Type.GetTypeFromProgID Method (String, String, Boolean)
Assembly: mscorlib (in mscorlib.dll)
public: static Type^ GetTypeFromProgID ( String^ progID, String^ server, bool throwOnError )
public static Type GetTypeFromProgID ( String progID, String server, boolean throwOnError )
public static function GetTypeFromProgID ( progID : String, server : String, throwOnError : boolean ) : 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.
- throwOnError
true to throw any exception that occurs.
-or-
false to ignore any exception that occurs.
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, specifying whether to throw an exception if the ProgID or the server name is invalid.
using namespace System; int main() { try { // Use server localhost. String^ theServer = "localhost"; // Use ProgID HKEY_CLASSES_ROOT\DirControl.DirList.1. String^ myString1 = "DirControl.DirList.1"; // Use a wrong ProgID WrongProgID. String^ myString2 = "WrongProgID"; // Make a call to the method to get the type information for the given ProgID. Type^ myType1 = Type::GetTypeFromProgID( myString1, theServer, 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, theServer, true ); } catch ( Exception^ e ) { Console::WriteLine( "An exception occurred. The ProgID is wrong." ); Console::WriteLine( "Source: {0}", e->Source ); Console::WriteLine( "Message: {0}", e->Message ); } }
