Error in buttons

[fxg4758]

Hi. I put a control in the a window by anygui, but now i have a problem with the buttons. They can call functions, but if i try to Send("{F5}"), for example, they only run the another code and not the send function.

$ctr = NET_ControlGetHandleByName($test1, "", "control")

$targetctl = _GuiTarget ($test1, 1, "", $ctr)

$BtEcra = _TargetAddButton ( "", 3, 1, 32, 32, $BS_ICON,"", $targetctl)

GUICtrlSetImage(-1, "shell32.dll", 243,0)

GUICtrlSetTip(-1, "Msg","",0,1)

$BtEcra = $BtEcra[0]

GUISetState()

In this code, is something missing for buttons to call the functions? And when i active the buttons, the mouse cursor is a little odd in the rest of the window. Thanks for any information!
