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.

Com example (3) -- Component code This article focuses on this series of articles. The interfaces previously designed are only auxiliary, and have nothing to do with the com thread model. Because the imodule and imodulesite interfaces implemented by the customer and components are packaged with interface transmission, the interface packaging function of MFC is used for implementation. Therefore, all inter
Lifetime of processing COM objects When an object is created, the system allocates the required memory resources. When the object is no longer needed, the object should be destroyed so that the system can use the memory resources for other purposes. In C ++, you can use new and delete to directly control the lifetime of an object. However, the COM object cannot be directly created or destroyed. The reason i
