My understanding of this is you can use NextResult to get the next resultset. As it's a firehose, you can't go backwards unfortunately.

Thanks, Pete!

As Pete says, the reader doesn't "rewind" - so I'd probably prefer to use a DataAdapter and fill a Dataset instead of using a DataReader. That way all of the data for all of the sets is available for random access as needed.

Good point, Griff! I didn't know that option existed!

Hello,
I want to work with a File. I cant get Permission or owner.
Im not the owner of the files as i can see in the propertys.
The Path of the Files are: %userprofile%\AppData\Local\Temp
Here is how i tried to get access owner or permission:
FileInfo info = new FileInfo(path);
FileSecurity security = FileSystemAclExtensions.GetAccessControl(info);
SecurityIdentifier identifier = WindowsIdentity.GetCurrent().User;
security.SetOwner(identifier);
security.AddAccessRule(new FileSystemAccessRule(identifier, FileSystemRights.FullControl, AccessControlType.Allow));
FileSystemAclExtensions.SetAccessControl(info, security);
My goal is to open a FileStream and Write over the File, here is a exaple:
File.SetAttributes(_recycleBin, FileAttributes.Normal);
string[] files = Directory.GetFiles(_recycleBin, "", System.IO.SearchOption.AllDirectories);
foreach (string file in files)
{
try
{
File.SetAttributes(file, FileAttributes.Normal);
double sectors = Math.Ceiling(new FileInfo(file).Length / 512.0);
byte[] dummyBuffer = new byte[512];
RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider();
Trace.WriteLine("DEBUG LOG: " + file + "loaded.");
FileStream inputStream = new FileStream(file, FileMode.Open);
for (int currentPass = 0; currentPass < timesToWrite; currentPass++)
{
inputStream.Position = 0;
for (int sectorsWritten = 0; sectorsWritten < sectors; sectorsWritten++)
{
rng.GetBytes(dummyBuffer);
inputStream.Write(dummyBuffer, 0, dummyBuffer.Length);
}
if (currentPass == timesToWrite - 1)
{
inputStream.Close();
FileSystem.DeleteFile(file);
}
}
}
catch
{
}
}

Dumping a pile of code on us and saying "it don't work" doesn't help anyone: we have no idea where in that code the error might be occurring and no way to run it to find out.
To help normal humans read it, I've edited your question and added code blocks to separate the files and preserve the formatting but you should check that I didn't mess something up - particularly as your indentation is inconsistent!
We can't tell you "do this" and it'll fix it: start by looking at the error message closely as it'll tell you where in that the error occurs. You should expect to get syntax errors every day, probably many times a day while you are coding - we all do regardless of how much experience we have! Sometimes, we misspell a variable, or a keyword; sometimes we forget to close a string or a code block. Sometimes the cat walks over your keyboard and types something really weird. Sometimes we just forget how many parameters a method call needs.
We all make mistakes.
And because we all do it, we all have to fix syntax errors - and it's a lot quicker to learn how and fix them yourself than to wait for someone else to fix them for you! So invest a little time in learning how to read error messages, and how to interpret your code as written in the light of what the compiler is telling you is wrong - it really is trying to be helpful!
So read this: How to Write Code to Solve a Problem, A Beginner's Guide Part 2: Syntax Errors[^] - it should help you next time you get a compilation error!
And spending a little time learning to understand syntax error messages will save you a huge amount of time in future: you waited at least 1/4 hour for Chris to reply, then your email system probably added another 10 minutes or so, plus the time it took you to type up the question once you had found this site and created an account. Chances are that you could have saved a significant chunk of that time if you knew how to read them!
I'm not saying we don't want to help you fix them - sometimes I can't see my own errors because I read what I meant to write - but fixing syntax errors is part of the job, and if you can't do it for yourself people are going to look at you as a bit weird should you get a job in the industry!

Thank you for the reply.
And yes totally understand the lack of describing the issue and not providing the codes in blocks for each CS form. That is my bad this is not my main career actually far from it as I am a piping designer. I have very little programing knowledge but eager to learn. This is my very 1st attempt at writing C# and thought I had done good just to get to where I was.
I will try and not bother the forum with questions as much as possible. And will look at the reference information you provided.

We are fine with questions - provided you show us you have tried - just try to remember that we only get what you type! 
Use code blocks to mark code and it becomes a lot more readable - edit your original question and you'll see what I did; there is a "code" button above the text box which will do it for you.
And show us relevant fragments of you code, not the whole thing - it makes it a lot more likely that someone will read it and try to help.
Hopefully, you are on a course or following a book to learn this stuff rather than random guesses or *shudder* YouTube "tutorials"?

Well actually I am using the school of Google and ChatGTP. I did way back in 2004 take a semester of .lisp and .vba. But they really do not translate well into this. But I am probably going to look into some online learning courses. Being in Houston there is a lot of training schools and online classes.

Don't do it like that, please.
Trouble is that unless you know something exists, you can't look for it - a course or book presents everything in a structured manner so it's easier to understand, and provides exercises to check your comprehension. It also helps to "cement" the learning - we learn by doing, not by looking - you can watch as much of the Tour de France as you like, it won't teach you to ride a bicycle!

