[Pin to top] VC ++ creates a Windows Service

first, attach the Source Code of the Windows creation service. This is very useful and is usually used by everyone.

I used the functions in the DLL during development and used the static import method at the beginning. However, I found that the service will die after it is started. This is not a dll path problem.

No way, you have to use the dynamic import method. Fortunately, the service is automatically started and running, and it is still normal.

TIPS: If you need to bring up the MessageBox message, for example, to allow the Service to interact with the desktop. This can be set in the service.

Of course, I have set the initialization parameters here. After the installation is completed in the DOS command, you will find that the box has been selected for you.

// Important Note: it is best not to compile and execute the service directly. Although it is exe, the best way is to install it,

Install servicename.exe/install

Uninstall servicename.exe in DOS/Uninstall

Running EXE directly will not only report an error, but also cause the service to fail to run automatically when it is started.

Most of the time, if you run the EXE directly, the error 1063 is reported because you run the service in the console.
