  • Console app showing message box on error

    - by holz
    I am trying to integrate with a vendors app by calling it with command args from c#. It is meant to automate a process that we need to do with out needing anyone to interact with the application. If there are no errors when running the process it works fine. However if there are any errors the vendors application will show a message box with the error code and error message and wait for someone to click the ok button. When the ok button is clicked it will exit the application returning the error code as the exit code. As my application is going to be a windows service on a server, needing someone to click an okay button will be an issue. Just wondering what the best solution would be to get around this. My code calling the vendor app is... ProcessStartInfo startInfo = new ProcessStartInfo(); startInfo.FileName = "someapp.exe" startInfo.Arguments = "somefile.txt"; Process jobProcess = Process.Start(startInfo); jobProcess.WaitForExit(); int exitCode = jobProcess.ExitCode;

  • Adobe Air update error "file version doesn't match" but it's the same!...

    - by baroquedub
    I'm using Claus Wahlers' AIR Remote Updater class (codeazur.com.br/lab/airremoteupdater/). All works fine and an update is triggered if the remote version is newer. The newer file is downloaded and the update starts. However I then get "an error has occured" message: "This application cannot be installed because this installer has been mis-configured" (The same file will update without errors when run manually "Would you like to replace the currently installed version?" Choosing 'replace' works fine) I have enabled Air Application Installer logging and I can see that both the app id and the pub id match - this seems to be a common reason for this problem (forums.adobe.com/thread/243421?tstart=60) The error given in the log file is as follows: AIR file version doesn't match Requested version: ; AIR file version: 1.0.2 But if I unzip the new app file and look at META-INF\AIR\application.xml the version designator shows <version>1.0.2</version> As requested! The log file is also showing me where the newer file is being downloaded and unpacked. If I look at the application.xml file in that directory: Unpackaging to C:\Documents and Settings\myusername\Local Settings\Temp\fla893D.tmp the version designator also shows <version>1.0.2</version> I don't get it?! The log tells me that the requested file version doesn't match but it's exactly the same as what's shown in the version designator of the downloaded update package... This is driving me crazy. Can anyone help?

  • Looking for a book which teaches how to write applications (as opposed to writng code)

    - by rumtscho
    I am not a developer. I have coded for fun and for university projects in several languages, and during an internship, I have written code which is still in use by a department of Fortune Global 500 company. I also have extensive theoretical knowledge of software engineering - process models, architecture, project management, UI construction using Lauesen's virtual windows... you get the picture. But I am not involved with software development in my job. I recently decided to start coding for fun again, and now I have some free days to do it. But this time, I want to do it right. I want to write a real, useful application, install it on my devices and use it myself. Also I want to publish it for others to use, should they want to do so. I am vaguely aware that there is more to writing an application than to writing code. There is stuff like version control software, decision for the right IDE, having a suite of unit tests, producing an installation package - and probably lots of other things I never thought of but which must be taken care of in a proper application, as opposed to a bunch of classes I am running from my IDE. All this is stuff I should know before I start, but I have not learned it. Coding books touch on some of the subjects like IDE choice, but don't go into detail, and are not exhaustive. Theoretical software engineering textbooks are even less helpful. So is there a book which teaches exactly that? I know that I can find information on each of these topics on the Internet, but I'd rather have a systematic book exhaustively listing all the things I should take care of if I want to create a good application, and offering the currently accepted solutions for them. In the best case, it will be language- and platform independent, but if you know of a good book focusing on a specific platform, I would like to know about it too. I know I want a lot, but given how important such knowledge is and how many people need it, surely somebody must have written such a book?

  • Pitfalls of the Architecture - Database based HTTP Request/Response Parsing

    - by Sam
    We have a current eCommerce Site that runs on ASP.NET and we hired a consultant to develop an new site bases on SOA. The new site architecture is as follows Web Application : Single Page Web Application (built on javascript/jquery templates - do not use any MVVM frameworks) that uses some javascript thrown all over the place. Service Layer : Very very light Service Layer that does not do anything other than calling a single stored procedure and pass in the entire http request. Database : The entire site content is in the database. The database does the heavy lifting of parsing the request and based on the HTTP method and some input parameter calls the appropriate Store Procedures or views and renders the result in JSON/XML. We have been told by them that this is built on latest and greatest technologies. I have a lot of concerns and of them given are the few Load on the Database SEO concerns for single page application as this is a public facing website Scalablity? Is this SOA? Cross Browser compatability (Site does not work in < IE9) Realistic implementaion of Single page application I know something is not right but I just need to validate my concerns here. Please help me.

