help me with dllcall

[sunless]

I wan't find the url in IE cache . and I found func FindFirstUrlCacheEntryEx and FindNextUrlCacheEntryEx in wininet.dll can do it . So I wan't use Dllcall to use that func. but my script is worng.

my script

$d = DllStructCreate("dword;byte")
$t = DllStructCreate("dword;byte")
$m = DllStructCreate("dword;byte")
$tt = DllCall("wininet.dll","int","FindFirstUrlCacheEntryEx", _
                                    "str","", _ 
                                    "ptr", 0,  _ 
                                    "ptr","NORMAL_CACHE_ENTRY", _
                                    "ptr", 0, _
                                    "ptr", DllStructGetPtr($res), _
                                    "ptr",DllStructGetPtr($d), _
                                    "ptr", DllStructGetPtr($t), _
                                    "ptr", DllStructGetPtr($m), _
                                    "ptr",0)

and this is the func in msdn

HANDLE FindFirstUrlCacheEntryEx(

__in LPCTSTR lpszUrlSearchPattern,

__in DWORD dwFlags,

__in DWORD dwFilter,

__in GROUPID GroupId,

__out LPINTERNET_CACHE_ENTRY_INFO lpFirstCacheEntryInfo,

__inout LPDWORD lpdwEntryInfo,

__out LPVOID lpGroupAttributes,

__inout LPDWORD lpcbGroupAttributes,

__in LPVOID lpReserved

);

and msdn url http://msdn2.microsoft.com/en-us/library/a...034(VS.85).aspx

BOOL FindNextUrlCacheEntryEx(

__in HANDLE hEnumHandle,

__inout LPINTERNET_CACHE_ENTRY_INFO lpNextCacheEntryInfo,

__inout LPDWORD lpcbEntryInfo,

LPVOID lpGroupAttributes,

LPDWORD lpcbGroupAttributes,

LPVOID lpReserved

);

and http://msdn2.microsoft.com/en-us/library/a...057(VS.85).aspx
