Problem using DLL

[timmay3141]

I've never tried to use DLLs for this before, so my mistake could be really stupid. Here's my code:

// above WinMain
typedef DWORD (CALLBACK* LPREGISTERSERVICEPROC)(DWORD,DWORD);


// in WinMain
HMODULE hDLL = LoadLibrary("kernel32.dll"
try
{
if(!hDLL)
throw 0;

LPREGISTERSERVICEPROC lpRegisterServiceProc =
(LPREGISTERSERVICEPROC)::GetProcAddress(hDLL, "RegisterServiceProcess"

if(!lpRegisterServiceProc)
{
DWORD dwError = GetLastError();
throw 0;
}
else
{
DWORD dwRet = lpRegisterServiceProc(GetCurrentProcessId(), 1);
}
}
catch(int nExit)
{
FreeLibrary(hDLL);
MessageBox(NULL, "Error registering process, the program will now abort.",
"Error", MB_OK | MB_ICONSTOP);
return nExit;
}

FreeLibrary(hDLL);

The dll loads correctly, but GetProcAddress() fails. GetLastError() returns 127, which is ERROR_PROC_NOT_FOUND. This is strange, because I think I'm doing exactly what MSDN said:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/win9x/95func_3t0z.asp

What's my mistake?

Are you sure that RegisterServiceProcess() is an exported function in kernel32.dll ?

On my system (XP) it is not (Can't find it in MSDN either).

Did you check out that link? It said:

To call RegisterServiceProcess, retrieve a function pointer using GetProcAddress on KERNEL32.DLL. Use the function pointer to call RegisterServiceProcess.

It says it's in kernel32.dll, but my program doesn't seem to think so...

Oh .. it is win 9x only function.

What system do you use ?

Not sure...I use XP Pro have the latest Platform SDK if thats what you mean.

 

[JOLESEN]

Well, the function only exist on Win 9x operating systems - That is it won't work on your XP.

Oh, I see. I didn't know what Win 9x meant, that's my problem.
