visual basic error BC30456 'Form1' is not a member of 'WindowsApplication1'

Question

Hello I am trying to do an exercise and keep getting this error when compiling.

Visual Basic error BC30456 'Form1' is not a member of 'WindowsApplication1'

I'm not sure how to fix it.

Below is my code:

Public Class frmCentsConverter
    Private Sub txtAmount_TextChanged(sender As Object, e As EventArgs) Handles txtAmount.TextChanged
        If IsNumeric(txtAmount.Text) Then
            Dim NumberofCents As Integer

            NumberofCents = CInt(txtAmount.Text)
            lblDollars.Text = CStr(NumberofCents \ 100)
            lblCents.Text = CStr(NumberofCents Mod 100)
        End If
    End Sub

    Private Sub lblTitle_Click(sender As Object, e As EventArgs) Handles lblTitle.Click

    End Sub
End Class

Answer 1

If you have renamed the startup form1 it is likely you also have to change the Startup form setting. You can find this setting to open 'My Project' in the 'Solution Explorer'. Select the Application section, change the 'startup form' as appropriate.

Hope this will help, Harrie

Answer 2

To set the startup form in Windows Forms

1. In Solution Explorer, right-click the project and choose Properties.
2. The Project property page opens with the Application properties displayed.
3. Choose the form you want as the startup form from the Startup Object drop-down list.

I got this information from this website:

I can confirm this works on Visual Studio 2015 as well.
