Re: How to convert unix time to datetime (C#) ?

I don't see how that will work since you are adding a double value to an integer one, which means you lose all the precision. You would first need to convert the time portion of the Unix value into an integer number of seonds. Try some of these links[^].

Use the best guess

Not tested, but I believe the following should do the trick for you...

/// <summary>
/// Calculate the starting time for Unix epoch (see http://en.wikipedia.org/wiki/Unix_time).
/// </summary>
public const long unixEpoch = new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc).Ticks;

static DateTime toDateTimeUtc(
    long unixTime)
{
    return new DateTime(unixTime + unixEpoch, DateTimeKind.Utc);
}

static long toUnixTime(
    DateTime dateTime)
{
    return dateTime.ToUniversalTime().Ticks - unixEpoch;
}

What kind of video recognition software exists?

I'm aware of facial recognition software, but that is too specific. Are there any other types of camera footage recognition software out there?

I don't even know what's happening.

What do you mean by "camera footage recognition"?? The term makes no sense on its own.

A video is a bunch of frames, so, theoretically, you can apply facial recognition to each of these frames. However, there may be other complications like blur; so, you'll have to apply blur-removal algorithms; and these may not work well in all situations.

You want it less specific? Like "gender" or what?

Given that it needs training to recognize "things", I'd guess that it could learn to discriminate between animals.

Remplir une datagridview à l'aide d'une autre

Bonjour,
J'ai deux datadridview ( datagridview1 vide dans Form1 et datagridview2 affichant quelques éléments de la DB dans Form2).
Un bouton "ajouter" sur Form1 et un bouton "selectionner" sur Form2.

Mon désire est que si je clique sur un bouton ajouter dans Form1, j'ouvre Form2. Lorsque je selectionne une ligne de datagridview2 et que je clique sur le bouton "selectionner " cette ligne s'affichera dans la datagridview1 de Form1 et disparaitra dans datagridview2 (Form2).

Même si je clique encore sur "Ajouter" j'arrive à faire la même chose.

Merci pour votre aide

Fill a datagridview using another

Sorry,
I have two datadridview (an empty dataGridView1 in Form1 and datagridview2 with data in Form2 ).
I have also "add" button on Form1 and "select" button on Form2 .

My wish is that if I click on "add" button in Form1 , I open Form2. When I select a line of my datagridview2 and when I click on the "select" button this line will appear in the dataGridView1 Form1 and disappear in datagridview2 (Form2) button.

Although I still click on "Add" I can do the same thing.
please help me

OK, so Form2 would be shown with ShowDialog. When the record is selected on it, Form2 code sets a public property that Form1 will read to pickup the record that was selected.

You can do this. Not the easiest. Best is is look at the message that is sent by the page to request the data. Then you will get back the html for the web page. Will have to find some take in the page that you can search on, and then basically interpret the HTML to figure out what the response was.
