check box would be more appropriate.
My question is does a gridview column need to have all the same item template controls? or could I read from the database the control type and dynamically alter the template control for each row as it loads?
I have created an order checkout page.when i click checkout button then it check user login or not if not then it redirect to login page .after login i want to show
I am trying to write a function that can be called to run a stored procedure. I pass the stored procedure name, followed by as many parameters as I need to run the procedure. I am able to do this by using the params keyword, so my function looks something like this;
[Code]....
How can I determine what the data type of the parameter is? Maybe I need to alter the string[] part, above?
I'm looking to pick brains on the following.I have a page which contains numerous links to other websites.I use a redirect to get to the destination page so I can run any code prior to the redirect. What I would like to do is attempt the redirect, but then display an error message if it doesn't happen in say 20 seconds.I already have code to check a link so I can check, then if available redirect, however I would prefer to redirect and catch an error.
I have an ASP .NET 2.0 (4.0 is an option) page that I've embedded the Windows Media Player to using OBJECT tags.
The player is connecting to a Windows Media Services publishing point on the Web server. This is on a 2008 server.
Everything works great, see it here: [URL]
If I understand correctly, the information the player is showing in its status bar comes from the ID3 tags of the current track. Continuing on this line of thought, the ID3 information must be coming to the player from the media server. Correct?
What I want to do is collect and use the information about the track that's current being played. I'd like to be able to create a custom display for the current track information. I'd also like to put a custom value in the track information to look up additional information about the artist/track from a database.
I have an ASP.NET web application where a Microsoft Media Player object on the page (in IE) is issuing a request for an .aspx web page. In the page I use TransmitFile to send back the audio file. This works fine most of the time.
But, in some cases (a combination of IE version and a specific client, at least from what I can see) there is a second request issued, with the exact same URL. The only difference I can see between the first and second request is the user-agent value. The first request will have User-Agent: Windows-Media-Player/9.00.00.4508 and the second one will have User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)
This second request is causing the audio file to be sent a second time over the net, which is wasteful. This is what I'm trying to avoid. I had a related question here, but in this case there is no Range request. It is just the same exact request again (same headers, except for the user-agent).
I was trying to suppress the second response (based on the user-agent in the header) with all kind of HTTP status responses (304, 404, 500 etc.) This works for some clients, some of the time, but breaks occasionally (the Media Player will just not play the audio, even though Fiddler will show it was transfered on the first request).
I would like to "convince" the browser to avoid the second request, if possible. As a second option I would like to find a response to the second request that will not break the playback, but avoid sending the whole audio buffer.
In my asp.net and vb code web. there is some pages which require username and password to access it. when the user clicks on the link for this page it directs to the login page and if the username and password is correct then it is directed to default page and not to the page requested.
Code in my .vb page is as under
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Session("userid") = Nothing Then Response.Redirect("login.aspx") End If End Sub
i have the following bit of code... is there a way to embed a media player into a webpage (such as windows media player) and play a file on it without actually having to have windows media player installed?
so to clarify, can i play a windows media player in a webpage without having it installed? because at the moment the follwing bit of code only plays my files asfter i installed windows media player on my PC.
What ASP.NET page lifecycle event can I write code in to determine the size of the viewstate that being sent out? Also, is it possible to determine the size without parsing through the rendered HTML (like a property on the page object) or is parsing the only way?
What I'd like to do is log the sizes, specifically if they cross a certain threshold.
Does anyone know how to check in ASP.NET (C#) if Facebook is scraping a page? I'd like to be able to check on the server side if the "browser" hitting the page is actually Facebook (e.g. when it grabs details when a user is attempting to share a link).
I'm using Forms Authentication. Is there a way to determine whether a page (or request) required authentication or not? My site has logged-in areas, and logged-out areas (all set in web.config under authorization sections), and I'd like a good way to know if asp.net required authentication to be set or not.
I use a separate project for my data layer and call one class within it clsData.cs. I'd like to know which page from the Presentation Layer (in another project within the solution) has referenced it from the clsData side, if that's possible.
I've implemented this string format in my NavigateUrl to pass a dynamic querystring depending on the clicked item!
but you see the first part in the string format where it says "~/PLayer.aspx" i want the user control to automatically change this part according to where it's placed!
I have a MasterPage, several content pages - each of the content pages have a UserControl.
In the MasterPage, I'm setting the Page.Title programmatically based on Page_Init "Request.UserAgent.Contains....", so that the content pages end up with different page titles based on this.
Each content page has its Title set to blank (Title=" "), but when the page renders, the pragmatically generated page title shows up in the browser tab.
In the UserControl code behind, I need to access the content page's (parent page) Page.Title value, and base on this, display some text:
In other words, most pages require authentication and authorization, but some don't.
Then I have an IHttpModule that will be used by all the different applications. All I want to do is check if the current request is "secured" at all. If the page doesn't require authorization I don't want my IHttpModule to do anything at all. I am using FormsAuthentication and I assume that FormsAuthentication already has all of this information cached somewhere, doesn't it? Also, since this check will be running constantly so it has to be very quick.
I am currently subscribing to the HttpApplication.AuthorizeRequest, but surprisingly this event fires even for resources that allow anonymous access.
