I'm building a .NET application for Power BI embedded.Im getting the following error.
I've used the Power BI api to print the pages in the report using event handlers and user defined functions.I'm getting the Pages array as o/p using event handlers but not using user defined functions(promise state as pending)
Ive tried using event handlers and using function.
Im getting o/p for event handlers but not using function.
Before using the APIs, we must Wait for the component / report to get loaded. In the line 20, You are waiting for report to get rendered and then using the API and you can see the pages in the code and it's not the case with code in line 7 Where you are using API when the report is not even available

I am struggling to figure out what how I can resolve an issue I am seeing with this data flow job. I saw a similar thread on the apache beam archives question thread but I did not quite understand how to use this information.
Essentially data is being streamed into Big Query (which works), I am trying to write these BQ rows into spanner in the same dataflow job which raises the following runtime exception:
java.lang.IllegalArgumentException: Attempted to get side input window for GlobalWindow from non-global WindowFn
org.apache.beam.sdk.transforms.windowing.PartitioningWindowFn$1.getSideInputWindow(PartitioningWindowFn.java:47) ....
The relevant section of the data flow graph can be seen here data flow graph and the code I am using to write to spanner is here:
sensorReports
.apply("WindowSensorReportByMonth",
Window.<TableRow>into(FixedWindows.of(Duration.standardMinutes(5))).withAllowedLateness(Duration.ZERO).discardingFiredPanes()
.triggering(AfterProcessingTime.pastFirstElementInPane()
.plusDelayOf(Duration.standardMinutes(1)))
.discardingFiredPanes())
.apply("CreateSensorReportMutation", ParDo.of(new RowToMutationTransform()))
.apply("Write to Spanner",
SpannerIO.write()
.withDatabaseId(propertiesUtils.getSpannerDBId())
.withInstanceId(propertiesUtils.getSpannerInstanceId())
.withProjectId(propertiesUtils.getSpannerProjectId())
.withBatchSizeBytes(0));
SpannerIO.write() internally reads the DB schema using a global window and uses this as a side input, so your non-global-windowed Mutations are clashing with it.
You could put all your Mutations into a global window before passing to Spanner.IO.write()
.apply("To Global Window", Window.into(new GlobalWindows()))
but in BEAM versions 2.5-2.8, this will result in either an error or nothing ever being written (as SpannerIO never supported streaming pipelines).
Edited answer:
However, BEAM before version 2.9.0 does not support streaming pipelines. V2.4 and earlier did, provided you don't pass a windowed PCollection to it.
You will be pleased to hear that all is fixed in version 2.9 (release in progress) where the SpannerIO both supports streaming writes and handles the windowing correctly.
I was not able to understand how to log to a custom event log using c++.
I will explain better: googling around for hours I discovered that the most recent way to use windows log should be that named "Windows Event Log" built on top of ETW (here https://msdn.microsoft.com/en-us/library/windows/desktop/aa385780%28v=vs.85%29.aspx)
I want that my log events shows in EventViewer under "Application and services logs"\"MyAppCustomLog"
So I did these steps
- Edited registry creating the MyAppCustomLog entry (HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\EventLog\MyAppCustomLog)
created an Instrumentation Manifest (xml file) using the SDK utility "ecmangen", creating the manifest file MyAppLog.man
built the .rc and .bin and .h files using message compiler: mc -um MyAppLog.man -h . -z MyAppLog
registered the manifest using the wevtutil this way: wevtutil im MyAppLog.man
create a simple consolle application that calls the in MyAppLog.h (the header created by message compiler) in this way:
...
ULONG result = EventRegisterMyAppLog();
...
EventWriteMyAppLogSimpleEvent();
...
EventUnregisterMyAppLog();
...
But if I execute those methods where does the event go? How can I associate it to my custom event log? I could not figure it out...
Am I doing the wrong thing?
I am sure that some pieces are missing from my puzzle but which ones?
My question is: how to link the event I defined in manifest (MyAppLogSimpleEvent) to the custom event log MyAppCustomLog that I see in event viewer?
Could someone explain me how to set a relation between my events and the custom log?
In case this is the wrong way to do this (write events defined in some kind of manifest in a custom event log) could you please explain me what do I have to do?
Thank you very much for any help
I want to make a log with errors during the execution of my app. I'm trying to write an event to the windows Event Viewer with a VCL form application with C++ Builder XE5.
