• System.Security.VerificationException: Operation could destabilize the runtime

  - by Rigobert Song

  I have a web service which is queried using linq to sql but returns an array of objects. I keep getting the following error: System.Security.VerificationException: Operation could destabilize the runtime When I run a method that uses a linq statement to return an array I get this error, but only on my test server, which is windows server 2008. Everything works fine in my win 7 machine. The project is a .net 3.5. Any ideas what the problem might be? Thanks UPDATE: My linq queries return IQueryable.

• Unknown runtime error number: -2146827687

  - by Simone Vellei

  I have an error in my GXT code on Internet Explorer (both Development Mode and not) when i try to attach a label to a panel. The error is "Unknown runtime error number: -2146827687" but this error in a GWT module is throws always, in other gwt modules with a label attached to the panel the error there isn't. The layout of panel is a GridFormLayout developed by me. The error is thrown when the renderComponentInCell is called (the method is called on doLayout) and the component is not rendered (else condition). private void renderComponentInCell(Component component, Element cell) { if (component.isRendered()) { cell.appendChild(component.getElement()); } else { component.render(cell); } } What can I do?

• C# Assembly not found at runtime

  - by Gustavo Cardoso

  A strange error begans to happen with my XNA project on a new pc. I have two projects on the solution and a library that is used by both of them. One of the projects, a XNA Game Project, runs perfectly. The other project is a mix of WindowsForm and XNA. The form launches a XNA class when a button is clicked. When I run the program, it works great till the moment I click the button which launch the XNA class. A FileNotFoundException is fired exactly at the moment that the constructor will be executed. System.IO.FileNotFoundException was unhandled Message="Could not load file or assembly 'Microsoft.Xna.Framework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=6d5c3888ef60e27d' or one of its dependencies. The system cannot find the path specified." The reference is correct, there is no problem on compilation. We already tried to delete the reference and add it again but it didn't work. Everything worked correctly in others teammate's pc. Anyone has any idea what is the problem?

  I am trying to run Cygwin, and I am running into some problems. I tried to compile a program that works both on Windows with mingw and on a Unix system, but when I go to compile it through Cygwin: gcc threads.c -o threads I get the error: this application has requested the runtime to terminate it in an unusual way And that's it... any ideas what I am forgetting or screwing up? I haven't touched this stuff in about 5 years so I am beyond rusty; thanks!

• Jquery runtime error: object expected

  - by Joris

  The Jquery script that controls my tabcontainer gives an "object expected" runtime error. I honestly can't find the reason why: $(document).ready(function() { //When page loads... $(".tab_content").hide(); //Hide all content $("ul.tabs li:first").addClass("active").show(); //Activate first tab $(".tab_content:first").show(); //Show first tab content //On Click Event $("ul.tabs li").click(function() { $("ul.tabs li").removeClass("active"); //Remove any "active" class $(this).addClass("active"); //Add "active" class to selected tab $(".tab_content").hide(); //Hide all tab content var activeTab = $(this).find("a").attr("href"); //Find the href attribute value to identify the active tab + content $(activeTab).fadeIn(); //Fade in the active ID content return false; }); }); Has it something to do with the stylesheet?

• Assign binding path at runtime in WPF DataTemplate

  - by Abiel

  I am writing a WPF program in C# in which I have a ListView for which the columns will be populated at runtime. I would like to use a custom DataTemplate for the GridViewColumn objects in the ListView. In the examples I have seen where the number of columns is fixed in advance, a custom DataTemplate is often created using something like the XAML below. <DataTemplate x:Key="someKey"> <TextBlock Text="{Binding Path=FirstName}" /> </DataTemplate> This DataTemplate could also later be assigned to GridViewColumn.CellTemplate in the code-behind by calling FindResource("someKey"). However, this alone is of no use to me, because in this example the Path element is fixed to FirstName. Really I need something where I can set the Path in code. It is my impression that something along these lines may be possible if XamlReader is used, but I'm not sure how in practice I would do this. Any solutions are greatly appreciated.

• Need to get .obj file names of Executable(which one is crrently executing) at runtime programaticall

  - by Usman

  Suppose I have a VC++ project contains no of(say e.g 5) Source files(.cpp files),it will generate 5 .obj files(obj files corresponding to my .cpp's files not all kernel and OS layers including .obj files) e.g my project includes xyz_1.cpp,xyz_2.cpp,xyz_3.cpp,xyz_4.cpp,it will corresponds 4 respective .objs. By programtaically HOW CAN I TAKE AND GET THE NAMES OF THESE 4 .OBJ files at runtime(On run time I need to check how many obj files & names of those objs). REMEMBER I DON'T NEED ALL KERNEL AND OS LAYER .OBJS I ONLY NEED OBJS OF MY .CPPs. Regards Usman

