Overriding operators has to be done inside the class.

First of all, it should be public class Person : IEquatable<person>. You're equating one person to another not a list of people. To override the == operator, just use something like this:

public static bool operator ==(Person lhs, Person rhs)
{
if (lhs is null)
{
if (rhs is null)
{
return true;
}

return false;
}
return lhs.Equals(rhs);
}

When you step through your code, which line breaks?

:D

Colour me surprised.

As Griff has said, the bugs/suggestions forum is the place to ask. On a separate note, you should never post your email addresses onto a public forum. That is just asking spammers to target you. I have updated your question, and changed the tag from C++ to CodeProject.

An alternate approach would be to play around with console.trace (there's also an Error.trace option if that doesn't work for you), which produces the stack trace. As long as you aren't mangling calls using something like webpack, you should be okay here.

Congratulations.

Post your base images (without the text) on a picture sharing site and put the image link in your code pen. Unfortunately, I'm not looking for work.

Note: If you want to see what you've got installed as 32 bit, on a 64 bit machine, you can shell over to the 32 bit powershell using Start-Process -FilePath "$env:SystemRoot\SysWOW64\WindowsPowerShell\v1.0\powershell.exe" and then rerun the command above.

I really like Powershell.

It's the version of the OS you are running on. So, if you run powershell on a 64 bit machine, and run that command, it's telling you what's installed for that architecture.

So, to be clear, you have a 64 bit machine, with the application compiled for 64 bit, and you have installed the 64 bit driver. One way to test this is to run this command in PowerShell:
(New-Object system.data.oledb.oledbenumerator).GetElements() | select SOURCES_NAME, SOURCES_DESCRIPTION
On my current machine, this gives me the following:
SOURCES_NAME SOURCES_DESCRIPTION
------------ -------------------
SQLOLEDB Microsoft OLE DB Provider for SQL Server
MSDataShape MSDataShape
Microsoft.ACE.OLEDB.12.0 Microsoft Office 12.0 Access Database Engine OLE DB Provider
Microsoft.ACE.OLEDB.16.0 Microsoft Office 16.0 Access Database Engine OLE DB Provider
ADsDSOObject OLE DB Provider for Microsoft Directory Services
Windows Search Data Source Microsoft OLE DB Provider for Search
MSDASQL Microsoft OLE DB Provider for ODBC Drivers
MSDASQL Enumerator Microsoft OLE DB Enumerator for ODBC Drivers
SQLOLEDB Enumerator Microsoft OLE DB Enumerator for SQL Server
MSDAOSP Microsoft OLE DB Simple Provider

From that, I can see the 64 bit driver is installed. What do you get when you run this check?

If your ListView is in your main form, then yes. And don't worry about your English, it was good enough to get the question across.

For a start, update your code sample so that it actually displays the images. You can't use local file paths because we can't see the images. When you have done that (i.e. showed the images on the online example), come back and let me know. I'll take a look then.

I was just typing up an answer where I questioned the installed Chrome dev tools part, then I noticed your comment. My answer is now removed because this comment summarises things perfectly.

I like this solution. Definitely worthy of a 5.

Excellent. I'm glad I could help.

It would help if you actually showed us what your tables look like, as well as what the data is. This post requires us to make a lot of assumptions, which you could easily resolve by providing more detail, especially as the total_count appears to be a count category entries rolled up to the top level. That really looks like you are mixing concerns there - getting the query to retrieve data in a format that looks tabular with summary information.

What you haven't addressed is how the connection is being established. I could make assumptions that you are using HTTP calls, but you might have decided to adopt something like protobuf. That's going to have a lot of bearing on the techniques you are using to keep the connection alive in the first place.

My example was just to give you an idea of what you would need to play around with. As I said, I didn't have your source image so I wasn't going to be able to lay it out exactly for you. By playing around with the transform and the left margin, you should be able to achieve what you want. It might be something like this:
.about-us-text {
position: absolute;
top: 50%;
left: 750px;
transform: translate(0, 50%);
text-align: left;
padding: 20px;
width: 30%;
}

When you are trying something that is new to you, it is generally better to start off with small changes. What I would try, if I were you, would be just writing the string Hello World to the paragraph directly. Ignore reading the bytes for the moment. Just start small and make sure that the Pdf document generates with fixed text first.

