vb.net - MDI menu shortcut not working while other Form active -

-

my project have mdi form , 's have menu many shortcut shortcut work fine while 's focus when open form shortcut stop working because mdi form not active how can send keyboard press mdi form trigger menu shortcut

this how open child window 

 frmchild.owner = me  frmchild.show()

i make key press , key down events static , public , them in key press ,key down in child form 's work , sent keyboard input mdi form menu shortcut never trigger.

frmmdi

public shared sub frmmdi_keydown(sender object, e keyeventargs) handles me.keydown  end sub

frmchild

private sub frmchild_keydown(sender object, e keyeventargs) handles me.keydown     frmmdi.frmmdi_keydown(sender, e) end sub

thanks.

you don't need call in child keydown handler mdiparent keydown handler. menu shortcut of parent work without this. reason it's not working because should have 

frmchild.mdiparent = me

instead of 

frmchild.owner = me
