TEdit out of scope

keeping it short: this TEdit is obviously out of scope, how do i gain access to the elements in the TEdit??

/*
[C++ Error] Unit2.cpp(25): E2247 '_fastcall TControl::GetText()' is not accessible
[C++ Warning] Unit2.cpp(32): W8004 'testing' is assigned a value that is never used


*/
void __fastcall TEnterHandleForm::EnterHandleButtonClick(TObject *Sender)
{
   char Handle[100];
   Handle[0] = '\0';
   TEdit* testing;
   testing = EditHandle;
   Handle = testing->GetText();
}

you must do one of the following

strcpy(buffer, EditBoxForPersonsHandle->Text.c_str());

of declare buffer as AnsiString and then do the following:

Buffer = EditBoxForPersonsHandle->Text;

declare your TEdit variable in your class, which is in the .h or .hpp file. At the minute your variable is only accessilbe to this function

your header file looks something like:


class YourProject : TForm
{
     public:
       // functions


     private:
       // declare your TEdit control/variable here

You could use testing->Text; and because you are declaring as char[] you can use testing->Text.c_str();
I assume you have 2 forms with TEdits and you want to get the text from an editbox in one form to an editbox in another or something like...
Anyway:
The TEdit you want to read from in a form declared as "protected". So using Formx->TheEditBoxIWantToRead->Textyou can get the text inside the editbox. The Formx header HAS TO be included in the unit you will use the read function eigther is another form or a class....
If it is a class then declare a TEdit in the private area and a function to set in the public area like:
private:
  TEdit  *ClassEdit;

 void SetTEditBox(TEdit *FormEdit)
{
    ClassEdit = new TEdit(this);
    ClassEdit = FormEdit;
}
Don't forget to destroy the ClassEdit to your class destructor...
Assign the formedit from your main unit AFTER you create the instance of the class by calling the public function.

sorry if i am unclear... i don't have much experience in C++, maybe 8 months, really don't know much about classes.
what i am trying to do.. .is get the text from a EditBox when i push a button(lets call it button1) and store it in a variable.

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

#include <vcl.h>
#pragma hdrstop

#include "Unit1.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TEnterHandleForm *EnterHandleForm;
//---------------------------------------------------------------------------
__fastcall TEnterHandleForm::TEnterHandleForm(TComponent* Owner)
        : TForm(Owner)
{
}
//---------------------------------------------------------------------------
void __fastcall TEnterHandleForm::Button1Click(TObject *Sender)
{
 // below is the code, the error is now telling me "Lvalue required"
/*   not sure if it matters, but when i click on the "EditBox" it takes me to the function for the edit box (so i can code it)
but if there's no code (hence i didn't code anything in the edit box) the function just dissapears.
*/
  char buffer[40];
  buffer[0] = '\0';
  buffer = EditBoxForPersonsHandle->Text.c_str();
