You can specify different types of on-screen keyboards to be displayed.

To do this, change (from your program) the KeyboardName parameter in the registry at HKEY_CURRENT_USER\Software\ComfortSoftware\CKeyboard.

You have to do it before showing the on-screen keyboard with Windows Messages (see http://www.comfort-software.com/forum-t17.html).

char  KeyboardName[80];

COPYDATASTRUCT MyCDS;



   KeyboardName = "Standard";

// Fill the COPYDATA structure

// 

   MyCDS.dwData = 1;          // function identifier

   MyCDS.cbData = sizeof( KeyboardName );  // size of data

   MyCDS.lpData = &KeyboardName;           // data structure

//

// Call function, passing data in &MyCDS

//

   HWND hwDispatch = FindWindow( "TFirstForm", "CKeyboardFirstForm" );

   if( hwDispatch != NULL )

      SendMessage( hwDispatch,

                   WM_COPYDATA,

                   (WPARAM)(HWND) NULL,

                   (LPARAM) (LPVOID) &MyCDS );

Hi
I also had a problem using the registry to load different kb set for the floating kb . I wanted to load different kb before the user click the floating kb button but it did not work, it seems that it is not reading the kb setting on every click (bug?).

so I used the post msg approach and it is working ok now
thanks!

I am evaluating On-Screen Keyboard V4.0 with vb6
the code converted to vb:

Private Type COPYDATASTRUCT
dwData As Long
cbData As Long
lpData As Long
End Type

Private Const WM_COPYDATA = &H4A

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

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

Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" _
(hpvDest As Any, hpvSource As Any, ByVal cbCopy As Long)

Public Function VKBLoadKeyboard(ByVal xi_KeyboardName As String) As Boolean

Dim KeyboardName(1 To 255) As Byte
Dim hwnd As Long
Dim MyCDS As COPYDATASTRUCT
Dim sString As String

sString = Trim$(xi_KeyboardName)
If sString = "" Then Exit Function
Call CopyMemory(KeyboardName(1), ByVal sString, Len(sString))

' Fill the COPYDATA structure
'
MyCDS.dwData = 1 ' function identifier
MyCDS.cbData = Len(sString) + 1 ' size of data
MyCDS.lpData = VarPtr(KeyboardName(1)) ' data structure
'
' Call function, passing data in &MyCDS
'
hwnd = FindWindow("TFirstForm", "CKeyboardFirstForm")
If (hwnd <> 0) Then
Call SendMessage(hwnd, WM_COPYDATA, 0, MyCDS)
End If

End Function
