Wix 将项目加载到组合框中

Question

我需要使用自定义操作将项目加载到组合框中。

UI.wxs：

            <Control Id="Server" Type="ComboBox" X="30" Y="65" Width="200" Height="18" Property="DATABASE_SERVER">
                <ComboBox Property="DATABASE_SERVER">
                    <ListItem Text="[DATABASE_SERVER]" Value="[DATABASE_SERVER]" />
                </ComboBox>
                <Publish Property="LOGON_VALID" Value="0">1</Publish>
            </Control>

自定义操作

private static ActionResult EnumSqlServersIntoComboBox(Session session, IEnumerable<DataRow> rows)
{
    try
    {
        Debugger.Break();

        session.Log("EnumSQLServers: Begin");

        // Grab the combo box but make sure I'm getting only the one 
        // from WebAppInstallDlg.
        View view = session.Database.OpenView("SELECT * FROM ComboBox WHERE ComboBox.Property='DATABASE_SERVER'");
        view.Execute();

        Int32 index = 1;
        session.Log("EnumSQLServers: Enumerating SQL servers");
        foreach (DataRow row in rows)
        {
            String serverName = row["Name"].ToString();

            // Create a record for this web site. All I care about is
            // the name so use it for fields three and four.
            session.Log("EnumSQLServers: Processing SQL server: {0}", serverName);

            Record record = session.Database.CreateRecord(4);
            record.SetString(1, "DATABASE_SERVER");
            record.SetInteger(2, index);
            record.SetString(3, serverName);
            record.SetString(4, serverName);

            session.Log("EnumSQLServers: Adding record");
            view.Modify(ViewModifyMode.InsertTemporary, record);
            index++;
        }

        view.Close();

        session.Log("EnumSQLServers: End");
    }
    catch (Exception ex)
    {
        session.Log("EnumSQLServers: exception: {0}", ex.Message);
        throw;
    }

    return ActionResult.Success;
}

我想要实现的是有一个输入文本框，旁边有下拉箭头，其中包含所有加载的sql服务器。

唯一一次将 sql 服务器加载到组合框中是当我将 UI 代码更改为以下内容时：

<Control Type="ComboBox" Property="DATABASE_SERVER" Id="Server" Width="180" Height="16" X="110" Y="60" ComboList="yes" Sorted="yes" />

注意 ComboList="yes" 项目。但这对我不起作用，因为这使组合框成为一个下拉项，并且我希望能够在替代选项中“键入”。

Answer 1

我明白了：

Dialogs.wxs：

...
    <Control Id="ServerLabel" Type="Text" X="20" Y="62" Width="80" Height="25" NoPrefix="yes" Text="SQL Database:" />
    <Control Id="Server" Type="ComboBox" Height="16" Width="180" X="110" Y="60" Property="DATABASE_SERVER">
        <ComboBox Property="DATABASE_SERVER">
            <ListItem Text="[DATABASE_SERVER]" Value="[DATABASE_SERVER]" />
        </ComboBox>
        <Publish Property="LOGON_VALID" Value="0">1</Publish>
    </Control>
...

自定义操作：

[CustomAction]
public static ActionResult EnumerateSqlServers(Session session)
{
    if (null == session)
    {
        throw new ArgumentNullException("session");
    }

    session.Log("EnumerateSQLServers: Begin");

    // Check if running with admin rights and if not, log a message to
    // let them know why it's failing.
    if (false == HasAdminRights())
    {
        session.Log("EnumerateSQLServers: " + "ATTEMPTING TO RUN WITHOUT ADMIN RIGHTS");
        return ActionResult.Failure;
    }

    ActionResult result;

    DataTable dt = SmoApplication.EnumAvailableSqlServers(false);
    DataRow[] rows = dt.Select(string.Empty, "IsLocal desc, Name asc");
    result = EnumSqlServersIntoComboBox(session, rows);

    session.Log("EnumerateSQLServers: End");
    return result;
}

private static ActionResult EnumSqlServersIntoComboBox(Session session, IEnumerable<DataRow> rows)
{
    try
    {
        //Debugger.Break();

        session.Log("EnumSQLServers: Begin");

        View view = session.Database.OpenView("DELETE FROM ComboBox WHERE ComboBox.Property='DATABASE_SERVER'");
        view.Execute();

        view = session.Database.OpenView("SELECT * FROM ComboBox");
        view.Execute();

        Int32 index = 1;
        session.Log("EnumSQLServers: Enumerating SQL servers");
        foreach (DataRow row in rows)
        {
            String serverName = row["Name"].ToString();

            // Create a record for this web site. All I care about is
            // the name so use it for fields three and four.
            session.Log("EnumSQLServers: Processing SQL server: {0}", serverName);

            Record record = session.Database.CreateRecord(4);
            record.SetString(1, "DATABASE_SERVER");
            record.SetInteger(2, index);
            record.SetString(3, serverName);
            record.SetString(4, serverName);

            session.Log("EnumSQLServers: Adding record");
            view.Modify(ViewModifyMode.InsertTemporary, record);
            index++;
        }

        view.Close();

        session.Log("EnumSQLServers: End");
    }
    catch (Exception ex)
    {
        session.Log("EnumSQLServers: exception: {0}", ex.Message);
        throw;
    }

    return ActionResult.Success;
}
