I do have some classes that implement their own serialization/deserialization but I'm doing all of these without implementing system.runtime.serialization.ISerializable. so my question is what exactly is the benefit of using system.runtime.serialization.ISerializable ? in what example situation will we need to implement system.runtime.serialization.ISerializable?

View 10 Repliesi am studying and now working with Visual Studio 2008 Professional Edition. I am working on my project regarding "Serialization". I wanna to start my working with "System.Runtime.Serialization.Formatters.Binary" namespace because i am working on serialization project. I know by default IDE dosen't import it. So i went to add it in my project at "Add reference dialog" but i still unable to find out this namespace.
View 1 RepliesI'm experimenting with a plugin architecture for my company's internal business system. I have managed to read all .DLLs in a Plugin folder which implement a specific interface. What I am trying to figure out is the best method of communication between the "host" MDI parent application and forms that will be in the .DLLs which I intend to make MDI children.
Currently, I am returning just ToolStripMenuItem objects from the .DLLs to add to the MDI Parent. I've also tested that events wired in the .DLLs to the ToolStripMenuItems do propagate to the code in the .DLLs. I've also managed to return a Form object via the interface and open that form, as the Plugin folder is being "scanned".
However, I am not clear how I would make these forms MDI children. Also, any other forms living in the .DLLs will also have to be MDI children. I created a VS 2008 Addin project just to see what's going on, and it seems that the Addin accepts an Application object on which it adds to the ToolStripMenuItems and does other operations. The code to build the menu inside the .DLL. This is opposite of what I have done so far, where the MDI requests a ToolStripMenuItem from each .DLL and adds the returned object to its own menu.
Would designing my plugin architecture to accept an application object in the same manner the only way I could get forms to open as an MDI child? Am I asking for other, currently unknown to me, headaches by NOT passing in the application object to the .DLL?
I have a class called Tree, it has an arraylist called alTreeNodes. alTreeNodes is an arraylist of TreeNode class. Since I am using ISerializable Interface, I have to provide a specific constructor. I know how to write it for string parameters such as name_value, but how should i do with arraylist of object then? See "???" in the code blog before.

I have a vb .net application where the user can choose a directory into which an excel file is written.

I have two experimental web services. One is an asmx contained within a .net web application. The other is a WCF service library being invoked from the web application.The asmx basically does everything I need, but I think WCF would be better, except that it doesn't do anything as I would expect after fiddling with the asmx service.For example, the same method behaves differently in each:
' ASMX
<WebMethod(BufferResponse:=True, EnableSession:=False)>
Function Test(aObject as Object) as Object
' object will have been successfully serializaed into a dictionary

I need to generate a class at runtime similar to System.Resources where you can add a resource eg 'picture.bmp' and it immediatelly is accessible as 'System.Resources.picture.bmp'. I presume I need to generate XLM or/and XLSD at design time and then deserialise at runtime but I cant find a reference on how to do this. Specially without knowing the generic class in advance (as 'System.Resources' doesnt know all the resources in advance).

I am a *** programmer and cannot make sense of the error message I'm getting. I wrote a program and it runs fine on my development machine and also on other machines with Visual Studio installed. However, when I run it on any other machines, I get the message below.All of my other programs that I write run fine on these other machines; so I know this problem must be due to some control that's unique to this new program. But I can't make much sense of the error report

We have a small visual basic 6.0 application with an Access DB that we would like to migrate to modern code and architecture. I am not technical, but I am believe this would be something like a .net framework with a SQL Server DB.What I am wondering about, is there any way to covert this code to a modern language/architecture? If so, what is the easist modern language to migrate to?

View 15 RepliesWhen trying to determine the Architecture of an OS, I ran across IntPtr.From reading the documentation, I saw this: Quote:The IntPtr type is designed to be an integer whose size is platform-specific. That is, an instance of this type is expected to be 32-bits on 32-bit hardware and operating systems, and 64-bits on 64-bit hardware and operating systems.
Since the size of IntPtr is intended to be the size of the architecture, would it be feasible to test the size and determine the OS by that? Or is there a better way?
I was thinking there might also be a way via WMI, but I don't want to use that for compatibility reason.
Is there a way to programatically determine if the OS Architecture is 32-bit or 64 -bit?

I need to write an app that that will iterate over our database, and perform various anaylsis on each record. In order to do this (partially for the learning exercise in creating plugin support) I want to use a Plugin model.
Currently, I have a simple Interface in my main app, which plugins can Implement. My app then loads all DLL's in a folder looking for ones implementing the Interface.
As you can see in the pseudo-code below, I have to keep performing a loop through all loaded plugins calling the process methods.
