如果

今天想要用 WixToolset 去做自訂的頁面了話 (ex:我們要設定系統要修改HelloWorld內的 appsettings.json 某段連接

接下來會談到3個部分

1.畫面部分
2.自訂動作
3.自訂動作介接畫面
這會花幾天來介紹

首先來講畫面部分，昨天的頁面使用WixUI_InstallDir，
我們現在要對目前的安裝包增加系統設定值的頁面，
所以我們要拆解並知道WixUI_InstallDir裡面的構造，
才能加入其他的頁面。

我們從官方的Github內
https://github.com/wixtoolset/wix3/blob/develop/src/ext/UIExtension/wixlib
尋找WixUI_InstallDir.wxs

 <UI Id="WixUI_InstallDir">
    <TextStyle Id="WixUI_Font_Normal" FaceName="Tahoma" Size="8" />
    <TextStyle Id="WixUI_Font_Bigger" FaceName="Tahoma" Size="12" />
    <TextStyle Id="WixUI_Font_Title" FaceName="Tahoma" Size="9" Bold="yes" />

    <Property Id="DefaultUIFont" Value="WixUI_Font_Normal" />
    <Property Id="WixUI_Mode" Value="InstallDir" />

    <DialogRef Id="BrowseDlg" />
    <DialogRef Id="DiskCostDlg" />
    <DialogRef Id="ErrorDlg" />
    <DialogRef Id="FatalError" />
    <DialogRef Id="FilesInUse" />
    <DialogRef Id="MsiRMFilesInUse" />
    <DialogRef Id="PrepareDlg" />
    <DialogRef Id="ProgressDlg" />
    <DialogRef Id="ResumeDlg" />
    <DialogRef Id="UserExit" />
            
    <Publish Dialog="BrowseDlg" Control="OK" Event="DoAction" Value="WixUIValidatePath" Order="3">1</Publish>
    <Publish Dialog="BrowseDlg" Control="OK" Event="SpawnDialog" Value="InvalidDirDlg" Order="4"><![CDATA[NOT WIXUI_DONTVALIDATEPATH AND WIXUI_INSTALLDIR_VALID<>"1"]]></Publish>

    <Publish Dialog="ExitDialog" Control="Finish" Event="EndDialog" Value="Return" Order="999">1</Publish>

    <Publish Dialog="WelcomeDlg" Control="Next" Event="NewDialog" Value="LicenseAgreementDlg">NOT Installed</Publish>
    <Publish Dialog="WelcomeDlg" Control="Next" Event="NewDialog" Value="VerifyReadyDlg">Installed AND PATCH</Publish>

    <Publish Dialog="LicenseAgreementDlg" Control="Back" Event="NewDialog" Value="WelcomeDlg">1</Publish>
    <Publish Dialog="LicenseAgreementDlg" Control="Next" Event="NewDialog" Value="InstallDirDlg">LicenseAccepted = "1"</Publish>

    <Publish Dialog="InstallDirDlg" Control="Back" Event="NewDialog" Value="LicenseAgreementDlg">1</Publish>
    <Publish Dialog="InstallDirDlg" Control="Next" Event="SetTargetPath" Value="[WIXUI_INSTALLDIR]" Order="1">1</Publish>
    <Publish Dialog="InstallDirDlg" Control="Next" Event="DoAction" Value="WixUIValidatePath" Order="2">NOT WIXUI_DONTVALIDATEPATH</Publish>
    <Publish Dialog="InstallDirDlg" Control="Next" Event="SpawnDialog" Value="InvalidDirDlg" Order="3"><![CDATA[NOT WIXUI_DONTVALIDATEPATH AND WIXUI_INSTALLDIR_VALID<>"1"]]></Publish>
    <Publish Dialog="InstallDirDlg" Control="Next" Event="NewDialog" Value="VerifyReadyDlg" Order="4">WIXUI_DONTVALIDATEPATH OR WIXUI_INSTALLDIR_VALID="1"</Publish>
    <Publish Dialog="InstallDirDlg" Control="ChangeFolder" Property="_BrowseProperty" Value="[WIXUI_INSTALLDIR]" Order="1">1</Publish>
    <Publish Dialog="InstallDirDlg" Control="ChangeFolder" Event="SpawnDialog" Value="BrowseDlg" Order="2">1</Publish>
            
