You could also replace cos(x)/sin(x) with either cot(x) or 1/tan(x), but I dont know if that will be better.

Kenneth Haugland 23-May-23 11:15am View

I find it easiest to create an attached property/behavior to the listview, and use Linq to do the filtering.

Kenneth Haugland 13-May-23 9:45am View

I think you have some logical flaws in your code. Why not check if the num1 == num2 and num2 == num3 instead?

Kenneth Haugland 11-May-23 6:38am View

Homework?

Dang... I saw it just now as well...

Where do you read the chart data from? Excel?
Do you type them in manually or read them from a file?
The question you have asked I cannot answer, so please improve it.

Kenneth Haugland 22-Feb-23 5:48am View

Perhaps you should call InvalidateVisual or something similar? And have you debugged the code?

Kenneth Haugland 22-Feb-23 1:12am View

I gonna need a LOT of coffee to even attempt to look at this :)

Kenneth Haugland 17-Feb-23 3:06am View

Normally you would just do the checks in a background thread and post the result to the main thread were the UI usually runs. But are you sure you mean C, and not C++ or C#?

Kenneth Haugland 9-Feb-23 10:22am View

First open C++ in appropriate IDE, then do some coding. And Googling

Kenneth Haugland 26-Jun-21 9:32am View

Ill take that back, you just need some new Task items, and start them in succession

Kenneth Haugland 20-Jun-21 18:50pm View

Did you implement INotifyPropertyChanged on the properties in your ViewModel? How did you link up your ViewModel to the Window?

Kenneth Haugland 25-May-21 3:40am View

Can also use BindableBase from Prism if you use that

Kenneth Haugland 20-Apr-21 4:55am View

It works but you have to set it up correctly:
public MainWindow()
{
InitializeComponent();

ClassItems Myinput = new ClassItems();
ChildWindow dlg = new ChildWindow(ref Myinput);
dlg.Show();
}
With class:
public class ClassItems
{
public int MyProperty { get; set; } = 50;
}
With the child window:
public partial class ChildWindow : Window
{
public ChildWindow(ref ClassItems test)
{
InitializeComponent();
test.MyProperty += 55;
}
}

Kenneth Haugland 14-Apr-21 6:57am View

Then I would do something like: public uroven(MyClass ref ClassImplementation)
{
InitializeComponent();

}

its either out of ref, cant remember. The point is that you can pass this class in from the constructor as a referance to a variable in your window that "owns" or rather constructs this.

Kenneth Haugland 21-Mar-21 17:07pm View

Where did you actually set the instance to the DataContext. It's not entirely clear to me. Normally I would set:
<window.datacontext>
<local:intestazione>

It might be a rather recent addition to Visual Studio, I have not noticed it before either. But having to use a deserializer forced me to o some googling and then I found this.

Kenneth Haugland 20-Feb-21 11:04am View

Where is your interface code? The ISearchModel?

Kenneth Haugland 20-Feb-21 7:31am View

Tothe op: Copy your Json string into a Visual studio class using: Edit-> Paste Special -> As Json class. That generates the class for you.

Kenneth Haugland 20-Feb-21 6:14am View

Can we see you attempt? Or is that top secret stuff?

Yes. Or No. Hard to tell. You must explain further.

What is this: LATE.SelectedValue? Can I see the actual value of this? and you should remove the "" as it should be a value, and you should call ToString() on it and make sure that it is a time format

He asks if you print out row.Cells["Month"].Value what do you see? In general, it is better to say something like ToLower on both and use Contains in order to do filtering.

What did you do to show the picture then?

Kenneth Haugland 8-Dec-17 3:56am View

Got it, if you add 'salt' hashed password is stronger if you don't, it's weaker. Lesson: You have to do it right :-)

Kenneth Haugland 8-Dec-17 3:15am View

I thought like this:
Login if GetHash(WrittenPassword)==StoredPasswordHash

has many => one relation

If I used the original password:
Login if WrittenPassword == StoredPassword

has:
one => one relation

Am I missing something here?

Kenneth Haugland 8-Dec-17 2:55am View

I read that as if you store the password with hashes you actually make it weaker.

