Transperent window

[NaNg15241]

Hello, I want to do a Windows Form that doesn't have a close (X) and minimize (_) buttons as it normally have, it wan't it costum, or an image that I'll supply, OR that there will not be a control box AND no border, and inside the form I will supply an image with everything, but if I'll choose this, how will I be able to drag the window? In anyways, the image inside is rounded and I don't know how to make the edges to be transperent, and not white\any-other-color. (If someone know what is Steam, I'm talking about something like that.) Thanks in advance... NaNg

A very easy way to do it is to override WndProc on your form, handle WM_NCHITTEST, call the default, and if it returns HTCLIENT, change it for HTCAPTION. You'll be able to drag the form around by clicking on the client area. I'm at home right now, but if you need help on that (or sample code), reply to this post and I'll show you some sample code that I have at the office. Those constants (WM_NCHITTEST, HTCLIENT, HTCAPTION) can be looked up in Windows.h. -- LuisR

This code will create a form that can be moved by dragging from the client area:

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
 
        const int WM_NCHITTEST = 0x84;
 
        const int HTCLIENT = 1;
        const int HTCAPTION = 2;
        const int HTSIZE = 4;
        const int HTBOTTOMLEFT = 16;
 
        protected override void WndProc(ref Message m)
        {
            base.WndProc(ref m);
 
            if (m.Msg == WM_NCHITTEST)
            {
                if (m.Result == (IntPtr) HTCLIENT)
                    m.Result = (IntPtr) HTCAPTION;
            }
        }
    }

I hope it helps! -- LuisR
