 |
|
I was using this article on using .ini files(http://functionx.com/bcb/howto/inifile.htm). But in there examples it doesn't do much. It only gives examples on how to read specific values :
| Code: |
void __fastcall TForm1::FormCreate(TObject *Sender)
{
TIniFile *StartUp = new TIniFile("IValues.ini");
// The FormPos section
Left = StartUp->ReadInteger("FormPos", "Left", 250);
Top = StartUp->ReadInteger("FormPos", "Top", 200);
// The controls values section
edtPreview->Text = StartUp->ReadString("CtlValues", "txtPreview", "Euzhan Palcy");
cboFonts->Text = StartUp->ReadString("CtlValues", "FontSelected", "Times New Roman");
cboFontSizes->Text = StartUp->ReadString("CtlValues", "FontSize", "24");
scrRed->Position = StartUp->ReadInteger("CtlValues", "RedPos", 0);
scrGreen->Position = StartUp->ReadInteger("CtlValues", "GreenPos", 0);
scrBlue->Position = StartUp->ReadInteger("CtlValues", "BluePos", 0);
delete StartUp;

As you can see it is reading specific values out of the .ini file, I want to know just how to read values, not a specific value like 250. I also am confused if ReadInteger/ReadString is for writing, I'm pretty sure its for reading as the name states, but I'm not sure because of this quote from the article.
| C++ Builder Tutorial - INI Files wrote: |
To create and manage the sections that make up an INI file, the TIniFile provides a series of methods such as ReadSection() and ReadSections(). To create and manage the strings of an INI file, you use the methods of the parent class TCustomIniFile. When creating the strings, you use Read() methods.
Here is an example:
//---------------------------------------------------------------------------
void __fastcall TForm1::FormCreate(TObject *Sender)
{
TIniFile *StartUp = new TIniFile("IValues.ini");
Left = StartUp->ReadInteger("FormPos", "Left", 250);
Top = StartUp->ReadInteger("FormPos", "Top", 200);
delete StartUp;
}
//---------------------------------------------------------------------------
To retrieve the values of the strings, you use Write() methods. Here is an example:
//---------------------------------------------------------------------------
void __fastcall TForm1::FormClose(TObject *Sender, TCloseAction &Action)
{
TIniFile *StartUp = new TIniFile("IValues.ini");
StartUp->WriteInteger("FormPos", "Left", Left);
StartUp->WriteInteger("FormPos", "Top", Top);
delete StartUp;
}
//---------------------------------------------------------------------------

As you can see it is saying to retrieve values with Write() and creating the stuff with Read(), but I mean that would be stupid names, so I would just like some clarifications and once again if anyone has some specific .ini file tutorials for C++ it would be nice.

I have no idea what you are *exactly* looking for, but I've been using readprivateprofilestring and writeprivateprofilestring for a long time now.

As for the code you posted, my guess is that it's not reading the specific value but instead...
| Code: | | Left = StartUp->ReadInteger("FormPos", "Left", 250); |
That would be looking at the INI for '[FormPos]' and the key would bey 'Left' the default value if it was not found would be 250, but it would use the value that Left equals if one was one.
