Hey ! I'm building an MFC app in Visual Studio 2008 which classifies textures and I need some sort of lightweight database to hold the characteristics (just some doubles and strings) which can be: -carried around with the app on different computers; -be able to perform queries on it from the app (searches , updates ,inserts ,etc); Currently I'm looking into SQL compact edition because it was very easy to create from Visual Studio ( I also need only one table) but I having a hard time connecting and updating the db from C++. This is what I've found on msdn regarding C++ and SQLCE: public: void createSqlCeConnection(){ SqlCeConnection* myConnection = new SqlCeConnection(); myConnection->ConnectionString = "DataSource = blabla.sdf"; MessageBox::Show(String::Format( S"Connection State: {0}", __box(myConnection->State))); } Unfortunately my experience with .net apps is pretty limited. Hopefully you bright minds could tell me if I'm on the right path and what links and includes should I add for this to work with an C++ MFC projects. Thanks !
