验证 WIX 安装程序中的输入控件

【中文标题】验证 WIX 安装程序中的输入控件

【英文标题】：To validate the input controls in WIX Installer

【发布时间】：2020-08-21 07:30:00

【问题描述】：

我是 WIX 的新手。我想验证文本框等输入控件不为空，密码和确认密码是否相同。 我尝试在自定义操作中执行此操作，但无法发送参数。 如果我发送参数如何返回值以留在同一安装页面中。

<Dialog Id="XXX" Width="370" Height="270" Title="Installation">
<Control Id="Next" Type="PushButton" X="236" Y="243" Width="56" Height="17" Default="yes" Text="!(loc.WixUINext)" >
<Publish Event="DoAction" Value="CheckingPID">1</Publish>
<Publish Event="SpawnDialog" Value="InvalidPidDlg">PIDACCEPTED = "0"</Publish>
<Control Id="Usernamelbl" Type="Text" X="20" Y="100" Width="95" Height="10" NoPrefix="yes" Property="WIXUI_INSTALLDIR" Text="Username:" />
<Control Id="UsernameVal" Type="Edit" X="125" Y="100" Width="200" Height="17" Property="SETUSERNAME"  Indirect="no" Disabled="no" />

</Dialog>

<CustomAction Id="CheckingPID"  BinaryKey="CustomActionBinary"   Impersonate="no"  DllEntry="Validate"  Execute="immediate" Return="check"/>

  [CustomAction]
        public static ActionResult Validate(Session session)
        
        MessageBox.Show(Session.CustomActionData["SETUSERNAME"]);
        
            return ActionResult.Success;
        

这是正确的验证方式还是其他任何验证方式。

提前致谢

这是一个有效的自定义 Wix 对话框

此代码使用自定义操作创建自定义 UI 对话框。此对话框的目的是在我们安装桌面应用程序时，我们可以设置 Db 连接信息。

【讨论】：

其实可以的。我可以进行所有验证，但问题是我无法转到下一页。当自定义操作调用时，只有 ActionResult.Failure 有效，我尝试了其他返回枚举，它也没有帮助我.. 建议我验证成功后如何前往下一页。

我添加了更多基于同一个安装程序的代码。请在此处查看。 ***.com/questions/59685153/…