Kenneth Haugland 7-Dec-17 5:12am View

'that's why they are used for password storage instead of encryption functions.' Eh, so there is more than 1 correct passsword?

I really dont think you understand this:
"This Professional .NET Excel component is a standalone Excel .NET managed assembly and does not depend on Microsoft Office Excel. Spire.XLS for .NET offers support both for the old Excel 97-2003 format (.xls) and for the new Excel 2007,Excel 2010, Excel 2013 and Excel 2016 (.xlsx, .xlsb, .xlsm), along with Open Office(.ods) format. It features fast and reliably compared to developing your own spreadsheet manipulation solution or using Microsoft Automation." Meaning it creates an Excel file, and to be able to use Excel.Interop you need to have Excel installed on your computer. If you are wondering about how to do stuff in Excel, just use record macro and look at the excel code.

"When creating a phase of the implementing dll's in the containing dll, the containing dll has to reference the implementing dll's, resulting in a circular reference." Then move the phase out of the interface dll.

Kenneth Haugland 4-Dec-17 5:01am View

xls files are xls files, so what is your problem then? Why not simply use IO file.copy?

Kenneth Haugland 1-Dec-17 6:55am View

WPF WinForms, or what?

Kenneth Haugland 29-Nov-17 8:33am View

Use an IValueConverter and bind this to the expander and a search criteria?

Add System.Drawing as a referance and type:
oSheet.get_Range("A2").Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

That worked for me.

In general, an FFT will give you all frequency data within a given time span and not one frequency each second.

Are you using WPF, in that case just put in a RotateTransform on the control, and you are done.

Split your list up in smaller lists, or create your own that does this for you.

Kenneth Haugland 9-Aug-16 6:37am View

Depends on what you want, but normally I would suggest you draw the controls on a Canvas, and just move them by changing the Canvas.Left Canvas.Top on the control you want to move. But, you have to provide more information on what you want to do here.

Kenneth Haugland 4-Aug-16 15:52pm View

Well, it didn't work right away. I had to build it the second time then all issues were gone. It doesn't per say ruin the MVVM pattern, as the update binding is generic. It doesn't know what the TextBox is bounded to. But I agree, it should not be necessary. BTW: What version of VS are you using?

Your problem is that the binding expression is null;

What a weird question. What do you consider a fair value of a car? Surely it would depend.

The question you should ask is how large the probability should be for you to make a profit? Should you accept losing money 5% of the time? This way your fair question becomes a mathematical question.

That is too big a question to answer, you are not stuck at a point trying to do it, you want the whole book about it. I cant do that, so my answer is the best you'll get at this point.

Don't have the article, but intensity in audio is defined as => 0.5 Re{p v*} where v* is the complex conjugate of the velocity and p is the pressure. This is called the active part of the intensity, you could take Im{} to get the reactive part as well but we normally don't care about that. As you see, in order to get the actual intensity, you need to get the calibrated values, not jus the wave file (or whatever format you have on the audio file).

WPF is basically a DirectX wrapper, so If you want to create games, you should go directly for DirectX and C++, as it's bound to give you better performance. WPF does a lot of things well, but running a modern day 3D game is not one of them.

You haven't, I think that it is declared as a local variable inside the for loop, not everywhere. That is the why It use to be at least.

I'm tempted to tell him to switch to vb instead:
For i as integer = 0 to 100 step 1
No-one can mess that up :)

Linq would be the easiest way I could think of

Kenneth Haugland 26-Sep-15 1:51am View

This does not seem right. Are you sure that you haven't switched places with i++ and i<100 ?

Kenneth Haugland 24-Sep-15 0:32am View

This is WinForms so I don't really know the answer, but It sounds to me as you are doing something unnecessary difficult here?

Kenneth Haugland 24-Sep-15 0:28am View

The control have a selection changed event, why don't you use that?

Kenneth Haugland 24-Sep-15 0:26am View

You should consider getting some books, perhaps from the local library?

IF you are asking this question, you are probably not using WPF as you should.

You should include the necessary code in your answer and generally not post links to third party sites without the relevant code in your answer. If the link fails the answer isnt real anymore

You might consider using a PixelShader here, it will ensure that all frames are treated.

