    - by schrodinger's code
    my config file below: very strange, i have spent a day to find out where i am wrong, but still not working, it still not log anything in the database,but i can output them using RollingFileAppender. Also, the store procedure WriteLog is working well.(I have tested it using sql server studio). I have tried to change the connectionType but not working. Unfortunately I dont have sql server 2000/2005 to test, my log4net version should be the latest one: log4net 1.2.10.

  • C++ vs. C++/CLI: Const qualification of virtual function parameters

    - by James McNellis
    [All of the following was tested using Visual Studio 2008 SP1] In C++, const qualification of parameter types does not affect the type of a function (8.3.5/3: "Any cv-qualifier modifying a parameter type is deleted") So, for example, in the following class hierarchy, Derived::Foo overrides Base::Foo: struct Base { virtual void Foo(const int i) { } }; struct Derived : Base { virtual void Foo(int i) { } }; Consider a similar hierarchy in C++/CLI: ref class Base abstract { public: virtual void Foo(const int) = 0; }; ref class Derived : public Base { public: virtual void Foo(int i) override { } }; If I then create an instance of Derived: int main(array<System::String ^> ^args) { Derived^ d = gcnew Derived; } it compiles without errors or warnings. When I run it, it throws the following exception and then terminates: An unhandled exception of type 'System.TypeLoadException' occurred in ClrVirtualTest.exe Additional information: Method 'Foo' in type 'Derived'...does not have an implementation. That exception seems to indicate that the const qualification of the parameter does affect the type of the function in C++/CLI (or, at least it affects overriding in some way). However, if I comment out the line containing the definition of Derived::Foo, the compiler reports the following error (on the line in main where the instance of Derived is instantiated): error C2259: 'Derived': cannot instantiate abstract class If I add the const qualifier to the parameter of Derived::Foo or remove the const qualifier from the parameter of Base::Foo, it compiles and runs with no errors. I would think that if the const qualification of the parameter affects the type of the function, I should get this error if the const qualification of the parameter in the derived class virtual function does not match the const qualification of the parameter in the base class virtual function. If I change the type of Derived::Foo's parameter from an int to a double, I get the following warning (in addition to the aforementioned error, C2259): warning C4490: 'override': incorrect use of override specifier; 'Derived::Foo' does not match a base ref class method So, my question is, effectively, does the const qualification of function parameters affect the type of the function in C++/CLI? If so, why does this compile and why are there no errors or warnings? If not, why is an exception thrown?

  • DynamicMethod NullReferenceException

    - by Jeff
    Can anyone tell me what's wrong with my IL code here? IL_0000: nop IL_0001: ldarg.1 IL_0002: isinst MyXmlWriter IL_0007: stloc.0 IL_0008: ldloc.0 IL_0009: ldarg.2 IL_000a: ldind.ref IL_000b: unbox.any TestEnum IL_0010: ldfld Int64 value__/FastSerializer.TestEnum IL_0015: callvirt Void WriteValue(Int64)/System.Xml.XmlWriter IL_001a: nop IL_001b: ret I'm going crazy here, since I've written a test app which does the same thing as above, but in C#, and in reflector the IL code from that looks just like my DynamicMethod's IL code above (except my test C# app uses a TestStruct with a public field instead of the private value field on the enum above, but I have skipVisibility set to true)... I get a NullReferenceException. My DynamicMethod's signature is: public delegate void DynamicWrite(IMyXmlWriter writer, ref object value, MyContract contract); And I'm definitely not passing in anything null. Thanks in advance!

  • How can I make my Perl Jabber bot an event-driven program?

    - by TheGNUGuy
    I'm trying to make a Jabber bot and I am having trouble keeping it running while waiting for messages. How do I get my script to continuously run?

  • Recovering text files in terminal using grep on Mac OS X Snow Leopard

    - by littlejim84
    I foolishly removed some source code from my Mac OS X Snow Leopard machine with rm -rf when doing something with buildout. I want to try and recover these files again. I haven't touched the system since to try and seek an answer. I found this article and it seems like the grep method is the way to go, but when running it on my machine I'm getting 'Resource busy' when trying to run it on the disk. I'm using this command: sudo grep -a -B1000 -A1000 'video_output' /dev/disk0s2 > file.txt Where 'dev/disk0s2' is what came up when I ran df. I get this when running: grep: /dev/disk0s2: Resource busy I'm not an expert with this stuff, I'm trying my best. Please can anyone help me further? I'm on the verge of losing two days of source code work! Thank you

  • Assignments failing

    - by Andrei Krotkov
    I'm debugging part of a large project in Visual Studio 2005, and stepping through the code line by line. int speed = this->values.speed; int ref = this->values.ref_speed; After stepping past the first line, values.speed has a value of 61, but for some reason, speed is getting assigned the value 58. After the second line, values.ref_speed has a value of 58, but ref gets assigned the value 30. When paused, you can see that the original values are in fact 61 and 58 respectively, but the values getting stored are different. What is causing this behaviour?