  • InteropServices COMException when executing a .net app from a web CGI script on Windows Server 2003

    - by Kurt W. Leucht
    Disclaimer: I'm completely clueless about .net and COM. I have a vendor's application that appears to be written in .net and I'm trying to wrap it with a web form (a cgi-bin Perl script) so I can eventually launch this vendor's app from a separate computer. I'm on a Windows Server 2003 R2 SE SP1 system and I'm using Apache 2.2 for the web server and ActivePerl 5.10.0.1004 for the cgi script. My cgi script calls the vendor's app that resides on the same machine using the Perl backtick operator. ... $result = "Result: " . `$vendorsPath/$vendorsExecutable $arg1 $arg2`; ... Right now I'm just running IE web browser locally on the server machine and accessing "http://localhost/cgi-bin/myPerlScript.pl". The vendor's app fails and logs a debug message that includes the following stack trace (I changed a couple names so as to not give away the vendor's identity): ... System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException (0x80043A1D): 0x80040154 - Class not registered --- End of inner exception stack trace --- at System.RuntimeType.InvokeDispMethod(String name, BindingFlags invokeAttr, Object target, Object[] args, Boolean[] byrefModifiers, Int32 culture, String[] namedParameters) at System.RuntimeType.InvokeMember(String name, BindingFlags invokeAttr, Binder binder, Object target, Object[] args, ParameterModifier[] modifiers, CultureInfo culture, String[] namedParameters) at VendorsTool.Engine.Core.VendorsEngine.LoadVendorsServices(String fileName, String& projectCommPath) ... When I run the vendors app from the Windows command line on the server machine with the exact same arguments that the cgi script is passing it runs just fine, so there's something about invoking their app via the web script that is causing a problem. This problem is likely security related because the whole thing runs just fine on a Windows XP Pro machine (both command line and web invocation). I actually developed my web script there and got it completely working there before I tried moving it to the Windows Server 2003 machine. So what's different about the Windows Server 2003 machine that would keep the vendor's .net app from being executed successfully by a web cgi script? Can I fix this problem somehow to make it work on my server or will the vendor have to make a change to their .net app and ship out a new version? I'm probably the only person in the world who is trying to execute this vendor's app from a separate program, so I hate to bother the vendor with the issue if there's a workaround that I can implement myself here on my server machine. Plus, I'm in kind of a hurry and I don't want to wait 4 or 6 months for the vendor to put in a fix and deploy a new version. Thanks for any advise you can give.

  • Login failed for user 'DOMAIN\MACHINENAME$'

    - by sah302
    I know this is almost duplicate of : http://stackoverflow.com/questions/1269706/the-error-login-failed-for-user-nt-authority-iusr-in-asp-net-and-sql-server-2 and http://stackoverflow.com/questions/97594/login-failed-for-user-username-system-data-sqlclient-sqlexception-with-linq-i but some things don't add up compared to other appliations on my server and I am not sure why. Boxes being used: Web Box SQL Box SQL Test Box My Application: I've got aASP.NET Web Application, which references a class library that uses LINQ-to-SQL. Connection string set up properly in the class library. As per http://stackoverflow.com/questions/97594/login-failed-for-user-username-system-data-sqlclient-sqlexception-with-linq-i I also added this connection string to the Web Application. The connection string uses SQL credentials as so (in both web app and class library): <add name="Namespace.My.MySettings.ConnectionStringProduction" connectionString="Data Source=(SQL Test Box);Initial Catalog=(db name);Persist Security Info=True;User ID=ID;Password=Password" providerName="System.Data.SqlClient" /> This connection confirmed as working via adding it to server explorer. This is the connection string my .dbml file is using. The problem: I get the following error: System.Data.SqlClient.SqlException: Login failed for user 'DOMAIN\MACHINENAME$'. Now referencing this http://stackoverflow.com/questions/1269706/the-error-login-failed-for-user-nt-authority-iusr-in-asp-net-and-sql-server-2 it says that's really the local network service and using any other non-domain name will not work. But I am confused because I've checked both SQL Box and SQL Test Box SQL Management Studio and both have NT AUTHORITY/NETWORK SERVICE under Security - Logins, at the database level, that isn't listed under Security - Users, but at the database level Security - Users I have the user displayed in the connection string. At NTFS level on web server, the permissions have NETWORK SERVICE has full control. The reason why I am confused is because I have many other web applications on my Web Server, that reference databases on both SQL Box and SQL Test Box, and they all work. But I cannot find a difference between them and my current application, other than I am using a class library. Will that matter? Checking NTFS permissions, setup of Security Logins at the server and databases levels, connection string and method of connecting (SQL Server credentials), and IIS application pool and other folder options, are all the same. Why do these applications work without adding the machinename$ to the permissions of either of my SQL boxes? But that is what the one link is telling me to do to fix this problem.

