Excel SendInput VB基本示例

我希望有人能帮忙，我试图找到一个模拟键盘命令的SendInput代码示例，我希望找到记事本窗口并输入测试消息

我最初在一个项目中使用SendKeys，SendKeys功能使我能够将键盘命令转发到我们工作场所使用的定制软件

我希望有人能帮忙，网上的例子似乎不起作用

是否还有人可以建议SendInput方法是否具有侵入性，即它是否会对收件人窗口造成任何损坏

SendKey方法奏效了，但是可靠性似乎很差

非常感谢

萨拉

我在网上找到了下面的代码，下面的是SendInput方法吗？我注意到使用了术语“SendKey”

Private Declare Function SendInput Lib "user32.dll" _
 (ByVal nInputs As Long, ByRef pInputs As Any, _
 ByVal cbSize As Long) As Long
Private Declare Function VkKeyScan Lib "user32" Alias "VkKeyScanA" _
 (ByVal cChar As Byte) As Integer

Private Type KeyboardInput      '   typedef struct tagINPUT {
 dwType As Long                '     DWORD type;
 wVK As Integer                '     union {MOUSEINPUT mi;
 wScan As Integer              '               KEYBDINPUT ki;
 dwFlags As Long               '               HARDWAREINPUT hi;
 dwTime As Long                '              };
 dwExtraInfo As Long           '     }INPUT, *PINPUT;
 dwPadding As Currency         '   8 extra bytes, because mouses take more.
End Type

Private Const INPUT_MOUSE As Long = 0
Private Const INPUT_KEYBOARD As Long = 1
Private Const KEYEVENTF_KEYUP As Long = 2
Private Const VK_LSHIFT = &HA0

Public Sub SendKey(ByVal Data As String)
Dim ki() As KeyboardInput
Dim i As Long
Dim o As Long ' output buffer position
Dim c As String ' character

ReDim ki(1 To Len(Data) * 4) As KeyboardInput
o = 1

For i = 1 To Len(Data)
 c = Mid$(Data, i, 1)
 Select Case c
   Case "A" To "Z": ' upper case
     ki(o).dwType = INPUT_KEYBOARD 'shift down
     ki(o).wVK = VK_LSHIFT
     ki(o + 1) = ki(o) ' key down
     ki(o + 1).wVK = VkKeyScan(Asc(c))
     ki(o + 2) = ki(o + 1) ' key up
     ki(o + 2).dwFlags = KEYEVENTF_KEYUP
     ki(o + 3) = ki(o) ' shift up
     ki(o + 3).dwFlags = KEYEVENTF_KEYUP
     o = o + 4
   Case Else: ' lower case
     ki(o).dwType = INPUT_KEYBOARD
     ki(o).wVK = VkKeyScan(Asc(c))
     ki(o + 1) = ki(o)
     ki(o + 1).dwFlags = KEYEVENTF_KEYUP
     o = o + 2
 End Select
Next i

Debug.Print SendInput(o - 1, ki(1), LenB(ki(1))),
Debug.Print Err.LastDllError
End Sub

Private Sub Command1_Click()
Text1.Text = ""
Text1.SetFocus
DoEvents
Call SendKey("This Is A Test")
End Sub

下面的代码不是针对VB.net的，而是针对VB/VBA的，它类似于sendkeys方法，但可能更可靠一些，因为它专门将密钥发送到目标应用程序。我得到它的帖子也显示了sendkeys方法

Public Declare Function FindWindowX Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, _
ByVal hWnd2 As Long, ByVal lpsz1 As Long, ByVal lpsz2 As Long) As Long

Public Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long

Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, _
ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long

Public Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Integer, ByVal lParam As Integer) As Long

Private Const WM_KEYDOWN = &H100
Private Const WM_KEYUP = &H101

Sub Three()
    hWind = FindWindow(vbNullString, "Untitled - Notepad")
    cWind = FindWindowX(hWind, 0, 0, 0)
    Debug.Print PostMessage(cWind, WM_KEYDOWN, vbKeyA, 0)
    Debug.Print PostMessage(cWind, WM_KEYDOWN, vbKeyB, 0)
    Debug.Print PostMessage(cWind, WM_KEYDOWN, vbKeyC, 0)
End Sub

如果将其粘贴到Excel/VBA中的新模块中并运行记事本的新实例，则在执行子模块时，记事本中应显示abc

我不知道使用此方法或sendkeys方法会如何损坏目标窗口。只要消息的时间正确，而不是同时向窗口发送成吨的字符，就不会引起任何问题

我曾设法在网上找到另一个SendInput脚本，我已将其复制到下面，供其他可能感兴趣的人使用

我一直在使用SendKeys从电子表格中复制数据并将其输入到工作系统中，这节省了宝贵的时间，因为需要输入大量的信息

SeNKEKS函数没有任何问题，但由于可靠性问题，我不得不考虑替代方案，SeNeDebug会导致任何问题到另一个窗口，即除了模拟键盘按钮，它是否会干扰目标窗口的其他功能？< /P>

谢谢Nick，我现在使用的是SendInput方法，而不是SendMessage或PostMessage。谢谢Nick，我现在使用的是SendInput方法，而不是SendMessage或PostMessage。即使在添加PtrSafe时，也不能使用64位。即使在添加PtrSafe时，也不能使用64位。这在MS Access中也非常有效，谢谢！这在MS Access中也非常有效，谢谢！
