我正在使用HeatDirectory来创建源.wxs文件.在拾取目录中有一个exe应该作为服务安装.实际上,如果我自己创建组件,我知道如何安装服务,但我不知道如何在自动生成的组件中包含ServiceInstall.有什么建议吗？

        <HeatDirectory DirectoryRefId="Guardian" OutputFile="Source\GuardianSource.wxs" Transforms="Filter.xsl" Directory="..\Setup\C24.Guardian\bin\Debug" PreprocessorVariable="var.GuardianPath" ComponentGroupName="GuardianGroup" ToolPath="$(WixToolPath)" SuppressCom="true" SuppressFragments="true" SuppressRegistry="true" SuppressRootDirectory="true" AutoGenerateGuids="true" GenerateGuidsNow="false">
    </HeatDirectory>

有没有办法跳过链中的一个包？我看过“InstallCondition”并且有这样的代码。

                      <ExePackage Id="RoboMongo"
                        DisplayName="RoboMongo"
                        Cache="no"
                        Compressed="no"
                        PerMachine="yes"
                        Permanent="no"
                        Vital="no"
                        Name="redist\Robomongo-0.8.4-RC2-i386.exe"
                        DownloadUrl="$(var.RoboMongoUrl)"
                        InstallCondition="ComponentSelect_5"
                        InstallCommand='/Action=Install'
                        UninstallCommand="/Action=Uninstall"
                        RepairCommand ="/Action=Repair"
                        DetectCondition="RoboMongoInstalled">

            <RemotePayload Description="????????? ????????????????? MongoDB"
            Version ="0.8.4.2"
                ProductName="RoboMongo"
                Hash="71C17E48BC32304FA8724FFA7CA1C4C08891BC97" Size="7141182" />

但我不想在 InstallCondition=false 上卸载它。我只想跳过它。

先感谢您。

我正在使用Microsoft SQL Server.

IF EXISTS (
    SELECT *
    FROM INFORMATION_SCHEMA.COLUMNS
    WHERE TABLE_NAME = 'ServerSettings'
        AND COLUMN_NAME = 'MapIsAlwayCalcLenByWebServices'
)
    IF (
        SELECT MapIsAlwayCalcLenByWebServices
        FROM ServerSettings
    ) = 0
        UPDATE ServerSettings
        SET MapCalculateDistanceSource = 0

有没有人知道为什么这段代码会抛出错误"无效的列名".我认为第二次选择仅在第一次if为真时才执行.