  • Automatically extracting inline XSD from WSDL into XSD file(s)

    - by Steven Geens
    I am using a third party Web Service whose definition and implementation are beyond my control. This web service will change in the future. The Web Service should be used to generate an XML file which contains some of the same data (represented by the same XSD types) as the Web Service plus some extra information generated by the program. My approach: create my own XSD referring to the XSD definitions of the WSDL of the called web service (This XSD also includes XSD types for the extra information obviously.) use a Java XML databinding framework (like ADB or JiXB) to generate the databinding classes from my own XSD file from step 1 use a Java SOAP framework (like Axis2 or CXF) with the same databinding framework to generate the databinding classes from the WSDL (This would enable me to use the objects retrieved by the web service directly in the generation of the XML.) The XSD types I am going to use in my own XSD file, but are defined in the WSDL, are subject to change. Whenever they change, I would like to automatically process the XSD and WSDL databinding again. (If the change is significant enough, this might trigger some development effort.(But usually not.)) My problem: In step 1 I need an XSD referring to the same types as used by the Web Service. The WSDL is referring to another WSDL, which is referring to another WSDL etc. Eventually there is an WSDL with the needed inline XSD types. As far as I know there is no way to directly reference the inline XSD types of a WSDL from an XSD. The approach I would think most viable, is to include an extra step in the automatic processing (before the databinding) that extracts the inline XSD from the WSDL into other XSD file(s). These other XSD file(s) can then be referred to by my own XSD file. Things I'd like to avoid: Manually copy pasting the inline XSD into an XSD file (I am looking for an automatic process.) Any manual steps.(Like the determining the WSDL that contains the inline types manually.(The location of that WSDL does change as well.)) Using xsd:any in my own XSD. I would like my own XSD file to be correct. Using a non-Java technology(like .NET) Huge amounts of implementation (but hints on how you would implement such an extraction are welcome anyway) PS: I found some similar questions, but they all had responses like: WTH would you want to do that? That is the reason for my rather large background story.

  • "Bad binary signature" in ASP.NET MVC application

    - by David M
    We are getting the error above on some pages of an ASP.NET MVC application when it is deployed to a 64 bit Windows 2008 server box. It works fine on our development machines, though these are 32 bit XP. Just wondered if anyone had encountered this before, and has any suggestions? Details as follows: Bad binary signature. (Exception from HRESULT: 0x80131192) Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Runtime.InteropServices.COMException: Bad binary signature. (Exception from HRESULT: 0x80131192) All projects are set to compile for Any CPU, and are compiled in Release mode. The ASP.NET site is precompiled, and the precompiled build is on a 64 bit Windows 2008 TeamCity build agent. Thanks in advance. EDIT We're still plagued by this. I have looked at all the binaries in the website's bin directory using corflags.exe. None has the 32BIT flag set, and all have a CorFlags value of 9 except for Antlr3.Runtime.dll which has a value of 1. The problem only affects certain pages, and it seems to be those which use FluentValidation (including FluentValidation.Mvc and FluentValidation.xValIntegration assemblies). None of these shows anything out of the ordinary when inspected with corflags.exe, and there are no odd looking dependencies revealed by ildasm. When built locally (32 bit Windows XP) the site deploys and runs fine. When built on the build agents (64 bit Windows 2008 Server) the site displays these errors. The site runs in Integrated Pipeline mode, and is not set to 32 bit. The stack trace is: [COMException (0x80131192): Bad binary signature.

