.net - How to detect a double-click outside of vb.net form -

-

setup environment:

i'm using visual studio 2010 , writing code in vb.net (with .net framework 4).


my goal:

  1. use shell("c:\myprogram.exe", appwinstyle.normalfocus) open new application
  2. with new application open active window, recognize when user double clicks

if active window vb.net form, it's simple recognize double click event so:

private sub button2_doubleclick(......) handles button2.doubleclick

end sub


this code works recognize single left click:

  • this form1.vb

    public class form1      private withevents mousedetector mousedetector      private sub form1_load(byval sender object, byval e system.eventargs) handles me.load          mousedetector = new mousedetector      end sub      private sub mousedetector_mouseleftbuttonclick(byval sender object, byval e system.windows.forms.mouseeventargs) handles mousedetector.mouseleftbuttonclick          'left click occurred         msgbox("left click")      end sub  end class


  • here's enum in mousedetector.vb

    private enum mousemessages     wm_leftbuttondown = 513     wm_leftbuttonup = 514     wm_leftdblclick = 515     wm_rightbuttondown = 516     wm_rightbuttonup = 517     wm_rightdblclick = 518 end enum


  • and here's function in mousedetector.vb recognizes single click

    private function mousehookproc(byval ncode integer, byval wparam integer, byval lparam intptr) integer         if ncode < 0             return callnexthookex(mousehookid, ncode, wparam, lparam)         end if         dim mousedata mousehookstruct = marshal.ptrtostructure(lparam, gettype(mousehookstruct))         select case wparam              case mousemessages.wm_leftbuttonup                 raiseevent mouseleftbuttonclick(nothing, new mouseeventargs(mousebuttons.left, 1, mousedata.pt.x, mousedata.pt.y, 0))          end select         return callnexthookex(mousehookid, ncode, wparam, lparam)     end function

how possible recognize double click?

obviously there isn't mousebuttons.leftdoubleclick, that's i'm after.


would willing give suggestion on how go doing this? i'd appreciate it.

if @ codeplex globalmousekeyhook project, handling mousedouble click events globally both left , right mouse buttons.

this library attaches windows global hooks, tracks keyboard , mouse clicks , movement , raises common .net events keyeventargs , mouseeventargs, can retrieve information need:
mouse coordinates
mouse buttons clicked
mouse wheel scrolls
key presses , releases
special key states
