Windows forms question...

Question

I have a couple of questions for you all. 1. Is it possible to set the formborderstyle to none and still be able to drag the form around the screen. It seems that when ever I don't have a border on my form it is locked on the screen whee the form initially loads. Is this the way it always works? 2. can someone point me to some samples of creating a docable window? I would like to be able to dock a window to the top or bottom of the screen and also allow for auto-hide type functionality. Any assistance would be greatly appreciated. Thank you Bob

Though I don't have much experience in WinForms I vaguely remember there are something like the WinForms Dock control  which seems to be able to support dock window auto-hide featured function. Don't know if this piece of information would be helpful or not. However hope you find out your way to success.

Yes that is normal behavior. That's why you need to programmatically control the size and position or allow the user to drag it some other way. Here's one way that works. private Boolean mousedown = false; private Point mousestart; private void Form1_MouseDown(object sender System.Windows.Forms.MouseEventArgs e) { mousedown = true; mousestart = new Point(e.X e.Y); } private void Form1_MouseMove(object sender System.Windows.Forms.MouseEventArgs e) { if (mousedown == true) { this.Left = this.Left + (e.X - mousestart.X); this.Top = this.Top + (e.Y - mousestart.Y); } } private void Form1_MouseUp(object sender System.Windows.Forms.MouseEventArgs e) { mousedown = false; } To dock a window is pretty easy. Just set the form's .Left and .Top properties to the desired position bearing in mind the width or height of the form. To hide it just animatically change the size and position of the form simultaneously until it disappears. This example sticks the form in the upper-left corner of the screen. private void button10_Click(object sender System.EventArgs e) { int right = (Screen.PrimaryScreen.Bounds.Right - Screen.PrimaryScreen.Bounds.Left); this.Left = right - this.Width; this.Top = 0; } If you set the borderstyle to none the user can't drag it away. If you set the borderstyle to NOT none set the Locked property to TRUE to prevent moving or resizing. You may combine the dragging code above with a toggling Locked property to allow a snap to border behavior like Winamp does. Very cool effect.