  • Can I create a custom roleprovider through a WCF service?

    - by RJ
    I have a web application that accesses a database through a wcf service. The idea is to abstract the data from the web application using the wcf service. All that works fine but I am also using the built in roleprovider using the SqlRoleManager which does access the aspnetdb database directly. I would like to abstract the roleprovider by creating a custom roleprovider in a wcf service and then accessing it through the wcf service. I have created the custom role provider and it works fine but now I need to place it in a wcf service. So before I jump headlong into trying to get this to work through the WCF service, I created a second class in the web application that accessed the roleprovider class and changed my web config roleprovider parameters to use that class. So my roleprovider class is called, "UcfCstRoleProvider" and my web.config looks like this: <roleManager enabled="true" defaultProvider="UcfCstRoleProvider"> <providers> <add name="UcfCstRoleProvider" type="Ucf.Security.Wcf.WebTests.UcfCstRoleProvider, Ucf.Security.Wcf.WebTests" connectionStringName="SqlRoleManagerConnection" applicationName="SMTP" /> </providers> </roleManager> My class starts like this: public class UcfCstRoleProvider : RoleProvider { private readonly WindowsTokenRoleProvider _roleProxy = new WindowsTokenRoleProvider(); public override string ApplicationName { get { return _roleProxy.ApplicationName; } set { _roleProxy.ApplicationName = value; } } As I said, this works fine. So the second class is called BlRoleProvider that has identical properties and parameters as the roleprovide but does not implement RoleProvider. I changed the web.config to point to this class like this: <roleManager enabled="true" defaultProvider="BlRoleProvider"> <providers> <add name="UcfCstRoleProvider" type="Ucf.Security.Wcf.WebTests.BlRoleProvider, Ucf.Security.Wcf.WebTests" connectionStringName="SqlRoleManagerConnection" applicationName="SMTP" /> </providers> </roleManager> But I get this error. "Provider must implement the class 'System.Web.Security.RoleProvider'." I hope I have explained well enough to show what I am trying to do. If I can get the roleprovider to work through another class in the same application, I am sure it will work through the WCF service but how do I get past this error? Or maybe I took a wrong turn and there is a better way to do what I want to do??

  • How can I call VC# webservice methods without ArgumentException?

    - by Zarius
    Currently, I'm trying to write a small tray application that will show the status and provide control of a server-side application exposed over webservice. The webservice only has 3 operations: start, stop and status. When I call any of these operations in code, they throw an ArgumentException citing "An item with the same key has already been added". I am compiling the webservice on Visual C# Express 2008, and .NET 3.5.

  • ASP.Net JSON Web Service Post Form Data

    - by Will D
    I have a ASP.NET web service decorated with System.Web.Script.Services.ScriptService() so it can return json formatted data. This much is working for me, but ASP.Net has a requirement that parameters to the web service must be in json in order to get json out. I'm using jquery to run my ajax calls and there doesn't seem to be an easy way to create a nice javascript object from the form elements. I have looked at serialiseArray in the json2 library but it doesn't encode the field names as property name in the object. If you have 2 form elements like this <input type="text" name="namefirst" id="namefirst" value="John"/> <input type="text" name="namelast" id="namelast" value="Doe"/> calling $("form").serialize() will get you the standard query string namefirst=John&namelast=Doe calling JSON.stringify($("form").serializeArray()) will get you the (bulky) json representation [{"name":"namefirst","value":"John"},{"name":"namelast","value":"Doe"}] This will work when passing to the web service but its ugly as you have to have code like this to read it in: Public Class NameValuePair Public name As String Public value As String End Class <WebMethod()> _ Public Function GetQuote(ByVal nvp As NameValuePair()) As String End Function You would also have to wrap that json text inside another object nameed nvp to make the web service happy. Then its more work as all you have is an array of NameValuePair when you want an associative array. I might be kidding myself but i imagined something more elegant when i started this project - more like this Public Class Person Public namefirst As String Public namelast As String End Class which would require the json to look something like this: {"namefirst":"John","namelast":"Doe"} Is there an easy way to do this? Obviously it is simple for a form with two parameters but when you have a very large form concatenating strings gets ugly. Having nested objects would also complicate things The cludge I have settled on for the moment is to use the standard name value pair format stuffed inside a json object. This is compact and fast {"q":"namefirst=John&namelast=Doe"} then have a web method like this on the server that parses the query string into an associate array. <WebMethod()> _ Public Function AjaxForm(ByVal q As String) as string Dim params As NameValueCollection = HttpUtility.ParseQueryString(q) 'do stuff return "Hello" End Sub As far a cludges go this one seems reasonably elegant in terms of amount of code, but my question is: is there a better way? Is there a generally accepted way of passing form data to asp.net web/script services?

