hmmm... a bit strange... have a look on the forms msdn pages about it:
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.minimizebox.aspx
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.aspx

Maybe the formborderstyle must be changed because it's not working with all of them.

Found something like this (vb.net by the way but shouldn't be hard to translate though.
Me.FormBorderStyle =
System.Windows.Forms.FormBorderStyle.None
Me.MaximizeBox = False
Me.MinimizeBox = False
Me.ControlBox = False
Me.WindowState =
System.Windows.Forms.FormWindowState.Maximized

Or maybe you could also try it using api calls directly:
EnableMenuItem(ChildForm.Handle, SC_MAXIMIZE, MF_DISABLED);

http://msdn.microsoft.com/en-us/library/ms647636(VS.85).aspx
In the form class's constructor, simply add the code:

this.ControlBox=false;

Or

You can use the below code while creating a new instance of form:

MyForm formObject = new MyForm();
formObject.ControlBox=false;
System.Windows.Forms.Application.Run(formObject);

Any reason that you are answering a 7-year-old question? Do you think that he is still waiting for an answer all these years later?

Please refrain from answering old tombstoned questions and instead focus your energy on answering questions that are current where people really need help!
