The question is:
Do you seriously want to learn how to become an IT specialist, who can code, or are you more interested in the party type student life.
The problems you want resolved are quite trivial, and I could easily write you the required lines.
However, I will not! You seem to be early in your course. I have no doubt that your college provided you with the resources required where you can find out how to write this code. Read it, and Try it out, fail and Learn. Writing Code is about Trying and Learning, the whole time. You write the Code, Compile it. You get Compiling errors. That means that the Compiler does not understood what you wrote. Solve them, it Compiles. Now you have a running program or App. Does the App do what you want it to do! Very Often it does not. They call that Debugging!
I learned C and CPP/MFC the hard way. By myself, trial and error. My University simply did not have a computer that students could work with in 1974. My first computer was a Commodore 64 in 1985, where I learned the beginnings of Machine Code and ASM programming. A small PC with a C Compiler came as a godsend, and at the time I was in no doubt what compilers linkers, and debug/retail versions did and could do.
You have an institution with resources behind you. Use those resourses and learn. Stop asking this forum to resolve your exam questions.

Hi!
I am pretty new to this, but im trying to present when the latest winupdate was done on computer, and only found in powershell to present that, and i tried to run it in C#, but no error and no result.
I understand that im doing wrong, but what is the best way to do this?
private void LastWinUpd()
{
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();
PowerShell ps = PowerShell.Create();
ps.Runspace = runspace;
ps.AddCommand("$a = (New - Object - com 'Microsoft.Update.AutoUpdate').Results");
ps.AddCommand("$a.LastInstallationSuccessDate | Get - Date - Format 'yyyy-MM-dd K'");
Collection<PSObject> results = ps.Invoke();
runspace.Close();
StringBuilder stringBuilder = new StringBuilder();
foreach (PSObject obj in results)
{
text_LastWinUpd.Text = obj.ToString();
}
}

Yes, this forum is for C/C++ questions.
What happens when you run the powershell commands in PowerShell and not via C#?

As the other Richard said, you've posted this in the wrong forum.
But you don't need to invoke Powershell in order to create and use a COM object. You can do that directly from C#:
Type t = Type.GetTypeFromProgID("Microsoft.Update.AutoUpdate");
dynamic a = Activator.CreateInstance(t);
DateTime lastSuccessfulUpdate = a.Results.LastInstallationSuccessDate;
text_LastWinUpd.Text = lastSuccessfulUpdate.ToString();

Hi!
Yeah if possible i want it in C# only.
I trid the code but i gives this:
0001-01-01 00:00:00 +00:00

What do you get when you run the Powershell code in Powershell on the same computer?

2021-09-20 is the result from PS command
|
|
|
|

The Powershell script and the C# code return the same result for me. Are you definitely running them both as the same user on the same computer?

Works for me:
private DateTime GetLastUpdateSuccessDate()
{
Type t = Type.GetTypeFromProgID("Microsoft.Update.AutoUpdate");
dynamic a = Activator.CreateInstance(t);
DateTime lastUpdate = a.Results.LastInstallationSuccessDate;
return lastUpdate;
}

Hello All,
I am looking for an C code example to capture DISK IO utilization by a process. Please help me out to get the example.
Thanks.

I am looking for an API which gives DISK IO utilization of a process on windows box. Please share any information related to capture IO utilization.

Did you actually follow the link I gave you?

So what is wrong with GetProcessIoCounters function?

Hey everyone,
I'm a beginner in c++ and I'm trying to connect to my garmin watch via bluetooth. The watch is connected on w10, with bluetooth LE explorer i can see the UUID and service ID for the heartrate. I'm looking for a simple way to connect to it from c++ and read the data.
The last 2 days i've been trying even c++ builder, all kinds of libraries but can't connect.
I'm surprised i can't find simple examples online, bluetooth and windows doesn't seem to be quite simple.
Does anyone have an example on this?

So, I've gotten one stop further, I'm using this code: GitHub - urish/win-ble-cpp: Proof of Concept - BLE on Windows (for Web Bluetooth)[^]
I've put in my shortcodes for the service and charachteristic and the code manages to complete them for the right UUID's so I assume it connects!
these are the shortcodes and ID's, next up, how can i read the values from these?
auto characteristicUUID = Bluetooth::BluetoothUuidHelper::FromShortId(0x2A37);
|

|

Sorry, I cannot answer that. Once you have established a connection then the data passed between the stations will depend on the devices being used. Check the technical documents for the watch you are using.

Ok, I'm getting closer:
auto leDevice = co_await Bluetooth::BluetoothLEDevice::FromBluetoothAddressAsync(264540343013609);
auto naam = leDevice->Name;
auto servicesResult = co_await leDevice->GetGattServicesForUuidAsync(serviceUUID);
auto service = servicesResult->Services->GetAt(0);
auto characteristicsResult = co_await service->GetCharacteristicsForUuidAsync(characteristicUUID);
auto test = characteristicsResult->Characteristics->First();
auto characteristic = characteristicsResult->Characteristics->GetAt(0);
So firts line, i'm putting in the mac address manually, i check if the name corresponds and indeed it's my garmin. Then i put in the service and charateristic for the heart rate service. Now i'm stuck, how could I get the heart rate value out of this? I read somewhere that it's the first byte but don't know how to extract this

As I told you earlier, you need to check the documentation for your device. The format of the data it sends will only be documented by the manufacturer.

@Richard, I'm looking for people who have practical advise in this, I'm new to c++ and to everything i'm trying to do here, I've been struggeling for days. There is also not a lot to find on the internet regarding this. If you don't know the answer that's ok, you don't need to answer. I'm not posting on here to get 'check the documentation' answers.
|

|

As I keep pointing out, the format of the data that will be presented by the device is specific to that device. So the only way to find out what it is, and what format it is sent in, is to get the technical documentation for the device. It is not a C++ issue.

thanks for hijacking this question, you spend days and days trying to work stuff out, put a question up for help to get this... Don't you have anything better to do? Incredible

What do you mean? I have tried to help you and I have told you where to find the information you need.

And Richard is trying to lessen that time by giving you some sage advice. This is how integrations work, if devices are spitting out data in certain format (and many times that format is specific to the vendor) it is up to YOU to determine (by looking at available vendor documentation) and code for this format.
