Go语言MessageBox用法实例

       MB_ICONSTOP                = MB_ICONHAND
       MB_DEFBUTTON1              = 0x00000000
       MB_DEFBUTTON2              = 0x00000100
       MB_DEFBUTTON3              = 0x00000200
       MB_DEFBUTTON4              = 0x00000300
)
func MessageBox(caption, text string, style uintptr) (result int) {
       // var hwnd HWND
       ret, _, callErr := syscall.Syscall6(uintptr(messageBox), 4,
               0, // HWND
               uintptr(unsafe.Pointer(syscall.StringToUTF16Ptr(text))), // Text
               uintptr(unsafe.Pointer(syscall.StringToUTF16Ptr(caption))), // Caption
               style, // type
               0,
               0)
       if callErr != 0 {
               abort("Call MessageBox", int(callErr))
       }
       result = int(ret)
       return
}
func main() {
       defer syscall.FreeLibrary(kernel32)
       defer syscall.FreeLibrary(user32)
       fmt.Printf("Retern: %dn", MessageBox("Done Title", "This test is Done.", MB_YESNOCANCEL))
}
func init() {
       fmt.Print("Starting Upn")
}
