不知道发到这个版块对么，我是菜鸟，帮帮我啊
QTP自带的订票系统，目的地是固定的London，然后起始地做循环，但起始地不能是London，怎么加个if语句啊

Dim IntNumber_flyfrom,IntNumber_flytime

Dim Str_flyfrom,Str_flytime

Window("Flight Reservation").Activate

IntNumber_flyfrom=Window("Flight Reservation").WinComboBox("Fly From:").GetItemsCount

For i=0 to IntNumber_flyfrom-1



Window("Flight Reservation").WinButton("Button").Click

Window("Flight Reservation").ActiveX("MaskEdBox").Type "040411"

Str_flyfrom=Window("Flight Reservation").WinComboBox("Fly From:").GetItem(i)

Window("Flight Reservation").WinComboBox("Fly From:").Select  Str_flyfrom

Window("Flight Reservation").WinComboBox("Fly To:").Select "London"

'是这里要加个if语句么

Window("Flight Reservation").WinButton("FLIGHT").Click

	IntNumber_flytime=Window("Flight Reservation").Dialog("Flights Table").WinList("From").GetItemsCount

	For k=0 to IntNumber_flytime-1

		Str_flytime=Window("Flight Reservation").Dialog("Flights Table").WinList("From").GetItem(k)

		Window("Flight Reservation").Dialog("Flights Table").WinList("From").Select Str_flytime

		Window("Flight Reservation").Dialog("Flights Table").WinButton("OK").Click

		Window("Flight Reservation").WinEdit("Name:").Set "qwe"

		Window("Flight Reservation").WinRadioButton("First").Set

		Window("Flight Reservation").WinEdit("Tickets:").SetSelection 0,1

		Window("Flight Reservation").WinEdit("Tickets:").Set "2"

		Window("Flight Reservation").WinButton("Insert Order").Click

		Window("Flight Reservation").WinButton("Button").Click

		Window("Flight Reservation").ActiveX("MaskEdBox").Type "040411"

		Str_flyfrom=Window("Flight Reservation").WinComboBox("Fly From:").GetItem(i)

		Window("Flight Reservation").WinComboBox("Fly From:").Select  Str_flyfrom

		Window("Flight Reservation").WinComboBox("Fly To:").Select "London"

		Window("Flight Reservation").WinButton("FLIGHT").Click

	Window("Flight Reservation").Dialog("Flights Table").WinButton("Cancel").Click
