private void lstv_stock_mouseup(object sender, mouseeventargs e) {     switch (e.button)     {          // right mouse click             case mousebuttons.right:                   contextmenu mycontextmenu = new contextmenu();                  menuitem menuitem1 = new menuitem("new product");                 menuitem menuitem2 = new menuitem("delete");                 menuitem menuitem3 = new menuitem("add quantity");                   // clear added menuitems.                 mycontextmenu.menuitems.clear();                  mycontextmenu.menuitems.add(menuitem1);                 mycontextmenu.menuitems.add(menuitem2);                 mycontextmenu.menuitems.add(menuitem3);                  if (lstv_stock.selecteditems.count > 0)                  {                      foreach (listviewitem item in lstv_stock.selecteditems)                     {                         mycontextmenu.menuitems[1].visible = true;                         mycontextmenu.menuitems[2].visible = true;                         mycontextmenu.menuitems[0].visible = false;                     }                  }                 else                 {                     mycontextmenu.menuitems[1].visible = false;                     mycontextmenu.menuitems[2].visible = false;                     mycontextmenu.menuitems[0].visible = true;                 }                  mycontextmenu.show(lstv_stock, this.pointtoclient(cursor.position), leftrightalignment.right);                    menuitem1.click += new system.eventhandler(this.menuitem1_click);                   break;          }

for positioning, can replace your

mycontextmenu.show(lstv_stock, this.pointtoclient(cursor.position), leftrightalignment.right);

to 

mycontextmenu.show(lstv_stock, e.location(), leftrightalignment.right);

or point e.x,e.y. not this.pointtoclient, mouseeventargs generating event. can check wahat mouseevent have here.

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

c++ - Warning : overflow in implicit constant conversion -

-
in following program, line 5 give overflow warning expected, surprisingly line 4 doesn't give warning in gcc: http://www.ideone.com/u0bxn int main() { int = 256; char c1 = i; //line 4 char c2 = 256; //line 5 return 0; } i thinking both lines should give overflow warning. or there i'm missing? the topic led me experiment this: typedef type checking? there said following(which deleted answer, because when run it, didn't show had expected): //however, you'll warning case: typedef int t1; typedef char t2; t1 x = 256; t2 y = x; //possible overflow warning! (but doesn't give warning :() -wall doesn't include many options. -wconversion 1 of them , warns behavior you're interested in. see http://gcc.gnu.org/onlinedocs/gcc/warning-options.html
