运行bat文件
用shellexecute调用bat文件名

读取ini文件的内容
The ini file format is still popular, many configuration files (such as the DSK Desktop settings file) are in this format. This format is especially useful in cross-platform applications, where you can抰 always count on a system Registry for storing configuration information. BaseCLX provides two classes, TIniFile and TMemIniFile, to make reading and writing ini files very easy.
On Linux, TMemIniFile and TIniFile are identical. On Windows, TIniFile works directly with the ini file on disk while TMemIniFile buffers all changes in memory and does not write them to disk until you call the UpdateFile method.

When you instantiate the TIniFile or TMemIniFile object, you pass the name of the ini file as a parameter to the constructor. If the file does not exist, it is automatically created. You are then free to read values using the various read methods, such as ReadString, ReadDate, ReadInteger, or ReadBool. Alternatively, if you want to read an entire section of the ini file, you can use the ReadSection method. Similarly, you can write values using methods such as WriteBool, WriteInteger, WriteDate, or WriteString.

Following is an example of reading configuration information from an ini file in a form's constructor and writing values in the OnClose event handler.

__fastcall TForm1::TForm1(TComponent *Owner) : TForm(Owner)

{
TIniFile *ini;
ini = new TIniFile( ChangeFileExt( Application->ExeName, ".INI" ) );
Top = ini->ReadInteger( "Form", "Top", 100 );
Left = ini->ReadInteger( "Form", "Left", 100 );
Caption = ini->ReadString( "Form", "Caption",
"Default Caption" );
ini->ReadBool( "Form", "InitMax", false ) ?
WindowState = wsMaximized :
WindowState = wsNormal;
delete ini;
}
void __fastcall TForm1::FormClose(TObject *Sender, TCloseAction &Action)

{
TIniFile *ini;
ini = new TIniFile(ChangeFileExt( Application->ExeName, ".INI" ) );
ini->WriteInteger( "Form", "Top", Top );
ini->WriteInteger( "Form", "Left", Left );
ini->WriteString ( "Form", "Caption", Caption );
ini->WriteBool ( "Form", "InitMax",
WindowState == wsMaximized );
delete ini;
}

Each of the Read routines takes three parameters. The first parameter identifies the section of the ini file. The second parameter identifies the value you want to read, and the third is a default value in case the section or value doesn't exist in the ini file. Just as the Read methods gracefully handle the case when a section or value does not exist, the Write routines create the section and/or value if they do not exist. The example code creates an ini file the first time it is run that looks like this:

[Form]

Top=185
Left=280
Caption=Default Caption
InitMax=0

On subsequent execution of this application, the ini values are read in when the form is created and written back out in the OnClose event.
