I need to update the handler mappings on IIS 7.5 to allow URLs that don't have extensions to be routed to an application. The application was originally written in ASP.NET 2.0, but then later upgraded to ASP.NET 3.5. I don't know if that has relevance, but I've had no problem updating handler mappings for other .net 3.5 apps before. I should also note that this works fine on IIS 6.0
This is the error message I get when I click the Handler Mappings link in IIS 7.5 (notice there isn't really an error message as such, which would be helpful):
Handler Mappings
There was an error while performing this operation.
Details:
Filename: ?D:path oweb.config
Error:
OK
Has anyone seen this before? If you need more info, let me know and I'll supply.
How can I add a extension mappings in IIS6 which is actually a folder?I add an extension mappings of htm, jpg and gif for a 404 response, to be redirected to my custom page. however i have problem regarding in folder for example http://myweb/thumbnails/
I am busy developing an application using EF4 and MVC2. My development database has a few extra fields that is not in my production database. I have removed the fields from the Model, and published my application to my web server. But now I am getting errors that says I have some invalid column names, but I have removed it from my model. If I go to my Mapping Details, I see the fields removed from the Model are still there, but not mapped to anything.
I have confirmed that my Control Adapters are not triggering in Chrome and Safari. I've debugged, and the breakpoints inside the adapters just don't get hit in Chrome/Safari, when they work perfectly find in Firefox/IE. So, for Chrome/Safari, IIS is just ignoring the mapping.
This should provide mappings for all browsers, correct?
I used the Charles proxy to check what user agents were being sent. They are:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1064 Safari/532.5
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/531.22.7 (KHTML, like Gecko) Version/4.0.5 Safari/531.22.7
Any idea why this would be? Everything I've read tells me that my browser mappings are correct? And, as I said this works for IE/Firefox, so I know my configuration is technically correct.
I create custom HTTP handler for auto generating file and I want to tell IIS7 to serve current request like normal static file because I need to use IIS and web.config file to control compression setting and any other HTTP header of current requested file.I know. there is an internal class called StaticFileHandler in ASP.net. But I cannot access it. Or you have any other way to work like this.
Is there a technical reason for the existence of Page.PreLoad or is this just convenience to have a place where you can neatly place code that always have to be executed before the Load code? Is there a difference between adding code in the PreLoad event handler and adding code at the top of the Load event handler? And what would be a typical scenario where you use PreLoad?
In Visual Studio 2010, when you say new Item, you can see Asp.NET Handler and Generic Handler. Can you tell me what's the difference, I think it came with .NET 4.0 because I couldn't find related thins on Google.

When the user clicks on "OPEN" button, It should open up that(.txt) file which is on the file server in ReadWrite Mode (like in notepad) without any Access Issues.
Or simply has to be openend as temporary READONLY .Txt File. So that the user can close after viewing it.

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Response.Write("<script>") Response.Write("window.open('http://www.google.com','_blank')") Response.Write("</script>") End Sub
but I would not open the page immediately, but when given a click anywhere on the page, an example of what I do is [URL] need to click anywhere on the page to open a separate new page (pop up) and if you still go back to the site and give again a click anywhere on the page no longer loads the new page, I don't know if I'm being clear.

I'm trying to write an HTTP GET handler. The path should start with http://site/processTask and have a set of URL-encoded parameters. I have the following in my web.config
now when I type the URL http://mysite/processTask in browser I get HTTP 404 but if I change the add verb line to the following one:
<add verb="GET" path="processTask.asmx*" type="MyHandler.ProcessTaskHandler, MyHandler"/> and type http://mysite/ProcessTask.asmx in browser the handler is run and I get the response from the handler. What's the problem? Why is the handler run only when the path contains .asmx? How do I change web.config so that .asmx is not required?
I've got a simple ASHX handler that returns an dynamically generated image; the image is generated from a custom created class, and an object belonging to this class is passed to the handler using Session (I'd rather avoid using QueryString).The handler is used as the URL of an image on a ASP form which is very simple: a drop down list, a button and an image. Basically, depending on what the user selects from the list, the appropriate image will be generated once the button is pressed.
At the start the actual image has it's Visible property set to false; I don't want the handler to display anything before the data is all there.Once the button is pressed, the required Session parameter is added containing the necessary object, and the page is refreshed using Server.Transfer. When the Page_load method detects that the Session parameter has been correctly set, it sets the Visible parameter on the image to true.After that the handler fires up and generates the image.
So far so good... However, if the user now picks something different from the list and presses the button, despite the correct object being passed in the Session, the image won't be updated. In fact, the handler won't even fire up (if I put a breakpoint in there). I need to close the browser window and reopen it for it to work.Any ideas what could be the cause of such behaviour?I suspect the answer is very simple, and I just don't know something fundamental about ASP (or handlers)...
I am using ASP.NET Callbacks (that implements the ICallbackEventHandler) and in the handler, I try to set a value of the text box:
txtName.text = "Test";
but this value is not set. Is this a limitation with callback? It appears I cannot do much in a callback handler other than sending back a string to the client side (ofcourse I can access the Session etc)
