It is not clear what your problem is. Could you try to explain what happens and how it is different to what you expected to happen?

Solution 1

I'm not entirely sure what you are expecting to happen here, but your code in both cases will only create one instance of each form - it specifically doesn't create a new instance ever again.

So I'm guessing that what happens is:
Create EmpForm as result of menu click.
Use EmpForm.
Use closes EmpForm
User clicks menu again, no new EmpForm is displayed.

And similarly for your Party form.

If that's the case, then when you create your form, you need to add a handler for the FormClosed event and when that event is fired, you set f2 (or f3 as relevant) to Nothing.
That way the second time the menu item is clicked, the code will be able to create a new instance again.

If it isn't that, then you need to explain in better detail exactly what you are trying to achieve and what problem it is giving you.
