At the moment i'm creating a remote object instance by:
Dim serverURI = String.Format("{0}://localhost:{1}/{2}", IPC.Protocol, IPC.port, IPC.Channel_name)
Me.Server = CType(Activator.GetObject(GetType(RemotebaleServiceCommands), serverURI), RemotebaleServiceCommands)
I need to pass some constructor arguments to RemotebaleServiceCommands call.
I have some code that runs within a multithreaded class.Basically i create many threads which contain instance of this class.Within this class i create an object to either a vb6 or .net dll using reflection, then i call a method within that object. The object that gets called can be different every time.But for some reason even through i have multiple threads going when i get to the Activator.CreateInstance it is no longer multithreaded. I want to catch the error returned and put it in a log.
If UCase(pRow("TypeVB6").ToString()) = "TRUE" Then
classType = Type.GetTypeFromProgID(ClasstoInstantiate, True)
Else

how might I redo this method with Activator.CreateInstance
Public Overridable Function setCreditType() As CreditType

I have a type (Human) and I want to know if I could do System.Activator.CreateInstance(Of Human)(). So basically I want to check if Human has a public parameterless constructor / or a public constructor with optional parameters that make it possible to call New Human without giving any arguments.Is it possible to check beforehand if ystem.Activator.CreateInstance(Of T) will fail? (I mean other than wrapping the statement System.Activator.CreateInstance(Of Human)() in a Try Catch of course..)I've tried this but it doesn't work:
Option Strict On : Option Explicit On
Module Test

I'm trying to create a new instance of a Dictionary(Of String, ??) based on a ItemType variable I have. How do I construct the DictType so that I can use Activator to create an Instance of the type I'm after?
Dim ItemType As Type ' Data type of dictionary value
Dim DictType As Type = ???? ' Dictionary(of String, ItemType)
Dim NewDict = Activator.CreateInstance(DictType)
How does the Windows activator know whether to activate an executable in 32 or 64 bit mode?
View 11 RepliesI'm my program always fails at the same line:
objUser = GetObject("LDAP://CN=" & strUser & "," & ADPath)
If I reduce the code down to just this:
objUser = GetObject(), I still get this exception:
"Cannot create ActiveX component."
After googling this for about 18 hours, I found that it could be because of a permissions issue. I am a local administrator on the PC, so I believe that takes care of permissions. Secondly, I discovered that the dll file might not be registered. I tried to use the following command to register the dll file I think is being used:
regsvr32 "c:windowssystem32wldap32.dll"
It says the following:
Error - The module "C:windowssystem32wldap32.dll" was loaded but the entry-point DllUnregisterServer was not found. Make sure that "c:windowssystem32wldap32.dll" is a valid DLL or OCX file and then try again.So no matter what I try to do, I keep getting this unhandled exception error that says that it cannot create the activex component. What do I need to do to be able to use this getObject() command? Is the problem with LDAP? What activeX or DLL file is failing if even just running the getObject command gives an exception?
Trying to run this piece of code and i get the error cannot create activex component.works fine on windows 2003,works fine on windows 2008 if user is logged in with admin access.

I'm writing a class-library in VB.Net and one of the subs that are being called from the application which is using my library has more or less the following syntax:
Public Sub LoadDict(ByVal PhoneticType As String, ByVal strDict As String)
where PhoneticType can be phonSoundex, phonDoubleMetaphone or noPhonetic
I want to give the application-developer a possibility to select the PhoneticType from a list when writing the call of above sub (I think it's called attribute-arguments). This would make it easier for the developer since spelling-errors can be avoided and which will avoid errors when using the library. I think it's all about attributes but I haven't managed to get it to work despite trying.
I've created custom buttons in a .dll and they work fine, so I thought I'd have a go at creating my own sort of listbox to replace the standard one in my applications. It's basically a panel with a few labels and a button (eliminating the need to select an item in standard listbox then click a seperate button). I want to add these panels to a panel on a form, at run-time, based on rows in a db.
If I try adding any arguments in the New() section of the class file it won't let me use the panel in my toolbox. Is there a way to pass arguments to custom controls, I need a new custom panel for each row in a db so need to pass an id to it to specify records; or even load the records in my application and create a new panel for each record, using info passed to it to fill in the labels on it. Or can I create the panel at run-time and refer to labels within the custom controls, setting their .text properties that way?
I am new to visual basic 2008. I can't seem to grasp arguments in a function. Can anyone give me a simple explanation of what they are, how they work, and why we need them?
