multi forms in one desktop application

1. How do I define multi forms in the same winform app (C#) ?

I believe you're looking to make an MDI Application... here's a few links with some information/examples.

Thank
But I ment standard application that pressing on a button in one form causes
opening another form.
nor multi documents at the same time

Oh, sorry. You can just open another form... a Form object has a Show and a ShowDialog method. Show opens the form and lets you interact with other forms in that application. ShowDialog opens it as modal, which means you can't change focus to any other form until you close that one.

You just open it up in the button click event... here's a snippet.

...
private void button1_Click(object sender, EventArgs e)
{
  OtherForm otherForm = new OtherForm();
  otherForm.ShowDialog();

  if (otherForm.SomeStringProperty == "SomeStringValue")
    // Do something
}
...

That's a fairly brief example but hopefully you get the idea. Let me know if you have questions :)

Thanks alot
I understood what you said.
Now
First I opened a C# winform application
and implemented the form (Form1).
Then I did Project->add windows form
It opened relevant files. I implemeted them (Form2).

But, When I wanted to define an object of class "Form2"
in the handle of a button of form1, It did not recognize Form2.
Maybe there is a need to somehow do
some compilation or configuration connection between these two ???

Now, I added "using Form2NamesSpace; "

and it seems working . Thanks again
