LoadLibrary return..

Hi ppl, i'm new here and this is my first post.

I got this code and it works fine! It just set "myprinter" as default printer.

Code:

HINSTANCE lib;
	lib = LoadLibrary("printui.dll");
	if ( lib == NULL ) {
		printf("%s\n", "printui.dll");
		return 0;
	}
	LPFUNC PrintUIEntry;
	PrintUIEntry = (LPFUNC)GetProcAddress(lib, "PrintUIEntryW");
	if ( PrintUIEntry == NULL ) {
		FreeLibrary( lib );
		printf("%s\n", "PrintUIEntry");
		return 0;
	}
	_bstr_t bstrParam;
	bstrParam = " /y /n \"myprinter\"";

	PrintUIEntry(
		GetDesktopWindow(),
		lib,
		(wchar_t *)bstrParam,
		SW_SHOW
	);
	
	FreeLibrary( lib );

But i need to know if it worked. I need an exit code, or boolean response.

Someone knows how to retrieve it?

I can't find the function PrintUIEntry at MSDN, but I'd expect it to return something, so check for return after calling your function pointer.

T ret = PrintUIEntry(
GetDesktopWindow(),
lib,
(wchar_t *)bstrParam,
SW_SHOW
);

I can't find either. But I solved it this morning.
I missed a part of my code:

typedef void (__stdcall *LPFUNC)
(
HWND hwnd,
HINSTANCE hinst,
LPWSTR lpszCmdLine,
int nCmdShow
);

Well, a void will never return any value, right?

then... I changed:

typedef int (__stdcall *LPFUNC)
(
HWND hwnd,
HINSTANCE hinst,
LPWSTR lpszCmdLine,
int nCmdShow
);

And, works fine:

int ret = PrintUIEntry(
GetDesktopWindow(),
lib,
(wchar_t *)bstrParam,
SW_SHOW
);

Sorry about my mistake.

Tks for your help!
