[SecurityCriticalAttribute]
static Type^ GetTypeFromProgID(
	String^ progID,
	String^ server
)

Parameters

progID
Type: System::String^

The progID of the type to get.

server
Type: System::String^

The server from which to load the type. If the server name is null, this method automatically reverts to the local machine.

Return Value

Type: System::Type^

The type associated with the specified program identifier (progID), if progID is a valid entry in the registry and a type is associated with it; otherwise, null.

Exception Condition
ArgumentException

prodID is null.

This method is provided for COM support. Program IDs are not used in Microsoft .NET Framework because they have been superseded by the concept of namespace.

The following example retrieves a type by passing a ProgID and server name. The example then displays the ClassID related to the ProgID, or throws an exception if the ProgID or the server name is invalid.

using namespace System;
int main()
{
   try
   {

      // Use the ProgID localhost\HKEY_CLASSES_ROOT\DirControl::DirList.1.
      String^ theProgramID = "DirControl.DirList.1";

      // Use the server name localhost.
      String^ theServer = "localhost";

      // Make a call to the method to get the type information for the given ProgID.
      Type^ myType = Type::GetTypeFromProgID( theProgramID, theServer );
      if ( myType == nullptr )
      {
         throw gcnew Exception( "Invalid ProgID or Server." );
      }
      Console::WriteLine( "GUID for ProgID DirControl.DirList.1 is {0}.", myType->GUID );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "An exception occurred." );
      Console::WriteLine( "Source: {0}", e->Source );
      Console::WriteLine( "Message: {0}", e->Message );
   }

}
