Errors trying to link a form from a different project to my main form of another project in same solution in VB. NET

I'm trying to see if I was able to link a menu item (For sake of examples: DisplayProject) in my main Form1 to a Form1 in another project (Project name: PopUpMessage) that is in the same solution.

I already added it from the reference option, so I am able to use the object in my main Form1.

I thought maybe by declaring the following it would work within this menuitem from MenuStrip. I wrapped this in a "try/catch" by the way which is why I get that pop up windows:

        Try
           PopUpMessage.Form1.ActiveForm.ShowDialog()
        Catch ex As Exception
           MessageBox.Show(ex.Message)
        End Try

I am declaring this in DisplayMessage project Form1 menustrip item. However I get the error:

As daring as I am, I decided to do the following:

    Try
       PopUpMessage.Form1.ActiveForm.Visible = False
       PopUpMessage.Form1.ActiveForm.ShowDialog()
    Catch ex As Exception
       MessageBox.Show(ex.Message)
    End Try

Then I go the following error: Second Error Message

Anyone has an idea what can be done? I'm kinda new to this type of methods used in VB .NET.

Thank you in advance!

You've found the right answer, but to explain what you saw: Form.ActiveForm is a Shared Property and returns the current foreground form, if there is one, not specific to your Class.

Then, either ShowDialog correctly complains you're trying to redisplay an already visible form or you're trying to execute a method on Nothing.

Already found the way to do it. For future reference it's: 

Dim PopUpMessage As New PopUpMessage.Form1
    Try
        PopUpMessage.Show()
    Catch ex As Exception
        MessageBox.Show(ex.Message)
    End Try

That was all...
