[Tutorial] Move a borderless form

[Mr.Zunz]

Heyho, here's an example of what i used in my application to move a borderless form.

Put this pointer and a bool outside any event:

private Point LastCursorPosition;
private bool IsMouseDown;

Example

        private Point LastCursorPosition;
        private bool IsMouseDown;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            // Do something
        }

Put this in your Form1_MouseDown event.

this.IsMouseDown = true;
this.LastCursorPosition = new Point(e.X, e.Y);

Put this in your Form1_MouseUp event.

this.IsMouseDown = false;

put this in your Form1_MouseMove event

if (this.IsMouseDown == true)
            {
                //Move the form
                this.Location = new Point(this.Left - (this.LastCursorPosition.X - e.X), this.Top - (this.LastCursorPosition.Y - e.Y));

                //Redraw the form//
                this.Invalidate();
            }

That's it! it's simple

I'm pretty sure I saw this on CodeProject or something. It's a cool idea, and idk if you took it from there. Kind of common sense, but w/e. I might put it to use sometime.

You can do it like this too:

using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using System.Threading;
using Magic;
using System.Diagnostics;
using BlueBox;

namespace ConsoleGUI
{
    public partial class frmMain : Form
    {
        #region Form Dragging API Support

        //The SendMessage function sends a message to a window or windows. 
        [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
        static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, int wParam, int lParam);

        //ReleaseCapture releases a mouse capture
        [DllImportAttribute("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
        public static extern bool ReleaseCapture();

        #endregion

        public frmMain()
        {
            InitializeComponent();
        }

        #region Moving the form around

        private void textBox_console_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                ReleaseCapture();
                SendMessage(Handle, 0xA1, 0x2, 0);
            }
        }

        private void frmMain_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                ReleaseCapture();
                SendMessage(Handle, 0xa1, 0x2, 0);
            }
        }

        #endregion

       
    }
}

if (this.IsMouseDown == true)

8 characters not needed: " == true".

pointer

what pointer

[Robske]

WPF users can do the following:

Add this line to your XAML:

<Window x:Class="PCynder.WindowHome"  MouseLeftButtonDown="WindowHome_MouseLeftButtonDown">
        Window components, resources, templates etc come here
</window>

Then add the following to your code:

/// <summary>
/// Allow Dragging of a borderless window.
/// </summary>
private void WindowHome_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
      if (e.LeftButton == MouseButtonState.Pressed)
                this.DragMove();
}

Now try doing it in JAVALOL

Yeah I did copypasta it from my own source, and im 95% sure i got it form codeproject so, Yup. I thought I just wanted to share it on here. I'm not taking credits for it tho. :wave:
