Need help with SendInput

I’m trying to achieve mouse movements with SendInput.

There is code that got from Pinvoke, http://www.pinvoke.net/default.aspx/user32.SendInput

Code:

---

<DllImport("user32.dll", SetLastError = True)> _
Private Shared Function SendInput(ByVal nInputs As Integer, ByRef pInputs As InputLanguage,
ByVal cbSize As Integer) As Integer
End Function
Public Class Form1
    Private Declare Function SendInput Lib "user32.dll" (ByVal cInputs As Integer, ByRef pInputs As INPUT, ByVal cbSize As Integer) As Integer
    Private Structure INPUT
        Dim dwType As Integer
        Dim mkhi As MOUSEKEYBDHARDWAREINPUT
    End Structure

    Private Structure KEYBDINPUT
        Public wVk As Short
        Public wScan As Short
        Public dwFlags As Integer
        Public time As Integer
        Public dwExtraInfo As IntPtr
    End Structure

    Private Structure HARDWAREINPUT
        Public uMsg As Integer
        Public wParamL As Short
        Public wParamH As Short
    End Structure

    <StructLayout(LayoutKind.Explicit)> _
Private Structure MOUSEKEYBDHARDWAREINPUT
        <FieldOffset(0)> Public mi As MOUSEINPUT
        <FieldOffset(0)> Public ki As KEYBDINPUT
        <FieldOffset(0)> Public hi As HARDWAREINPUT
    End Structure

    Private Structure MOUSEINPUT
        Public dx As Integer
        Public dy As Integer
        Public mouseData As Integer
        Public dwFlags As Integer
        Public time As Integer
        Public dwExtraInfo As IntPtr
    End Structure
    Const INPUT_MOUSE As UInt32 = 0
    Const INPUT_KEYBOARD As Integer = 1
    Const INPUT_HARDWARE As Integer = 2
    Const KEYEVENTF_EXTENDEDKEY As UInt32 = &H1
    Const KEYEVENTF_KEYUP As UInt32 = &H2
    Const KEYEVENTF_UNICODE As UInt32 = &H4
    Const KEYEVENTF_SCANCODE As UInt32 = &H8
    Const XBUTTON1 As UInt32 = &H1
    Const XBUTTON2 As UInt32 = &H2
    Const MOUSEEVENTF_MOVE As UInt32 = &H1
    Const MOUSEEVENTF_LEFTDOWN As UInt32 = &H2
    Const MOUSEEVENTF_LEFTUP As UInt32 = &H4
    Const MOUSEEVENTF_RIGHTDOWN As UInt32 = &H8
    Const MOUSEEVENTF_RIGHTUP As UInt32 = &H10
    Const MOUSEEVENTF_MIDDLEDOWN As UInt32 = &H20
    Const MOUSEEVENTF_MIDDLEUP As UInt32 = &H40
    Const MOUSEEVENTF_XDOWN As UInt32 = &H80
    Const MOUSEEVENTF_XUP As UInt32 = &H100
    Const MOUSEEVENTF_WHEEL As UInt32 = &H800
    Const MOUSEEVENTF_VIRTUALDESK As UInt32 = &H4000
    Const MOUSEEVENTF_ABSOLUTE As UInt32 = &H8000


    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    End Sub
End Class

But it doesn’t work for me I’m getting those errors:

Error 1 Identifier expected. C:\Documents and 2 91 WindowsApplication1
Error 2 Type 'StructLayout' is not defined. C:\Documents and 26 6 WindowsApplication1
Error 3 Type 'FieldOffset' is not defined. C:\Documents and 28 10 WindowsApplication1
Error 4 Type 'FieldOffset' is not defined. C:\Documents and 29 10 WindowsApplication1
Error 5 Type 'FieldOffset' is not defined. C:\Documents and 30 10 WindowsApplication1

Please help!

I dunno man, that's kind of a big nasty mess to do what SetCursorPos already does in like 2 lines.

Code:

---

Private Declare Function SetCursorPos Lib "user32.dll" ( _
    ByVal x As Int32, _
    ByVal y As Int32) As Int32

---

Code:

---

Call SetCursorPos(X, Y)

---

Thanks bro, but I already knew that also you can use

Code:

---

Windows.Forms.Cursor.Position = New System.Drawing.Point(x, y)

---

But I don’t want my cursor to jump araound I want it to move from one point to another, like human would. Can you help me with this? :confused:

Alright, I just did this a day or so ago.

Check out this this post.

You'll have to convert it to .NET but that won't be a big deal compared to the nightmare that is SendInput. On the plus side, this example is Unmanaged so it wont be blocked by Vista/7 security garbage trash like the managed SendInput would in cases.

I'm still working on the SendInput just because I refuse to walk away whipped. Apparently nobody on the internet can get it right and those that can are guarding it like it were money. :sick:

When I get it squared away I'll post back with a very clear and detailed explanation.

Umm, if you manage to figure it out before I do, please post back here and give us all a break. :bigyello:

Ok 1 thing for sure.

If you add Imports System.Runtime.InteropServices to the first line of your class, it should clear up your warnings.
