By "how does" I mean "by what mechanism" not "to what effect". Control doesn't return to the calling method after you call Server.Transfer("...");. At the language runtime level, how does this happen? Does it throw an exception or trigger something that aborts the thread? I'm just curious. What are other examples of this pattern (calling a method to terminate execution)?
View 1 RepliesI need to check whether the request will return a 500 Server Internal Error or not (so getting the error is expected). I'm doing this:
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.Method = "GET";
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
if (response.StatusCode == HttpStatusCode.OK)
return true;
else
return false;
But when I get the 500 Internal Server Error, a WebException is thrown, and I don't want to depend on it to control the application flow - how can this be done?
How can I access the HttpServerUtility instance in ASP.NET MVC controller?
View 1 RepliesOne of my apps is to document aircraft inspection at mil sites. The discrepancy report for any one tail number can be many pages long. The description of the discrepancy in a gridview cell can be several lines. Therefore when the gridview hits the bottom of the physical page, the print spooler frequently splits the gridview row leaving part on one page and the rest at the top of the following page. I have done my due-diligence in research before posting but maybe I'm using the wrong words. I found something on CodeProject but it is too complicated for me. Does anyone have a simple solution? I use C# and am not very sharp with Java script.

I have a class which implements IHttpHandler that is designed to handle image resize requests. It handles Urls like so [URL] Currently the handler looks for myimg.jpg on disk, cuts a 100x100 thumbnail (if it isn't already present) and redirects the client to the thumbnail like so Response.RedirectPermanent("/some/virtualPath/to/thumbnail.jpg");
This has been working great, but I would like to avoid forcing the client to issue a second HTTP request. Is it safe to do the following? Server.Transfer("/some/virtualPath/to/thumbnail.jpg") All the MSDN documentation talks about using Server.Transfer() to redirect to an aspx page, so I'm not sure if this is the right thing to do or not.
I have a scenario in my application, by saving a text of length 20000 chars without line break in between.When i retrieve the same to an asp.net textbox control my UI is stretching to the length of these 2000 chars in a single line . I have to wrap the text automatically inside text box.

I have been doing Windows programming in .Net since last two years. Now I am shifting to web programming so I just stuck in understanding the fundamentals of web programming, after googling I came to StackOverflow to learn from all of you great guys.
My confusion is about how messages flow between systems in distributed enviornment ? I mean suppose I want to send a message "Hello" to a system connected to LAN or Internet, then what will be the steps taken to send the message.
Second thing is suppose my system is "A" and I wana send message to system "B" which is connected via a wire, so how the message flows on wire and how system "B" reads it from the wire ?
I've started using ASP.NET MVC on a project and have gotten a few working pages, but I recently ran into a problem where data I was carrying through a hidden field didn't carry for some reason. I can think of a couple of possible reasons and I could try things until something works but I prefer to work on observable empirical data. Thus the point of this inquiry.
I've got a controller (several), a model (several), a view (several), and data in the browser for the JavaScript to chew on. I can unit test my JavaScript code. The browser / view interactions go over the wire, and I can capture that either with Firebug or (if I want to punish myself) Ethereal. I can write unit tests for the controller and for components of the model. The thing that appears to happen in a pure "black box" is the mapping between the model objects and the view form fields. Somewhere in that process, it tries to map data from form fields into model objects before it hands a request to the controller and it tries to map data from the model objects to form fields when it processes the response. Even with the helpers in play, this is a source of bugs. There can be spelling disconnects, or a page might be inadvertently missing one of the fields of a model object because it didn't use it. It would be nice to know if a field didn't map and why.
Since it is happening on the server, this seems like the handoffs should be unit testable or at least loggable. The problem seems pretty bounded. I can't be the first person to have run into this question. Are there any hooks I can use for this? What are the best observation points in the framework to tap the process, both incoming and outgoing?
how to put what i am looking for. The best i can describe it is a flowchart type of layout that shows your all your ASP.NET pages and how they are linked to one another.

| login.asp| |footer.asp|
------------ /-----------
---------/ ------------
|Home.asp|---|Header.asp|
---------- ------------

--/----------- |Nav bar.asp|
|Products.asp| -------------
--------------
etc etc..

View 1 RepliesI am building a medium to large application with ASP.NET MVC 1.0 (we'll upgrade to the latest after we meet some schedule commitments). The application contains a number of workflows, with a separate controller for each workflow, and the home controller owning the main page of the application. So, I end up with the home page, on which the user makes selections and then clicks one of a number of action buttons to proceed down a given workflow. For a given workflow, I seem to have the following flow between controllers:
homeController (home view) --> action-button --> workflowController --> homeController (completion view)
I figure the action-button does a post to the home controller, which the selections the user made are saved to session state in the appropriate model. The workflowController will handle things as the user moves through one or more views specific to the workflow, but then things end on a common completion page.My question(s):1 - Is this a reasonable way to break up responsibilities amoung multiple controllers?2 - How do I actual accomplish the hand-off to the workflow specific controller? I'd really like to avoid a redirect and the attendent round trip to the browser since controller structure is really an internal implementation issue and shouldn't impose a performance penalty on the user.3 - Is it possible to pass a model from the originating controller to the destination controller, or do I have to exclusively depend on persistent state to pass things to the "next" controller?
if there's any documentation/resources the describes the complete process flow of an ASP.Net application? Looking for something that describes IIS handing off the HttpRequest and the usage of the PageParserFilters and such.
View 1 Repliesthis question should be fairly basic. I want to control the flow of an ASP.NET page -- if a certain condition is met, I want to write out an error message and stop drawing the page. However, I also want ASP.NET to output correct HTML (i.e. not cut off in the middle). Right now I am doing this:
if (condition != what-i-want) {
Label_Error.Text = "Sorry, you messed up";
return;
}
And the problem with that snippet is that ASP.NET draws the rest of the defined page without cutting off after the error. I really don't want to make the whole page Visible = False and then undo it when someone is authenticated. Is there some good way to do this? I have tried Response.End() but that doesn't output clean HTML (or anything actually, since I'm checking in Page_Load). I've had similar experiences with Response.Close(), et al.

View 2 RepliesOur site is expected to allow the user to do whatever they want from a number of different places. Except, that doing whatever they want really means firing off mini sequences of pages they must vist (or possibly abort from to go off to another task) before returning to their starting point. So, at any given time, the user has a list of pages they are allowed to go to, a list of pages they must go to in order to complete their task, and some end point they must eventually return to, all of which are constantly changing.
As an example, a user may choose to edit an order they placed, at which point they must step through a series of pages to edit the order. These pages to edit an order may be different based on the type of order they are editing, and they must return to whatever place they were at when they decided to start editing the order. They may also have certain options of other pages to visit during their order editing process.
I really need a good way to handle this for a large number of different scenarios, and allow it to be easily changed. Right now we are doing things like setting session variables when a user chooses an action and checking them within the page on button handlers to see what they are allowed to do or where they are allowed to go. I'd love to be able to abstract this out into something that can be easily examined in one place, or even data driven, and have some sort of navigation controller pointing them to the pages they can or must go.
