C++ Builder IDE, DecimalSeparator fails

1. DecimalSeparator

Hi,

I have this part of code in my app to check if my
'dictionary version' is valid:


   bool TDiMainForm::IsDictionaryVerValid( AnsiString Version )  // <---  
"2.0"
   {
      bool Result = true;

      try
      {
         DecimalSeparator = '.';

         // C() is just LoadStr()
         float Min = StrToFloat( C(IDS_SER_MAIN_APP_DB_VER_MIN) ); // <---  
"2.0"
         float Max = StrToFloat( C(IDS_SER_MAIN_APP_DB_VER_MAX) ); // <---  
"2.5"
         float Ver = StrToFloat( Version );

         if ( ( Ver < Min ) || ( Ver > Max ) )
         {
            Result = false;
         }
      }
      catch ( const Exception &e )
      {
         Result = false;
      }

      return ( Result );
   }

On maybe 500 copies of the program no one complained because
of variety of Regionional Options, but in 2 cases so far the result
of this check was 'false' ?!

When I suggested them to manualy change the Regional Options
and set DecimalSymbol - the app worked!

I know that this seems to be *impossible* but, do you see
what could be wrong to this routine?

3. How to detect proxy failed or remote host failed

Hi All,

I have an application where I am accessing resources from internet/intranet. 
I am using HttpWebRequest/HttpWebResponse. The connection is made through 
proxy.

During error handling I want to detect if the connection is failed while 
accessing proxy or while accessing remote host. If proxy is failed I want to 
do proxy recovery. (In case multiple proxies are specified then fail over to 
another proxy), in case remote host is failed I just want report the error.

When I catch WebException, the status of WebException in both the cases 
(when proxy is down or remote host is down) is ConnectFailure.

According to MSDN help, if status == ConnectFailure then proxy or firewall 
is failed, but this is not true. I checked by making direct connection 
(without proxy) and if my remote host is down still I get ConnectFailure.

According to MSDN help, HttpWebRequest.Address is suppose to return the 
actaul URL that has responded but I checked even when my proxy is down still 
the HttpWebRequest.Address is the original address pointing to remote host.

I checked the InnerException of the WebException I am getting,it clearly 
showes two different error messages when proxy is down and host is down.

Can anybody help me in detecting if proxy is failed or remote host ?

5. CDataExchange::Fail() fails

When I try to call CDataExchange::Fail() function in my member I get the 
following list of errors.

<ERRORS>
error C2059: syntax error : 'constant'
error C2039: 'func1' : is not a member of 'CDataExchange'
error C2039: 'func2' : is not a member of 'CDataExchange'
error C2039: 'AfxMessageBox' : is not a member of 'CDataExchange'
error C2039: 'pDX' : is not a member of 'CDataExchange'
</ERRORS>

The problematic code is below.

<CODE>
CFoo::MyDDV( CDataExchange* pDX )
{
 if( pDX->m_bSaveAndValidate )
 {
  if( ! func1() )
    {
   AfxMessageBox( "ERROR.", MB_ICONEXCLAMATION );
      pDX->Fail();
    }

 }

}
</CODE>

What is wrong?

Thanks
