c语言调用cmd隐藏黑窗口,golang 调用cmd下程序隐藏黑窗口-方法1

通过go的标准库exec调用cmd命令时会闪弹黑窗口，为解决此问题在windows下可以用win32 API 的 WinExec。

此问题主要出现在带UI或无控制台的程序调用cmd时。

编译go时加入参数： go build  -ldflags="-H windowsgui"

package main

import (

"errors"

"log"

)

import (

"github.com/CodyGuo/win"

)

var (

winExecError = map[uint32]string{

0: "The system is out of memory or resources.",

2: "The .exe file is invalid.",

3: "The specified file was not found.",

11: "The specified path was not found.",

}

)

func main() {

err := execRun("cmd /c start http://www.baidu.com")

if err != nil {

log.Fatal(err)

}

}

func execRun(cmd string) error {

lpCmdLine := win.StringToBytePtr(cmd)

// http://baike.baidu.com/link?url=51sQomXsIt6OlYEAV74YZ0JkHDd2GbmzXcKj_4H1R4ILXvQNf3MXIscKnAkSR93e7Fyns4iTmSatDycEbHrXzq

ret := win.WinExec(lpCmdLine, win.SW_HIDE)

if ret <= 31 {

return errors.New(winExecError[ret])

}

return nil

}
