我使用CAQuietExec的自定义操作在某些情况下失败 - 日志文件中出现的唯一错误消息对我来说非常适合作为开发人员,对最终用户来说是无用的。我的目标是在回滚安装之前捕获失败的操作并预设标准错误消息。
为此,基于我的研究,我决定自己需要编写自己的自定义动作dll,因此我开始关注this tutorial。在这个阶段,我的dll只记录测试消息并尝试将错误消息传回对话框屏幕。但是当我编译并运行msi时,根本没有任何事情发生 - 没有任何记录,也没有任何错误消息。看看Orca中的msi,它看起来还不错 - 但正如你在下面看到的那样,测试dll应该导致安装在实际运行时立即中止而不是。
所以我的问题是:我是否会以最佳方式向用户提供反馈?如果是这样,任何想法为什么我的自定义操作都没有运行?

呃,我浪费了几个小时的时间:但对于遇到同样问题的人,我会用自定义动作发布我的问题的答案 - 希望这会节省你的时间和挫折感。
我把测试操作很早地放在序列中,以为我会看到错误消息对话框。因此,我并没有真正尝试完成安装 - 当欢迎对话框出现时,我认为我的行动没有运行。但是,它必须已运行,因为当您实际选择某个功能并允许安装进度时,将显示错误消息。
尽管如此,如果有人能够提供一些见解,以确定这是否是提供一些用户对CAQuietExec正常运行的用户反馈的最佳方式,那么我们将不胜感激。

您对此解决方案有何看法:
Record record = new Record();
record.FormatString = string.Format("Something has gone wrong!");
session.Message(
InstallMessage.Error | (InstallMessage) ( MessageBoxIcon.Error ) |
(InstallMessage) MessageBoxButtons.OK,
record );
另一种方法 - 创建自己的UI并根据需要显示任何消息。 小例子:
自定义操作:
[CustomAction]
public static ActionResult CheckSqlSessionState(Session session)
{
try
{
session.SendMessage(InstallMessage.Info, "Check Sql Session State");
return ActionResult.Success;
}
catch (Exception exception)
{
session.SendMessage(InstallMessage.Error,
string.Format("Error during the cheking sesssion state. {0}", exception.Message));
return ActionResult.Failure;
}
}
注册:
<CustomAction Id="WiXSetup.CustomAction.CheckSqlSessionState"
BinaryKey="WiXSetup.CustomActions.dll"
DllEntry="CheckSqlSessionState" Execute="deferred" />
<CustomAction Id="SetCheckSqlSessionStateDataValue"
Return="check"
Property="WiXSetup.CustomAction.CheckSqlSessionState" />
<InstallExecuteSequence>
<Custom Action="SetCheckSqlSessionStateDataValue" Before="WiXSetup.CustomAction.CheckSqlSessionState">NOT Installed</Custom>
<Custom Action="WiXSetup.CustomAction.CheckSqlSessionState" After="WiXSetup.CustomAction.UpdateHomePageUrls">NOT Installed</Custom>
</InstallExecuteSequence>
CSharp UI:
using Microsoft.Deployment.WindowsInstaller;
private ExternalUIRecordHandler recordHandler;
// ...
IntPtr parent = IntPtr.Zero;
recordHandler = RecordHandler;
private MessageResult RecordHandler(InstallMessage messageType, Record messageRecord, MessageButtons buttons, MessageIcon icon, MessageDefaultButton defaultButton)
{
switch (messageType)
{
case InstallMessage.Info:
log.Info(message);
return MessageResult.OK;
case InstallMessage.Initialize:
log.Debug(message);
return MessageResult.OK;
case InstallMessage.ActionData:
log.Debug(message);
return MessageResult.OK;
case InstallMessage.ActionStart:
log.Debug(message);
return MessageResult.OK;
case InstallMessage.CommonData:
return MessageResult.OK;
case InstallMessage.Error:
log.Error(message);
return MessageResult.OK;
case InstallMessage.FatalExit:
log.Fatal(message);
return MessageResult.OK;
case InstallMessage.FilesInUse:
return MessageResult.No;
case InstallMessage.OutOfDiskSpace:
break;
case InstallMessage.Progress:
return MessageResult.OK;
case InstallMessage.ResolveSource:
return MessageResult.No;
case InstallMessage.ShowDialog:
return MessageResult.OK;
case InstallMessage.Terminate:
return MessageResult.OK;
case InstallMessage.User:
return MessageResult.OK;
case InstallMessage.Warning:
log.Warn(message);
return MessageResult.OK;
}
return MessageResult.No;
}
