Question

我正在使用WiX工具集安装我的应用程序。如果找到以前的版本，我想显示自定义对话框。

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。

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，我按照自己的意愿创建了对话框并将其插入到原始的对话链中。

在我的Project.wxs

中

<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，如果以前的版本存在，我不知道如何让他显示。

我已添加到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：

 <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>

没有运气。

下一步/后退按钮替代 ：我不是GUI专家，实际上这是一个被忽略的领域（对于公司部署，GUI始终被抑制），但是我相信这样可以起作用-重新定义“下一步”和“后退”按钮-涉及3个对话框：

<!-- 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>

实际对话框序列 ：

LicenseAgreementDlg <-> OldVersionDlg <-> SetupTypeDlg
LicenseAgreementDlg <-> SetupTypeDlg

请确保记得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，例如恢复安装-很少见。）

结束语 ：此功能真的必要吗？我发现类似这样的功能通常会导致更多的错误而不是好处，但这只是个人观点。实际上，我很久以前就如何实现这样的an upgrade check without using setup dialogs写了一个答案。
