I am loading a .NET application using the ICLRRuntimeHost::ExecuteInDefaultAppDomain method which starts the application up fine. However, the application is using Log4Net with which it should output an info message after starting up, but it never does. It works fine when opening it up normally though, so it must be something with the CLR Hosting environment that makes it unable to function properly, I just don't know what exactly.
Here is the code that does the logging:
using System;
using System.Windows.Forms;
using log4net;
namespace TestApplication
{
public partial class MainForm : Form
{
private static readonly ILog log = LogManager.GetLogger
(MethodBase.GetCurrentMethod().DeclaringType);
public MainForm()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
log.Info("Application has started");
}
}
}

I have a winform app, I completed with business model and update function. But when I learn about security .Net, I found that almost impossible to anti crack/hacking with obfuscation.
So I want move 99.99% source code to cloud. But I've not found any doc that useful for making it.
Can I do my idea as below:
using ....;
namespace myApp
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public GetSourceClass()
{
// Here i want get all source code, include all class and all
// variables from server.Is it possible?
}
private void Form1_Load(object sender, EventArgs e)
{
GetSourceClass();
}
I m using Unis 3.1.1 with Virdi Ac7000 and gathered all employees fingerprints on one device and when trying to distribute users data all over other devices all emp data is transfered very well except the fingerprint
I tried on Access DB and Oracle and the same problem
is there any conf. has to be done or this is a bug in UNIS
I downloaded the VIRDI SDK from
https://drive.google.com/folderview?id=0B06Dxl8hzdKDZllHYlloU3lZbUk&usp=sharing
and tried to run the server within visual studio but also gave me 1002 error and didn't start although the example UCSAPI_Demo.exe in runs very well
using System.Windows.Forms;
using UCSAPICOMLib;
using UCBioBSPCOMLib;
namespace UCSAPI_DemoCSharp
{
public partial class test : Form
{
public UCSAPICOMLib.UCSAPI ucsAPI;
public UCSAPI m_Api = new UCSAPI();
public test()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
m_Api.ServerStart(999, 9870);
MessageBox.Show(m_Api.ErrorCode.ToString("X4"));
}
private void test_Load(object sender, EventArgs e)
{
}
}
}
This error is related to the dlls, your application is not accessing it well.
Pls, try putting all the VIRDI dlls, in the same folder of your application.
I have an issue related to running CodedUITests from a Windows Form. (it works in the CodedUITestProject with Test-Explorer).
This is my CodedUITest's structure :
[CodedUITest]
public class DBTest
{
#region Static Fields
public static CSVReader csvReader;
#endregion
#region Fields
public string logFileName;
public string timer = String.Empty;
public TestRead testRead;
public UploadResults uploadResults;
private DateTime testStart;
#endregion
[ClassInitialize]
public static void MyTestInitialize(TestContext test)
{
csvReader = new CSVReader();
csvReader.LoadTestValues("steam.csv");
}
[TestInitialize]
public void testInit()
{
testStart = DateTime.Now;
}
[TestMethod(), TestCategory("Reflection"), TestCategory("DataDriven"), DataSource("Microsoft.VisualStudio.TestTools.DataSource.CSV", #"|DataDirectory|\CSV's\steam.csv", "steam#csv", DataAccessMethod.Sequential), DeploymentItem(#"..\..\CSV's\steam.csv")]
public void steamAccess()
{
testRead = new TestRead();
SteamMap a = new SteamMap();
testRead.Read(a, TestContext);
}
[TestCleanup]
public void TestCleanup()
{
uploadResults = new UploadResults();
//timer for each test ( in seconds )
double diffSecs = (DateTime.Now - testStart).TotalSeconds;
uploadResults.TestUpload(testRead.TestResults, csvReader.DataTable, diffSecs,TestContext);
}
public TestContext TestContext
{
get
{
return testContextInstance;
}
set
{
testContextInstance = value;
}
}
private TestContext testContextInstance;
}
This runs perfectly from VS's Test Explorer, testContextInitialize variable gets initialized.
In the same Solution I've added a second project, a simple Windows Form application, added a reference to my DLL ( from References) which runs the following code :
Playback.Initialize();
DBTest a = new DBTest();
a.steamAccess();
Playback.Cleanup();
NullReferenceException occurs, my testContex is null when I run my test from outside it's assembly.
I need some help in this matter, Thanks
Edit 1:
Test Class :
using System;
using System.Collections.Generic;
using System.Text.RegularExpressions;
using System.Windows.Input;
using System.Windows.Forms;

public class.....
Edit 2:
Temporary workaround until I find the cause of this error :
From my Windows Form I launch a MSTest with few required parameters and most of the what-methods-to-run logic will come from my database. I already did this few months ago but I scraped it because it's an additional performance overhead to use a tool such as MsTest within a launcher such as mine.
For anyone interested, there's a file located within VS's installation directory, it's called VsDevCmd.bat, I load this .bat within a hidden-in-background cmd with few additional commands ( mstest, testcontainer, test). This works but as I said I have no other plausible ideas.
There may also be a lack of referenced libraries within my Form ? Maybe something, a .dll that initialized the testenvironment and the testContext variable.
I wrote this because there may be others seeking the same result.
