維克斯自定義對話框錯誤2856

Question

我已經添加到安裝WiX的安裝使用自定義對話框：ProgramDataInstallDlg

這就是我的UI標籤的樣子對整個項目：

<UI Id="my_UI"> 
    <UIRef Id="WixUI_FeatureTree" /> 
    <DialogRef Id="ProgramDataInstallDlg" /> 

    <Publish Dialog="CustomizeDlg" Control="Next" Event="NewDialog" Value="ProgramDataInstallDlg">1</Publish> 
    <Publish Dialog="VerifyReadyDlg" Control="Back" Event="NewDialog" Value="ProgramDataInstallDlg">1</Publish> 
</UI> 

如果只按下下一項，一切正常。但是如果在VerifyReadyDlg中按下後退按鈕或按下CustomizeDlg中的下一個按鈕。我得到錯誤2856

這是安裝日誌說：

DEBUG: Error 2856: Creating a second copy of the dialog ProgramDataInstallDlg 
The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2856. The arguments are: ProgramDataInstallDlg, ,

的哪些錯誤？

如果您自定義UI，我建議創建一個自定義WixUI_FeatureTree。

看看下面的代碼。我採用了默認模板，並在適當的地方使用了對話框名稱。

從您的自定義對話框中刪除以下行：

<Publish Event="SpawnDialog" Value="VerifyReadyDlg">1</Publish> 
<Publish Event="SpawnDialog" Value="CustomizeDlg">1</Publish> 

主對話框
