I am using Delphi XE2 and Chromium CEF4Delphi. I am trying to use a web page via the TChromiumWindow component and would like to detect when an element is selected / clicked.
I saw this post..
Delphi Chromium - launch a command in Delphi application when button in web page is clicked by user
Unfortunately, I cant find the function AddEventListenerProc in the CEF4Delphi library. Neither can I find an alternative way to monitor a button / element click.
I would like to use the TChromiumWindow component to act as a "fron-end" to my app and would like to monitor user button clicks etc.
Can anyone help please ? I did try the developer forum but I dont see much activity there and was unable to register.
Many thanks..
The DCEF3 project has a group here : https://groups.google.com/forum/#!forum/delphichromiumembedded
But the CEF4Delphi and OldCEF4Delphi projects have a developers forum here :

That forum has new posts almost every day and I try to answer them as soon as I can, usually in less than 24 hours.

The link you posted is very old and many things have changed in CEF since 2012.
There are several ways to detect when a HTML element has been selected, clicked, etc.
You can use a JavaScript event like "onclick" that calls a custom JavaScript extension. That extension would send a process message to the browser process to notify that the user clicked that element.
You can also use the GlobalCEFApp.OnFocusedNodeChanged that is triggered when an HTML element has been focused. This event is executed in the "render" process so you will also need to send a process message to the main browser process that the focused element has changed.
Use the JSRTTIExtension or the JSExtension demos as a template for your app.
They show you how to set a "mouseover" event that calls the "myextension.mouseover" function defined in a custom JS extension. The myextension.mouseover function executes Delphi code and sends a process message to the main browser process with some HTML information that is shown in the status bar.
They also have an example for a "MutationObserver" that calls a generic "myextension.sendresulttobrowser" function in the JS extension that sends the "value" attribute to the browser process.
Build the demo and right-click on the web page when it's fully loaded. Then select the "Set mouseover event" or "Add mutation observer" options to test what I described.
While executing runAppInBackground() for Android application through Appium the app gets restarted but when executed the same manually couldn't be able to reproduce the same. I Would like to deep dive into implementation of a runAppInBackground() method to reproduce the same issue in a manual way.
You need to look behind the code of runAppInBackground
From java client side (your test code) perspective, it is a single call to Appium server:
POST "/session/:sessionId/appium/app/background"
If you continue looking into where its implemented on server side, you finish with appium-android-driver function.
In short what it does:
Get current activity and package
Press physical Home button
Wait for time you provided as argument (seconds)
Bring up back in focus based on different conditions; from the code you can understand what activity is being started
Basically its a sequence of adb shell commands, that you can run from terminal.
My guess is that step 4 you did manually may differ from what Appium is doing: different activities/arguments for activity been called
I have a scheduled task that I want to run every 5 minutes.
I added the url for my method in umbracoSettings.config and the necessary settings but scheduledTasks doesn't seem to be running.
I tried debugging it by calling the url from the browser and I do hit my break point.
I tried checking the logs but there are no errors being recorded. Is this a bug in umbraco? How can I know that the scheduled task is running?
<scheduledTasks>
<!-- add tasks that should be called with an interval (seconds) -->
<task log="true" alias="task1" interval="300" url="http://localhost:43203/umbraco/api/Integration/Init"/>
</scheduledTasks>
I'm using Umbraco 7.5.8
I never had trouble using scheduledTasks in other versions of Umbraco.
The main issue I've seen with scheduled tasks is when the server that's running can't resolve the address in the task. Sometimes a server can be so locked down it can't actually "see" itself, so it can't get to the URL to run it. If this was the case though, you'd normally see some errors in the Umbraco TraceLog file in /App_Data/Logs/.
If your breakpoint isn't getting hit, you could try adding some logging code to the method you're calling and see if that gets written to the Umbraco log files? That way you should be able to tell if it's being hit or not.
Its working now. if you look at umbracoServer table in the database you will see a column isMaster.
The scheduledTasks is only running on the master server.
I use Visual Studio 2010 to debug a asp.net MVC project in my local machine. The steps are:
Click Debug and try to attch process "w3wp.exe". However it is not in the list.
I am sure "Show processes in all sessions" is clicked.
w3wp.exe won't show in the running process' unless there is actually an instance of the web application running.
Try to access your web page first, when it is displayed for the first time, try to attach your debugger. The process should now show up.
You need to click Show Processes from All Users at the bottom of the Task Manager list. This is what i needed to do.
Restart IIS
Right click your site >> Manage Website >> Browse
Back into Visual Studio refresh the processes list
Try to check on :"Show Processes for All Users"
When on the 'Attach to Process' window in the bottom left there is a checkbox 'Show Processes for All Users'
An easy way that works ,when w3wp dont appear in the list,open a browser and write localhost ,then enter.After that w3wp appears to list.
Just because an IIS application pool is started, there may not be an
IIS worker process w3wp running. IIS will not start the worker
process until the first web request is received.
In my case, I first launched the application, still could not find w3wp.exe. Then I took the worker process ID from (IIS->Worker Process -> Process Id) and then search by id in the details tab and found it.
Clear the Solution
Rebuild the solution
Reset the IIS by writing the command iisreset in command prompt
Go to IIS and browse your website
Run VS as administrator
Tools -> Attach to process -> Ensure the 'Show Processes for All Users' checkbox is checked -> w3wp.exe
Attach to w3wp.exec
If you are using something like Advanced Rest Client to test routes, call your route again then refresh the list of processes and it will show up
GoTo Web Project properties -> Select (Web) on the left sidebar -> GoTo under (Servers) header -> Click to dropdown and select "Local IIS"
and apply. Then, when you start debugging you will see w3wp.exe on the proccess list.
I just ran into this issue - you may want to also double check your host settings and verify that you are actually pointed to localhost and not a production server.
I forgot I was pointed at a remote server, and thus, though I was accessing the site, it wasn't anything local so w3wp wasn't running, despite my superficially being able to see the site running.
In my case, I have not opened the Visual Studio in Admin mode that is why the w3wp.exe was not showing on the list.
When I opened the Visual Studio in Admin mode, it worked.
Right click on Visual Studio -> Open in Admin mode.
In my case, once I rebuild the web project and raise the limit of Connection Time out (in seconds), it automatically shows in Debug/Attach to Process list and keeps working.
I would just like to share my experience as well for future readers.
Be aware that, in the event that you have a web server cluster configuration (for load balancing etc) the w3wp process might not start on the same machine that you expect it to.
Unless your website is configured to only run on a single IIS instance, the w3wp process might be spinning up on one of the other machines inside of your web cluster.
This might be faulty configuration from the networking team/department or intended behaviour. I don't have the neccessary experience to pin point exactly how it should be configured.
Found a related page on MSDN as well:

