Paul,
You may take a look at MapWizAX, an OCX control, which will make the
integrated mapping in VB much easier, esp. the callback function.
You can get it for a free trial at:

Subject: MI: Invoking MapInfo Pro from VB application
>Dear all,
>
>From my VB application I'd like to launch MapInfo Professional via a menu
>item, and/or a toolbar. The problem I have is that my application when
>running isn't going to know where MapInfo has been installed on the
machine,
>if at all. Can anybody please tell me how I can determine whether MapInfo
>Pro. has been installed on a machine, and if so, how to launch it?.
>
>I've already tried the following code, which apparently works for launching
>"Excel", but it didn't work for MapInfo;
>
>Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
> (ByVal hWnd As Long, ByVal lpOperation As String, ByVal lpFile As
>String, _
> ByVal lpParameters As String, ByVal lpDirectory As String, _
> ByVal nShowCmd As Long) As Long
>
>Private Sub cmdLaunchMapInfo_Click()

> Dim ReturnedStatus As Long

>'Launch MapInfo
> ReturnedStatus = ShellExecute(Me.hwnd, vbNull, "Mapinfo", vbNull,
vbNull,
