Ini configuration file

Here is a complete introduction to TIniFile objects: Using Delphi built-in functions to read and write INI files

After reading the above introduction, we started to read and write the INI file.

First, prepare an INI file in the same directory as the program. The file content is as follows:

[System]

Server = 127.0.0.1

DataBaseName = pubs

UserName = sa

Password =

Then, draw a form, add four Edit controls and a Button control, and use the default name.

Finally, write the code:

Implementation

Uses IniFiles;

Var

IFile: TiniFile;

{$ R *. dfm}

Procedure TForm1.FormCreate (Sender: TObject); {value of INI file read when the form is loaded}

Begin

IFile: = TIniFile. Create (ExtractFilePath (Application. ExeName) + 'data. ini ');

Try

Edit1.Text: = iFile. ReadString ('system', 'server ','');

Edit2.Text: = iFile. ReadString ('system', 'databasename ','');

Edit3.Text: = iFile. ReadString ('system', 'username ','');

Edit4.Text: = iFile. ReadString ('system', 'Password ','');

Finally

IFile. Free;

End;

End;

Procedure TForm1.Button1Click (Sender: TObject); {the value of the INI file written when you click the button}

Begin

IFile: = TIniFile. Create (ExtractFilePath (Application. ExeName) + 'data/data. ini ');

Try

IFile. WriteString ('system', 'server', Edit1.Text );

IFile. WriteString ('system', 'databasename ', Edit2.Text );

IFile. WriteString ('system', 'username', Edit3.Text );

IFile. WriteString ('system', 'Password', Edit4.Text );

Finally

IFile. Free;

End;

End;

Ini. Free;

End;

 

Var
Iserver, idatabasename, iUserName, iPassword: string;
IPort, itime: string;
Begin
IFile: = TIniFile. Create (ExtractFilePath (Application. ExeName) + 'pdaservice. ini ');

Try

Iserver: = iFile. ReadString ('data', 'server ','');

Idatabasename: = iFile. ReadString ('data', 'databasename ','');

IUserName: = iFile. ReadString ('data', 'username ','');

IPassword: = iFile. ReadString ('data', 'Password ','');

IPort: = iFile. ReadString ('Port', 'serviceport ','');

Itime: = iFile. ReadString ('time', 'interval ','');
