• Logging erros in SqlLite database from C# Windows Forms Application

  - by Ismail S

  I'm developing a win app in C# which communicates to a WCF Service. I want to log exceptions that are thrown on client to be logged in Sql Lite Database (Win app is using Sql Lite database for storing data locally). And then later it should be sent to the wcf service when required so that it can be useful for support/analysis/application improvement. I want a method which can be directly called in every catch block simply by LogHelper.Log(ex). I would like to know if anyone has done it through Enterprise library or used any good practice for such situation?

• How use applicationSettings in the new web.config configuration in VS2010?

  - by citronas

  I'm used to use web deployment projects. Currently I am developing a new web application with VS2010 and want to try to get along with the new web.config principle and deployment issues. How can I replace a simple setting like <applicationSettings> <NAMESPACE> <setting name="Testenvironment" serializeAs="String"> <value>True</value> </setting> </NAMESPACE> </applicationSettings> I want to have this setting to be set to True in Debug, and false in Release. How must the entries in the Web.Debug.config and Web.Release.Config look like? And by the way: Is there some documentation about the new web.config issue? Can't seem to google for the correct keywords.

• Facebook canvas app ASP.NET MVC HttpException: Invalid Model

  - by zznq

  I am working on a Facebook tab application. I am using asp.net MVC 2 with the "official" Microsoft Facebook SDK. Most of my views are working just fine. However, I have one that is causing a huge mess. I am simply returning a List<Tags> to the view and as my ViewModel. This problematic view is simply displaying the list in a foreach loop. Whenever navigate to this view I get a "System.Web.HttpException: Invalid Model" exception. The most puzzling part of all this is that the same code is running without fail on our regular(non-Facebook) app that works just fine with the same code. Any insight into why Facebook and asp.net MVC 2 would be causing this behavior would be much appreciated.

• How to stop the Bottle webserver when started from subprocess

  - by luc

  Hello all, I would like to embed the great Bottle web framework into a small application (1st target is Windows OS). This app starts the bottle webserver thanks to the subprocess module. import subprocess p = subprocess.Popen('python websrv.py') The bottle app is quite simple @route("/") def index(): return template('index') run(reloader=True) It starts the default webserver into a Windows console. All seems Ok except the fact that I must press Ctrl-C to close the bottle webserver. I would like that the master app terminates the webserver when it shutdowns. I can't find a way to do that (p.terminate() doesn't work in this case unfortunately) Any idea? Thanks in advance

• Restart IIS7 webapp for debug in VS2008

  - by spender

  I'm developing an ASP.NET asyc generic handler which uses a static System.Threading.Timer instance to feed data to the response output stream while the context is in the asynchronous phase. I'm having issues at startup that I'd like to debug. Currently, because of the long-lived nature of the timer, I'm manually killing w3wp.exe in order to cause the application to restart. I'm aware that there are other ways to do this, but this is the best workflow I can find! Isn't there a way to force a cold start when I hit f5, instead of the standard VS approach of attaching to the existing IIS process?

• Trying to run psexec to remote to server and recycle app pool

  - by James

  If I run this from my command prompt it works fine. psexec \ServerName cscript.exe iisapp.vbs /a AppName /r I'm trying to do the same thing with C# console app. I'm using the below code but most of the time the application hangs and doesn't complete, and the few times it does it throws an error code. Am I doing this wrong? Anyone know where I can look up the error or error code? static void RecycleAppPool(string sServer) { Console.Clear(); ProcessStartInfo p = new ProcessStartInfo("psexec.exe", "\\\\" + sServer + " cscript.exe iisapp.vbs /a <AppName> /r"); p.RedirectStandardInput = true; p.UseShellExecute = false; Process.Start(p); } When it completes with error, looks like this "cscript.exe exited with error code -2147024664"

• Best Practice - Validating Input In Simple GUI Application?

  - by Alex

  I'm writing a GUI app with wxwidgets in C++ for one of my programming classes. We have to validate input and throw custom exceptions if it doesn't meet certain conditions. My question is, what is best practice when it comes to this? Should I write a seperate function that checks for errors, and have my event handler's call that function? Or should I do my error-checking in my event handlers? Or does it really matter? Thanks!

• Website settings for running visual web as root?

  - by Curtis White

  Scott Gu explains how to run visual web developer using a root path, here: http://weblogs.asp.net/scottgu/archive/2006/12/19/tip-trick-how-to-run-a-root-site-with-the-local-web-server-using-vs-2005-sp1.aspx This worked exactly as he described in one instance for me. But, today I do not see this option. More over, I do not think I have a solution file, and I think that has something to do with it. I'm aware there are web application projects and web site model, and web site model is basically just a "directory". But can web site model, also, have a solution file for this setting or not a solution file? What determines that? I am interested in using this method on on a web site, i.e directory only model.

• Does all SPWeb or SPSite instances get automatically disposed when console app process has ended?

