Hello,
 
          Environment : Visual C++4.2b , Window NT 4.0
 
         I have created an OLE control through Appwizard. While creating
I have
selected YES for license validation. I am able to create OCX succes
fully but when I try to insert this control into OLE test container it
says Unable to Insert specified Control. How do I give license key. Is
there any technical notes on this.

Make sure the license file is available when the control is inserted.
If it isn't in the same directory as the control's executable, there
will be trouble.

You could figure out exactly what's going on by using the debugger.
Visual C++ comes with a very, very powerful debugger.  You could set
the executable image for your debugging session to be TSTCON32.EXE,
and put a breakpoint on the licensing member functions within  your 
control.  You'd be albe to trace through the code and see _exactly_
what fails right as it's happening!