  • C# problem with two threads and hardware access

    - by mack369
    I'm creating an application which communicates with the device via FT2232H USB/RS232 converter. For communication I'm using FTD2XX_NET.dll library from FTDI website. I'm using two threads: first thread continuously reads data from the device the second thread is the main thread of the Windows Form Application I've got a problem when I'm trying to write any data to the device while the receiver's thread is running. The main thread simply hangs up on ftdiDevice.Write function. I tried to synchronize both threads so that only one thread can use Read/Write function at the same time, but it didn't help. Below code responsible for the communication. Note that following functions are methods of FtdiPort class. Receiver's thread private void receiverLoop() { if (this.DataReceivedHandler == null) { throw new BackendException("dataReceived delegate is not set"); } FTDI.FT_STATUS ftStatus = FTDI.FT_STATUS.FT_OK; byte[] readBytes = new byte[this.ReadBufferSize]; while (true) { lock (FtdiPort.threadLocker) { UInt32 numBytesRead = 0; ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead); if (ftStatus == FTDI.FT_STATUS.FT_OK) { this.DataReceivedHandler(readBytes, numBytesRead); } else { Trace.WriteLine(String.Format("Couldn't read data from ftdi: status {0}", ftStatus)); Thread.Sleep(10); } } Thread.Sleep(this.RXThreadDelay); } } Write function called from main thread public void Write(byte[] data, int length) { if (this.IsOpened) { uint i = 0; lock (FtdiPort.threadLocker) { this.ftdiDevice.Write(data, length, ref i); } Thread.Sleep(1); if (i != (int)length) { throw new BackendException("Couldnt send all data"); } } else { throw new BackendException("Port is closed"); } } Object used to synchronize two threads static Object threadLocker = new Object(); Method that starts the receiver's thread private void startReceiver() { if (this.DataReceivedHandler == null) { return; } if (this.IsOpened == false) { throw new BackendException("Trying to start listening for raw data while disconnected"); } this.receiverThread = new Thread(this.receiverLoop); //this.receiverThread.Name = "protocolListener"; this.receiverThread.IsBackground = true; this.receiverThread.Start(); } The ftdiDevice.Write function doesn't hang up if I comment following line: ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead);

  • How can Nagios handle non-threshold based plugins?

    - by FliesLikeABrick
    I am writing a Nagios plugin to monitor trends of a certain storage resource utilization (e.g. gradual increases are fine, but an instantaneous/sudden increase or decrease in resource usage may indicate a problem). For what it's worth, it is reviewing the last N entries in an RRD file generated by a custom cacti data source/templates. What is the "right" way to handle Nagios notification config/implementation for this? The problem is that it the plugin would exit as warning/critical for one polling period, but in the next it would be fine (or 3 polling periods later, if I look at 3 polling periods worth of data). I guess the question is: should I just write it in such a way that it will alert for X polling periods, or should I find a way to write it such that manual intervention is required for it to clear (such as logging into the monitoring server or hitting a URL to run a script that submits a passive result)? Your input is appreciated, and if you have any tips for how to implement the latter I'm open to them (I can think of a few ways to possibly implement it)

Disconnect all previous connections to the server or shared resource and try again." Troubleshooting I've Done Start Run cmd net use * /DELETE Start Manage Windows Credentials Deleted all credentials I still receive the same error until I reboot my machine. After I reboot, it works fine. However, I am able to log into the admin share if I hit it by it's IP address. QUESTION My question is, is there somewhere else I should be looking for cached user credentials? Thanks, Brian

  • Why is the destructor called when the CPython garbage collector is disabled?

    - by Frederik
    I'm trying to understand the internals of the CPython garbage collector, specifically when the destructor is called. So far, the behavior is intuitive, but the following case trips me up: Disable the GC. Create an object, then remove a reference to it. The object is destroyed and the __del__ method is called. I thought this would only happen if the garbage collector was enabled. Can someone explain why this happens? Is there a way to defer calling the destructor? import gc import unittest _destroyed = False class MyClass(object): def __del__(self): global _destroyed _destroyed = True class GarbageCollectionTest(unittest.TestCase): def testExplicitGarbageCollection(self): gc.disable() ref = MyClass() ref = None # The next test fails. # The object is automatically destroyed even with the collector turned off. self.assertFalse(_destroyed) gc.collect() self.assertTrue(_destroyed) if __name__=='__main__': unittest.main() Disclaimer: this code is not meant for production -- I've already noted that this is very implementation-specific and does not work on Jython.

  • Struts2 JPA Validation error how to forward to action and not lose ActionErrors messages ?

    - by Sebastien Dionne
    I'm using Hibernate validator 4.1 to validate my entity. I have a dashboard that I can access from the action : viewDashboard. In my action, I load 2 List in my acion like this. public String execute() throws Exception { listDocteur = service.listDocteur(); listUser = service.listUser(); return SUCCESS; } In the DashBoard, I have a submit that can add a User. <action name="saveUser" class="com.test.action.CreateUserAction" method="execute" <interceptor-ref name="mybasicStackWithValidation" </interceptor-ref <result name="input"/WEB-INF/jsp/viewDashboard.jsp</result <result name="success" type="redirectAction"viewDashboard</result </action if I submit invalid value, I'll see the error messages, but I'll lose my 2 Lists. If I have a type="redirectAction".. I lose the error messages. in Struts 1, I would forward to the action viewDashboard.do without a redirect and that will works.. but How to do that in Struts2 ?