Kenneth Haugland 22-Sep-15 9:52am View

Ehm, use bindings to show data and perhaps a RelayCommand to add new data?

This Q&A section is for specific questions only. Not, can you write a book to me type of questions. Do your research and try it out, and when you are stuck come back with a real question.

Kenneth Haugland 21-Sep-15 5:22am View

Excel arrays start at 1 and not 0, so that's why you get the error. So you woul dhave to change the for loop from j=0 to j=1.

Kenneth Haugland 21-Sep-15 3:56am View

Ah that would explain it, but there aren't really any strict rules here, we kind of just self police this Q&A section, for better or worse.

Customizing layout and controls in WinForm is a nightmare. WPF makes this process much more manageable. If you know what you are doing it shouldn't take more than 15 minutes or so to get it working in WPF, in WinForms I wouldn't even know where to start.

Ditch WinForms and so it in WPF instead, its much easier.

One makes a copy and the other don't, and functions as a pointer instead. Not a Java expert, but normally it has to do with the initialization of variables.

Just do a search for ray tracing, I have seen examples here on this site of that.

Kenneth Haugland 18-Sep-15 16:22pm View

No, the WPF 3D engine uses matrices not ray tracing. So it is what you want...

Kenneth Haugland 17-Sep-15 20:24pm View

Get a ImageBrush of lines and set it as the background or fill, and use RotateTransform on it. Thats what Id do in XAML C#/VB anyway.

And use opacity to define how clear it should be.

Kenneth Haugland 17-Sep-15 20:06pm View

Its what you'll need to calculate. IIRC this is usually done using determinant of a matrix.

I would think all the points need to be recalculated in any zoom, its just that you don't see those calculations.

Kenneth Haugland 13-Sep-15 5:45am View

I assume this is an WinForm app?

Kenneth Haugland 8-Sep-15 9:06am View

Yeah, you can do it from the blur instance directly, but that is often not the way you want to do it, as it makes it difficult to do multiple animation at the same time. I think the namescope is only needed to pinpoint the object that you want to do animation on.

From the VS developers:

Kenneth Haugland 8-Sep-15 8:24am View

>It is for BlurBitmapEffect, not for BlurEffect.
That is correct, but the only thing that is different is that the BitmapEffects are done in the CPU while the new Effects are done in the GPU. Everything else is pretty much as it should be now.

I believe you need the namescope in order to get the animations working.

Kenneth Haugland 8-Sep-15 8:19am View

IT works if you register the namescope. I did something simular a while back:

And you definatly need a unique name to mtarget a storyboard to a control:

You should know that animations work because of binding, and binding only works with dependency properties, so you are simply wrong here.

Kenneth Haugland 8-Sep-15 7:33am View

Not true:
http://bursjootech.blogspot.de/2008/06/grayscale-effect-pixel-shader-effect-in.html

All PixelSHader Effects deriving from the ShaderEffects class are dependencyproperties

Kenneth Haugland 8-Sep-15 7:15am View

I think you are asking the wrong questions here, as any dependency property that is of double format is valid for animation. You would simply have to check the animation type with the property that you want to animate, and perhaps also its to and/or from values are withing the boundaries of the property you want to animate.

Kenneth Haugland 8-Sep-15 6:23am View

I guess you can do this:

Usually the power spectrum is 20*log10(abs(FFT)), you seem to favor the natural logarithm? In any cast that is just for viewing the spectrum.

I don't know what you mean by inverse the signal, if it is back to its original you need to perform an ifft of the fft.

Kenneth Haugland 26-Jul-15 7:42am View

You first need to have a FFT implemented, then the rest is just visuals from that information.

Yes, you are right. The reason for saying that Archimedes knew it is this:

Kenneth Haugland 30-Jun-15 10:07am View

I think this formula has been known since Archimedes, as it is just a Cauchy Integration (which ironically enough was known to Archimedes).

Oh, the formula does not work if the Polygon is self intersecting.

Cant you just use a dictionary with phonetic sounds, and compare the sounds?

Should be careful with this, ',' and '.' are both valid as a decimal place depending on the culture on the pc.
