Linking forms together

Question

Could anyone help me and tell me how can i link two forms together. I've tried putting .Show() on the first form and then getting the new form in a new tab, but that's not what i need. What i actually mean if i press a button on the first form i need the second to start inside the first one. Actually to make 2 different forms into one.
For example if i press play on a simple game, the game starts instantly in the same dialog not a new one.

Thanks.

Thanks for the answer but i've tried tried this earlier and it's still not the result i've been searching for. When i do this i still get the window of the first form active i mean i get the second form as a part of the first one. The thing i'm looking for is actually the second form the gain the window of the first form. I hope you understand what i mean.

You need to use mdi forms assuming you have created two forms private void Form1_Load(object sender EventArgs e) { this.IsMdiContainer = true; } private void BttnOpenF2_Click(object sender EventArgs e) { Form F2 = new Form(); F2.MdiParent = this; F2.Show(); }
