Progress for very small values of "progress"?

More examples of special, arbitrary rules for objects vs. every other data type 
in 4D.

This is not progress.

Hello,

At the end of the backup the database method ‘On backup Shutdown’ is fired.
This method receive a error code as first parameter.
You may have more detail thanks to GET BACKUP INFORMATION command.

Unless you are using the OBJ Module component, this syntax would not allow dot 
notation. Now that R4 beta includes dot notation natively, I prefer to use the 
native code and so I ask the question.

Re: OB Copy, New Object, or $1

[Douglas von Roeder via 4D_Tech]

John:

I would use Cannon Smith's "OBJ Module". The component is 4D code that
allows supports dotted notation.


For many years, I passed an Object Tools Object at $1 so my code looks like

C_Longint($h_;$1)
$h_:=$1

When I use C_Object, it's

C_Object($O_;$1)
$O_:=$1

OB Copy, New Object, or $1

[John Baughman via 4D_Tech]

In order to use dot notation a c_object must have been initialized. So when 
passing a c_object as a parameter to a method you cannot use dot notation on 
the object as you might normally do with any other kind of parameter. This will 
not work...

C_Object($myCoolObject;$1)
$myCoolObject:=$1
If($myCoolObject.action=“Startup”)  // this will generate a syntax 
error.
End If

So we have several options…
C_Object($1)
If($1=“Startup”)
End If
Or
c_Object($myCoolObject;$1)
New object(myCoolObject)
$myCoolObject:=$1
If($myCoolObject.action=“Startup”)  
End If
Or
C_Object($myCoolObject;$1)
$myCoolObject:=OB Copy($1)
If($myCoolObject.action=“Startup”)
End If

Is any one of these options better than the other? I am guessing not. Since I 
like to always have readable vars, $1 means nothing, I have opted to use OB 
Copy as it is the simplest form and closest to myCoolObject:=$1.

Any other way to do this?

John

RE: Widget questions

[Piotr Chabot Stadhouders via 4D_Tech]

Hi Timothy,

Thanks for your answer!

We are 4D partner but I don't know if I can, and if so how I can vote for your 
bug.

Do you know how I can do that?

Thanks,

Piotr
