I just ran your code on my machine (XP) and all values were retrieved.
I also tried retrieving the value of ProductId and this also worked.

I believe in XP the ProductId is in the Windows hive (not Windows NT as in Vista and Win7).
Do you have an entry for ProductId in the Windows NT/CurrentVersion/?
<edit>
I re-read your post and see that you do. Now I am confused.
</edit>
If I remember correctly in XP it is under Windows/CurrentVersion/ or possibly a hive under that.
Thanks for checking it out.

Without knowing what you're using for sensors and how they are connected to your machine, anything anyone posts could be worthless garbage. Such as, what radio types are you using? Are you using a mesh network? What protocols are you using? ..., ..., ...
Are you looking for the code to run on your PC to capture the data coming from the remotes? Are you looking for code to run on the remotes (which, BTW, won't be C# unless they run .NET Micro Framework)??
And since this is a school project, the chances of you being handed code are very, very slim.

The device you're using should come with instructions, or driver software/an API which you can connect to. You can use SerialPort[^] if it's a serial device, or you can use P/Invoke to get at the parallel port (for example this excellent article[^]) if it's a parallel device.
If there's an API available, use it, possibly through COM interop or P/Invoke declarations if it's an old school DLL.

Greetings Gurus,
I need an event to fire at set times during the day from a Windows service.
Code so far
protected override void OnStart(string[] args)
{
if (DateTime.Now.TimeOfDay == System.TimeSpan.Parse("09:00:00"))
do something
but I would like it to run at 13:00, 17:00 & 21:00 too.
What is the correct syntax please as I can't find any examples of how to do this. I don't want it to run every 4 hours (e.g. 01:00, 05:00) so I would prefer not to use a static schedule.
I would also like to add an event log entry if the service didn't run at the scheduled time so that it could be investigated but am not sure about how to go about it.
Could you help please?

I've done a similar process in the past by setting up tasks on a background thread that get run at the appropriate time. These threads are then put to sleep until the appropriate point, when they wake themselves up and perform their task. Upon completion, the thread is put back to sleep until the same time the following day. The beauty about this approach is that the only loop you need to put in place is the one that kicks it off in the first place, and closing down the service should just involve shutting down the sleeping threads.
When I wrote this, I used a Mutex and based the sleep interval on a TimeSpan.

Don't use equality tests on (almost) continuous types, such as DateTime, float, double. Two independent values will hardly ever be equal, DateTime may have a resolution of 1 Tick, i.e. a tenth of a micro-second. Either use a simple greater-equal test, or perform an interval test.

What I have done in the past is to have a Windows Service cycle every second or ten that scans a database table for tasks that are due and runs them.

That's just silly. Why log something when it could run the task instead?

Hi, I have a panel and custom controls on it. I know how to select multiple controls by clicking on an empty space on the panel and move the mouse but how can I do it if the panel is covered fully by controls and not visible?
All I want is to click on any of the controls and drag the mouse on the other controls to select them. Any clue would be appreciated.Thanks

Does Ctrl+Mouse-click work?

Thanks I did Ctrl+click, it works but I also want my users to select the controls with only one hand
|
|
|

In that case you really need free space to start your mouse drag.

Thanks, at least I won't spend my time for a thing which is not possible.

Just curious: I assume you are speaking here of "your users" as "design-time" consumers within Visual Studio ... where they have your Panel's source code within their own projects, and can manipulate any object inside the Panel, delete it, move it, etc., ... ? And the controls within your Panel (via use of Dock and Anchor) completely fill the Panel ... so if the user did resize it no Panel surface would be exposed ?
best, Bill

No, I mean runtime users

Hi, Now that it's clear this is a run-time scenario: curious to know if your goal is to have a visible selection rectangle appear, and for controls to visually indicate their selected state.
Have you considered an alternative selection mechanism, such as a pop-up window that has TreeView with CheckBoxes where the Control hierarchy can be represented ... perhaps selected from a custom context menu ... that could possibly still enable you to stay in 'one-handed' mode ?
Have you written your selection code already ? Are you still interested in pursuing this ?
best, Bill

Yes I did but not the way I wanted.
What I wanted was to click on a control and move the mouse to the others (with the help of a visible selection rectangle) to select the controls which intersect with the selection rectangle
What I did : I click the panel that contains all those controls (with a selection rec. visible only on the panel not the controls) and move the mouse.Intersection with rectangle logic is same
the point is I don't want to enlarge the panel to leave a clicking space for selection.The panel should be invisible behind the controls

what is in those files? are they executable (EXE, DLL), source files (C#), or something else?
You can load DLLs dynamically, call native code using P//Invoke and managed code using reflection.
You can compile C# files at run-time, the necessary tools are part of the .NET framework.

It could load plug-ins if you tell it how.
