Vorbei bedingten parameter in Inno Setup

und so ein wenig Forschung Lesen und Lesen .. ich habe meine Antwort.

hier mein code (mit Ausnahme der "GetCommandLineParam")

[Code]
{
var
  StartNow: Boolean;
}

function GetCommandLineParam(inParam: String): String;
var
  LoopVar : Integer;
  BreakLoop : Boolean;
begin
  { Init the variable to known values }
  LoopVar :=0;
  Result := '';
  BreakLoop := False;

  { Loop through the passed in arry to find the parameter }
  while ( (LoopVar < ParamCount) and
          (not BreakLoop) ) do
  begin
    { Determine if the looked for parameter is the next value }
    if ( (ParamStr(LoopVar) = inParam) and
         ( (LoopVar+1) <= ParamCount )) then
    begin
      { Set the return result equal to the next command line parameter }
      Result := ParamStr(LoopVar+1);

      { Break the loop }
      BreakLoop := True;
    end;

    { Increment the loop variable }
    LoopVar := LoopVar + 1;
  end;
end;

{
function InitializeSetup(): Boolean;
var
  NOSTART_Value : String;

begin
  NOSTART_Value := GetCommandLineParam('/NOSTART');

  if(NOSTART_Value = 'false') then
    begin
      StartNow := True
    end
  else
    begin
      StartNow := False
    end;

  Result := True;
end;
}

procedure CurStepChanged(CurStep: TSetupStep);
var
  Filename: String;
  ResultCode: Integer;
  NOSTART_Value : String;
begin
  if CurStep = ssDone then
    begin
      NOSTART_Value := GetCommandLineParam('/NOSTART');
      if(NOSTART_Value = 'false') then
        begin
          Filename := ExpandConstant('{app}\{#MyAppExeName}');
          Exec(Filename, '', '', SW_SHOW, ewNoWait, Resultcode);
        end
    end;
end;

einem code-update. Dank @TLama

function CmdLineParamExists(const Value: string): Boolean;
var
  I: Integer;  
begin
  Result := False;
  for I := 1 to ParamCount do
    if CompareText(ParamStr(I), Value) = 0 then
    begin
      Result := True;
      Break;
    end;
end;

procedure CurStepChanged(CurStep: TSetupStep);
var
  Filename: String;
  ResultCode: Integer;
  NOSTART_Value : String;
  RunApp : Boolean;
begin
  if CurStep = ssDone then
    begin
      RunApp := CmdLineParamExists('/START');
      if(RunApp = True) then
        begin
          Filename := ExpandConstant('{app}\{#MyAppExeName}');
          Exec(Filename, '', '', SW_SHOW, ewNoWait, Resultcode);
        end

      //NOSTART_Value := GetCommandLineParam('/START');
      //if(NOSTART_Value = 'true') then
        //begin
          //Filename := ExpandConstant('{app}\{#MyAppExeName}');
          //Exec(Filename, '', '', SW_SHOW, ewNoWait, Resultcode);
        //end
    end;
end;
