在GUI测试过程中，通常会碰到对象无法被测试工具识别的问题，这时候往往需要特殊的解决办法，其中一种方法就是通过发送键盘按键的方式来操纵控件。
下面以QQ2009正式版为例，介绍使用Type和Mercury.DeviceReplay对象处理控件的方法。
以下是录制的脚本：
Window("QQ2009 正式版").Activate
Window("QQ2009 正式版").WinObject("123456").Click 46,11
Window("QQ2009 正式版").WinObject("123456").Type "123456"
Window("QQ安全中心").Activate
Window("QQ安全中心").Click 369,302
可以看到密码输入的步骤没有录制下来，按下登录按钮的步骤也没有录制下来。在对象库手工添加对象后再录制，仍然没有把密码输入的步骤录制下来，因此需要手工添加这一步的脚本（另外在对象库中也不能手工地把登录按钮对象添加进去）。调整脚本如下：
Window("QQ2009 正式版").Activate
Window("QQ2009 正式版").WinObject("123456").Click 46,11
Window("QQ2009 正式版").WinObject("123456").Type "123456"
Window("QQ2009 正式版").WinEdit("Edit").Type "123456"
' 按5次TAB键后聚焦在“登录”按钮上面
For I=1 to 5
Window("QQ2009 正式版").Type micTab
Next
Window("QQ2009 正式版").Type micReturn ' 按回车键模拟用户点击“登录”按钮
在这里使用了Window测试对象的Type方法来模拟按键，Type方法接受一个按键常量作为输入参数。
登录如果失败会出现“QQ安全中心”界面，在这个界面中“取消按钮”也没有被识别出来，因此需要采用相同的办法来处理：
If Window("QQ安全中心").Exist(10) Then ' 密码输入不正确
Window("QQ安全中心").Activate
Window("QQ安全中心").Type micTab
Window("QQ安全中心").Type micReturn
End If
当然，这里也可以使用DeviceReplay对象来模拟按键。
