There are few examples of searching com aggregation on the Internet, either using ATL, simulating ATL, or simulating MFC. Most of them are based on principles. Since the process for querying the iunknown interface is different when you simulate MFC and when you actually use MFC, the method for simulating MFC is different from that for directly deriving from csf-target, there are major differences in the process. Even if you understand the principle of

First verify that the. Net Framework 1.1 is installed on Windows (the server side of the SQL Server, of course)!
Confirm after successful installation:
1. Create a strong-name key file for the class library using Sn-k:

Problem:
Im trying to implement mapview example which is defined on Android Hello views example but now Im facing failed to find provider info for com. Google. settings error...
Solution:
The mapview example doesn't set API key by default. So you must set it. Here is step by step:

For such leaks, VC ide will be powerless, because it is only good at matching new and delete.

and load balancing for websocket programs.Nginx ConfigurationNote: See official documents said Nginx in the version after 1.3 only support websocket reverse proxy, so to use the support WebSocket features, you must upgrade to 1.3 later versionNginx supports websocket by allowing a tunnel to be established between the client and the back-end server. The upgrade and connection headers must be set explicitly in order for Nginx to send the client upgrade
This article mainly describes how to capture the IP address of a proxy server using multiple Python threads. despite the existence of GIL, Python cannot truly implement multi-thread parallel processing, A friend can refer to here to capture the http://www.proxy.com.ru site proxy server as an example, the code is as follows:

Nginx Configuration Note: See official documents said Nginx after 1.3 version of the support WebSocket reverse proxy, so to use the support WebSocket features, you must upgrade to 1.3 Future
