我如何将WiX属性默认设置为null? [英] How can I have a WiX Property default to null?

问题描述

我正在研究一组WiX安装程序，它们将共享一种通用形式.每个应用程序都需要设置值，但是每个应用程序都将有所不同.

I am working on a set of WiX installers that are going to share a common form. Every application needs the values set, but they are going to be different for each application.

我试图允许属性(链接到控件)具有默认值(或不具有默认值)，并允许通过命令行设置属性值.

I am trying to allow for the properties (which are linked to controls) to have a default value (or not) and to allow for the property values to be set via command line.

在我的"SharedDialog.wxs"中:

in my "SharedDialog.wxs" I have:

<Fragment>
   <PropertyRef Id="PROP1"/>
   <PropertyRef Id="PROP2"/>
   <UI>
      <Dialog Id="SharedDialog" Width="370" Height="270" Title="[ProductName]">
         <Control Type="Edit" Id="1" Property="PROP1" Wid... Indirect="no" />
         <Control Type="CheckBox" Id="2" Property="PROP2" Wid...  
           CheckBoxValue="1" Indirect="no"/>
      </Dialog>
</Fragment>

在用于特定于应用程序的项目的文件中:

In a file for the application specific project:

<Fragment>
   <Property Id="PROP1" Value="Test"/>
   <Property Id="PROP2" Value="1"/>
</Fragment>

这一切都适用于我想做的事情，但是问题是当我想这样清除值时:(因此它们没有默认值)

This all works for what I am trying to do, but the problem is that when I want to clear the values as so: (so they don't have a default)

<Fragment>
   <Property Id="PROP1"/>
   <Property Id="PROP2"/>
</Fragment>

我收到此错误:

Unresolved reference to symbol 'Property:PROP1' in section 'Fragment:'. 
Unresolved reference to symbol 'Property:PROP2' in section 'Fragment:'.

WiX还将不允许您将值设置为".问题是，据我所知，如果该属性具有值，将始终选中该复选框.如何将属性"PROP2"设置为空"?

WiX also will not let you set value to "". The problem is that as far I can tell the checkbox will always be checked if the property has a value. How can I set the property "PROP2" to "null"?

推荐答案

Nvm ...我找到了解决方法

Nvm... I found a solution

<Fragment>
   <Property Id="PROP1" Secure="yes"/>
   <Property Id="PROP2" Secure="yes"/>
</Fragment>
