@msdn=http://search.microsoft.com/search/results.aspx?qu=$$$ @pinvoke=http://pinvoke.net/$$$.htm Summary: The HttpDeleteServiceConfiguration function deletes specified information, such as IP addresses or SSL Certificates, from the HTTP API configuration store, one record at a time. !!!!C# Signature: [DllImport("httpapi.dll", SetLastError = true)] static extern uint HttpDeleteServiceConfiguration( IntPtr ServiceIntPtr, HTTP_SERVICE_CONFIG_ID ConfigId, IntPtr pConfigInformation, int ConfigInformationLength, IntPtr pOverlapped); !!!!VB Signature: Declare Function HttpDeleteServiceConfiguration Lib "httpapi.dll" (TODO) As TODO !!!!User-Defined Types: [HTTP_SERVICE_CONFIG_ID] [HTTP_SERVICE_CONFIG_IP_LISTEN_PARAM] [HTTP_SERVICE_CONFIG_SSL_KEY] [HTTP_SERVICE_CONFIG_URLACL_SET] !!!!Notes: Depending on the value of ConfigId, pConfigInformation should point to a different type of structure. If it wasn't for this, I could redifine the PInvoke signature to explicitly specify the underlying structure type. ||'''ConfigId Value'''||'''ConfigInformation Structure Type'''|| ||HttpServiceConfigIPListenList||[HTTP_SERVICE_CONFIG_IP_LISTEN_PARAM] structure.|| ||HttpServiceConfigSSLCertInfo||[HTTP_SERVICE_CONFIG_SSL_KEY] structure.|| ||HttpServiceConfigUrlAclInfo||[HTTP_SERVICE_CONFIG_URLACL_SET] structure.|| !!!!Tips & Tricks: If your use of this API is focused around a single value of ConfigId, you may want to change the IntPtr (pConfigInformation) to point directly to a managed version of the correct underlying structure and let the default marshaller take care of the interop layer marshaling for you (and your memory management). !!!!Sample Code: void FreeURL(string networkURL, string securityDescriptor) { uint retVal = (uint) ErrorCodes.NOERROR; retVal = HttpApi.HttpInitialize(HttpApi.HTTPAPI_VERSION, HttpApi.HTTP_INITIALIZE_CONFIG, IntPtr.Zero); if ((uint) ErrorCodes.NOERROR == retVal) { HTTP_SERVICE_CONFIG_URLACL_KEY urlAclKey = new HTTP_SERVICE_CONFIG_URLACL_KEY(networkURL); HTTP_SERVICE_CONFIG_URLACL_PARAM urlAclParam = new HTTP_SERVICE_CONFIG_URLACL_PARAM(securityDescriptor); HTTP_SERVICE_CONFIG_URLACL_SET urlAclSet = new HTTP_SERVICE_CONFIG_URLACL_SET(); urlAclSet.KeyDesc = urlAclKey; urlAclSet.ParamDesc = urlAclParam; IntPtr configInformation = Marshal.AllocCoTaskMem(Marshal.SizeOf(typeof(HTTP_SERVICE_CONFIG_URLACL_SET))); Marshal.StructureToPtr(urlAclSet, configInformation, false); int configInformationSize = Marshal.SizeOf(urlAclSet); retVal = HttpApi.HttpDeleteServiceConfiguration(IntPtr.Zero, HTTP_SERVICE_CONFIG_ID.HttpServiceConfigUrlAclInfo, configInformation, configInformationSize, IntPtr.Zero); Marshal.FreeCoTaskMem(configInformation); HttpApi.HttpTerminate(HttpApi.HTTP_INITIALIZE_CONFIG, IntPtr.Zero); } if ((uint) ErrorCodes.NOERROR != retVal) { throw new Win32Exception(Convert.ToInt32(retVal)); } } !!!!Alternative Managed API: Do you know one?
