IFtpProviderConstruct Interface

IIS 7.0

Provides an interface for passing configuration settings to a provider.

interface IFtpProviderConstruct : IUknown

The following table lists the methods exposed by the IFtpRoleProvider interface.



IFtpProviderConstruct::Construct Method

Retrieves an array of key/value pairs from an FTP provider's configuration settings in the IIS ApplicationHost.config file.

You can specify parameters for an FTP provider in the IIS ApplicationHost.config file by adding an <activation> collection, which may contain a series of <providerData> elements that list additional settings for custom FTP providers. Each <providerData> element is paired with an entry in the <providerDefinitions> collection, and contains a series of key/value pairs that contain information that is specific to each provider.

The following configuration excerpt illustrates a custom FTP provider entry in the ApplicationHost.config file and its related information.

      <add name="FtpDemo"
         clsid="FtpDemo.DemoProvider" />
         <providerData name="FtpDemo">
            <add key="one" value="1" />
            <add key="two" value="2" />


The following code example iterates through the array of configuration settings and sends the key/value pairs to the debug stream.

   STDMETHOD(Construct)(SAFEARRAY * configurationEntries)
      HRESULT hr = S_OK;
      LONG lLbound = 0;
      LONG lUbound = 0;


      // Retrieve the upper and lower bounds for the configuration array.
      SafeArrayGetLBound( configurationEntries, 1, &lLbound );
      SafeArrayGetUBound( configurationEntries, 1, &lUbound );

      // Retrieve a pointer to the array of configuration settings.
      hr = SafeArrayAccessData(configurationEntries, (void**)&pArray);
      // Return an error if a failure occurs.
      if (FAILED(hr))
         return hr;

      // Loop through the array of configuration setttings and
      // output the key/value pairs to the debug channel.
      for(LONG Index = lLbound; Index <= lUbound; Index ++)

      // Release the pointer to the array of configuration settings.
      hr = SafeArrayUnaccessData(configurationEntries);
      // Return an error if a failure occurs.
      if (FAILED(hr))
         return hr;

      return S_OK;
