透過go的標準函式庫exec呼叫cmd指令時會閃彈黑窗口，為解決此問題在windows下可以用win32 API 的 WinExec。
此問題主要出現在帶有UI或無控制台的程式呼叫cmd時。
編譯go時加入參數：
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
