Technical Field
The present invention relates to the field of computer technologies, and in particular, to a method and apparatus for interaction between a service program and an interface program, an electronic device, and a computer readable medium.
Background
Starting from Vista systems, to increase the security of the system, after a user logs into the system, the service and application are run in different sessions. As shown in fig. 1, where Session 0 contains only system services, other applications run in sessions other than Session 0. Thus, interaction between the Session 0 and other sessions cannot be performed, and an information window cannot be popped up to a desktop user through a service program.
Therefore, when the service program and the interface program perform interaction (the service program starts the interface executable program through WinExec or ShellExecute, etc.), an interactive service detection prompt box is popped up, as shown in FIG. 2. If clicking "remind me later" at this time, the service program and the interface program interaction is stopped, and if clicking "view message" the interface of fig. 3 will be displayed. The windows desktop at this point is not already the original desktop, has entered into another session, and the "interactive service detection" window is always present.
The existing method has poor user experience and can not display windows like normal programs; and the user desktop is replaced and cannot perform other operations while the window is displayed, so that a great deal of inconvenience is brought to the user.
