Hi, ALL,
I am trying to write an application that uses wxFileConfig on both
Windows and Linux.
I made the test file called "test.ini" and placed it in the appropriate place.

test.ini:

[Device1]
URL=www.google.com
Port=10001

[Device2]
URL=www.google.com
Port=10002

Now in the code here is what I do:

wxFileConfig *config = new wxFileConfig( "test.ini" );
wxString oldPath = config->GetPath();
wxString path = "Device";
wxString address;
int port;
devicenum = config->GetNumberOfGroups();
for( size_t i = 1; i <= devicenum; i++ )
{
        config->SetPath( path << i );
        if( !config->Read( "Port", &port ) )
        {
                printf( "There is a problem with configuration file.\r\n" );
                printf( "No port supplied for the device #%d", i );
                delete config;
                return -1;
        }
        if( config->Read( "Address", &address ) )
        {
                devices.push_back( new Device( address, port, false ) );
        }
        else if( config->Read( "URL", &address ) )
        {
                devices.push_back( new Device( address, port, true ) );
        }
        else
        {
                printf( "There is a problem with configuration file.\r\n" );
                printf( "No address/URL supplied for the device #%d", i );
                delete config;
                return -1;
        }
        path = "Device";

}

config->SetPath( oldPath );

The problem is that the loop succeeds on the first iteration for the
"[Device1]", but fails to read
the data on the second iteration for "[Device2]".

However if I change the code to read:

for( size_t i = 1; i <= devicenum; i++ )
{
        wxString test = wxString::Format( "Device%d", i );
        if( !config->Read( test + "/Port", &port ) )
        {
                printf( "There is a problem with configuration file.\r\n" );
                printf( "No port supplied for the device #%d", i );
                delete config;
                return -1;
        }
        if( config->Read( test + "/Address", &address ) )
        {
                devices.push_back( new Device( address, port, false ) );
        }
        else if( config->Read( test + "/URL", &address ) )
        {
                devices.push_back( new Device( address, port, true ) );
        }

}

I can read both "Device1" and "Device2" parts.
Is this a known problem?

I'm currently on Windows (7) with wx-2.9.4 compiled with MSVC-2010.

Thank you.