I'm using Vcl.SvcMgr.TEventLogger class.
The code in the header file is :
TEventLogger *Event;
The code in the cpp file is :
Event=new TEventLogger("MySource");
Event->LogMessage("MyMessage");
But beside my message, in the error description in the Event Viewer there is a message : "The description for Event ID 0 from source MySource cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted." . How can I remove that description and write only the message that I want? Should I be using other C++ class? I couldn't find any documentation about this class. The idea of using Event Viewer is that when the application is running on an user with restricted rights he won't be able to write to files, meaning I can't just type into a ".txt" file. If anyone else has a different idea how to make a log with errors, please share! :)
Thanks in advance,
Zdravko
This message normally shows up if there is no message files set up within your application. In contrast to Unix syslog and similar logging packages, the Windows event log normally combines messages from the message file and the text you want to log and if there is no message file set up and registered, the event view complains about it.
I'd like to enable my app to make warnings and errors visible to the global "Application" log in Windows Event Viewer. I've successfully followed the directions here that helped me get ETW up and running, but I only see events when I explicitly enable logging via a tracing program, and even then they only show up in the generated .etl file, not in the global log.
How can I programmatically register and write events to the global Application log, so that when users run event viewer, they'll see events from my app? Is it even possible? In a nutshell, I want to end up with something like the screenshot below, just with less photoshopping required:
ETW seems to be quite complex for your purpose, here's the procedure to write to the Event Log:
a) One-time (you would typically do this while installing your application) Register your application as a Event Provider; only the EventMessageFile entry is really required:
- key = HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\eventlog\Application\MyCoolGame
- string name (REG_EXPAND_SZ) = EventMessageFile
- string value = C:\Windows\Microsoft.NET\Framework\v4.0.30319\EventLogMessages.dll
b) On program startup: Register Event Source and receive a handle:
hEventLog = RegisterEventSource(NULL, lpszAppNameName);
c) Use the ReportEvent function to write entries to the Event Log:
TCHAR szLogBuffer[] = _T("Started new multiplayer server.");
const TCHAR *lpszEventStrings[2] = {szLogBuffer, NULL};
ReportEvent(hEventLog, EVENTLOG_INFORMATION_TYPE, 0, 1, NULL, 1, 0, lpszEventStrings, NULL)
d) On program shutdown:
DeregisterEventSource(hEventLog);
The Windows Event Tracing API was intended to supersede the older Windows Event Logging API for logging events to the Event Log, starting with Windows Vista. But to this day it is difficult to find clear examples online showing how to use this newer Event Tracing for Windows (ETW) API.
It is fundamental for applications - and especially services - to log events to the Windows Event Log under System or Application. But Microsoft does not provide any clear documentation for this very common use case. Instead, the current online documentation for Event Tracing drags you through the entire complexity of ETW.
That said, Microsoft offers a sample solution for native VC++ which works well. The solution and project (from VS2008!) loaded fine into Visual Studio 2022.
The included XML manifest in this sample defines 5 events, but only the first, fourth and fifth are associated with the "channel" for the Windows Application Event Log. The second and third events are associated with an "analytic channel" for ETW and will not appear in Application or System logs within Event Viewer (such ETW events are typically captured/monitored through other means). So the sample demonstrates how to log to the Event Log or to ETW using the newer API. The readme.txt file in this solution is instructive.
Also helpful is an archived Microsoft forum posting called FAQ: Common Questions for ETW and Windows Event Log. It describes the various ETW channels, defines what WPP means and provides a number of other details.
There is a third Windows API for ETW logging called TraceLogging which builds upon and simplifies the ETW API; however, for logging to the traditional Application and System Event Logs shown in Event Viewer, you must stay with either manifest-based ETW logging or the older Windows XP/Server 2003 Event Logging API.
I am using blazeDS in my web application. I am facing issue with Java and flex.
I have used function to load service in creation complete event of application. And I need to get value in combo box and do some manipulation. But my function which will trace the value, is being called before service is loading. for that reason function is not returning any value.
you can overcome by doing following changes
1) call webservice in Application initizlize event
2) Call your method in ResultEvent triggers on result of Webservice
or
3) IF Still you face same issue you can call it using callLater()
or
4)IF callLater() wont work to, then you can use Event collectionchange of ListCollectionView a Parent Class of ArrayCollection, XMLListCollection
I personaly recommend DO Steps 1 and 4 Only.
Hopes that helps
