Hello!
I have one solution file that consist of three project.
One project that build the exe file called A
One project that build a user control dll. Here we have a class called B
One project that build a class library dll. Here we have a class called C
We have one dependency and that is from the user control to the class
library because
in the constructor for class B in the user control we have a call to
instansiate class C in the class library dll.
public B()
{
InitializeCompo nent();
Last.C last = new Last.C();
last.foo();
}
In the project that create the exe file I have a project reference to the
user control.
In the project that create the user control I have a project reference to
the class library.
When I add the user control to the Toolbox I use the obj/debug directory to
select the user control dll.
Now to my problem when I try to drag the user control from the toolbox into
a form I get the following error "An exception occured while trying to
create an instance of WindowsControlL ibrary.B. The execption was "?"."
Is this kind of a bug that cause this problem.
Is it possible to solve this kind of problem in some way.
I have even rebuild the user control dll and the class library dll but it
doesn't matter.
//Tony
I just wonder what is the requirement about the dll and its version on the
dll
I noticed that when I get error
4  1679 
Hi Tony,
The problem doesn't stem from the fact that the User Control assembly
references the assembly it depends on, and that the executable references
the User Control assembly. I know that for a fact because I have done this
many times. What I don't know is what caused the error.

Hi!
When I have this kind of problem what is the solution?
If I put the class library in the GAC that is called by the user control
would that solve my problem?
Do you think that this could be a bug because you have experienced this
kind of problem yourself.
I see that you are Microsoft MVP so do you think it's possible to send a
mail to microsoft telling them about my problem.

You misunderstood me, Tony. I have never had this problem. I have
successfully done the same thing you're trying to do without any problems,
and no, I didn't use the GAC.

Hello!
When I'm in design mode and drag the user control from the toolbox into
a form that exist in the project that build the exe file which search path
is used to locate the class library dll.
Many thanks
