c# - Changing cursor shape to have the copy cursor shape -

i know when doing drag-drop can like

private void form_dragover(object sender, drageventargs e) {     e.effect = dragdropeffects.copy; } 

to make cursor have plus image meaning copy. wondering if can when not doing drag-drop (for example when user clicks specific place cursor changes style until user clicks somewhere else). tried using cursor = cursors.<style> not contain this. ideas ?

this quite difficult unless want display wait cursor. special case, handled application.usewaitcursor property. problem every control affects cursor shape, selected cursor property. textbox example insist on changing shape i-bar.

you ahead wanting between 2 clicks. trickery possible in case, can capture mouse when button clicked cursor shape solely controlled button. hack required when user clicks mouse again, click go same button , not whatever control clicked. needs fixed synthesizing click. sample code gets done:

    bool customcursorshown;      private void button1_mouseup(object sender, mouseeventargs e) {         if (button1.displayrectangle.contains(e.location)) {             this.begininvoke(new action(() => {                 customcursorshown = true;                 button1.cursor = cursors.help;   // change cursor want                 button1.capture = true;             }));         }     }      private void button1_mousedown(object sender, mouseeventargs e) {         if (customcursorshown) {             var pos = this.pointtoclient(button1.pointtoscreen(e.location));             var ctl = this.getchildatpoint(pos);             if (ctl != null && e.button == mousebuttons.left) {                 // may want alter if special action required                 // i'm synthesizing mousedown event here...                 pos = ctl.pointtoclient(button1.pointtoscreen(e.location));                 var lp = new intptr(pos.x + pos.y << 16);                 // note: taking shortcut on wparam here...                 postmessage(ctl.handle, 0x201, (intptr)1, lp);             }                          }         button1.capture = false;     }      private void button1_mousecapturechanged(object sender, eventargs e) {         if (!button1.capture) {             customcursorshown = false;             button1.cursor = cursors.default;         }     }      [system.runtime.interopservices.dllimport("user32.dll")]     private extern static intptr postmessage(intptr hwnd, int msg, intptr wp, intptr lp);