• Add functions in gdb at runtime

  - by Michael Anderson

  I'm trying to debug some STL based C++ code in gdb. The code has something like int myfunc() { std::map<int,int> m; ... } Now in gdb, inside myfunc using "print m" gives something very ugly. What I've seen recommended is compiling something like void printmap( std::map<int,int> m ) { for( std::map<int,int>::iterator it = ... ) { printf("%d : %d", it->first, it->second ); } } Then in gdb doing (gdb) call printmap( m ) This seems like a good way to handle the issue... but can I put printmap into a seperate object file (or even dynamic library) that I then load into gdb at runtime rather than compiling it into my binary - as recompiling the binary every time I want to look at another STL variable is not fun .. while compiling and loading a single .o file for the print routine may be acceptable.

• Disable selected automated tests at runtime

  - by squig

  Is is posable to disable selected automated tests at runtime? I'm using VSTS and rhino mocks and have some intergation tests that require an external dependancy to be installed (MQ). Not all the developers on my team have this installed. Currently all the tests that require MQ inherit from a base class that checks if MQ is installed and if is not sets the test result to inconclusive. This works as it stops the tests from running, but marks the test run as unsuccseessful and can hide other failures. Any ideas?

• Crystal Reports and Report Viewer runtime question

  - by Spooky2010

  Using vs2008 c#. Howdy, Ive got an application where im trying to decide if i should use the Crystal reports or the Report viewer that comes with the visual studio install. My issue is that while it will run fine on my development machine, a lot of the machines the application will be deployed to in remote locations WONT have the runtime for either crystal reports or the report viewer installed. therefore if i build an application using either of these, and prevent user access to the reports only on the machines that do NOT have the runtimes, can the application run ok, or should i expect crazy errors on install and such Any advice appreciated.

• Reflection and changing a variables type at runtime?

  - by james-west

  Hi I'm trying to create an object Of a specific type. I've got the following code, but it fails because it can't cast the new table object to the one that is already defined. I need table to start of an IEnumerable type so I can't declare is an object. Public sub getTable(ByVal t as Type) Dim table As Table(Of Object) Dim tableType As Type = GetType(Table(Of )).MakeGenericType(t) table = FormatterServices.GetUninitializedObject(tableType) End sub So in short - is there a way of changing a variable type at runtime? (or a better way of doing what I'm doing) Thanks in advance. James

• add ms ajax accordion pane at runtime loses previous pane issue

  - by Chris Conway

  I have an AjaxControlToolkit accordion control that i'm trying to load panes at runtime. When I click a button inside a listview, it should add a new pane to the accordion control. Here is the code that adds the pane in the onitemcommand event within the listview var pane = new AccordionPane { ID = key }; pane.HeaderContainer.Controls.Add(new LiteralControl(label.Text)); pane.ContentContainer.Controls.Add(LoadControl("~/UserControls/Covers/" + e.CommandArgument + ".ascx")); accordion.Panes.Add(pane); And this will successfully show a webcontrol inside the accordion control. But when I click on another button in the listview, the accordion is reset and it only shows the new pane instead of appending a new pane. Is there any way to keep the previous pane visible across postbacks like this? By the way, each of the webcontrols that are loaded in the accordion have input fields that will need to be persisted across postbacks as well. thanks!

• Change My.Settings ConnectionString in runtime?

  - by Sultanen

  I have a ClickOnce deployment where i have a INI-settings file on the network file with "global" settings that is supposed to affect the program on all client computers. The problem i have is that i whant to have the Database connectionString stored in this INI file and have it read and stored in the My.Settings ConnectionString at program startup. How do i do this? The ConnectionString setting is Application scoped and therefore Read-Only, if i try to set it by My.Settings("ConnectionString") = "Source=server;Initial Catalog=database;Integrated Security=True" I get a runtime error: An error occurred creating the form. See Exception.InnerException for details. The error is: The type initializer for 'DB_lib.DB_LINQ' threw an exception. [EDIT] I got rid of the error by using the My.Settings("ConnectionString") = "Source=server;Initial Catalog=database;Integrated Security=True" in another place then the the eventtriggerd settingsLoaded method i created.. The problem is that even though the connectionstring semes to be the right, the program still connects to the "default" database that is typed in to the app.config file??

• Dynamic/runtime method creation (code generation) in Python

  - by Eli Bendersky

  Hello, I need to generate code for a method at runtime. It's important to be able to run arbitrary code and have a docstring. I came up with a solution combining exec and setattr, here's a dummy example: class Viking(object): def __init__(self): code = ''' def dynamo(self, arg): """ dynamo's a dynamic method! """ self.weight += 1 return arg * self.weight ''' self.weight = 50 d = {} exec code.strip() in d setattr(self.__class__, 'dynamo', d['dynamo']) if __name__ == "__main__": v = Viking() print v.dynamo(10) print v.dynamo(10) print v.dynamo.__doc__ Is there a better / safer / more idiomatic way of achieving the same result?

