Win32 API的运行.exe文件等 [英] win32 API for running other .exe
本文介绍了Win32 API的运行.exe文件等的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想知道在Win32 API运行 REGSVR32 编程。
I wanted to know the win32 API to run the regsvr32 programatically.
我有一个应用程序，通过它我可以用COM口设备进行通信，但要实现通信，我必须注册 MSCOMM32.OCX 使用 REGSVR32 .EXE 。
I have one application through which I can communicate with COM port devices, but to achieve communication, I have to register MSCOMM32.ocx using regsvr32.exe.
但现在我想补充这一规定在我的code，所以没有必要跑 regsvr 手动
But now I wanted to add this provision in my code, so that there is no need to run regsvr manually.
