Debugging On A Built-in Web Server Suddenly Stops?
May 17, 2010
I have Windows Server 2008 (64-bit), VS 2008 with its built-in webserver and an ASP.NET MVC 1.0 webapp.All I'm trying to do is to debug said app. I have a bunch of breakpoints, but they behave in a very strange way. When I fist start a debugging session with F5 and hit a breakpoint, the debugger stops just fine. However, after serveral F10s/F11s debugging suddenly "stops" (no exceptions at that time), but neither VS detaches from browsers' process, nor webapp execution stops: Visual Studio stays attached, and web request continues executing as usual.I tried various browsers (Chrome, Firefox, IE), but to no avail.
Now that I am playing with NHibernate I am getting a lot more YSODs as I am learning it however I seem to get this error sometimesafter a YSOD:This webpage is not available The webpage at http://localhost:49497/ might be temporarily down or it may have moved permanently to a new web address.Error 139 (net::ERR_TEMPORARILY_THROTTLED):
Unknown error.Is there any way to disable this because I have to wait a few minutes every time and that is a pretty big killer is productivity?
This is not a big issue since it's quite easy to bypass by making a new project and copying everything on it, but it bothers me quite a bit that I can't figure out what it is about. In short my calendar and calendar extenders stop working suddenly. The last time this happened I made some changes to the pages code behind, then hit undo gazillion times to go back to the last save. After that I hit debug and lo and behold: calendar did not respond to any clicks and any text field with calendar extender did not show calendar on clicking them.
This happens in both IE8 and FireFox 3.6 and no amount or restart, rebuild and other such tricks do nothing. The only thing that I can figure out to solve the problem is either use a backup copy of a version that works or make a new project and then copy all the files from the not working into the new/earlier version and all works again. I was able to track down that this seems to relate somehow to AJAX as when I ran the debug I mention above, I got error messages on the web page saying something about AJAX. This however happened only once and I cant get it to happen again (and thus can not remember much about what it said).
Also when I debugged the event handling the calendar click, I get an error message like this: There is no source code available for the current location Then it opens a file search window trying to find some cs file inside the ajax control toolkit. However this only happened the first time I tried debugging the event and I can't remember more details about it. Now I just get that error message when debug exits the event.
So end analysis on my part: The ajax control tool kit gets knotted up all of a sudden for some mysterious reason and is tied to that particular project. Can anyone tell me what this could be about?
I have a problem debugging a web forms application that is configured to use IIS for debugging, under Windows 7 and Visual Studio 2010. An example has just occurred, where I make a change to the code behind for a web form, save, and apparently rebuild before starting the app using F5. The app starts, and I get an error message trying to do something in the app. I tell the debugger to break when an exception is thrown and try my task again, only to be told The source file is different from when the module was built. where the module is C:WindowsMicrosoft.NETFramework64v2.0.50727Temporary ASP.NET Files oot9d7b45ca11a98b19assemblydl35e6cf0b2636409d4_dfeecb01PerfixEMS_Admin.DLL
The physical folder for my test web site is set to the web application project's source folder, so I have always assumed that IIS will look in the bin folder for required assemblies, and these will be rebuilt as expected. Why is this not happening?
I have an ASCX component that has a lot of javascript declared in a script tag in the ascx itself. I can set breakpoints, and the debugger stops as it should, but the text that is highlighted in the debugger as the "current line" is nowhere near the actual javascript (it is much higher in the rendered file than it should be). I can "wing it" for one or two lines with the real code side-by-side with the "false" line of execution, but I lose all the hover abilities and everything else that makes javascript debugging useful.
I have tried putting the script at the top of my ascx file, but to no avail. I've tried not setting a breakpoint until the entire page is rendered, so that I have to scroll all the way to where the actual lines of code are, and the debugger still stops somewhere way above it.
I get this error when I hit F5 in VS 2008. I have checked that Windows authentication is enabled on the site and it is. I can mannully attach the debugger to the IIS process and it works. What could be wrong? I have tried alot of things without success.
I'm trying to debug my web application on my localhost machine in Visual Studio 2010 and I keep getting this error: "unable to start debugging on web server. The Microsoft Visual Studio remote debugging monitor(MSVSMON.exe) does not appear to be running on the remote computer."
Is there a way I can turn this off as I'm not trying to make any attempts debugging remotely.
