"please check wethere the dll is valid assambly or a com component"
is it possible to import the dll as unmanaged dll?
thank You

stancrm wrote: SHDocVw.dll
do not have windowStateChange event
but if i refer "microsoft.mshtml.dll" i get windowStateChange event. how to go about?
and i take for granted that it is not possible to add all the dll in .net (dll are diffrent 1.com dll 2.net dll and 3 system dll) is it correct?

Although Microsoft chose to have the same extension for these files, there are different "flavors" of dll files.
1. Native dll that has exported funtions - Use DllImport attribute to use functions in these dlls
2. COM dll (aka ActiveX dll) - Use 'add reference' dialog to add reference to these dlls - The VS IDE silently creates a RCW (Runtime Callable Wrapper), that is essentially a .NET Assembly that makes it easy to use your COM dll. This is what has happend in your case (Interop.Dsofile.dll is the RCW for dsofile.dll - you need both files for your app to run).
3. Managed dll (aka .NET Assembly) - These are created by .NET compilers and can be used directly from .NET clients. They can also be used by COM clients using CCW (COM Callable Wrappers).
Uhhh!!! Quite complex, isn't it ?

Hi there... I need some help with putting data in a ListView from a list of objects (List<object>).
It's a rather complex list I have, because the objects in my list itself contains list of objects in many levels.
I'll try to simplify the list:
Let's say we have the following list of objects:
List<x> -> where X contains "A", "B", "C" and "List<y>"
List<y> -> contains "D", "E", "F" and "List<z>"
List<z> -> contains "G", "H", "I".
The list is placed in one project called Control, in class controller.cs
In another project called View, in class myForm.cs I have a ListView.
View has reference to Control, so myForm.cs will be "calling" controller.cs
Now to my problem: I would like to bind (object- or data-bind) my ListView to the List<x>, so that the ListView will list the "A's", "E's" and "I's" for all X-objects in the list.
Furthermore, if the user change data in the ListView, it should also change in the List<x>.
AND, if the user add a new row in the ListView with new data (A, E and I) the List<x> should contain a new X-object with the "A", "E" and "I" data.
For this example the other properties could just be empty (null) or whatever.
I've searched the net for a solution, without luck. All I find is something like binding datatables to ListView.
Someone here who can help me with this?
Just for the record, I have very little experience with bindings, so be gentle

The Listview does not support databinding natively although there are a number of work around examples[^].
Your design sucks if you are allowing the user to edit the data in a list control (Listview or grid). The management of the control and the list and the events associated with editing is a PITA.
I suggest you pop a dialog for the user to edit into and deal with the dialogresult to reload the list.

You are right. I'm using DataGridView now.... much better
But I ran into a new problem
On a form I have a ComboBox binded with List<x>, so that the ComboBox views the "Name" of the X-objects. Works fine
But for the selected X-object i ComboBox, I want to view the X's Y-objects (List<y>) in a DataGridView.
But I can't find a way to bind the ComboBox and DataGridView together.

Socket will be the simplest method of all.

Socket won't know any difference between image and data. You can have your own protocol and add some header information to the client side application to know that the data coming is a image file. The application can then display the image and name accordingly.
