See more:

I get a build error.
CS0246 Type or Namespace name 'FrmNewmonth' could not be found.
I have added the form and its code to the project, which shows up under references.

I am not sure where or how to declare FrmNewMonth.cs

I am pretty new to C# so I ask some basic qusitions.

What I have tried:

C#

//this.Hide();
//this.Hide();
FrmNewMonth pantryForm = new FrmNewMonth();
pantryForm.Show();
//Application.EnableVisualStyles();
//Application.SetCompatibleTextRenderingDefault(false);
//Application.Run(new frmFoodPantry());

And I get a build error.
CS0246 Type or Namespace name 'FrmNewmonth' could not be found.
I have added the form and its code to the project, which shows up under references.

Look at the error message: your class is named FrmNewMonth with a capital 'M' for month, not FrmNewmonth. So find the line with the incorrect spelling.

It's telling you you don't have a class (a Form is a class!) called "FrmNewMonth" defined anywhere.

Oh, and C# is case-sensitive. "frmNewMonth" is not the same as "FrmNewMonth".

Yeah, I found out it was case-sensitive the hard way.

How do I declare it as a class when I have already brought the code into the main project?

I know this is a newbie question, and I should know it.

I have no idea what you're talking about with the code.

To rename a form, you click on the form itself in the designer (NOT a control on it!) and in the Properties window, there's a (Name) property. Change that and it changes the name of the form. You have to use that name in your code when referring to that class.

The designer writes the code for the form (class) itself.

That worked; I did a copy-paste from the form name and had to add a using statement. So it works now.

If it is part of the same project and namespace, you should not need a using statement.
