Hell what are you talking about?
How can we know what you have in mind ?
If I understand what you want, the answer is this kind of magic does not exist.

Asking questions is a skill[^]

“Everything should be made as simple as possible, but no simpler.” Albert Einstein

If you want to control certain physical parameters of a CPU, GPU or RAM then you will have to look for some motherboard-specific driver software with a documented API. Pretty sure there won't be a single one based on .NET so you would have to use P/Invoke or a C++/CLI-wrapper provided that it was your intention to ask for this in the C# forum.

If you want to control physical parameters of other circuit board components by software (since you mention capacitors) then the circuit board would have to be designed for that purpose as well, meaning it would have to have components dedicated to interface with your software and with other components to allow your software to control those other components. So it absolutely isn't possible to do this with an arbitrary circuit board, especially not just by knowing its coordinates..

If the brain were so simple we could understand it, we would be so simple we couldn't. — Lyall Watson

Please update when you find this libary

Why should Sascha find this library for you?

This space for rent

As Sascha noted, it is essentially impossible in the general case.

How is it impossible?

The software does not care about the details of the motherboard. All non-standard hardware comes with software that knows how to talk to that hardware, aptly called "drivers".

ON SOFTWARE

Software can only process signals from hardware. It's not magic.

There is no such thing as "completely standard hardware" in the PC world: all PC's are assembled using a huge number of possible components. Your example is spectacularly wrong: there are Intel and AMD versions of the "basic" processor, each of which has a large number of different processors in it's range. And to read the processor temperature is different in each family!

So the OS has a API which works out which processor it is, and reads the temperature appropriately - but it looks like a simple WMI request to your application (most of the time, sometimes the motherboard design makes it unavailable) because the OS "hides" the hardware from your application. That is part of what drivers are for: to interface between the hardware (or a virtualisation of the hardware - don't ask, just don't) and the OS so that the hardware maker can communicate in a way that the OS can understand, and interpret for the applications.

It's a bit like your car: it has a fuel gauge, but you have no idea how that gauge actually works or how many litres of fuel it is showing - and you don't need to know as long as you can glance at the dashboard and see you have 1/3 tank left.

So software if sits on top of the OS enabled through drivers and underlying to access but all is encapsulated in the OS so to software it is the same so one code to examine physical component of the motherboard the same regardless of individual hardware

so to read temperature of component onw libary is good

That's the whole idea - the application doesn't get to look at the hardware, any more than you have to physically look at the sensor in your fuel tank! The OS and the drivers each provide a layer of abstraction that prevent your app getting anywhere near it.

Completely standard hardware does not have to include the sensor.

If it is, it will be conforming to a standard. If Windows supports the sensor, then you can query it using the Sensor API introduced with Win7.

Thanks

I've worked with a format called Gencad for this. The Gencad file specification is available somewhere on the Internet; once you get it, you need to read the CAD file based on this spec, and then render the different PCB elements on the screen using GDI kind of commands.

Had developed a Gencad viewer, and this is property of one of my earlier employers.

i have this code but it's giving error(the name ZipFile doesnot exist in the current content) because of framework 4.5.1

using System;
using System.IO.Compression;
{
const string ZIP_FILE = @"C:\temp\test\temp.zip";
const string ZIP_FOLDER = @"C:\temp\test\";
using (ZipArchive archive = ZipFile.Open(ZIP_FILE, ZipArchiveMode.Read))
{
foreach (ZipArchiveEntry entry in archive.Entries)
{
entry.ExtractToFile(ZIP_FOLDER + entry.Name);
}
}
}

See the Remarks section at ZipFile Class (System.IO.Compression)[^].

Import below namespace
add a reference to the System.IO.Compression.FileSystem assembly in your project, it will resolve you issue,
basically 'Compression' namespace is introduced in framework 4.5 and above

In crystal reports i have used xml file to display the data. the fields are displaying but data is not displayed and parameter filter is also not working.

Below is the code:

           frmRpt.crViewer.ReportSource = myrpt;
           frmRpt.Show();

Please help me in resolving the above issue.

Thanks

First off, don't do it like that.
Do not concatenate strings to build a SQL command. It leaves you wide open to accidental or deliberate SQL Injection attack which can destroy your entire database. Use Parametrized queries instead.
Fixing that will very likely fix your other problem as well (and make you code more readable)

Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

You have already posted this question in QA:

That's the most likely culprit - you start a new thread to perform a long-running operation, and then immediately block the UI thread until your background thread has completed.

Try using a BackgroundWorker[^] instead.

Thanks Homar...Just I need one more help:
below are the steps which I did:
1)created 5 backgroundworkers and it runs parallely.
2)crated one function to write the logs
3)created one public string veriable as "myLogText".
4)called the write log function in each background worker to write the logs
5)passing myLogText string in write log function
6)once run the program, app creates the log files backgroundworkerwise and write the logs but I realised that texts are mismatching..that means one log file created by backgroundworker1 but in text file text content are there from other background worksers also

please help me ...

Without seeing your code, I can only guess that you're trying to update a single string variable from multiple threads.

Either use a different string variable for each BackgroundWorker, or pass the log messages to the ReportProgress method[^] and update the variable from the ProgressChanged event[^].