While you have opened up a PdfDocument, and created a Document, you haven't added a Paragraph to the document - write your text into the paragraph, and then add the Paragraph object to the document. Have a look at an example like this: https://www.tutorialspoint.com/itext/itext_adding_paragraph.htm

Unfortunately, there isn't. The server controls what is available for download.

That's why I said it doesn't have to be accepted.

Personally speaking, I'm fine with you posting the solution as an answer. You don't have to accept it, the simple fact that you've posted it should be enough.

Thank you.

Oh crap. I hadn't realised that. Thanks for the heads up.

You need to add the id for this to match.

You are most welcome.

I'm glad you got it solved. It's definitely an odd one.

You are most welcome. Good luck.

You are still trying to turn this into a number. It's not, so don't treat it as such. Remove the call to Number.

I'm glad I could help.

The Github page I linked to has practical examples of using the NuGet implementation. Simply import the package, and follow the documentation to craft the result you need.

There's no automatic way to do the update. You're going to have to fix this manually and run regression tests to make sure that it's behaving the way you would expect.

But have you tried profiling the application? What is the hotspot? Ultimately, you are going to reach a point where you aren't going to make the code any faster, but you have to look at the profiling first.

Are you trying to maximize it as in pressing F11 (Full Screen) maximize, or does Chrome start minimized?

Reduce the initial batch size for batches to 100 and try that.

I found an example for you here. https://developers.google.com/codelabs/building-a-web-app-with-angular-and-firebase#10

It sounds like you're trying to pass this work off as your own. What legitimate reason could you have for doing this?

My pleasure. It's easy to miss.

Thymeleaf still needs code. Check this article for an example. https://www.baeldung.com/spring-security-thymeleaf

Well, that's some gnarly voodoo right there. A 5 for adding something else to my arsenal.

What is hacm? We can't supply answers without context.

Without knowing what the data underneath looks like, I can't really help there. Bear in mind that's a different question to the one that you actually asked.

Very nice. I'll load this into my repertoire now.

Break it down and try to solve one problem at a time. Concentrate on the first case, where a word changes by a single character. Try the example there first, and when you have fixed that, try another word; where a different letter changes (e.g. LEGO to LOGO). Take out the code that you think doesn't have any relevance to this, which will make your life easier. As you step over the code, look at the values of the variables to see if they match what you would expect them to.

Sounds like you want to also implement a VARIANT type of entity. https://learn.microsoft.com/en-us/windows/win32/winauto/variant-structure

My pleasure. I look forward to the article.

Excellent advice, and a timely warning that NuGet isn't always a clean playground.

You are most welcome.

Thanks.

I noticed something about your controller - I have updated the answer to query why you aren't using SqlParameters in your call.

I've just gone back to another project I was working on. Username is correct if you're using EntityFramework; but it appears that you're trying to use EntityFramework and direct access here. If you are, why are you mixing these together? Here's an example of a context class that I use with an EF project:

using Microsoft.EntityFrameworkCore;
using Qip.Models;

namespace Qip.Server.EntityFramework;

public class QipContext(IConfiguration configuration) : DbContext
{
private readonly string connectionString =
configuration.GetConnectionString("Qip") ?? throw new ArgumentException("Connection String");

///

/// The release labels.
///

public DbSet<releaselabel>? Labels { get; set; }

public DbSet<project>? Projects { get; set; }

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder.UseNpgsql(connectionString)
.UseSnakeCaseNamingConvention();
}

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
OnModelCreating<releaselabel>(modelBuilder);
OnModelCreating<project>(modelBuilder);
modelBuilder.Entity<releaselabel>().HasIndex(p => p.Label);
modelBuilder.UseIdentityByDefaultColumns();
}

private void OnModelCreating<t>(ModelBuilder modelBuilder) where T : ModelBase
{
modelBuilder.Entity<t>().Property(p => p.Id).ValueGeneratedOnAdd();
}
}

Using it (in a minimal API controller) is as simple as this:

labelsVersion1Api.MapPost("/label/{label}", async (QipContext context, string label) =>
{
ReleaseLabel releaseLabel = new ReleaseLabel { Label = label };
context.Labels!.Add(releaseLabel);
await context.SaveChangesAsync();
return TypedResults.Created("/labels", releaseLabel);
}).WithName("PostLabel").WithOpenApi();

Your error handling is attempting to check the result of closing the connection, not executing the insert.

