;设置图标，注意base64字符串是png格式转化而来，一般尺寸在32x32或者16x16
TraySetIcon('HICON: ' . Base64PNG_to_HICON(Base64PNG))

Base64PNG_to_HICON(Base64PNG, height := 16) {
      size := StrLen( RTrim(Base64PNG, '=') )*3//4
      if DllCall('Crypt32\CryptStringToBinary', 'Str', Base64PNG, 'UInt', StrLen(Base64PNG), 'UInt', 1,
                                                'Ptr', buf := Buffer(size), 'UIntP', &size, 'Ptr', 0, 'Ptr', 0)
          return DllCall('CreateIconFromResourceEx', 'Ptr', buf, 'UInt', size, 'UInt', true,
                                                     'UInt', 0x30000, 'Int', height, 'Int', height, 'UInt', 0)
      return 0
}
