在 WiX 中的对话框之间插入自定义操作 (InstallUISequence) [英] Inserting Custom Action between Dialogs (InstallUISequence) in WiX

问题描述

我有两个自定义对话框(加上必需的 ExitDlg、FatalErrorDlg 等)，第一个使用 Edit 控件设置属性，第二个使用 Text 控件显示此属性.这是有意义的代码:

I have two custom dialog boxes (plus the required ones ExitDlg, FatalErrorDlg, etc.), the first one sets a property using an Edit control and the second one shows this property using a Text control. Here is the meaningful code:

<Dialog Id="DialogA" ...>
  <Control Id="ControlEdit" Type="Edit" Property="MY_PROPERTY" .../>
  <Control Id="ControlNext" Type="PushButton" ...>
    <Publish Event="EndDialog" Value="Return" /></Control>
</Dialog>

然后是第二个对话框:

<Dialog Id="DialogB" ...>
  <Control Id="ControlText" Type="Text" Text="[MY_PROPERTY]" .../>
  <Control Id="ControlBack" Type="PushButton" ...>
    <Publish Event="EndDialog" Value="Return" /></Control>
  <Control Id="ControlNext" Type="PushButton" ...>
    <Publish Event="EndDialog" Value="Return" /></Control>
</Dialog>

以及动作顺序:

<InstallUISequence>
   <Show Dialog="DialogA" Before="MyCustomAction" />
   <Custom Action="MyCustomAction" Before="DialogB" />
   <Show Dialog="DialogB" Before="ExecuteAction" />
</InstallUISequence>

自定义操作会更改 MY_PROPERTY 的值.我的问题是如何使 DialogB 中的后退按钮返回到 DialogA.使用 NewDialog 很简单，但是我无法在对话框之间执行自定义操作，或者我可以吗?

The custom action changes the value of MY_PROPERTY. My problem is how to make the Back button in DialogBget back to DialogA. Using NewDialog is simple, but then I can't get the custom action to be executed between the dialogs, or can I?

在@caveman_dick 的回答之后，我几乎像他说的那样尝试更改DialogA，但我没有使用EndDialog，而是更改为Action="新对话框"Value="DialogB".但是现在没有调用自定义操作.如果我删除 Publish 事件以转到下一个对话框，则调用 CA.如果我按照@caveman_dick 所说的那样离开，我将无法从 DialogB 回到 DialogA.

After the answer from @caveman_dick, I tried to change the DialogA almost like he said, but instead of using EndDialog, I changed to Action="NewDialog" Value="DialogB". But now the Custom Action isn't being called. If I remove the Publish event to go to next dialog, then the CA is called. If I leave as @caveman_dick said, I can't get back to DialogA from DialogB.

在WiX 3.6:Windows Installer XML 开发人员指南一书中搜索后，我发现了以下内容:如果您有多个 Publish 事件，它们必须有条件语句作为其内部文本.否则，所有事件都不会发布."

After searching in book WiX 3.6: A Developer's Guide to Windows Installer XML, I found the following: "if you have more than one Publish event, they must have conditional statements as their inner text. Otherwise, all of the events simply won't be published."

所以@caveman_dick 的答案是正确的，只是你需要更改为以下内容:

So the answer from @caveman_dick is correct, except that you need to change to the following:

<Publish ...>1</Publish>

推荐答案

而不是在 InstallUISequence 中安排自定义操作，您可以在按钮单击时发布它:

Rather than scheduling the custom action in the InstallUISequence you can publish it on the button click:

<Dialog Id="DialogA" ...>
   <Control Id="ControlEdit" Type="Edit" Property="MY_PROPERTY" .../>
   <Control Id="ControlNext" Type="PushButton" ...>
       <Publish Event="DoAction" Value="MyCustomAction">1</Publish>
       <Publish Event="EndDialog" Value="Return">1</Publish>
   </Control>
</Dialog>

Publish 元素的条件需要显式评估为 true 才能运行，因此添加 "1" 作为 Publish 的文本元素.

The Publish element's condition needs to explicitly evaluate to true to run, so add "1" as the text of the Publish elements.