To clarify on my comment: internal is default in C#, so declaring something as abstract is like declaring it as "internal abstract".
For InternalsVisibleTo, you must make the library project visible to the test project, not the other way around:
[assembly:InternalsVisibleTo("MyTestProject")]
I've been watching some tuts on how to create a C# Windows Service; all good but no one says how to make te service run, at the end of installation, a specific file from installation folder(in my case hidden.vbs)(my app has 2 project: the service itself and the setup).
After the install of the setup, the service starts PROJECT_NAME.exe and PROJECT_NAME.svhost.exe
Tell me please if you need any other code in order to help me...
Here is my Program.cs
using System.ComponentModel;
using System.Configuration.Install;
using System.Linq;
using System.ServiceProcess;
namespace PROJECT_NAME
{
[RunInstaller(true)]
public partial class ProjectInstaller : System.Configuration.Install.Installer
{
public ProjectInstaller()
{
InitializeComponent();
}
private void serviceInstaller1_AfterInstall(object sender, InstallEventArgs e)
{
new ServiceController(serviceInstaller1.ServiceName).Start();
}
}
}
Service1.cs
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Linq;
using System.ServiceProcess;
using System.Text;
namespace PROJECT_NAME
{
public partial class Service1 : ServiceBase
{
public Service1()
{
InitializeComponent();
}
public void OnDebug()
{
OnStart(null);
}
protected override void OnStart(string[] args)
{
System.IO.File.Create(AppDomain.CurrentDomain.BaseDirectory + "OnStart.txt");
}
protected override void OnStop()
{
System.IO.File.Create(AppDomain.CurrentDomain.BaseDirectory + "OnStart.txt");
}
}
}
Also, here is a pic of my Solution Explorer http://i.imgur.com/wbqUGOc.png ; please tell me how or where should I import the files I need the service to run.
It's my first time in C#, I'm not willing to understand it now, but to make this service because I will need it in my work..
Your script can do one of several things to start a service:
Issue the net start console command to launch a service (e.g. net start "My Service Name")
OR
Programmaticaly, call the StartService API.
I’m pretty new to programming, so bear with me if my question isn’t specific enough. Right now I’m trying to make a simple Client Logon to my server. So the server App knows which users are connected. When a client connects I want an event to fire on the server that update the userlist. But it doesn’t and I can’t figure out why. Hope you can help.
In the codes I have removed how the users should be displayed in the serverApp. Right now I just need the event to work.
In my Service Library:
INetworkService contract:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
namespace NetworkLib
{
[ServiceContract]
public interface INetworkService
{
[OperationContract]
void Logon(UserInfo userInfo);
[OperationContract]
void Logout();
}
}
NetworkService Class:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
namespace NetworkLib
{
public class NetworkService : INetworkService
{
public event EventHandler UserListChanged;
public void Logon(UserInfo userInfo)
{
OnUserListChanged();
}
public void Logout()
{
OnUserListChanged();
}
private void OnUserListChanged()
{
var handler = UserListChanged;
if (handler != null)
{
handler(this, EventArgs.Empty);
}
}
}
}
UserInfo Class:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.Serialization;
namespace NetworkLib
{
[DataContract]
public class UserInfo
{
[DataMember]
public string Name;
}
}
In my ServerApp (WPF):
using System.ServiceModel;
using NetworkLib;
namespace ServerApp
{
public partial class MainWindow : Window
{
NetworkService networkService;
public MainWindow()
{
InitializeComponent();
ServiceHost host = new ServiceHost(typeof(NetworkService));
host.Open();
networkService = new NetworkService();
networkService.UserListChanged += networkService_UserListChanged;
}
private void networkService_UserListChanged(object sender, EventArgs e)
{
MessageBox.Show("It Works!");
}
}
}
In my ClientApp (WPF): (Have made a Service Reference to the Server)
namespace ClientApp
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void button1_Click(object sender, RoutedEventArgs e)
{
ServiceReference.NetworkServiceClient proxy = new ServiceReference.NetworkServiceClient();
ServiceReference.UserInfo userInfo = new ServiceReference.UserInfo();
userInfo.Name = "Test";
proxy.Logon(userInfo);
}
}
}
You subscribe to event of other NetworkService instance than ServiceHost instantiates. In your case every time you make request to server, new NetworkService instance is created. Place the following attribute above NetworkService class:
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
Then subscribe to event:
var serviceInstance = (NetworkService)host.SingletonInstance;
serviceInstance.UserListChanged += networkService_UserListChanged;
When creating your ServiceHost, you should provide NetworkService instance instead of typeof(NetworkService)
ServiceHost host = new ServiceHost(networkService);
You need to initialize it first, of course.
I didnt look in great detail but overall your code looks ok. It is sometimes useful in this situation to run 2 instances of VisualStudio - one for server in debug and one for client in debug. If you put a break point in client button1_Click code in VS thats debugging client, and a break point in NetworkServices.Logout in VS thats debugging server you will be able to step from client to server code and see easily whats going wrong where.
Why do you need an event model here? Why not just handle your "event" directly in NetworkService.Logout(). Does pushing this off to an event and then having to wire that event (which as ilya.dofofeev correctly points out is not on the same object) provide any real benefit?
