在Windows中我们可以用“Ctrl＋Shift”键来调入或切换中文输入法，但是这样做每次都是使位于输入法列表顶端的那个输入法首先被调用。通常我们都要连续按好几次“Ctrl＋Shift”才能将习惯的输入法调出。我编制了一段小程序，通过它可以把任意一个输入法放在输入法列表的顶端。
它的原理是：使用LoadKeyboardLayout函数可以改变输入法的顺序，只要在第一个参数中传递目标输入法的KeyboardlayoutName，第二个参数用KLF_REORDER就可以了。
例如，aa = LoadKeyboardLayout(″00000409″, KLF_REORDER) 使英文变成第一。那怎样获得KeyboardlayoutName呢？因为使用GetKeyboardLayoutname可以返回当前输入法的KeyboardlayoutName，所以我们可以先用GetKeyboardLayoutList 函数来取得所有输入法，再用activateKeyboardlayout()函数设置当前输入法，最后就可以得到它的KeyboardlayoutName了。具体步骤如下：
打开VB后选择标准的EXE文档，在Form1上添加一个Combobox和一个command控件，输入以下程序。
′以下的API函数用于输入法操作
Private Declare Function GetKeyboardLayoutList Lib ″user32″ _
(ByVal nBuff As Long, lpList As Long) As Long
Private Declare Function ImmGetDescription Lib ″imm32.dll″ _
Alias ″ImmGetDescriptionA″ (ByVal hkl As Long, _
ByVal lpsz As String, ByVal uBufLen As Long) As Long
Private Declare Function ImmIsIME Lib ″imm32.dll″ (ByVal hkl As Long) As Long
Private Declare Function ActivateKeyboardLayout Lib ″user32″ _
(ByVal hkl As Long, ByVal flags As Long) As Long
Private Declare Function GetKeyboardLayout Lib ″user32″ (ByVal dwLayout As Long)As Long
Private Declare Function GetKeyboardLayoutName Lib ″user32″ Alias _
″GetKeyboardLayoutNameA″ (ByVal pwszKLID As String) As Long
Private Declare Function LoadKeyboardLayout Lib ″user32″ Alias ″LoadKeyboardLayoutA″ _
(ByVal pwszKLID As String, ByVal flags As Long) As Long
Const KLF_REORDER = ＆H8
Private NoOfKBDLayout As Long, i As Long, j As Long
Private hKB(24) As Long, BuffLen As Long
Private Buff As String
Private RetStr As String
Private RetCount As Long
Private kln As String
Private Sub Command1_Click()
If Combo1.ListIndex = －1 Then′如果用户尚未选择输入法，显示出错信息
MsgBox ″请先选择一个输入法″
Exit Sub
End If
′改变输入法顺序
kln = String(8, 0)
ActivateKeyboardLayout hKB(Combo1.ListIndex), 0
res = GetKeyboardLayoutName(kln)
res = LoadKeyboardLayout(kln, KLF_REORDER)
ActivateKeyboardLayout hCurKBDLayout, 0
End Sub
Private Sub Form_Load()
Buff = String(255, 0)
hCurKBDLayout = GetKeyboardLayout(0) ′取得目前的输入法
NoOfKBDLayout = GetKeyboardLayoutList(25, hKB(0)) ′取得所有输入法
′ReDim layoutlist(NoOfKBDLayout) As String
For i = 1 To NoOfKBDLayout
If ImmIsIME(hKB(i － 1)) = 1 Then ′中文输入法
BuffLen = 255
RetCount = ImmGetDescription(hKB(i － 1), Buff, BuffLen)
RetStr = Left(Buff, RetCount)
Combo1.AddItem RetStr
Else
RetStr = ″English (American)″ ′英文输入法
Combo1.AddItem RetStr
End If
Next
ActivateKeyboardLayout hCurKBDLayout, 0 ′恢复原来的输入法
End Sub
运行后，在combobox中选择目标输入法，按下command即可。。 |