  • How build my own Application Setting

    - by adisembiring
    I want to build a ApplicationSetting for my application. The ApplicationSetting can be stored in a properties file or in a database table. The settings are stored in key-value pairs. E.g. ftp.host = blade ftp.username = dummy ftp.pass = pass content.row_pagination = 20 content.title = How to train your dragon. I have designed it as follows: Application settings reader: interface IApplicationSettingReader { read(); } DatabaseApplicationSettingReader { dao appSettingDao; AppSettings read() { List<AppSettingEntity> listEntity = appSettingsDao.findAll(); Map<String, String> map = new HaspMap<String, String>(); foreach (AppSettingEntity entity : listEntity) { map.put(entity.getConfigName(), entity.getConfigValue()); } return new AppSettings(map); } } DatabaseApplicationSettingReader { dao appSettingDao; AppSettings read() { //read from some properties file return new AppSettings(map); } } Application settings class: AppSettings { private static AppSettings instance; private Map map; Public AppSettings(Map map) { this.map = map; } public static AppSettings getInstance() { if (instance == null) { throw new RuntimeException("Object not configure yet"); } return instance; } public static configure(IApplicationSettingReader reader) { instance = reader.read(); } public String getFtpSetting(String param) { return map.get("ftp." + param); } public String getContentSetting(String param) { return map.get("content." + param); } } Test class: AppSettingsTest { IApplicationSettingReader reader; @Before public void setUp() throws Exception { reader = new DatabaseApplicationSettingReader(); } @Test public void getContentSetting_should_get_content_title() { AppSettings.configure(reader); Instance settings = AppSettings.getInstance(); String title = settings.getContentSetting("title"); assertNotNull(title); Sysout(title); } } My questions are: Can you give your opinion about my code, is there something wrong? I configure my application setting once, while the application start, I configure the application setting with appropriate reader (DbReader or PropertiesReader), I make it singleton. The problem is, when some user edit the database or file directly to database or file, I can't get the changed values. Now, I want to implement something like ApplicationSettingChangeListener. So if the data changes, I will refresh my application settings. Do you have any suggestions how this can be implemented?

    I'm reorganzing a legacy mixed (managed and unmanaged DLLs) application so that the main application segment is unmanaged MFC and that will call a C++ DLL compiled with /clr flag that will bridge the communication between the managed (C# DLLs) and unmanaged code. Unfortuantely, my changed have resulted in an Access violation that occurs before the application InitInstance() is called. This makes it very difficult to debug. The only information I get is the following stack trace. > 64006108() ntdll.dll!_ZwCreateMutant@16() + 0xc bytes kernel32.dll!_CreateMutexW@12() + 0x7a bytes So, here are some sceanrios I've tried. - Turned on Exceptions-Win32 Exceptions-c0000005 Access Violation to break when Thrown. Still the most detail I get is from the above stack trace. I've tried the application with F10, but it fails before any breakpoints are hit and fails with the above stack trace. - I've stubbed out the bridge DLL so that it only has one method that returns a bool and that method is coded to just return false (no C# code called). bool DllPassthrough::IsFailed() { return false; } If the stubbed out DLL is compiled with the /clr flag, the application fails. If it is compiled without the /clr flag, the application runs. - I've created a stub MFC application using the Visual Studio wizard for multidocument applications and call DllPassthrough::IsFailed(). This succeeds even with the /clr flag used to compile the DLL. - I've tried doing a manual LoadLibrary on winmm.lib as outlined in the following note Access violation when using c++/cli. The application still fails. So, my questions are how to solve the problem? Any hints, strategies, or previous incidents. And, failing that, how can I get more information on what code segment or library is causing the access exception? If I try more involved workarounds like doing LoadLibrary calls, I'd like to narrow it to the failing libraries. Thanks. BTW, we are using Visual Studio 2008 and the project is being built against the .NET 2.0 framework for the managed sections.

