I always joke that I cook because it's something you can "complete", as opposed to software which we write and enhance and fix forever and ever and ever as long as someone is using it! During covid we binge watched like 17 seasons of Top Chef - I learned techniques for foods I will never ever eat, but tricks are tricks - that's when cooking becomes fun.

British cooking has always been extremely good - except since the war up until the 1970s. After the war was over a starving UK had to feed Germany and as a result Britain only stopped rationing in 1954. During the war all artisan production of food was forcibly ended and all food products standardised to feed an almost starving nation. So, that was the end to all unique cheeses and artisan style food products and it affected our diet and pallette.

With the loss of the upper classes (who always ate superbly) and the food that was left for the masses being mainly working class in origin, the food culture in the UK was "eat to live" rather than "live to eat" as it became in the US. We still have that mentality, ie. we like food but it is still mainly considered a fuel so we can do other things. The mindset is that we don't have to eat well, we just have to eat enough. It is now engrained in our culture. You'll see people going on holiday to eat well abroad then coming home and eating the same old crap.

Despite that, British food is now some of the best in the world (see the number of British chefs on TV and the French chefs migrating to the UK) and of course the old country dishes (pies, roasts &c) just won't die, practically every house in the country eats a roast every Sunday.

For the last 20-25 years we have been starting to love our food again and you can now eat really well here. Of course we've always had the best curries in the world! Except for India...

Guys, how did you upload your images? Did you just use the "Insert Image"?

[szlamany]

I first take a screen shot with "Snipping Tool" - this makes tiny jpgs - and use those under GO ADVANCED, MANAGE ATTACHMENTS, UPLOAD - and you can only do 1 image if you want it to be INLINE with the POST like this. I might be wrong about the 1 image after seeing the multi-pic post of those tigers!

[yereverluvinuncleber]

Guys, how did you upload your images? Did you just use the "Insert Image"?

No, go to imgur/upload, load an image. Wait until it renders, then hover the mouse on the image and a "copy link" option will appear, click on the three dots ... choose "get share links".

Choose the option that suits your needs. I typically choose BBCode and paste that text straight into a post.

I never trust the forum's image attachment method as it is untrustworthy.

[Shaggy Hiker]

The other advantage of that last technique is that you have limited uploads on the site, which means that eventually you will either run out of room, or need to remove some.

Why is VB.Net/C#/XAML + VS2019 is better than VB6?

It sure is....but why does VB.NET need XAML?

By logical comparison it should be VB.NET/C#/XAML is better than VB6/XAML (here assuming there is a xaml for vb6).

Sorry for my ignorance.

As far as I know, it does not. WPF needs XAML, but I don't believe XAML can even be used for programs that either A) Don't have a user interface, or 2) Are Windows Forms programs or iii) Are web applications of any sort.

Just like in VB6 where you have different project templates, for example ActiveX EXE, ActiveX DLL etc....Modern versions of Visual Studio also have different templates all backed by .Net. Some of these templates use some flavor of XAML for defining UIs. For example, Xamarin, UWP and WPF projects all use a different flavor of XAML for designing UIs.

As for why VB.Net needs it......Well it doesn't. WinForms and Console projects don't use XAML. I'm guessing that XAML itself is inspired by HTML which allows you design user interfaces declaratively. There are a lot of advantages to designing a user interface declaratively as opposed to doing it by code like you would in WinForms or with Win32 CreateWindow calls.

Interestingly enough, VB6 also uses a declarative syntax behind the scenes in Frm files for defining UIs. The only difference to XAML based projects in .Net is that it's not exposed through the IDE nor did Microsoft provide any tooling for directly using it for manipulating the UI. They probably should have though. Might be a fun little side project to write something like that.

Niya... here's the move... Is pure VB.NET not enough to get into this post? VB6 is a type of winform, although vb6 can work with IIS and activex for web.

It's true kkkkkk. What I lose? Too bad I'm on a diet ....

[Niya]

I would add that you should probably create an account on one of these image sites. While some image hosts do allow you to post images without an account, they are prone to being deleted when the site decides to do some clean up. I don't think they would be so eager to delete images uploaded by registered users. I myself use Imgur.com. Very good site that's very easy to use. I highly recommend.

[Niya]

Niya... here's the move... Is pure VB.NET not enough to get into this post?

When I think of VB6, I think of more than just the language. I think of the IDE, runtime, compiler and any libraries made for VB6 applications. A fair comparison to .Net needs to consider all the development tools in the .Net ecosystem which includes the VB.Net and C# languages, UI mark-up languages like XAML, IDEs like Visual Studio 2019 and libraries like .Net 5 or the .Net Framework. All of these together can cover all the ground VB6 can.

VB6 is a type of winform

Yes. The underlying technology is very different but it is almost exactly the same on the surface.

although vb6 can work with IIS and activex for web.

ActiveX is dead tech. No one should be using that anymore.

[yereverluvinuncleber]

Cheese!

Ug! Well now I have to post this again:

[Niya]

I find British humor extremely appealing for some reason. Yes Minister was one of the funniest shows I have ever seen in my life to this day.

[Niya]

One reason it is better.... https://devblogs.microsoft.com/visua...now-available/ a new version is available

Finally doing it. I just did a system reset because I needed to clean out a bunch of crap installed on my PC over the years. Decided to give to VS-2022 a try instead of going back to VS-2019. Installing it right now...

