我正在尝试创建一个对话框以在安装程序检查 SQL 服务器是否存在时显示。我使用了以下代码:

<Control Id="Next" Type="PushButton" X="244" Y="243" Width="56" Height="17" Text="!(loc.WixUINext)">

    <!--Show Waiting dialog-->
    <Publish Property="SQLServerChecked" Value="0">1</Publish>
    <Publish Event="SpawnWaitDialog" Value="WaitCheckSQLServerDlg">
        SQLServerChecked = "1"
     </Publish>

   <!--Checks the SQL server exists-->
   <Publish Event="DoAction" Value="CheckSQLServerExists">1</Publish>

   <Publish Property="SQLServerChecked" Value="1">1</Publish>

</Control>

但是我的 WaitCheckSQLServerDlg 显示,永远不会消失,并且 Action CheckSQLServerExists 没有运行。我将如何更改我的代码,以便在 CheckSQLServerExists 操作运行时显示 WaitCheckSQLServerDlg?

谢谢