  • Pass param to a silverlight application

  • Application not showing up in Google Play for 4.x devices

    - by Zargle
    I recently posted about the Play store not letting me publish my app without a minSdkVersion, but whenever I set it to anything above "1" my app just doesn't work (minSdkVersion breaking program). So this guy suggested to just set my minSdkVersion to 1, which worked. But now when I submitted my app even though the developer site says: API level: 1-16+ Supported screens: normal-xlarge OpenGL textures: all But the app only shows it supports Android under 4.x, I developed it on my 4.0.4 device. I tried searching around and I found that some people have problems with services messing up the phones it supports, so I deleted all of my services, because I don't really need any for this version of the app to submit. And it still didn't work. So I don't know what else to do, here is my AndroidManifest.xml if it helps... I've been trying to figure out why my application isn't working for a week now, still nothing. I have tried setting a targetSdkVersion to something like 14, my application still breaks. I cleaned out my code, taking everything out of the already short, 200 lines, application, and it still isn't working. Is there something I can't use in an android application 4.0 that I am using in my application? or is it just my AndroidManifest? Thank you so much! <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.unparalleledsoftware.app.list" android:versionCode="5" android:versionName="2.02" > <uses-sdk android:minSdkVersion="1" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name=".MainActivity" android:label="@string/title_activity_main" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> I should note,I am using the Theme.Holo.Light, but even if I change it to DeviceDefault it doesn't work. Edit: I googled the app on my friends Samsung Galaxy S3 (it didn't show up in the Play Store on his phone), when I installed by googling the app and hitting the "install" button on google and it opened in the Google Play store and was able to install. When I did the same on my phone, Galaxy Note, it opened in the Google Play Store, but then said "Not compatible." Why? They are both on the same version of OS. Why is mine not compatible, nor the One X compatible, but the Samsung Galaxy S3 worked...? Edit: I get these errors/problems when compiling with a targetSdkVersion, http://pastebin.com/mxgWNLdM

  • AllowSetForegroundWindow & SetForegroundWindow: NPAPI plug-in wants to allow a desktop application with no success

    - by David Robert Jones
    Here it's what I have: a web browser plug-in written in C++ and a Windows application written in C#. They communicate through a named pipe. The plug-in instructs the C# application to open a file (suppose that the file is a .txt and it opens in Notepad). Once the C# application is given the command, it opens the file but Notepad doesn't show in the foreground, which isn't acceptable, I must open Notepad in the foreground. I modified the C# application so that it calls the SetForegroundWindow function. This time Notepad didn't open in the foreground, but the taskbar flashes. After reading the documentation for SetForegroundWindow and many articles I think that now I understand what the problem is: the C# application can't bring Notepad to the foreground because it wasn't the the foreground process, the browser was (?). After reading this: "A process that can set the foreground window can enable another process to set the foreground window by calling the AllowSetForegroundWindow function." I decided to modify the plug-in. This time the plug-in calls the AllowSetForegroundWindow function passing ASFW_ANY as a parameter (I know, ASFW_ANY could be risky, but I wanted to make sure that AllowSetForegroundWindow would do it). After I did the modification to the plug-in I tested it and it worked! (Opera 12.02). Then I tested it on Internet Explorer and it worked too. But the problem came when I tested it in Firefox and Chrome. The C# application didn't have the ability to bring Notepad to the foreground. I noticed that for those browsers the AllowSetForegroundWindow function was returning false. So I started investigating and I come to the conclusion that maybe it's because the plugin container that Firefox uses. An idea came to my mind: it worked in Opera 12.02, but they don't have a plugin container, although they did in Opera 12.00. So I downloaded Opera 12.00, I did the test and it failed, which makes me conclude that the plugin container is the culprit. The question is: how can I give to the C# application the ability to set foreground? I don't know how to continue, and I think that I tried all the legitimate ways. The AllowSetForegroundWindow & SetForegroundWindow seems to not apply here.

  • I would like to prevent these entries from being added to the eventlog.

