How to achieve a captionless bordered Aero window?

I know how I can remove the border of my form, but I simply want to remove the caption. Googling for P/Invokes didn't give me much results, so I'm wondering, how can I achieve such a result?

Solution

  • Coming from unmanaged development, I'd P/Invoke {Get/Set}WindowLong, etc. etc. -- which was my initial response -- but there's a managed way to deal with this.

    You'll want to override the CreateParams property in your form, removing the bordering style and adding the thick frame style, as such:

    ...
const UInt32 WS_THICKFRAME = 0x40000;
const UInt32 WS_BORDER = 0x800000;
...

protected override CreateParams CreateParams
{
  get
  {
    CreateParams p = base.CreateParams;
    p.Style |= WS_THICKFRAME;
    p.Style &= ~WS_BORDER;

    return p;
  }
}
