Regards,
Hello every buddy, wishing all are coding greate(!) I have the following question:
Suppose following runtime invokation:
myInstance.getType().InvokeMember(aMember, BindingFlags.Public|BindingFlags.Instance|BindingFlags.GetField|BindingFlags.GetProperty, null, new object[] {});
If I execute this line while aMember is an inherited member property name of myInstance (not it's own) it works and returns the value.
Now if I call the same member and try to set the same member(inherited member property) it will throw an exception that 'Member not found'.
myInstance.getType().InvokeMember(aMember, BindingFlags.Public|BindingFlags.Instance|BindingFlags.SetField|BindingFlags.SetProperty, null, new object[] {newValueArray});
How can I fix this and set inherited properties of myInstance using Reflections?
Thank you

BindingFlags.SetField|BindingFlags.SetProperty
Get rid of that!
and this:
BindingFlags.GetField|BindingFlags.GetProperty
its not needed!
But better, use the GetProperty() method rather. Also ALWAYS check the return member info 1st, more than off its null , and then bang BIG BADA BOOM!

Thanks but:
If I get rid of 'BindingFlags.SetField|BindingFlags.SetProperty' then how can I set a property or field runtime using Reflection????

Ok, thread is over!
About my last question I got it now, using PropertyInfo.SetValue()... Thanks but:
I made a mistake posting this thread start. Type.InvokeMember(... BindingFlags.SetField|BindingFlags.SetProperty...) DOES return and set inherited types, the mistake was that I was tryong to set aMember into other type value than it's own, so Such 'aMember' with that target type could not be found and null would be returned.
Thank you and sorry for the mistake,

So: I have created ActiveX control inherits from the Control Class, as it written in Morgan Skinner's article. It was successfully registered in system, but when I have tried to add it in C# winform application, the mistake message was given:
"Converting the type library to a .Net assembly failed. Object reference not
set"
or if i try add .tlb file the mistake message was:
"Converting the type library to a .Net assembly failed. Type library was exported from a CLR assembly and can not re-imported as a CLR assembly"
What can i do? Что делать?

This post is rather puzzling. In the same sentence, ActiveX refers to something from the unmanaged world, and the Control class refers to something from the managed world.
Did you create an ActiveX control using an unmanaged compiler like VB6 or VC++6 ? If yes, then you can import it into the managed world by opening the toolbox window, right-click on it, select "Customize toolbox" (VS.NET 2002) or "Add or Remove Item" (VS.NET 2003), then click in the components tab, browse so you find the ActiveX dll, and finally drop it onto the form.
There are several cases however where the ActiveX import will fail. Most of the time, it just works.

I have created this control in С# in VS.Net 2002 => using a managed compiler

1) The C# compiler does not create ActiveX controls.
2) If you are in an unmanaged environment, it is possible to use a .NET user control like it was an ActiveX control, thanks to an undocumented technique, but I am not sure that's what you are talking about.
3) If you created that non-ActiveX user control with the C# compiler, then why don't you just include the .cs file in your other project? What is the tlb import for?

1. Thanks for lesson.
2. This control will be used with Delphi or CBuilder, that is why i need to do non-ActiveX control.
3.Do you know how can i do that.(use with Delphi)
4.(thanks to an undocumented technique) - what technique?
Thanks.

3) I would look around Delphi.NET and #Builder
4) Here[^] it is.

How can I maintain selected items in a bound list box control when it is bound to a datasource. What I currently do is add the item to a the underlying datasource which then automatically adds it to the listbox. I then use the setselected method of the list box to select the newly added item. This works great, but it unselects all my previous items that were selected. How do i get around this?
Thanks,
Ryan

Looking at the IL for the ListBox, this isn't possible. While both the SelectedIndecies and SelectedItems properties use a class that implements IList, IList.Add and related methods throw a NotSupportedException.
You'll have to derive your own ListBox class and create your own IList implementation that does implement those methods (and perform the necessary actions in the ListBox. If you have a program like .NET Reflector, you can see how the CheckedListBox derives from ListBox and do much the same thing.

For one, a service must be able to interact with the Desktop. There is an option for this in the SCM (service control manager). Also, the server must run as a user or other problems are likely to happen.
Why in the world are you trying to start notepad from a service, though? It's important to do things in the way they were intended. Services are programs that run without a user being logged in, or for global access by programs on your machine or other machines (like the Event Log service, for example).

starting notepad.exe was only an example.
the "interact with desktop" flag was the right answer.
i want to access a network-shares (as local system-service) to load notepad.exe from e.g. \\server1\share1\notepad.exe.
the guest-access is activated for that server and "Everybody" has the right to read that share, but my service cannot access this share. why?
