I will call MyLogin() in my C#, how to deal with LPTSTR, pointer, and Struct. TOKEN_CONTEXT is a struct which was pass to MyLogin(). Thanks.
---------------------------------------------------------------------------------------------------------------------------
unsigned
int __declspec( dllexport ) MyLogin ( unsigned long int *pSlotID,LPTSTR pName,
// file name or for boot code: the data unsigned char * pData, // The data (if applicable) int dataLen, // dataLen (if applicable) unsigned long int userType,LPTSTR pPin,
unsigned long int ulPinLen, unsigned long int sessionFlags, // we may need RW_SESSION flag here.. unsigned long int * pSession,TOKEN_CONTEXT * pTokenContext)
//struct--------------------------------------------------------------------------------------------------------------------------
typedef
struct TOKEN_CONTEXT { int phase; unsigned long int hSession;HINSTANCE hDLL;
unsigned long int slotID;CK_FUNCTION_LIST_PTR pFunc;
// function list obtained from DLL (pointing to what we are using now) unsigned char DLLName[MAX_PATH]; unsigned char DLLPath[MAX_PATH]; unsigned char TokenName[MAX_PATH];CK_SLOT_INFO SlotInfo;
// struct unsigned long int hSessionCallback; unsigned char hashedPIN[HASH_SIZE];SC_CONFIG_STRU ConfigStru;
//struct} TOKEN_CONTEXT;
-----------------------------------------------------------------------------------------------------------------
the following is my code in my C# program, I didn't finish it, I didn't know how to continue.
[
DllImport("mfcdll.dll", EntryPoint = "MyLogin", ExactSpelling = false, CallingConvention = CallingConvention.Cdecl, SetLastError=true)] static extern int MyLogin ( CK_SLOT_ID *pSlotID,LPTSTR pName,
byte pData, int dataLen, UInt32 userType,LPTSTR pPin,
UInt32 ulPinLen, UInt32 sessionFlags, UInt32 pSession,TOKEN_CONTEXT * pTokenContext);
How can I call C function in VC#2005? Please do me a favour, for example

You want to use a C++/CLI dll here, and reference the dll in your C# application.
C++/CLI allows you to mix native and managed code.
Here is an example, using MessageBeep()
C++/CLI code, mixed native and managed
#include "windows.h"< xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
using namespace System;
using namespace System::Runtime::InteropServices;
public ref struct Beep
{
enum struct BeepTypes : unsigned int
{
Beep = (unsigned int) -1,
Asterix = MB_ICONASTERISK,
Exclamation = MB_ICONEXCLAMATION,
Hand = MB_ICONHAND,
Question = MB_ICONQUESTION,
OK = MB_OK,
};
static void MessageBeep(enum class BeepTypes beep)
{
::MessageBeep((unsigned int)beep);
}
};
void main()
{
Beep::MessageBeep(Beep::BeepTypes::Exclamation);
}
We can compile and run this as follows:
C:\>cl /nologo /clr beep.cpp user32.lib
C:\>beep
And here is the C# code that calls it:class Test
{
public static void < xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Main ()
{
Beep.MessageBeep(Beep.BeepTypes.Exclamation);
}
}
C:\>csc /nologo /r:beep.dll test.cs
C:\>test
