golang development-windows system adds pop-up windows and user selection buttons

Requirements :
Golang development, a tool under Windows system, is expected to do some initialization work when starting the exe file, and the relevant operations require the user to confirm or cancel. as follows:

Solution :

package main

import (
	"fmt"
	"syscall"
	"unsafe"
)

const (
	MB_OKCANCEL = 0x00000001
	IDOK        = 1
	IDCANCEL    = 2
)

type RECT struct {
    
    
	Left, Top, Right, Bottom int32
}

var (
	user32              = syscall.MustLoadDLL("user32.dll")
	messageBoxW         = user32.MustFindProc("MessageBoxW")
	findWindowW         = user32.MustFindProc("FindWindowW")
	getForegroundWindow = user32.MustFindProc("GetForegroundWindow")
)

func MessageBox(caption, text string, style uintptr) int {
    
    
	ret, _, _ := messageBoxW.Call(0,
		uintptr(unsafe.Pointer(syscall.StringToUTF16Ptr(text))),
		uintptr(unsafe.Pointer(syscall.StringToUTF16Ptr(caption))),
		style)
	return int(ret)
}

func GetWindowRect(hwnd syscall.Handle, rect *RECT) bool {
    
    
	ret, _, _ := syscall.Syscall(findWindowW.Addr(), 2,
		uintptr(hwnd), uintptr(unsafe.Pointer(rect)), 0)
	return ret != 0
}

func GetForegroundWindow() syscall.Handle {
    
    
	ret, _, _ := getForegroundWindow.Call()
	return syscall.Handle(ret)
}

func main() {
    
    
	const (
		caption = "提示"
		text    = "是否清理旧数据并重新注册设备？"
	)
	ret := MessageBox(caption, text, MB_OKCANCEL)

	if ret == IDOK {
    
    
		fmt.Println("用户选择了确定")
		// TODO: 添加用户选择“确定”后的逻辑处理代码
	} else if ret == IDCANCEL {
    
    
		fmt.Println("用户选择了取消")
		// TODO: 添加用户选择“取消”后的逻辑处理代码
	} else {
    
    
		fmt.Println("其他选项", ret)
	}
}
