Arrays

rbuser

Hi
Is it posible to use arrays in rap code. I need an array that allows me
access to a specific position to read or manipulate its value
I'm using RB 14.08

Thanks

Hi Ignacio,

Arrays are not supported in RAP. If you need to keep a list of values,
I suggest using a TStringList object to do so in RAP.

Thanks Nico
Could you please give me an example about accessing and modifying a
specific value in the x position?

Hi Ignacio,

I'm sorry but I'm unclear about what you are trying to accomplish. Are
you trying to manipulate the horizontal location of a report component
in RAP code? If so, this should be fairly simple to do before the
component (or band) is printed.

Hi
I asked an example of simulating arrays manipulation with TStringList
because I couldn't use many properties of the TStringList component as
in delphi. For example delimiter property, delimitedtext property, and
others. It seems that not all TStringList properties and methods are
able in rap code. I think I solved it using the available methods
Thank for asking and answering

Hi.

For check what properties (methods) available in RAP I used next code:

uses
ppRTTI,
raObjectRTTI;


procedure TTestForm.StringListRTTIPropsToFile;
begin
ClassRTTIPropsToFile(TStringList, 'c:\Test\StringListRTTI.txt');
end;

procedure TTestForm.ClassRTTIPropsToFile(AClass: TClass; const AFileName:
string;
Encoding: TEncoding = nil);
var
PropList: TraPropList;
begin
PropList := TraPropList.Create;
try
TraTStringListRTTI.GetPropList(TStringList, PropList);

PropList.SaveToFile(AFileName);


// you can put memo on form and used next code
// Memo1.Text := PropList.Text;
finally
PropList.Free;
end;
end;

Thanks!
I solved the array capability using basics methods of TStringList and
those methods that RAP code doesn't accept or recognize as delimeter or
delimeted text, I did it with traversing through the list with a FOR
sentence and concatenating strings
