这个是控制台程序，编译通不过，不知道原因

#include "stdafx.h"
#include <atlconv.h>

int main(int argc, char* argv[])
{
CoInitialize ( NULL );
hr = CoCreateInstance ( CLSID_ActiveDesktop,
NULL,
CLSCTX_INPROC_SERVER,
IID_IActiveDesktop,
(void**) &pIAD );

if ( SUCCEEDED(hr) )
{
hr = pIAD->GetWallpaper ( wszWallpaper, MAX_PATH, 0 );

if ( SUCCEEDED(hr) )
wcout << L"Wallpaper path is:\n " << wszWallpaper << endl << endl;
else
cout << _T("GetWallpaper() failed.") << endl << endl;

pIAD->Release();
}
else
cout << _T("CoCreateInstance() failed.") << endl << endl;

CoUninitialize();

return 0;
}

报错如下：
c:\program files\microsoft visual studio\vc98\atl\include\atlconv.h(46) : error C2146: syntax error : missing ';' before identifier 'WINAPI'
c:\program files\microsoft visual studio\vc98\atl\include\atlconv.h(46) : error C2433: 'LPWSTR' : 'inline' not permitted on data declarations

下面的程序调适通过

#include "stdafx.h" 
#include "iostream"
using namespace std;
#include <atlconv.h> 
#include <wininet.h> // definisce alcuni flag usati da ActiveDesktop e ShellLink
#include <shlobj.h> // definizioni principali per l'uso di ActiveDesktop e ShellLink

//struct __declspec(uuid("F490EB00-1240-11D1-9888-006097DEACF9")) IActiveDesktop;

int main(int argc, char* argv[]) 
{ 
	IActiveDesktop * pIAD = NULL;
	WCHAR wszWallpaper[ MAX_PATH ] = { 0 };
	CoInitialize ( NULL );  
	HRESULT hr = CoCreateInstance ( CLSID_ActiveDesktop, 
		NULL, 
		CLSCTX_INPROC_SERVER, 
		IID_IActiveDesktop, 
		(void**) &pIAD ); 

	if ( SUCCEEDED(hr) ) 
	{ 
		hr = pIAD->GetWallpaper ( wszWallpaper, MAX_PATH, 0 ); 

		if ( SUCCEEDED(hr) ) 
			wcout << L"Wallpaper path is:\n    " << wszWallpaper << endl << endl; 
		else 
			cout << _T("GetWallpaper() failed.") << endl << endl; 

		pIAD->Release(); 
	} 
	else 
		cout << _T("CoCreateInstance() failed.") << endl << endl; 

	CoUninitialize(); 

	return 0; 
}

你这个错误都是在atlconv.h这里面的。
不知道这面都写了些什么。
