请懂C++跟VB的帮个忙！谢谢

m_MsgAttach = RegisterWindowMessage(_T("SkypeControlAPIAttach"));
  m_MsgDiscover = RegisterWindowMessage(_T("SkypeControlAPIDiscover"));

再将discover消息广播出去

::SendMessage( HWND_BROADCAST, m_MsgDiscover, (WPARAM)m_hWnd, 0 )

skype如果有登录的话，会相应这个消息

long CALLBACK MainWndProc(HWND hWnd, UINT uiMessage, WPARAM uiParam, LPARAM ulParam)
{
    CskypetestView*  pVoiceManager = ( CskypetestView * ) ( ::GetWindowLong( hWnd, GWL_USERDATA ) );
LRESULT lReturnCode;
bool fIssueDefProc;

lReturnCode=0;
fIssueDefProc=false;

    switch (uiMessage)
    {
  case WM_COPYDATA:
  if( hGlobal_SkypeAPIWindowHandle==(HWND)uiParam )
    {
    PCOPYDATASTRUCT poCopyData=(PCOPYDATASTRUCT)ulParam;
    printf( "Message from Skype(%u): %.*s\n", poCopyData->dwData, poCopyData->cbData, poCopyData->lpData);
    lReturnCode=1;
    return 1;
    }
  break;

        default: 
  if( uiMessage==uiGlobal_MsgID_SkypeControlAPIAttach )
  {
    switch(ulParam)
    {
    case SKYPECONTROLAPI_ATTACH_SUCCESS:
