验证WIX安装程序中的输入控件

Question

我是WIX的新手。我想验证像Textbox这样的输入控件是否为null，以及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。如果我发送的参数如何返回值与保持在同一安装页面。

<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任何其他验证方式。

提前感谢

这是一个正在工作的自定义Wix对话框

这段代码创建了一个带有自定义操作的自定义UI对话框。这个对话框的目的是当我们安装桌面应用程序时，我们可以设置Db连接信息。