[Niya]

While I have no real interest anymore in reviving this discussion, this one aroused my interest in comparing VB6 and .Net.

Here is the problem. Guy wants to shuffle an array into a random order:-

I search since 2 hours without success (found topics that not matching with what I want to do).

I have a function that list files from folder and its subfolder and add each of them itoo an array.

I need to shuffle items before list (shuffled) 30 items max.

Limit to 30 will probably not a problem but shuffle items before that is a problem for me


Is there something equivcalent to php shuffle() function ?

$my_array = array("red","green","blue","yellow","purple");
shuffle($my_array);
print_r($my_array);

Thanks
Couin

What struck me was how verbose a lot of the suggestions are. I'll just post one example from the thread:-

Option Explicit

Private Declare Function GetMem4 Lib "msvbvm60" (ByRef Source As Any, ByRef Dest As Any) As Long ' Always ignore the returned value, it's useless.


Private Sub Form_Load()
    Dim sa() As String

    sa = Split("red|green|blue|yellow|purple", "|")

    StrArrShuffle sa

    Debug.Print Join(sa, "|")

    StrArrShuffle sa

    Debug.Print Join(sa, "|")

End Sub

Public Sub StrArrShuffle(sa() As String)
    Dim i As Long, j As Long, k As Long
    Randomize
    For i = LBound(sa) To UBound(sa)
        j = Int((UBound(sa) + 1) * Rnd)
        GetMem4 ByVal VarPtr(sa(i)), k
        GetMem4 ByVal VarPtr(sa(j)), ByVal VarPtr(sa(i))
        GetMem4 k, ByVal VarPtr(sa(j))
    Next
End Sub

In comparison, this is how it could be done in VB.Net:-

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim r As New Random
        Dim s = {"red", "green", "blue", "yellow", "purple"}

        Debug.WriteLine(String.Join("|", s))

        s = (From num In Enumerable.Range(0, s.Length)
             Order By r.Next
             Select s(num)).ToArray


        Debug.WriteLine(String.Join("|", s))
    End Sub

I'm not looking to start up all this drama again but I'd actually be curious to see if this could be done as concisely in VB6.

[Shaggy Hiker]

It can't, but it can certainly be written faster. LINQ is very concise, but it is not very efficient. That's a trade off that often doesn't matter. Still a trade off, though.

...I'd actually be curious to see if this could be done as concisely in VB6.

Private Sub Form_Load()
  Dim a: Set a = New_c.ArrayList(vbString, "A", "B", "C", "D", "E")
  
  Debug.Print a.Join("|")
  
  Dim b: Set b = New_c.ArrayList(vbString)
  Dim v: For Each v In a: b.Add v, Rnd * b.Count: Next
  
  Debug.Print b.Join("|")
End Sub

Well, I don't think anyone should be using LINQ for performance. It should be used for it's convenience in places where high performance doesn't matter. However it's very easy to get seduced by it's elegance and flexibility which can lead one to use it everywhere, including places where it shouldn't be used. I used to be guilty of this when I started using it.

Private Sub Form_Load()
  Dim a: Set a = New_c.ArrayList(vbString, "A", "B", "C", "D", "E")
  
  Debug.Print a.Join("|")
  
  Dim b: Set b = New_c.ArrayList(vbString)
  Dim v: For Each v In a: b.Add v, Rnd * b.Count: Next
  
  Debug.Print b.Join("|")
End Sub

Ah ok. That's pretty concise. I really wish I'd known about RC5/6 back when I was in VB6. It would have been a whole lot less painful solving simple problems like this.

I find the behavior of your ArrayList interesting though. It seems you can add elements to it at any index without knowing or setting the size of the ArrayList which quite handy but also quite odd. I can't find any precedent for this behavior. Did you come up with that on your own or is there some "prior art" upon which that behavior is based? Perhaps some collection class in a JavaScript or Python library somewhere?

[Schmidt]

Not exactly "without knowing the size",
because the second param of the Add-method does respect "the current ListCount".

Yes, the VB6/VBA-Collection has similar support in its Add-method -
but prior to the introduction of the VB-Collection-object into the VB-runtime,
such an optional second param was present also on a "Visual-Control" (VB.ListBox):

The following code produces the same "shuffled output-sequence" of A,E,D,C,B as the RC.cArrayList-example:

Private Sub Form_Load()
  Dim lb As VB.ListBox, v
  Set lb= Controls.Add("VB.ListBox", "lb")
      lb.Visible = True: lb.Height = ScaleHeight
 
  For Each v In Array("A", "B", "C", "D", "E")
    lb.AddItem v, Rnd * lb.ListCount
  Next
End Sub

In comparison, this is how it could be done in VB.Net: <<big snip>>

Btw, the VB6 sample code does *not* even copy strings because it swaps pointers which is an optimization of the straight-forward VB6 solution.

I mean you could have tried to show some optimized attempt and wrap it in a reusable function (the VB6 code shuffles twice BTW). Doubt any optimization would have been shorter in VB.Net

How do you swap strings without copying their content? Is it possible in .Net at all? This next episode of the saga might turn into a *big* counter-example IMO :-))
