I tried going to Project > Properties, and then the Application tab, startup object, but the only choice is "Calculations.Program", and none of my forms are shown in there...

Thanks in advance.

Open the Calaculations.Program file. Should be named Program.cs. You'll see the startup form in there. You can then change it to whatever.

The template for a WinForms application was changed in 2.0

Previously, a default form was created under the name 'Form1.cs' which contained, among other things, a static Main method. Somewhere in the project properties, you set 'Form1' as your startup object. That means that the entry point is Form1.Main. This method is the your program's entry point.

In 2.0 this was changed. While you still get a template 'Form1' class, the entry point has moved in to the 'Program' class by default. It contains only one method -- Main. You cannot set the startup object to Form1 because it does not contain a static Main method with the right signature.

The solution is simple. The default Main method does most of its work in one method call. It calls Application.Run and passes it a Form object (by default expressed as 'new Form1()' ) Application.Run starts the message loop, and returns when the provided Form is closed. When Run returns, Main is over, and the program exits. Just change 'new Whatever()' to the desired startup form.

If your using Visual Studio 2005 you can right click on something like properties in the Document Tree and then select the form you want form the drop-down menu.

Hi,

How to set the Startup form in C#

When the application starts up, the first form to be displayed, has to be specified in the Project properties window. In C#, in the ‘Startup object’ drop down list box, the MenuForm option will not be displayed. So, to set the ‘Startup object’, select the class that contains Main( ) in the Project Properties dialog box. To do this, create a class, name it finstart, and type the following:

(Toggle Plain Text)

using System;
using System.Collections.Generic;
using System.Text;
namespace FinCsharpProject
{    class FinStart
    {	static void Main()
        {		
          	System.Windows.Forms.Application.Run(new MenuForm());
        }
    }
}

Now, in the Startup object drop down list box of the properties dialog box, FinStart classs will be displayed. Choose this option. When we run the application, the MenuForm will be displayed at startup.

You don't post an intro, you drag the lake for a dead thread, then you hijack that thread to ask your (totally unrelated, I might add) question? Don't be surprised if nobody helps.
