Activator.Creat eInstance Problems

Huw
I have written a small procedure that opens a dialog that
I pass it.

Sub MyOpen(txtForm as string)

Dim frm As Object
Dim frmType As Type
frmType = Type.GetType(tx tForm)
frm = Activator.Creat eInstance(frmTy pe)
frmType.InvokeM ember("ShowDial og",
BindingFlags.In vokeMethod, Nothing, frm, Nothing)

End Sub

This works fine when I pass it form names that exist in
the current .exe file e.g. MyOpen("MyApp.M yForm")

However what I really want to do is open forms that are
contained in a sperate windows .dll file i.e. MyOpen
("MyDll.MyForm" ), but it does not seem to work... Will it
work if I supply the full public token id as the string?
If so how do I obtain the full public token id of a form
in a seperate .dll file?

Thanks in advance

Use the static method Assembly.Load(a ssemblyDisplayN ame) to load the
assembly that contains the form. Using that assembly reference, make a call
to GetType().
Sub MyOpen(txtForm as string)

--->
Dim asmbly = Assembly.Load(" AssemblyDisplay Name")
frmType = asmbly.GetType( txtForm)
--->

End Sub

Thanks,

Huw,
In addition to Vijaya Krishna P's comments.

You can include the assemble name in the string you pass to Type.GetType.

MyOpen("MyDll.M yForm, MyDll")

Which presumes that you named the assembly & namespace where the MyForm is
the same name (which is the default).

Hope this helps
Jay

Hi, I need to design a method that creates and returns a large array of objects. The problem is that the *type* of object to create isn't know until runtime. As a result, a parameter of type "Type" must be passed in: IMyInterface CreateObjects(Type type,int numberOfObjects); Internally this method will call Activator.CreateInstance() to create the objects. Here's my question: Is there a significant performance penalty

Hello, I'm loading a Class from Assemly DLL using Activator.CreateInstance. That loaded Class is executed in a worker Thread with no loop. What actually happends when class is loaded using Activator.CreateInstance? If I create same class using Activator.CreateInstance many times will there be multiple instances of that same class created by Activator.CreateInstance?
