RemoteApp receives multiple KeyUp events without any keys being pressed

hi all,

i have simple winforms app using try , track down happening keyboard events when using remoteapp.

basically have form , textbox track keydown, keypress , keyup events.

as start app via remoteapp receive multiple keyup events without pressing key.

does know why remoteapp sending these random keyup events.

the code of simple test app follows:

public class form1      dim lst new list(of string)      private sub addtolist(str string)      lst.add(str)    end sub      private sub textbox1_keydown(sender object, e system.windows.forms.keyeventargs) handles textbox1.keydown      addtolist("txt keydown" & vbtab & "keycode " & e.keycode)    end sub      private sub textbox1_keypress(sender object, e system.windows.forms.keypresseventargs) handles textbox1.keypress      addtolist("txt keypress" & vbtab & "keychar " & e.keychar)    end sub      private sub textbox1_keyup(sender object, e system.windows.forms.keyeventargs) handles textbox1.keyup      addtolist("txt keyup" & vbtab & "keycode " & e.keycode)    end sub      private sub form1_formclosing(sender object, e system.windows.forms.formclosingeventargs) handles me.formclosing      addtolist("form closing")      io.file.appendalllines(application.startuppath & "\simplekeyup_v2.txt", lst)    end sub      private sub form1_keydown(sender object, e system.windows.forms.keyeventargs) handles me.keydown      addtolist("form keydown" & vbtab & "keycode " & e.keycode)    end sub      private sub form1_keypress(sender object, e system.windows.forms.keypresseventargs) handles me.keypress      addtolist("form keypress" & vbtab & "keychar " & e.keychar)    end sub      private sub form1_keyup(sender object, e system.windows.forms.keyeventargs) handles me.keyup      addtolist("form keyup" & vbtab & "keycode " & e.keycode)    end sub      private sub form1_load(sender object, e system.eventargs) handles me.load      addtolist("form load")    end sub  end class  

simply opening , closing app via remoteapp gives following results:

form load
form keyup keycode 9
txt keyup keycode 9
form keyup keycode 16
txt keyup keycode 16
form keyup keycode 16
txt keyup keycode 16
form keyup keycode 17
txt keyup keycode 17
form keyup keycode 17
txt keyup keycode 17
form keyup keycode 9
txt keyup keycode 9
form keyup keycode 18
txt keyup keycode 18
form keyup keycode 9
txt keyup keycode 9
form keyup keycode 18
txt keyup keycode 18
form keyup keycode 9
txt keyup keycode 9
form closing