  - by Janis Veinbergs

  We have Best practices on using disposable object in SharePoint. But i`m thinking - can I skip these when using Console Application? That's some code I want to execute once and after that process has finished. Do or don't SPSite and SPWeb's remain opened somwhere? Why i`m asking this? I just don't want to stress when using something like var lists = from web in site.AllWebs.Cast<SPWeb>() where web is meeting workspace && list is task list select list then do some stuff on lists etc. Some serious resource leak there because webs get opened, filtered and NOT closed. So should I worry in console app?

• Is it faster to do the pages first and CSS second, or should I do them at the same time?

  - by Fred Haslam

  I have been tasked with building a new web project from scratch, with the exception of reusing CSS files (the look and feel) from an existing project. In the past I have always completed development of the functionality and the web-ui before considering the appearance. This is mostly due to CSS development overlapping with the tail end of the project. I now have the opportunity to integrate a static set of CSS as I build the application. I have no experience with this circumstance. Would it be faster to develop the project and web-pages first, then integrate the CSS; or would it be faster to integrate the CSS as part of page development?

• PHP: Facebook stream.publish and outdated template bundles?

  - by AFK

  Ok So I haven't tried messing with the facebook PHP API for months.. it's gross. Since template bundles are apparently now defunct, how can I publish a story into my users news feed for their friends? I've also already requested permissions. Edit: The issue seems to arise from requested permissions not being set for the user when They are granted. So far I have this $appapikey = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'; $appsecret = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'; $facebook = new Facebook($appapikey, $appsecret); $fb_user = $facebook->require_login(); try { $facebook->api_client->feed_publishUserAction(); } catch(Exception $e) { } edit: I've looked through the facebook "api documentation" multiple times it's just not clear to me. I can't tell what's actually deprecated or not. They link to tutorials 2-3 years old! if you have a problem with your iframe application reloading over and over and over try using $facebook-require_frame()

• Which Java web frameworks provide hot-reload?

  - by Stefane Fermigier

  I'd like to know which Java web application frameworks do provide a "hot reload" capability, i.e. allow to develop applications and have them redeployed on the server "almost instantly" (i.e. in less than a few seconds). I the Java world, Play! has it out of the box, but what I'm looking for is a more exhaustive list. Other examples that I'm aware of include: Nuxeo WebEngine, provided you're using Eclipse and the right plugin, or, in the Python world, Django and Pylons (when using the "--reload" option).

• Application_End() cannot access cache through HttpContext.Current.Cache[key]

  - by Carl J.

  I want to be able to maintain certain objects between application restarts. To do that, I want to write specific cached items out to disk in Global.asax Application_End() function and re-load them back on Application_Start(). I currently have a cache helper class, which uses the following method to return the cached value: return HttpContext.Current.Cache[key]; Problem: during Application_End(), HttpContext.Current is null since there is no web request (it's an automated cleanup procedure) - therefore, I cannot access .Cache[] to retrieve any of the items to save to disk. Question: how can I access the cache items during Application_End()?

• Creating standalone, console (shell) for domain-specific operations

  - by mr.b

  Say that I have a system service, and I want to offer a low-level maintenance access to it. For that purpose, I'd like to create a standalone, console application that somehow connects to server process and lets user type in commands, allow it to use auto-completion and auto-suggestion on single/double TAB press (just like linux bash shell, mysql cli, cmd.exe, and countless others), allow command line editing capabilities (history, cursor keys to move around text..), etc. Now, it's not that much of a problem to create something like that by rolling my own from scratch, handling user input, scanning pressed keys, and doing correct actions. But, why reinvent the wheel? Is there some library/framework that helps with this kind of problems, just like readline library that offers improved command-line editing capabilities under linux? Of course, this new "shell" would respond only to valid, domain-specific commands, and would suggest valid arguments, options, switches... Any ideas? Thanks!

• Using WINAPI ReadConsole

  - by Jim Fell

  I am trying to use the WINAPI ReadConsole() to wait for any keypress at the end of my Win32 console application. CONSOLE_READCONSOLE_CONTROL tControl; char pStr[65536]; DWORD dwBufLen = 1; DWORD dwCtl; tControl_c.nLength = sizeof( CONSOLE_READCONSOLE_CONTROL ); tControl_c.nInitialChars = 0; tControl_c.dwControlKeyState = 0; tControl_c.dwCtrlWakeupMask = NULL; pBuf[0] = 0x00; do { ReadConsole( hConsole_c, pStr, (*pBufLen) * sizeof(TCHAR), pBufLen, &tControl ); } while ( pStr[0] == 0x00 ); The code executes without throwing an exception. However, when the ReadConsole() function executes the error code ERROR_INVALID_HANDLE (0x06) is flagged. I have verified hConsole_c to be a valid handle. Does anyone have any insight as to what I am doing wrongly? I am using Visual C++ 2008 Express Edition. Thanks.

• Silverlight 3 and System.ServiceProcess - Doesn't allow the reference to be added.

  - by Brad8118

  I'm trying to write a program that can stop and start services using SilverLight 3 and VS2010. I can't add the reference to the System.ServiceProcess dll. C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.ServiceProcess.dll 1st why? - It it just a security precaution? 2- Is there a work around? Does SilverLight have a different library that I can use to start and stop services. Also note that this is a desktop application and not a web app. It will be sitting on my desktop to toggle services on and off.
