Recently in the resolution of the problem had to use the thread, so as to contact the STA and MTA, degrees Niang interpretation mostly vague. Read more clearly on Wikipedia, taking advantage of the easy-to-access gap between sharing and self-improvement.
Apartment Type
Description
single-threaded Apartment (STA), (threadingmodel=Apartment)
A Single thread was dedicated to execute the methods of the object. In such
multithreading in ArcGIS Engine.
This means that all Ao items should be put in one thread to work, and ao com components cannot be used across threads.
Okay, I'm speechless, and there's no solution to this problem .. I really don't understand why it is limited to a thread.
As in the last article, leave a message:
Well written. I recently encountered the problem of multithreading in the Development of AE, which has not been solved. Finally, give up and return to the single-thread developm

This memory structure will have one for each thread. A COM object that supports STA can only be used in the line thread that created it, and other threads will fail if it is created again.Mta:mutil-thread Apartment, Chinese call
Email Service
The email service is based on the customer/server model. For a complete email system, it consists of three components.
1. The user agent interface between the user and the email system is responsible for sending emails to the mail server and receiving emails from the mail server.

2. the email server is the core component of the email system.

MTA (Mail transfer Agent)-For server administrators, the message transfer agent is the most important tool. The main task of the MTA is to send e-mail messages from one host to another host. The MTA uses SMTP (Simple Mail Transfer Protocol) to deliver e-mail messages. To make it clearer to you, the clients we use to send and receive mail are also using SMTP, but

As operational processes become more flexible, it teams are faced with ever-greater complexity. When applications change dynamically, agile or continuous application development can be used. But what happens when the IT resources themselves change dynamically? Cloudy and hybrid clouds are part of this new, dynamic it landscape – and they pose a fresh risk. To solve the problem here, some enterprises use the infrastructure as the code schema. Configura

The Internet has undergone dramatic changes over the past decade. However, in the enterprise data center, the changes are not very big. IT administrators still need to spend time managing the "island-style" IT systems, and the deployment and configuration of IT infrastructure is still relatively difficult, in addition, the energy consumption continues to rise. As a result, Converged Infrastructure (CI) has

The immutable infrastructure (immutable Infrastructure) is a very predictive concept proposed by Chad Fowler in 2013, and its core idea is that instances of any infrastructure become read-only once created, such as modifications and upgrades, is replaced with a new instance.

Infrastructure is important to data centers, just as drainage systems are important to urban construction. There are plenty of tall buildings on the city floor, the surface of the city will disappear.
So how can we pay attention to infrastructure to avoid data centers from losses in the event of storms? Infrastructure is a concealed project and a project that req

How to plan the infrastructure capacity?
Follow the following guidelines to expand data center availability to avoid space waste or even capacity shortage.
This is almost impossible, but someone still needs to do it: predict the space, power, and cooling needs of the data center in the future. This task is very difficult, and the emergence of cloud computing makes infrastructure planning more difficult.
