Wix，以前版本存在时的自定义对话框 [英] Wix, custom dialog when previous version exists

问题描述

我正在使用 WiX 工具集为我的应用程序进行安装.如果找到以前的版本，我想显示自定义对话框.

I'm making installation for my application with WiX toolset. I want to show custom dialog if previous version found.

现在我不知道如何检查是否有以前的版本并仅在这种情况下显示此对话框?这是我的代码.

Now I don't know how to check if there is previous version and show this dialog only in that case? Here is my code.

CustomDialogUI.wxs:

CustomDialogUI.wxs :

 <?xml version="1.0" encoding="utf-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
  <Fragment>
    <UI>
  <Dialog Id="OldVersionDlg" Width="260" Height="85" Title="[ProductName] Setup" NoMinimize="yes">
    <Control Id="No" Type="PushButton" X="132" Y="57" Width="56" Height="17"
      Default="yes" Cancel="yes" Text="No">
      <Publish Event="EndDialog" Value="Exit">1</Publish>
    </Control>
    <Control Id="Yes" Type="PushButton" X="72" Y="57" Width="56" Height="17" Text="Yes">
      <Publish Event="EndDialog" Value="Return">1</Publish>
    </Control>
    <Control Id="Text" Type="Text" X="5" Y="15" Width="250" Height="30">
      <Text>A previous version of [ProductName] is currently installed. By continuing the installation this version will be uninstalled. Do you want to continue?</Text>
    </Control>

  <Control Id="Back" Type="PushButton" X="180" Y="243" Width="56" Height="17" Text="&amp;Back">
    <Publish Event="NewDialog" Value="LicenseAgreementDlg">1</Publish>
  </Control>
  <Control Id="Next" Type="PushButton" X="236" Y="243" Width="56" Height="17" Default="yes" Text="&amp;Next">
    <Publish Event="ValidateProductID" Value="0">1</Publish>
    <Publish Event="SpawnWaitDialog" Value="WaitForCostingDlg">CostingComplete = 1</Publish>
    <Publish Event="NewDialog" Value="SetupTypeDlg">ProductID</Publish>
  </Control>
  <Control Id="Cancel" Type="PushButton" X="304" Y="243" Width="56" Height="17" Cancel="yes" Text="Cancel">
    <Publish Event="SpawnDialog" Value="CancelDlg">1</Publish>
  </Control>

  <Control Id="BannerLine" Type="Line" X="0" Y="50" Width="370" Height="0" />
  </Dialog>      
</UI>

有了这个，我创建了我想要的对话框并插入到原始的对话框链中.

With this I have created my dialog as I wanted and inserted into the original chain of dialogs.

在我的 Project.wxs 中

And in my Project.wxs

<UI Id="MyWixUI_Mondo">
      <UIRef Id="WixUI_Mondo" />
      <UIRef Id="WixUI_ErrorProgressText" />

  <DialogRef Id="OldVersionDlg" />

  <Publish Dialog="LicenseAgreementDlg" Control="Next" Event="NewDialog" Value="OldVersionDlg" Order="3">LicenseAccepted = "1"</Publish>
  <Publish Dialog="SetupTypeDlg" Control="Back" Event="NewDialog" Value="OldVersionDlg">1</Publish>
</UI>

有了这个我每次都会得到我的 OldVERsionDlg，我不知道如何让他只有在以前的版本存在时才显示.

With this I get my OldVErsionDlg everytime, and I don't know how to make him show ONLY if previous version exists.

我已经添加到 Project.wxs

I have added to Project.wxs

<Property Id="PREVIOUSVERSIONSINSTALLED" Secure="yes" />
<Upgrade Id="{80EE38CE-1A3B-445F-8CC1-31B32AA77715}">
  <UpgradeVersion Minimum="1.0.0.0" Maximum="9.0.0.0"
                  Property="PREVIOUSVERSIONSINSTALLED"
                  IncludeMinimum="yes" IncludeMaximum="no" />
</Upgrade>

并尝试过:

 <UI Id="MyWixUI_Mondo">
  <UIRef Id="WixUI_Mondo" />
  <UIRef Id="WixUI_ErrorProgressText" />

  <DialogRef Id="OldVersionDlg" />

  <Publish Dialog="LicenseAgreementDlg" Control="Next" Event="NewDialog" Value="OldVersionDlg" Order="3">LicenseAccepted = "1" AND PREVIOUSVERSIONSINSTALLED</Publish>
  <Publish Dialog="SetupTypeDlg" Control="Back" Event="NewDialog" Value="OldVersionDlg">1</Publish>
</UI>

不走运.

推荐答案

Next/Back Button Override:我不是 GUI 专家，其实这是一个被忽视的领域(对于企业部署，GUI 总是被禁止)，但我相信这样的事情可以工作 - 重新定义下一步"和后退"按钮 - 涉及 3 个对话框:

Next / Back Button Override: I am no GUI expert, in fact it is a neglected area (GUI is always suppressed for corporate deployment), but I believe something like this can work - redefining the Next and Back buttons - 3 dialogs involved:

<!-- 1. OldVersionDlg showing -->
<Publish Dialog="LicenseAgreementDlg" Control="Next" Event="NewDialog" 
         Value="OldVersionDlg">LicenseAccepted = "1" AND PREVIOUSVERSIONSINSTALLED</Publish>

<Publish Dialog="SetupTypeDlg" Control="Back" Event="NewDialog" 
         Value="OldVersionDlg">PREVIOUSVERSIONSINSTALLED</Publish>

<!-- 2. OldVersionDlg dialog not showing -->
<Publish Dialog="LicenseAgreementDlg" Control="Next" Event="NewDialog" 
         Value="SetupTypeDlg">LicenseAccepted = "1" AND NOT PREVIOUSVERSIONSINSTALLED</Publish>

<Publish Dialog="SetupTypeDlg" Control="Back" Event="NewDialog" 
         Value="LicenseAgreementDlg">NOT PREVIOUSVERSIONSINSTALLED</Publish>

实际的对话序列:

1. LicenseAgreementDlg <-> OldVersionDlg <-> SetupTypeDlg

LicenseAgreementDlg <-> SetupTypeDlg

当然，请记住在所有安装模式下进行测试:install、upgrade、repair、modify、patching、uninstall(还有一些陌生的地方，比如恢复安装——很少见).

To be sure, remember to test in all installation modes: install, upgrade, repair, modify, patching, uninstall (and there are stranger shores such as resumed installs - rarely seen).

结束:这个功能真的有必要吗?我发现像这样的功能通常会导致比好处更多的错误，但这只是个人意见.事实上，我很久以前就写过一篇关于如何在不使用设置对话框的情况下实现这种升级检查的答案.