I am running Visual Studio 2010 (as Admin), IIS 7 on Windows 7 x64. I am able to run the ASP.NET web site in IIS 7 without debugging just fine, but when I press F5 to debug it, I get: Unable to start debugging on the web server. Could not start ASP.NET debugging. More information may be available by starting the project without debugging. Unfortunately the help link is not helping me much and leads down a heck of a large tree of things. I checked the following:
Security requirements — I don't recall having to do anything special before. The worker process in IIS7 is w3wp.exe. It says that if it's running as ASPNET or NETWORK SERVICE I must have Administrator privileges to debug it. How do I find out if I need to change something here? Web site Property Pages > Start Options > Debuggers > ASP.NET is checked. Use custom server is set to the URL of the site (which works fine without debugging). Debugging is enabled in web.config. Application is using ASP.NET 3.5 (I want to move to 4.0 eventually but I have some migration to deal with). Application pool: Classing .NET AppPool (also tried DefaultAppPool). Surely it shouldn't be that hard to install IIS, VS, create a web site, and start testing it?
I'm running into a weird issue that I can't find an answer for anywhere I've looked (and I've looked a ton).I built a web deployment project with Visual Studio 2008 Team System on my old Win XP machine. This has always worked flawlessly and installed everywhere. I can also copy this MSI to my new Windows 7 Ultimate machine and it again installs just fine.
HOWEVER, when I rebuild that exact same web deployment project on my new Win7 machine, also using VS2008, the MSI will build OK, but when I then run it to install my software I get a dialog box telling me "the installer was interrupted." Interestingly, when I built this MSI in my new environment one additional warning popped up during the build process, which was "Unable to copy the schema file '(null)'"After many searches and reading different web pages, I know this has to do with these two registry keys:
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftVisualStudio9.0DeploymentSchema] "DefaultMSISchemaFile"="c:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools\Deployment\Vspkgs\..\VsdSchema\Schema.msi" "DefaultMSMSchemaFile"="c:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools\Deployment\Vspkgs\..\VsdSchema\Schema.msm"
Yet, everything checks out. All permissions are correctly configured, etc., etc.Then, when I enable the built-in administrator account and log in as that, and then rebuild this same web deployment MSI the "Unable to copy the schema file '(null)'" warning no longer appears. Then when I log back out, log back in as myself and then run this newly built MSI it installs fine, just like the original one that was built on XP.I also tried uninstalling VS2008 and re-installing it as the super user, but that also didn't change anything. And yes, I did also configure devenv.exe to run as administrator.
Has anybody seen this? Or is it a requirement that you can only compile deployment projects as the super user? That cannot be right.I've been thrashing for more than five days and for the life of me cannot figure this out. Of course, I can run as the super user when developing, but I thought the new security model in Win7 was designed exactly so you don't have to.
I'm using the full-text feature on SQL Server 2008 RC2. Everything had been working well until today. I wanted to change the language for word breakers from Neutral to Slovakia. After I did that, I can't perform full-text search anymore. It simply give me no rows. I even deleted the old full-text catalog and created a new one and populated it, but it still gave no solutions. I tried to query dm_fts_index_keywords_by_document on my table and get only 1 row with a display term END OF FILE.
I'm trying to write some code that checks the number of days between two dates, when I set the date on my IIS7 server to anytime in the future I get the standard "Internet Explorer cannot display the webpage" screen. This happens if I comment out all my date checking code, with todays date it loads with any future date it doesn't. I've tried rerunning IISReset which makes no difference.
When I'm trying to download a 50 MB file from a database (it is not an issue with a smaller file size), it stops in the middle sometimes and resumes again after a long time.
i have run one program in host server at a particular interval (lets say in each & every 1 hour) by using web service. but on my server web service stops automatically after 2 or 3 hour.
So we have three 2008 R2 Servers where two are configured to be web servers (IIS 7.5), and the third a session state server. I have set the SessionState and MachineKey settings in the applications web.config. After I restart the two web servers I can log into one server, then change the IP address to the other server, and I am still logged in. Success.
I can typically log in/out with any user account I want, change the ip address back and forth, and all is well until some random time between 30-60 minutes when I log in to one server, change the IP address, and the new server asks for credentials.
This is the sessionState setting in both web.configs:
The application resides under the default web site, and uses the default application pool. I am using forms authentication with a timeout of 20 minutes. I am not receiving any error events on any of the three servers when this happens, and restarting the two web servers fixes the problem for a while. The two web servers are not clustered per-se, but will be served round-robin via a network device.
When running the ASP.NET Development Server, everything is working fine. However, when I deploy my asp.net application to the production server (IIS 7.0 integrated mode, fresh install), my location tags in my web.config file are being ignored.
