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.

Perhaps put a link to the nuget package that you have downloaded.

5 from me.

What error do you have? Saying you have an error is next to useless if we don't know what the problem is.

It's my absolute pleasure.

I have to ask. What type is PermitID in your C# code?

Is your tag right? Are you really looking at optimising HTML.

If you're looking for Laurent's implementation, you can find his archived GitHub version here. https://github.com/lbugnion/mvvmlight/blob/master/V3/GalaSoft.MvvmLight/GalaSoft.MvvmLight.Extras%20(NET35)/Command/EventToCommand.WPF.cs

No need to apologies. I saw that it hadn't been answered and thought "better late than never".

Have you looked at the logs in the site to see what's happening internally? That would be the best place to start, when you are trying to diagnose an issue like this. There could be many, many reasons why this is happening (from missing header information, incorrect agents, through to authentication issues), and the logs should give you more of an idea about what's actually going on.

Thank you.

When you put a breakpoint in GetCategories, what values do the parameters contain?

Which library are you using to read the document with?

You don't have any code for accessing the camera here so how can we tell you what's wrong with it? I can see the placeholder where you wanted to add the ability, but that view is just an empty bit of placeholder comment right now.

We aren't going to write your code for you. We aren't doing your course, so why should we solve your homework for you? You should have all the knowledge you need to solve this; if you don't, approach your tutor to get help.

And have you used a dependency checker to see if there are other missing dependencies? https://www.dependencywalker.com/

Did you copy the 32 bit DLLs into the build output directory and try that?

Then why does your question say that if errors in the loop?

What error does it give? That's a rather important clue missing to what is going wrong.

Try your query out in MySQL directly. If things don't work when you try them through your application, check the query in the actual database itself. Also, change the query to this:

SELECT * FROM tbdata_reservasi WHERE tanggal_masuk >= @ST AND tanggal_keluar <= @ET

Copy and paste that line in directly. You had quotes in your original query, and they weren't needed.

One final thought; what data types have you used in the database for tanggal_masuk and tanggal_keluar?

I think we can guess the answer to that.

Do you know where in this code that it triggers the denied access operation? You have a number of lines of bluetooth code in there; knowing which one throws the exception would help diagnose the problem.

You're coming across as very hostile in this post. You could simply have moved on, but you've chosen to be angry and make this personal.

What is the if statement in your validateUser method? The condition is missing in your question.

There are so many things here that mean you aren't going to get any help. First of all, we don't build systems for others, for free. Most members are professional developers, so expect to get paid for their efforts. Second issue; you have a scattergun approach to the languages involved, so we don't know what language you are expecting. Third, if you have tried to build this system, you should tell us what parts didn't work - we might be able to help you with those. Make sure that you are detailed in those posts; saying it doesn't work isn't enough. Show us code that reproduces the errors you are facing, tell us the exact problems you are seeing, and tell us what you have tried so far, to fix it.

Just as a matter of interest; your form isn't set to Always On Top is it?

Have you looked at the error information? Print this out in the catch block so you know what is causing the error.

I understand that it's tempting to come here and ask the people who answer on the site to do your work for you. You have to understand that no one is going to do that for you; people do not like it when others demand that they provide the work.

A disconnect does not trigger an exception - it's just an error code. What you need to wait for, is for the async call to time out. Once you get the timeout, EnsureSuccessStatusCode() will trigger an exception. If you want to reduce the timeout on your HttpClient, you can specify that as an option. I believe the default is 100 seconds.

Don't abandon it. It's a fun little challenge and one you should definitely do. Try breaking it down into smaller chunks and solve those.

It would help if you could explain, further, what you were trying to accomplish. Are you trying to intercept mouse clicks on the clock widget?

Okay, so the problem you have here is with having a version of Excel registered that cannot open .xslx format files.

Put a breakpoint at the start of your code and step through it line by line to see which one throws the exception. I have a suspicion you're going to hit it on ReleaseComObject but you need to verify this. If you are just trying to close your application there, you just need to call application.Quit(); rather than ReleaseComObject.

This, as far as I'm concerned, is the correct answer.

You are most welcome.

What link are you trying to download? Remember, while you know what you are talking about, without providing clear and detailed thought processes, we have no context to help you here.

You're most welcome. I'm glad you're up and running.

Your onclick is doing return false.

How much data are you trying to load?

Are you trying to show the status result of a request here?

How can we help you? We have no sight of your code. We don't know what errors you are getting?

Are you trying to prevent it from being moved again? So, once it's dropped, that's it - it can't be moved ever again.

There are plenty of examples here. https://www.google.com/search?q=datetime+tryparse&oq=datetim.tr&aqs=chrome.2.69i58j69i57j0i10i30.7243j0j7&client=ms-android-samsung-gs-rev1&sourceid=chrome-mobile&ie=UTF-8

I guess I was the last report. He's outta here now.

You can do that as well. I'd be tempted to host a RESTful API on the server and interact with the database that way, if I were writing this.

My 5

What is your actual question? You have just dumped code.

Got my 5.

Richard's answer below shows what you need to do. The problem you had in your code is the process expects d:\GIT\proj1\GIT to be a runnable command whereas what you are actually trying to do is run GIT (which is in another directory) inside the d:\GIT\proj1 folder.

You said you the code doesn't work but that doesn't really tell us anything. Are you getting errors? If so, what errors are you seeing?

The beauty about process commands is that you can try them out without having to run the application. What do you get when you run the d:\GIT\proj1\git pull master command?

Thanks

There are a few paid for components that can do this for you. I've not seen any open source versions that would allow you to do this.

You're not an idiot. Sometimes it just takes explaining a problem to someone else to see it.

What do you mean when you say it doesn't work? What are you expecting to see when you run it?

Your API would look something like this:
[HttpPost]
public IActionResult Post([FromBody]EmailMessage email)
{
// the email message here should match the email you posted in your console
return Ok();
}

Why are you doing async with GetClient? That doesn't need to be awaited.

My 5

Nice.

I have indeed. It's pretty straightforward.

This works equally well on Linux solutions (I do this myself). When you publish, just set Linux ARM64 as your target.

Thanks

I just mocked this up and it works perfectly for me. Perhaps you should share your code as to how you added the forms to each other.

What code do you use to close Form3?

So many answers, so many of them unsuitable.... :wink:

Sorry I haven't had a chance to respond before; IHttpClientFactory is normally injected into your code if you are using .NET Core and uses the DefaultHttpClientFactory. If you aren't using dependency injection, you can remove the constructor and replace the first using statement with (using HttpClient client = new HttpClient())

By the way, the using statement format you saw in my example was the new way of adding using blocks (introduced in C# 8). You can find details here: https://docs.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-8#using-declarations

5ed

You know what I'm going to say. This is the correct way to do this. My 5.

I like it. 5.

Thanks.

Thanks.

And that's the way to solve it. My 5.

It had popped to the top of the queue due to it just being updated.

Are you subscribing to the SelectionChanged event? If you are, just disconnect from the event handler before you associate Data with your ItemsSource. Resubscribe to SelectionChange immediately after DataGrid.ItemsSource = Data;.

When you get null back here, it's indicating that you have no matching elements being returned.
