I am launching a click once application on button click. I am using Response.Redirect(http://domain.com/application.application) to open my click once application. If I click on that button again then I am able to open one more instance of that application again. I want to put a restriction so user can open only one application.
View 3 RepliesI just recently installed VS 2008 on my workstation. I tried creating a simple web site just to check if the installation was fine. The project compiled without error but when I tried running it, the Macromedia Dreamweaver software is being launch. It tried it several time and it's all the same.I remember during the installation there was an option that was displayed asking me to select Designer or Coder. Since the default is Designer i just click next.
Is there a way to stop launching dreamweaver from VS 2008 every time i try running the web project? Is because I selected "Designer" during the installation?

I use a validation control to check if value entered is numeric. When I type letter in the textbox, the error messages shows for a second, then the application continues, and eventually throw exception.
I'm going to add server side validation in code behind. But I wonder why the validation control doesn't stop the application. I don't see any difference between this web form and other web forms where validation controls work fine.
I am using asp.net 3.5 and have validateRequest="true" in the machine.config.
Do I need to do something special to stop CSRF and Cross Site scripting or asp.net will handle all these?
Whenever I stop debugging an ASP.NET IIS web application it seems to take very long before VS2010 becomes responsive again (2 or 3 minutes). This happens when I close Internet Explorer 9 (which stops the debugging session), stop debugging in VS (which closes the browser) or when I detach the debugger from the debugging menu (which leaves the browser open).
My CPU time for devenv.exe goes up to 25% during this period of time. I use the professional edition (no intellitrace). Starting without debugging performs ok when I close the browser. I have some add-ins and extensions installed like TestDriven.NET, Resharper, PowerCommands, Productivity Power Tools, VisualSVN,...
Imagine a Web Forms application with routing.
A clean page name like:
[URL]
Might have an underlying of URL of:
[URL]
If a user enters [URL] into a browser, I need to redirect to [URL]
Is this possible to do?
I can't work out a way to do this as the routing engine is not executed for a physical page and in the page.aspx Page_Load method I have no way of knowing whether the URL was entered directly or was the result of a route.
This is a really odd situation, so hopefully I can explain it well enough.
I am deploying an ASP.NET 4 webforms application to a Windows Server 2003 SP2 server running IIS6.
Here's the problem -- when the application pool recycles its worker process (w3wp.exe), about 80% of the time, I will get an ReflectionTypeLoadException error trying to access any page in the app that contains an EntityDataSoure every time I try to view it.
However (this is the interesting part) -- the other 20%, it works just fine. I've actually resorted to turning off recycling the worker process entirely for this application pool and just add/remove whitespace from web.config forcing the site to recompile until I get a "good" w3wp.exe.
If this isn't clear, what I'm saying is: the actual worker process doesn't work at all for pages containing an EntityDataSource for about 4/5 times it starts, but still manages to serve all other pages just fine. Once you get a worker process that manages to serve a page with an EntityDataSource, it works every time until that process gets recycled.
My question is, how can I debug this? It works fine on my dev machine, it works fine on the server as long as you get a good process running, but iisreset or a server restart or anything that kills the worker process is almost guaranteed to cause the site to not come back up and throw this ReflectionTypeLoadException.

I have an app that outputs a gridview to excel spreadsheet and adds a couple of rows for accounting. I'm trying to launch the spreadsheet after its saved off, using
Code:
excelApp.ActiveWorkbook.SaveAs(filename);
excelApp.ActiveWorkbook.Saved = true;
excelApp.Quit();
var si= new ProcessStartInfo {FileName = filename, UseShellExecute = true}; //hits here and crashes
Process.Start(si);
it hits the marked line and crashes that it cant find the file, its automatically saving it to the documents folder on my local machine, and i cant seem to get it to save elsewhere (i have a data directory in the project i use for the other file types) that i would like to save to if possible, but it seems that if you have office installed it don't like it. i could always copy the file from documents to the datastore, but that's difficult.
how do i launch excel application using the file i just saved off to show to the bean crunchers?
