ProgressText不适用于WiX中的自定义操作

Question

我想在安装过程中显示自定义操作的进度文本.我在WiX Progress Text中为自定义操作实现了代码,但它不起作用.

显示所有其他文本(例如文件副本),正确填充ActionText表,并且ActionText.Action与CustomAction.Actuib值匹配.有谁知道出了什么问题？这是代码:

主要WiX项目:

<Product>
  <CustomAction Id="MyCA" BinaryKey="MyCALib"
                DllEntry="MyCAMethod" Execute="deferred"
                Return="check" />
  <InstallExecuteSequence>
     <Custom Action="MyCA" Before="InstallFinalize" />
  </InstallExecuteSequence>
  <UI>
    <UIRef Id="MyUILibraryUI" />
  </UI>
</Product>

UI库:

<Wix ...><Fragment>

  <UI Id="MyUILibraryUI">

    <ProgressText Action="MyCA">Executing my funny CA...
    </ProgressText>

    ...

    <Dialog Id="Dialog_Progress" ...>
      <Control Id="Ctrl_ActionText"
               Type="Text" ...>
        <Subscribe Event="ActionData" Attribute="Text" />
      </Control>

  ...

C#自定义动作库:

public class MyCALib
{
  [CustomAction]
  public static ActionResult MyCAMethod(Session session)
  {
      System.Threading.Thread.Sleep(10000); // to show text
      // do something
      System.Threading.Thread.Sleep(10000); // to show text

      return ActionResult.Success;
  }
}

The problem is that you are using "ActionData" but you are not sending a message to the UI with this action data from your custom action.

You must add something like:

public class MyCALib
{
  [CustomAction]
  public static ActionResult MyCAMethod(Session session)
  {
      using (Record record = new Record(0))
      {
          record.SetString(0, "Starting MyCAMethod");
          Session.Message(InstallMessage.ActionData, record);
      }

      System.Threading.Thread.Sleep(10000); // to show text
      // do something
      System.Threading.Thread.Sleep(10000); // to show text

      return ActionResult.Success;
  }
}

You can send as many messages as you want from your CA.

If you were using "ActionText" instead it will work but will display the custom action name without additional/custom information.