    <Publish Dialog="VerifyReadyDlg" Control="Back" Event="NewDialog" Value="InstallDirDlg" Order="1">NOT Installed</Publish>
    <Publish Dialog="VerifyReadyDlg" Control="Back" Event="NewDialog" Value="MaintenanceTypeDlg" Order="2">Installed AND NOT PATCH</Publish>
    <Publish Dialog="VerifyReadyDlg" Control="Back" Event="NewDialog" Value="WelcomeDlg" Order="2">Installed AND PATCH</Publish>

    <Publish Dialog="MaintenanceWelcomeDlg" Control="Next" Event="NewDialog" Value="MaintenanceTypeDlg">1</Publish>

    <Publish Dialog="MaintenanceTypeDlg" Control="RepairButton" Event="NewDialog" Value="VerifyReadyDlg">1</Publish>
    <Publish Dialog="MaintenanceTypeDlg" Control="RemoveButton" Event="NewDialog" Value="VerifyReadyDlg">1</Publish>
    <Publish Dialog="MaintenanceTypeDlg" Control="Back" Event="NewDialog" Value="MaintenanceWelcomeDlg">1</Publish>

    <Property Id="ARPNOMODIFY" Value="1" />
</UI>

<UIRef Id="WixUI_Common" />

我們將這段程式碼替換到我們昨天的安裝包上的
這段程式碼就好 ↓↓↓

<UI> <UIRef Id="WixUI_InstallDir" /></UI>

而WIXUI_INSTALLDIR參數指定的部分還需要保留 ↓↓↓ 別刪掉了！否則會出錯給你看

<Property Id="WIXUI_INSTALLDIR" Value="INSTALLFOLDER" />

建置後，可以發現跟昨天安裝包安裝順序是一樣的！！！

再來我們了解一下這框架。

1. 頁面註冊部分
   這個是目前 WIXUI_INSTALLDIR有使用到的頁面。
2. 頁面順序
   除了BrowseDlg 瀏覽框 ExitDialog離開框以外
   我們可以看到基本順序WelcomeDlg > LicenseAgreementDlg > InstallDirDlg> VerifyReadyDlg
   對應上我們 Day5的看的安裝包頁面順序是一樣的
   
   
   
   

而關鍵字 Control="Back":上一頁， Control="Next":下一頁
使用Value去銜接上下頁的頁面名稱。

order 了話則是執行的順序，你可以看到預設InstallDirDlg的next下了很多動作

<Publish Dialog="InstallDirDlg" Control="Next" Event="SetTargetPath" Value="[WIXUI_INSTALLDIR]" Order="1">1</Publish>
<Publish Dialog="InstallDirDlg" Control="Next" Event="DoAction" Value="WixUIValidatePath" Order="2">NOT WIXUI_DONTVALIDATEPATH</Publish>
<Publish Dialog="InstallDirDlg" Control="Next" Event="SpawnDialog" Value="InvalidDirDlg" Order="3"><![CDATA[NOT WIXUI_DONTVALIDATEPATH AND WIXUI_INSTALLDIR_VALID<>"1"]]></Publish>
<Publish Dialog="InstallDirDlg" Control="Next" Event="NewDialog" Value="VerifyReadyDlg" Order="4">WIXUI_DONTVALIDATEPATH OR WIXUI_INSTALLDIR_VALID="1"</Publish>

內容如果是1的，就是一定會顯示的意思，
至於LicenseAccepted = "1" 或
CDATA[NOT WIXUI_DONTVALIDATEPATH AND WIXUI_INSTALLDIR_VALID<>"1"
這些已經寫好的語法...我個人是這麼認為的

要就要google了，
哈哈，我們先跳過不看他!!!

還想了解詳細的元件介紹需要看官方介紹，
https://wixtoolset.org/documentation/manual/v3/xsd/wix/publish.html
或者參考 stoneniqiu
https://www.cnblogs.com/stoneniqiu/p/3363873.html

• 後記

我參考的文章是很久前寫的，
WixToolset 後來將原始碼都轉到github上面，
今年看時文章內的前往網頁就錯了，
為了找原始碼路徑，也花了一陣子查...

有了 UI原始碼後，
明天我們就能新增其他自訂的頁面，
然後加入了!!!