Case in point: I'm using forms authentication, and when the user arrives at my login.aspx page, the external css & js files are not being loaded...even though I have specified that those files should be available to all users (auth'd or not). However, once the user is logged in, the files do in fact load.
I am taking some time to learn how to develop asp.net mvc2 websites, but I'm used to working directly off IIS instead of the built-in web server that uses the random ports when you hit F5.
but I've noticed that using the built-in webserver, requests fly and are immediate. I am using only the default project with the Home and About pages as it comes out of the New ASP.NET MVC 2 Project settings, no database connections, nothing beyond the base install...
but when I setup the IIS website and pointed it to the same directory, each request takes at least 3-5 seconds to complete, sometimes more. this isn't just the "load" on the first request. EVERY request takes this long on IIS. but if I F5 and test the project once again, everything zips and the responses are immediate.
I run a web site with VB.Net and Sql Server, at a web host (so I use one instance of their Sql Server db). I now get this nasty message when trying to access the web site: Column 'kryptotext' does not belong to table tabellen. I have seen this before (but with other columns mentioned), and when I spoke to the tech guys they said that the server gives up after five (or so) invalid requests. The old problems I had were due to the fact that I had used Application variables - at least the problems appeared when I added the variable and diappeared when I deleted them.
This time, I have done very little. I ran a new check when some items of a gridview were databound, and if a condition was ok, then a mail should be sent and an update take place in the db. For now, this will not be true, so the new code doesn't fire, and I have now reverted to the old code anyway. I got htis message this morning, and then it has worked the entire day without me changing the code at all, and now it stopped working again, so to me it seems as if it's either not my code's fault, or I somehow flood the db server with requests (but the web site is new so there are really no users yet). One more thing I have added: I imported the Net.Mail namespace to the baseclass I'm using for the aspx pages, but I can't believe that has anything to do with this.
I asked the tech guys again, and the server has been working the whole day. Here's the web site: [URL] I am able to connect to the admin part of the web site, so it's just the public web site itself that doesn't run. What should I do? Edit: Now, 30 minutes later, it works again. I haven't done anything, in fact I had dinner now.
I'm debugging a site that is deployed to the site root on the production server, but in my local copy, under the built-in, debugging web server, the URL's include the 'site name'. E.g. my local site is 'PVLive', so all URL's are 'localhost:nnnnn/PVLive/mmmm.aspx'. Certain URL's are hard coded in the site's pages to use paths relative to the root, e.g. I get errors when code tries to redirect to 'localhost:nnnnn/Index.aspx'.
Can I do something to keep the 'PVLive' site name out of the URL's?
When I right click an ASPX page and click "View in Browser" the VS built-in web server starts up fine. However, if I go back to VS and make changes to the ASPX page and then refresh the browser, the changes are not reflected.
In order to see the changes, I have to stop the running web server and click "View in Browser" again to restart it -- then I can see the changes.
What's going on here? What would cause the built-in server (Cassini) to not reflect updates made from within Visual Studio? I also tried using UltiDev Cassini and am getting the same problem -- the web server does not load changes made in VS until the web server is restarted...
I am having issues debugging locally within Visual Studio 2010 on Server 2008 R2 (x64) for a new ASP.Net MVC application. I am able to debug using the VS Development Server (Cassini) but when I change to use the Local IIS Web Server and Create Virtual Directory, I am unable to debug. I get the standard VS message:
"Unable to start debugging on the web server. The web server is not configured correctly. ..."
Everything looks standard in IIS. The Default Web Site is running under the ASP.NET v4.0 application pool. The virtual directory that Visual Studio created is running under the same app pool. I am running Visual Studio as the Administrator account. It feels like some security setting or something is preventing this to work but I'm at a loss to what it could be.
I have a div called address which as a textarea. When I click a hyperlink, it toggles the div up and down. After clicking a an asp.net button the div collapses which is fine, but I noticed the url turns from [URL] to [URL] and now the toggle does not work. Here is the script:
the site normally works fine in all popular browsers including firefox, chrome, safari and ie.
but doesn't work in ie 8 when it's redirected via a proxy server and it gives an error saying
"Message: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near 'DOCTYPE html PUB'."
built a web service and pushed it to my production server. When I view the .asmx file I can see the methods listed and I can also test them fine using the generated forms.I am having an issue, however, when I attempt to test my web service by...(1) creating a new web app project (VB -- VS 2010).(2) creating a web reference (works fine).(3) calling the method by running it on my local machine.#1 and #2 are fine but it seems as if the web method never gets called (returns an empty string).
