WiX-将复选框值从Burn UI传递到MSI [英] WiX - passing checkbox values from Burn UI to MSI

问题描述

我在Burn中具有自定义UI，其中带有安装桌面图标复选框。而且我的MSI（也是用WiX创建）具有与替换Burn相同的功能。问题在于，Burn似乎将复选框值设置为 0 或 1 （通过 MsiProperty ），而我的MSI期望 NULL 或 NOT NULL 。如果尝试通过Burn发送复选框值，则MSI始终会将其评估为NOT NULL。我发现可以编辑我的WiX项目并进行更改：

I have custom UI in Burn with a checkbox "Install Desktop icon". And I have the same thing in my MSI (also created with WiX) that I'm replacing with Burn. The problem is that Burn seems to set checkbox values to 0 or 1 (via MsiProperty) whereas my MSI expects NULL or NOT NULL. If you try to send through the checkbox value from Burn it will always be evaluated as NOT NULL by the MSI. I have found that I can edit my WiX projects and change:

<Condition>DESKTOP_ICONS</Condition>

至：

<Condition>DESKTOP_ICONS = 1</Condition>

这将解决问题。但是，是否有任何方法可以使Burn根据复选框的值将NULL或NOT NULL传递给MSI？

and this will solve the problem. But is there any way of getting Burn to pass NULL or NOT NULL to the MSI based on the value of a checkbox?

推荐答案

Burn将 true和 checked视为 1，将 0视为false。但是，您可以在MSI中创建一个自定义操作，该操作会将数字属性转换为 NULL。看起来像这样：

Burn will treat "true" and "checked" as "1" and "0" for false. However, you could create a custom action in your MSI that would convert the numeric property into "NULL". It'd look something like:

<SetProperty Id="NULL" Value="1" After="AppSearch">DESKTOP_ICONS = 1</SetProperty>

现在属性名为 NULL（如果 DESKTOP_ICONS 属性设置为 1，则将定义一个非常有趣的名称，恕我直言。

Now the Property named "NULL" (which is a pretty funny name for a property, IMHO) will be defined if DESKTOP_ICONS property was set to "1".
