using namespace System; int main() { try { // Use the ProgID HKEY_CLASSES_ROOT\DirControl.DirList.1. String^ myString1 = "DIRECT.ddPalette.3"; // Use a nonexistent ProgID WrongProgID. String^ myString2 = "WrongProgID"; // Make a call to the method to get the type information of the given ProgID. Type^ myType1 = Type::GetTypeFromProgID( myString1, true ); Console::WriteLine( "GUID for ProgID DirControl.DirList.1 is {0}.", myType1->GUID ); // Throw an exception because the ProgID is invalid and the throwOnError // parameter is set to True. Type^ myType2 = Type::GetTypeFromProgID( myString2, true ); } catch ( Exception^ e ) { Console::WriteLine( "An exception occurred." ); Console::WriteLine( "Source: {0}", e->Source ); Console::WriteLine( "Message: {0}", e->Message ); } }
