SQL Server's T-SQL programming language is powerful in data storage and recovery, but is less functional in terms of interacting with systems outside of the SQL Server database. However, we can overcome this limitation with SQL Server's built-in COM automation environment, which enables users to automate COM objects in stored procedures. With 7 extended stored procedures in SQL Server 7.0 and SQL Server 6.

The distinction between components (Component) and objects (object) is defined first:A component is a reusable module that is a business object (Rules object) that consists of a set of processes, data encapsulation, and user interfaces. The component looks like an object, but does not conform to the academic definition of the object.The main differences are:1) A component can be used in another application called a container (sometimes referred to as a bearer or host) or as an independent proces

First of all, this test is not successful, it is only feasible on this machine, and the test fails on different machines. The GUID may be incorrect or not registered successfully.Now that we've spent the whole morning studying, I'm going to summarize1. Online said to create an SNK certificate, but not created or can.

Query informationOne of the main functions of WMI is to query the WMI repository for information about classes and instances, we can call a synchronous query, or we can call an asynchronous query. A synchronous query is a query that executes at the current execution, and an asynchronous query needs to start another thread to query, and after the query has finished, call the defined interface (similar to a callback function) to handle the query results. Synchronous query is suitable for querying

Startup Failure Reason Once the Window service program is started, a run method is called in the WinMain method Collapsehresult Run (_in_ int nshowcmd = sw_hide) throw () { HRESULT hr = S_OK; t* PT = static_cast The Run method calls the Pt->runmessageloop () method for a while loop, which prevents the WinMain method from returning, causing the program to end.
