參數

progID
String

要取得之類型的 ProgID。The ProgID of the type to get.

傳回

如果 progID 在登錄中是有效項目,而且有類型與它相關聯,則為與指定的 ProgID 相關聯的類型,否則為 nullThe type associated with the specified ProgID, if progID is a valid entry in the registry and a type is associated with it; otherwise, null.

throwOnError
Boolean

true ,擲回任何會發生的例外狀況。true to throw any exception that occurs.

-或--or- false 則忽略任何會發生的例外狀況。false to ignore any exception that occurs.

傳回

如果 progID 在登錄中是有效的項目,且有與其相關聯的類型,則為與指定的程式識別項 (progID) 相關聯的類型,否則為 nullThe 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.
