  • The action or event has been blocked by Disabled Mode

    - by mattruma
    I am using Microsoft Access 2007 to move and massage some data between two SQL Servers. Yesterday everything was working correctly, I was able to run queries, update data, and delete data. Today I opened up the Access database to finish my data migration and am now receiving the following message when I try to run some update queries: The action or event has been blocked by Disabled Mode. Any ideas what this is talking about?

  • A compiler for automata theory

    - by saadtaame
    I'm designing a programming language for automata theory. My goal is to allow programmers to use machines (DFA, NFA, etc...) as units in expressions. I'm confused whether the language should be compiled, interpreted, or jit-compiled! My intuition is that compilation is a good choice, for some operations might take too much time (converting NFA's to equivalent DFA's can be expensive). Translating to x86 seems good. There is one issue however: I want the user to be able to plot machines. Any ideas?

  • iphone in-app purchases not working after rejection

    - by Joey
    I recently had an issue with my in-app purchases, so had them rejected. I found that upon creating new ones and approving them, I am getting no products back from my SKProductsRequest. Do new in-app purchases require some delay to be updated on their servers or is there some common reason that they stop working when an app is rejected?

  • How to generate custom JSESSIONID, based on some hash of user's data?

    - by Shaman
    Is it possible to override Tomcat's embedded generator of JSESSIONID, to be able to create custom values of this cookie, based on user's login? Why do I need this: I have a load balancer with "sticky sessions", configured to route requests with the same JSESSIONID to the same server, and I want to prevent situation, when same user can start two different sessions on different servers.

  • Using WebSockets in a C# Web Application?

    - by sixones
    I know its possible to use WebSockets within C# using a console application running along side the web application but Im wondering if its possible to use the requests on the C# web application to create the WebSockets. I've been looking through ASP.Net and Im starting to think it wont be possible unless I use straight up C# and create my own HTTP server and then use the same socket object to generate Web Sockets (similar to the way Node.js and Socket.IO work). Any thoughts on ways to include WebSockets on a C# web application without having multiple servers / projects?

  • How to retrieve a bigint from a database and place it into an Int64 in SSIS

    - by b0fh
    I ran into this problem a couple years back and am hoping there has been a fix and I just don't know about it. I am using an 'Execute SQL Task' in the Control Flow of an SSIS package to retrieve a 'bigint' ID value. The task is supposed to place this in an Int64 SSIS variable but I getting the error: "The type of the value being assigned to variable "User::AuditID" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object." When I brought this to MS' attention a couple years back they stated that I had to 'work around' this by placing the bigint into an SSIS object variable and then converting the value to Int64 as needed. Does anyone know if this has been fixed or do I still have to 'work around' this mess? edit: Server Stats Product: Microsoft SQL Server Enterprise Edition Operating System: Microsoft Windows NT 5.2 (3790) Platform: NT INTEL X86 Version: 9.00.1399.06

