I wanted to pragmatically change the content of a cell. So I have tried something like this

Private Structure Items
Dim ID as Integer
Dim Name as String
End Structure

Dim objItem as Items
Private Sub AddItem()
objItem.ID = 1
objItem.Name = "Name"
objectlistview.AddObject(objItem)
End Sub

Private sub ChangeItem()
objItem.Name = "MyName"
objectlistview.RefreshObject(objItem)
End Sum

AddItem() method is working fine. But ChangeItem() method doesn't work. What's wrong with code

I have a customized WPF button control and I want to use this control with a WinForm application. I know how to use WPF user controls with WinForm using ElementHost. But I have no idea to use any single control (not a user control) with all its members with a WinForm application. Can you suggest me a good way to achieve this

I didn't use any Insert statement. Just used CommandBuilder class to generate SQL statements

Is it possible to insert rows in to a MS Access table with a Auto number field using a CommandBuilder. I tried that but it's getting following error. Syntax error in Insert in to statement. I did same thing to a table which doesn't have a auto number field. It worked. I think the problem is that auto number field. What's the solution for this problem.

Please can you show me the code to set a new value for lParam variable. Since I am not familiar with hooks I can't understand how to do that.

I used following code to implement my project as you suggest

Private Const WH_KEYBOARD_LL As Integer = 13
Private Const WM_KEYUP As Integer = &H101
Private Const WM_SYSKEYUP As Integer = &H105
Private proc As LowLevelKeyboardProcDelegate = AddressOf HookCallback
Private hookID As IntPtr

Private Delegate Function LowLevelKeyboardProcDelegate(ByVal nCode As Integer, ByVal wParam As IntPtr, \_
    ByVal lParam As IntPtr) As IntPtr

<DllImport("user32")> \_
Private Shared Function SetWindowsHookEx(ByVal idHook As Integer, ByVal lpfn As LowLevelKeyboardProcDelegate, \_
    ByVal hMod As IntPtr, ByVal dwThreadId As UInteger) As IntPtr
End Function

<DllImport("user32.dll")> \_
Private Shared Function UnhookWindowsHookEx(ByVal hhk As IntPtr) As <MarshalAs(UnmanagedType.Bool)> Boolean
End Function

<DllImport("user32.dll")> \_
Private Shared Function CallNextHookEx(ByVal hhk As IntPtr, ByVal nCode As Integer, ByVal wParam As IntPtr, \_
    ByVal lParam As IntPtr) As IntPtr
End Function

<DllImport("kernel32.dll", CharSet:=CharSet.Unicode)> \_
Private Shared Function GetModuleHandle(ByVal lpModuleName As String) As IntPtr
End Function

Sub New()
    ' This call is required by the Windows Form Designer.
    InitializeComponent()
    ' Add any initialization after the InitializeComponent() call.
    hookID = SetHook(proc)
End Sub

Private Sub Form1\_FormClosing(ByVal sender As Object, ByVal e As FormClosingEventArgs) Handles Me.FormClosing
    UnhookWindowsHookEx(hookID)
End Sub

Private Function SetHook(ByVal proc As LowLevelKeyboardProcDelegate) As IntPtr
    Using curProcess As Process = Process.GetCurrentProcess()
        Using curModule As ProcessModule = curProcess.MainModule
            Return SetWindowsHookEx(WH\_KEYBOARD\_LL, proc, GetModuleHandle(curModule.ModuleName), 0)
        End Using
    End Using
End Function

But there is a problem in this function

Private Function HookCallback(ByVal nCode As Integer, ByVal wParam As IntPtr, ByVal lParam As IntPtr) As IntPtr

    If nCode Then
        Dim vkCode As Integer = Marshal.ReadInt32(lParam)
        If vkCode = Keys.A Then
            SendKeys.Send("B")
            Return CType(1, IntPtr)
        End If
    End If
     Return CallNextHookEx(hookID, nCode, wParam, lParam)
End Fu

As I know, .NET Framework doesn't support global hooks and I am not familiar with hooks . Can you suggest another possible way to do this with .NET

My requirement is to create a transliteration application. If I do this as you suggested, its ability limits to one application. But I want allow users to do transliteration on any window. To do so first I want to avoid typing English letters and track the key which was pressed. Later it will send translated letter to the active window. That's what I want.

Is there a way to avoid typing alphabetic keys (A-Z) in any window and track the key which was pressed at same time. I tried to use BlockInput API. But it disabled all keys in keyboard. I hope your kind reply. Thanks