You get error code 1062 back. Check the error immediately after you make the insert statement and you should be good to go. You need something like

if (mysqli_error() == 1062){ tell the user there was a duplicate }

Note, you should use define a constant rather than use the magic number of 1062.

If you're thinking of issues around metro and symlinks, this article show you what you need to do to resolve it https://runreactnative.dev/posts/pnpm-react-native

You answered me as I was adding - I really wouldn't be recommending COM; I would rather use something like Protobuf.

I must admit, I didn't even think of that. As always, you're correct, this could be a useful article.

I guess he wasn't :)

He already asked this question earlier this week.https://www.codeproject.com/Questions/5383289/Can-someone-suggest-me-some-nodejs-packages-or-wor

You already asked this question at https://www.codeproject.com/Questions/5383289/Can-someone-suggest-me-some-nodejs-packages-or-wor. Please don't open new questions when you have one already open.

Honestly, the admittedly sucking location you currently have, there's not a lot more you can do. You could combine the location with the genus to pick possible matches, but that's as close as you are likely to get.

I don't think you can solve this problem. Suppose my neighbour and I both have alpine herbs, and we grow them on opposite sides of a fence. How could you tell which was mine, and which my neighbours? Even image recognition isn't going to help you.

The best you could do is probably going to be a report image option, and that's assuming you have people ready to deal with the deduplication remediation effort.

Why have you hunted out a 9 year old question to answer?

Looking at the documentation, this is for portable devices only. Everything you need is under here. https://learn.microsoft.com/en-us/windows/win32/api/mswmdm/nn-mswmdm-iwmdmdevice

What error do you get back? Without knowing this, we can't really help.

My pleasure Mike.

You are most welcome.

Have you attached a debugger and attempted to run it yet? Have you read the full text of the error message to see if it gives you hints?

Dammit. I normally check. Thanks Richard.

You're welcome. I'm glad it's working for you now.

What error did you get?

You are most welcome.

The Github repository that this code comes from has documented this code. https://github.com/Jazea/Onvif.Core

Well spotted. This is what happens when you code in the Codeproject editor rather than an IDE.

You put a function call inside your main function. Move the function before main, and then call it from inside your main function.

So, what you are really asking for is:
Header: string
Body: Multiple lines.
Footer: number

Is that correct?

It wouldn't surprise me.

You are, of course, correct. This is what happens when you answer a question from memory.

My apologies, the reason you aren't able to handle this here is because you are listening for the wrong thing. What you need to do is add an event handler for the offline event on the window.

I'm not a Visual Basic developer so this might not be 100% correct, but you should be able to get the idea.

Public Function FindAncestorByType(Of T As {DependencyObject, New})( _
ByVal dependencyObject As DependencyObject) As T

Dim parent As DependencyObject = VisualTreeHelper.GetParent(dependencyObject)

If parent Is Nothing Then
Return Nothing
End If

Dim convertedParent As T = TryCast(parent, T)

If convertedParent Is Nothing Then
Return FindAncestorByType(Of T)(parent)
End If

Return convertedParent
End Function

Public Function FindDescendantByType(Of T As {DependencyObject, New})( _
ByVal dependencyObject As DependencyObject) As T

Dim child As DependencyObject = VisualTreeHelper.GetChild(dependencyObject)

If child Is Nothing Then
Return Nothing
End If

Dim convertedChild As T = TryCast(child, T)

If convertedChild Is Nothing Then
Return FindDescendantByType(Of T)(child)
End If

Return convertedChild
End Function

Using these calls, you can find the first instance of a particular type using the relevant call. So, if you wanted to find the DataGridCell from a child, you would call GetAncestorByType. To find the Rectangle, from an element higher in the visual tree you would call GetDescendantByType.

It's not just the cell that sits in the visual tree, it's the rectangle as well. So, once you have the cell, you have to use the visual tree to find the rectangle. Something to remember - your hunt for elements may need to be recursive.

Your image isn't set to share, so we can't see it.

Good luck with that. It's always good to bounce ideas off others.

Thank you so much young sir.

Oh snap.

I'm glad you got this working. Nicely done Anthony.

This question was answered two years ago. Why did you feel the need to post this?

Good luck.

I thank you kind sir.

That's excellent news. I'm glad it's working for you now.

You are disposing your memory stream before you leave the converter method. Unsurprisingly, this disposes the image information. Just after you call EndInit();, call Freeze(); on your image to freeze the underlying image. This makes your image immutable.