  • How to handle ordering of @Rule's when they are dependant on eachother

    - by Lennart Schedin
    I use embedded servers that run inside Junit test cases. Sometimes these servers require a working directory (for example the Apache Directory server). The new @Rule in Junit 4.7 can handle these cases. The TemporaryFolder-Rule can create a temporary directory. A custom ExternalResource-Rule can be created for server. But how do I handle if I want to pass the result from one rule into another: import static org.junit.Assert.assertEquals; import java.io.*; import org.junit.*; import org.junit.rules.*; public class FolderRuleOrderingTest { @Rule public TemporaryFolder folder = new TemporaryFolder(); @Rule public MyNumberServer server = new MyNumberServer(folder); @Test public void testMyNumberServer() throws IOException { server.storeNumber(10); assertEquals(10, server.getNumber()); } /** Simple server that can store one number */ private static class MyNumberServer extends ExternalResource { private TemporaryFolder folder; /** The actual datafile where the number are stored */ private File dataFile; public MyNumberServer(TemporaryFolder folder) { this.folder = folder; } @Override protected void before() throws Throwable { if (folder.getRoot() == null) { throw new RuntimeException("TemporaryFolder not properly initialized"); } //All server data are stored to a working folder File workingFolder = folder.newFolder("my-work-folder"); dataFile = new File(workingFolder, "datafile"); } public void storeNumber(int number) throws IOException { dataFile.createNewFile(); DataOutputStream out = new DataOutputStream(new FileOutputStream(dataFile)); out.writeInt(number); } public int getNumber() throws IOException { DataInputStream in = new DataInputStream(new FileInputStream(dataFile)); return in.readInt(); } } } In this code the folder is sent as a parameter into the server so that the server can create a working directory to store data. However this does not work because Junit processes the rules in reverse order as they are defined in the file. The TemporaryFolder Rule will not be executed before the server Rule. Thus the root-folder in TempraryFolder will be null, resulting that any files are created relative to the current working directory. If I reverse the order of the attributes in my class I get a compile error because I cannot reference a variable before it is defined. I'm using Junit 4.8.1 (because the ordering of rules was fixed a bit from the 4.7 release)

  • State server in webfarm scenario?

    - by Curtis White
    This is a fairly basic question about state server but assume there are 2 servers behind a load balancer. How do I configure the session state server? So, I have machine1 and machine2. I would assume that I would need to install the state server on 1 machine only and then use the internal IP to refer to that machine. Is this correct? As oppose too, I would not install state server on both machines.

  • C/C++ - Convert 24-bit signed integer to float

    - by e-t172
    I'm programming in C++. I need to convert a 24-bit signed integer (stored in a 3-byte array) to float (normalizing to [-1.0,1.0]). The platform is MSVC++ on x86 (which means the input is little-endian). I tried this: float convert(const unsigned char* src) { int i = src[2]; i = (i << 8) | src[1]; i = (i << 8) | src[0]; const float Q = 2.0 / ((1 << 24) - 1.0); return (i + 0.5) * Q; } I'm not entirely sure, but it seems the results I'm getting from this code are incorrect. So, is my code wrong and if so, why?

  • What perl function to use?

    - by user301087
    I'm setting something up to SSH out to several servers in 'batches'. I basically want to maintain 5 connections at a time, and when one finishes open up another (following an array of server IPs). I'm wondering for something like this should I be using fork()? If so, what logic can I use to ensure that the I maintain 5 children at a time?

  • How to create a local Windows-based service bus outside of Azure, similar to Redis with automatic fail-over?

    - by ElHaix
    We are implementing a service/message-bus feature in our SignalR application and have been looking at Redis, with automatic fail-over using Redis Sentiel. We would like to maintain our own servers and have read SignalR powered by Service Bus. Since this is a Winddows Azure implementation, how can I accomplish this in our internal network with VM's with automatic fail-over similar to the Redis solution discussed above?

  • .Net OutOfMemory on Server but not Desktop

    - by Jörg Battermann
    Is it possible that the .Net framework behaves differently when it comes to garbage collection / memory limitations on server environments? I am running explicitly x86 compiled apps on a 64bit server machine with 32gbs of physical ram and I am running out of memory (SystemOutOfMemoryException) even though nothing but that particular app is running and the server/all other apps utilize 520mb total.. but I cannot reproduce that behaviour on my own (client win7) machine. Now I know that the app -is- memory intensive, but why is it causing problems on the server and not on the client?

  • how to invoke a webservice from one container in another container in glassfish

    - by vinny
    I have webservices deployed on two containers in two separate servers A and B. A webMethod in 'Server A' needs to invoke a webmethod in 'Server B'. I have created a client stub for Sever B. Im trying to make 'Server A' use this client stub and talk to Server B. I get an exception while trying to instantiate the port object specifically at : service.getABCBeanPort(); (using JAX-WS library) Is my approach correct? Is there any better way of invoking a webservice on a remote server?
