为何必须选择一次才能读取数据，默认数据的话一闪而过，为什么？

先给变量设置一个初值
Dim $xz= "1.bat"
$Form1 = GUICreate("Form1", 183, 92, -1,-1)

等高手来解答 不明白楼主说什么。，
不明白楼主为什么要搞复杂化？另外如楼上所说赋值，也可方法2,也可其他，多的是
$Form1 = GUICreate("Form1", 183, 92, -1,-1)
$Combo1 = GUICtrlCreateCombo("", 16, 8, 145, 25)
GUICtrlSetData(-1,'1|2|3',1)
$Button1 = GUICtrlCreateButton("Button1", 88, 40, 75, 25)
GUISetState(@SW_SHOW)
While 1
$nMsg = GUIGetMsg()
Switch $nMsg
Case -3
Exit
Case $Button1
MsgBox(64,'',GUICtrlRead($Combo1)&'.bat')
EndSwitch
WEnd2#include <ButtonConstants.au3>

Send('{down}')
Send('{up}')
While 1
$nMsg = GUIGetMsg()
Switch $nMsg
Case $GUI_EVENT_CLOSE
Exit
Case $Combo1
Switch GUICtrlRead($Combo1)
Case "1"
$xz = '1.bat'
Case "2"
$xz = '2.bat'
Case "3"
$xz = '3.bat'
EndSwitch
Case $Button1
MsgBox(64,'',$xz)
EndSwitch
WEnd 回复 4# kn007
谢谢啦
这两种办法我知道，我是想问有更好的办法没 变量 $xz 需要先声明