• Function with missing return value, behavior at runtime

  - by nabulke

  As expected, the compiler (VisualStudio 2008) will give a warning warning C4715: 'doSomethingWith' : not all control paths return a value when compiling the following code: int doSomethingWith(int value) { int returnValue = 3; bool condition = false; if(condition) // returnValue += value; // DOH return returnValue; } int main(int argc, char* argv[]) { int foo = 10; int result = doSomethingWith(foo); return 0; } But the program runs just fine. The return value of function doSomethingWith() is 0. Is is just undefined behavior, or is there a certain rule how the result value is created/computed at runtime. What happens with non-POD datatypes as return value?

Notice: Cost of the second query ist somewhat higher than for the first query. So the main question is: Why does the planner make the first decision, instead of the second? Also interesing: Via SET enable_seqscan TO false; i temp. disabled seq scans. Than the planner used indexes and hash joins, and the query still was slow. So the problem seems to be the hash join. Maybe someone can help in this confusing situation? thx, R.

• How to populating Ontology at runtime?

  - by Chan

  Hi, I have a configuration file with a lot of data like sensor locations, type, rules for activating devices etc. Basically related to a pervasive system. I plan to design an ontology for this domain. The doubt in my mind is how should I populate the ontology with the information in the configuration file, as the configuration files are going to change every now and then. Earlier I was planning to use XML, so I can just read the configuration file at runtime and create an XML as per the XSD. Do we use the same technique for Ontologies? If yes then what is the format of the populated ontology? Thanks Chan

• runtime loading of ValidateAntiForgeryToken Salt value

  - by p.campbell

  Consider an ASP.NET MVC application using the Salt parameter in the [ValidateAntiForgeryToken] directive. The scenario is such that the app will be used by many customers. It's not terribly desirable to have the Salt known at compile time. The current strategy is to locate the Salt value in the web.config. [ValidateAntiForgeryToken(Salt = Config.AppSalt)] //Config.AppSalt is a static property that reads the web.config. This leads to a compile-time exception suggesting that the Salt must be a const at compile time. An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type How can I modify the application to allow for a runtime loading of the Salt so that the app doesn't have to be re-salted and recompiled for each customer? Consider that the Salt won't change frequently, if at all, thereby removing the possibility of invalidating form

• Linq to SQL Where clause based on field selected at runtime

  - by robasaurus

  I'm trying to create a simple reusable search using LINQ to SQL. I pass in a list of words entered in a search box. The results are then filtered based on this criteria. private IQueryable<User> BasicNameSearch(IQueryable<User> usersToSearch, ICollection<string> individualWordsFromSearch) { return usersToSearch .Where(user => individualWordsFromSearch.Contains(user.Forename.ToLower()) || individualWordsFromSearch.Contains(user.Surname.ToLower())); } Now I want this same search functionality on a different datasource and want to dynamically select the fields to apply the search to. For instance instead of IQueryable of Users I may have an IQueryable of Cars and instead of firstname and surname the search goes off Make and Model. Basically the goal is to reuse the search logic by dynamically selecting what to search on at runtime.

• java runtime tracing library to replace system.out.println

  - by Grzegorz Oledzki

  Have you heard of any library which would allow me to set up a tracing for specific methods at runtime? Instead of adding (and removing) lots of System.out.println in my code (and having to re-compile and re-deploy) I would like to have a magic thing which would print out a line for each call of selected method without any change in the code. This would work without re-compiling, so some kind of JVM agent (or some non-standard JVM would be needed?). Sounds like a job for aspect programming? A typical scenario would be to start an application, configure the traced methods dynamically (in a separate file or similar) and then everytime a selected method is called a line with its name (and arguments) is printed out to System.out (or some log file). Naturally one could think of tens of additional features, but this basic set would be a great tool. BTW, I use Eclipse interactive debugger too, not only the System.out tracing technique, but both have some advantages and sometimes Eclipse is not enough.

  I wrote a simple javascript function for validating to fields in a aspx page function validate() { if (document.getElementById("<%=tbName.ClientID%>").value=="") { alert("Name Feild can not be blank"); document.getElementById("<%=tbName.ClientID%>").focus(); return false; } if (document.getElementById("<%=ddlBranch.ClientID%>").value=="SelectBranch") { alert("Branch Should Be Selected"); document.getElementById("<%=ddlBranch.ClientID%>").focus(); return false; } } Everything worked fine. Later I linked it to aspx page like a external js file. Now its giving error "Microsoft JScript runtime error: Object required". I'm unable to know where I went wrong.
