如何使用Createprocessa（）在C ++中运行批处理文件 [英] How Can I Run Batch File With Createprocessa() In C++

问题描述

我想用createprocessA（）运行命令行批处理文件。

因为我想运行cmd行而不可见。

我必须隐藏cmd窗口。

这是我的代码：

I want run command line batch file with createprocessA().
Because I want run cmd line without visible.
I have to hide cmd window.
Here is my code:

PROCESS_INFORMATION pInfo;
	FillMemory(&pInfo, sizeof(PROCESS_INFORMATION), 0); 
	STARTUPINFOA sInfo;
	FillMemory(&sInfo, sizeof(STARTUPINFOA), 0); 
	sInfo.cb = sizeof(STARTUPINFOA);
	sInfo.lpReserved = NULL;
	sInfo.lpReserved2 = NULL;
	sInfo.cbReserved2 = 0;
	sInfo.lpDesktop = NULL;
	sInfo.lpTitle = NULL;
	sInfo.dwFlags = STARTF_USESTDHANDLES | STARTF_USESHOWWINDOW;
	sInfo.hStdInput = GetStdHandle(STD_INPUT_HANDLE);
	sInfo.hStdOutput =  GetStdHandle(STD_OUTPUT_HANDLE);
	sInfo.hStdError = GetStdHandle(STD_ERROR_HANDLE);
	sInfo.wShowWindow = SW_HIDE;
	BOOL ret = ::CreateProcessA("c:\\windows\\system32\\cmd.exe", "c:\\windows\\shot.bat", NULL, NULL, FALSE, 0, NULL, NULL, &sInfo, &pInfo);

我在这样的cmd窗口试过它。

cmd /cc:\\windows\\shot.bat

效果不错但是。

CreateProcessA（）返回1并且不执行批处理文件操作。

它不起作用。





我需要帮助。

I tried it in cmd window like this.
cmd /c c:\\windows\\shot.bat
It works well but.
CreateProcessA() returns 1 and it does not take batch file action.
It does not work.


I need help.

我已经使用批处理文件进行了测试，并且完全按照描述工作。

This article is exactly what you want;

Running console applications silently[^]

I have tested with batch file and works exactly as described.

您需要使用 / c 或 / k ;使用这些选项后面的文本作为启动的shell中的命令执行。

You need to use either /c or /k; using these options the text behind it executed as a command in the shell that is started.

引用cmd /？：

启动Windows命令解释程序的新实例



CMD [/ A | / U] [/ Q] [/ D] [/ E：ON | / E：OFF] [/ F：ON | / F：OFF] [/ V：ON | / V：OFF]

[[/ S] [/ C | / K] string]



/ C执行string指定的命令然后终止

/ K执行string指定的命令但仍然是

Starts a new instance of the Windows command interpreter

CMD [/A | /U] [/Q] [/D] [/E:ON | /E:OFF] [/F:ON | /F:OFF] [/V:ON | /V:OFF]
[[/S] [/C | /K] string]

/C Carries out the command specified by string and then terminates
/K Carries out the command specified by string but remains
