How to load child forms in tab control in a MDI form

[milisecond]

hello , i wana load child forms in a tab control in mdi form when user opens a chil form

This is the code in VB .NET, just add a panel to each tabcontrol, and replace childform with the instance of the form you want to display.

 	 Panel1.Controls.Clear()
        childForm.FormBorderStyle = FormBorderStyle.None
        childForm.MaximizeBox = False
        childForm.MinimizeBox = False
        childForm.ControlBox = False
        Me.IsMdiContainer = True
        childForm.MdiParent = Me
        childForm.Dock = DockStyle.Fill
        childForm.Parent = Panel1
         childForm.Show()
        Panel1.Update()

Don't use MDI, just add the Forms as you would a control.
Be sure to set TopLevel=False on all the child windows.

Here's the C# version of what I use:
[code=C#]
this.IsMdiConta iner = true;

MyCustomForm myForm = new MyCustomForm();
myForm.TopLevel = false;
myForm.Parent = this;
myForm.Dock = DockStyle.Fill;
myForm.FormBord erStyle = FormBorderStyle .None;
TheTabPageToAdd To.Controls.Add (myForm);
myForm.Show();
