How to hide the dos window when golang calls cmd command

When calling the cmd command through go's standard library exec, a black window will pop up. To solve this problem, you can use the win32 API WinExec under Windows.

This problem mainly occurs when a program with UI or no console calls cmd.

Add parameters when compiling go:

go build  -ldflags="-H windowsgui"
package main
import (
	"errors"
	"
)
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)

	ret := win.WinExec(lpCmdLine, win.SW_HIDE)	
	if ret <= 31 {		
	    return errors.New(winExecError[ret])
	}	return nil
}
