[RESOLVED] Change buttonname on a second form

[xavier73]

I want to change a button name of form1 and I want to do this from form2.
When i click on a button on form2 i want to change it.
I'm using form1.button1.text="Name"
But i get the message:
'Button1' is not a member of System.Windows.Forms.Mainmenu

How can i do this??
