since VB -String = VC-BSTR
so you can try .....

typedef int (WINAPI *MYPROC)(BSTR, BSTR)

use typedef int _stdcall (*MYPROC)(LPTSTR, LPTSTR)

the prorblem has to do with who is responsible for cleaning up the stack.

Interprocess Communication is use to communicate between two or more process (based on method you are using). Now let if you Window Service have window it must have HWND associated with it... so using Simplest Interprocess mechanism i.e. Window Message you can Post your User Defined messages (WM_APP+ and WM_USER+) with some other program/process and instruct the service to work according to it...

This is just simple logic. Better you try this logic with two desktop-based application before applying directly to service.

Yeap service don't have any FrontEnd, but you can have both Windows and front end for service....( clue: desktop interactice service)

Definitely, no.
Definitely, yes - if you can access information on the Kernel internal structures. But even if so, your app may not work on different Windows versions.

Even if he had kernel access he couldn't!
The kernel does not use handles for the process. It uses pointers to EPROCESS structures!

how to get IMAGE_FUNCTION_ENTRY

I know that I can make a driver and use deviceiocontrol and get the handle out but just tell me the function.
The EPROCESS structure doesn't have a member for the handle.

I know about this function
NTSYSAPI
NTSTATUS
NTAPI
PsLookupProcessByProcessId (
    IN ULONG        ProcessId,
    OUT PEPROCESS       *Process
);
and this is all I know about eprocess

typedef struct _EPROCESS {
    KPROCESS            Pcb;
    EX_PUSH_LOCK        ProcessLock;
    ...

    UCHAR               ImageFileName[16];
    ...

    UCHAR               PriorityClass;
    BOOLEAN             WorkingSetAcquiredUnsafe;
} EPROCESS, *PEPROCESS;

is KPROCESS the process HANDLE and if it is what ACCESS does it have, i supose PROCESS_ALL_ACCESS right ??/

i wonder how can I get an IMAGE_FUNCTION_ENTRY of a certain function in a dll
is it
IMAGE_FUNCTION_ENTRY *IFE=(IMAGE_FUNCTION_ENTRY *)((BYTE *)hMod+FunctionAddress) ????
this returns a non NULL value but I am not sure if it is a valid structure

It is definitly not.
The code you are using may not even create a pointer to valid memory.
Read the "SymFunctionTableAccess64" page in MSDN and you will see that IMAGE_FUNCTION_ENTRY is not used on x86 (Intel + AMD) platforms.

Newbie Question

I'm trying to teach myself C++. I making a real simple calculator (console app) from an exercise in a book. It needs to display, "Press any key to continue".
I declared a variable chKey, but when I hit enter the cursor just keeps moving down the command prompt.

cout << "PRESS ANY KEY TO CONTINUE\n\n";
cin >> chKey;

Is there anything I need to do to "continue"? The book is no help.

Thanks

Try this instead:

cout << "PRESS ANY KEY TO CONTINUE" << endl << endl;
getch();
