• Majid.vagheeian GetReferencedAssemblies

  Hi, I'm trying to get all referenced assemblies, however GetReferencedAssemblies returns only those referenced assemblies that are already loaded. How can I find the unloaded referenced assemblies as well Thanks, Tom GetReferencedAssemblies should return all references, whether or not they are loaded. If that's not what you're seeing, please post code to reproduce the problem. Are the missing references actually used by the assembly Keep in mind that the C# compiler will exclude references to unused assemblies. So the set of references in your C# project may be larger than the references in the compiled assembly. No, the referenced assemblies are not used by the executing assembly. Is ther ...Show All

• Petknep Non-serializable type in a remoting environment

  I have the type System.Security.Principal.SecurityIdentifier used within an object which I'm passing to another environment using .NET remoting. Because the inner object of type SecurityIdentifier is not serializable or marshalled by ref, I'm getting a SerializationException. Type 'System.Security.Principal.SecurityIdentifier' in Assembly 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable. Is there a way around this (other than using a different type) Perhaps I should clone the object on the foreign environment I'm open to suggestions. If the type is not serializable, it can't be serialized. There is no workaround except building your own ...Show All

• SurreDeth Problems with IEnumerator in VB6 (COM Interop)

  Hi! I'm trying to expose a collection from my C# library to a COM client. This collection should be iterated using the for each construct in Visual Basic 6. Unfortunately this won't work as expected. The IEnumerator interface is actually acquired and in the fer each statement iterate objects. But these object don't have any properties and cannot be cast into my original object's interface. Here is the sample C# code: using System; using System.Collections; using System.Runtime.InteropServices; namespace TestEnum { [Guid("00D26E58-FCE6-41fd-B5B4-3A694C1E9D7F")] [InterfaceType(ComInterfaceType.InterfaceIsDual)] [ComVisible(true)] public interface ITestCollection { [DispId(-4)] IEnumerator GetEnumerator(); ITest GetAt(in ...Show All

• bilalso Instrumentation problems using latest Jan 2006 version of Enterprise Library

  Has anyone ever tried instrumenting a component using InstrumentationListener and InstrumentationProvider from the latest Enterprise Library I am following a sample code from the documentation but it fails during run-time when I try to raise OnDbConnect event from the code below. The error that I get is "Object reference not set to an instance of an object". I am sure it is an easy fix but I cannot seem to find what is wrong. ObjectBuilder is supposed to link an OnDbConnect event from the InstrumentationProvider with the function ConnectObserved() from the InstrumentationListener, but that is clearly not happening :-( Here is the code: public partial class Form1 : Form { public Form1() { InitializeComponent ...Show All

• Bryan Stone multithreading with networking

  Hi, I have an application that uses a socket dll (classical dll). This dll is written in Winsock vb6, and it connects to server over tcp and send and receive data. I have two identical threads in my program that create instance of a class in the DLL to use it to send data over tcp. These two connect to same Ip, port, and does same tasks, the only difference is that the first one reads top half of a db table and other one reads bottom half. Now, I see that these two take turns in sending data. When first one starts, other stops and when other starts, the first one stops. Any ideas why they behave such a way I have 1 million records, and I created two threads to make it faster. Thanks in advance, Noorul ...Show All