Damn it Griff, your sarcasm was much better than my answer. A 5 from me.

If it's a Nissan, they probably call it something like Sea Mist.

My pleasure. I take it that's sorted for you now.

We aren't going to write code for you. If you want code, pay someone to do it for you. You haven't actually addressed the questions I posed and that is going to lead you to an incorrect solution.

Thanks Richard. I was playing around with combinations of VLOOKUP and SUMIF's then realised this could be done with a lot less difficulty.

Congratulations. I'm pleased that you managed to get it working.

I have already told you that you need to use the index of the cell and the row index. You should be able to do this for yourself now.

Print this out and frame it. We can close the Internet now for we have reached peak perfection with your reply.

That's happening because you are using the id field in your calculation of the cell and startBook_C for the row. You need to correct your logic to use the index of the cell, and the index of the row. You should be able to work this out for yourself - attaching the debugger and stepping through this logic would have told you that.

So, you corrected the error that you were seeing before and the code compiles and runs. I know you have shared a picture but that doesn't tell me what error you are seeing now.

That got my 5.

Again, use the network tab to check what you are passing over. The error is telling you that you didn't supply idunidad, so check to see what you actually did pass across.

The error tells you, right at the top, what is wrong. It is expecting a parameter called unitid (idunidad) to be supplied, and this is missing. The server side has an expectation that a none-null value will be passed in here. If you correct this, you might get the results you are expecting. I say might because you may have missed out other parameters.

If you have a Selected property on each row of your grid, when new ones scroll into view (as long as you are still drawing your rectangle), don't set the Selected property to false. That's the easiest part of the whole thing.

It's a little bit unclear what you are asking for here. In your example, are Clear and Left methods that can be called? Are they classes? Please give us more context as to what it is that you are trying to accomplish.

In the same spirit of generosity of vote as you have shown to others, this deserves a 5.

Given that the poster has shown that they are already using iTextSharp, your answer contributes nothing.

I'm glad you got it working. Congratulations.

Yes. I just simplified the filtering for ease of example.

And the source: https://stackblitz.com/edit/primeng-card-demo-p7xb2r?file=src%2Fapp%2Fapp.component.html,src%2Fapp%2Fapp.component.ts,src%2Fapp%2Fapp.module.ts

https://primeng-card-demo-p7xb2r.stackblitz.io/

I have forked your repo and corrected it. You can find the details in my answer.

I got that, but the code sample you have in Stackblitz doesn't work so we can't correct it for you.

You set it to false in your code. It needs to be true.

So numpy has deprecated this. It's possible that will still work, just add the following:

import warnings
warnings.filterwarnings("ignore", category=np.VisibleDeprecationWarning)

It looks like you're expecting to use OData here, but the URL you are hitting looks like a plain URL with no filtering available. You need to check the documentation to see what endpoint you should be hitting and what parameters you need to pass to support filtering. We can't help you with that - only the documentation is going to do that for you.

Glad you got it working.

That's true - I didn't take as much care copying as I should. I'll correct this.

You’re welcome

You can store a class in there, so you could put whatever information you need in that.

My 5 for your more elegant solution.

This is an environment variable. If you are using docker, it should go in as an entry in your docker-compose yaml file.

What error do you get?

If an answer is going to be marked as the accepted answer, it should be this one.

I know it's only a measly 5 from me, but I wish I could award this 50 on style points alone. Very elegant.

This is true and it's such a great reply, you should add it to the question so I can award it as many points as possible and recommend it as the accepted answer.

Thank you Maciej.

I really wish I could upvote a comment.

A simple thing to do is write a class to manage the brush like this:
#include <windows.h>

class BrushHandle {
public:
BrushHandle(HBRUSH brush = nullptr) : brush_(brush) {}

~BrushHandle() {
if (brush_) {
DeleteObject(brush_);
}
}

operator HBRUSH() const {
return brush_;
}

private:
HBRUSH brush_;
};

Then, you can use the brush like this to create the brush:

BrushHandle brush(CreateSolidBrush(RGB(240, 240, 240)));

You fix it by correcting the code that triggers this exception. That's as much help as we can offer right now because you haven't given us any code. Think of it this way - we aren't sitting behind you and we haven't hacked into your hardware so we have no idea what the code is.

Okay, don't repeatedly create brushes. Store them as members instead and don't forget to destroy the object in the PostNcDestroy method.

Thank you.

