Thanks everyone, unfortunatly I'm still stuck.....
@ Stephane, this is what I'm doing, but it's not working:
sizeof( test.A ) + sizeof( double ) * test.A.size() + sizeof( test.B ) +
sizeof( double ) * test.B.size() + sizeof( bool ) * 2
@ Guillame
Thanks, I tryed your example but I'm probably doing it the wrong way:
Foo Test;
//Set some values
Test.A->pushback(12);
Test.B->pushback(24);
Test.B->pushback(32);
Test.C->pushback(true);
Test.D->pushback(false);
myMap.PutItemValue( i, (unsigned char*)&Test, sizeof( Foo )) ;
// Get them back
const unsigned char* pInternalData = NULL ;
UINT cntData = 0 ;
myMap.GetItemValue( 0, pInternalData, cntData ) ;
Foo *pData = (Foo*) pInternalData ;
if(pData)
{
Application().LogMessage("nb "+CString(pData->A->size()));
}
this return empty vector....
@MAB
Could you point me to some ressources on the web about this?
Thanks!!
