----------------------------------------------------------- From: spark Message 2 in Discussion hi Sukh, yes this is possible. you basically use a mechanism called P/Invoke. P/Invoke lets you call functions from traditional c# programs without much effort. Its rather easy to do - take a look at that MCI Console player I had posted some time back. http://groups.msn.com/cochindotnet/general.msnw?action=get_message&mview=0&ID_Message=163&LastModified=4675432728935320706 There is source code for a small cpp program which compiles to a dll and and c# program that uses teh function inside that dll. take a look at that. this is the line that it responsible for a lot of the magic [DllImport("mci.dll")] static extern int mci(string cmd,StringBuilder sb); Here you could give your dll name like : [DllImport("winscard.dll")] static extern LONG SCardEstablishContext( DWORD dwScope, //<--- change these types LPCVOID pvReserved1, LPCVOID pvReserved2, LPSCARDCONTEXT phContext ); once you have done this, you will need to change each of teh parameters of this funtion to .net compatible types - so that when you pass a value from .net it get translated to its apprpriate type in the c++ context. did you understand ? regards rosh ----------------------------------------------------------- To stop getting this e-mail, or change how often it arrives, go to your E-mail Settings. http://groups.msn.com/cochindotnet/_emailsettings.msnw Need help?
