Hello,

I'm creating a client server application using the TSocketConnection.

Retrieving data from the server is working fine. But,

At the server side i have created a method in the Type library as follows:
Method - ShowInfo
Params sheet
retval = HRESULT
name = id
type   = int
modifier =  [in]

STDMETHODIMP TMyAppServerImpl::ShowInfo(int id)
{
  try
  {
    ShowMessage(IntToStr(id));
  }
  catch(Exception &e)
  {
    return Error(e.Message.c_str(),IID_IMyAppServer);
  }
  return S_OK;
}


At the client side i have a function:

SetInfo()
{
    IMyAppServerDisp
TempInterface(LPDISPATCH(SocketConnection1->AppServer));
    TempInterface->ShowInfo((int)10);
}

If i run SetInfo() i'll get the following message:

p->QueryInterface(GetID(),(LPVOID*)(&intf))  No such interface supported
utilcls.h/1977

Can someone help me with this ?


I'v installed servicepack 1 en 2.


Thanks in advance Rob.

Insert in your Server_TLB.h :
#define IProviderPtr IProvider* 
You have to do this every time the type library has been refreshed!

I'v inserted the define statement and rebuild the server and the client.
But i still get the same error message.

When i use a DCOMconnection on my client it's working.

Can you help me please ?