Have you tried the steps here? https://uk.godaddy.com/help/send-email-using-systemnetmail-in-windows-hosting-19291

What versions of Spring Boot and Tomcat are you running here?

Thanks.

I have updated the answer based on your new requirements.

Unblocked again.

I have unblocked your question on that forum.

It looks like you're replying to Griff here. Unfortunately, as you have posted this as an answer to your question, he won't be notified of your response.

What am I missing here? I don't see any database updates in there.

I'm pleased you found it.

You have to explicitly enable server side rendering in React. It's a client-side framework by default. Angular is also client-side, and requires a connection to external services.

If you are replying to Andre, he won't be notified that you are doing so because you haven't actually replied to his answer. Don't add answers of your own if they are meant to be replies.

I'm glad to see that you sorted the problem. Just a small note - as you didn't reply to my messages, I didn't receive any notifications. If you want to reply to someone, click Reply on their message, don't post a new one that isn't connected.

When you download the file, what file name do you see?

If you have a question for Griff, post it as a reply to his answer. He will get an email informing him of your question.

You are most welcome.

This is a truly beautiful answer.

I have simplified the string. I was getting too cocky with the input and miscounted the ' characters.

That was my mistake - I copied your original code in and left the space in '\ '. I've just updated the answer. Also, if you post what you're actually getting back, that would help.

Thank you.

My pleasure.

The only way to do this would be to open the file, and transmit the individual parts of the file.

That's correct.

I see that you're uploading the file to the server. The code to change the value would have to be in the handling code at the server.

Have you checked that the service is still set to auto-start on the server? Setting the start type to Automatic only applies during the registration of the service. This doesn't override someone else changing the value once it has been installed.

What you're probably going to be looking for is OpenIDConnect (OIDC). This sits on top of OAuth, and gives you access to authenticate and gather profile information. See https://learn.microsoft.com/en-us/linkedin/consumer/integrations/self-serve/sign-in-with-linkedin-v2 for further information.

Do you get any response back when you issue the fetch, does it return bad data, or does it just hang? Right now, there's a lot going on in that code and you're asking us to guess which part doesn't work.

I like it. Have yourself a 5.

If you are asking a question, don't hijack an old answer, add a new question.

Thank you.

I'm not sure what optimisations have been put in place in CArray since I last used it. This approach was one I have used since the mid 90s, going backwards when removing items to avoid *clever* compiler tricks.

That's a given.

Sounds like something that should be on a range of bumper stickers. "Warnings are for wimps". "Exceptions are for a**holes".

You are most welcome. I am a big fan of ETL tools.

I'm glad you got it sorted.

Thanks Richard. I hadn't noticed that this was a resurrected question.

Thank you.

You should raise it from each property. The key to using this event is knowing that, if you raise the event with the property name as an argument then the binding engine knows the name of the property that changed. If you leave the property name as an empty string, the binding engine thinks all properties have changed.

5 from me.

Are these services deployed as separate Spring services or is it all in one service?

This is all part of the WiX v3 toolset which you can find here. The documentation listing the tooling is here.

A 5 from me.

This has already been solved. Why are you adding to this now?

Thank you so much.

I was just coming here to answer this very thing. I'll not bother now because this you answered this with a version of the answer I would have given. A 5 from me.

Thank you kind sir.

You should post a version of this as the answer so it is removed from the unanswered questions list and, more importantly, so that I can vote for your answer.

My apologies. As I said, I was doing this from memory. The API I was thinking of was this one. https://learn.microsoft.com/en-us/windows/win32/api/timezoneapi/nf-timezoneapi-systemtimetotzspecificlocaltimeex

That's great. Thanks for letting me know.

You don't show the code that actually opens the file here. What does that code look like?

Have you followed the link yet? This is a cad library that gives support in WPF for Autocad display.

Which version of Go are you using?

It was my absolute pleasure.

You can use Dog without registering it - I was just demonstrating that you didn't need to create an interface just to register a concrete type in the container.

Succinct. I like it.

Your question doesn't make sense to me. If you want to zip it up, you could do this yourself. What are you really asking for here?

You are most welcome.

The stack trace clearly shows the line that the error occurs in PageNavigationService. What is happening on line 808 and line 815?

What does "can't seem to get working" mean? Are you not getting data back? Is one field populating, but not the other? We can't see your screen so we need additional information if we are to help.

Don’t use void on async methods, they hide exceptions. Use Task as the return type.