In my case, I needed to connect from one Visual Studio to the process which running from another VS studio window.
The problem was next: one VS was launched with Administrator permissions. For resolving that issue you should launch both VS with Admin perm.
In my case, the problem was that I wasn't running Visual Studio as Administrator. My machine had restarted after an update and relaunched all the previously running processes, but had only relaunched VS in non-admin mode. When I restarted VS in admin mode, the w3wp.exe processes were available again for debugging.
Run the remote debugger as an administrator.
I followed every suggestion to resolve the issue, but it was not until I ran the remote debugger as an administrator that I was able to see the w3wp process
Try the following steps:
Create a virtual path from Solution Explorer.
Go to inetmgr to confirm that your own pool is created.
Go to Attach Process (Ctrl+Alt+P) and show processes for all users.
Then you will see w3wp.exe will be there.
Be aware that even after jumping through all these hoops (kicking off an instance using a web browser, starting your remote debugging session as an admin, ensuring that "show all users" is checked, etc., ensuring you aren't on a server farm, etc), you may still at times be out of luck.
There are times when the remote process, usually a WCF service in my case, simply will not show up in the list of processes to attach to, and there's nothing that can be done about it. I'm always careful to make my target process readily identifiable by keeping it and only it in a certain App Pool. Sometimes you just can't get there from here. This is undoubtedly the most frustrating thing about remote debugging Microsoft has ever done.
my answer is late for sure, but maybe my answer will help someone.
Go To IIS.
Application Pools.
Advance Setting.
enable 32.bit Application.
Make your Application Running Under enable 32.bit Application.
Whenever a specific Windows service fails I want to run a program I've created myself. However, I simply can't find a way to make it fail on purpose, so that I can actually test that everything works correctly.
Note that the service in question is not something I've written myself, so I can't make it fail programmatically from inside the code. I wouldn't, however, mind writing a program that can make a service fail.
Of course I would prefer just having a "Make service fail" button somewhere in services.msc ... ;)
The server I'm doing this on is running Windows Server 2012.
If you don't want to use command line :
As an admin open the Windows Task Manager, in the Services tab find the service you want to test. Right click the service and click on Go to process. The selected process (if any) is the one corresponding to your service. Kill this process to simulate a service failure.
Be aware that killing a process this way can lead to problems.
Define "fail". If you want the process to end, just use pskill or a similar tool that can terminate a process elevated (as an admin).
