I'm using MICROSOFT WINSOCK CONTROL 6.0 (not CSocket nor CAsyncSocket)
to send and receive data through sockets.

I'm getting an odd exception that seems to occour randomly (all
strange errors are seems randomly until solution is found) and
debugging I found that happens when I execute m_Winsock.SendData
(VARIANT).

Catching it doesn't seems to give me any information:

                try
                {
                        m_Winsock.SendData( v ); =

//v is a variant with correct

data
                }
                catch( CException* e )
                {
                        char info[300];
                        unsigned int code;
                        PUINT error_number = &co=

de;

e->GetErrorMessage( info, =

300, &code );

CString cadena;
cadena.Format("Error ocurr=

ed: %s",info); //info is empty!!!!

AfxMessageBox( "-->"+caden=

a );

e->Delete();
}

...unless I set a breakpoint inside the catch, where I see that is a
COleDispatchException.
What does it means?

I found a little more info about the error in "Variables" Window:

Since m_strDescription is empty, I don't know what's happening!!!
