InnoSetup安装之前检查进程

Answer1

This is something I did to prompt the user to close a program if it was found running.

function CheckProcessRunning( aProcName,                              aProcDesc: string ): boolean;var  ShellResult: boolean;  ResultCode: integer;  cmd: string;  sl: TStringList;  f: string;  d: string;begin  cmd := 'for /f "delims=," %%i ' +          'in (''tasklist /FI "IMAGENAME eq ' + aProcName + '" /FO CSV'') ' +          'do if "%%~i"=="' + aProcName + '" exit 1';   f := 'CheckProc.cmd';  d := AddBackSlash( ExpandConstant( '{tmp}' ));  sl := TStringList.Create;  sl.Add( cmd );  sl.Add( 'exit /0' );  sl.SaveToFile( d + f );  sl.Free;  Result := true;  while ( Result ) do  begin    ResultCode := 1;    ShellResult := Exec( f,                         '',                         d,                          SW_HIDE,                          ewWaitUntilTerminated,                          ResultCode );    Result := ResultCode > 0;    if Result and        ( MsgBox( aProcDesc + ' is running. This program must be closed to continue.'#13#10 +                  'Please close it and click Yes to retry or click No to cancel this installer.',                  mbConfirmation,                  MB_YESNO ) <> IDYES ) then      Break;  end;  DeleteFile( d + f );end;

I used it in the following special code sections as follows:

// Perform some initializations.  Return False to abort setupfunction InitializeSetup: Boolean;begin  // Do not use any user defined vars in here such as {app}  InitializeGlobals;  Result := not ( CheckProcessRunning( 'bcb.exe',      'C++ Builder' ) or                  CheckProcessRunning( 'delphi32.exe', 'Delphi'      ) or                  CheckProcessRunning( 'bds.exe',      'Rad Studio'  ));end;function InitializeUninstall: Boolean;begin  InitializeGlobals;  Result := not ( CheckProcessRunning( 'bcb.exe',      'C++ Builder' ) or                  CheckProcessRunning( 'delphi32.exe', 'Delphi'      ) or                  CheckProcessRunning( 'bds.exe',      'Rad Studio'  ));end;

关闭进程

closecmd := 'taskkill /F /IM process.exe';

停止服务

sc stop Process

删除服务

sc delete Process

//TStringList 常用方法与属性:
var
  List: TStringList;
  i: Integer;
begin
  List := TStringList.Create;
  List.Add('Strings1');           {添加}
  List.Add('Strings2');
  List.Exchange(0,1);             {置换}
  List.Insert(0,'Strings3');      {插入}
  i := List.IndexOf('Strings1');  {第一次出现的位置}
  List.Sort;                      {排序}
  List.Sorted := True;          {指定排序}
  List.Count;                     {总数}
  List.Text;                      {文本集合}
  List.Delete(0);                 {删除, 0是第一个数据}
  List.LoadFromFile('c:\tmp.txt');{打开}
  List.SaveToFile('c:\tmp.txt');  {保存}
  List.Clear;                     {清空}
  List.Free;                      {释放}
end;
--------------------------------------------------------------------------------


//读入字符串
var
  List: TStringList;
begin
  List := TStringList.Create;
  List.CommaText := 'aaa,bbb,ccc,ddd';
  //相当于: List.Text := 'aaa' + #13#10 + 'bbb' + #13#10' + 'ccc' + '#13#10' + 'ddd';


  ShowMessage(IntToStr(List.Count));  //4
  ShowMessage(List[0]);  //aaa


  List.Free;
end;
--------------------------------------------------------------------------------


//置换分隔符
var
  List: TStringList;
begin
  List := TStringList.Create;
  List.Delimiter := '|';
  List.DelimitedText := 'aaa|bbb|ccc|ddd';


  ShowMessage(IntToStr(List.Count));  //4
  ShowMessage(List[0]);  //aaa


  List.Free;
end;
--------------------------------------------------------------------------------


//类似的哈希表操作法
var
  List: TStringList;
begin
  List := TStringList.Create;


  List.Add('aaa=111');
  List.Add('bbb=222');
  List.Add('ccc=333');
  List.Add('ddd=444');
  List.Add('eee=');
  List.Add('fff');


  ShowMessage(List.Names[1]);  //bbb
  ShowMessage(List.ValueFromIndex[1]);  //222
  ShowMessage(List.Values['bbb']);  //222


  //ValueFromIndex 可以赋值:
  List.ValueFromIndex[1] := '2';
  ShowMessage(List[1]);  //bbb=2


  //可以通过 Values 赋值:
  List.Values['bbb'] := '22';
  ShowMessage(List[1]);  //bbb=22


  ShowMessage(List.Names[4]);  //eee
  ShowMessage(List.ValueFromIndex[4]);  //
  ShowMessage(List.Values['eee']);  //


  ShowMessage(List.Names[5]);  //
  ShowMessage(List.ValueFromIndex[5]);  //
  ShowMessage(List.Values['fff']);  //


  List.Free;
end;
--------------------------------------------------------------------------------


//避免重复值
var
  List: TStringList;
begin
  List := TStringList.Create;


  List.Add('aaa');


  List.Sorted := True;  //需要先指定排序
  List.Duplicates := dupIgnore;  //如有重复值则放弃


  List.Add('aaa');


  ShowMessage(List.Text);  //aaa


  //Duplicates 有3个可选值:
  //dupIgnore: 放弃;
  //dupAccept: 结束;
  //dupError: 提示错误.


  List.Free;
end;
--------------------------------------------------------------------------------


//排序与倒排序
{排序函数}
function DescCompareStrings(List: TStringList; Index1, Index2: Integer): Integer;
begin
  Result := -AnsiCompareText(List[Index1], List[Index2]);
end;


procedure TForm1.Button1Click(Sender: TObject);
var
  List: TStringList;
begin
  List := TStringList.Create;


  List.Add('bbb');
  List.Add('ccc');
  List.Add('aaa');


  {未排序}
  ShowMessage(List.Text);  //bbb ccc aaa


  {排序}
  List.Sort;
  ShowMessage(List.Text);  //aaa bbb ccc


  {倒排序}
  List.CustomSort(DescCompareStrings);  //调用排序函数
  ShowMessage(List.Text);  //ccc bbb aaa


  //假如:
  List.Sorted := True;
  List.Add('999');
  List.Add('000');
  List.Add('zzz');
  ShowMessage(List.Text);  //000 999 aaa bbb ccc zzz
end;
