I am somewhat new to ASPX files, but I am not new to C#.
I figured that all asp.net c# projects were run on the server as compiled code. And so there was some sort of binary file somewhere somehow or maybe a XAP file like they have with silverlight.
But it seems that this is not the case. it seems that, sometimes, you can have an ASPX file along with the code-behing C Sharp file and it runs just like a PHP file. For starters, is that right? Am I right so far?
Now, if I was the owner of both the ASPX file and the CSHARP code-behind file, how would I go about debugging it in Visual Studio?
You have the web form, which is HTML and combinations of asp.net objects, similar to a PHP page
and code behind forms, that you write code in. asp.net objects can link to code behind using handlers, that point the code to the web form object.
The objects in asp.net, can be used 2 ways, on the web form as a HTML type of element, or in code behind in pure code.
When you run your project, asp.net will compile your code as various DLL files, and store them on the c drive under windows\Microsoft asp.net.
To debug your project, you press F5 using Visual Studio, you have to load the page you want to debug first, and set a break point by pressing F9 on the line of code you want. I think you can only debug code behind pages.
You can only debug a project or page that is on your hard drive, if the page you posted is crashing, then you have to look at the stack trace, and work your way down the list to find the line of code that bombed.
are you trying to reverse engineer the page?, or seriously need to fix something?
I thought this would be very simple. but I am not able to.
I tried simple code like this using href element. But it tries to open the sheet.xls in the browser window and says it can't find the file. I want the excel file to be opened in excel (not browser). Any suggestions?
<a href="file://domainname/vol1/destinationfiles/sheet.xls" >some excel file</a>
The excel file I am trying to open is not on IIS server. It is on file server.
Strange. I also thought it was easy.
But on my system, every call to a href="file:..." fails when the page containing the link was obtained via http.
Such links do work only when the page was opened with the file protocol. And the links do fail when the file to be opened is not on a local or mapped drive. Browsers offer to open the file (with Excel) when it is on a local/mapped drive or just download it.
I tested with current versions of Internet Explorer, Firefox, Chrome, Opera, and Safari.
The web server would most likely need to generate a local script with *application name hard coded*, then execute via a shell COM object. The local script can then do some remote checking of its own, and then launch the remote application. (Windows Script Host)
That's how I would try to do it.

I am having issues with maintaining info when person uses browser back button. I work for a company which is an online traffic school course. The issues I am having is say a student starts on lesson 1. Within lesson 1 there are 10 pages of content that they must read and click Next button to go to next page. Once they then have read all 10 pages, then they go to a quiz where they are given one question at a time (there are 5 questions). They click Next button to move to each question. Once they have answered all questions, then they go to a grade page. If they passed, then they click on continue button to go to lesson 2. Then onto quiz for lesson 2. This part all works great and if they click our programmed Back buttons everything works great as well. The problem is if they go from say lesson 1 all the way to lesson 3 (just an example) and they decide to use the browser's back button to go all the way back to lesson 1, everything tends to get messed up. Since we are driving off of class Student which contains current lesson num, current page num, current question num, once we advance further in the course these values get updated. My problem is that when the student continuously clicks the browser's back button the lesson num, page num and question num (and other content) does not follow suit to what it was. I am not sure why, but the pages are not being cached. Is there anyway to maintain the lesson num, page num and question num as the student clicks browser back button? Meaning as they click back to quiz from lesson 2, it shows lesson 2 (it is currently showing lesson 3 since that is how far have advanced) and same with the lesson pages that they must read. I have tried to use hidden input, but it does not seem to work correctly all the time. Any ideas???
I am not sure that I quite follow you. The students cannot move to next lesson with out moving through all of the pages of the lesson content and passing the quiz. So they do move forward in a linear manner. The problem is if they go all the way through lesson 1, pass lesson 1 quiz, now they go to lesson 2. If they now click the browsers back button all the way back to lesson 1 quiz question 1, that is where I seem to notice the problem. It shows lesson 2 quiz question 1. I would have thought that all the previous pages would be cached as the student clicks browser back button since it is only client side and is not going back to the server to retrieve any info. But for some reason it is not caching all of the pages. Is there a limit to the number of pages that will be cached?
You place a catch function in the page.load event of every page, that validates if that lesson was completed, and if so, it redirects them back to the lesson menu or a sorry page, then another redirect to the lesson menu.
You have to think 2 ways, one using your back and forward buttons, and one using the browsers back and forward buttons.
So you add some extra code for every lesson page, that first validates access to the page using the browser buttons.
Saving Page Number, Lesson Number data
You can save that in the session, but if they leave and come back, then the session number has to match, if they clear there browser cache, then the session is gone. The cache last as long as the browser will store it, or reaches it's storage limit, or until it's erased.
In my opinion, each page has to be independent in operation, in other words, the page has to be able to remember or fetch the data needed to pick up where it left off, without dependence of the previous page.
So overall I'm saying that it can't be fixed with something easy as remembering data in the session or querystring, it's at the program design level, in which each time an action occurs, it should update the table, and you check the table to figure out what level and lesson they are on.
Notice that there is a # (hash) symbol in the URL. The problem I'm having is that I have a 3rd party Grid on that page which is not operating correctly. If I manually change the URL to remove the # symbol, then the grid works perfectly.
Anybody know why this # symbol is showing up in my URL ? How can I get rid of it ?
I am using below bat file which should return output text as URLs which are NOT browsable(eg. page not found error) but it is actually returning all successful ping in output text.Please help me to modify my bat file:-
Of course not, that is not what ping is designed for. If you want to check individual web pages then you will have to write a program that sends and receives HTTP messages. Try a search of the articles section[^] for some examples.
Use the best guess
