frmGenerating.ShowModal or ShowDialog?

Re: [Gambas-user] Setting focus to form.

[Rolf-Werner Eilert]

In one of my projects, there are two forms the user switches forth and 
back with "F9". I use ".Main" to show the other form, so

FMain.Main

would it be in your case. But the calling form must still exist for this 
to run, so the splash screen would have to disappear later.

Try and tell if it does what you mean... Maybe Gianluigi's way is better...

Re: [Gambas-user] Setting focus to form.

[Gianluigi]

Hello Rolf,

*FMain.Main* is very good!

If what that Cam Era need is a splash, he might also get with this:

FMain:

Public Sub Form_Open()

  Dim i As Integer

  Form1.Show
  ' Here I make something that I
  ' can communicate through Form1
  For i = 1 To 10
Form1.Comunicate("foo " & CStr(i))
Wait 1
  Next
  Form1.Comunicate("foo " & CStr(i))
  Me.SetFocus
  Form1.Hide

End
Public Sub Form_Close()

  Form1.Close

End


Form1(splash):

Public Sub Comunicate(value As String)

  Label1.Text = "Form 1 " & value

End

Gianluigi

Re: [Gambas-user] Setting focus to form.

[Charlie]

Here is my contribution to this solution. This code shows a 'Splash' screen
while doing a little work then closes the 'Splash' and returns the focus to
FMain.
Hope it helps.
FMainFocus.tar

For object-oriented programming in Gambas a struct can be replaced with
a class. When I started Gambas programming I also made some structs for
the purpose of bringing a couple of variables together to define an
object. But in Gambas the right tool for that is a class.

The class defines an object, you can create an array of a couple of such
objects and you can sort that array.

Re: [Gambas-user] Arrays of Structs

[Gianluigi]

Hello Christof,

I do not use structures and would not recommend using them.
I have only mentioned a file that could satisfy the curiosity of Cam.
In this regard I point to my example DynamicMatrixExample of Software farm.

Re: [Gambas-user] Arrays of Structs

[Tony Morehen]

I may just be responding to a typo but your struct is named MapObjec 
while the code using it refers to MapObject.

Re: [Gambas-user] Arrays of Structs

[nando_f]

I use structs to write binary to a file in struct order.
Nice and easy.
Not so easy with a class.

Your example is possible.  I have done similar.

The STRUCT only defines the structure...it doesn't create the memory allocation.
Static Private WorldMap[100, 100] As MapObject  just defines arrays to point to 
objects.
You need to run code to actually create new objects at each array element.
hint:
Loop  x
 Loop  y
   [x][y] = new MapObject  'the new actually creates a memory allocation for it.
