VC 如何调用应用程序?

[dg393624170]

问题：

开机自动运行的服务程序（无界面）中，调用一个应用程序（XXX.exe）？

如果可以的话，给个函数吧？

如果你只想在开机后启动这个exe，完全不用这么坐，可以往系统启动项的注册表写值，还可以将exe的快捷方式直接加到startup文件夹下就OK了。
如果你非要用程序去掉，连个函数，很简单CreateProcess和ShellExecute，建议用CreateProcess。

很简单CreateProcess和ShellExecute，建议用CreateProcess在服务程序中应该是掉不起来吧，老兄

汗。。。。。。

很多方法可以实现，ShellExecute比较方便，

给个例子吧。。。求求各位了

那个英文看的人头大啊。。。。。。。。。

这是MFC的一段话：

Interactive Services
An interactive service is a service that can interact with the input desktop. Other desktops do not receive user input. For more information, see Window Stations and Desktops.

An interactive service must run in the context of the LocalSystem account and be configured to run interactively. Services are configured to run interactively when the dwServiceType parameter in a CreateService call is set to include SERVICE_INTERACTIVE_PROCESS.

意思是说你可以创建一个交互型服务程序，这样就可以与桌面交互了。
方法：通过创建服务函数CreateService（） 的一个参数dwServiceType，把它的值设为SERVICE_INTERACTIVE_PROCESS。
然后启动你要进程，用我上面的ShellExecute或CreateProcess。

ShellExecute就可以了吧，方便实用

CreateProcess

[c_losed]

system
winexec
CreateProcess
ShellExecute
...

服务调用用户进程，需要模拟当前用户token等，然后CreateProcessAsUser
否则进程会启动在服务session，不可见

好像就是这么用的

可不可以给个例子啊。。。。。。。

提供一段代码，大家帮我解释下，谢谢？？
可不可以使用传一个静安装参数？

楼主那个服务是SERVICE_INTERACTIVE_PROCESS类型的吗？可以用ShellExecute或CreateProcess调用应用程序呀
