Hi !
I am working over windows API but i am stuck with few structs of win
dll's that how can i use them using PInvoke (as i cant use Interop so i
have to go with PInvoke).
The problem is that how can i convert Windows Struct and deffinations
into C# deffinations to delcare them atleast.
Can some one reffer me any article or suggest me how to do.
Regards,
Usman Bashir
 
Hello Usman,

Your best bet is to check out www.pinvoke.net. The have a lot of the Win32
API definitions in C#. If you have specific structs you need that aren't
published there post back with those and we'll try to help you out.

Thanks Parsons!
i did check the site but unable to find the required method there too.
Actually i m working with MAPI32 and i need this method to get the list
of messages. The declaration in mapi32 and my suggested declartion is
given below;
{windows Declartion)
HRESULT HrQueryAllRows(
LPMAPITABLE ptable,
LPSPropTagArray ptaga,
LPSRestriction pres,
LPSSortOrderSet psos,
LONG crowsMax,
LPSRowSet FAR * pprows
);

(my proposed)
[DllImport("MAPI32.DLL", CharSet = CharSet.Ansi, EntryPoint =
"MAPIFreeBuffer@4")]
private static extern int HrQueryAllRows(IntPtr pTable,IntPtr
pProp,IntPtr pRest, IntPtr pSort,long wCount,IntPtr lpRows);

//But again i m not sure how to use it after getting the interface
pointer. i do have samples in C++ but surelly it become ambigous while
casting them in C#.
Thanks in advance.

If you did not find it there try looking for it in the newsgroups archives,
if you find your solution, PLEASE update pinvoke.net so the next one will
save time.
