Form1

Hi all,

I'm very new to this Visual Basic thing. In class we were shown how to choose properties of a form that we have renamed to frmHomework or something similar.

For some reason I do not have a drop down selection from tools to do the same at home. I'm sure it's a version difference but...how can I change the name of the current form to something other then Form1 without getting compile errors.

(name) is Form1 but when changed I get this error.

There were build errors.
'Sub Main' was not found in example1.Form1'.

To me it's simply is saying hey it's not the same thing so make sure you rename it in the right places. but the trouble i'm having is i'm having trouble finding all the right places.

Not sure if this will help or not but here's the code.

Public Class frm3_3_1
Inherits System.Windows.Forms.Form

#Region " Windows Form Designer generated code "

Public Sub New()
MyBase.New()

'This call is required by the Windows Form Designer.
InitializeComponent()

'Add any initialization after the InitializeComponent() call

End Sub

'Form overrides dispose to clean up the component list.
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub

Help???

When I get that message (through absent mindedness mainly in my case) there is usually a small dialog box that pops up with a list of candidates for objects that have the sub main().

I usually double click the new form name from the list. Is this the list that you are referring to?

What version of VB are you using? I'm on Standard 2003 at the moment (FW1.1)

Try this:

Project...Properties...Common Properties...General...Startup Object

Set it to the form name.
