Changing Forms in VB

Kind of new to VB and have created an easy membership form.

I have now created two new forms but cannot get them too open.

I created a LogIn form which I would like to be opened first when the program is compiled.

 

oh its been awhile, but i believe its formname.show

 

Also, in the project settings, you can set the startup form. I would suggest you set your main form to the startup form, then in the Mainform.Load event show the Login form. If the credentials are verified, then continue. If not, try again, or shut down the application... However you want to handle it.
