xxx = CType(**** , CShowHelloWorld)

这个是VB.NET的，VB6.0中没有这个功能

看下这段示例代码，但我执行时会内存错误

'Example Name:Call Procedure
'Create a new project and add this code to Form1
Private Declare Function FreeLibrary Lib "kernel32" (ByVal hLibModule As Long) As Long
Private Declare Function LoadLibrary Lib "kernel32" Alias "LoadLibraryA" (ByVal lpLibFileName As String) As Long
Private Declare Function GetProcAddress Lib "kernel32" (ByVal hModule As Long, ByVal lpProcName As String) As Long
Private Declare Function CallWindowProc Lib "user32" Alias "CallWindowProcA" (ByVal lpPrevWndFunc As Long, ByVal hWnd As Long, ByVal Msg As Any, ByVal wParam As Any, ByVal lParam As Any) As Long
Private Sub Form_Load()
    On Error Resume Next
    'KPD-Team 1999
    'URL: http://www.allapi.net/
    'E-Mail: KPDTeam@Allapi.net
    'We're going to call an API-function, without declaring it!
    Dim lb As Long, pa As Long
    'map 'user32' into the address space of the calling process.
    lb = LoadLibrary("user32")
    'retrieve the address of 'SetWindowTextA'
    pa = GetProcAddress(lb, "SetWindowTextA")
    'Call the SetWindowTextA-function
    CallWindowProc pa, Me.hWnd, "Hello !", ByVal 0&, ByVal 0&
    'unmap the library's address
    FreeLibrary lb
End Sub

要是有参数就会很麻烦.........
