How to use Memo1 in a function

[Espresso]

Hi everyone!


I'm trying to use Memo1 (as an text output on a Form) in a function. But it won't work. I get this Error:[C++ Error] Unit1.cpp(43): E2451 Undefined symbol 'Memo1'

Obviously I have to define "Memo1" in this function but I don't know how.

This is my code:

//---------------------------------------------------------------------------

#include <vcl.h>
#pragma hdrstop
#include <stdio.h>
#include <stdlib.h>
#include <iostream>


#include "Unit1.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;
//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
        : TForm(Owner)
{
}

void print_with_memo();

//---------------------------------------------------------------------------
void __fastcall TForm1::Button1Click(TObject *Sender)
{
        char testText[15];

        sprintf(testText,"Hello World");
        Memo1->Lines->Add(testText);      // Works correct!

        print_with_memo();

}
//---------------------------------------------------------------------------

void print_with_memo(textText)
{
        char testText[15];
        //TForm1::Memo1;
        //TMemo *Memo1;

        sprintf(testText,"Hi There");
        Memo1->Lines->Add(testText);     // Error: Undefined symbol Memo1
}

//------------------------------------------------------------------------

Does someone know how to define/declare this Memo1 when it's used in a function???

Button1Click is a TForm1 member function, print_with_memo isn't.
Is Memo1 a TForm1 member?

[Espresso]

yes, that's why it doesn't work in the function.

But maybe I can define/declare Memo1 as a TForm1 member in this function.

What do you think?

[Espresso]

somebody an answer?

Make print_with_memo() a member of TForm1.

Yes! thank you, it's working!
