GetTypeFromProgID Method (String, String)

Type::GetTypeFromProgID Method (String, String)

Gets the type associated with the specified program identifier (progID) from the specified server, returning null if an error is encountered while loading the type.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

static Type^ GetTypeFromProgID(
	String^ progID, 
	String^ server


Type: System::String

The progID of the type to get.

Type: System::String

The server from which to load the type. If the server name is nullptr, 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, nullptr.


prodID is nullptr.

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 Program IDs are not used in Microsoft .NET Framework because they have been superseded by the concept of namespace.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()

      // 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 );
