public static Type GetTypeFromProgID ( String progID, String server )
public static function GetTypeFromProgID ( progID : String, server : String ) : Type
Parameters
- progID
The progID of the type to get.
- server
The server from which to load the type. If the server name is a null reference (Nothing in Visual Basic), this method automatically reverts to the local machine.
Return Value
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, a null reference (Nothing in Visual Basic).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 ); } }