I'm putting this in C# since it's an issue with initializing NET...
I have a WinForm DLL that is written to be DPI-aware. It is called from both C# and C-based executables. There is an intermediate mixed-mode C / CLR / C# DLL between the executable and the Winform DLL that calls from C to Managed C++ to C# to launch the WinForm DLL. Both the C and the C# exe are also DPI-aware (as appropriate for their language) and both display correctly.
Here's the logic flow.
C or C# exe:
- calls into the intermediate's cdecl entry point using the usual LoadLibrary / GetProcAddress mechanism
intermediate mixed-mode DLL:
- C entry point makes a call to an internal CLR function
- CLR function marshals the parameters, does a gcnew on a C# class and calls its single member function
- C# member function:
Assembly targetAssembly = Assembly.Load (File.ReadAllBytes ("path to winform dll");
Type startType = targetAssembly.GetType ("startupNameSpace.startupClass", true);
object startLib = startType.InvokeMember ("", BindingFlags.CreateInstance, null, null, new object[0]);
startType.InvokeMember ("startupMethod", BindingFlags.InvokeMethod, null, startLib, new object[] { marshalled parameters } );
WinformDll:
- startupNamespace.startupClass is NOT a form, just a plain C# class
- startupMethod creates a parameterized thread, sets the apartment state to STA and starts the thread passing the marshalled parameters
- the thread instantiates the first WinForm class with the parameters and calls ShowDialog
So, here's the problem.
When run from a C# exe, the DPI logic works correctly. I have a C#exename.exe.config file in the same directory with the exe that contains a "startup" section with my framework version number and a "System.Windows.Forms.ApplicationConfigurationSection" section containg the DpiAwareness key with a value of PerMonitorV2.
When run from a C exe, the WinForm display is incorrect in the exact places where I have my DPI-handling logic. It's obvious from the display that the property DeviceDpi is incorrect for every form. The research I've done leads me to believe that the .NET environment created to run my winform assembly is missing the dpi awareness flag that is set in the config for the C# exe. I've tried adding a config file with all the different name permuations using the C exe name, the intermediate dll name, the Winform dll name, "exe" and "dll". Nothing is picked up by the NET subsystem that is automatically loaded for me.
So the question is -- how do I force the NET subsystem to see a config that sets the DPI state?
Judy
Also, I have tried the solution to fix an incorrect DeviceDpi when an exe is first run on a secondary monitor (in the form's OnHandleCreated, call GetDpiForWindow, scale it, resize the form, and send a WM_DPICHANGED with that retrieved dpi). Putting this in the first form displayed does not fix the incorrect display.

I'm writing a program that allows users to send commands to various serial devices. Most of the commands are "Button" orientated. By that I mean they press a button and everything is done for them; however I have a textbox that allows them to type in manual commands should there be something I don't have a button for that they really want to happen. I'm thinking about logging what commands they are typing in order to improve my program so that I can add other buttons that will help make life easier all. I'm wondering if there's a way to do that possibly on Github so that I can retrieve basically over web. Or if there's a better way to do it? I'm currently working in Csharp/WPF. I'm also thinking about logging some try/catch handler errors, so that I can analyze software bugs too, but I'm not too bothered about that right now.

First of course be aware of your user base. You are collecting information about them by doing that and there might be customer relation problems with that. And legal ones as well.
Other than that all your are doing is collecting data remotely from an application. There are many ways to do that.
geomeo123 wrote: if there's a way to do that possibly on Github
As in that there is a library for that? Or that you want the data stored on Github? For the first I am certain there is. As for the second that wouldn't be my choice.
geomeo123 wrote: thinking about logging some try/catch handler errors
You should create a code API that logs the following
- location. File/method.
- Text that describes what it is
- Additional information. This would be where you put exceptions, including stack traces.
Then you call that where ever you want.
There are specific libraries that provide 'logging'. In C# I have used log4net and Nlog.
That provides the API that I mentioned ready to go. It does not however provide the 'destination'. I know you can find addins to log to databases. I suspect others.
Another problem you will have is that since your application is remoting pushing data then someone might do something malicious to abuse your system. Basically you need to figure they will attempt this. So at a minimum you need to provide credentials. Although that probably is not enough. You might want to throttle as well so if they hack your app they can't just start blasting away.
There are services that provide APIs that collect data also.

I don't think he knows. Think we might have to go to a university and earn a degree to figure it out.

Ah, Log4Net. From the glory days of .NET, as I moved from (work) place to place everyone used it. Seems to have lost favour in the Core world, and been replaced by something more standardised and flexible, but not as to-the-point 
Two line logging, whoever thought that was a good idea?
Regards,
Rob Philpott.

I use Winform and I use Entity Framework to communicate with the database and I use the MSSQL database and when I want to connect the SQL database to the Visual Studio program, the table Those that exist in my database are not present as classes in the Visual Studio program
|

If you're talking about using the Data Sources tab in Visual Studio to connect to the database, and you're using Entity Framework, you're doing it wrong. The Visual Studio designers will not create classes for Entity Framework. You have to write the classes yourself.
