InnoSetup安裝之前檢查程序

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 setup
function 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;
           

關閉程序

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

停止服務

sc stop Process

删除服務

sc delete Process

//TStringList 常用方法與屬性:

var

  List: TStringList;

  i: Integer;

begin

  List := TStringList.Create;

  List.Add('Strings1');           {添加}

  List.Add('Strings2');

  List.Exchange(0,1);             {置換}

  List.Insert(0,'Strings3');      {插入}

  i := List.IndexOf('Strings1');  {第一次出現的位置}

  List.Sort;                      {排序}

  List.Sorted := True;          {指定排序}

  List.Count;                     {總數}

  List.Text;                      {文本集合}

  List.Delete(0);                 {删除, 0是第一個資料}

  List.LoadFromFile('c:\tmp.txt');{打開}

  List.SaveToFile('c:\tmp.txt');  {儲存}

  List.Clear;                     {清空}

  List.Free;                      {釋放}

end;

--------------------------------------------------------------------------------

//讀入字元串

var

  List: TStringList;

begin

  List := TStringList.Create;

  List.CommaText := 'aaa,bbb,ccc,ddd';

  //相當于: List.Text := 'aaa' + #13#10 + 'bbb' + #13#10' + 'ccc' + '#13#10' + 'ddd';

  ShowMessage(IntToStr(List.Count));  //4

  ShowMessage(List[0]);  //aaa

  List.Free;

end;

--------------------------------------------------------------------------------

//置換分隔符

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;

//類似的哈希表操作法

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 可以指派:

  List.ValueFromIndex[1] := '2';

  ShowMessage(List[1]);  //bbb=2

  //可以通過 Values 指派:

  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;

--------------------------------------------------------------------------------

//避免重複值

var

  List: TStringList;

begin

  List := TStringList.Create;

  List.Add('aaa');

  List.Sorted := True;  //需要先指定排序

  List.Duplicates := dupIgnore;  //如有重複值則放棄

  List.Add('aaa');

  ShowMessage(List.Text);  //aaa

  //Duplicates 有3個可選值:

  //dupIgnore: 放棄;

  //dupAccept: 結束;

  //dupError: 提示錯誤.

  List.Free;

end;

//排序與倒排序

{排序函數}

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);  //調用排序函數

  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;
