Using "uses"

edited 5:42PM in FastReport 3.0
Hi,

I try to use the uses command like this 
uses 'c:\source.pas';

procedure Memo80OnAfterData(Sender: TfrxComponent);
begin
  Memo80.Text := ExtractxMonthFromDate(Memo80.Value, True, True);
end;

of course, "source.pas" is in the c:\ target, when compiled i have this message error :
wrote:
identified redeclared:"Memo80OnAfterData
, so i have suspected the "souce.pas" but the memo80 is never declared in this file !

why resolved this error ?

thanks for all.

    Try this convention, where you can manipulate Sender properties:
    procedure Memo2OnBeforePrint(Sender: TfrxComponent);
begin
  TfrxMemoView(Sender).Color := clRed;
  TfrxMemoView(Sender).Text  := ExtractxMonthFromDate( TfrxMemoView(Sender).Value, True, True);
end;

    PS.
    How do you make it that CodeBox doesn't contain too many emply lines?

    Well, I wasn't enough clever to see that it was Memo80OnAfterData that caused an error message from your compiler [img]style_emoticons/<#EMO_DIR#>/sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" /> As at the moment I am NOT Delphi user, so my knowledge of it is very short. Try to add all source of[/img]ExtractxMonthFromDate to the same file (fr3) where you have
    procedure SysMemo27OnAfterData(Sender: TfrxComponent);
var
   res : string;
begin
  SysMemo27.Text :=    SysMemo14.Value + SysMemo15.Value + SysMemo16.Value +
                       SysMemo18.Value + SysMemo19.Value + SysMemo20.Value +
                       SysMemo21.Value + SysMemo22.Value + SysMemo23.Value +
                       SysMemo24.Value + SysMemo25.Value + SysMemo26.Value;
  try
    res := Format('%2.0n', [SysMemo27.Text]); // this does not work
    SysMemo27.Text := res;
  except
    ShowMessage('Erreur de formatage');
  end
end;

    I mean - you do NOT have to compile ExtractxMonthFromDate - you can define it in FR script of your report. If you need to compile your new functions you must do some more work to let FR engine see and accept your user functions like its own (e.g. Format(), VarToStr(), and so on).

    So if you apply your source of new function to FR script and it will work then you will NOT have to compile it and get error msg.

    no no Mick, there is no report with Delphi !!
    the situation is like this : i have 4 reports, each report have its code page, i would like to call the ExtractMonthFromDate function from an external unit witch i define in "source.pas"
    logically i will do this in the header of code page for eatch report
    wrote:
    uses "c:\source.pas"
    but when i do "F9" i have the message error !!

    PS : when i put the function ExtractMonthFromDate in the same page code, the previsualisation is correctly executed.

    So we are at home now [img]style_emoticons/<#EMO_DIR#>/smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> I'm not sure if FR 3 accepts[/img]uses as Delphi compilers do.

    FR 4 comes with so called report inheritance and this functionality seems to be a solution for having pieces of the same code or layout for several reports kept in ONE template.

    If you don't find any solution to have your functions defined once anywhere, then you will have to Copy & Paste this piece of FR script to each report you want to use these functions in [img]style_emoticons/<#EMO_DIR#>/sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" /> But I think that even with these[/img]copied & pasted function your reports will have less lines of script [img]style_emoticons/<#EMO_DIR#>/wink.gif" style="vertical-align:middle" emoid=";)" border="0" alt="wink.gif" /> Mick[/img]

    i think it accepts because he passed succesful the declaration 'uses c:\source.pas'
    for the alternative solution, yes adopte this solution but its not the best method

    i regard other ways...

    Attach an example of your report (fr3 file), or any similar sample, where you use "uses 'c:\source.pas'" and I'll have a look at it.

    My Designer has no components for your Database, but it doesn't matter.
    I see there is NOT Memo80OnAfterData procedure in code page of your report.
    And Memo80 has no events.

    Hi gpi
    conventionaly a pascal unit has this declaration
    interface
    implementation
    in the interface we make the definition of function or procedure and if we want the public variables
    in impmentation we defined the function and procedure declared in the interface part

    so, i have made my all users functions in a "source.pas" and i would like called them in the page code of an FR3 rerport.
    in the "FastReport 3 user manuel " script chapter they said :

    Structure of a script
    Script???s structure depends on the language you use; however there are some
    common elements. They are the script???s title, body, and the main procedure, which will
    be executed when the report runs. Below there are examples of the scripts for all four
    supported languages:
    PascalScript???s structure:
    #language PascalScript // optional
    program MyProgram; // optional
    // the ???uses??? chapter should be located before any other chapter
    uses 'unit1.pas', 'unit2.pas';
    var // the ???variables??? chapter can be placed anywhere
    i, j: Integer;
    const // ???constants??? chapter
    pi = 3.14159;
    procedure p1; // procedures and functions
    var
    i: Integer;
    procedure p2; // nested procedure
    begin
    end;
    begin
    end;
    begin // main procedure.
    end.

    perhaps this doest not worked with FR3 >

    What means that Memo80OnAfterData seems (for FR script processor) to be declared twice.

    I've made some tests both with FR4 (4.10.14) and FR3 (C/S demo 3.15a). And while testing I tried to write as simple as possible script to avoid any complication. My tests have ended with succes - so uses work in general. Maybe it doesn't when script is not so simple.
    Have a look at attached files.

    I have few comments to your examples:

    1. There is no Memo10 on a Page. There is Memo1
    2. OnAfterPrint event may be too late too change contents of TfrxMemoView
    3. There is no replacement instruction to change Memo.Text, like Memo.Text := ReplaceIfBlank(...)
    4. Did you have any errors while running (F9) this report?

    I attach 2 file - your examples with small lifting:
    1. Added box around Memo to be sure that anything was printed
    2. Commented part of simple_source.pas (implementation etc)
    3. Added begin / end. at the end of file.

    Hi

    i think the error was in the interface
    i have do the same with the pascal unit watch has an anterface and implementation section but in the script pascal of FR it does not supported
    i have remove the interface section and the project will word perfectly

    all my thanks to Mick and gpi
