在Windows中我們可以用“Ctrl＋Shift”鍵來(lái)調(diào)入或切換中文輸入法，但是這樣做每次都是使位于輸入法列表頂端的那個(gè)輸入法首先被調(diào)用。通常我們都要連續(xù)按好幾次“Ctrl＋Shift”才能將習(xí)慣的輸入法調(diào)出。我編制了一段小程序，通過它可以把任意一個(gè)輸入法放在輸入法列表的頂端。
它的原理是：使用LoadKeyboardLayout函數(shù)可以改變輸入法的順序，只要在第一個(gè)參數(shù)中傳遞目標(biāo)輸入法的KeyboardlayoutName，第二個(gè)參數(shù)用KLF_REORDER就可以了。
例如，aa = LoadKeyboardLayout(″00000409″, KLF_REORDER) 使英文變成第一。那怎樣獲得KeyboardlayoutName呢？因?yàn)槭褂肎etKeyboardLayoutname可以返回當(dāng)前輸入法的KeyboardlayoutName，所以我們可以先用GetKeyboardLayoutList 函數(shù)來(lái)取得所有輸入法，再用activateKeyboardlayout()函數(shù)設(shè)置當(dāng)前輸入法，最后就可以得到它的KeyboardlayoutName了。具體步驟如下：
打開VB后選擇標(biāo)準(zhǔn)的EXE文檔，在Form1上添加一個(gè)Combobox和一個(gè)command控件，輸入以下程序。
′以下的API函數(shù)用于輸入法操作
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′如果用戶尚未選擇輸入法，顯示出錯(cuò)信息
MsgBox ″請(qǐng)先選擇一個(gè)輸入法″
Exit Sub
End If
′改變輸入法順序
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) ′取得目前的輸入法
NoOfKBDLayout = GetKeyboardLayoutList(25, hKB(0)) ′取得所有輸入法
′ReDim layoutlist(NoOfKBDLayout) As String
For i = 1 To NoOfKBDLayout
If ImmIsIME(hKB(i － 1)) = 1 Then ′中文輸入法
BuffLen = 255
RetCount = ImmGetDescription(hKB(i － 1), Buff, BuffLen)
RetStr = Left(Buff, RetCount)
Combo1.AddItem RetStr
Else
RetStr = ″English (American)″ ′英文輸入法
Combo1.AddItem RetStr
End If
Next
ActivateKeyboardLayout hCurKBDLayout, 0 ′恢復(fù)原來(lái)的輸入法
End Sub |
運(yùn)行后，在combobox中選擇目標(biāo)輸入法，按下command即可。
