Borderless form Mobile API

Copy the API code to the form code structure function, reference the namespace, Delegate MouseDown event (Lee brainstorming Lxc)

     //The form Shadow API, placed above the structure function, modifies the structure function to        Const intCs_dropshadow =0x20000; Const intGcl_style = (- -); [DllImport ("user32.dll", CharSet =CharSet.Auto)] Public Static extern intSetclasslong (INTPTR hwnd,intNIndex,intDwnewlong); [DllImport ("user32.dll", CharSet =CharSet.Auto)] Public Static extern intGetclasslong (INTPTR hwnd,intNIndex);  PublicForm1 () {InitializeComponent (); Setclasslong ( This.

form Shadow API

Copy the API code above the structure function and modify the structure function to

API-General Function interface

Make a form with no borders as follows

One or five border form move

Copy the API code to the form code structure function below, reference the namespace, delegate the MouseDown event

 PublicForm1 () {InitializeComponent (); }        //Form Mobile API[DllImport ("user32.dll")]         Public Static extern BOOLreleasecapture (); [DllImport ("user32.dll")]         Public Static extern BOOLSendMessage (INTPTR hwnd,intWmsg,intWParam,intIparam);  Public Const intWm_syscommand =0x0112;  Public Const intSc_move =0xf010;  Public Const intHtcaption =0x0002; [DllImport ("User32")]        Private Static extern intSendMessage (INTPTR hwnd,intWmsg,intWParam, IntPtr lParam); Private Const intWm_setredraw =0xB; Private voidForm1_mousedown (Objectsender, MouseEventArgs e) {            if( This.
