How can I convert a String* data to char*? Is it possible to do Type convertion between managed type and unmanaged type. Is there any article which gives an explanation on this type conversion? Please help. vini

But now I get another error when I include the namespace System::Runtime::InteropServices. error C2872: 'FILETIME' : ambiguous symbol could be 'D:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\WinDef.h(354) : _FILETIME FILETIME' or 'stdafx.cpp(0) : System::Runtime::InteropServices::FILETIME'. Kindly help. Vini

Now its fine. I changed my function call to IntPtr ip=System::Runtime::InteropServices::Marshal::StringToHGlobalAnsi("hello World"), instead of including the namespace in the using namespace stmt and then calling the function as IntPtr ip=Marshal::StringToHGlobalAnsi("Hello World"). Thanks for the help Vini
