等价于:

<Control Id="DlgTitle" Type="Text" X="10" Y="5" Width="292" Height="25" Transparent="yes">

<Text>{\MSSansBold10}自定义安装</Text>

<Condition Action="hide">ProgressType0 &lt;&gt; "Install"</Condition>

</Control>

<Control Id="DlgTitle2" Type="Text" X="10" Y="5" Width="292" Height="25" Transparent="yes">

<Text>{\MSSansBold10}修改安装</Text>

<Condition Action="hide">ProgressType0 &lt;&gt; "Modify"</Condition>

</Control>
