How to say data to a file

[Guest_imported]

How can I save to a file, say myfile.ini, some CheckBox settings from my application so when I re-open my application these CheckBox settings are restored.

Here is one possible way. You will need to include the

<iostream.h>

at the beginning of your program. Then open a file.

ofstream MyFile; // stream set up
MyFile.open("MyFile.ini", ios::out);

if (!MyFile)
{
     Application->MessageBox("Cannot open INI file.", "File Error", MB_OK);
     return;
}

This will open a file named "MyFile.ini" for output and will also check to make certain the file was properly created. Depending on which version of libraries and compilers you are using, you may have to include the standard namespace.

After opening the file you can then send it some information.

if (RadioButton1->Checked == true)
    MyFile << &quot;RadioButton1 = true&quot; << endl;
else
    MyFile << &quot;RadioButton1 = false&quot; << endl;

Somewhere you need to do the opposite. Open the file for input and see if "RadioButton1 = true" and set

RadionButton1->Checked = true

.

Does this help? James P. Cottingham

hey, if its an .ini file, its much simpler than that.

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

#include <vcl.h>
#include <IniFiles.hpp> // <-be sure to include this!!
#pragma hdrstop

#include &quot;Unit1.h&quot;
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource &quot;*.dfm&quot;
TForm1 *Form1;
TIniFile *ini; //initialize .ini file
//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{

ini = new TIniFile (ChangeFileExt( &quot;TestCheck&quot;, &quot;.INI&quot; ) );

if (ini->ReadBool (&quot;CheckBox1&quot;, &quot;Checked&quot;, false)==false)
CheckBox1->Checked=false;
else
CheckBox1->Checked=true;


}
//---------------------------------------------------------------------------
void __fastcall TForm1::CheckBox1Click(TObject *Sender)
{
if (CheckBox1->Checked==true)
{
ini->WriteBool (&quot;CheckBox1&quot;, &quot;checked&quot;, true);
}
else
{
ini->WriteBool (&quot;CheckBox1&quot;, &quot;checked&quot;, false);
}

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


you can also read strings, write strings, experiment, just type in ini-> and c what pops up. Cyprus
