假面骑士铠武巴隆篇:VB做的程序怎样才能一直处于活动状态

你的意思是用vb实现全局键盘钩子。
很不幸说，vb无法实现全局钩子。

键盘钩子应该可以实现的。。

思路：
1、timer控件实现简单，耗费内存。
2、系统注册表注册热键。

'窗体中option explicit

private sub form_load()dim ret as long '记录原来的window程序地址 prewinproc = getwindowlong(me.hwnd, gwl_wndproc) '用自定义程序代替原来的window程序 ret = setwindowlong(me.hwnd, gwl_wndproc, addressof wndproc) idhotkey = 1 'in the range ＆h0000 through ＆hbfff modifiers = mod_alt '辅助键为alt uvirtkey1 = vbkeyq '注册的热键为alt+q '注册热键 ret = registerhotkey(me.hwnd, idhotkey, modifiers, uvirtkey1) if ret = 0 then msgbox "注册热键失败,请使用其它热键!", vbcritical, "错误" end ifend sub

private sub form_queryunload(cancel as integer, unloadmode as integer)dim ret as long '取消message的截取，使之送往原来的window程序 ret = setwindowlong(me.hwnd, gwl_wndproc, prewinproc) call unregisterhotkey(me.hwnd, uvirtkey1)end sub

'模块中

'以下程序放在模块中option explicit
