Hi all experts,

I have created 1 form ( frmmain) and 1 folder and in that folder i create 3 forms ( form1,form2,form3 ). in frmmain form, i have some buttons to click and show some info in form1,form2,form3 in folder. i try to declare form1 f=new form1() but i don't see form1 or form2 or form3. i can see only frmmain.

Does anybody know how i can declare and open form1,form2,form3 inside folder?

Thanks

Have you added the other forms to your solution in Visual Studio?

What does it mean, "form in folder", "folder creates a form"? A form is just a form, and a folder is just the metaphor concept representing a directory...
And which form do you mean, a Web form, or

System.Windows.Forms.Form?

Try this.
Add a button to frmMain, and handle it's Click event:

C#

private void button1_Click(object sender, EventArgs e)
    {
    Form1 f1 = new Form1();
    f1.ShowDialog();
    Form2 f2 = new Form2();
    f2.ShowDialog();
    }

That will create a new instance of Form1, and display it. When the Form1 is closed, the frmMain will continue and a new Form2 will be displayed.
Then try this:

C#

private void button1_Click(object sender, EventArgs e)
    {
    Form1 f1 = new Form1();
    f1.Show();
    Form2 f2 = new Form2();
    f2.Show();
    }

That will show a new instance of Form1 and Form2 - but it will not wait until they close, frmMain will continue to work.

Sour Sdey, Tony,

I think people here will understand you better if you use the words "solution, or project," instead of "folder." The word "folder" has the specific meaning of a file-folder in Windows.

In Windows Forms, when you create a Solution/Application: that automatically creates a main Form, titled "Form1," which will be shown automatically when the application is run.

At design-time, in your development environment, like Visual Studio, you can create-and-add other Forms, UserControls, Classes, etc., to your solution.

Forms you declare at design-time must be made visible in code, using, as OriginalGriff shows you how to do in his answer here, 'Show, or 'ShowDialog.

The standard behavior (default) of a Windows Forms Application is that when the Main Form is closed, all other Forms that are active are automatically closed with it.

With Visual Studio, a Solution may have several Projects. And, a Project may be a Class Library (code only), or an executable Application. You tell Visual Studio which Project to start when you run the solution by setting the StartUp Property.
