Question

I’m trying to implement IInternetZoneManager in .NET with Webbrowser Control but I have no clue what to do.

I couldn’t find any managed code example about this implementation. I’m pretty bad about OLE stuff.

Can anyone provide a sample on this? I spend about 2 days with no luck.

Answer 1

This is what I get when I convert it:

public class Constants {     public const int MAX_PATH = 260;     public const int MAX_ZONE_PATH = 260;     public const int MAX_ZONE_DESCRIPTION = 200; }  [StructLayout(LayoutKind.Sequential, CharSet=CharSet.Unicode)] public struct ZONEATTRIBUTES {     public uint cbSize;     [MarshalAs(UnmanagedType.ByValTStr, SizeConst = Constants.MAX_PATH)]     public string szDizplayName;     [MarshalAs(UnmanagedType.ByValTStr, SizeConst = Constants.MAX_ZONE_DESCRIPTION)]     public string szDescription;     [MarshalAs(UnmanagedType.ByValTStr, SizeConst = Constants.MAX_PATH)]     public string szIconPath;     public uint dwTemplateMinLevel;     public uint dwTemplateRecommended;     public uint dwTemplateCurrentLevel;     public uint dwFlags; }  public enum URLZONEREG {     URLZONEREG_DEFAULT = 0,     URLZONEREG_HKLM,     URLZONEREG_HKCU }  [Guid('79eac9ef-baf9-11ce-8c82-00aa004ba90b')] [ComImport] public interface IInternetZoneManager {     void CopyTemplatePoliciesToZone(uint dwTemplate, uint dwZone, uint dwReserved);     void CreateZoneEnumerator(ref uint pdwEnum, ref uint pdwCount, uint dwFlags);     void DestroyZoneEnumerator(uint dwEnum);     void GetZoneActionPolicy(uint dwZone, uint dwAction, IntPtr pPolicy, uint cbPolicy,          URLZONEREG urlZoneReg);     void GetZoneAt(uint dwEnum, uint dwIndex, ref uint pdwZone);     void GetZoneAttributes(uint dwZone, ref ZONEATTRIBUTES pZoneAttributes);     void GetZoneCustomPolicy(uint dwZone, [In] ref Guid guidKey, ref IntPtr ppPolicy,         ref uint pcbPolicy, URLZONEREG urlZoneReg);     void LogAction(uint dwAction, [MarshalAs(UnmanagedType.LPWStr)] string pwszUrl,          [MarshalAs(UnmanagedType.LPWStr)] string pwszText, uint dwLogFlags);     void PromptAction(uint dwAction, IntPtr hwndParent, [MarshalAs(UnmanagedType.LPWStr)] string pwszUrl,         [MarshalAs(UnmanagedType.LPWStr)] string pwszText, uint dwPromptFlags);     void SetZoneActionPolicy(uint dwZone, uint dwAction, IntPtr pPolicy, uint cbPolicy,         URLZONEREG urlZoneReg);     void SetZoneAttributes(uint dwZone, ref ZONEATTRIBUTES pZoneAttributes);     void SetZoneCustomPolicy(uint dwZone, [In] ref Guid guidKey, IntPtr pPolicy,         uint pcbPolicy, URLZONEREG urlZoneReg); } 

I’ve also posted the definition at pinvoke.net:

Generally, you should look there first for interop definitions (and contribute if it’s not there).