    - by David Smith
    Our client's application EventLog is getting filled up with warnings due to a bug in the Microsoft SQL Server report viewer control, http://support.microsoft.com/kb/973219. They have thousands of users running reports so this is making their eventlog hard to use and they want them removed on a frequent basis. I tried using PowerShell to remove the events, but that does not seem possible. Is there a way to prevent these entries from being written to the event log in the first place? I'm thinking I would like to filter out events where event source="ASP.NET 2.0.50727.0", eventId ="1309" and Message contains "Reserved.ReportViewerWebControl.axd"

  • How to assign permissions to ApplicationPoolIdentity account

    - by Triynko
    In IIS 7 on Windows Server 2008, application pools can be run as the "ApplicationPoolIdentity" account instead of the NetworkService account. How do I assign permissions to this "ApplicationPoolIdentity" account. It does not appear as a local user on the machine. It does not appear as a group anywhere. Nothing remotely like it appears anywhere. When I browse for local users, groups, and built-in accounts, it does not appear in the list, nor does anything similar appear in the list. What is going on? I'm not the only one with this problem: see Trouble with ApplicationPoolIdentity in IIS 7.5 + Windows 7 for an example. "This is unfortunately a limitation of the object picker on Windows Server 2008/Windows Vista - as several people have discovered it already, you can still manipulate the ACL for the app-pool identity using command line tools like icacls."

  • Does it actually matter whether you have open applications when installing new software?

    - by Dan
    It seems the norm these days is for installers/setup programs to request that you close all open applications before initiating the install process for a piece of new software. I used to obediently follow these directions without fail, even though it could sometimes be frustrating having to close open documents and stop working on things just to get a new, seemingly unrelated application installed. Then at some point I simply stopped bothering. Nowadays if I have a lot of stuff going on I might even run multiple installers at the same time; I can't even recall a time it has ever posed a problem. Why do setup programs even make this request in the first place, then, when it appears to be unnecessary? Is this just to simplify troubleshooting for companies' support people? Has anyone else ever run into problems as a result of trying to install an app while other apps were open?

  • Does scheduling recycling app pool in IIS7 help the server conserve memory better?

    - by user29266
    Hello, I have a VPS (IIS7 with Win 2008) It's got: 40 websites and a SQL Server 2008 powering them with only 2 Gigs of RAM. None of the sites are mission critical, they are all just demos. I often have ram issues on the server because each site has does caching and generally uses a lot of memory. Would it make sense to set the application pools to recycle every 3 hours? I'm sure this would free up any memory leaks or processes left "hanging" Are there any other tips on this? Thank you very much!, Aron

  • Session Variables lost between pages reloads

    - by Android Addict
    I was forced to move to IIS 7 when the server running our IIS 6 died. Nothing in the web app has changed, but it's obvious the environment has dramatically. The app fails between pages because the session variables are lost during redirect. I am not an expert on app pools but my impression from reading several posts is that the app pool is being recycled immediately. While they give a reason, they offer no help in how to resolve this. Can someone explain to a newb how to properly configure the DefaultAppPool?

  • IIS7.5 App Pool recycling. What is the best schedule for Recycling

    - by mikedopp
    I have been using IIS7.5 Since its release. I am also using commerce server 2007sp2. Due to Commerce Servers Need for memory and processor I have the app pool the website is assigned to recycling at midnight every night. My Question is what is the best time table to recycle heavy web app pools? I am looking to keep speed and not bump potential customers while recycling multiple times a day if possible. Another issue is that every few days the same app pool will hang and I have to force a reset of IIS to get it working again.

  • Problem identifying which page/page/function locks whole IIS server

    - by fnovak
    Hello, I have problem identifying which page/page/function locks whole IIS server. Out of the blue whole w3wp.exe jumps to CPU 90-98% usage. I have created 3 different application pools to see which w3wp.exe service locks the processor but I am unable to find out this information. I can only see that 2 of 3 services have 0-5% usage and one is jumping around 90-98% after some while. I think some process/function/redirect/sql is doing this but I would like to eliminate it. So far I am not even able to find the source of the problem. On my local development machine with VS2010 everything works like charm and I am unable to replicate problem. The server is windows 2k3 web server, sql server 2k5 and .net 4.0 Thank you for your help, links or any information on this issue. Fero
